Through energizing electromagnet 21, fixedly connected's sheetmetal 20 on the threaded rod 22, under the effect of attraction, will rotate a bit angle, because threaded rod 22 and movable block 13 threaded connection, after threaded rod 22 rotated, threaded rod 22 also can horizontal migration a bit distance, the rotating block 14 of rotating connection on the threaded rod 22, also can be horizontal migration simultaneously, thereby make behind the first splint 23 horizontal migration, with the surface contact of stamping workpiece inseparabler, after electromagnet 21 cuts off the power supply, because torsion spring 15 both ends respectively with threaded rod 22, and movable block 13 fixed connection, under torsion spring 15's spring action, just can make threaded rod 22 reverse emergence rotation.

After the threaded rod 22 rotates reversely, the threaded rod 22 also moves horizontally for a certain distance, and the first clamping plate 23 fixedly connected to the rotating block 14 also moves along with the threaded rod, so that the steel balls 24 on the mounting block just pass through the through holes 5 in the first clamping plate 23, the surfaces of the steel balls 24 are in surface contact with the surface of the stamping part, and the stamping part is more convenient to rotate.

Under the action of the hydraulic cylinder 3 on the machine body 1, the transverse plate 7 fixedly connected with the lower end moves downwards, the first clamping plate 23 and the second clamping plate 25 are lowered to the height matched with the stamping part, the hydraulic rod 8 moves upwards relative to the transverse plate 7, the hydraulic rod 8 slides relative to the fixed block 4, the rack plate 9 fixedly connected with the hydraulic rod 8 rotates the gear 26 meshed with the gear 26 in the process of moving upwards, the rotating shaft 27 fixedly connected with the gear 26 rotates under the transmission action of the gear 26, the first pulley fixedly connected with the rotating shaft 27 rotates simultaneously, the first pulley is connected with the second pulley 6 through the transmission belt 17, the bidirectional screw rod 16 rotates under the transmission action of the second pulley 6, the two moving blocks 13 in threaded connection are arranged on the bidirectional screw rod 16, will move towards each other;

because the sliding rod 19 slides in the sliding groove, the rotation of the moving block 13 is limited, so that the rotating block 14 which is connected with the two threaded rods 22 in a rotating way moves horizontally in opposite directions, the two first clamping plates 23 can clamp and fix the stamping part in the process of moving in opposite directions, then the electromagnet 21 is electrified, the metal sheet 20 rotates under the action of attraction force, the threaded rod 22 which is fixedly connected with the metal sheet 20 rotates simultaneously, because the threaded rod 22 is connected with the moving block 13 in a threaded way, the threaded rod 22 can also move horizontally for a certain distance in the rotating process, so that the first clamping plate 23 which is fixedly connected with the rotating block 14 can be more tightly attached to the surface of the stamping part after moving along with the threaded rod, the clamping effect on the stamping part is better, and meanwhile, in the process that the hydraulic rod 8 moves upwards, because one end of the hinge rod 10 is hinged with the hydraulic rod 8, the other end of the first clamping plate is hinged with the limiting rod 11, the included angle between the two hinged rods 10 is reduced, and the two limiting rods 11 move oppositely, so that the two second clamping plates 25 move oppositely, and the steel balls 24 on the second clamping plates 25 are in contact with the surfaces of the first clamping plates 23;

when the shearing position of the stamping part needs to be adjusted, or the notch is machined, by disconnecting the electricity of the electromagnet 21, because one end of the torsion spring 15 is fixedly connected with the moving block 13, and the other end of the torsion spring is fixedly connected with the moving block 13, under the action of the elasticity of the torsion spring 15, the threaded rod 22 can rotate reversely for a certain angle, at the moment, the first clamping plate 23 on the rotating block 14 moves reversely for a certain distance, so that the steel balls 24 on the second clamping plate 25 just pass through the through holes 5 on the first clamping plate 23, the surface of the cylindrical stamping part is contacted with the steel balls 24, the stamping part can be conveniently rotated to adjust the position of the shearing stamping part, or the notch is machined in the next step by rotating, after the adjustment, the shearing blade 2 can shear the stamping part, because the stamping part has better clamping and fixing effects, when the stamping part is sheared, the stamping part can not move, the bending phenomenon at the shearing opening can not occur, and the subsequent bending phenomenon of the cut can not be processed, so that the stamping part can be smoothly processed in the next step, and the processing efficiency of the stamping part is improved.

Example two

Referring to fig. 6-7, a fixing rod 28 is fixedly installed on the moving block 13 in a transverse direction, a round hole for connecting the fixing rod 28 is formed in the rotating block 14, the fixing rod 28 is used for limiting the rotation of the rotating block 14, when the punching part is sheared by the shearing blade 2, the first clamping plate 23 tightly attached to the punching part vibrates, because the fixing rod 28 is transversely arranged, one end of the fixing rod 28 is fixedly connected with the moving block 13, and the round hole for connecting the fixing rod 28 is formed in the rotating block 14, when the rotating block 14 needs to horizontally move, the rotating block 14 slides relative to the fixing rod 28, under the limiting action of the fixing rod 28, when the first clamping plate 23 vibrates, the rotating block 14 fixedly connected to the first clamping plate 23 does not rotate relative to the threaded rod 22, so that the first clamping plate 23 does not deflect, and the first clamping plate 23 fixes the punching part, and is more stable, so that the fixing effect on the stamping part is better.
