The beneficial effects of the utility model are:

The device of the utility model adopts a progressive forming rack, which gradually realizes the forming of the entire rack with unlimited length, and is not limited by the size of the working table of the stamping machine tool. It effectively solves the problem of plate fracture due to insufficient material properties when the overall stamping of the rack is used.

The stamping forming device has the function of elastic pressing. When the rack is formed, the pressing die first presses the rack in the forming part, and then the rack is formed by pressing. Effectively prevent the formed rack part from being deformed by the tensile force generated in the subsequent stamping process, and improve the dimensional accuracy of the rack workpiece.

The bottom mold is provided with a material inlet and a material outlet, which can avoid the lateral movement caused by the force during the stamping and forming process of the plate, and improve the forming accuracy of the rack.

The device is equipped with a feeding mechanism and a discharging mechanism, and the entire rack forming process is automatically completed, which improves production efficiency and reduces the difficulty of rack processing operations.
