[0029] The movable frame 100 is provided with a plurality of mounting platforms 300, which are arranged along the direction of the crossbeam plate. A hydraulic cylinder 301 is installed on the top of the mounting platform 300. The piston rod of the hydraulic cylinder 301 is arranged downward and the movable end of the piston rod is connected to the pressure plate 302. In use, the pressure plate 302 presses downward onto the workpiece to be processed.

[0030] To improve the reinforcement effect between parallel crossbeams, the middle of several parallel crossbeams is reinforced by reinforcing plates 203. The reinforcing plates 203 are perpendicular to the crossbeams on both sides and parallel to the connecting side plates 202. The reinforcing plates 203 are detachably installed in the middle of the crossbeams. For details, see [link to details]. Figure 2 The crossbeams on both sides are provided with insertion slots, and the two ends of the reinforcing plate 203 are provided with insertion blocks. After assembly, the insertion blocks are aligned and inserted into the insertion slots. To achieve stable installation of the reinforcing block 203, the reinforcing plate 203 is pressed against the pressure block at the bottom of the piston rod of the second cylinder 204 during use. The reinforcing plate 203 is pressed against the pressure block and the center of the "U"-shaped support frame 205.

[0031] In use, the movable frame is pushed to the designated location by the casters, then the brake pads are closed for positioning. The height of the mounting plate is adjusted by rotating the threaded buckle, causing the mounting plate to press against the movable frame. The operating platform is then placed on the pad, and the first cylinder on the mounting plate is driven. This first cylinder lowers the limiting rod. After the limiting rod descends, the protrusion at its front end presses against the limiting guide rail in the limiting groove on the operating platform. The corner of the "7"-shaped limiting rod then limits its left and right directions, achieving the effect of limiting the rod. Finally, the connecting side plate is locked to the crossbeam of the operating platform, and a second cylinder and a hydraulic cylinder are installed on the movable frame. A reinforcing plate is installed between the parallel operating platforms. The reinforcing plate is inserted into the crossbeam of the operating platform to achieve the effect of reinforcement.

It should be noted that this solution adopts a manual assisted operation method, that is, semi-manual and semi-mechanical processing. Therefore, the workpiece is placed in the limiting groove by manual operation and manual limiting. The hydraulic cylinder is controlled by the start switch to lower and press down the workpiece according to the set height. This makes the workpiece generate a downward arc before welding. Then, during the welding process, it is counteracted by the raised arc, which ultimately optimizes the curvature problem of the product.
