[Prior Art] As a device which is formed into a linear spring by winding a wire, it is known as a device according to the patent document 1 (Japanese Patent Laid-Open No. 2004-237352), the wire is provided by a pressure feed. The wire feeding means of the roller is sent from the mandrel (wire feeding portion) to the forming platform, and is brought into contact with the coil forming tool which advances toward the linear spring forming platform from the direction orthogonal to the axis of the wire, and is wound up. For the coil. Further, the diameter of the formed coil changes in accordance with the distance between the coil forming tool and _, A^·τ4. That is, the diameter of the formed coil is such that the closer the distance between the forming tool and the mandrel is, the smaller the coil diameter is, and the larger the distance between the forming tool and the mandrel is, the larger the coil diameter is. Therefore, by the linear spring forming action, the mandrel is moved toward the axis and the line direction of the wire at a constant speed by the mandrel moving means (the mandrel is pulled away from the forming tool in an equal degree). When the wire fed at the same speed is applied to the coil forming tool, the wire is gradually changed (increased) along the axial direction to form a substantially conical open spring. 100112596 4 201143929 The use of wire with slightly different characteristics; Therefore, the convenient conical spring, the obtained load-bearing special: the conical spring of the shape made by the design of the range of the weight of the bribe variation: often not, in preparation, must be adjusted according to the wire lot number == Conical springs, so the adjustment of the load characteristics of the conical spring: Load:: raw work. It is done by completing the shape. For example, the inclination of the outer circumference of the conical spring in the direction of the conical mandrel, ", , /, the increase in the diameter of the coil in the coil changes, and the load characteristics in the direction of the center axis of the outer Ρ / σ coil are ingeniously changed. With respect to the inclination of the outer circumference of the spring, the linear spring forming device =:=: lamp ^ ' is as shown in ®17(b), which is similar to the Fuji mountain type 'near' cone type and approximate bowl type. Variety. Specifically, the setting of the linear magazine forming device fixes the moving speed of the mandrel to the constant speed ' and switches the transmission speed of the wire from the private (10) material & Fig. 7(a)' shows the setting of the wire conveying speed of the linear spring forming spring when the conical spring is formed, and Fig. 7(b) shows the completed shape corresponding to the setting. The horizontal axes of the upper left diagram and the upper right diagram of Fig. 7(a) respectively indicate the transmission time t of the wire from the through shaft. The component symbol 11 indicates the time until the wire conveyance speed is switched, and t2 indicates the total conveyance time of the wire. Eight's garden 100112596 5 201143929 The vertical axis of the upper left diagram of 7(a) indicates the conveyance amount X of the wire, and the vertical axis of the upper right diagram indicates the conveyance speed V of the wire from the through shaft. The horizontal axis 'in the lower left diagram of Fig. 7(a) indicates the movement time of the mandrel (t1, t2 is the same as the transmission time of the wire) t, and the vertical axis 'of the same figure indicates the moving distance p of the mandrel. . The mandrel is set as described above to set the linear spring forming device in such a manner as to move at a constant speed (pulled away from the coil forming tool) from P1 to P3 as shown in Fig. 7(b). On the other hand, the wire is set to be a linear spring forming device so as to be fed from the mandrel at a speed of two stages as shown in the upper right diagram of Fig. 7(a). The circumference of the coil of the conical spring formed by the linear spring forming device is longer than the vicinity of the start winding, of course, near the end of winding. Therefore, for example, as shown in the upper right diagram (two-point chain line portion) of Fig. 7(a), when the wire is fed at a constant speed V0 by a coil moving from P1 to P3 at a constant speed, as shown in Fig. 7 ( b) The circumference of the coil shown in the figure on the left will gradually increase from the start of winding to the end of winding, because the amount of conveyance (transmission speed) of the wire from the through mandrel does not increase and is constant, so when it is wound around the coil The moving ratio of the eccentric is gradually increased from the start of winding to the end of winding. Therefore, the inclination of the outer circumference of the conical spring with respect to the direction of the central axis of the coil LO is as sharp as shown in the left figure of the vicinity of the end of the winding. The result, as shown in _ 7_ left picture, if it will pass

