Abstract

The invention relates to a necking process suitable for a multi-duct aluminum alloy flat pipe. The process comprises the following steps of s1, necking of the flat pipe; s2, clamping of the flat pipe; and s3, shearing of the flat pipe. On one hand, synchronous machining of the flat pipe in the width direction and the thickness direction is achieved, deformation of the flat pipe is effectively prevented, the flat pipe necking effect is improved, the product quality is guaranteed, and the production efficiency is improved; and on the other hand, the shearing precision is guaranteed, and rapid shearing after flat pipe necking is achieved.

Description

technical field [0001] The invention belongs to the technical field of closing flat tubes, and in particular relates to a closing process suitable for multi-channel aluminum alloy flat tubes. Background technique [0002] The multi-channel aluminum alloy flat tube is a kind of thin-walled porous flat tube made of refined aluminum rods, hot extrusion, and surface anti-corrosion treatment. [0003] At present, in order to facilitate assembly and positioning, it is necessary to design an insertion step at both ends of the flat tube. The so-called insertion step refers to reducing the width of both ends of the flat tube to a certain size (usually called a closing), so that the ends of the tube body The width dimension becomes smaller to form a step. [0004] However, in the actual production process, the existing processing equipment is prone to the following defects: [0005] 1. It is difficult to implement closing processing simultaneously in the width direction and thicknes...
