High-precision flared fitting forming tool

Abstract

A high-precision flared fitting forming tool is characterized by comprising a pipe body; the pipe body is dived into an upper pipe body end, a middle pipe body end and a lower pipe body end; the upper pipe body end is a necking-down end; the middle pipe body end is a transition segment; the lower pipe body end is a flaring end; the necking-down end comprises a necking-down body and a necking-down circular arc; the flaring end comprises a flaring body and a flaring circular arc; when a pipe fitting is machined, the stamping necking manner is adopted; the machining time of the pipe fitting is greatly reduced, and the technical characteristics of stamping necking are combined; the necking precision is effectively improved, and the product quality is improved; meanwhile, the machining time is reduced, the machining speed and the efficiency of the pipe fitting are improved, and cost generated by purchasing of a plurality of necking-down devices is saved; and the manual cost is reduced, and meanwhile energy losses are reduced.

Description

technical field [0001] The invention relates to the technical field of an exhaust pipe of an automobile exhaust system, and relates to a bell mouth pipe fitting forming tool. Background technique [0002] It involves a bell-mouth pipe fitting forming tooling in the field of automobile exhaust system exhaust pipe. The bell-mouth pipe fitting forming tooling circulating in the market usually uses CNC shrinking and single-side flaring, while CNC shrinking There are generally problems of poor precision and uncontrollable length of pipe fittings. At the same time, CNC shrinking and unilateral flaring are performed separately, and the operation is complicated and complicated, and the processing speed is slow. Contents of the invention [0003] The present invention proposes a high-precision bell mouth pipe forming tool to solve the problems of poor precision, uncontrollable length of pipe fittings, complicated and complicated processing procedures and slow proc...
