Description

High-strength corner connector

Technical Field

The utility model relates to a frame construction technical field, especially the high strength connection technique of frame post roof beam.

Background

The common electric cabinet is composed of frame and door plate, the frame is formed by welding column and beam, after forming, the surface treatment process such as phosphorization and spray coating is carried out, and then the cabinet is assembled with the door.

With the development of steel technology, steel plates with an anti-corrosion function (such as aluminum-zinc plated plates) are directly processed by steel manufacturers and delivered from factories, and are subsequently processed and applied, and if a welding procedure is not adopted, surface treatment processes such as phosphorization and spraying which pollute the environment are not needed. In order to reduce pollution damage to the ecological environment, welding procedures are not adopted as much as possible, the existing cabinet frame is basically formed by assembling, the joint connection of frame beam-column assembly is usually realized by corner connectors, the strength and the shape of the corner connectors directly influence the overall strength of the frame, the convenience of assembly and the assembly cost, the shape of the corner connectors determines the forming process, and the cost of corner connectors is also determined.

Common corner connectors are of the types of profiles, sheet metals, die castings and the like.

For example, the corner brace is similar to the corner brace of the section type related to the invention patent with the application number of 202011353890.6 or the corner brace of the sheet metal type related to the appearance design patent with the application number of 202030664971.2, has simple shape, but the moment for resisting the angular deformation of the two mounting surfaces is insufficient, and the corner brace can only be used for occasions with low requirement on the connection strength.

In addition, similar to the die casting corner connectors related to the utility model with application number 201720099427.0, although the connection with certain strength can be realized, the shape is special, and the production of a customized die is needed, so that the cost is high.

And the corner connectors of the section types related to the patents with the application numbers of 202020451883.9, 201720719559.9, 201821079406.3, 201821048814.2, 201320373117.5 and the like are all manufactured by a customized die, and have complex shapes and higher cost.

Disclosure of Invention

To the problem, the utility model provides a high strength angle sign indicating number, joint strength is high, and the shaping precision is high, and is with low costs.

In order to realize high strength connection, the angle sign indicating number has increased upper and lower pterygoid lamina on the basis of common L shape angle sign indicating number, has the entity with adjacent web to be connected, has increased the anti deformation moment of angle sign indicating number, therefore joint strength is high.

First web 2, second web 4, the third web 6 of angle sign indicating number are independent each other, but its installation face is the coplanar, with the back of same installation body connection, have formed the connection effect of whole web.

Angle sign indicating number adds man-hour bending, adopts the former limit of numerical control unloading to fix a position, and the position of bending is accurate, therefore the shaping precision is high.

The angle sign indicating number is a sheet metal part that the steel sheet was taken shape through cutting unloading, bending, and its panel beating expandes the shape and has certain complementarity when the ingredient, has improved the utilization ratio of material, therefore has reduced material cost. The part processing process only needs two procedures of blanking and bending, and a welding process is not needed, so that the processing cost is low, and surface treatment is not needed after processing, thereby realizing the overall low cost of the part.

The angle sign indicating number seems the shape complicacy, has 5 to bend, really only needs 3 times the shaping of bending, and processing is simple, consume man-hour weak point, has characteristics such as with low costs, intensity height, the engineering implementation of being convenient for.

Detailed Description

With reference to the above drawings, the specific implementation of the corner brace of the present invention is described as follows:

the steel plate is cut and blanked by the numerical control cutting equipment to form a semi-finished product of the part shown in figure 2, all mounting holes of the corner connectors are also finished in the cutting and blanking process, a drilling process is not needed, and the machining efficiency is high. The numerical control machining has the characteristic of high precision, the shape and position errors of the

cut edges

18, 19, 20, 21 and 22 in the drawing are extremely small, and the cut edges can be used as positioning edges during bending forming so as to ensure high bending forming precision and further ensure high positioning precision of mounting holes after corner brace forming.
