[Prior Art] In the conventional powder compacting apparatus, the powder is supplied from the powder source into the filling shoe, and then from the filling shoe into the compacting cavity in the compacting mold. When the compaction is completed, the filling shoe is removed from the hole of the compacting cavity by moving the filling shoe, and then the punch strongly presses the powder in the compacting cavity. We have found that in most cases, the density and performance of the final product will vary in an unsatisfactory manner. Density and performance will vary between different bodies and/or single bodies of the same product. Another uneven filling, such as a change in the amount of powder loaded in the cavity, results in an unsatisfactory weight change between the components produced. A method of solving the above-mentioned problems, the ancient and the earthworms, to design a powder compaction device, compared with the apparent density of the powder, the powder is added by adding the powder filled into the cavity. problem. For example, US 5,672,313 discloses a method in which the powder is applied to the package to have the same and high density; the powder is fed in this method package 126809.doc 200840706 includes pulsing the powder material in the shoe box until it is empty The powder density in the cavity is increased to at least u times the apparent density. In order to effectively vibrate the powder body in the shoe box, a plurality of top opening and bottom opening chambers composed of upright partitions are provided in the shoe phase. In each chamber, the powder is pulverized into a separate feed of slightly pre-compacted powder, and each of this feed will be provided to a different portion of the compacted cavity. According to this design, a higher packing density is formed. However, there are some risks in that there is a difference between the powder feeds from the chambers or that the feeds will not mix with each other in the interface between the feed chambers when filling the cavities. No. 3,893,791 discloses a device similar to that used to load a stamping die. In this device, the filling shoe has a grille therein. The grid is connected to the drive member to vibrate the powder feed. In this design, the grid is formed by the intersection of metal strips. This result design basically bears the same advantages and disadvantages as the design of 5,672,313. The change in elegant is often because the particles constituting the powder are easily connected or bonded together and the air is retained in the powder layer. Several methods for solving this problem have been proposed to achieve a uniform distribution of the powder in the compacted cavity so that the powder compact has a uniform density. A solution to __ is disclosed in us 3,972,449. The powder feed device depicted in this document includes a grid of 4-to-members that reciprocate to the grid at different rates during dispensing of the powder to the cavity. The grid is configured to fill the interior of the underlying shoe' and is reciprocable in a horizontal plane. The grid is preferably made of rods having a small pitch, but may also be formed by a network of wires, such as a mesh or a screen. The US 3,972,449 patent emphasizes that the lattice should not only vibrate back and forth but also the number of cycles per minute should be variable. The grid should be able to reciprocate hundreds of times per 126809.doc 200840706 minutes. This method includes a complex design with many active parts. At the same time, we have found that this design can lead to separation of the composite powder, which results in an unsatisfactory density distribution and fine particle dispersion such as graphite. Another risk, vibration, can cause the powder in the filling shoe to be less well packaged, which can result in uneven filling. In another conventional powder filling method disclosed in U.S. Patent No. 5,881,357, a conduit having a hole for venting is disposed in a powder box. When the powder