Punching die

Abstract

The invention provides a punching die, and belongs to the field of die equipment. The punching die is used for performing punching forming on multiple holes in a metal tube and comprises an upper die base, a lower die base, a die shank, a male die, a female die, guide columns and guide sleeves, wherein the male die is installed on the lower surface of the upper die base, and the female die is installed on the upper surface of the lower die base. The male die is provided with a plurality of punching parts arranged in the extension direction of the cavity of the female die at intervals. The punching die further comprises an inclined slider core-pulling mechanism. The inclined slider core-pulling mechanism comprises a core-pulling slider; the core-pulling slider is provided with a plurality of second forming holes and is pulled out of the cavity of the female die when the punching die is opened; when the punching die is assembled, the core-pulling slider is inserted into the cavity of the female die and enables the second forming holes to correspond to the punching parts in a one-to-one mode. When the punching die punches multiple holes, the metal tube is does not deform easily, the forming quality of the holes is high, the machining efficiency is improved, and the machining cost is reduced.

Description

technical field [0001] The invention relates to the field of mold equipment, in particular to a punching mold. Background technique [0002] In mechanical processing production, it is often necessary to open holes or grooves on the side wall of metal pipes. If drilling or milling is used, the workload is large, the work efficiency is low and it is not safe. Using the punching die for punching can improve productivity, and the product quality is stable and safe, but there are some defects in the existing punching die. The existing punching die has only one punch, and only one hole can be punched at a time. , if punching continuous multiple holes on the metal pipe, the punching dies of the prior art need to repeat the punching action to complete the punching of multiple holes. [0003] The inventor found in the research that the stamping dies with multiple holes in the prior art have at least the following disadvantages: [0004] First, when punching continuous holes, the me...
