In this embodiment, a plurality of positioning holes 102 are formed in the casing 1, a plurality of protruding columns 201 corresponding to the plurality of positioning holes 102 one to one are integrally formed at the top of the lower die 2, when the casing 1 is placed on the lower die 2, the plurality of protruding columns 201 are inserted into the plurality of positioning holes 102 one to one, positioning of the casing 1 is achieved, four edges of the casing 1 after positioning extend to the outer side of the top surface of the lower die 2, and therefore when four upper dies move downwards, four inner side surfaces of the opening can be corresponding to four side edges of the punching casing 1 one to one. Notches 103 (as shown in fig. 2 and not shown in fig. 1) are symmetrically formed on two sides of the housing 1 adjacent to the round 101, so that the round 101 will not deform during the forming process.

In this embodiment, the sliding die 6 is slidably disposed in a horizontal direction, so that the sliding die 6 can slide toward the center of the opening, because the lower die 2 is slidably disposed through the compression spring 13, after the four sides of the housing 1 are punched to form a vertical shape, the opening continues to move downward to drive the compression spring 13 to generate compression deformation, so that the lower die 2 moves downward, and the lower die 2 and the opening (i.e., the four upper dies) move downward synchronously, so that the distance between the lower die 2 and the sliding die 6 in height is kept unchanged, and preparation is made for punching one of the vertical sides of the sliding die 6 to form a circle, and the sliding die 6 is driven to slide toward the center of the opening in the downward movement process of the lower die 2, so as to change the shape of a gap between one inner side of the opening and one outer side of the lower die 2, so as to punch one vertical side corresponding to form the circle 101, thereby realizing the manufacturing of the housing 1. The working principle of the die provided by the invention is as follows: firstly, placing a shell 1 provided with a plurality of positioning holes 102 on the top of a lower die 2, inserting a plurality of protruding columns 201 into the plurality of positioning holes 102 in a one-to-one correspondence manner to realize positioning of the shell 1, then starting a driving mechanism to enable four upper dies to move downwards simultaneously (namely to move towards the lower die 2), enabling the four upper dies to move downwards simultaneously, namely to move downwards of an opening, enabling the shell 1 to be continuously close to the bottom of the opening along with continuous downwards movement of the opening until four sides of the shell 1 are respectively abutted with the bottom edges of four inner sides of the opening, then enabling the four sides of the shell 1 to be punched into gaps formed between the four inner sides of the opening and the four outer sides of the lower die 2, enabling the width of the gaps to be equal to the thickness of the four sides of the shell 1 at the moment, and enabling the four sides of the shell 1 to form a vertical shape; in the latter half of the movement of the opening toward the lower die 2, the opening continues to move downward so that the lower die 2 and the housing 1 move downward simultaneously, at this time, the sliding die 6 is driven and slid toward the center of the opening to punch one vertical side corresponding thereto to form a turn 101, thereby forming a product in which the housing 1 and the turn are integrally formed. In the prior art, the existing set of dies cannot be utilized to punch out the integrally formed turning circle on the basis of punching out the vertical side edge, the vertical side edge of the C shell is generally punched out through one set of dies, then the turning circle is independently manufactured through the other set of dies, and finally the turning circle is mounted on the C shell, so that the integral forming of the C shell and the turning circle cannot be realized, the assembling operation between the C shell and the turning circle can be increased, and the complexity of computer assembling is improved.

By improving the structures of the upper die and the lower die, the invention can not only punch the four sides of the metal shell 1 (and the C shell) into a vertical shape in the downward punching process of the upper die, but also punch one of the vertical sides to form the round 101, thereby realizing the integral forming of the metal shell 1 and the round 101, avoiding the separate manufacturing of the C shell and the round, avoiding the assembly operation between the C shell and the round, overcoming the technical defect that the integral forming of the metal C shell and the round is unavailable in the prior art, and effectively solving the defects in the prior art;

meanwhile, because the stamping directions of the shell 1 are different when the vertical side edges are formed and the round is formed, one set of dies in the prior art cannot realize stamping actions in different directions at the same time, and further cannot realize perfect fit of forming the round on one of the vertical side edges after the four vertical side edges are formed firstly for the shell 1 in the present application, and the invention can complete all operations of forming the vertical side edges of the shell 1 and forming the round on one of the vertical side edges by one set of dies through one technical improvement and creative stamping, and the fit degree is perfect fit, so that unexpected technical effects are generated, namely the number of dies is saved, the beneficial effects of improving the resource utilization rate are improved, the manufacturing time of the shell 1 is greatly reduced, the manufacturing efficiency of the shell 1 is improved, and the invention has remarkable progress compared with the prior art.