enters the cavity, the gas is discharged to the powder in the powder box, so that the powder particles can move relative to each other. Because of the gas discharge, the powder can smoothly enter the second L without rotating in the cavity and smothering unevenly, so that the filling time period is shortened and the particle size distribution is uniform. However, such a design is very complicated and requires the supply of pressurized gas to the filling shoe. In another similar powder filling method disclosed in U.S. Patent No. 6,475,430, the material is extruded into a container by a pneumatic tapping method in which air pressure is alternately switched from a low air pressure state to a high air pressure state. By maintaining the low air pressure state equal to or higher than the presence of the gas pressure outside the space, it is possible to prevent the material from expanding upward due to the atmosphere flowing into the outside of the container. The material is then squeezed into the container. However, this design is more complicated and requires two different air and air. Therefore, there is still a need for improved apparatus and methods for filling powder into compacted cavities. SUMMARY OF THE INVENTION One object of the present invention is to provide a stable, sturdy, and simple structure for an enemy to solve the problem of the change in the shape of the body that is not required in the filled cavity. 200840706 This can be achieved in accordance with the present invention by a filling shoe device for transporting and dispensing powder into the empty body 15 of a powder compacting device, followed by compacting the powder; the filling shoe last includes - filling The shoe comprises: - an inlet portion for receiving powder into the filling shoe, - an outlet portion forming a powder outlet flow path having an outlet opening for the powder in the self-filling shoe An empty space allocated to the powder compacting device - a mesh structure disposed in the powder flow path, traversing the outlet hole, and wherein the mesh structure is fixedly disposed in the outlet portion and wherein the outlet Part of the fixation is fixed relative to the filling shoe device. It is an advantage of the present invention to provide a stable, strong and simple structure that simultaneously ensures uniform density of powder in the filled cavity. The invention is also potentially applicable to different types of existing compression devices without the need for costly modifications. The reticular tissue prevents the powder from joining and the trapped air can be discharged. Since the filling of the cavity is evenly within the volume of the cavity, the density of the powder in the cavity can be obtained. Further, it is possible to reduce the weight difference or weight dispersion of the pressed member. Another advantage is that the filling shoe device does not include moving parts, so there is no need to: insert the moving member. The mesh structure is immovable, that is, its mouth is disposed in the outlet portion, and the σ portion is fixed relative to the entire filling shoe device, whereby the machine is not applied or transferred for conveying the powder through the filling of the shoe. Force to fill the shoe device. By having the mesh tissue fixedly placed 126809.doc 200840706 in the π portion and the outlet portion relative to the entire filling shoe device system, then α has moving parts or members for operating the movement, and the filling will therefore be - Simple device, X requires minimal operation and maintenance. In addition, the technical features of the device can be easily applied and transferred to existing components, and the benefit of each is that existing devices can continue to be used without the need to replace them with new and special devices. and
