Does The Compression Spring Need To Be Annealed After It Is Calibrated?
- Jun 26, 2018 -

Compression spring is the most common type of spring. For our technology, it is also necessary to pay attention to the details of the type of spring. Before and after tempering, before and after the correction, before and after grinding the dimensions, it is necessary to pay attention to the attention of the adviser. Today, Let's talk about whether the annealing needs to be corrected after the compression spring is calibrated.

Whether the stress spring annealing is required after the compression spring is calibrated. Compression spring correction is through a certain tool, so that the compression spring produces local plastic deformation to meet the requirements specified on the pattern. The compression spring correction on the one hand increases the dimensional accuracy, on the other hand it often has an adverse effect on the performance of the spring and even causes damage. In order to reduce the effect of the correction on the performance of the compression spring, a stress relief annealing treatment should be performed after the correction. After the heat treatment, the effective coil shall be subjected to stress relief annealing; the compression spring repaired by using the plane or hot pressure of the grinding support ring (the temperature is at least lower than the actual tempering temperature of 20°C) may not be subjected to stress relief annealing. Spring characteristic measurement.

Compression springs are the most commonly used springs. After compression springs have been used for a period of time, the compression springs will produce partial errors due to deformation. What should be done at this time? Do not worry, the following Xiaobian will teach you how to correct the pressure spring:

In fact, for the helical compression spring, after the grinding of the end surface is completed, if the free height, the verticality, the pitch, the outer diameter, and the like of the spring do not reach the specified deviation values, correction processing is often required.

Corrected operations are now usually mostly manual or semi-manual jobs. Commonly used tools are: If the wire is more than four millimeters in the compression spring, we usually use more hand to press the press, pitcher, punch and other tools; if the wire is under four millimeters of the compression spring, then we often have a wedge-shaped edge Special tools for the mouth, pliers, hammers and other tools. Corrective machining is the use of these tools to locally produce plastic deformation of the compression spring to achieve the required dimensions of the pattern.
