[0002] Aluminum profiles are usually used in applications such as frames to achieve a fixing effect. During the processing of aluminum profiles, one of the most common problems is that they need to be straightened during use. Currently, when straightening, the method of using a straight slide rail to drive a pressure machine is mostly adopted to straighten aluminum profiles. For example, in a straightening machine for processing aluminum profile brackets with the patent application number CN202110759892.3, it includes a bottom support, a gantry support, a pair of moving components, and a control box. The gantry support is installed on the bottom support. A pair of chutes are opened on both sides of the bottom support. A pair of moving components are provided at the bottom ends on both sides of the gantry support and are matched with the pair of chutes. The control box is installed on one side of the bottom support. A sliding hydraulic straightening mechanism is provided on the gantry support. The beneficial effect of the present invention is that this straightening equipment for processing aluminum profile brackets has a simple structure and is easy to operate. By cooperating the active pushing mechanism with the sliding hydraulic straightening mechanism, the straightening of two aluminum profiles can be completed at one time without affecting each other, and at the same time, feeding and detection are automatically completed. It can not only save the operation steps of workers, reduce the workload and labor cost, but also adopt a split structure design, and the replacement and disassembly of components are simple, effectively reducing the maintenance workload.

The dial block 602 can longitudinally slide in the one-way driving dial 6 through the buffer guide rod 601 and the spring 603. Thus, when the one-way driving dial 6 moves leftward with the correcting connecting seat plate 5, the one-way sending gear 901 can be driven to rotate clockwise by the dial block 602. The rotation of the one-way sending gear 901 can drive the driving feeding wheel 9 to rotate. Finally, the lower end of the driving feeding wheel 9 is fixedly connected with the one-way sending gear 901. A one-way tooth groove 90101 adapted to the rear end of the dial block 602 is provided on the ring edge of the one-way sending gear 901. When the dial block 602 moves partially leftward, the dial block 602 drives the one-way sending gear 901 to rotate clockwise.
