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,...
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...
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...
Copper pipes are lighter in weight, have good thermal conductivity and high strength at low temperatures. Often used in the manufacture of heat exchange equipment. It is also used to assemble cryogenic pipelines in oxygen production equipment. Copper pipes with small diameters are often used to transport pressured liquids (such as lubrication systems, oil pressure systems, etc.) and pressure measuring tubes for instruments. Copper pipes are strong and corrosion resistant, and they have become the choice of modern contractors for the installation of water pipes, heating and cooling pipes in all residential commercial buildings. 1. Because the copper pipe is easy to process and connect, it can save material and total cost during installation, has good stability and reliability, and can save maintenance. 2. Copper is lightweight. For twisted threaded pipes of the same inner diameter, copper pipes do not require the thickness of ferrous metal. When installed, the transportation cost of the copper pipe is smaller, the maintenance is easier, and the space is smaller. 3. Copper can change its shape. Because copper pipes can be bent and deformed,...
As the role of machinery in various industries has become more prominent, the importance of gears has become more obvious. As the role of machinery in various industries has become more prominent, the importance of gears has become more obvious. As you all know, many machines need to use gears, and they need to be equipped with suitable gears to keep the machine working. The processing of gears may be a bit more difficult than machinery, so you should not ignore the value of gears. When designing gear shafts, they are generally used as four aspects. 1. The gear shaft is generally a pinion (a gear with a small number of teeth). 2, the gear shaft is generally in the high-speed stage (that is, the bottom torque stage). 3. Gear shafts are generally seldom used as sliding gears for shifting speeds. They are generally fixed-running gears. First, because they are in the high-speed stage, their high speeds are not suitable for sliding shifting. 4. The gear shaft is a combination of shaft and gear, but in the design, the length...
If we know the direction of rotation of the worm and worm wheel, if we want to judge the direction of rotation of the worm, we need to stretch out the right or left hand, half-make a fist, and make the thumb point to the opposite direction of the linear velocity direction of the worm gear meshing point. The direction of the remaining four fingers is the same as the worm rotation direction, the worm should be right-handed, if it is the same as the left hand, the worm should be left-handed. The rotation and direction of rotation of the worm are often known. The method to determine the direction of rotation of the worm is: when the worm is right-handed, extend your right hand, half-make a fist, and point to the direction of rotation of the worm with the remaining four fingers except the thumb At this time, the direction opposite to that of the thumb is the linear velocity direction of the worm wheel at the meshing point, so that the direction of rotation of the worm wheel...
