Q:Can springs be used for support?

If there is a condition, the upper and lower parts of the spring are mounted, similar to the bearing parts, and more thoroughly separated from the gears.

Q:What's the manganese content of spring steel?

The carbon content (mass fraction) of carbon spring steel is usually 0.62%~0.90%. In accordance with its manganese content is divided into general manganese content (mass fraction) (0.50%~0.80%), such as 65, 70, 85 and higher manganese content (mass fraction) (0.90~1.20%), such as 65Mn two categories.

Q:What is flat steel? Plain carbon flat steel? Spring flat steel

Flat steel, also called flat steel strip, is a long thin steel with a rectangular cross-section. According to the production process, it can be divided into hot rolled flat steel strip, fine shearing flat steel belt and cold drawn flat steel belt.Ordinary carbon flat steel - the component is ordinary carbon structural steel, suitable for wide range.Flat spring - flat steel used for making spring plates of automobiles, containing manganese.

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 kind of spring has the best performance?

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

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

but once you change the maintenance fees are higher than the artificial spring spring price itself

Q:What are the main functions of spring?

The storage and release of energy, for example, the clock spring bolt spring

Q:Buffer spring buffer for automobile

With abrasion resistance, cold resistance, impact resistance, aging resistance, water resistance, service life of 2 - 3 years. First, use Jack to support the body and clean the spring with water. After the installation is complete, the automobile damping buffer rotating around a few times, check whether the spring into full spring slot; the outer edge is rub the fender buffer; buffer overlap or not. Also, in order to avoid the shock absorber, when the vehicle is moving down to the bottom of the spring, it is necessary to install a stop card.

Q:Cold rolled coil spring spring and difference "

The main production process is different, the compression spring as an example:The typical process of coil spring: blanking - end processing (rolled or forged flat) - heating - - - quenching - tempering spring roll grinding end - compressor (load - Test), shot peening (cleaning) - coating.Cold roll spring does not require heat treatment of material roll, point line process: rolling, annealing, stress to both ends of the surface grinding, (blast), (the whole school), (BKS), standing or forcing treatment, surface inspection and treatment.Coil spring is mainly used for rolling large spring, heating easily after twisting forming, springback is smaller, molding after quenching and tempering treatment.The cold coiling spring is directly coiled with spring steel wire, and the resilience is greater, and the winding tools need to consider the springback compensation amount and roll into the direct tempering process.
