Ultra-thin copper pipe machining and preparing method

Abstract

The invention discloses an ultra-thin copper pipe machining and preparing method. The method comprises the following steps that pipe unwinding is conducted, and specifically, a rolled copper pipe is unwound through pipe unwinding equipment; the copper pipe is guided, and specifically, the copper pipe is guided through a guiding structure to be straightened; film drawing is conducted on a mold, oil is added for lubrication, and then drawing is conducted through a mold with a diameter smaller than that of the mold; turning over and pipe pulling are conducted, and specifically, the copper pipe is pulled by winding the copper pipe around a rotating disc which rotates in a reverse direction; and pipe coiling is conducted, and specifically, the copper pipe is coiled through pipe coiling equipment. According to the ultra-thin copper pipe machining and preparing method, the copper pipe is preliminarily straightened through the straightening structure, the copper pipe is drawn and thinned through a series of operations, the phenomenon that the copper pipe is broken in the production and machining process is effectively avoided, resources are effectively saved, and the problem that an existing copper pipe cannot be thinned is solved.

Description

technical field [0001] The invention belongs to the technical field of ultra-thin copper tubes, in particular to a processing and preparation method for ultra-thin copper tubes. Background technique [0002] Ultra-thin copper tube, also known as purple ultra-thin copper tube, is a kind of non-ferrous metal tube. It is a pressed and drawn seamless tube. Ultra-thin copper tube has strong and corrosion-resistant characteristics, and has become a modern contractor It is the first choice for the installation of tap water pipes, heating and cooling pipes in all residential commercial buildings. It is light in weight, good in thermal conductivity, and high in low temperature strength. It is often used in the manufacture of heat exchange equipment, and is also used in the assembly of low temperature pipelines in oxygen production equipment. The diameter is small. Ultra-thin copper tubes are often used to transport liquids under pressure and as pressure measuring tubes for instrument...

[0002] Ultra-thin copper tube, also known as purple ultra-thin copper tube, is a kind of non-ferrous metal tube. It is a pressed and drawn seamless tube. Ultra-thin copper tube has strong and corrosion-resistant characteristics, and has become a modern contractor It is the first choice for the installation of tap water pipes, heating and cooling pipes in all residential commercial buildings. It is light in weight, good in thermal conductivity, and high in low temperature strength. It is often used in the manufacture of heat exchange equipment, and is also used in the assembly of low temperature pipelines in oxygen production equipment. The diameter is small. Ultra-thin copper tubes are often used to transport liquids under pressure and as pressure measuring tubes for instruments. The existing problem is: in the production of copper tubes from thick copper tubes to ultra-thin copper tubes, there are very high requirements on the production methods. Once that link goes wrong, it will cause the copper tubes to break during production. Or the problem of uneven processing thickness occurs. Whether the copper tube is smooth at the initial input is also the key to the thinning of the copper tube. Once the copper tube is not straight when the film is drawn by the mold, the problem of copper tube breakage will occur.