[Progressive technical literature] [Patent Document 1] Patent Document 1: Japanese Patent Laid-Open No. 2004-237352 SUMMARY OF INVENTION [Problem to be Solved by the Invention] When forming a conical spring, an operator must obtain a predetermined load characteristic in a formed conical spring. So far, the constant velocity variable (a, b) in which the linear spring is placed in (4) is repeatedly set to countless readings. The mosquito is most suitable for the speed of the wire with a certain characteristic, Wei (a, b), #为为等速度 Wei The number of combinations of (Ο) is very large, so the operator will force a large amount of labor until the best combination is found, and it takes a lot of time. The jin, 疋 is suitable for a linear elastic molding device with a certain characteristic wire. The set value (7) is known as the equal speed Wei a, b) n is preferably as simple as possible 100112596 201143929 single and pure time. Therefore, the applicant of the present invention believes that, in the case of repeating, when the cone spring is formed, it is possible to reduce the number of variables for the formation shock input, and at the same time, the shape of the cone is completed in the same manner as conventionally. The change can be - edge _ load of miscellaneous, or Lai Neng ❹ (four) over the cone and yellow caused by the labor and time. x This month's hair has the above-mentioned problems in order to provide the value set by the linear spring forming device in the adjustment of the shape of the plurality of shapes that are skillfully not _conical springs (the conventional speed variable a = , number # The large towel field is reduced to the working time until the value is determined, and the operator is responsible for the load-bearing characteristic adjustment system. (Means for solving the problem) The load of the conical spring of the third invention for solving the above problem The characteristic adjustment system is a load-bearing characteristic adjustment system for performing round-turning forming through a wire spring forming device having a wire feeding means, a cooker, a screwing means, and a winding diameter seasoning section; the wire feeding means is a wire rod The wire drawing portion is fed in the axial direction of the wire; the forming tool is disposed at least one of the wire feeding portions, and the wire is fed out and wound, and the screwing means is The wire is wound in a spiral shape; the wire diameter adjusting means is formed by the wire feeding portion and the forming tool for feeding the wire to t Dynamically changing, the winding diameter of the wire, the gradual culture, the wire feeding means, and the wire feeding means, the wire is sent from the wire at an equal acceleration, and the equivalent acceleration of the (4) is adjusted to adjust the generation of the 1001J2596 201143929 The load characteristic of the conical magazine is used to adjust the load characteristic of the conical spring generated. (Action) The shape of the conical spring is changed by adjusting the acceleration of the input of the wire set by the linear spring forming device. It is a conical spring with different load characteristics. It is known to be carried out between the approximate Fujiyama type, the approximate cone type and the approximate bowl type, and the adjustment of the completed shape of the conical spring, that is, the adjustment of the load characteristics of the conical magazine, although The operator changes the "combination of the wire conveying speeds from the wire feeding portion (for example, a, b)" set by the linear spring forming device to change the shape of the completed shape of the conical spring, but because of the number of combinations as described above It’s huge, so it’s up to the “wire transfer speed combination” of the wire that has the right characteristics. However, the load-characteristics adjustment system of the conical spring of the first invention of the present invention is not changed by the "combination of the wire conveying speed" but by a constant acceleration from the wire feeding portion. The "conveyance acceleration of the wire" that is sent out is approximately between the Mt. Fuji type, the approximate cone type, and the approximate bowl type, and it is possible to adjust the shape of the conical spring similar to the conventional one. In other words, the load of the conical spring of the first invention of the present invention is In the characteristic adjustment system, the setting item of the linear spring forming device for changing the shape of the conical spring has only one item of "conveying acceleration of the wire". Therefore, if the "combination of wire conveying speeds" of two or more items is not set, With the change, the conventional adjustment system 100112596 10 201143929, which is unable to obtain the same shape change as the present case, has fewer testers (the number of known tests is the square of the set value). That is, the number of tests and the work time