The present invention relates to a forging material automatic loading and conveying system, and more particularly to a forging material automatic loading and conveying system configured to automatically load and transfer of the forging material for hot forging operation.

In general, forging is a mechanical method of tapping or pressing a solid metal material with a hammer or the like to form a uniform shape. The temperature of tapping may be at room temperature, but forging materials with high melting point often require some heating.

Forging at a temperature higher than the temperature at which recrystallization proceeds in a forging material is called hot forging, and forging at a lower temperature is called cold forging. .

On the other hand, in order to make the structure of the solid material uniform and to reduce the size of crystal grains in the crystal solid, hammering operation is called annealing. The job of making a shape, or such a device, is called a forging press.

And working methods are: ① free forging to make the product of the desired shape by placing the material between flat tools and turning or changing the position properly, and ② molds with a certain shape. Two types of forgings are used to make products of the desired shape by sandwiching the material between them.

Tools for free forging include swage blocks, plates, set hammers, sledges, tongs, and taps, as well as anvils that have been well known in the past. Hammers used in forging operations include falling hammers, spring hammers, belt hammers, steam hammers, compressed air hammers for free forging, and drop hammers and conflict hammers for die forging. A drop hammer hits an upper die by dropping an upper die on a lower die, and a conflict hammer strikes each other by moving the upper die and the lower die. There are two methods of falling: falling freely by gravity, accelerating and falling with power, and hitting each other.

In addition, a tool used as a forging die or a hammer is required to withstand a strong impact under a certain temperature, so alloy steel is used.

The right ends of the third flow link 172c and the fourth flow link 172d are hinged at predetermined distances from the left end of the transfer grip 180 to the right, respectively.

Three pairs of the transfer grips 180 are installed side by side like the grip control device 160. That is, a first transfer grip 180a is formed in the first grip control device 160a, a second transfer grip 180b is formed in the second grip control device 160b, and a third grip control device 160c. A third transfer grip 180c is formed and operated therein.

On the other hand, although not shown, the central control unit is further provided on one side of the forging press (1). The central control unit controls the forging press 1, the autoloader 10, and the automatic transfer machine 100 to operate in conjunction with each other, and controls the respective devices by a user's input program.

Look at the action of the forging material automatic loading and transfer system according to the present invention having the configuration as described above.

First, a process of producing a product by hot forging will be described with reference to FIG. 8. First, the supplied material is cut into an appropriate size (step S190). And the cut material is heated to a high temperature while passing through a heater (not shown) (step S192). In other words, the forging material m is preferably heated to a temperature (for example, 1200 ° C.) or more at a temperature at which recrystallization of the material proceeds.

And the heated forging material (m) is automatically supplied to the forging press (1) by the automatic loading machine (10). The forging material (m) supplied to the forging press (1) is subjected to hot forging (step S194), the forging material (m) is completed, hot forging is moved to a separate facility (trimming) (step S196) . After the trimming process (step S196), the product is completed and taken out (step S198).

Next, a process in which the forging material m is loaded into the forging press 1 by the automatic loader 10 and a forging operation is performed.

When the hot forging material (m) heated from the material heating step (S192), which is the previous process, is injected, it is slid through the mobile chute (82) and seated on the material receiving device (72). Subsequently, the rotating device 70 is operated to rotate the rotating plate 74, and the material receiving device 72 also rotates together. In addition, the material receiving device 72 rotates about the hinge shaft 72 'at the same time as it rotates, and the forging material m therein is kept horizontal while the lower end thereof moves upward.

In addition, the vertical moving device 40 and the horizontal moving device 50 operate according to a signal input from the outside. That is, first, the body 30 moves downward along the vertical guide 44 by the operation of the vertical movement motor 42.

As the horizontal movement device 50 provided on the upper surface of the body 30 also moves downward at the same time as the body 30 moves downward, the loading grip 60 is seated on the material receiving device 72. To the position of the forged material (m). Then, the left grip 64 and the right grip 62 approach each other by the operation of the horizontal movable cylinder 54 to hold the forged material m seated on the material receiving device 72.

In addition, since the body 30 moves upward along the vertical guide 44, the loading grip 60 also moves upward. Next, the loading grip 60 moves to the right side (in FIG. 3) according to the operation of the horizontal moving cylinder 54 to move the forging material m into the forging press 1.

