[0028] In summary, the present application has at least one of the following beneficial technical effects:

[0029] 1. The middle cross beam to be processed is conveyed to the feeding lifting feeding mechanism by an external conveying belt, the feeding grabbing mechanism grabs the middle cross beam to be processed and places the middle cross beam on the lower die base, the driving structure drives the upper die base to descend along the vertical direction and cooperates with the lower die base to bend and form the middle cross beam, the discharging grabbing mechanism grabs the bent middle cross beam and places the middle cross beam on the drilling and tapping mechanism, the drilling and tapping mechanism drills and taps the middle cross beam, and finally the stacking mechanism collects and stacks the middle cross beam after drilling and tapping; the auxiliary manual production line replaces manual operation, reduces the technical requirements and labor intensity of workers, improves the consistency of the bending quality of the middle cross beam, and improves the production efficiency;

[0030] 2. During the movement of the feeding moving plate towards the material support plate, the linkage component drives the drive gear to rotate in the forward direction and, through the toothed belt, drives the driven gear to rotate in the forward direction. This, in turn, drives the lifting plate to descend vertically through the transmission toothed part, facilitating the feeding gripping structure to grip the middle crossbeam to be processed and the unloading gripping structure to grip the bent middle crossbeam. During the movement of the feeding moving plate towards the lower mold base, the linkage component drives the drive gear to rotate in the reverse direction and, through the toothed belt, drives the driven gear to rotate in the reverse direction, causing the lifting plate to rise vertically. Then, it drives the drive gear to rotate in the forward direction and, through the toothed belt, drives the driven gear to rotate in the forward direction, causing the lifting plate to descend vertically.

[0031] 3. The crossbeam to be processed is placed above the groove of the mold cavity of the lower mold base. The drive structure drives the upper mold base to descend vertically, pressing the middle part of the crossbeam into the mold cavity groove. The pressed part of the crossbeam abuts against the support plate, causing the support plate to descend vertically. The elastic element undergoes elastic deformation under force and maintains the tendency to elastically return to its original position. After bending is completed, the drive structure drives the upper mold base to rise vertically. The elastic element elastically returns to its original position, causing the support plate to rise vertically and push the crossbeam out of the mold cavity groove, which facilitates demolding. The guide pin also slides along the guide groove as the support plate descends, guiding and limiting the sliding of the support plate and improving the stability of the sliding of the support plate.

[0032] 4. When the feeding moving plate moves toward the first fixed plate and triggers the first touch switch, the air pump pumps air, and the clamping cylinder drives the two clamping plates to move away from each other; when the unloading moving plate moves toward the first fixed plate and triggers the second touch switch, the air pump pumps air, and the clamping cylinder drives the two clamping plates to move toward each other, thus achieving the effect of multi-mechanism linkage.
