[0017] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0018] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0019] Reference Figure 2-4An embodiment of the utility model provides a sheet metal stretching die, comprising: a lower die 1, an upper die 2, a punch 3 and a die 4, the upper surface of the lower die 1 is a V-shaped concave structure, the lower surface of the upper die 2 is a V-shaped convex structure, a lower stretching groove 5 is arranged in the middle of the lower die 1, an upper stretching groove 6 corresponding to the lower stretching groove 5 is arranged in the middle of the upper die 2, the punch 3 is telescopically installed in the lower stretching groove 5 of the lower die 1, the die 4 is telescopically installed in the upper stretching groove 6 of the upper die 2, the upper surface of the punch 3 is a V-shaped concave structure, and the lower surface of the die 4 is a V-shaped concave structure.

[0020] In the above technical scheme, a V-shaped upper die 2 and a lower die 1 are provided, and the upper stretching groove 6 of the upper die 2 and the lower stretching groove 5 of the lower die 1 are telescopically installed with a V-shaped die 4 and a punch 3 respectively; when working, the V-shaped sheet metal is placed on the upper surface of the lower die 1, the upper die 2 is started to move downward until the lower surface of the upper die 2 is attached to the upper surface of the sheet metal, the punch 3 and the die 4 are started, and both move upward synchronously to stretch the sheet metal, thereby completing the stretching preparation work of the product; the utility model can quickly prepare the product by stretching, effectively reduce the production process, improve the production efficiency, and reduce the production cost.
