Although the spring is a small part in the entire manufacturing industry, its role is by no means small. Whether it is machinery manufacturing, industrial manufacturing, etc., springs are inseparable. As one of the basic parts, in order to make springs have better quality, Shenzhen spring manufacturers will generally implement it through correction methods.
The spring is a basic part that uses elasticity to work. It is generally made of steel materials. Space is used to control the movement, buffer, vibration of machinery, can store energy or measure the magnitude of force. Widely used in machinery, instruments, etc. The application area involves almost all areas of the national economy. The correction of the spring is also one of the commonly used processes in the spring production process. The correction work is mainly divided into these three steps.
1. Outer diameter. Generally, the outer diameter of the coil spring can be guaranteed to be deviated, but the winding ratio of the spring is too large and the outer diameter tolerance of the spring is very strict, so the outer diameter needs to be corrected.
2. Pitch and height. Pitch is the main criterion for acceptance. If the free height of the spring cannot be guaranteed, a correction method can be used to adjust it.
3. Verticality. In order for the spring to meet the requirements of high-accuracy verticality, the verticality and accuracy can be improved through correction under the premise that it cannot be guaranteed during wear.
