Q:How should we choose the spring material?

Whether the spring is good or not is of great importance to the choice of the spring material. In general, selection of spring material, should take into account the load properties, spring force, various factors should be size, working conditions and price, etc.. Specific can follow the following principles: 1) in determining the shape and size of spring material, should be preferred dimensions behind national standards or standard stipulated, try to avoid using non standard materials. Although the spiral spring square or rectangular cross section material, the elastic deformation can be higher than, can make the small volume of the spring, for spring, in small space or under impact load but because of square or rectangular section material shortage, the price is higher, and the spring forming is difficult, so should be avoided. Ring section spring material diameter series see table 3-9. 2) the degree of cold plastic deformation of cold drawn spring materials is high. Most finished steel wires have reached the required mechanical properties when they leave the factory. The surface quality of the steel wire is high, and the manufacturing process of the spring is simple. For springs of medium or small spring or high fatigue life, the cold spring or cold drawn spring or steel wire or strip shall be selected as far as possible. Carbon spring steel wire (group I, group II, group II A, dish group) and important uses of 65Mn spring steel wire during the cold drawing process caused in large residual stress, the larger the size change after low temperature tempering, and thus affect the dimensional accuracy of the spring. For the bending radius of smaller tension and torsion spring, as well as smaller steel wire compression...

Q:What are the categories of springs?

The coil spring, the torsion spring, is a spring that bears torsional deformation, and its working part is tightly wound into a spiral shape. The torsion spring end is made of twisted arms of various shapes rather than rings.

Q:What kind of spring has the best performance?

Spring verticality, verticality is bad, will directly affect the strength and life.

Q:What kind of production equipment does spring factory usually have?

Multi function forming machine, coil spring machine, 580 press spring machine, extension spring machine, etc.

Q:I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching

First of all, you don't know whether the material is suitable for springs.Gas torch burning red spring, water or oil? The quenching temperature is not too good. It's too difficult to control: it can't be just right. Besides, tempering is necessary after quenching. Without tempering, of course, very brittle (hardened case), to the temperature above 400 degrees insulation for a period of time.If you're patient, experiment slowly, I hope. But if you're discouraged, it's hard to succeed.

Q:The glass door spring is generally guaranteed for several years

Quality and price are pretty much the same. Many other miscellaneous brands of spring can be guaranteed for five years, three years it is best to begin with a reliable brand

Q:What are the main functions of spring?

Absorb vibration and impact energy, such as damping springs in various kinds of vehicles and springs of various buffers

Q:Is spring steel manganese steel?

With wings are not necessarily the "angel", also may be "bird". Steel not containing Mn elements is called manganese steel. Manganese steel refers to those with high strength steel, mainly used for impact, friction and extrusion, mainly wear and tear.

Q:Buffer spring buffer for automobile

Next, put a soapy water or lubricant on the loose coil spring. Then, insert a strong buffer of soap, water or lubricant into the loose spiral spring gap, and then release the car body after confirming it.Finally, the distance between the damping springs is a matter of concern for mounting the shock absorber. The distance between the springs is equal to the length of the shock absorber. If it is more difficult to squeeze by hand, loosen the screw of the shock absorber, and let the damping spring relax 2 - 3 centimeters.

Q:Cold rolled coil spring spring and difference "

Coil is to burn the red, generally large diameter to coil
