Service HotlineThe existing combination screws and accessories are individually processed and then handed over to the customer for assembly. This method is prone to assembly problems, and the combination screws and accessories need to be marked with identification marks, which increases the production cost.
Screws are very small screws used for indispensable industrial necessities in daily life, such as cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; large screws are used for engineering, construction, and bridges; Transportation equipment, airplanes, trams, automobiles, etc. use large and small screws together. At present, in the machine assembly production line, when the flat washers, spring washers and screws are matched during the screw assembly process, the flat washers, spring washers and screws are easy to fall into the product due to their small size, resulting in low screw matching efficiency. If there are flat washers, spring washers, screws, etc. that fall into the product and are not found in time and left inside the product, it may cause damage to the machine structure, and even cause casualties in serious cases.
Therefore, in order to obtain fasteners that meet the requirements, it is usually necessary to anneal the middle sections of bolts, rivets, etc. to reduce the hardness of the middle sections, while ensuring the hardness of the heads of bolts, rivets, etc. At present, the existing process adopts ultra-high frequency induction heating equipment to instantly heat the middle section and reduce the hardness. However, this process requires a lot of control, and the heating time is slightly longer, which affects the hardness of the head, and the mass production is very unstable, which is easy to cause the rivet to fail. At the same time, the cost of ultra-high frequency equipment is high and the power consumption is large, which is not conducive to mass production and energy saving. Environmental friendly.
High-strength self-locking nuts are a category of self-locking nuts with high strength and reliability. It is mainly based on the introduction of European technology, which is used for road construction machinery, mining machinery, vibration machinery and equipment, etc. There are very few domestic manufacturers of such products.
rivet is a nail-shaped object used to join two parts or components with a through hole and a cap on one end. In riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are not limited to the form. The existing switch is not easy to fix, and needs to be supported by others during installation, which leads to waste of labor, and at the same time, it is easy to damage the hands of the supporting personnel. The existing device driving method is relatively laborious. Some devices require rivets of different lengths in different thicknesses, and cannot be assembled by themselves of the same type.