until the set value (which is the acceleration in the present invention) which is most suitable for the wire is substantially reduced. Further, the load characteristic adjustment system of the conical magazine of the second invention is formed by using a linear spring surface I of an eight wire material feeding means, a forming tool, a screwing means, and a winding diameter adjusting means to form a conical spring. The load characteristic adjustment system is a method in which the wire feeding device sends the wire from the wire feeding portion to the axial direction of the wire; the forming jade is relatively oriented to the wire feeding portion to the above arrangement The wire is wound and merged to perform winding; the screwing hand & is to make the winding of the wire into a spiral shape; the winding section is the wire which is sent out by the silver wire which is good in the line and the raw material of the mountain The distance between the delivery portion and the forming tool (4) is changed by the movement g, and the winding diameter of the wire is gradually changed; wherein the winding device is such that the material feeding portion of the wire feeding towel is one of: The acceleration is moved, and by adjusting the equal acceleration of the movement, the load characteristic of the generated cone spring is adjusted, and the load characteristic of the "turned" is generated. In the second invention of the present invention, the second invention of the present invention is used to replace the adjusting wire in the first invention of the present invention, and the acceleration is changed to the side of the wire feeding portion or the winding by the winding diameter adjusting means, and the wire feeding portion is invited to move at the same acceleration. The distance of a tool changes, and the shape change of the shape of the cone-shaped spring is adjusted by adjusting the above-mentioned movement, and the load of the cone spring is adjusted to make the circle, in other words, the load characteristic adjustment system of the conical spring of the second invention of the present invention, 201143929 The setting item of the linear elastic molding device for changing the shape of the conical spring is only one item of "moving acceleration of one of the wire feeding portion or the forming tool". Therefore, if two items or more are not used, "the wire conveying speed is not performed." The number of tests for the conventional adjustment system that cannot obtain the same shape change as the present case is small (the number of conventional tests is the square of the set value). In other words, the number of tests and the operation time until the optimum set value of the wire material (according to the present invention is the acceleration) can be greatly reduced, and the load characteristic adjustment system of the conical spring of the third invention is utilized. A linear spring forming device having a wire feeding means, a forming tool, a screwing means, and a winding diameter adjusting means for adjusting a load characteristic during the forming of the conical spring, wherein the wire feeding means separates the wire from the wire feeding portion along the wire Sending in the axial direction; the forming tool is disposed at least with respect to the wire feeding portion and causing the fed wire to be wound and wound; the screwing means spiraling the wire; the roll The winding adjustment means changes the winding diameter of the wire by dynamically changing the distance between the wire feeding portion and the forming tool during the wire feeding; and +, the screwing means is capable of rotating the wire Swinging in the direction of the step of the conical spring and moving along the forming direction of the conical spring And in order to make the wound wire into a spiral pitch tool at a pitch corresponding to the above-described movement amount, the pitch of the spiral is gradually changed by moving the pitch tool at an equal acceleration, and By adjusting 100112596 12 201143929 == degrees 'adjust the generated load characteristics of the round essence '俾5 weeks, the load characteristics of the cone magazine. The load-bearing characteristics of the cone-shaped yellow can be adjusted even by changing the space between the cones (4). In the case of the case, the symmetry of the conical impellers, the μ goods, and the spacing of the pitches, / ° moved by 4 accelerations to accelerate the above-mentioned spacing tools of the above-mentioned spirals. The change is made, and the load of the conical magazine is adjusted. In the third case of the case, the load characteristic adjustment system of the conical spring is based on the linear spring forming device for changing the shape of the conical magazine. The "movement acceleration" is only a single item. Therefore, if the setting of the "combination of the wire transfer speeds" of two items or more is not performed, the number of tests for the conventional adjustment system that cannot be changed in the