The clamping device 4 is arranged between the movable mould core 1 and the fixed mould core 2 and transversely clamps the workpiece when the fixed mould core 2 is pressed;

as shown in fig. 1, 2 and 3, the clamping device 4 includes a first chute 41 disposed on the top end surface of the cavity block 2, an L-shaped plate 42 slidably disposed on the first chute 41, a second chute 43 disposed on the horizontal section of the L-shaped plate 42, and a vertical plate 44 disposed on the second chute 43, wherein the vertical plate 44 and the vertical section of the L-shaped plate 42 are jointly provided with a connecting rod 45, the bottom wall of the cavity block 1 is provided with a hinge shaft 46, the hinge shaft 46 is hinged with a push-pull rod 47, and one end of the push-pull rod 47 is hinged with the side wall of the vertical plate 44; the top end surface of the fixed die core 2 is provided with a supporting component 5 for supporting a push-pull rod 47. The workpiece is placed on the fixed die core 2, and when the clamping device 4 is arranged, the driving cylinder 3 drives the movable die core 1 to punch, the push-pull rod 47 rotates under stress to enable the vertical plate 44 to drive the L-shaped plate 42 to move towards the middle of the fixed die core 2, so that the workpiece is clamped, the workpiece is kept stable when being machined, and the punching accuracy is ensured. After the punching is finished, the driving cylinder 3 drives the movable die core 1 to reset, at the moment, the push-pull rod 47 is stressed to rotate to drive the L-shaped plate 42 to move towards the direction far away from the middle part of the fixed die core 2, and the clamping of the workpiece is released, so that the workpiece is easily taken out. The clamping device 4 is automatically driven to clamp the workpiece in the process of stamping the movable die core 1, so that the integration of automatic stamping and clamping is realized, the participation of manpower is reduced, and the stamping efficiency and the forming rate are improved.

Threaded holes 441 are formed in the positions, with the same height, of the vertical plate 44 and the L-shaped plate 42, and the connecting rod 45 is a threaded rod 451 in threaded connection with the threaded holes 441. Through the arrangement of the threaded rod 451 and the threaded hole 441, the vertical plate 44 can be driven to slide along the second sliding groove 43 by rotating the threaded rod 451, so that the distance between the L-shaped plate 42 and the vertical plate 44 can be adjusted, and the use requirements of workpieces with different specifications can be met. The threaded rod 451 transmits force so that the riser 44 and the L-shaped plate 42 move together under the action of the push-pull rod 47.

The threaded rod 451 is provided with lock nuts 452 respectively located on both sides of the L-shaped plate 42. Through setting up lock nut 452, rotatory threaded rod 451 adjusts the completion back, and rotatory lock nut 452 makes lock nut 452's lateral wall and the vertical section of L template 42 hug closely to the rotation of restriction threaded rod 451, the stability of power transmission between reinforcing threaded rod 451 and the L template 42 has also increased the lifting surface area of the screw thread on the threaded rod 451 simultaneously, prevents that the screw thread on the threaded rod 451 of centre gripping in-process from receiving the too big thread fracture that leads to of yawing force.

The supporting component 5 includes a fixing block 51 welded on the top end face of the fixed mold core 2, the fixing block 51 is connected with a supporting rod 52 through a bearing, the push-pull rod 47 is provided with a third sliding groove 471 along the length direction thereof, one end of the supporting rod 52 is provided with a connecting shaft 53, part of the connecting shaft 53 protrudes out of the supporting rod 52, and the protruding part of the connecting shaft 53 is connected with the third sliding groove 471 in a sliding manner. When the push-pull rod 47 rotates, the force is transmitted through the connecting shaft 53, and the support rod 52 is driven to rotate together. By providing the support rod 52 to support the middle portion of the push-pull rod 47, the possibility of the push-pull rod 47 breaking off from the middle portion during rotation can be effectively reduced.

And a torsion spring 6 is arranged on the side wall of the fixing block 51 close to one end of the L-shaped plate 42, and one end of the torsion spring 6 is abutted to the support rod 52. When the clamping device 4 clamps the workpiece, the torsion spring 6 is stressed and bent to accumulate elastic potential energy, and when the driving cylinder 3 drives the movable die core 1 to reset, the torsion spring 6 releases the elastic potential energy to push the support rod 52 to rotate, so that the effect of assisting the reset can be achieved, and the load of the driving cylinder 3 in the reciprocating process is balanced.

Two spring push rods 7 are installed at the bottom end of the movable die core 1, and a stamping plate 71 is installed at the end parts of the two spring push rods 7 together. The press plate 71 clamps the workpiece and performs press forming on the workpiece when the moving core 1 is pressed.

The working principle is as follows: through setting up clamping device 4, when driving actuating cylinder 3 and drive movable mould benevolence 1 punching press, push-and-pull rod 47 atress rotates and makes riser 44 atress, drives L template 42 through threaded rod 451 behind the riser 44 atress and moves to the middle part of fixed mould benevolence 2, carries out the centre gripping to the work piece, and punching press plate 71 presss from both sides tight work piece and carries out stamping forming to the work piece simultaneously. After the punching is finished, the driving cylinder 3 drives the movable die core 1 to reset, at the moment, the push-pull rod 47 is stressed to rotate to drive the L-shaped plate 42 to move towards the direction far away from the middle part of the fixed die core 2, the torsion spring 6 releases elastic potential energy to help push the support rod 52 to rotate, the clamping of the workpiece is loosened, and the workpiece is conveniently taken out.
