Embodiment 1
[0026] Adopt variable cross-section profile roll forming device of the present invention, the section of formed profile is Figure 5 U-shaped section shown. The metal sheet used is 304 stainless steel with a forming thickness of about 1mm. The forming speed can be set to 200mm / s according to the characteristics of the plate material to be processed, and the rolling speed of the roll can be set by the forming speed. After roll forming, the Figure 5 The U-shaped profile with variable cross-section is shown.
[0027] To sum up, the variable cross-section profile roll forming device described in the present invention has low manufacturing cost, simple debugging, and is convenient for mass production.

The invention relates to a variable cross-section roll bending forming method and a device, belonging to the field of roll bending forming technology and equipment, which are used for solving the problem of a variable cross-section material of a high-efficiency roll bending forming. The method and the device are characterized in that an uncoiled metal structural material is flattened by a strip leveling machine, then the structural material is subjected to the variable cross-section roll bending forming one by one by a variable cross-section roller group containing a special roller, and finally the produced variable cross-section structural material is cut and stacked according to a set length. By the adoption of the method and the device, a servo-control device is not needed to be installed in the whole production line, the assembly and debugging are simple and easy, cost is lower, and a batch production is facilitated.
Description
technical field [0001] The invention relates to a variable cross-section roll forming method and a device thereof, which belong to the field of roll forming technology and equipment and are used to solve the problem of high-efficiency forming variable cross-section profiles. Background technique [0002] Roll forming is an efficient and advanced sheet metal forming process technology. It continuously bends metal strips such as coils and strips transversely through sequentially arranged multi-pass forming rolls to make profiles with specific cross-sections. The products produced by the roll forming process are called roll bending profiles. The traditional roll forming method has an inherent defect, that is, it can only produce profiles with a fixed cross-sectional shape, and cannot produce profiles with a variable cross-sectional shape. In order to produce roll-bending profiles with variable cross-section shapes, some emerging technologies have been developed in recent year...
