Stainless steel non-standard China Nut is the basic principle of fastening. Stainless steel non-standard China Nut is a universal tightening stainless steel non-standard China Nut. Fastening method Non-standard stainless steel parts are nuts, which are screwed together by anchor bolts or extruder screws to achieve the fastening effect. They are all the original China Nuts that must be used to manufacture machinery and equipment. The non-standard stainless steel China Nut is a China Nut that is closely connected to industrial equipment. According to the internal and external threads, the stainless steel non-standard China Nut and the screw can be connected together. At the same time, the following content actually provides you with four methods to avoid the non-standard stainless steel China Nut from slipping. The tightening of mechanical equipment should immediately limit the relative overturning of the lock nut to the stop part of the lock nut. For example, it is difficult to pick up the pin, connect the stainless steel wire and stop the seal. Since the stop part of the lock nut has no pre-tightening force, the lock part of the lock nut can only work when the nut is loosened and returns to the stop part. Therefore, in practice, there is no method of tightening the lock nut, just to avoid withering.
After tightening, riveting, punching, welding, bonding and other methods, the lock nut pair loses the kinematic characteristics of the pair, and the connection cannot be removed. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble and assemble. Therefore, it is necessary to destroy the lateral disassembly type of the anchor bolt. Friction fastening is a widely used fastening method. The positive pressure generated by this method does not change with the external force of the lock nut to the center, thereby generating sliding friction force, which prevents the relative overturning of the lock nut pair. This positive pressure can be obtained by clamping the lock nut pair in the radial direction or in the other two directions. Such as the use of ductile sealing rings, double nuts, lock nuts and plug-in lock nuts.
The structural fastening of non-standard stainless steel parts is the repeated main structure of the lock nut, that is, the fixing method of the Down lock nut. The three advantages of stainless steel non-standard parts are as follows:
Excellent seismic effect: when tightening the external thread, the thread on the top of the anchor bolt firmly enters the 30° wedge-shaped slope of the nut and is clamped, and releases the reverse interaction force on the wedge-shaped slope to become 60 ° angle instead of 30 ° angle. Stainless steel bolt is a kind of stainless steel China Nut that we often see in daily life. Key points are used in environmental protection machinery, medical equipment, communication equipment, power distribution equipment, electronic equipment, appearance equipment, food machinery equipment, petrochemical equipment, marine equipment, valve fittings, pipes, metal curtain walls, outdoor venues, sports facilities, outdoor decoration design Wait
Stainless steel non-standard China Nut finishing operation method:
1. Arrange 303, 304, 316 stainless steel bolts, put the liquid medicine into the grinding equipment, and grind together with the stainless steel bolts and screws. It takes 3-30 minutes to complete and clean (depending on the oil level).
2. Bolt Factory arranges 667, 201, 202, 418 stainless steel bolts and screws; put the solution into the grinding equipment and grind together with the screws. After the stainless steel non-standard China Nut turns black, it will be ground for 5-10 minutes. Others will sign up for a small amount of this detergent to make the screws white (take 0.5-1 kg of this detergent and sign up for 3-5 times the water, and put them in the grinding equipment after the screws are rotated. White ) Grind and clean with cold water. Then you can proceed to the next process-→ grinding and polishing.
