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:The glass door spring is broken. How much would it cost to change it?
The price of the spring itself is about 200-800, plus part of the labor cost. After all, it's very expensive. There are about 150 of the spring, but the quality is not good, or safety first. Labor costs are probably about 120. Specific prices should be based on your actual situation, you and the master speak.
Q:How should we choose the spring material?
In determining the material section, shape and size, should be preferred in the national standard and standard series size, try to avoid using non standard materials.
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:What kind of production equipment does spring factory usually have?
Multi function forming machine, coil spring machine, 580 press spring machine, extension spring machine, etc.Small heat treatment is also needed
Q:Stainless steel and spring steel hardness, who is hard?
Hardness is checked by indentation, not by pliers.Stainless steel, of course
Q:How to choose spring steel material?
In choosing materials, the material shall be considered in combination with the diameter or thickness of the material. The size of commonly used spring steel in oil is shown in table 3-10.7mm below diameter carbon spring steel used for oil quenching, the size of all kinds of spring is slightly larger, available manganese spring steel quenching. Well, such as 65Mn spring steel 15mm diameter can be through quenching in oil, available water quenching diameter of 25mm. For the spiral spring, leaf spring and disc spring middle section can be used manganese spring steel, 60Si2Mn steel can be used as oil quenching diameter of 25mm, for the spring to withstand heavy loads with large cross section, can choose the hardenability of high chromium silicon steel, chrome vanadium steel wire, such as 60Si2CrA.50CrVA, 45mm in diameter can also through quenching in oil.
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:Can springs be used for support?
The following individual ideas do not represent the bestFriction is bound to damage,Gaskets can be used to prevent direct friction between the spring and gear to lubricate, optimize wear and prolong life.
Q:What's the manganese content of spring steel?
Carbon spring steelThe carbon content (mass fraction) of carbon spring steel is usually 0.62%~0.90%. In accordance with its manganese content is divided into general manganese content (mass fraction) (0.50%~0.80%), such as 65, 70, 85 and higher manganese content (mass fraction) (0.90~1.20%), such as 65Mn two categories.
