Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] Such as Figure 1-4 shown.

[0037] A stainless steel side wall lower side beam, forming the outer curling at the same time as forming the right-angled side, and forming the rib boss when it is about to be formed to the profile, such as figure 1 The schematic diagram of the simultaneous forming of the right-angled edge and the outer curling edge is shown, such as figure 2 Forming of the rib bosses shown, such as image 3 Forming roll patterns for stainless steel sidewall sill beams shown. Aiming at the performance of stainless steel material, two bends are used to make it better shaped. The thickness of the lower wall panel of the stainless steel side wall is 1.5mm. 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 use...

Abstract

A continuous cold-roll forming method for a stainless steel side wall bottom edge beam is characterized in that the stainless steel side wall bottom edge beam is continuously rolled and deformed step by step through rollers by means of continuous cold-roll forming, an upper roller and a lower roller are used for roll forming pairwise during deformation, and a vertical guide roller and a lateral vertical roller are used in a matched manner. The continuous cold-roll forming method has the advantages that the stainless steel side wall bottom edge beam is fine in uniformity and stable in quality and is not limited in length, torsion generated in production is avoided, right-angle change is reasonable, and the stainless steel side wall bottom edge beam is long in service life.

Description

[0001] technical field [0002] The invention relates to a manufacturing method of profiles, in particular to a manufacturing method of a stainless steel side wall lower beam, in particular to a continuous roll cold bending forming method of a stainless steel side wall lower beam. Background technique [0003] In recent years, my country's high-speed rail, bullet train, subway and other businesses have developed rapidly, and the application of stainless steel section steel products is also in short supply. At present, a variety of stainless steel section steel products are widely used in high-speed rail, subway and other areas, precisely because of the size requirements of section steel in these areas It is getting higher and higher, and the mechanical properties of stainless steel materials are different, which is quite difficult for the cold bending industry. [0004] At present, the lower side beam of the stainless steel side wall is taken as an example. Most of them a...
