Bending-compression mould for processing fastener

Abstract

A traditional common mould used for carrying out bending-compression assembly between two parts comprises two moulds: a transversal bending mould and a longitudinal bending mould, which has a fussy and complicated assembly process and low production efficiency. The invention provides a bending-compression mould, which comprises a lower positioning concave die and a lower punching die matched withthe lower positioning concave die for use, and is characterized in that an upper push plate and a connecting block are arranged above the lower punching die; the bottom part of the connecting block is fixedly arranged on the upper surface of the upper push plate; the lower punching die and the upper push plate are connected through a plurality of guide posts penetrating through the upper push plate; the bottom part of each guide post is fixedly connected onto the lower punching die; the top part of the guide post is provided with a stop block; a plurality of booster springs and a plurality ofpre-stressing springs are arranged between the upper push plate and the lower punching die; a plurality of transversal bending tools are fixed at the bottom part of the lower punching die; a plurality of longitudinal bending tools penetrating the lower punching die are fixed on the upper push plate; and the tool bits of the longitudinal bending tools are arranged next to the side walls of the transversal bending tools. By adopting the bending-compression mould, the process is simplified, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a mold for bending and pressing assembly of products, in particular to a bending and pressing mold for bending and pressing a buckle used for assembly between two parts and completing the assembly. Background technique [0002] At present, the commonly used mold used for bending and pressing assembly between two parts is composed of two molds: a transverse bending die and a longitudinal bending die. Usually, it is divided into the following assembly processes: ① place the two parts, ② press the two Components, ③Horizontal bending die performs horizontal semi-finished bending on the "┃" vertical plate, and bends it into a "━┓"-shaped folding plate, ④Remove the semi-finished product and transfer it to the next station, ⑤Place the two parts again components, ⑥press the two parts again, ⑦longitudinal bending die for longitudinal bending, and [0003] The "━┓"-shaped folding plate is processed into a "┏┓"-shaped buckle, and the two...
