In fact, a lot of goods on the market can use extension spring, tension spring manufacturer to introduce a total of three, respectively is: extension spring, torsion spring, tension spring, tension spring is under axial tension spiral spring, tension spring are generally made of material with circular cross section, in not received tension, tension spring circle and circle and tight without gap.

One, the difference that tension spring and other spring?

(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 source, tensile spring very different from the working principle of compression spring, compression spring pressure and counterproductive, and the extension spring is pulled open has a negative effect or stretch, when tensile spring open on both ends, spring will try to bring them back to together.

What field is the stretch spring generally used in?

(1) The application of the stretch spring includes the inside and outside of the motor vehicle, production and assembly, experiment, research and development, maintenance, etc. Tension spring market occupies an important position, widely used in national defense, ocean, computer, electronics, automobile, mold, medicine, biochemistry, aerospace, railway, nuclear power, wind power, thermal power, construction machinery, mining machinery, construction machinery, elevator and other fields.

Three, the production of spring spring closure type?

(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 according to the specific circumstances, when designing custom extension spring, the length of both ends of the adjustable spring hook in order to fully satisfy any stretch position load demand.

Four, what are the different stretch springs?

(1) is another common tensile spring hook spring, for the hook spring, 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 inherent braking functions, this ensures that the spring maximum tensile length can also continue to bearing static load, hook spring is often used to support the porch swing.

What parameters are required for 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.
