[0002] In the field of metal processing, aluminum, as a lightweight and highly plastic metal material, is widely used in construction, transportation, aerospace and other industries. In the production and processing of aluminum, straightening is an indispensable link. Its purpose is to eliminate the internal stress of aluminum generated during the processing, improve its straightness and improve product quality. The aluminum profile straightening machine is a device specially used to straighten aluminum profiles. In the process of aluminum profile processing, due to the material itself or the processing technology, the aluminum profile may have shape problems such as bending and twisting. At this time, an aluminum profile straightening machine is needed to straighten and correct it. The working principle of the aluminum profile straightening machine is to utilize the plastic deformation characteristics of the material when it is stressed. By applying external force to the aluminum profile, the internal stress is redistributed, thereby achieving the straightening effect. The straightening machine generally includes a front clamping mechanism and a rear clamping mechanism that work together to straighten the aluminum profile. During the clamping process, the position of the front clamping mechanism or the rear clamping mechanism needs to be locked.

[0003] The existing Chinese utility model patent with publication number CN204747108U discloses a straightening machine for straightening a profile, comprising a machine body, a telescopic cylinder arranged on the machine body, a first main machine fixedly connected to the telescopic cylinder, and a second main machine arranged on the machine body, wherein the profile is stopped by a stop protrusion in the jaws of the second main machine to ensure that the straightening clamp accurately clamps one end of the profile, and then the profile is straightened by the first main machine, so that the straightened profile retains the original length. However, the above-mentioned straightening machine only straightens a single aluminum material, and cannot freely control different numbers of aluminum materials to be clamped side by side, making the straightening operation of multiple aluminum materials complicated and inefficient.
