Common questions about stretch springs, how much do you know about the small series and you learn together, common questions about stretch springs are divided into 4 categories.

1. What is the type of spring closure?

(1) threaded embedded nettley, cross center TAB, retractor, more holes, shrink pores, rectangular convergent and teardrop-shaped convergent, nettley, is apart from the length of the spring can be based on specific circumstances, when designing custom extension spring, can adjust the length of the spring hook on both sides in order to fully satisfy any stretch position load regulation.

2. What are the different stretching springs?

(1) the other is the common extension spring hook spring, spring for hook, in ChangGang ring, through the spring center, and at the other end was hung in the end of loading, hook spring is very suitable for potential overworked, and the spring has inner brake function, which can ensure that spring reaches maximum tensile length can also continue to bearing static load, hook spring is often used to support the porch swing.

3. What parameters must be used in the design of the stretch spring?

(1) Dimensions: outside diameter, inside diameter, spring wire diameter, stretch length and free length

(2) Tensile length refers to the length of the spring under the maximum tensile state

(3) The free length refers to the total length of the spring under no load

(4) Spring stiffness and maximum load

(5) The spring stiffness refers to the load change per unit of deformation.

(6) The maximum load refers to the load carried by the spring under the maximum tensile state.

4, the difference between the tension spring and other springs?

(1) the tensile spring and other spring with is not his ends is made of the hook, extension spring hook is used to ensure the tension of the spring, tension spring and compression spring, is very different to the working principle of compression spring pressure and counterproductive, and stretching the spring is pulled or stretching of the reverse effect, when tensile spring open on both ends, spring will be trying to pull them back together.
