After molding, compression spring how qualitative effect is good?

After molding, compression spring how qualitative effect is good? Want to qualitative effect is good, the inside of the knowledge have a very big, then by the hui xian city ever explain for everybody compression spring molding after what matters needing attention. At the time that the manufacturing spring, when the spring after forming, generally must also after 220 to 330 degrees Celsius temperature to remove the solution of the in-situ stress hardening or hair blue, sometimes depending on the spring used in different working environment and compression spring, raw material characteristics of discretionary consider launching a hardened also has the solution of the quenching, therefore to increase the spring force of the spring. Conditioning treatment in the compression spring, the electromagnetic coil will become smaller, people should be applied at the moment to help shape tube. In your work at that time, pay attention to the spring and the mandrel card prison. In addition, people need to pay attention to some detail items, such as the compression spring on both sides of the water chestnut, also have burrs of electromagnetic coil inside and outside, it can create a pass and elegant appearance of the compression spring. At the time that the manufacturing is quite strict regulations, can not have a little slack! After forming, if appear bending condition, can
article select a circle in the spring when tight along the pivot, under the condition of vertical friction for several times, amplitude, friction to spring YingDeHua surface part. Spring is a kind of ductility are used to work in mechanical *. Made of ductile material * a deformation under the external force, after removal of external force is back to normal again. Also as a 'spring'. Usually made from spring steel. Spring types multifarious variety, according to the points, the key has a spiral spring, vortex coil spring, plate springs, special-shaped spring, etc. According to the bearing characteristics of spring wholesale spring can be divided into spring, compression spring, different line spring rashin bending and torsion spring and spring, according to the appearance can be divided into saucer spring, ring spring, plate springs, spiral springs, truncated cone vortex coil spring and torsion bar spring, etc. , by making the whole process to
is divided into cold coil spring and hot coil spring. General cylinder spring because of easy manufacture, and can be made according to the stress state of various forms, structure simple, so use * wide. Spring manufacture raw materials in general should have high ductility limits, ultimate strength, fracture toughness and excellent conditioning treatment characteristics, common carbon spring steel, aluminum alloy spring steel, stainless steel, spring steel and copper alloy, nickel base alloy and rubber, etc. Spring manufacturing methods have cold rolled and hot rolled. Spring wire with cold volume method is generally less than 8 mm in diameter, with more than 8 mm hot rolled method. Some spring after made to crush or blowing smoke pill solution, can improve the bearing capacity of the spring.
