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: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 are the categories of springs?

Linear springs, linear springs from top to bottom of the thickness and density unchanged, the elasticity coefficient for fixed values. The dynamic response of spring of this design can make the vehicle obtain more stable and linear, is conducive to better control the vehicle driver, for vehicle performance orientation and competitive disadvantages of vehicles is of course affect comfort.

Q:What kind of spring has the best performance?

Number of coils, coil number is greater than the difference between the 0.25 circle, will directly affect the intensity of emotion.

Q: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"

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

Spring: Spring quenching hardening is the steel is heated to the critical temperature of Ac, or Ac: the above heat preservation time, the austenite with greater than the critical cooling rate of rapid cooling, so as to obtain the heat treatment method of martensite.

Q:How to process Spring Steel

After the spring is made, shot peening can produce residual compressive stress on the surface of the spring so as to offset part of the working stress on the surface layer and restrain the formation of surface cracks, which can significantly improve the fatigue limit of the spring.

Q:How to choose spring steel material?

Spring steel is selected on the basis of the section size of the spring, such as high carbon steel 65, suitable for production in the spring of 12 ~ 15mm under section 60CrMnA, suitable for the production of spring and the car less than 50mm in diameter with heavy-duty spring. The 30W4Cr2VA is used to make heat-resistant spring for work below 500 degrees centigrade. Generally, hot forming springs are generally quenched and tempered at moderate temperature to obtain a structure with a maximum elastic limit and fatigue properties

Q:The shop glass spring door is too tight, how to adjust?

Check the glass door first, is it upside down or is it shifted underneath?.After fixing, open the spring panel, and see the adjusting bolt, then adjust the position slowly.Or the upper side of the door folder to be adjusted.Adjust or adjust to stabilize, avoid glass deformation, damage.

Q:What's the spring material to?

1, with alloy spring steel, respectively, there are several kinds of steel: 55Si2Mn or 50CrVA and 30W4Cr2VA, these alloy spring steel;2, manufacturing process:Coil the machine first into the spring and then proceed with the proper heat treatment process to get the spring you need.
