A processing method for preparing square tubes with thin-wall strips

Abstract

The invention discloses a machining method of thin-walled strip prepared square tubes, and belongs to the technical field of square tube forming technology. The method mainly comprises the following steps: firstly, uncoiling of a strip coil: uncoiling a strip coil and outputting a strip, secondly, primary buffering: enabling the strip to be at a tensioning state, thirdly, actively conveying the strip: enabling the strip to be downward output to the downstream under the action of traction force, and forming openings in edges of the two sides of the strip during conveying, fourthly, secondary buffering: enabling the strip to be output at a constant speed, without the action of traction force, and controlling the active conveying frequency of the strip, fifthly, application of a lubricant, sixthly, forming, seventhly, closing the opening, eighthly, welding at high frequency, ninthly, cooling, tenthly, eliminating residual liquor, eleventhly, accurately sizing a tube section, and twelfthly, cutting. The method solves the technical problems that the existing thin-walled square tubes are poor in forming quality and low in production efficiency, and can be widely applied to the manufacture of thin-walled square tubes.

Description

technical field [0001] The invention relates to a processing method for a pipe, more particularly to a processing method for preparing a square pipe with a thin-walled tape, 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 ...
