In order to solve the problem that the punching mechanism cannot perform punching processing on the hinge surface, and the traditional punching equipment will jump parts during the processing; please refer to Figures 1-3, the utility model provides the following solutions:

A stamping machine for hinge production, comprising a workbench 2 and a stamping die assembly 3, and also comprising a hydraulic drive frame 1, the hydraulic drive frame 1 is arranged above the stamping die assembly 3, the hydraulic drive frame 1 comprises a gantry support frame 101, a horizontal platform 102 is arranged on the top of the gantry support frame 101, a stamping cylinder 103 is arranged above the horizontal platform 102, a locking head 1031 is arranged at the bottom of the stamping cylinder 103, and the locking head 1031 extends to the bottom of the horizontal platform 102, a bracket 105 is arranged at the bottom of the hydraulic drive frame 1, a slide 104 is arranged on both sides above the bracket 105, a top support cylinder 106 is arranged at the bottom of the bracket 105, the top support cylinder 106 is connected to the workbench 2 by bolts, a slot is arranged on the inner side of the slide 104, and the bracket 105 is telescopically connected to the top support cylinder 106;

After the processing operation is completed, the support cylinder 106 can push out the hinge metal parts inside the stamping die assembly 3 to complete the unloading operation;

The stamping die assembly 3 includes a lower die plate 301 and an upper die plate 302. The lower die plate 301 and the upper die plate 302 are connected by a guide column 303. The lower die plate 301 is slidably connected to the hydraulic drive frame 1 through a slide 104. The lower die plate 301 is located above the bracket 105. A locking plate 3022 is provided on the top of the upper die plate 302. The lock head 1031 is connected to the upper die plate 302 through the locking plate 3022. The upper die plate 302 and the upper die core 3021 can be controlled by the stamping cylinder 103 to perform stamping operations. An upper die core 3021 is arranged at the bottom, and the upper die core 3021 is telescopically connected to the upper die plate 302, which can play a role of buffer protection. A lower die core 3011 is arranged above the lower die plate 301, and the lower die core 3011 is connected to the lower die plate 301 by bolts. A punching seat groove 3012 is arranged inside the lower die core 3011, and the punching seat groove 3012 extends through and extends to the bottom of the lower die core 3011.
