Anti-rust mark automatic metal pipe necking machine

Abstract

The invention discloses an anti-rust mark automatic metal pipe necking machine. The anti-rust mark automatic metal pipe necking machine structurally comprises an intelligent controller, a metal pipe pressing structure, a hydraulic necking device, an equipment supporting table, a radiating maintenance port and a metal pipe backing plate; the equipment supporting table is mounted on the ground of aworkshop; the radiating maintenance port is nested in the centre of the front surface of the equipment supporting table; and the metal pipe pressing structure is vertically mounted in the centre of the upper surface of the equipment supporting table. According to the automatic necking machine, rust and paint on a surface can be effectively cleaned before a metal pipe is subjected to necking machining by mounting an automatic rust removal mechanism, so that the rust and the paint are prevented from attaching to the inner wall of a mould to cause a depression in the surface when the metal pipe is subjected to subsequent machining; after the machining is ended, the metal pipe is removed easily without manually knocking, so that the collision on the surface of the metal pipe is avoided; and therefore, the metal pipe necking quality is effectively improved, and the flatness of the surface of the metal pipe after being necked is improved.

Description

technical field [0001] The invention relates to the field of shrinking machines, in particular to an automatic shrinking machine for rust-proof metal pipes. Background technique [0002] In the machining process, in order to meet the process requirements, it is necessary to shrink the pipe raw materials such as copper pipes, so that the outer diameter of the copper pipe meets the process requirements. With the rapid development of science and technology, automatic necking machines have become more and more It is common, but the current technical considerations are not perfect, and it has the following disadvantages: when the automatic necking machine is working, it puts the pre-formed cylinder or pipe blank into the necking mold and shrinks its mouth, but some metal pipes surface If it has been rusted or painted, after it is directly put into the shrinking mold for processing, the rust and paint on the surface will fall off directly and be squeezed to fit on the inner wall o...

[0002] In the machining process, in order to meet the process requirements, it is necessary to shrink the pipe raw materials such as copper pipes, so that the outer diameter of the copper pipe meets the process requirements. With the rapid development of science and technology, automatic necking machines have become more and more It is common, but the current technical considerations are not perfect, and it has the following disadvantages: when the automatic necking machine is working, it puts the pre-formed cylinder or pipe blank into the necking mold and shrinks its mouth, but some metal pipes surface If it has been rusted or painted, after it is directly put into the shrinking mold for processing, the rust and paint on the surface will fall off directly and be squeezed to fit on the inner wall of the mold, which will cause subsequent processing of metal pipe fittings due to rust and paint in the mold. The surface is sunken, which reduces the production quality of the product. At the same time, at the end of the processing, the metal tube compression structure and the metal tube have a strong bite force. The metal tube needs to be manually knocked and loosened before it can be removed, which will cause bumps on the surface of the metal tube and affect the surface of the metal tube. Flatness
