Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, and more specifically, to a metal product punching die. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. Punching is a common and widely used type of mold, used to drill holes in parts after production to facilitate subsequent assembly processes.

[0003] In the prior art, such as the punching device for metal products disclosed in CN210816973U, the device includes a machine base and a scrap bin. The top wall of the machine base has a scrap bin receiving cavity with a downward opening. Two slide rails are screwed to the left and right inner walls of the scrap bin receiving cavity. The slide rails are slidably connected to slide bars. The other side of the slide bars is screwed to the left and right side walls of the scrap bin. A pad is fixedly installed on the top of the machine base. A first scrap passage is opened through the top and bottom walls of the pad. A punching die mounting table is screwed to the top of the pad. A second scrap passage is opened through the top and bottom walls of the punching die mounting table. Four guide pillars are screwed to the top of the pad. The other ends of the four guide pillars are screwed to the bottom of the top plate. A hydraulic cylinder is screwed to the top wall of the top plate. The piston rod of the hydraulic cylinder passes through the top and bottom walls of the top and is fixedly connected to the top of the punching pressure plate. A punching head is fixedly provided at the bottom of the punching pressure plate.
