[0018] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0019] The following specific examples illustrate the implementation manners of the present disclosure. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of them. The present disclosure can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present disclosure belong to the scope of protection of the present disclosure.

[0020] Refer to Figures 3 - 5, an embodiment of the present utility model provides a rapid 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 folded surface structure composed of a plane and an inclined plane. The lower surface of the upper die 2 is a folded surface structure composed of a plane and an inclined plane. The upper surface of the lower die 1 corresponds to the lower surface of the upper die. A lower stretching groove 5 is provided in the middle of the lower die 1, and an upper stretching groove 6 corresponding to the lower stretching groove 5 is provided 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, and 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 stepped structure, and the lower surface of the die 4 is a stepped structure. The upper surface of the punch 3 corresponds to the lower surface of the die 4.

[0021] In the above technical solution, by providing an upper die and a lower die with a folded surface structure, and a stepped die and punch are respectively telescopically installed in the upper stretching groove and the lower stretching groove of the upper die and the lower die. During operation, a plate-shaped sheet metal part with a folded surface structure is correspondingly 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 part. The punch 3 and the die 4 are started, and the two move upward synchronously to stretch the sheet metal part, completing the stretching preparation work of the product. This enables the present utility model to rapidly stretch and prepare the product, effectively reducing the production process, improving the production efficiency, and reducing the production cost.

[0022] In some embodiments, the lateral inner contour of the lower stretching groove 5 matches the lateral outer contour of the punch 3; the lateral inner contour of the upper stretching groove 6 matches the lateral outer contour of the die 4. This structural design enables the punch 3 and the die 4 to better stretch the sheet metal part and prevent wrinkling.

[0023] In some embodiments, concave or convex patterns are distributed on the surface of the punch 3, and corresponding convex or concave patterns are distributed on the surface of the die 4. This structural design enables the surface of the product prepared by stretching with the die of the present utility model to form the required concave and convex patterns.
