Spring Says How To Deal With The Problems That Springs Often Appear
- Jun 26, 2018 -

The spring load fails to meet the drawing requirements. When the spring load fails to meet the drawing requirements, it can be analyzed from four aspects: wire diameter, spring free height, spring diameter, and number of working cycles. The effect of spring manufacturing tolerances on the spring load: spring material causes spring stiffness error and the relationship between the two is proportional to 4 times; the spring diameter causes spring stiffness error, which is a 3 times inverse proportional relationship; the greater the number of working turns, the smaller the stiffness.

Deformation of the spring and failure to reach the drawing requires that the spring be handled lightly and gently. Otherwise, the outer diameter may become large and the spring may be distorted and deformed. When winding a spring with a large convolution ratio and a large pitch, the spring workers Special attention should be paid to the operation of the process, such as slow speed when reversing the vehicle, lightness when transporting a coiled spring blank, and minimal movement before stress relief annealing. The springs must be arranged neatly in the furnace. The springs with special shapes or easily deformed should be equipped with corresponding auxiliary tools. When the springs are grinding the end surfaces, they should be carefully ground. Otherwise, the verticality of the springs will be affected.
