[0002] Gear forging is a transmission mechanical device. The rim has teeth that can continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. In the late 19th century, the principle of generating tooth cutting and the special machine tool and cutter using this principle were developed. With the development of production, the smoothness of gear operation is valued.

[0003] When the forging mechanism processes the gear blank, the gear blank needs to be forged in all directions and continuously.

[0004] However, the existing forging die for gear steel forging production and processing can easily affect the rotation of the gear blank after the die fixes the gear blank, so that the forging mechanism can only forge the gear blank in a single direction, which limits the forging effect of the forging mechanism, and thus the use effect of the die is not ideal. SUMMARY

[0007] The beneficial effects of the present application are as follows:

[0008] The gear steel forging production and processing forging die is better, and the gear blank can be fixed, the gear blank is prevented from rotating during forging and affecting the forging effect, after the gear plate rotates, the rotation of the gear plate acts on the linkage touch plate to reversely rotate the movable rotating plate, so that the end of the limiting block is separated from the gear blank, the friction force on the gear blank is reduced, the gear plate can normally drive the gear blank to rotate after rotating, and the forging mechanism can continuously stamp and forge the gear blank.

[0009] On the basis of the above technical scheme, the application can also be improved as follows.

[0013] The beneficial effect of the above further scheme is that the rotation of the second servo motor can change the distance between the multi-directional screw rod and the arc-shaped supporting block, so that the distance is adapted to the inner diameter of the gear blank, thereby enabling the four arc-shaped supporting blocks to simultaneously abut against the inner circumferential wall of the gear blank to achieve the effect of supporting the gear blank.

[0026] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , in order to further make the mold have adjustable effect, the sliding groove 101 is opened in the bottom plate 1, the inner peripheral wall of the sliding groove 101 is fixedly connected with the servo motor one 102, the output shaft end of the servo motor one 102 is fixedly connected with the one-way screw rod 103, the outer peripheral wall of the one-way screw rod 103 is threadedly connected with the U-shaped sliding plate 104, the end of the U-shaped sliding plate 104 is fixedly connected with the sliding clamp plate 3, the middle of the sliding clamp plate 3 is embeddedly connected with the servo motor two 301, the sliding groove 101 is opened in the bottom plate 1, and the servo motor one 102 is arranged on the inner peripheral wall of the sliding groove 101, and the output shaft end of the servo motor one 102 is fixed with the one-way screw rod 103, so that the servo motor one 102 can drive the one-way screw rod 103 to rotate after the servo motor one 102 is operated, and since the one-way screw rod 103 is threadedly connected with the U-shaped sliding plate 104 and the U-shaped sliding plate 104 cannot rotate by itself, the U-shaped sliding plate 104 can slide along the one-way screw rod 103, thereby driving the sliding clamp plate 3 to move on the top of the bottom plate 1 and changing the distance between the sliding clamp plate 3 and the fixed clamp 2, so that the user can drive the gear blank into the cavity 201 when the gear blank is sleeved on the outer peripheral wall of the supporting steel pipe 4, and after continuous movement, the end of the supporting steel pipe 4 can be clamped on the inner peripheral wall of the positioning groove 203, so that the fixed clamp 2 can support the supporting steel pipe 4 together with the sliding clamp plate 3, so as to ensure that the supporting steel pipe 4 can bear the pressure when the forging mechanism is forging the gear blank, and through this function, the user can conveniently put the gear blank into the mold and take it out from the mold after forging.

[0027] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3As shown, to further improve the mold's fixing effect on the gear blank, a supporting steel pipe 4 is fixedly connected to one side of the sliding clamp 3. An inner cavity 401 is formed inside the supporting steel pipe 4. A multi-directional lead screw 402 is rotatably connected to the inner peripheral wall of the inner cavity 401. The end of the multi-directional lead screw 402 is fixedly connected to the end of the output shaft of the servo motor 301. Two partition blocks 403 are fixedly connected to the outer peripheral wall of the multi-directional lead screw 402. Two lead screw collars 404 are symmetrically arranged on both sides of each partition block 403. All four lead screw collars 404 are threadedly connected to the multi-directional lead screw 402. Each lead screw collar 404 has four connecting rods 405 symmetrically arranged on its outer peripheral wall. One end of each connecting rod 405 is hinged to the lead screw collar 404, and the other end of each connecting rod 405 is hinged to an arc-shaped support block 406. An inner cavity 401 is formed inside the support steel pipe 4, and a multi-directional lead screw 402 is arranged on the inner peripheral wall of the inner cavity 401. The end of the multi-directional lead screw 402 is fixed to the output shaft of the second servo motor 301, so that the second servo motor 301 can drive the multi-directional lead screw 402 to rotate. Then, two partition blocks 403 hold the multi-directional lead screw 402 in place. The texture is divided into three segments, with adjacent segments having opposite textures. Based on this, two sets of lead screw collars 404 and connecting rods 405 are set on each side of the two dividing blocks 403. The two sets of lead screw collars 404 and connecting rods 405 simultaneously form a deformable parallelogram, which is connected to the arc-shaped support block 406 at the intersection of the two connecting rods 405. This increases the support effect of the multi-directional lead screw 402 on the arc-shaped support block 406, and allows the spacing between the two lead screw collars 404 in the same set to change after the multi-directional lead screw 402 rotates. The distance between the multi-directional lead screw 402 and the arc-shaped support block 406 is further changed so that this distance is adapted to the inner diameter of the gear blank. This allows the four arc-shaped support blocks 406 to simultaneously abut against the inner circumferential wall of the gear blank, thereby achieving the effect of supporting the gear blank. Based on this, the user can control the servo motor 301 to rotate according to the inner diameter of the gear blank, thereby changing the distance between the four arc-shaped support blocks 406 to achieve the effect of fixing gear blanks with different inner diameters, and the fixing effect of the gear blank is better.

[0028] The specific working process of this invention is as follows:

[0029] (1) Move the sliding clamp 3

[0030] First, the servo motor 102 driven by electric power drives the one-way screw 103 to rotate, thereby driving the U-shaped slide plate 104 and the sliding clamp 3 to move along the one-way screw 103, so as to change the distance between the sliding clamp 3 and the fixed clamp 2.

[0031] (2) Place the gear blank in

[0032] Then, the distance between the sliding clamp 3 and the fixed clamp 2 is adjusted, and when the distance between the support steel pipe 4 and the fixed clamp 2 is greater than the width of the gear blank, the user can put the gear blank into the mold and wrap it around the outer peripheral wall of the support steel pipe 4, and then fold the sliding clamp 3 and the fixed clamp 2.

[0033] (3) Adjust the distance between the four arc-shaped support blocks 406

[0034] Then, the servo motor 301 is used as the power to drive the movement of the screw sleeve 404, so as to change the distance between the four arc-shaped support blocks 406, so as to adapt to the inner diameter size of the gear blank, so as to achieve the effect of fixing and supporting the gear blank.

[0035] (4) Drive the gear blank to rotate

[0036] Finally, the gear plate 204 is in contact with the gear blank, and in the process of contact, the limiting block 504 indirectly positions the gear blank through the action of the linkage contact plate 503, and at the same time, the gear plate 204 is driven by the motor 206 to indirectly make the gear blank rotate, and when rotating, the limiting block 504 is separated to allow the forging mechanism to pass through the stamping hole 202 to forge and stamp the next position of the gear blank.
