In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.
[0018] High-strength sheet metal parts, such as Figure 1 , Figure 2 as well as Figure 3As shown, it includes a first sheet metal plate 1 and a second sheet metal plate 2. Taking the angle of the first sheet metal plate 1 and the second sheet metal plate 2 after splicing as 90 degrees as an example, the second sheet metal plate 2 is formed with a through groove by continuous bending, and the first sheet metal plate 1 is formed with a fitting portion that is slidably inserted into the through groove along the side position of the through groove. The second sheet metal plate 2 is bent on both sides of the first sheet metal plate 1 to form a first abutting portion 21 and a second abutting portion 22 with a U-shaped structure. The bottom surfaces of the first abutting portion 21 and the second abutting portion 22 are relatively fitted to the side surface of the first sheet metal plate 1. In this specific embodiment, the maximum width of the first abutting portion 21 and the second abutting portion 22 is equal to three times the thickness of the second sheet metal plate 2, and the maximum thickness of the inner side of the first abutting portion 21 is equal to the thickness of the second sheet metal plate 2.
[0019] The first abutment portion 21, the second abutment portion 22 and the embedded portion 11 are pre-bent during production. During splicing, after the first sheet metal plate 1 and the second sheet metal plate 2 are inserted, a bending machine is used to apply a force to bend the first abutment portion 21 and the second abutment portion 22 from top to bottom in the direction of the through groove, and then glue is squeezed into the positions where the first abutment portion 21 and the second abutment portion 22 are attached to the first sheet metal plate 1. When there is no large-scale equipment for construction on site, the position of the second abutment portion 22 can also be bent as a whole by using pliers such as pliers, and the position of the first abutment portion 21 is not processed, or after the second sheet metal plate 2 is placed on a plane, both sides of the first abutment portion 21 are bent.
[0020] Practical effect: Compared with the prior art, the first sheet metal plate 1 is not prone to swinging through the support of the first abutting portion 21 and the second abutting portion 22, thereby ensuring the stability of the injection structure.
[0021] like Figure 1 , Figure 2 as well as Figure 3 As shown, further, the cross section of the through groove is an inverted T-shaped structure, the fitting portion includes an embedded portion 11 in a U-shaped structure and a support portion 12 integrally formed on one side of the embedded portion 11, the embedded portion 11 and the two sides of the support portion 12 that are far away from each other are arranged at intervals from the inner wall of the through groove, the second abutting portion 22 and the embedded portion 11 can be bent toward the direction of the through groove at the same time to close, and when the first abutting portion 21 is bent toward the direction of the through groove to close, the support portion 12 supports the through groove to fit the position of one side of the first abutting portion 21;
[0022] Furthermore, in order to make the on-site press bending operation more convenient, the second sheet metal plate 2 is formed with a plurality of first punching holes 23 along the first abutting portion 21 toward the through groove, and the first sheet metal plate 1 is formed with a plurality of second punching holes 13. A group of first punching holes 23 and a group of second punching holes 13 can pass through the rivets that push the second sheet metal plate 2 toward the inner side to clamp the embedded portion 11. Specifically, the rivets can be installed by pull riveting.