After the loading grip 60 is located inside the forging press 1, more specifically, in the center of the first mold 2, the left grip 64 and the right grip 62 are separated from each other. After the forging material is seated on the lower first mold 2 ", the loading grip 60 moves to the left side and returns to its original position.

As described above, when the forging material m is placed on the upper surface of the lower first mold 2 ", the slide 1" of the forging press 1 descends downwards, so that the upper first mold 2 'and the lower portion are lowered. The first mold 2 "comes into contact with each other. Therefore, the forging material m placed on the lower first mold 2" is bent. After the bending (Bending) as described above, the slide (1 ") of the forging press 1 is moved upwards to its original position.

 On the other hand, while the work is in progress by the forging press 1 as described above, a new forging material (m) is introduced into the material receiving opening 72 from the outside, it is set by the rotary device 70 (SETTING). . The forged material m is supplied to the forged press 1 by the loading grip 60 as described above.

The forging material m placed on the first mold 2 and primarily processed is gripped by the grip control device 160 of the automatic transfer machine 100, that is, by the first grip control device 160a. Transferred to the mold.

Next, the process of moving the forging material m by the operation of the automatic transfer machine 100 will be described with reference to FIGS. 4 to 9.

First, the operation method of the automatic transfer machine 100 will be described schematically. As shown in FIG. 9, a forward step S200 of advancing a pair of the transfer grips 180 spaced apart from each other, and the pair of transfer grips 180 are performed. G) holding the material while approaching each other (S210), the transfer grip 180 is moved upwards in a state of holding the forged material (m) (S220) and the transfer grip 180 Horizontal movement step (S230) to move horizontally in the state holding the forging material (m), and the downward movement step (S240) for moving the transport grip 180 to the lower side in the state of holding the forging material (m), and A loading step (S250) of placing the forged material (m) gripped by the transfer grip 180, a backward step (S260) of moving the pair of transfer grips 180 backward, and the pair of The transfer grip 180 is configured to return to the original position (S270) and the like.

Looking in more detail, the front and rear movement apparatus 150 is operated by a power applied from the outside. At this time, the transfer grip 180 is to maintain a distance from each other. That is, the transfer grip 180 is moved to the left side (in FIG. 7B) by the air cylinder 162 so that the pair of transfer grips 180 are positioned at the longest distance. In this state, the transfer grip 180 and the grip control device 160 move forward at the same time. [Advanced step; S200]

That is, the front-rear motor 154 is operated by an external power source to generate rotational power, and the rotational power is transmitted to the front-rear ball screw 152 by the front-rear connection belt 154 ". 152 is rotated so that the front and rear support nuts 156 move relative to each other so that the front and rear support plates 158 are moved forward (right side in Fig. 5). And the state in which the grip control device 160 is moved forward is shown in Figure 7a.

Next, looking at the process (holding step; S210) of the transfer grip 180 to hold the forging material (m) by the grip control device 160, by the operation of the air cylinder 162 the connection support ( 166 moves to the right (in FIG. 7B). In this case, the transfer grip 176 is pushed by the transfer link 176 is moved to the right to catch the forging material (m). At this time, the pair of transfer grips 180 are symmetrically moved horizontally to grip the material.

That is, since the transmission link 176 is rotated around the left end of the shaft, the first flow link 172a and the third flow link 172c rotate in the clockwise direction (in FIG. 7A) around the left end, The second flow link 172b and the fourth flow link 172d are rotated counterclockwise (in FIG. 7A) about the left end of the shaft. Therefore, the pair of transfer grips 180 are closer to each other to catch the outer circumferential surface of the forged material (m) in close contact with each other. [Gripping step; S210]

After the transfer grip 180 catches the forged material m, the transfer grip 180 is moved upward by the shank moving device 130. At this time, the rotary power generated from the up and down motor 132 is transmitted to the rotary nut 134 by the vertical connecting belt 132 ", the rotary nut housing 134 'surrounding the rotary nut 134 is It moves upward by the relative movement with the vertical ball screw 136.

