Abstract

The invention discloses a machining method for a thin-wall squared tube and belongs to the technical field of square tube forming processes. The machining method for the thin-wall squared tube mainly includes the following steps that 1 a strip roll is decoiled, wherein the strip roll is unfolded and a strip is discharged; 2 the strip is conveyed actively, wherein the strip is discharged downstream under the action of traction force; 3 buffering speed governing is conducted, wherein the strip is discharged at a constant speed without the action of tensile force, and the active conveying frequency of the strip is controlled; 4 lubricant coating is conducted, wherein the two surfaces of the strip are coated with lubricants; 5 forming is conducted, wherein the strip is gradually bent in a cold mode, so that the strip forms a tube blank with a weld joint and a square section, and the weld joint is located on the upper surface of the tube blank; 6 high-frequency welding is conducted; 7 cooling is conducted; 8 residual liquor is cleaned away; 9 the tube section is accurately shaped; 10 cutting is conducted. The machining method solves the technical problems that existing thin-wall squared tubes are poor in forming quality and low in production efficiency, and the machining method is widely applied to manufacturing thin-wall squared tubes.

Description

technical field [0001] The invention relates to a processing method of a pipe, more particularly to a processing method of a thin-walled square pipe, and belongs to the technical field of square pipe forming technology. Background technique [0002] In the automobile manufacturing industry, welded pipes are often used to provide a channel for compressed high-temperature air to flow through. These welded pipes are different from structural pipes. They do not need to withstand high pressure, so they are often made of thin-walled materials. Different structural shapes to meet its use value. [0003] For example, the production of intercooler high-frequency welded pipe is mainly made of thin-walled aluminum alloy strip welding, and the diameter-thickness ratio of the intercooler high-frequency welded pipe is greater than 50, that is, the equivalent diameter of the intercooler high-frequency welded pipe / the thickness of the raw material More than 50, the wall thickness of the in...