same shape as the case is small. The number of tests, which is the square of the set value). That is, the number of tests and the work time until the optimum set value for the wire (acceleration in the present invention) is obtained can be greatly reduced. (Effect of the Invention) The setting condition of the linear spring forming device of the conical spring according to the invention of the present invention is not a combination of two or more when the shape of the conical spring is changed. In the case of the item, since the number of tests until the set value of the linear magazine forming device necessary for obtaining the wire having the specific characteristics is reduced, the determination of the set value is changed to 100112596 13 201143929, and the work time and the work are greatly reduced. The load of the person. [Embodiment] A first embodiment of the present invention relating to a coil spring forming device (winding machine) will be described with reference to Figs. 1 to 5 .

將線形彈簧成形裝置設定成為V=a(t-tl)+V0,形成線材從線 材送出部依既定的等加速度送出狀態。元件符號a，係關於 加速度的變數(例如從0至100為止之由作業者以手動所變 更設定為0以上的整數等）。元件符號t，係線材傳送的經過 時間，元件符號tl，係成為tl<t2的既定之時間之固定值（元 件符號t2，係線材的總傳送時間），元件符號V0係關於既 定之等速度的固定值。作業者，係預先對線形彈簣成形裝置 設定固定值(t2、tl、V0)，再藉由將變數a的設定改變為0、 1、2、…100而一邊改變線材的傳送加速度一邊試製圓錐彈 簧，反覆試製至獲得既定之載重特性為止。 若將變數a變得更大，以時間tl、速度V0的位置為中心， 則速度的斜率，即加速度會變大。此時的線材傳送量，係如 圖8(a)左上圖所示。即，當a=0時，線材傳送量成為X=V〇xt， 因為從線材開始傳送朝向傳送結束，相對於中心軸L0之圓 錐彈簧外周的傾斜逐漸地變急劇，所以形成如圖8(b)之左圖 所示的近似富士山型之圓錐彈簧。 另一方面，若作業者將關於加速度的設定值a增大為 a=l、2、3，則線材傳送量 X 便成為 X=a/2xt2+(V0-axtl)xt， 而送出如圖8(a)左上圖的實線所示之加速度之曲線狀。即， 線材，係相較於設定為a=0時，因為於前半段被缓慢地送 出，而於後半段被快速地送出，所以相對於中心軸L0之圓 100112596 20 201143929 錐彈簧外mn貞斜m輯傳送的前半段與後半段大致 一定。其結果，圓錐彈簧的完成形狀，於既定值a時，係成 為如圖8(b)之中央圖所示的「近似錐裂」。 再者，§作業者將變數&設定為較上述「既定值a」大時， 如圖8(a)左上圖的單點鏈線所示，因為前半段的線材傳送變 得更緩慢，而後半段的線材傳送則變得更快速，所以圓錐彈 簧的傾斜，係成為於線材傳送的前半段為急劇，而後半段為 緩和。其結果’圓錐彈箐的完成形狀，在某值a時，係成為 如圖8(b)之右圖所示的「近似碗型」。 作業者’如上所述，針對具有特定之特性的線材’若將關 於線材之傳送加速度的變數僅1個項目從例如a=0變更為 1、2 1 、 .....00為止，便可使圓錐彈簧的完成形狀從近似富士 _里si地憂化為近似碗型為止（或使間距之增加比例不 同）’俾可調節所獲得的載重特性。當反㈣製形狀不同的 圓錐彈簧，使所獲得之載重特性涵蓋於既定範圍時的設定值 a，係因為成為其批號之騎的最佳值，所以若以設定值& 量產圓錐彈簧，便可量產具有目標载重特性的圓錐彈簧。作 業者，係只要變更設㈣於加速度的變數—個㈣便可調節 載重特性，並無必要如習知的「速度之组合」變更2項以上 的變數。所以，藉由可^確定具有既定之特㈣線材之最 錐彈簧的載重特 佳設定值a，便可輕易地調節所獲得之圓 性 100112596 21 201143929 再者，於本實施例中，雖然將端部加工車刀16〇(滑動平 台161)的移動速度固定為等速度，調節從線材送出部 所送出的線材1之等加速度俾使圓錐彈簧的完成形狀產生 變化，但亦可與此相反，即便在捲線機150的設定時，例如， 將線材1的傳送固定為等速度，使滑動平台161以滿足圖8 左上圖、右上圖之條件(使滑動平台161的移動量為χ、移 動速度為V之定義式滿足）的等加速度進行移動’並調節其 移動的等加速度(調節關於加速度的設定值a)，亦可使圓錐 彈簧的完成形狀，同樣地產生（從近似富士山型至近似碗型 為止）變化俾可進行載重特性的調節。又，當朝圓錐彈簧的 中心轴X2可進退地將複數個端部加工車刀16〇進行複數個 配置時（未圖示），使各自所搭載的滑動平台161以滿足圖8 左上圖、右上圖之條件的等加速度進行移動，而調節其移動 的等加速度。 另一方面，圆錐彈簧的載重特性，係利用使圓錐彈簧的間 距態樣產生變化亦可進行調節。由圓錐彈簧所產生的載重， 係當使小直徑側的間距調節變大、大直徑側的間距調節變 小，便變弱，而當使小直徑側的間距調節變大、大直徑侧的 間距調節變小，則相反地變強。 從此種觀點，圓錐彈簧的載重調節，亦可以上述圓錐彈簣 滑動平台161(端部加工車刀160)的移動加速度調節與線材 傳送加速度調節取代，改為藉由朝圓錐彈簧成形方向（CF方 100112596 22 201143929 向）以等加速度移動的間距卫具154之移動加速度調節亦可 進行。 當藉由未圖示之致動器機構的控制使間距卫具154在使 圓錐彈簧成形的CF方向上以等加速度移動時，使圓雜彈菁 ‘的間距朝圖6的CF方向加速度地增加。當調節間距工具154 .的^料加速料，因為間㈣增加態樣產生變化，使圓錐 彈簧的完成形狀出現巧妙地變化，所以可進行於圓錐彈菁所 狻得載重特性的調節。 所以，在捲線機15〇的設定時，例如，將來自線材送出部 158的線材1之傳送速度(或加速度）、與滑動平台161之移 動的速度（或加速度）予關定，若使間距工具154以滿足圖 8左上圖、右上圖之條件(使間距工具154的移動量為χ、移 動速度為V的定義式滿足)之等加速度進行移動，並調節其 移動勺等力σ迷度(調節關於力口速度的設定值a)，便可對應圓 錐彈貫的間距增量之變化使完成形狀產生變化’以進行載重 特性的調節。 於當時，作業者，關於捲線機150的設定，若僅將關於滑 動平σ 161的移動加速度（當以間距工具154的移動加速度 •調=進行载重特性之調節時，則為間距工具的移動加速度） 之=數1個項目例如從a=0變更至1、2、".100為止，便可 使圓錐彈簧的完成形狀從近似富士山裂巧妙地變化至近似 碗型為止（或僅間距之增加比例為不同） ’便可調節所獲得的 100112596 23 201143929 載重特性。若反覆試製形狀不同的圓錐彈簧，只要以所獲得 之載重特性涵蓋於既定範圍時的設定值a量產圓錐彈簀，便 可利用該批號的線材，量產具有目標之載重特性的圓錐彈 簧。作業者，只要變更設定關於加速度的變數一個種類，便 可輕易地調節所獲得之圓錐彈簧的載重特性。 接著，對可成形之圓錐彈簧的線形彈簧成形裝置之第2 實施例利用圖9至圖12進行說明。 與將線材送出部158予以固定並使端部加工車刀160側進 行移動的第1實施例相反，第2實施例的線形彈簣成形裝置 300，係將相當於端部加工車刀160的線圈成形工具120予

At the end of the action, ιΓ _ advances and retracts the tool (10) along the axis X1 of the wire (the roll adjustment means 'but in the winding machine 15 '' can also be arranged radially around the spool χ 2 (not shown), And by ===: the turning tool is 16° in the middle, and the direction of the coil is formed by the movement in the 2 direction by the movement _ travel u. == The direction of extension of the bent wire 1 is arranged adjacent to the heart. And the wire 1 is brought into contact with the pitch of the front end 154. At the front end of the spacing tool m, the wire is bent from the bent wire toward the coil forming direction (CF direction), and the coil is formed. In the direction (CF direction), the pressing portion 167 is pressed, and the reference numeral 54 is formed by an actuator mechanism (not shown) or the like in the direction of FIG. 4 or the opposite direction to the cf of the straight line X3. The direction of the second direction is the same as that of the straight line illusion. 