Punching device capable of automatically cooling outer wall of punching cavity

Abstract

The invention relates to the technical field of punching, and discloses a punching device capable of automatically cooling the outer wall of a punching cavity. The punching device comprises an upper template. Guide rods are fixedly mounted at the left end and the right end of the bottom of the upper template. The left end and the right end of the bottom of the upper template are fixedly connectedwith a lower template through lifting devices. A punching block is fixedly mounted at the upper end of the lower template. Guide rail groove bodies are fixedly mounted at the left end and the right end of the punching block. Moving plates are movably mounted at the lower ends of the guide rail groove bodies, and first springs are fixedly mounted at the lower ends of the moving plates. According tothe punching device capable of automatically cooling the outer wall of the punching cavity, the guide rods enter the guide rail groove bodies downwards to drive the moving plates to move, the movingplates drive V-shaped connecting rods to move, piston rods are driven by cooperating with the action of rotating wheels to move in piston barrels, and therefore condensation liquid can be automatically drawn from a liquid storage groove body to enter a condensation liquid pipe, and the effect of cooling the punching cavity is achieved.

Description

Technical field [0001] The invention relates to the technical field of stamping, in particular to a stamping device that can automatically cool the outer wall of a stamping cavity. Background technique [0002] Stamping relies on presses and dies to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces (stamping parts) of the required shape and size. Many motor housings rely on stamping The motor shell formed by the process has high precision and consistent specifications, and it is not easy to be thermally deformed during use. [0003] During stamping overshoot, it is easy to cause heat to be generated on the inner wall of the mold cavity. If the heat is not dissipated in time, it may cause the mold to be heated and deform during the stamping process, resulting in the stamping parts produced not meeting specifications. The current heat dissipation method is Applying the extremely volatile "quick-drying ...
