Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] Such as Figure 1-4 shown.

[0039] A stainless steel car body cover plate with a thickness of 0.2 cm, which is first subjected to six consecutive deformations to form a right hook, such as figure 1 As shown, the shape of the arc of the rib and the arc of R298 is as follows figure 2 As shown, the forming process of the stainless steel car body cover plate is as follows image 3 shown. Aiming at the performance of stainless steel material, two bends are used to make it better shaped. The thickness of the stainless steel car body cover plate is 2.0mm. It can be formed by continuous roll cold bending, and the rolls are continuously rolled and deformed one by one. During the deformation process, the upper and lower rolls are used in pairs. Guide rollers and side rollers, such as Figure 4 .

Abstract

A continuous roller type cold-roll forming process for stainless steel covering panels of car bodies is characterized in that on the basis of the continuous roller type cold-roll forming, stainless steel bands are rolled to deform by the rollers sequentially, and are formed by upper rollers and lower rollers in pairwise under coordination of guide vertical rollers and side vertical rollers during deforming. Stainless steel covering panels formed by the process are fine in consistency, stable in quality and free of limit of length, twisting during production is avoided, and the process has the advantages of reasonability in angle and arc setting and long service life of equipment during use.

Description

technical field [0001] The invention relates to a manufacturing method of auto parts, in particular to a manufacturing method of a stainless steel car body cover plate, in particular to a continuous roll cold bending forming method of a stainless steel car body cover plate. 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. [0003] The stainless steel...
