The bending process requires a large investment and is very difficult to debug, resulting in a large waste during production. The roll bending equipment can be directly inserted in front of the cutting machine of the complex pressing production line in the previous process, and is composed of three groups of rollers. The surface profile of the rollers is designed according to the cross-section of the product, which is product-specific but easy to replace. The curvature of the roll bending can be adjusted according to the height of the middle roller. The adjustment of the roller is controlled by a servo, which can be automatically adjusted during production, thereby meeting the curvature requirements of the product, replacing the bending process in the subsequent process, and saving about 8% of the cost of a single product.
