Pipe fitting punch die based on flexible slide block

Abstract

The invention relates to a pipe fitting punch die based on a flexible slide block and a method. The die comprises a lower die holder, a position pipe, a drain plug, a terrace die, a die, a fixed plate, a base plate, a spring, a push rod, a die handle, an upper die holder, another fixed plate, a floating wedge, a supporting seat, polyamine, a filling block, solid particles and the like, wherein an inner cavity of the position pipe is internally provided with the solid particles, the terrace die vertically arranged is movably arranged in a radial hole of the position pipe, one end of the terrace die is positioned among the solid particles, the upper end of the floating wedge vertically arranged is connected on the upper die holder, the lower end thereof passes through the position pipe to be contacted with the solid particles, the filling block is arranged between the lower die holder and the position pipe to support the position pipe, and the position of the filling block corresponds to the position of the terrace die. The invention drives the terrace die to move outward to punch by taking the solid particles as the slide block, is particularly suitable for multi holes to simultaneously punch outward, has simple structure and high efficiency, and is easy to take pieces due to outward bristles of the punch.

Description

technical field [0001] The invention belongs to punching die technology, in particular to a punching forming die driven by solid particles as flexible sliders. Background technique [0002] The processing of holes on the pipe is mainly mechanical processing, including drilling, milling, etc. In mass production, punching is used instead of drilling and milling, which has the characteristics of high production efficiency and reduced processing costs. At present, for the processing method of punching, when punching ordinary pipe fittings, the commonly used structure is that the punch is outside and the die is inside, and the punch impacts the pipe from outside to inside under the action of external force to form punching holes; however, this kind of punching If the pipe is empty, the burr of the pipe is inward after punching and is on the inner wall of the pipe, resulting in poor punching quality and damage to the pipe; when the burr is too large after punching, the burr will c...
