[0016] 2. The welded base of the bottom frame forming device of the present invention is a hollow structure and avoids all weld positions of the cage bottom frame structure.

A positioning hole is opened on the positioning plate 515, and a positioning pin 516 is inserted into the positioning hole; a tightening rod 517 is arranged on the bottom frame fixing rod 513; the movable support plate 514 is in an L-shaped structure, and the movable support plate 514 is arranged on the long beam between the top frame fixing rod 512 and the bottom frame fixing rod 513; the lifting workbench includes a workbench and a lifting drive mechanism arranged on the left and right sides of the workbench, and two guide rails along the left and right directions are arranged under the base of the forming and welding device, and the welding base 511 of the forming and welding device is slidably connected with the guide rails.

[0061] During forming and welding, the welded top frame, bottom frame and main column are placed on the forming and welding base, and the top frame and the bottom frame are fixed with the top frame fixing rod and the bottom frame fixing rod respectively. The lifting workbench lifts the workbench to the required position, and then welding is carried out. The process of the present invention greatly shortens the welding time of the whole cage. The whole process makes the welding process safer and the production efficiency faster. The welds required to be welded in the whole cage welding stage are only about 20% of the original ones, which greatly improves the welding quality and efficiency of the whole cage and reduces the labor intensity and workload of the whole cage welding.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
