Preferably, the upper left corner of the side push block is provided with a first lower inclined surface matched with the first upper inclined surface at the lower right corner of the driving slotting tool.

Preferably, the swing block leaning knife is provided with a second lower inclined surface matched with the second upper inclined surface at the lower right corner of the swing block.

Preferably, a limiting plate matched with the swinging block by a cutter is arranged on the lower die base, and a nitrogen spring is arranged between the limiting plate and the lower die base.

Compared with the prior art, the beneficial effects of the utility model are that:

due to the adoption of the structural design, the slotting tool is driven to drive the side pushing block to move rightwards, the side pushing block drives the swinging block to move rightwards, the free end of the swinging block moves upwards under the action of the swinging block close to the tool and is matched with the bending punch to realize the bending operation, the process is easy to form, and the die manufacturing cost is low.
