[0018] S2. Start the stamping cylinder to drive the thrust plate to push the magnetic block into the support components, and the support vertical plate clamps the metal plate to wrap the magnetic block;

[0019] S3. In step S2, when the support plate clamps the metal sheet to wrap the magnetic block, the bending push plate pushes the cross-shaped metal sheet to bend inwardly of the magnetic block, and contacts the magnetic block in advance to maintain pre-tightening;

[0020] S4. Continue to push the thrust plate to pass the magnetic block wrapped by the cross-shaped metal sheet through the material passing ring, and then take it out to complete the operation.

[0021] The beneficial effects of the present invention are as follows: the present invention is a stamping die and a stamping method for producing and processing magnetic blocks that utilizes a stamping device to effectively assist in fixing the magnetic blocks and solve the problem of rapid disassembly of the magnetic blocks. The specific implementation methods are as follows:

[0022] The operator first places the cross-shaped metal sheet on the top of the hinge mechanism, and the magnet block, collectively called the magnetic block, is placed on the sheet, and then the stamping cylinder is started to slowly drop. During the falling process, the extension rod of the stamping cylinder contacts the friction wheel, driving the friction wheel to rotate the worm, and the toothless gear engaged by the worm rotates, thereby driving the rotating threaded groove rod to rotate. At the same time, after the rotating threaded groove rod rotates, it drives the push-correction constraint plate on the rectangular groove plate to fall. After the sheet is guided to between the bending push plates by the push-material bevel, the stamping cylinder continues to drop. At the same time, the worm also rotates the toothless gear to the vicinity of the cavity, and no longer continues to push the rectangular groove plate to fall. The thrust plate on the stamping cylinder contacts the magnetic block. At the same time, the pointed sliding block in the guide block on the thrust plate constrains the magnetic block to the center of the sheet for positioning. After completion, the magnetic block continues to be squeezed through the thrust plate, and the magnetic block pushes the sheet through the hinge mechanism When there is a gap, the plate pushes the guide top plate to flip the push plate along the circumferential chamfer along the guiding action of the circular plate supported by the circumferential groove, and at the same time bends the plate to fit the surface of the magnetic block. When it is flipped to a certain position, the push rod contacts the toggle block, and the push rod rotates in the movable groove along the guiding action of the rotating connecting rod. At the same time, the guide cross bar also slides between the guide grooves, pushing the push plate toward the center of the hinge mechanism. At the same time, the bending push plate pushes the plate to bend. Since the metal plate is tough, it will not break after bending, resulting in the bending clamping of the four sides of the magnetic block except the bottom surface, producing a similar clamping effect. The magnetic block is fixed by the elastic force of the plate and can be easily disassembled. It is only necessary to resist the elastic force of the plate and then take out the magnetic block; at the same time, in the process of bending the plate, the plate will contact the pointed sliding block to resist the thrust spring to move upward and then break away from the clamping of the pointed sliding block on the magnetic block.

[0023] After completing the above operations, continue to push the thrust plate downward, push out the material passing ring, until the placement plate contacts the contact vertical plate, and is guided by the guide bevel, driving the contact vertical plate to resist the torsion spring and flip the extended toggle rod along the guide of the rotating nail, so that the unloading toggle rod contacts the wrapped magnetic block and pushes the wrapped magnetic block out. During the pushing process, the placement plate is tilted by the connection effect of the connecting rod and the rotating rod, expanding the gap between it and the thrust plate, and assisting the wrapped magnetic block to fall better.

[0024] At the same time, since the guide top plate and the circumferential groove supporting circular plate are connected by connecting the transverse groove and the connecting buckles between the circumferential grooves on the circumferential groove supporting circular plate, during the rotation of the guide top plate, the friction force of the plate will not cause the guide top plate to separate from the circumferential groove supporting circular plate.

[0025] After wrapping, the magnetic block can be used to position the welding plate. Due to the metal isolation, the heat generated by welding is conducted through the metal and has basically no effect on the magnetic force of the magnetic block. At the same time, the magnetic block can be removed by resisting the toughness of the plate.

