In some embodiments, the box 11 is a detachable cavity structure to facilitate disassembly and assembly for maintenance.

As shown in fig. 5, in some embodiments, a sliding hole 121 is formed in the center of the back shaft 12 along the axial direction of the back shaft 12, the sliding hole 121 is used for matching the collet 13 to make a linear reciprocating motion in the back shaft 12, the sliding hole 121 penetrates through two end faces of the back shaft 12, a first sealing member 122 is mounted on a side wall of the sliding hole 121 on the back shaft 12, the first sealing member 122 is used for closing a gap between the collet 13 and the sliding hole 121, and a matching surface 123 for forcing the collet 13 to close is formed on the back shaft 12 corresponding to the collet 13.

Therefore, according to the above technical solution, when the collet 13 is forced to slide on the back shaft 12 and the pressing surface 132 abuts against the mating surface 123 on the back shaft 12, due to the pressing of the pressing surface 132, a pressing force in a substantially radial direction of the collet 13 is generated, so that the clamping ends of the collet 13 are forced to deform inward and close to clamp the workpiece. The outer side wall of the collet 13 abuts against the first seal 122 on the back shaft 12, so that a seal is formed between the collet 13 and the back shaft 12 to block the flow of foreign substances from the gap between the collet 13 and the back shaft 12.

As shown in fig. 4, the back shaft mechanism of the present invention further includes a piston 14, a push-pull member 15, a switching member 16 and a joint 18, which are slidably disposed in a plug cavity 131 of the collet 13, wherein the joint 18 is used for introducing a high-pressure medium into the plug cavity 131 of the collet 13 to slide the piston 14 in the collet 13, so as to eject the workpiece from the collet 13 when the piston 14 impacts the workpiece, thereby completing the blanking.

Through the scheme, when the output member 171 on the first driver 17 rotates, the conversion member 16 is driven to rotate, the conversion member 16 rotates to enable the push-pull member 15 to be in threaded connection and matching with the conversion member 16, so that the torsional force output by the first driver 17 is converted into a force enabling the conversion member 16 to slide along the axial direction, the collet 13 tends to be closed when the push-pull member 15 moves away from the collet 13, the collet 13 tends to be opened when the push-pull member 15 moves close to the collet 13, and the movement amount of the collet 13 is conveniently and accurately controlled through the first driver 17 through a similar screw rod mechanism formed by matching the push-pull member 15 with the conversion member 16.