100112596 17 201143929 As shown in Figs. 4 and 5, the wire feeding portion 158 is fed out, and the abutting groove of the turning tool 160 is processed by the end portion. The wire 1 which is curved on the surface orthogonal to the direction in which the coil spring is formed is formed by the bent inner side Guided to the core 153, one side is in contact with the pressing portion 167 of the distance guard 154. The wire 1' contacting the pressing portion 167 is pressed by being oriented toward the coil spring as shown in Fig. 6 It is spirally wound and formed into a coil magazine. After the coil spring is formed, the front end of the cutter which can be advanced and retracted toward the forming platform is pressed against the portion of the wire 1 to be cut and cut. The pitch of the formed coil springs is such that the ratio of the distance that the wire 1 moves from the guard 154 to the direction of the CF in the direction of the pressing portion 167 becomes larger, and the smaller the return to the CR direction, the smaller the smaller. . The formation of the conical shape is carried out by gradually increasing or decreasing the diameter of the coil as the winding of the wire 1 is performed. In the winding machine i5G according to the first embodiment of the present invention, for example, a cam motor (not shown) is controlled as shown in Fig. 6, and the sliding platform (6) along which the turning tool 16 is mounted is mounted at a predetermined speed. The axis χι moves to the right (TR direction) so that the end of the urging force is gradually pulled out from the wire σίΜ 58 and pulled away by the wire 1 which is added from the wire feeding portion 158 by a predetermined amount. The abutting groove 159 of the section plus jade turning tool 16G can form a conical spring. Alternatively, in contrast to the predetermined acceleration, the m moving table 161 (end machining tool 160) may be moved in the TR direction to cause the wire feeding portion 158 to be fed at a predetermined speed. Coincidence; 冓159 can form a conical spring. 100112596 201143929 II: The finished shape of the cone magazine is controlled by the following, when the reduction, ^ 161 (end end of the turning tool 16G) at the same speed (four) adjust the line to the second speed by adjusting When the wire is fed at a constant speed, the acceleration such as the sliding movement can be easily and freely adjusted between the approximate Fujiyama type, the approximate cone change, and the approximate bowl type. The control method of the linear spring forming device for forming the 1J cone magazine is shown in Fig. 8. As shown in Fig. 8 (8), the control method of each embodiment of the present invention. The horizontal axes of the upper left diagram and the upper right diagram of Fig. 8(a) indicate the elapsed time t of the wire conveyance from the line #"^ portion 158, respectively, and the vertical axis 'in the upper left diagram indicates the respective pieces from the wire feeding portion 158. The wire conveyance amount χ, the vertical axis ' in the upper right diagram above indicates the wire conveyance speed V from the wire feeding portion 158. The horizontal car in the lower left diagram of Fig. 8(a) indicates the sliding platform on which the end machining tool is mounted. The movement time t of 161 is the vertical axis of the lower left diagram, which indicates the movement amount ρ of the slide platform 161. The end processing tool 16 〇 (sliding table 161) is numerically controlled by a cam motor (not shown) so that the wire 1 sent from the wire feeding portion 158 is aligned with the abutting groove 159, the edge axis XI moves t2 at a constant speed. The time moves from ^ to Ρ3β in the lower left figure of Fig. 8(a). When the motor is controlled by a motor (not shown), the wire is sent out from the wire feeding unit as shown in the upper right figure of Fig. 8(a). When the transmission speed of the wire of 158 is always equal to the constant speed V ,, as shown in the left diagram of FIG. 8( b ), an approximately Fuji-type type in which the center of the outer peripheral surface of the conical spring is recessed toward the inside is formed. Conical spring. 100112596 19 201143929 In the present embodiment, the linear spring forming device is set to V=a(t−tl)+V0 as shown in the upper right diagram of FIG. 8(a), and the wire is formed from the wire feeding portion. The given constant acceleration is sent out. The component symbol a is a variable relating to acceleration (for example, an integer from 0 to 100 which is manually changed by the operator to 0 or more). The component symbol t is the elapsed time of the wire conveyance, and the component symbol t1 is a fixed value of the predetermined time of t1 <t2 (the component symbol t2, the total transmission time of the wire), and the component symbol V0 is about the predetermined speed. Fixed value. The operator sets a fixed value (t2, tl, V0) to the linear magazine forming device in advance, and then changes the transmission acceleration of the wire while changing the setting of the variable a to 0, 1, 2, ... 