[0001] The utility model relates to the technical field of stamping dies, in particular to an integrated metal stamping die for forming and stamping. Background Art

[0002] A stamping die is a special process equipment for processing materials into parts in cold stamping processing, called a cold stamping die. Stamping is to apply pressure to the material by using a die installed on a press at room temperature to cause separation or plastic deformation of the material.

[0003] In the processing of existing metal stampings, multiple steps are required. The metal material parts need to be bent and shaped, and then the formed metal parts are punched and perforated. There is currently no integrated equipment that can achieve the above functions, and it needs to be operated step by step, or passed through multiple devices on a conveyor line in sequence, resulting in low efficiency. Therefore, we propose an integrated metal stamping die for forming and stamping to solve this problem. Summary of the Utility Model

[0024] In this embodiment, a positioning mechanism is further included. The positioning mechanism includes two positioning plates 8, a gear 803 and two racks 802. The two racks 802 are respectively engaged on the front and rear sides of the gear 803. One end of the rack 802 is fixedly connected with a square plate 801. The two square plates 801 are respectively fixedly connected to the bottoms of the corresponding positioning plates 8. The two positioning plates 8 are respectively slidably connected to both sides of the lower die 1. Side plates are fixedly connected to the sides of the two racks 802 away from each other. One side of the side plate is fixedly connected with a compression spring 805. The other end of the compression spring 805 is fixedly connected with a baffle. The baffle is fixedly connected to the bottom of the lower die 1, so as to realize the reset of the gear 802. A fixing cylinder 804 is fixedly installed at the bottom of the lower die 1.

[0029] During the stamping process, the resistance received by the upper die 2 is monitored by the pressure sensor 601, and the monitoring result is transmitted to the controller 5. After the upper die 2 is in place, the pressure sensed by the pressure sensor 601 surges. After the controller 5 receives the signal that the pressure value of the pressure sensor 601 surges, it controls the electromagnet 704 to start, generate magnetism, magnetically attract the two iron sheets 703, and make the two sliding columns 7 approach each other, so that the sliding columns 7 are disengaged from the clamping connection with the vertical plate 201. Then start the hydraulic cylinder 6 to continue driving the installation frame 3 to move downward.
