Abstract

The invention discloses a punching die for pipe fittings, which relates to the technical field of stamping dies, and comprises an upper die base and a lower die base, a support block is fixed on the lower die base, and a lower groove is provided on the upper surface of the support block; There is a sliding die, and the sliding die is slidably matched with the lower die base. One end of the sliding die facing the support block is provided with a shrinking cavity, and the other end is fixed to the fixing plate on the lower die base through the first spring; There is a wedge, and the opposite surfaces of the wedge and the sliding die are respectively an upper inclined surface and a lower inclined surface for sliding fit; the upper template is connected with a pressing block through a second spring, and the lower surface of the pressing block is provided with an upper concave opposite to the lower groove. groove. The invention solves the problems that the pipe fittings are easily deformed and the pipe fittings have a complicated clamping structure existing in the existing pipe fitting necking mold.

Description

technical field [0001] The invention relates to the technical field of punching dies, in particular to a punching die for pipe fittings. Background technique [0002] The plastic processing of pipe fittings is a basic metal processing technology that makes the pipe plastically deformed under the action of external force to obtain the desired shape, size, structure and performance of the product. It mainly includes bending, bulging, flaring, shrinking , Flipping, etc. Among them, necking is a molding process in which the mouth of the pipe fitting is reduced through a necking die. An existing die for pipe fitting stamping and compression includes a lower die assembly with a shrinking cavity, and an upper die assembly for clamping the upper end of the pipe fitting. When the necking operation is performed, the upper end of the pipe fitting is clamped and fixed on the upper die assembly Upright, the pipe is erected, the press drives the upper die assembly to move downward, the ...