100. The spring is repeatedly tested until the desired load characteristics are obtained. If the variable a is made larger, centering on the position of time t1 and speed V0, the slope of the speed, that is, the acceleration becomes large. The amount of wire conveyance at this time is as shown in the upper left diagram of Fig. 8(a). That is, when a = 0, the wire conveyance amount becomes X = V 〇 xt, because the inclination of the outer circumference of the conical spring with respect to the central axis L0 gradually becomes sharp as the conveyance starts from the wire toward the end of conveyance, so that it is formed as shown in Fig. 8 (b). ) The Fujiyama-type conical spring is shown on the left. On the other hand, if the operator increases the set value a about the acceleration to a=l, 2, 3, the wire conveyance amount X becomes X=a/2xt2+(V0-axtl)xt, and is sent as shown in Fig. 8 ( a) The curve of the acceleration shown by the solid line in the upper left diagram. That is, when the wire is set to a=0, since the first half is slowly sent out and the second half is quickly sent out, the circle with respect to the central axis L0 is 100112596 20 201143929. The first half and the second half of the m series are roughly fixed. As a result, the completed shape of the conical spring is "approximate taper" as shown in the center diagram of Fig. 8(b) at a predetermined value a. Furthermore, if the operator sets the variable & greater than the above-mentioned "established value a", as shown by the single-dot chain line in the upper left diagram of Fig. 8(a), since the wire transfer in the first half becomes slower, The wire conveyance in the second half becomes faster, so the inclination of the conical spring is sharp in the first half of the wire conveyance and the second half is gentle. As a result, the finished shape of the conical magazine is a "approximate bowl type" as shown in the right figure of Fig. 8(b) at a certain value a. The operator's as described above, for a wire having a specific characteristic, if only one item of the variable of the transmission acceleration of the wire is changed from, for example, a=0 to 1, 2 1 , .....00, The shape of the conical spring is adjusted from approximately Fujito to approximately the shape of the bowl (or the ratio of the increase in the pitch is different). The load characteristics obtained can be adjusted. When the conical springs of different shapes are made in the opposite direction (4), the set value a obtained when the obtained load characteristics are covered by the predetermined range is the optimum value of the ride of the batch number, so if the conical spring is produced at the set value & It is possible to mass produce conical springs with target load characteristics. The operator can adjust the load characteristics by changing the (four) acceleration variable—(4), and it is not necessary to change two or more variables as in the conventional “speed combination”. Therefore, the circularity obtained can be easily adjusted by determining the load setting value a of the most tapered spring having the predetermined special (four) wire. 100112596 21 201143929 Furthermore, in this embodiment, although the end The moving speed of the machining tool 16 〇 (sliding table 161) is fixed at a constant speed, and the acceleration of the wire 1 sent from the wire feeding portion is adjusted to change the shape of the completed shape of the conical spring, but it may be reversed. At the time of setting of the winding machine 150, for example, the conveyance of the wire 1 is fixed at a constant speed, so that the sliding table 161 satisfies the conditions of the upper left diagram and the upper right diagram of FIG. 8 (the movement amount of the slide platform 161 is χ, the moving speed is V The constant acceleration of the defined expression satisfies and adjusts the constant acceleration of the movement (adjusting the set value a with respect to the acceleration), and the shape of the conical spring can be similarly generated (from the approximate Fujiyama type to the approximate bowl type). The change 俾 can adjust the load characteristics. Further, when a plurality of end-end machining tools 16 are arranged to advance and retreat toward the central axis X2 of the conical spring, a plurality of end machining tools 16 are arranged (not shown), and the slide platforms 161 mounted thereon are provided to satisfy the upper left diagram and the upper right side of FIG. The iso-acceleration of the condition of the graph moves and adjusts the iso-acceleration of its movement. On the other hand, the load-bearing characteristics of the conical spring can be adjusted by changing the distance between the conical springs. The load generated by the conical spring is such that the pitch adjustment on the small diameter side becomes larger, the pitch adjustment on the large diameter side becomes smaller, and becomes weaker, and the pitch adjustment on the small diameter side becomes larger, and the pitch on the large diameter side becomes larger. As the adjustment becomes smaller, it becomes stronger on the contrary. From this point of view, the load adjustment of the conical spring can also be replaced by the movement acceleration adjustment of the above-described conical magazine sliding platform 161 (end processing turning tool 160) and the