The third die body 3 is arranged on the first die body 1, the third die body 3 actually forms a finished stamping surface with the first die body 1 and the second die body 2 at the moment, and when the second matching surface 202 is tightly attached to the inner wall surface of the flange, the third die body 3 is also abutted to the outer wall surface of the flange, so that the third die body 3 can be matched with the second matching surface 202 and the surface of the first die body 1 at the same time, and the straight edge of a workpiece is stamped into the flange.

However, since a gap is formed between the third die body 3 and the second mating surface 202, it should be noted that the gap is an abstract form, and in fact, no gap exists between the third die body 3 and the second mating surface 202, and then due to the current technological level or the manufacturing level of the die itself, the surface tolerance of the punched flange inevitably exists, and the flange of the workpiece is rebounded. Therefore, in order to avoid the problem, the third die body 3 can move a smaller stroke in the horizontal direction relative to the first die body 1, and the third die body 3 can selectively support the flanging to be tightly matched with the second matching surface 202, so that the wedge mechanism can be conveniently adjusted in the process of convenient debugging, and the rebound and surface tolerance of parts can be effectively solved.

The second embodiment of the present invention, which enables the third casing 3 to move in the horizontal direction and to be engaged with the second casing 2, is achieved by the following means.
