Q:What is an independent bagged spring?
Independent bagged spring is a spring with non-woven package, barrel type design can prevent the spring friction and swinging or noise, no influence between spring, elastic energy in accordance with the size of individual expansion, different weight average and proper support of various parts of the body to keep the spine straight, make sleep more comfortable. Bagged spring than ordinary spring production process is more complicated, the cost is higher, so the price is slightly expensive. But human health is obviously.
Q:Displacement problems in a spring oscillator
In short, in vibration and wave, it is not easy to make mistakes when we grasp the difference and relationship between "displacement" and "displacement relative to the balance position"
Q:How to choose spring steel material?
The cold plastic deformation of the cold drawn spring material is high, and most finished steel wires have reached the required mechanical properties when the steel mill is out of the factory. The surface quality of the steel wire is high, and the spring manufacturing process 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. This kind of steel wire should be used preferentially for the tension spring with small bending radius and the compression spring with smaller diameter of steel wire. Oil tempered steel wire for residual stress, cold forming, precision spring is easy to control, low temperature tempering after the size change is very small, especially because there is no residual stress relaxation resistance than carbon spring steel wire lead quenching and cold drawing good. For the spring with higher size precision and the thicker diameter of spring steel and the good spring resistance, the oil quenching and tempering steel wire shall be used.
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:What's the spring material to?
65Mn, 55Si2Mn, 60Si2Mn, 50CrVA, 75, 85, 55CrMnA, 60Si2CrVA, 60Si2MnA, 70, 65, 50CrMo, 55SiMnMoVNb, 60SiMnMoA, 65Si2MnWA, 70Si3MnA, and so on
Q:Is spring steel manganese steel?
The most important characteristic of manganese steel is that it can be worked hard under strong impact and extrusion, and its wear resistance is improved, mainly by its working hardening.Spring steel mainly requires large elasticity, high yield strength, and can withstand repeated load without breaking. Spring steel only after heat treatment (quenching + medium temperature tempering) can show its high elasticity, that is, after a certain load, does not occur permanent deformation. The content of Mn in spring steel is much lower than that of Mn in manganese steel.
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
General one-way valve is spring to reset, as for drawing may be the standard of drawing is not the same. As long as no oil passes, it closes.
Q:How to distinguish between spring steel and stainless steel
Stainless acid resistant steel, or stainless steel, is made up of two parts: stainless steel and acid resistant steel. In short, steel that resists atmospheric corrosion is called stainless steel, and steel resistant to chemical corrosion is called acid resistant steel. Spring steel is a quality carbon steel, but it can rust.
Q:What kind of spring has the best performance?
Spring verticality, verticality is bad, will directly affect the strength and life.
Q:Buffer spring buffer for automobile
The automobile spring buffer (cushion glue) is a kind of rubber product with high elasticity and high tenacity. It belongs to the automobile refitting parts. The utility model is used for installing the spiral spring of an automobile suspension system, and mainly acts as a buffer shock absorber and protects the shock absorber. This function is a physical function.The buffer is made of an open circular ring with a groove (for holding a coil spring), with two, three or more holes on each side. According to the standard specification of the spring spacing, the buffer rubber is divided into seven standard models: A+A, A, B, C, D, E and F. In theory, these seven models can cover the world's largest part of the spiral spring shock absorbers required.