wire conveying acceleration adjustment, instead of forming direction toward the conical spring (CF side) 100112596 22 201143929 The movement acceleration adjustment of the distance guard 154 moving at an equal acceleration can also be performed. When the pitch guard 154 is moved at an equal acceleration in the CF direction in which the conical spring is formed by the control of an actuator mechanism (not shown), the pitch of the circular ampoule "incensively increases toward the CF direction of FIG. . When the material of the pitch tool 154 is adjusted, the change in the shape of the (4) is changed, and the shape of the cone spring is subtly changed, so that the adjustment of the load characteristics of the cone can be performed. Therefore, at the time of setting the winding machine 15A, for example, the conveying speed (or acceleration) of the wire 1 from the wire feeding portion 158 and the speed (or acceleration) of the movement of the sliding table 161 are predetermined, and if the spacing tool is used 154 is moved to satisfy the acceleration of the condition of the upper left diagram and the upper right diagram of FIG. 8 (the definition of the movement of the spacing tool 154 is χ, the movement speed is V), and the force σ of the moving spoon is adjusted (adjustment) Regarding the set value a) of the force port speed, the change in the shape of the finished shape can be made corresponding to the change in the pitch increment of the conical bullet to adjust the load characteristic. At that time, the operator, regarding the setting of the winding machine 150, if only the movement acceleration with respect to the sliding level σ 161 (when the movement characteristic of the spacing tool 154 is adjusted = the load characteristic is adjusted), the movement acceleration of the spacing tool is For example, if the number of items is changed from a = 0 to 1, 2, ".100, the shape of the conical spring can be changed from approximately Fujiyama to approx. (or only the pitch). The ratio is different) 'The 100112596 23 201143929 load characteristics obtained can be adjusted. If the conical springs having different shapes are repeatedly produced, the conical springs having the target load characteristics can be mass-produced by mass-producing the conical magazines with the set value a when the obtained load characteristics are covered in the predetermined range. The operator can easily adjust the load characteristics of the obtained conical spring by changing the type of the variable with respect to the acceleration. Next, a second embodiment of a linear spring forming device for a formable conical spring will be described with reference to Figs. 9 to 12 . In contrast to the first embodiment in which the wire feeding portion 158 is fixed and the end machining tool 160 side is moved, the linear magazine forming device 300 of the second embodiment is a coil corresponding to the end machining tool 160. The forming tool 120 is fixed and moved by the side of the mandrel 10 corresponding to the wire feeding portion 158 toward the axis XI of the wire to adjust the shape of the conical magazine and the load characteristics. In the drawings, the linear spring forming apparatus 300 shown in this embodiment includes a wire feeding means 20 and a coil forming tool 120, and the coil forming tool 120 is advanced toward the forming platform 100, and by the pair The wire 1 sent from the front end portion of the mandrel 10 to the forming platform 100 is wound and combined, and is formed into a coil spring. The wire feeding means 20 has pressure feed rollers 22, 22 that feed the held wire 1 through one of the front forming platforms 100 (see FIG. 9) via the mandrel shaft 105 guided by the wire; The forming tool 120 is capable of advancing and retracting toward the forming platform 100. The component symbol 3, the fixed frame provided on the gantry 2, is fixed to the fixed frame 100112596 24 201143929 3 'the axis χ of the wire 1 is advanced and retracted along the axis 1 of the wire 1 and is provided with a dynamic change of the coil forming tool A linear way silde 50 that is spaced apart from the mandrel 10 (the winding diameter adjusting means after the first invention of the present invention). In other words, in the fixed casing 3, the slide shaft 52 in which the mandrel shaft 10 and the wire feeding hand 20 are integrally mounted via the slide frame 4 is slidably assembled to the axis XI along the wire 1. The integrated mandrel shaft 10 on the sliding platform 52 is driven by a ball screw 54 that is rotationally driven by a servo motor M50 provided on the fixed frame 3, along the axis XI of the wire 1 in the KF direction as shown in FIG. Or the KR direction can be advanced and retracted. The pressure feed rollers 22 and 22' of Fig. 9 rotate the upper roller 22 in the counterclockwise direction by the driving force of the drive motor m22 via a gear mechanism (not shown), and the lower roller 22 rotates clockwise and The held wire 1 is conveyed from the mandrel 1〇 to the forming platform 1〇〇. Further, a linear silde 11G is disposed above a direction orthogonal to the axis XI of the wire 1. Here, the linear slider U gentleman i*/ice A m . carries the coil forming tool 120

