Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, and in particular to a straightening device and a processing method for aluminum profile processing. Background Art

[0002] In the aluminum profile processing industry, traditional straightening devices mainly focus on the straightening effect of aluminum profiles, while the cutting function is usually completed by independent equipment. This separate processing method not only increases the complexity of the production process, but also may affect the processing accuracy and stability of aluminum profiles. As the market's requirements for aluminum profile processing quality continue to increase, traditional straightening devices can no longer meet current processing needs.

[0003] For example, the aluminum profile straightening devices disclosed in China's Patent No. 116116935 and Patent No. 113967677 do not have a cutting function, which requires the use of additional cutting equipment during the processing. This not only increases production costs, but may also reduce processing accuracy due to coordination problems between equipment; at the same time, there may be deficiencies in the straightening effect, such as the aluminum profile still being bent or twisted after straightening. This affects the aesthetics and performance of the aluminum profile and reduces the market competitiveness of the product. Even if some straightening devices try to combine cutting functions, it is often difficult to keep the aluminum profile stable during the cutting process. Aluminum profiles are prone to shaking or displacement during cutting, resulting in reduced cutting accuracy and efficiency.

[0004] In view of the above-mentioned problems, the aluminum profile processing industry urgently needs a new type of straightening device, which can integrate the cutting and straightening functions into one, reduce the complexity of the production process, and improve processing efficiency and precision; it can adapt to aluminum profiles of different shapes and sizes, ensure stability and precision during cutting and straightening, help improve the processing efficiency and quality of aluminum profiles, and promote the development of the aluminum profile processing industry.
