Service HotlineToday's advanced manufacturing represented by large aircraft, large power generation equipment, automobiles, high-speed trains, large ships, and large complete sets of equipment has entered an important development direction. As a result, fasteners will enter an important stage of development. High-strength bolts are used for the connection of important machinery, and repeated disassembly or various installation torque methods require extremely high-strength bolts. Therefore, the quality of its surface condition and thread accuracy will directly affect the service life and safety of the host. In order to improve the friction coefficient and avoid corrosion, seizure or sticking during use, the technical requirements stipulate that the surface should be treated with nickel phosphorus plating. The thickness of the coating is guaranteed to be within the range of 0.02 to 0.03 mm, and the coating is uniform, dense, and free of pinholes.
The retaining ring is a ring-shaped body with an opening, and the traditional processing method is stamping. That is, a plate-shaped material is selected and punched out on the plate-shaped material (a circular body, and then the middle of the circular body is punched to form a ring-shaped ring body.) The punched material in the middle cannot be used again. This results in a waste of material.
An anti-falling nut, comprising a lock buckle 1, a lock plate 2, a nut body 3, a lock ring 4 and a lock claw 5, the lock ring 4 and the nut body 3 are used together, the lock ring 4 is a circular ring, and the lock ring 4 is a ring. The inner diameter of the ring 4 is larger than the inner diameter of the circumscribed circle of the nut body 3, the outer diameter of the lock ring 4 is smaller than the inner diameter of the lock 1, the lock plate 2 is an arc-shaped metal plate, and the number of the lock plates 2 is greater than or equal to three. One end of the short side is connected to the nut body 3, the other end of the lock plate 2 is connected to the lock pawl 5, the lock plate 2 is inclined to the outside of the nut body 3, and the lock buckle 1 is provided at the connection end of the lock pawl 5 and the lock plate 2. The outer side of the lock buckle 1 is a concave arc.
At present, the known automatic nail feeding screws are composed of the traditional hand-held electric drill modified electric screw and the automatic nail feeding device, in which the screw head cannot be moved and the angle can be changed. It is difficult to complete the installation due to the obstruction, so a multi-directional screw with a movable and rotatable screw head is required.
Standard screw is one of the fasteners commonly used for fastening and assembly. Standard screws and flat washers, grade A, and standard spring washers, are used in combination, and are widely used in the assembly of various products. For manufacturers who use combination screws in small and medium batches, the process of combining screws, spring washers and flat washers generally adopts the method of assembling screws by workers' bare hands. This method is tedious and repetitive, wastes human resources, is time-consuming and labor-intensive, and it is difficult to ensure the normal operation of the workshop. assembly progress. The screw assembly machines currently on the market can replace manual assembly screws, but this type of equipment has disadvantages such as bulky size, high cost, complex structure, inconvenient non-standard manufacturing and maintenance, high noise, and power consumption.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: three-piece expansion pipe bolts, galvanized/color-plated square nuts, processing and production of machine screws, slanted flat head hexagon socket nuts and other products, we can Provide you with the right fastener solution for you.
