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 is an independent bagged spring?
The characteristics of independent bagged springs is independent bagged spring each spring can be independent of support, stretching alone, completely conform to the body curve, so that all parts of the body are the best care, with ergonomic, closely supporting effect. Spring tube respectively operation, a force, not elsewhere, even if the pillow was over, it will not affect the sleeping of another, especially by adding a layer of high elastic cotton blanket and wave type sponge bed, bump by using body wave sponge flip natural movement to achieve the massage and health care enjoy the ultimate role of sleep.
Q:How to process Spring Steel
Spring steel has excellent comprehensive performance, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization, precise shape and size).
Q:The glass door spring is broken. How much would it cost to change it?
Replace the ground spring, the price of the earth spring itself, but also part of the labor costs, after all, it is very expensive. Land springs in general, if used in general, that is, about 150, but with labor costs, usually around 80. Specific prices should be based on your actual situation, you and the master speak.
Q:What kind of spring has the best performance?
The length of the spring, with a number of differences between the spring, will affect the product intensity consistency.
Q:Cold rolled coil spring spring and difference "
Difference: the main annealing time is different. In the production process, is the first volume of coil spring and annealing, and spring is the first cold roll annealing, and then roll. Similar to cold rolling and hot rolling of steel.Note: spring making methodProduction method of cold rolled coil spring: to stress annealing, end surface grinding, (blast), (the whole school), (BKS), standing or forcing treatment, surface inspection and treatment.Production method of coil spring: blanking, end processing (rolled or forged flat), heating, coiling, quenching, tempering, grinding end to compression to (load test), shot peening (cleaning), coating.
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: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:What is spring pressure and height?
Press the compression spring to the point where each circle is tightPress height = = (total coil number -0.5) * steel wire diameter
Q:How to distinguish between spring steel and stainless steel
Mainly depends on the performance of spring steel, good elasticity, stainless steel toughness. The color should be slightly white stainless steel. Spring steel is easy to rust, with a little salt a day you can see the stainless steel does not rust.
