Description

Technical Field

[0001] The utility model belongs to the technical field of punching machine demoulding devices, in particular to an automatic punching machine demoulding device with which workpieces can be easily taken out. Background Art

[0002] Stamping is a metal processing technology, also known as sheet metal forming. The stamping operation of the workpiece requires the use of a stamping machine and a stamping die. In common stamping operations, the stamping machine drives the upper die and the lower die to squeeze the workpiece to complete the stamping and forming operation of the workpiece. Then the operator manually demolds and removes the stamped workpiece. However, after the workpiece is stamped, due to the punching force, the workpiece will be engaged with the lower die, making it impossible to automatically demold the workpiece and inconvenient to remove the workpiece. The operator often needs to use a certain amount of force to complete the workpiece removal operation, which consumes extra physical strength. Long-term operation will make the operator more tired, which is not conducive to production and processing.

[0003] Secondly, when the operator uses external force to remove the workpiece, due to the problem of force application, there may be a certain amount of backward inertia at the moment of removal, which may cause the operator to fall and may be scratched by the workpiece during the removal process.

[0004] In summary, after stamping is completed, the workpiece is not easy to be removed from the die and there are some problems in use, so it is hoped that a new structure is proposed to solve the above technical problems. Summary of the invention

[0011] A damping telescopic rod 2 is provided on the inner side of the demoulding auxiliary spring. The damping telescopic rod 1 and the damping telescopic rod 2 are concentrically located on the same vertical line. During the stamping process, the workpiece applies pressure to the automatic demoulding mechanism to compress the demoulding auxiliary spring. After the stamping is completed, the external force disappears and the demoulding auxiliary spring rebounds, lifting the top ring frame upward, so that it automatically demoulds the workpiece, thereby facilitating the removal of the workpiece.
