Q:What is spring pressure and height?

That is, the spring is compressed to the height of the full circle.

Q:What's the manganese content of spring steel?

Refer to Baidu Encyclopedia: 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.

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:What kind of spring has the best performance?

Spring surface scars, spring surface injury to use a magnifying glass to see, manufacturers generally use 300 times electronic magnifying glass, spring 300 times, see the injury, the impact on life is very big.

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.

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: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:What are the main functions of spring?

Absorb vibration and impact energy, such as damping springs in various kinds of vehicles and springs of various buffers

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: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.
