What Should I Pay Attention To In The Process Of Automotive Standard O Rings Processing?

Doit Rubber Products Co.,Ltd | Updated: Oct 24, 2017

What should I pay attention to in the process of automotive Standard O Rings processing?
In order to protect the normal production of the Standard O Rings of the automobile, to improve the quality of the stamping parts, to reduce the cost and to extend the life of the die, we must correctly use and rationally maintain the Standard O Rings mold of the automobile and strictly carry out the "three inspection" During the inspection and inspection after use), and do the punch and maintenance work.
Automobile Standard O Rings in the mold processing process should pay attention to the following matters:
① mold parts must be processed during the process of grinding the standard parts of the O-ring parts of the burned car, should strictly control the Standard O Rings grinding process conditions and process methods (such as grinding wheel hardness, particle size, coolant, feed parameter);
② Automobile Standard O Rings processing should prevent the mold working parts surface to keep the knife marks. Mezzanine, cracks, impact scars and other macroscopic defects. The existence of these defects will cause stress concentration, become the root of the fracture, resulting in early failure of the mold;
③ automotive Standard O Rings grinding, grinding and polishing and other finishing and fine processing, access to a smaller surface roughness value, improve mold life.
In order to protect the normal production of the Standard O Rings of the automobile spring, to improve the quality of the stamping parts, to reduce the cost and extend the life of the die, we must correctly use and reasonably maintain the Standard O Rings mold of the automobile spring, strictly implement the "three inspection" , The use of inspection and inspection after use), and do a good job of punching and maintenance work.
Automotive spring Standard O Rings in the mold processing process should pay attention to the following:
① mold parts must be processed during the process of grinding burned car spring Standard O Rings parts surface phenomenon, should be strictly controlled automotive spring Standard O Rings grinding process conditions and process methods (such as wheel hardness, particle size, coolant, feed Quantity and other parameters);
② Automobile spring Standard O Rings processing should prevent the mold working parts surface to keep the knife marks. Mezzanine, cracks, impact scars and other macro defects. The existence of these defects will cause stress concentration, become the root of the fracture, resulting in early failure of the mold;
③ automotive spring Standard O Rings grinding, grinding and polishing and other finishing and fine processing, access to a smaller surface roughness value, improve mold life.
Spring Standard O Rings easy to install, low manufacturing costs, more widely used in the car. It is the use of Standard O Rings elastic deformation, so that the axial axial tension, while the Standard O Rings oblique tip also help prevent loose. However, this Standard O Rings in use due to heat or prolonged compression and loss of elasticity. Therefore, before installing the spring Standard O Rings, check whether the elasticity of its failure. Check the method is to see the Standard O Rings interface at both ends of the upper and lower staggered from a certain angle, if the stagger angle is small or not staggered, then the Standard O Rings has failed. At the same time, the Standard O Rings size should be matched with the corresponding bolt size, the Standard O Rings outer diameter slightly smaller nut diameter is appropriate.
Automotive spring Standard O Rings is a Standard O Rings in a, and the scope of application is very broad, suitable for many industries, is a use of elastic to work mechanical parts. Generally made of spring steel. Used to control the movement of the parts, to ease the impact or vibration, storage energy, measuring the size of the force, widely used in machines, meters.
Automotive spring Standard O Rings manufacturing materials should generally have a high elastic limit, fatigue limit, impact toughness and good heat treatment performance, commonly used carbon spring steel, alloy spring steel, stainless steel spring and copper Alloys, nickel alloys and rubbers. Automotive spring Standard O Rings manufacturing methods are cold-rolled and hot-rolled method.
