The tool 15 is set in a ring shape. The operator places the material to be stamped on the upper end of the ring plate 7. At the same time, the lower end of the material fits with the upper end of the lower die 6. The movable plate 12 drives the upper die 14 and the tool 15 to slide downward. The material is accurately cut through the cooperation between the tool 15 and the ring plate 7 to reduce burrs caused by irregular edges of the material in the subsequent stamping process. Then the push plate 3 pushes the lower die 6 upward, so that the lower die 6 drives the cut material to slide upward, and the lower die 6 and the upper die 14 cooperate to perform stamping processing on it.

[0022] The lower end of the base 1 is fixedly connected to a hydraulic cylinder 2, the output end of the hydraulic cylinder 2 is slidably connected to the base 1, and the output end of the hydraulic cylinder 2 is fixedly connected to the lower end of the push plate 3, and the push plate 3 is pushed or pulled by the hydraulic cylinder 2 to slide longitudinally.

[0023] A slot 4 is provided inside the push plate 3, and a heating wire 5 is fixedly connected inside the slot 4. The push plate 3 is heated by the heating wire 5, and the heat is transferred to the lower mold 6 at the same time to preheat the material.