Therefore, the support table 120 and the various components above the support table 120 coupled with the rotary nut housing 134 'are moved upward. In this case, the forged material (m) is moved to the upper side in the state fitted to a pair of the transfer grip 180. [Upward movement step; S220]

After the transfer grip 180 moves upward while holding the forged material m, the transfer grip 180 is horizontally moved by the left and right moving device 140. [Horizontal moving step; S230] That is, the left and right motor ( Rotating power generated from the 144 is transmitted to the left and right ball screw 142 by the left and right connecting belt 144 ", and the left and right ball screw 142 is rotated, the left and right support nuts 146 are left and right ball screw. It moves to the left or right by the relative movement with 142. Therefore, the left and right support plate 148 'and the upper part coupled to the left and right support nuts 146 and the upper parts simultaneously move laterally, so that the transfer grip 180 Forged material (m) caught in) will also move.

After the transfer grip 180 is moved by a distance set to the side, it is moved downward again. [Down movement step; S240] In this case, the shank moving device 130 is operated, and the upward movement step described above ( The operation in S220) is reversed. That is, the rotation directions of the upper and lower motors 132 and the rotation nut 134 are reversed.

When the downward movement step (S240) is completed, the forged material (m) is in a state seated in a mold (not shown) of the next process, the transfer grip 180 and the grip control device 160 is shown in Figure 7a Will be in the same state as Subsequently, the loading step S250 is performed.

The loading step S250 is opposite to the gripping step S210 described above. That is, the air cylinder 162 is operated in the state as shown in Figure 7a to pull the connection support 166 to the left. In this case, since the transmission link 176 is rotated around the left end of the shaft, the first flow link 172a and the third flow link 172c are rotated counterclockwise (in FIG. 7A) around the left end. The second flow link 172b and the fourth flow link 172d are rotated in a clockwise direction (in FIG. 7A) about an axis of the left end.

Accordingly, the pair of transfer grips 180 are separated from each other by the transfer grips 180 of the forged material m. [Loading step S250] The loading step S250 is thus performed. Is a process in which the pair of transfer grips 180 are horizontally symmetrically moved from each other to place the forged material m gripped on the mold or transfer conveyor 8 in the next process.

After loading the forging material (m) on the mold as described above, the reverse step (S260) is continued. The backward step S260 is opposite to the forward step S200 described above. That is, the direction of rotation of the front and rear motors 154 and the front and rear ball screws 152 is reversed, and the transfer grip 180 is moved to the rear side.

After the pair of transfer grips 180 are moved backwards, the pair of transfer grips 180 are returned to their original positions. [Returning Step; S270] The process is the reverse of the horizontal moving step (S230) described above. That is, the rotation directions of the left and right motors 144 and the left and right ball screws 142 become opposite to those of the horizontal moving step S230. After the return step (S270) is completed as described above, the forward step (S200) proceeds again and the above steps are continuously circulated.

On the other hand, as described above, the transfer grip 180 and the grip control device 160 is provided with three, respectively, such three transfer grip 180 and the grip control device 160 is composed of the assembly is operated at the same time. . Therefore, three forgings (m) are simultaneously transferred by one process.

In more detail, when the forging material (m) is loaded into the first mold (2) by the automatic loader 10, the forging press (1) is operated to process the forging material (m) In this case, the forging material (m) is loaded in the first mold (2), the second mold (4) and the third mold (6). That is, the forging material (m) of the unprocessed state is loaded in the first mold (2), and the forging material (processed primarily in the first mold (2) is loaded in the second mold ( m) is placed, and the forging material m sequentially processed in the first mold 2 and the second mold 4 is located in the third mold 6. Therefore, when the forging press 1 is operated, each forging material m placed on the first mold 2, the second mold 4 and the third mold 6 is simultaneously processed.

The three transfer grips 180 and the grip control device 160 are moved at the same time and three forged materials (m) placed on the first mold (2), the second mold (4) and the third mold (6). Are simultaneously moved to the right (in FIG. 1). That is, the first transfer grip 180a and the first grip control device 160a move the forging material m placed on the first mold 2 to the second mold 4, and the second transfer The grip 180b and the second grip control device 160b move the forging material m placed on the second mold 4 to the third mold 6, and the third transfer grip 180c and the second transfer grip 180c. The third grip control device 160c moves the forging material m placed on the third mold 6 to the transfer conveyor 8.

As such, after the forging material m is moved to the right side (in FIG. 1) by the automatic transfer machine 100, the first mold 2 is in an empty state, and at this time, the automatic loading machine 10 As a result, a new forging material m is loaded into the first mold 2.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.
