Summary of information:We have more than ten years of experience in screw industry production, the main products are: combination set bolts, fl...

With the development of science and technology, human construction technology has also continued to improve. In terms of tools used in construction, it is constantly innovating and bringing forth new ideas, in order to enable personnel operating on construction sites to work more safely and efficiently; among them, screws The belt has become an indispensable auxiliary tool in the construction industry, especially for those who need to operate in a more dangerous high position. With the assistance of a nailing machine and a screw belt, it is quite convenient to screw together. Locked work to improve work safety and efficiency.

The existing spring pads are generally composed of longitudinal support springs, transverse connection springs, support springs, frames and frame clips. (Commonly known as string spring) is a slender and constant warp spring, used to connect the longitudinal support spring. The support spring is located at the edge of the spring pad to increase the shear resistance of the spring pad and the support strength of the frame. The surrounding frame connects the spring to the spring. up, fixed. The existing treatment method is to first heat-process the longitudinal support spring and the support spring made of 70# steel wire through the winding spring in a chemical solution, arrange them, and fix and connect them with a string spring, a frame and a clamping piece. Because the string spring and the frame have not been chemically heat treated, there is a large internal stress. Therefore, this treatment method has two disadvantages. One is that the processing efficiency of the heat treatment support spring is low. Larger, the spring is easily deformed and the service life is affected. In addition, the chemical solution after heat treatment is easy to cause environmental pollution

At present, the convex washers with traditional structures on the market have unreasonable designs and complex structures, and are inconvenient to install and disassemble. After long-term use, they are prone to fracture and deformation due to poor toughness, resulting in short service life and requiring regular downtime for maintenance, affecting assembly. The working efficiency and safety of its equipment are also poor in terms of wear resistance, corrosion resistance, and high temperature resistance. Regular replacement and maintenance also increase the economic cost of production. Therefore, the convex gasket of the existing structure can no longer meet the existing mechanical requirements. The high standard use requirements of assembly auxiliary parts are urgently needed to be solved at present.

The core rivet is another type of single-sided riveting. When riveting, the head of the rivet is hit with a hammer to expose the core, so that it is flush with the end face of the nail head, that is, the riveting operation is completed, which is very convenient, especially suitable for inconvenient Riveting occasions using ordinary rivets (which must be riveted from both sides) or blind rivets (lack of a rivet gun). Usually use flat head rivets, countersunk head rivets are suitable for occasions where smooth riveting is required on the surface.

kind of nut provided by Yueluo, the nut is in the shape of a casing and is provided with a threaded section. The two ends of the threaded section are respectively provided with two convex blocks, and the convex block at the front end of the screw-in direction reaches the hole core. The distance is greater than the nominal size of the thread segment, and the distance from the rear end projection in the screwing direction to the hole core is smaller than the nominal size of the thread segment.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: double-layer hand-tightened nuts, open washers, external hexagon flange teeth screws, set combination 304 stainless steel screws and other products, we can provide You have the right fastener solution for you.
