Service HotlineRiveting nut tool is a special installation tool for riveting nut, including pneumatic riveting nut and electric riveting nut. Pneumatic riveting nut tool has the advantages of fast speed and large pulling force, but it is difficult to rotate into and unscrew the riveted nut. The rotating blade of the moving motor is frequently used or in a slightly dusty working environment, it will suddenly get stuck and not work, there is a great hidden danger of motor crash, and the torque of the air motor is small due to the limitation of the volume, although the riveting pulling force can be done to larger defects, but the volume also increases.
The embedded nut is made of copper nuts made of various embossed wires (usually lead brass, such as H59, 3604, 3602). The embedded knurled copper nuts that we come into contact with on a daily basis are processed by precision automatic lathes. The reference standard for embedded knurled copper nuts comes from the national standard GB/T809. The main operation method of the anti-loose nut is to inject the embedded knurled copper nut. After heating, it is embedded into the plastic part or directly injected into the mold. If the mold is injection-molded, the melting point of PA/NYLOY/PET is above 200°C , After the embedded nut is hot melted into the plastic part, the temperature rises rapidly. After injection molding, the plastic body rapidly cools and crystallizes and becomes hard. If the embedded nut temperature is still at a high temperature, it may fall to the place where the copper nut contacts the plastic part. Start to loosen or crack. Therefore, copper nuts are used instead of carbon steel nuts in the injection molding of embedded nuts. There are two ways to form the external knurling of the embedded copper nut. One is to use copper raw material to draw the knurl and then to produce it on the upper equipment. Generally, the pattern of this method is straight, and the other is to use The round copper material is directly embossed while tapping during the production process. This processing method can produce some non-standard size knurled copper nuts. The embossed shape of the embedded copper nut can be selected by the user, such as mesh, Character embossing, herringbone embossing and other knurling patterns.
The technical solution of Guangdong Yueluo Hardware Industry Co., Ltd. is: Guangdong Yueluo Hardware Industry Co., Ltd. discloses an anti-dropping nut, which includes a lock, a lock plate, a nut body, a lock ring and a lock claw. The lock ring and the nut body When used together, the lock ring is a circular ring, the inner diameter of the lock ring is larger than the inner diameter of the circumscribed circle of the nut body, the outer diameter of the lock ring is smaller than the inner diameter of the lock buckle, the lock disk is an arc-shaped metal plate, and the number of lock disks is greater than or equal to three. One short side end of the lock plate is connected to the nut body, and the other end of the lock plate is connected to the lock pawl, the lock plate is inclined to the outside of the nut body, and the lock catch is arranged on the outer side of the connection end between the lock pawl and the lock plate. On the side, the lock is a concave arc.

Gears, mechanical components with teeth on the rim that can continuously mesh to transmit motion and power, are mechanical parts with teeth that can mesh with each other. The gears used in industry are generally made of steel. The commonly used steels are quenched and tempered steel, hardened steel, carburized and quenched steel and nitrided steel. The strength of cast steel is slightly lower than that of forged steel, and it is often used in Larger-sized gears; gray cast iron has poor mechanical properties and can be used in light-load open gear transmissions; ductile iron can partially replace steel gears; plastic gears are mostly used in places where light loads and low noise are required, and are matched with them The gears are generally made of steel gears with good thermal conductivity.
