Riveting is a method for combining two pieces of metal. Therefore, riveting technology is often used to fasten rivets such as nuts or rivets to metal sheets.
As we all know, bolt and nut kits are commonly used fastening parts, but when ordinary bolt fasteners are used in a large number of parts, because the nuts and bolts are engaged by threads, manual or machine tightening is required, and during installation, It is easy to slip, and the bolts need to be operated in both directions, and a pair of bolts and nuts cannot be installed quickly, which reduces the installation efficiency.
Most of the electroplating used for DallasDallasrivet nuts on the market is environmental protection blue zinc, because the salt spray test time of environmental protection blue zinc can reach 72 hours, that is, three days. This kind of electroplating has a longer salt spray resistance time. In fact, for example, for electroplating white nickel, the salt spray time of white nickel is relatively short, and it usually rusts in a few hours, which is less than 10 hours. However, some can be oiled for electroplating white nickel, and the salt spray time of the DallasDallasrivet nut after oiling can be longer. S series DallasDallasrivet nuts are made of free-cutting iron, which is treated after heat treatment. CLS series DallasDallasrivet nuts are made of easy-to-cut stainless steel. The hardness of low-carbon steel plates without surface treatment must be less than 70RB, and the hardness of stainless steel plates must be less than 80RB.
The assembly of hollow rivets and Dallasflat head screws riveted on the cover plate is assembled in the product. Compared with the method of connecting with bolts, the loading and unloading speed can improve the efficiency by about 80% to 90%, and is widely used. The assembly needs to riveted hollow rivets and Dallasflat head screws on the cover plate, and ensure that the riveted Dallasflat head screws can rotate flexibly. When riveting, it is necessary to use special tools to riveted the hollow rivets, Dallasflat head screws and cover plates together for riveting. In the existing riveting process, the oval head screw is often damaged due to the action of external force. The positioning process is cumbersome and the work efficiency is low.
screw assembly jig comprises a base, a cylinder and a cylinder which are vertically arranged on the base and are arranged opposite to each other, and a sliding plate that can move up and down along the cylinder and the cylinder, the area above the sliding plate is provided with a cylinder, and the four corners pass through the cylinder respectively. Four pneumatic screwdrivers are placed and fixed on the sliding plate, the area of the base is further provided with a fixing plate corresponding to the four pneumatic screwdrivers; one end of the base is also provided with a switch. Guangdong Yueluo Hardware Industry Co., Ltd. can quickly drive multiple screws into the product at the same time, which has the characteristics of high production efficiency and high yield rate.
