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 about the size of the elasticity?
The force is analyzed and the force is decomposed along the positive plane and its vertical direction
Q:What is an independent bagged spring?
Independent spring: there are different springs, respectively, according to different weight, set up independent spring in different locations. Of the two men lying on it, one rolled over or left, and the other was not affected at all. Two mattresses in the middle area, the spring has different support strength, so won't feel sleep in the two bed crevice.
Q:How to process Spring Steel
The available oxygen converter furnace and open hearth furnace or general production of spring steel; high quality spring steel or better quality with special properties, furnace or vacuum refining furnace. The content of carbon, manganese, silicon and other major elements in spring steel is narrow, and the chemical composition must be strictly controlled during smelting. When the silicon content is high, it is easy to form bubbles and other defects. After the ingot is rolled and rolled, the cooling is not easy. Therefore, the raw materials used for smelting must be dry, as much as possible to remove gas and inclusions, and to avoid overheating of the steel.
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: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:Cold rolled coil spring spring and difference "
Coil is to burn the red, generally large diameter to coil
Q:What are the main functions of spring?
Control the movement of a machine, such as a spring that controls the opening and closing of a cylinder valve in an internal-combustion engine, and a control spring in the clutch
Q:What is spring pressure and height?
That is, the spring is compressed to the height of the full circle.
Q:How to distinguish between spring steel and stainless steel
With saline in two days to put a steel can see rust is a way (can, for 304 stainless steel 201 stainless steel will rust, only less); another way is to put the two kinds of steel can see the reaction is on spring steel in dilute sulfuric acid, oxalic acid, not the reaction or reaction of small stainless steel.
