The riveting positioning block includes a positioning pin and a rivet yielding hole, a through hole is arranged in the center of the riveting positioning block, a rivet hole is arranged on one side of the through hole, and a number of positioning pins are arranged on the riveting positioning block around the through hole. . There are five positioning pins. The riveting lower die includes a countersunk head screw hole, a rivet guide block and a positioning hole. The riveting lower die is a stepped module. The left side of the riveting lower die is provided with a countersunk head screw hole, and the right side of the riveting lower die is provided with a countersunk head screw hole. The guide block is provided with several positioning holes on the riveting lower die located in front of the guide block. There are two positioning holes. The center of the guide block is provided with an escape hole. Compared with the existing technology, Guangdong Yueluo Hardware Industry Co., Ltd. has a rivet-oriented positioning riveting tooling. The rivets are placed on the tooling, and then placed in the riveting machine together with the product for riveting, which solves the problem of manual knock-in. The efficiency is low, and the riveting can be riveted without deviation without manual righting during riveting, so that the quality of the products produced is the same, the scrap rate is reduced, and the production efficiency is greatly improved.
As we all know, screws and nuts are widely used in various mechanical equipment as connectors, so that the mechanical equipment can be easily disassembled, but for equipment whose internal structure needs to be kept secret, it generally does not need to be disassembled after assembly. The nut can be easily dismantled, leaving equipment that needs to be kept secret of the internal structure from being kept secret.
Further, the pressure riveting portion and the pressure-bearing portion are both columnar structures, the outer diameter of the pressure-bearing portion is larger than the outer diameter of the pressure riveting portion, the pressure riveting portion is a stepped structure, and the diameter of the lower end of the pressure riveting portion is smaller than that of the pressure riveting portion. The diameter of the upper end of the rivet part.
As one of the screws, self-tapping screws can directly drill holes on the plate to be fixed by themselves and lock them together with the plate to be fixed. They are easy to use and have a good fixing effect, so they are widely used. However, in the prior art, when the screw is perforated on the plate to be fixed, it is prone to skew, which affects the fixing effect and also reduces the aesthetics. To sum up, how to overcome the above-mentioned defects of the screw fixing method in the prior art is a technical problem to be solved urgently by those skilled in the art.
through-hole mounting nut, comprising a hexagonal portion 1 and a cylindrical portion 2, a threaded hole 3 is provided between the hexagonal portion 1 and the cylindrical portion 2, and two grooves 4 are opened on the cylindrical portion 2, and each of the two sides of the groove 4 has a The raised side 5, the two sides protruding from the sheet metal part 7, if squeezed or hit by the bolt 8, it will bend to both sides and buckle on the sheet metal part, so that it is not welded directly. Rubber can also be used. Each of the upper surfaces of the side edges 5 is provided with a convex point 6 so that the hammer will not slip when hitting.
