Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] like Figure 1-4 shown.

[0043] A stainless steel roof side beam with a thickness of 2.0mm, with outer curling on the left side, arc reinforcement ribs in the middle, the overall radius of the arc in the middle is R348, and a hook on the right side. It adopts continuous roller cooling Bending forming, first undergoes 9 continuous deformations and simultaneously forms the left outer curl and the right hook, such as figure 1 shown. Then shape the rib arc and R348 arc, such as figure 2 shown. Finally, the forming roll pattern is carried out, such as image 3 shown. Aiming at the performance of stainless steel material, two bends are used to make it better shaped. It can be formed by continuous roll cold bending, and the rolls are continuously bent and deformed pass by pass, and the upper and lower rolls are used in pairs during the defo...

Abstract

The invention discloses a continuous cold roll forming method for a stainless steel vehicle roof boundary beam. The continuous cold roll forming method is characterized by adopting a continuous cold roll forming mode; a roller is used for continuously and gradually roll-forming; paired upper roller and lower roller are roll-formed during deformation; and a guide vertical roller and a side vertical roller are provided. The method has the advantages that: the consistency of a product is high, the quality of the product is stable, and the length of the product is not restricted, the phenomenon of bent distortion caused during the production is avoided, the change of angles and circular arcs is set rationally, and the equipment has a long service life.

Description

technical field [0001] The invention relates to a method for preparing auto parts, in particular to a method for preparing a stainless steel roof side beam, in particular to a continuous roll cold-bending forming method capable of connecting and producing super-long stainless steel roof side beams . Background technique [0002] In recent years, my country's high-speed rail, bullet train, subway and other businesses have developed rapidly, and the stainless steel market has been further developed, and the application of stainless steel section steel products is also in short supply. During this period, our company has developed a variety of stainless steel section steel products, which are widely used in high-speed rail, subway and other areas , it is precisely because the steel size requirements in these areas are getting higher and higher, and the mechanical properties of stainless steel materials are different, which is quite difficult for the cold bending industry. ...
