Which Dongguan gasket is better? I recommend the daily production capacity of hardware 3000000 times stamping

The washer is the part between the connected piece and the nut. Generally, a flat metal ring is used to protect the surface of the connected part from being scratched by the nut and disperse the pressure of the nut on the connected part. So what are the commonly used types of washers? What are the functions of the washers? What are the commonly used types of washers? Washers are divided into: flat washers-C level, large washers-A and C levels, extra large washers-C level, small washers-A level, Flat washers-Grade A, flat washers-chamfered-grade A, high-strength washers for steel structures, spherical washers, tapered washers, square bevel washers for I-beams, square bevel washers for channel steel, standard spring washers, Light spring washer, heavy spring washer, internal tooth lock washer, internal serrated lock washer, external tooth lock washer, external serrated lock washer, single lug stop washer, double lug stop washer, outer tongue stop washer, Stop washers for round nuts. The function of the washer-spring washer (spring) washer, circlip is a resilient cushion or a lock washer that prevents bolts from loosening. The working principle of the lock washer is very simple. It consists of two washers. The outer side is a radial convex surface, and the inner side is a helical tooth surface. When assembling, the inner helical tooth surfaces are opposed to each other, and the outer radial convex surface is in occlusal state with the contact surfaces at both ends. When the connecting piece is vibrated and the bolt tends to loosen, only the inner helical tooth surfaces of the two washers are allowed to face each other. Mismovement generates lifting tension, so as to achieve 100% locking. The function of the spring washer is to prevent loosening, that is, to prevent the nut from loosening. It is generally used in structures with small impact loads or less important anti-loose structures or structures and occasions where the loosening of a single nut will not cause a major accident. The anti-loosening effect of the spring washer is achieved by the elastic force generated by the compressed spring washer and the edge of the gap of the spring washer being stuck on the connecting surface to achieve the anti-loosening effect. If the connection surface is important and scratches are not allowed, a flat washer should be added to prevent the spring washer from scratching the contact surface, but the anti-loosening effect will be reduced. In addition, when the through hole of the bolt has a large diameter, the contact area of u200bu200bthe spring washer is reduced, and a flat washer is added to increase the contact area. For example, a flat washer is generally added for a long hole. The function of gaskets-flat gaskets Flat gaskets are generally used in connecting parts, one of which is soft and the other is hard and brittle. Its main function is to increase the contact area, disperse the pressure, and prevent the soft texture from being crushed. The basic function of the spring of the spring washer is to give a force to the nut after tightening the nut to increase the friction between the nut and the bolt! The material is 65Mn (spring steel), the heat treatment hardness is HRC44～51HRC, and the surface is oxidized. The flat washer is a part between the connected piece and the nut. Generally, a flat metal ring is used to protect the surface of the connected part from being scratched by the nut and disperse the pressure of the nut on the connected part. Split washer spring washer (generally manufacturers will call washer 'washer') flat washer flat washer. 1. Grade C gaskets do not have Ra3.2 and deburring requirements. 2. Grade C is suitable for medium assembly series, Grade A is suitable for fine assembly series. 3. GB848-85 is mainly used for cylindrical head screws, and others are used for standard hexagonal bolts, screws and nuts. 4. Material mechanical property grade: steel 200HV; austenitic stainless steel A200. 5.
