The second hinge seat 405 moves downward and pushes the wedge block 401 to move through the hinged action of the hinge rod 406 and the first hinge seat 402. The wedge block 401 is further driven by the guide block 40 The sliding connection between the wedge block 401 and the guide rod 409 can further ensure the sliding stability of the wedge block 401. When the wedge block 401 moves, the top of the L-shaped strip 303 is pushed up by the wedge force, so that the L-shaped strip 303 is turned over along the connection position between the torsion rod 302 and the torsion seat 301, so that the four L-shaped strips 303 push the four L-shaped strips 303 together with the centering plate 308 to move toward the middle, the first spring 309 is stretched and stored, and the four centering plates 308 move toward the middle just to align with the first spring 309 placed on the first spring 309.

[0040] If it is necessary to center workpieces of other specifications, it is necessary to rotate the crank handle 407 to drive the threaded rod 403 to rotate, so that the internal thread block 404 moves up and down under the cooperation of the thread of the threaded rod 403, and the internal thread block 404 moves up and down to drive the second hinge seat 405 to move together, and further drive the wedge block 401 to move along the top of the cross 2 through the connection between the hinge rod 406 and the first hinge seat 402, and adjust the initial position of the wedge block 401, so as to realize the adjustment of the moving stroke of the four centering plates 308, which is convenient for stamping workpieces of different specifications and improves the universality of the device.

[0041] Furthermore, guide rods 409 are provided on both sides of the wedge block 401, and fixing seats 408 are fixedly installed at both ends of the guide rods 409.

[0042] Furthermore, a second spring 4011 is sleeved on the periphery of the guide rod 409, and the second spring 4011 is fixedly installed between one of the fixed seats 408 and the guide block 4010. When the hinge rod 406 pushes the first hinge seat 402 and the wedge block 401 to move, it will drive the guide block 4010 to slide along the outer wall of the guide rod 409, thereby compressing the second spring 4011 to cause rebound elasticity. After the stamping is completed, the double-rod cylinder 5 is started so that the output rod of the double-rod cylinder 5 drives the pressure head 501 to move upward. At the same time, the output rod of the double-rod cylinder 5 will also drive the threaded rod 403 and the internal thread block 404 to move upward. The movement of the internal thread block 404 drives the second hinge seat 405 to move.

The wedge block 401 is also affected by the sliding connection between the guide block 4010 and the guide rod 409. , which can further ensure the sliding stability of the wedge block 401. When the wedge block 401 moves, the top of the L-shaped strip 303 is pushed up by the wedge force, so that the L-shaped strip 303 is turned over along the connection position between the torsion rod 302 and the torsion seat 301, so that the four L-shaped strips 303 push the four L-shaped strips 303 together with the centering plate 308 to move toward the middle, the first spring 309 is stretched and stored, and the four centering plates 308 move toward the middle to just exert a centering effect on the workpiece placed on the top of the placement plate 6, so that there is no need for manual intervention in the position of the workpiece, which improves the accuracy and convenience of stamping;

[0045] After the stamping is completed, the double-rod cylinder 5 is started, so that the output rod of the double-rod cylinder 5 drives the pressure head 501 to move upward. At the same time, the output rod of the double-rod cylinder 5 will also drive the threaded rod 403 and the internal thread block 404 to move upward. The movement of the internal thread block 404 drives the second hinge seat 405 to move.

The first spring 309 is elastically released, pushing the centering plate 308 to move in the opposite direction. The movement of the centering plate 308 drives the elastic telescopic rod 306 and the pin 307 to move together. Further, under the connection between the pin 307 and the strip groove 305, the L-shaped strip 303 is driven to rotate in the opposite direction along the connection position between the torsion rod 302 and the torsion seat 301, so that the four centering plates 308 release the centering effect on the workpiece, which can facilitate the stamped workpiece to be removed from the top of the placement plate 6;

[0046] If it is necessary to center workpieces of other specifications, it is necessary to rotate the crank handle 407 to drive the threaded rod 403 to rotate, so that the internal thread block 404 moves up and down under the cooperation of the thread of the threaded rod 403, and the internal thread block 404 moves up and down to drive the second hinge seat 405 to move together, and further drive the wedge block 401 to move along the top of the cross 2 through the connection between the hinge rod 406 and the first hinge seat 402, and adjust the initial position of the wedge block 401, so as to realize the adjustment of the moving stroke of the four centering plates 308, which is convenient for stamping workpieces of different specifications and improves the universality of the device.
