Copper nuts are important components used in the installation of industrial production equipment, and play an important role in fastening the equipment. According to different equipment, different purposes, the choice of copper nuts may be different. Take the material of the screw-lift copper nut as an example. The material is generally lead brass. At present, most of the copper nuts sold in the market are copper alloys, and pure copper is rarely used as copper nuts. The advantage of using alloy copper nuts is that they can make up for the shortcomings of copper nuts. Material selection of copper nuts Some copper nut manufacturers or users can refer to it. First, the characteristics of ZCuSn10Pb1 material are high hardness, excellent wear resistance, not prone to seizure, good casting performance and cutting performance, and good corrosion resistance in the atmosphere and fresh water. It can be used for wear-resistant parts under high load (below 20Mpa) and high sliding speed (8m/s). Second, the characteristics of ZCuSn10Pb5 material are corrosion resistant, especially for dilute sulfuric acid, hydrochloric acid and fatty acid. Structural materials, corrosion-resistant and acid-resistant accessories, and crusher bushings and bearings. Third, ZCuSn10Pb1 has high hardness, excellent wear resistance, is not prone to seizure, has good casting performance and cutting performance, and has good corrosion resistance in the atmosphere and fresh water. Fourth, ZCuPb10Sn10 has good lubricity, wear resistance and corrosion resistance, and is suitable for bimetal casting materials. Bearings for vehicles, bimetallic bushes for internal combustion engines with a peak load of 100Mpa, as well as piston pin sleeves, friction plates, etc. Fifth, the material of ZCuZn38Mn2Pb2. It has good mechanical properties and corrosion resistance, good wear resistance, and good cutting performance.
1. Reasonably use copper and aluminum (Al) turning and milling processing tools The light knives for processing steel and copper should be strictly differentiated and used, and the margin of the light knives should be reasonable, so that the smoothness of the workpiece and the lifetime of the tool will be better. 2. Before cnc processing, first check (inspect and test) whether the tool swings within the allowable tolerance range with a calibration meter. The cutter head and lock nozzle should be blown clean with an air gun or wiped with a cloth before processing. Too dirty has a certain influence on the accuracy (precision) and quality of the workpiece (influence). 3. When clamping, pay attention to see if the name and model of the cnc processed workpiece and the program sheet are the same, whether the material (Material) size matches, whether the clamping height is high enough, and the number of calipers is used. 4. The CNC machining program sheet should be consistent with the reference angle direction marked by the mold (title: mother of industry), and then check whether the 3D drawing is correct, especially the workpiece that has been drilled and transported. Be sure to see the 3D drawing clearly Whether it is consistent with the water transport of the workpiece, if you are unclear, you should promptly report back to the programmer or find a fitter to check the 2D drawing to see if the 2D and 3D reference angles are consistent. CNC machining greatly reduces the number of tooling, and processing parts with complex shapes does not require complicated tooling. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification. 5. The program list of...
According to the relative position of the two shafts being connected, the coupling can be divided into two types: rigid coupling and flexible coupling. Rigid couplings are used where the two shafts are strictly aligned and do not occur relatively uniquely during work. The flexible coupling is used where the two shafts can have relative displacement. Rigid couplings do not have the ability to buffer and compensate for the relative displacement of the two axes, and require strict alignment of the two axes. However, this type of coupling has simple structure, low manufacturing cost, and convenient assembly and disassembly. Flexible couplings can be divided into flexible couplings without elastic elements and flexible couplings with elastic elements. The former type only has the ability to compensate for the relative displacement of the two axes, but cannot cushion the shock; the latter type is due to Containing elastic elements, in addition to the ability to compensate the relative displacement of the two axes, it also has buffering and damping effects, but the transmitted torque is limited by the strength of the elastic element. Suggest: Commonly used couplings are gear couplings, drum gear couplings, plum couplings, slider couplings, universal couplings, safety couplings, diaphragm couplings, and elastic couplings And serpentine spring coupling. It is best to select the appropriate coupling according to the specific situation, and, like this common component with high frequency, use good quality.
