Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sheet metal layers, and in particular relates to a welding-free sheet metal bending structure. Background Art
[0002] Some shelves and workbenches for storage use shelf boards. Generally, shelf boards are sheet metal parts. Since shelf boards usually have bending structures, the existing processing steps are cutting, bending, welding, grinding and spraying. Since welding is required, bending must be performed first, which consumes more energy. Grinding is also required after welding, and the connecting grinding process line greatly increases the process cost and labor cost, resulting in high input and low output in terms of production time and finished product control. In addition, since the bending is before spraying, it is not easy to apply powder on the grooves and dead corners of the bend after electrostatic spraying, and uneven spraying affects the appearance and may cause rust. Utility Model Content
[0003] The purpose of the utility model is to provide a welding-free sheet metal bending structure, including a sheet metal plate body, wherein the first bending part and the second bending part are formed by bending at both sides of the lower part of the sheet metal plate body respectively, the first bending part and the second bending part are plugged and positioned, a positioning hole is provided on the first bending part, and a positioning block is formed by bending on the second bending part, the first bending part is arranged on the inner side of the second bending part, and is plugged and matched with the positioning block and the positioning groove.
[0004] In the present invention, a further implementation scheme is that the first bending portion and the second bending portion are both bent 90° relative to the sheet metal plate body.
[0005] In the present invention, a further implementation scheme is that the cross section of the first bending portion is in a right-angle hook shape.
[0006] In the present invention, a further implementation scheme is that the cross section of the second bending portion is L-shaped.
[0007] In the present invention, a further implementation scheme is that the positioning block is bent and formed on both sides of the second bending portion.
[0008] In the present invention, a further implementation scheme is that a connecting groove is also provided on the second bending portion for matching with a column for locking and fixing.
[0009] The beneficial effects of the utility model are:
[0010] The first bending part and the second bending part on the main body of the sheet metal plate are bent by a seamless bending knife. Therefore, on the basis of maintaining the original strength, they are formed only by bending, and do not require welding or grinding processes. The process is reduced to cutting, spraying and bending, which reduces the number of processes, saves material costs, process costs and labor costs, and improves output efficiency to a certain extent. Moreover, spraying can be performed first and then bending, so that the entire layer can be evenly powdered and sprayed in place, improving the aesthetics and spraying quality.

For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0015] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0016] It should be noted that, in the description of the present application, the orientation or positional relationship indicated by terms such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise stated, these orientation words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present application; the orientation words "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0018] like Figure 1 The utility model provides a welding-free sheet metal bending structure, comprising a sheet metal plate body 1, wherein two sides of the lower part of the sheet metal plate body 1 are respectively formed into a first bending portion 10 and a second bending portion 11 by bending.
