The processing table and the secondary bending table are set to bend the car box floor twice, and During the first bending, the car box floor on the processing table can be directly lifted by the suction cup and sent to the secondary bending table. During the transportation process, the car box floor is directly driven to rotate 180 degrees, and the suction cup drives the car box floor to rotate and move, which reduces manpower consumption, and the bending mechanism can bend two car box floors each time, which improves production efficiency. It is divided into two times, and the bending efficiency is low. At the same time, the bending position needs to be calibrated during bending, which further reduces the bending efficiency. For this reason, a car box floor side bending device is proposed, which is convenient for bending two sides of the car box floor at the same time, and is convenient for the bending roller to automatically center the position before it reaches the car box floor, thereby improving the bending accuracy and further improving the bending efficiency.
