Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

Small manual for all kinds of cylindrical spring spring tension and compression testing machine, disc spring, spring, spring, leaf spring, special-shaped spring precision spring tension, stress, displacement, stiffness and precision test and analysis.

JB/T 7796-1995, JB/T 7796-2005 "spring tension test machine test method"

JIS B7738-2001 "compression and tensile disc spring test machine"

1, to determine whether the spring is qualified by measuring the corresponding force value F by measuring the deformation of the spring H or H.

2, through the spring force value F, to measure the corresponding spring deformation H or height H to determine whether the spring is qualified.

3, one or more tests can be carried out to determine whether the spring is qualified.

4, it can be measured piecewise, and can calculate the stiffness (elastic coefficient) K and average stiffness of each segment.

5, sampling inspection for products, batch testing can also be carried out (mechanical parts have batch test device).
