Service HotlineAt present, the standard parts on the market mainly include carbon steel, stainless steel and copper. A carbon steel. We distinguish low carbon steel, medium carbon steel and high carbon steel and alloy steel by the content of carbon in carbon steel material. 1 Low carbon steel C%≤0.25% is usually called A3 steel in China. Foreign countries are basically called 1008, 1015, 1018, 1022, etc. Mainly used for grade 4.8 bolts, grade 4 nuts, small screws and other products without hardness requirements. (Note: 1022 material is mainly used for drill tail screws.) 2 Medium carbon steel 0.25% 3 High carbon steel C%>0.45%. 4 Alloy steel is basically not used in the market: alloying elements are added to ordinary carbon steel to increase some special properties of steel: such as 35, 40 chromium molybdenum, SCM435, 10B38. Fangsheng screws mainly use SCM435 chromium molybdenum alloy steel, the main components are C, Si, Mn, P, S, Cr, Mo. Two stainless steel. Performance grade: 45, 50, 60, 70, 80 1 Mainly divided into austenite (18% Cr, 8% Ni) with good heat resistance, good corrosion resistance and good weldability. A1, A2, A4 2 Martensite, 13%Cr have poor corrosion resistance, high strength and good wear resistance. C1, C2, C4 ferritic stainless steels. 18%Cr has better upsetting and corrosion resistance than martensite. The imported materials on the market are mainly Japan. According to the level, it is mainly divided into SUS302, SUS304 and SUS316. Three coppers. Commonly used materials are brass...zinc-copper alloys. The market mainly uses H62, H65, H68 copper as standard parts.
At present, due to the installation position determined in the design process of the traditional thrust cylinder in China, the corresponding position of the piston rod and the clamping arm is fixed, and it is impossible to ensure that the workpiece can be clamped while the workpiece is thin. It is not conducive to the use of such products when clamping. Secondly, when the workpiece is assembled or welded, it not only needs to be tightened in a certain direction, but also needs to be positioned, so as to ensure the accuracy required for processing. When a workpiece is fixed in this way, it must be realized by adding a mechanism, which will increase the complexity of the system and bring inconvenience to installation and maintenance.
The production process of rivet nuts is basically similar to that of other screws. It's just that the screws are punched out with a screw pier, and the nuts are punched out with a nut pier. Introduce the production process of rivet nuts. 1. First, it is necessary to determine what material and material the rivet nut is, so that we can use what material to produce and what material to use. Knowing what materials and materials are used, we can buy screw wires. 2. Determine the size and length of the rivet nut. This is the best way to use a large screw wire. 3. After determining the material, material, size and type, we need to see if it is a commonly used rivet nut. If so, there must be a corresponding mold in the factory. If not, it is non-standard, then we have to order molds. 4. After everything is ready for production, it is necessary to use the nut machine to punch out the shape of the rivet nut, that is, the appearance. 5. After the pier is punched out, use the machine for tapping the nut teeth to tap it. 6. After the thread is tapped, electroplating is performed. The stainless steel rivet nut does not need electroplating, it only needs to be cleaned. If you want to electroplate other colors, you have to take it to a professional electroplating manufacturer for electroplating treatment.
Some electronic products need to install some plastic parts or protective sleeves for components on the PCB, which need to be fixed by screws. The function of the fixture is to locate the PCB and the required installation parts, and increase the work efficiency. The existing screw fixture is inconvenient According to the needs of the site, the positioning station of the screw can be changed, the accurate positioning of the screw is difficult and the clamping effect of the workpiece is poor. A screw jig is proposed.
In order to meet the requirements of anti-loosening bolts of parts with small surface hardness such as plastic parts, Yueluo provides a spring washer and the installation structure of the spring washer, which can effectively reduce the damage of the spring washer to the surface of the parts. And meet the anti-loosening effect of the spring washer. The technical solution provided by Yueluo is a spring washer, which includes a washer body with at least two raised claws on the washer body
