Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. However, the uses and purposes of these exemplary embodiments are only used to illustrate the present invention, and do not constitute any form of limitation to the actual protection scope of the present invention, nor limit the protection scope of the present invention thereto.
[0036] Such as figure 1 As shown, the present invention provides a kind of processing method of thin-walled tape preparation square pipe, and the processing method of described thin-walled tape preparation square pipe mainly comprises the following steps: (1) tape coil uncoiling: tape material coil Unfold and output the belt material; (2) Primary buffer: make the belt material in a tensioned state; (3) Actively convey the belt material: the belt material is output downstream under the action of traction, and during the conveying process, the belt material The side edge is broke...

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 ...
