Q: Is spring steel manganese steel?: Spring steel is not manganese steel, there are many kinds of spring steel, manganese 65 is more commonly used spring steel, as well as carbon spring steel and alloy spring steel.Manganese steel refers to the high manganese content of carbon steel structural steel.

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: Hydraulic diagram of the one-way valve has two kinds of drawing, with a spring, without a spring, what is the difference between automatic reset function is not? Without a spring, it will not be repeated: Most of the one-way valves are springs, but the springs are usually soft and the flow resistance can be neglected. Normally, a one-way valve with a pressure of more than 0.3 MPa draws a spring mark on the hydraulic schematic.

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 flat steel? Plain carbon flat steel? Spring flat steel: It is the name of a steel produced according to a certain specification, such as angle steel, channel steel, etc. ordinary carbon flat steel and spring flat steel are different materials used to make flat steel

Q: What is an independent bagged spring?: Independent bags, spring inner bladder, column spring, non-woven fabric wrapped, unique ultra quiet design, for you and your sleeping partner to create a warm sleep atmosphere.Independent bagged spring bladder, designed and manufactured by leading domestic production line, fully conforms to the Qi curve formed when maintaining human body sleep. Straight cylindrical spring, non-woven separated, effectively avoid the metal liner due to friction also belongs to the voice with humanization ultra quiet design, to create a warm atmosphere for you to sleep, and when you sleep with the move will not give you his lying position caused by any vibration, so as to ensure the quality of your sleep. Straight cylinder liner using the circular shaped spring, with extraordinary comfort and elastic stability.

Q: How should we choose the spring material?: Large and medium-sized spring for load precision and stress higher, should choose cold drawn or cold drawn after polishing steel, for load precision and stress lower spring products, can choose hot rolled steel.

Q: The shop glass spring door is too tight, how to adjust?: The spring of the stainless steel cover apart, there are 3 word brass wire, a label is in the middle of the elastic adjustment, Zuo Song left right tight, elastic, elastic, dextral (clockwise) that don't mix too much, a little bit, take it for a test drive, if you do not have the best mark pen in a gong wire above the mark, next to the two speed is adjustable,Note, the label ripped open, there will be no warranty, and all gongs silk must not be twisted out, only minor adjustments

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.

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).
