Service HotlineNuts are parts that tightly connect mechanical equipment. Through the inner thread, nuts and bolts of the same specification can be connected together. At present, most nuts are used together with gaskets when they are locked, or are set as an integrated structure, which has the advantage of increasing Friction, strengthen the effect of tightening, but the square nut is usually used directly without adding a gasket, and the upper and lower end faces are flat, very smooth, when subjected to strong vibration, it is very easy to loosen, and the tightening effect is not good.
Sprinkle the excess flat washer 6 on the positioning plate II3-1 on the flat washer positioning plate 3, and shake the flat washer positioning plate 3 by hand. After a short time, the flat washer 6 will be positioned and arranged on the upper positioning plate II3-1. In the flat washer hole 3-7, since the width of the opening groove 113-32 of the baffle plate II3-3 is smaller than the diameter of the flat washer hole 3-7, and the thickness of the upper positioning plate II3-1 is designed according to the thickness of the flat washer 6, each Only one flat washer 6 can be accommodated in the flat washer holes 3-7 of each upper positioning plate II3-1, and then use a brush to remove the excess flat washer
Semi-round head plastic screws have high-quality characteristics such as insulation, non-magnetic, corrosion resistance, beautiful appearance, and never rust, and modified engineering plastics, its strength and impact resistance are comparable to those of metals. The plastic screws we often say are commonly known as nylon. After adding 30% glass fiber to the screw, its mechanical properties are far superior to ordinary nylon. The materials used for the dome head plastic screws are becoming more and more diverse, the performance is constantly improving, and the application fields are becoming wider and wider. 1. Medical equipment industry (insulation, non-magnetic, environmental protection, anti-interference, make medical equipment safer to use) 2. Wind power industry (isolation and insulation of chassis circuit PCB boards) 3. Aerospace industry (electronic equipment Insulation, anti-interference) 4. Office equipment industry (never rust, beautiful and practical) 5. Petrochemical industry (high temperature resistance, chemical resistance, corrosion resistance, prolong equipment life) 6. Electronics industry (insulation, anti-interference) , light weight) 7. Communication industry (insulation, non-magnetic, safety) 8. Ship industry (acid resistance, alkali resistance, corrosion resistance, extended service life), etc... .
In order to effectively improve the working efficiency of bearing installation when the equipment or device is being installed with flat pads, it is necessary to arrange the positions of the front and back of the flat pad.エ Time-consuming, labor-intensive, low production efficiency, high processing cost defects, at the same time, there is a shortage of unstable product quality, so the development of a flat pad front identification feeding mechanism has become a hot spot of industry research.
The spring washer can prevent loosening and increase the pre-tightening force, while the flat washer does not have this function. It can be used to increase the tightening contact area, prevent the friction between the bolt and the workpiece, and protect the surface of the connector to prevent bolts. The surface of the workpiece is scratched when the nut is tightened. However, for some important connections, such as places that rely mainly on compression to generate frictional force to transmit power, spring pads cannot be used, and the rigidity of the connection is reduced, which is prone to accidents. Spring washers can be omitted. When the strength of the connected parts is low, use flat washers or flange bolts to increase the contact area. When there is vibration, pulse, and the temperature of the medium fluctuates greatly, spring washers must be used.
