Universal round tube necking and flaring forming tool

Abstract

The invention discloses a universal round tube necking and flaring forming tool which comprises a bilaterally movable device fixedly connected with a tool. The tool particularly comprises a horizontal round tube, a screw, a cylindrical connecting rod, a round tube necking die and a cylindrical flaring die, the left of the round tube is narrow, the right of the round tube is wide, the screw, the cylindrical connecting rod, the round tube necking die and the cylindrical flaring die are sequentially arranged inside the round tube from left to right, the screw is arranged at the inner leftmost end of the round tube and fixedly connected with the round tube, one end face of the connecting rod is fixedly connected with a screw rod end of the screw, a round tube necking die fixing block fixedly sleeves the middle of the connecting rod, the other end face of the connecting rod is fixedly connected with a flaring die end cover, and a thread is arranged on an outer ring of the flaring die end cover. The universal round tube necking and flaring forming tool has the advantages that design steps are simplified, the same necking and flaring effects are achieved, the cost of an enterprise is saved, working efficiency is improved, and wide-range popularization in the production industry is facilitated.

Description

Technical field [0001] The invention relates to a tooling, in particular to a universal round tube necking and flaring forming tooling. Background technique [0002] In the processing technology, the necking is a forming process in which the pre-formed cylindrical or pipe blank is reduced by a necking die. The necking process is widely used, and can be used for necking processing of bullet shells, shell shells, steel gas cylinders, bicycle frame risers, bicycle seat saddle tubes, steel pipe drawing, etc. For slender tubular parts, sometimes using necking instead of deep drawing can achieve better results. Corresponding to the necking is the flaring process. Flaring is a forming method to enlarge the radial dimension of the end of a pipe or hollow part. [0003] The necking die is a die that reduces the radial dimension of the end of a hollow blank or a tubular blank. The flaring die is a die that expands the radial dimension of the end of a hollow blank or a tubular blank. [0...

AI Technical Summary

Problems solved by technology

It can be seen from this that the necking and flaring of a round pipe or cylindrical part require two sets of tooling and two operating steps, which is not only cumbersome to operate, wastes the production cost of the tooling, but also takes a long time, which is not conducive to cost saving for enterprises