網=織可以一距該出口孔小於10 mm，較佳為〇_7軸 内，取佳為(Μ mm之距離配置於該出口部分内。籍此阻止 粉體在其從網狀組織進人^腔之途中重組任何有效的橋。 另γ個優點是此允許網狀組織適應於各種粉體結構以便達 到取理想的充填效果。請注意到當決定網狀組織到出口孔 的距離時’與空腔形成界面之出口孔是適當的出發點。如 果形成出口孔之出口部分具備鎖定構件或類似物，這些在 决疋距離的時候是不計算入内的。在一具體實施例中，當 充填鞋在移動到空腔孔並從空腔孔移開時，形成網狀組織 之線與模具表面接觸。換句話說，與空腔相對的網狀組織 的表面是與界面平面或空腔之孔平面接觸的。 為了以最佳的方式來阻止橋接，故網狀組織具有的開口 大小為1-200 mm2，較佳地為ι-loo mm2。另一個優點是適 田地選擇開口的尺寸使得有可能讓網狀組織適應實際的粉 體結構。 在一些情況下，網狀組織最好只覆蓋充填鞋截面積的一 4分。據此特徵的另一個優點是可能適合使用之粉體。 充填鞋此外還可以包括能完全覆蓋出口孔的網狀組織。 126809.doc 200840706 此特徵使得其能夠有最理想的流量經過網狀組織這一優 點。另一個優點是使得縮短充填期變得可能。 在:個具體實施例中，充填鞋器件中的進Π部分的擴延 伸長、、工配置成可调即的，以用來調節該充填鞋中粉體的數 量。此為本發明的優點之一，因為並不需要有太多的粉體 • 力充填鞋器件中，由於進口部分中的空氣和充填鞋器件中 ‘ &空氣較佳地應該能通過網狀組織，所以過多的粉體在充 填鞋器件中可能中斷空氣通過網狀組織。因此藉由配置 • &/或調節進口部分向下延伸至充填鞋器件的距離，充填 鞋器件中粉體的數量可根據需要及有利數量來調節。 在-個具體實施例中，進口部分是一個如呈導管構件形 式的/;IL動道，其從一遠端朝最接近網狀組織的近端延伸， 並且配置於離該網狀組織之一距離處，該介於該流動道之 該近端和該網狀組織之間的距離是可調節配置的；該流動 道的近端以對該網狀組織成銳角配置，且該進口部分的出 口由一大致平行於該網狀組織的邊緣來界定。此具體實施 例的優點是因為出口邊緣大致與網狀組織平行，所以分配 粉體通過粉體流動道可為均句分佈粉體通過網狀組織=此 • 外，分配粉體可以一控制方法發生，且由於平行配置，故 可減少當粉體通過網狀組織時揚起的灰塵。 本發明涉及不同態樣，包括上述和下述的充填鞋器件， 及用於粉體充填和壓實的對應方法，及/或更進一步的器 件或產品構件，上述每項都產生一或多個與第一提及之熊 樣有關所描述之好處和優點，且每項都有相對於與第一提 126809.doc 11 200840706 二，態樣有關所描述及/或在附加請求中所揭示之具體實 施例之一或多個具體實施例。 八體實 r中進太步涉及一種充填粉體至粉體壓實裝置的空 法包含藉由充填鞋接收來自粉體來源的 a - 1〜體牙過-不可動地（即固定 出口部分之網狀組織；將於_…’置於充填鞋 ’將叔體從出口部分分配至該空腔， 其中輸送和分配粉體無需移動操作即可執行。 其中的—個優科此方法代表了—種 腔中之簡單、可靠和堅固的方法。 ^體至工 此方法可以句枯LV I t _ 匕括以下步驟··使用充填鞋器件，其中 鞋在分配粉體進入空腔時是 、 了疋口疋配置的。此特徵的優點即 ::包括較少步驟之簡化方法，和-具有較少機構的裝 八因$不需任何移動操作即可於充填鞋器件中執行輸送和 :=體’所以充填鞋器件和粉體虔實裝置可為簡單器件 =置，其所需要的操作和保養降到最少。所以藉由充填 土器件來輸运和分配或傳遞粉體至空腔是在沒有施加力至 充填鞋器件或執行充填鞋器件移動之情況下發生的；換句 話說相對於輸送或分配粉體 遞構件。此外，充填1^件了 Λ 不使用機械傳 異鞋器件可輕易地應用在現存的器件 中，例如粉體壓實裝詈，衿接 、 k樣的好處即為現存的設備可以 l使用而並不需要用新的和特殊的器件來替代。 的•、鲈…、體例中’此方法進-步包括壓實在空腔中 的秦體’從而形成壓實體。這樣就會形成一個具有均句密 126809.doc -12- 200840706 度的壓實體並且壓實部件之間較少有重量差異。更進一步 的優點為此方法代表一種用來壓實粉體之簡單、 固的方法。 此方法可以附加地包括燒結壓實體的步驟。 杈佳的是使用按照根據以上討論之用於充填和壓實粉體 • 壓實裝置之空腔中粉體的方法之較佳實施例中任一者的充 ， 填鞋器件。 在一些具體實施例中揭示了使用充填鞋器件之方法。 • 【實施方式】 在下面的描述中，參閱附加之圖式，此以圖解方式顯示 如何實行本發明。 圖1_2展現了 一個供用於粉體壓實裝置中之充填鞋之較 佳實施例。充填鞋丨基本上包括進口部分2、出口部分3和 網狀組織6。出口部分3形成具有出口孔5的粉體出口流動 道曰。粉體壓實裝置在模具中進一步包括空腔7。^中空腔 _ 7是環狀的，並利用位於模具之空腔中的砂心8。 根據圖1，充填鞋i是粉體壓實裝置的一部分。充填鞋工 在分配期間安置於粉體壓實裝置之空腔7之上。充填鞋^的 • 進口部分2經配置為能夠與粉體來源相連接的。充填鞋⑽ 出口部分3經配置為可釋放地連接至空腔7 ^ 圖2顯示充填鞋！的側視圖，並揭示充填鞋」之出口部分 3’其形成了具有出口孔5的粉體出口流動道；和網狀組織 6。網狀組織6固定地配置在充填鞋…丨口部分3。網狀組 織6配置在粉體流動道中橫越出口孔5。充填鞋…網狀組 126809.doc -13- 200840706 織6配置於距出口孔小於1〇職，較佳地在。_7賴，最佳 為〇·5腿之距離處。在此具體實施例中，網狀組織完全覆 盍住出π孔5。出口孔5在較佳實施例中可與空腔7之進口 孔形成界面。網狀組織6在距進口孔之該距離處沿該界面 延伸。 充填鞋！中之進口料2的擴延伸長在充餘】中可配置 為可調節的，以用來調節充填鞋！中粉體的數量。The net=woven may be less than 10 mm from the exit hole, preferably within the 〇7 axis, preferably (the distance of Μ mm is disposed in the outlet portion. thereby preventing the powder from entering the mesh structure Any effective bridge is recombined on the way of the cavity. Another advantage of γ is that this allows the mesh structure to adapt to various powder structures in order to achieve the desired filling effect. Please note that when determining the distance of the network structure to the exit hole, The outlet opening of the cavity forming interface is a suitable starting point. If the outlet portion forming the outlet opening is provided with a locking member or the like, these are not counted in the distance of the break. In a specific embodiment, when the filling shoe is in When moving to the cavity hole and moving away from the cavity hole, the line forming the network structure is in contact with the surface of the mold. In other words, the surface of the network structure opposite to the cavity is in contact with the plane of the interface or the plane of the cavity of the cavity. In order to prevent bridging in an optimal manner, the mesh structure has an opening size of 1-200 mm2, preferably ι-loo mm2. Another advantage is that the size of the opening is selected to make it possible to Tissue Adapting to the actual powder structure. In some cases, the mesh structure preferably covers only a quarter of the cross-sectional area of the filled shoe. Another advantage of this feature is that it may be suitable for use. Filling shoes may also include energy The mesh structure completely covers the exit orifice. 