The tool rotating unit 13 of the tool holder 132 of the rotating body of the direction and the parallel rotating shaft 133 is configured by a servo motor M132 that rotates the rotating unit 131. The component symbol 132a is a gear rotatably coupled to the output shaft of the servo motor M132. The component symbol n3a is a gear rotatably coupled to the rotating shaft 133. The two gears 132a and i33a mesh with each other to transmit the motor driving force to the gear. Rotating unit 131. In the coil forming tool 120C, since the servo motor M132 is driven, since the arrangement of the right flexing tool body 134A and the left flexing tool body 134B can be reversed, the platform 100 can be easily switched in accordance with the configuration. The right-handed and left-handed tool bodies 134A and 134B of the wire 1 are used. Further, as shown in Fig. 11 (a), (b), and (c), in the left and right side corner portions of the flat rectangular block-shaped tool holder 132, the grooves (136a, 137a) for forming the wire engagement are individually formed. The wire abutting faces (136, 137) are disposed in the opposite directions to the right flexing tool body B4A and the left flexing tool body 134B. As shown in Fig. 11(b), the engaging groove 136a for right-handing is a pair of parallel grooves which are inclined downward to the right, and are not shown in Fig. 1(c). The engaging groove 137a for the left side is a pair of parallel grooves that are inclined downward to the left toward the left end of the tool body 134B. When the coil spring is formed, the coil forming tool 120 is advanced toward the forming platform 1 toward the cF direction of FIG. 1 by the control of the tool sliding platform 112, and the tool body 134A (or 134B) is disposed at 100112596 26 201143929. The opposing direction of the mandrel 1' is in contact with the wire 1 fed from the front end portion of the mandrel 10 toward the forming platform 1〇0. When the right-flexing tool body 134A is in the opposing direction of the mandrel 10, the wire abutting groove l36a which is inclined downward in the right-hand side of Fig. 11(b) is wound by right-handing as shown in Fig. 12 . Also, the tool holder 132 is rotated 180 by the servo motor Vil32. When the left-handing tool body 134 is placed in the opposing direction of the mandrel 10, the wire 1 is wound by the left-side inclined wire abutting groove 137a to the left. The winding diameter of the formed coil spring is increased in proportion to the distance between the tool body 134A (or 134B) and the mandrel 10. Therefore, when forming a conical spring as shown in Fig. 12, for example, the sliding platform 52 mounted on the mandrel 10 for feeding the wire at an equal acceleration is controlled by the numerical value of the vocal motor M50. The KR direction of 10 is moved at a constant speed, and the wire 1 is pulled away from the tool body 134A (or 134B), and the wire 1 is brought into contact with the wire abutting groove 136a (or 137a). Alternatively, the slide platform 52 mounted on the center of the core shaft 1 at the same speed is moved by the constant acceleration along the axis XI toward the KR direction of the left diagram 10 by the control of the servo motor M5 , while the wire 1 is moved. It is sufficient to abut the wire abutting groove 136a (or 137a). Further, at the time of setting the linear spring forming device 3A, for example, the movement of the slide table 52 (the through shaft 10) is fixed at a constant speed, and the wire 1 is made to pass from the mandrel (7) to the upper left diagram of FIG. The condition of the upper right picture (the acceleration of the wire 1 is X, the transmission speed is defined by the definition of v) is sent, and 100112596 27 201143929 adjusts the constant acceleration of the wire transmission (adjusting the set value of the acceleration, or vice versa) The conveying speed of the wire rod from the mandrel 1G is fixed to the constant speed, and the sliding platform 52 (the through shaft 1〇) is satisfied to satisfy the conditions of the (four) upper left diagram and the upper right diagram (the movement of the sliding platform 52 is X, The specific acceleration of the movement speed is V, and the acceleration of the acceleration is set at the acceleration value a), so that the cone is equal to its acceleration (° the load obtained by the Zhoulang joint (4). (4) The shape changes, the 俾 is adjustable At that time, the operator, when setting the on-line reshaping device 300, only transmits the acceleration of the wire 1 (or when the load is controlled by the movement of the sliding platform 52) 彳a ' Project example For example, from a=:〇 to 1,2,...100, # can make the shape of the conical spring make the Tianshishan type subtly change to the approximate peach type (or the load characteristic that increases the spacing.
