High precision punching die

Abstract

The invention provides a high precision punching die, and belongs to the field of die equipment. The high precision punching die is used for punching molding of multiple holes in a metal pipe, the high precision punching die comprises an upper die base, a lower die base, a die handle, a male die, a female die, a guide column and a guide sleeve, the male die is installed on the lower surface of theupper die base, 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, and the multiple punching parts are arranged at intervals in the extending direction of a cavity of the female die; the high precision punching die comprises an inclined sliding block core-pulling mechanism, the inclined sliding block core-pulling mechanism comprises a core-pulling sliding block, the core-pulling sliding block is provided with a plurality of second molding holes, and the cavity of the female die is pulled out when the high precision punching die is opened; and when the high precision punching die is closed, the core-pulling sliding block is inserted into the cavity of the female die, the multiple second molding holes correspond to the multiple punching parts in a one-to-one manner. When the high precision punching die is used for punching the multiple holes, the metal pipe is not prone to deformation, the hole molding quality is high, the machining efficiency is improved, and the machining cost is saved.

Description

technical field [0001] The invention relates to the field of mold equipment, in particular to a high-precision 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 continuou...

Problems solved by technology

[0007] The purpose of the present invention is to provide a high-precision punching die to improve the prior art punching dies when the metal pipe is easily deformed and the quality of the hole is low, which reduces the product qualification rate.
