The clamp 22 and the clamp 23 are separated from each other and can be released from the forged parts that are cooperatively clamped in the first state.

The continuous rotation of the driving shaft 63 can drive the first cam 61 and the second cam 62 to use the first flat wheel surface 611 and the second flat wheel surface 621 for the first roller 512 and the second roller, respectively. Sub 522 rolled in.

The first roller 512 abuts against the first flat wheel surface 611, which drives the second base arm 521 to pivot forward with the support shaft unit 3 as an axis, and passes the first arm portion 515 through the first A linking member 53 (refer to FIG. 4) pushes the first end portion 412 of the swing arm 41 upward, so that the swing arm 41 pivots about the pivot unit 3 as an axis, and drives each pivot arm The two pivotal joints of 422 are pivoted, and the connecting arm 421 is driven to cause the clamp 22 to be clamped forward with the clip 23, so that the embodiment returns to the first state.

In this embodiment, when changing between the first state and the second state, it will withstand the impact force generated when the clamp 22 and the clamp 23 are bonded together, and when the forged part is punched by the punching device. The generated forging force, but in this embodiment, the pivot arm group 42 can reduce the forces on the first arm group 51 and the second arm group 52, so that the first arm group 51 and the second arm group 51 The arm group 52 is not easily deformed, effectively extending the service life of the components of the first arm group 51 and the second arm group 52, and solving the clamping of the clamp unit 22 and the clamp member 23 due to the stress deformation of the pivot unit 3 The problem of reduced accuracy. In addition, this embodiment can also reduce the force experienced by the first roller 512 and the second roller 522, and increase the service life of the first roller 512 and the second roller 522.

In this embodiment, in the first state, the linkage unit 5 is mainly based on the first arm portion 515 of the first arm group 51 and is pushed by the first flat wheel surface 611 through the first roller 512. The first base arm 511 can abut against the swing arm 41, and in the second state, the linkage unit 5 mainly uses the second arm portion 525 of the second arm group 52 to pass through the second roller 522 is pressed by the cam surface 622, so that the second base arm 521 can indirectly penetrate the swing arm 41 through the first extension portion 514 of the first base arm 511. Since the first arm group 51 and the second arm group 52 are subjected to the action of the cam unit 6 in turn, the force from the cam unit 6 can be dispersed, and the first base arm 511 and the first roller 512 can be improved. , The service life of the second base arm 521 and the second roller 522, and reduce the damage caused by the damage of the first base arm 511, the first roller 512, the second base arm 521 and the second roller 522 The probability that the machine needs to be stopped and replaced, and improve the production efficiency of the machine.

The elastic member 57 can press the first extension portion 514 of the first base arm 511 upward, and can press the second extension portion 524 of the second base arm 521 downward, so that the first base arm The first arm portion 515 of 511 and the second arm portion 525 of the second base arm 521 elastically approach each other. This design can ensure that the first roller 512 and the second roller 522 can still abut the cam unit 6 when there is an error in the manufacture or installation of the component. The elastic member 57 also has the effect of absorbing the stress received by the first arm group 51 and the second arm group 52. In addition, when the installation is not ideal or it is used to produce different forged parts, and there is a need to adjust the distance or clamping state of the clamp 22 and the clamp 23, the user can adjust the first linkage 53 by screwing With the second linkage member 54, the relative positional relationship between the first base arm 511 and the swing arm 41 is changed, and the pivoting state of the swing arm 41 is changed.

To sum up, the effect of the driving device of the forging parts processing machine of the present invention is that the stress on the fulcrum unit 3 is reduced through the linkage unit 5 and the pivot arm group 42 and the The service life can solve the problem of reduced clamping accuracy, reduce the possibility of replacement due to damaged parts, and improve the production efficiency of the machine.
