Service HotlineThe inner hole retaining ring groove processing mechanism is characterized in that: it comprises a pneumatic grinder fixed block installed on the tool table of the lathe, a pneumatic grinder installed on the pneumatic grinder fixed block and a grinding wheel piece installed on the front end of the pneumatic grinder; The pneumatic grinder mounting block is provided with a pneumatic grinder installation through hole, and there are at least 2 screw holes above the pneumatic grinder installation through hole; the grinding wheel is designed according to the diameter of the product and the thickness of the groove width, in order to increase the strength of the grinding wheel , Add flanges at both ends of the grinding wheel to improve the strength of the grinding wheel. The grinding wheel piece includes the connecting blade on the flange plate. The center of the flange plate is provided with a mounting hole installed on the pen-type pneumatic grinder. The diameter of the mounting hole is 17.8- 18mm, the diameter of the grinding wheel is 18-20mm.
The rivet nut is a kind of nut applied to thin plate or sheet metal. The principle is to press the embossed teeth into the preset holes of the sheet metal. Generally, the diameter of the square preset holes is slightly smaller than the embossed teeth of the pressure riveting nut. The periphery of the hole is plastically deformed, and the deformed object is squeezed into the guide groove, thereby producing a locking effect. The pressure riveting nut is divided into free-cutting steel pressure riveting nut S type, stainless steel pressure riveting nut type CLS, stainless iron pressure riveting nut SP type and copper and aluminum pressure riveting nut CLA type, which should be used in different environments. . Generally speaking, the national standard domestic products without rivet nuts from M2 to M12 are PEM specifications, which are usually produced in chassis cabinets and sheet metal industries.
Principles of stainless steel screw material selection: The selection of stainless steel materials is mainly considered from the following five aspects. 1. Requirements on mechanical properties, especially strength, of stainless steel screw materials; 2. Requirements on corrosion resistance of materials by working conditions; 3. Heat resistance of materials by working temperature (high temperature strength, oxidation resistance) 4. Requirements for material processing performance in terms of production technology; 5. Other aspects such as weight, price, procurement and many other factors must be considered.
The rivet nuts are divided into S series, CLS series and SP series. It provides a simple method for installing internal threads on precision metal sheet products, and plays a reliable fixing role. The small and delicate nut enables the plate to be embedded and processed on one side. When installing, just insert the nut into the hole of the metal plate. , to complete the setting firm function with pressure. When choosing to buy a rivet nut, you only need to provide a few elements: 1. Installation thickness 2. Internal thread size 3. What height do you require the nut to protrude from.
self-locking nut is a nut that can self-lock by friction. The general nut will loosen itself due to vibration and other reasons during use. In order to prevent this phenomenon, the self-locking nut was invented. The main functions of self-locking nuts are anti-loose and anti-vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with nylon rings, those with neck closures, and those with metal anti-loosening devices. They are all effective torque type lock nuts (see GB/T3098.9-2002 national standard).