126809.doc 200840706 This feature makes it possible to have the most ideal flow through the mesh structure. Another advantage is that it makes it possible to shorten the filling period. In a specific embodiment The expansion and extension of the entrance portion in the filling shoe device, and the configuration of the inlet portion are adjustable to adjust the amount of the powder in the filling shoe. This is one of the advantages of the present invention because it is not required Too much powder • In the case of force-filled shoe devices, too much powder may break the air in the filling shoe device because the air in the inlet portion and the air in the filling device should preferably pass through the mesh structure. Through the mesh structure. Therefore, by configuring the &/or adjusting the distance from the inlet portion to the filling of the shoe device, the amount of powder in the filling device can be as needed and advantageous. In a specific embodiment, the inlet portion is an / in the form of a catheter member; the IL channel extends from a distal end toward the proximal end closest to the mesh tissue and is disposed away from the mesh At a distance from the tissue, the distance between the proximal end of the flow channel and the mesh tissue is adjustable; the proximal end of the flow path is configured at an acute angle to the mesh structure, and The outlet portion of the inlet portion is defined by an edge generally parallel to the mesh structure. The advantage of this embodiment is that since the outlet edge is substantially parallel to the network structure, the powder distribution can be a uniform distribution powder through the powder passage. By the mesh structure = this, the distribution of the powder can occur in a controlled manner, and due to the parallel configuration, the dust that is raised when the powder passes through the network is reduced. The present invention relates to different aspects, including the above Each of the above-described filling shoe devices, and corresponding methods for powder filling and compaction, and/or further devices or product components, each of which produces one or more of the first mentioned bears description Benefits and advantages, and each have with respect to the first mentioned particular 126809.doc 11 200840706 two, one aspect related to the embodiments described and / or disclosed in the additional request of one or more embodiments Specific embodiments.八体实 r中进太步 relates to a method of filling a powder to a powder compacting device comprising receiving a - 1~ body tooth from the powder source by filling the shoe - non-movable (ie fixing the outlet portion) Mesh tissue; will be placed in the filling shoe 'to distribute the unloading body from the outlet part to the cavity, where the conveying and dispensing of the powder can be carried out without moving operations.

The shape of the hole thus formed is square. The hole in Figure 3a is 8 mm x 8 mm, while the hole in the Figure is 4 mm in mm. In another embodiment, the aperture of the mesh structure 6 can be in the form of a circular aperture. Other shapes such as ellipse, rectangle, and diamond may also be considered. The preferred size of each well is hWO mm2. According to a specific embodiment, all of the holes in a known mesh structure 6 have the same size and shape. In this particular embodiment, the mesh structure 6 is formed from a metal wire, but in another embodiment, the mesh structure may be a perforated plate extending substantially along the boundary of the exit hole 126809.doc -14 - 200840706 or The analog is formed. In order to distribute the powder into the cavity of the compacting device of the powder compaction, the powder is received from the powder source and enters the inlet portion 2 of the filling shoe. The powder is transported through the interior of the filled shoe 1. In the outlet portion 3 of the surviving mad, and long dead fill shoe 1, the powder passes through the powder outlet and the α hole 5, thereby fixedly arranging the net across the outlet hole 5 in the powder flow path. Shape _6. The powder is thus distributed to the cavity 7.

