Description

Technical Field

[0001] The utility model relates to the technical field of bending processing, in particular to a bending forming die. Background Art

[0002] Existing bending dies usually use an integrated bending head. When bending, the bending head is seriously damaged. When the bending head is damaged, the entire bending head needs to be replaced, which is very costly. Different workpieces have different hardnesses and require bending heads of different hardnesses. In actual processing, there will be a need to process a small number of workpieces with higher hardness, and the bending head needs to be replaced, which affects the processing efficiency.

[0008] Preferably, a reinforcing block is fixedly connected to the lower end of the control panel, ear plates are provided on both sides of the reinforcing block, and the support base is slidably connected to the reinforcing block via the ear plates.

[0009] Compared with the prior art, the beneficial effects of the utility model are: a split bending head is adopted, and multiple bending heads are driven by a driving rod to bend the workpiece. When there is an error in the processed workpiece, only the damaged bending head needs to be replaced to reduce the cost; for some workpieces with smaller quantity but higher hardness, they are placed at the lower end of the reinforcement block and bent with a stronger reinforcement block.
