Product Details
Pin riveting is an important process in the production process. Initially, people used manual operations, which resulted in low production efficiency, high production costs, and a high rate of defective products. Later, a type of pin riveting machine emerged, which was used to rivet hardware products. The pin riveting machine was able to complete the installation and riveting of pins, The pin riveting machine reduces the process of installing and riveting pins in the hardware production process. However, its structural design is unreasonable and its operation is very inconvenient
Generally, a countersunk head is used in areas where the surface is required to be smooth without protrusions after connection, as the countersunk head can be screwed into the part. Round heads can also be screwed into the parts. The tightening force of the square head can be larger, but the size is large. In addition, in order to meet the needs of locking after installation, there are holes in the head and the rod, which can prevent the bolts from loosening when subjected to vibration. Some bolts with no threads need to be made thin, called thin waisted bolts. This type of bolt is beneficial for connection under variable forces. There are specialized high-strength bolts on the steel structure, with larger heads and varying sizes. Additionally, there are special uses for T-groove bolts, which are most commonly used on machine tools and fixtures. They have a special shape and need to be cut off on both sides of the head. Anchor bolts, used for connecting and fixing machines to the ground, come in many shapes. U-bolts, as mentioned earlier. Wait a minute. There are also specialized studs for welding, with threads on one end and no threads on the other end, which can be welded to the parts while directly tightening the nuts on the other side.
Hexagonal nuts, also known as hexagonal nuts, generally come in many types, including hexagonal nuts, round nuts, square nuts, and so on. Some standards for nuts are still quite clear. Some specifications, size standards, material requirements, electroplating standards, etc. are relatively clear. And different types of nuts also have different standards. Please provide a detailed introduction to the nut specifications and standards.
The main operation method of locking nut embedded knurled copper nut is injection molding. After heating, it is embedded into the plastic part or directly injected into the mold. If injection molding is used, the melting point of P/NYLOY/PET is above 200 ° C. After the embedded nut is hot melted into the plastic part, the temperature quickly increases. After injection molding, the plastic body quickly cools, crystallizes, and hardens. If the embedded nut temperature is still high, It is possible that the copper nut may come into contact with the plastic part and start to loosen or crack. So in the injection molding of embedded nuts, copper nuts are used instead of carbon steel nuts.