Then, when the compacting body is pressed to further fill the shovel, the movement between the filled shoe last and the cavity 7 is performed by transferring the filling shoe 1, until the hole of the cavity 7 and the filling shoe i are filled. The exit holes are aligned. When the powder in the cavity 7 is to be pressed in real time, the relative movement between the filling shoe i and the cavity 7 is performed until the hole of the cavity 7 is under the punch. The powder is compacted by lowering the punch into the cavity 7. Or the exposed hole of the cavity 7 is partially covered by the mold, and the punch is introduced against the powder from the opposite direction - in this case, the punch is simultaneously lowered during the filling (ie, the enlargement of the cavity) can be used for manufacturing A slight pressure reduction makes it easy to fill the cavity. Accordingly, it is contemplated that the present invention can be adapted for use with different powder compacting devices utilizing different filling configurations, such as gravity filling and so-called suction filling. When the powder is dispensed into the cavity 7, the filling shoe last can be fixedly configured. The size and shape of the pores of the mesh structure 6 and the total area of the pores are parameters which can be adapted to match the particular powder supplied to the compacting device of the powder. In addition, the position of the outlet portion 3 to the network and the network The distance between the extensions of the lobes 6 is also a parameter which can be adapted to match the powder configuration of 126809.doc -15-200840706 to achieve a uniform density in the cavity 7. It is therefore possible for us to find a special mesh structure 6 design that matches a certain powder structure. The test results show that it is possible to reduce the weight dispersion of the preparation body by filling the fixed structure of the mesh structure 6 in the shoe. Even at higher filling speeds (hits/minutes), fewer standard deviations can be obtained. It is therefore possible to find an appropriate relationship between the design of the mesh structure 6 and the filling and compaction rates which result in the most ideal filling of the cavity 7. Two sets of exemplary experiments will be discussed in detail below. Example 1 The iron-based powder component was prepared according to pure iron powder ASC 100.29 purchased from HdganSs AB of Sweden. The powder component also contained 2·〇% copper powder 100 mesh, 0.8% graphite UF4, 0.8. % guanamine soil, bis-distearylamine. Transport the powder ingredients to the container located above the compaction equipment. A conduit descends from the valley to the filling shoe. The filling shoe has a width of 8 5 cm, a length of 8 · 5 cm, a front end height of 2.5 μm and a rear end height of 5 em. The bottom of the filling shoe is open. When the filling shoe is moved to a position above the cavity, it will then be used to fill the powder. After filling the cavity, the filling shoe is retracted and the compacting step begins. 2 环 rings with a height of 13 mm, an inner diameter of 19 mm and an outer diameter of 25 mm were pressed at a pressure of 600 MPa. The nominal weight is approximately 19 grams. The pressing speed was 14 strokes per minute. After suppressing the weight of each ring, the standard deviation of the weight is calculated. 126809.doc -16· 200840706 Thereafter, a meshed mesh structure with a mesh of 4 mm was installed on the bottom of the filled shoe. 200 rings were pressed at a pressing speed of 14 strokes per minute while the other 200 rings were pressed at a pressing speed of 16 strokes per minute. The weight of each ring is determined and the weight standard deviation is determined for each pressing speed. This was followed by a network with a grid of 8 mm size and the experiment was repeated. Table 1, experimental grid size according to example 1 (mm) number of rings pressing speed (h/min) standard deviation (g) meshless tissue filling shoes N/A 200 14 0.046 mesh-filled shoes 4 200 14 0.012 Mesh-filled shoes 4 200 16 0.021 mesh-filled shoes 8 200 14 0.029 mesh-filled shoes 8 200 16 0.022 From Table 1, we can notice that at the same pressing speed (14 kn/min Under the condition that the mesh tissue is placed in the filling shoe, the dispersion of weight is significantly smaller than when the mesh structure is not used. We can also note that the weight dispersion is still significantly smaller than the reference test (14 strokes per minute) even when the compression speed is increased to 16 strokes per minute. Example 2 _ Use the same experimental setup as in Example 1. The binder powder component based on pure iron powder ASC 100.29 purchased from HiSganSs AB also contains 2.0% copper powder 100 mesh, 0.8% graphite UF4, 0.8% guanamine wax, bis-distearylamine and 0.05% high.