[0026] The device has a simple structure and can effectively solve the problem of magnetic influence when the magnetic block is fixed by wrapping the magnetic block with metal sheet through a stamping structure. At the same time, the magnetic block can be quickly removed, which has good practicality and economy and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Advantageously, a punching method for producing and processing a magnetic block is also included, and the specific implementation steps are as follows:

[0054] S1. Place the cross-shaped metal sheet on top of the placement plate 212 and place the magnetic block on the surface of the sheet;

[0055] S2. Start the stamping cylinder 31 to drive the thrust plate 32 to push the magnetic block into the support assembly, and the support plate 41 clamps the metal sheet to wrap the magnetic block;

[0056] S3. In step S2, during the process of the support plate 41 clamping the metal sheet to wrap the magnetic block, the bending push plate 44 pushes the cross-shaped metal sheet to bend into the magnetic block, contacting the magnetic block in advance to maintain pre-tightening;

[0057] S4. Continue to push the thrust plate 32 to pass the magnetic block wrapped by the cross-shaped metal plate through the material passing ring 141, and then take it out to complete the operation.

[0058] Working principle of the present invention:

[0059] The operator first places the cross-shaped metal sheet on the hinge mechanism 4, and the magnet block, collectively referred to as the magnet block, is placed on the sheet, and then starts the stamping cylinder 31 to slowly drop. During the falling process, the extension rod of the stamping cylinder 31 contacts the friction wheel 53, driving the friction wheel 53 to rotate the worm 531, and the toothless gear 55 engaged with the worm 531 rotates, thereby driving the rotating thread groove rod 511 to rotate. At the same time, after the rotating thread groove rod 511 rotates, it drives the push-up constraint plate 52 on the rectangular groove plate 51. The plate is guided to the bending push plate 44 by the pusher bevel 521, and the punching cylinder 31 is continued to fall. At the same time, the worm 531 also rotates the toothless gear 55 to the vicinity of the cavity, and no longer pushes the rectangular slot plate 51 to fall. The thrust plate 32 on the punching cylinder 31 contacts the magnetic block. At the same time, the pointed sliding block 34 in the guide block 33 on the thrust plate 32 constrains the magnetic block to the center of the plate for positioning. After completion, the magnetic block is squeezed by the thrust plate 32. When the magnetic block pushes the plate through the gap of the hinge mechanism 4, The plate pushes the guide top plate 42 to flip the push plate 43 along the circumferential chamfer 411 along the guiding effect of the circumferential groove supporting circular plate 451, and at the same time bends the plate to fit the surface of the magnetic block. When flipped to a certain position, the push rod 4221 contacts the toggle block 412, and the push rod 4221 rotates in the movable groove 422 along the guiding effect of the rotating connecting rod 4222. At the same time, the guide cross bar 431 also slides between the guide grooves 421, and one end of the push rod 4221 pushes the push plate 43 toward the hinge mechanism in the push groove 432. The structure 4 moves closer to the center direction, and the bending push plate 44 pushes the plate to bend. Since the metal plate is tough, it will not break after bending, resulting in the four sides of the magnetic block except the bottom surface being bent and clamped, producing a similar grasping effect. The magnetic block is fixed by the elastic force of the plate and can be easily disassembled. You only need to resist the elastic force of the plate and then take out the magnetic block; at the same time, in the process of bending the plate, the plate will contact the pointed sliding block 34 to resist the push spring 36 to move upward and then break away from the clamping of the pointed sliding block 34 on the magnetic block.

[0060] After completing the above operations, continue to push the thrust plate 32 downward, push out the material passing ring 141, until the placement plate 212 contacts the contact vertical plate 24, and is guided by the guide bevel 241, driving the contact vertical plate 24 to resist the torsion spring 252 and flip the extended toggle rod 26 along the guide of the rotating nail 251, so that the unloading toggle rod 261 contacts the wrapped magnetic block and pushes the wrapped magnetic block out. During the pushing process, the placement plate 212 is tilted by the connection effect of the connecting rod 2121 and the rotating rod 213, expanding the gap between the thrust plate 32 and the wrapped magnetic block to help it fall better. After the magnetic block falls, the reset spring 23 pushes the support top rod 21 to reset.

[0061] At the same time, since the guide top plate 42 and the circumferential groove supporting circular plate 451 are connected by connecting the transverse groove 423 and the connecting buckle 46 between the circumferential groove on the circumferential groove supporting circular plate 451, during the rotation of the guide top plate 42, the friction force of the plate will not cause the guide top plate 42 to separate from the circumferential groove supporting circular plate 451.

[0062] After wrapping, the magnetic block can be used to position the welding plate. Due to the metal isolation, the heat generated by welding is conducted through the metal and has basically no effect on the magnetic force of the magnetic block. At the same time, the magnetic block can be removed by resisting the toughness of the plate.
