Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shackle forging forming, in particular to a shackle top bending equipment. BACKGROUND

[0002] In the international, the shackle production enterprises represented by the Netherlands GREENPEN, its process mainly adopts the method of steel bar two-end upsetting to form the blank, then directly bending forming, and then quenching as the final process, and the equipment has fixed and efficient die, etc. This production mode is suitable for batch production of specific products of certain specifications. Most of the shackle production in Europe is almost in this mode. France LB also adopts the final process bending forming method in the production of flat shackles, but it is almost hand production.

[0003] The shackle production mode in China is different. The shackle body in China is of special shape, and its cross section is special. Its blank is formed by bending after two-end upsetting of steel bar, and then final forging is formed by die forging. Therefore, the top bending process is only a process of blank making. This mode has low production efficiency and is more suitable for small batch or single production. Among them, the small size shackles have high efficiency in production by using flexible operation of workers. Due to the weight and other reasons, large size shackles can only be produced individually.

[0004] With the expansion of domestic production capacity demand of shackles and international competitive pressure, single production is gradually developing towards scale, and a single piece (or small batch) multi-species automatic equipment and production line system emerges as the times require. As for the top forging process, due to the differences in the shapes of D-type and B-type shackles (the D-type shackle die can be directly pulled out after top forging, while the B-type shackle must be pulled out from both sides due to the large size of the head), as well as the size difference, it is difficult for a device to adapt to both at the same time. There are positioning and extrusion errors when the workers or mechanical hands feed in the assembly line production and the die top bends, which affects the product quality.
