Believe we all know that life without spring, tension spring factory today is for everybody to introduce tensile spring, tension spring belongs to a kind of helical spring, also can call it "spring torsion spring, tension spring, screw stretching and so on," each person's name is different, is less than we use in our everyday life of a spring, is a under axial tension spring, with the different compression spring is compressed spring is a spiral spring under axial pressure, then the tensile spring material is generally choose material is made and be become with circular cross section, The difference with the compression spring design is that there are two more "hooks" on both sides when not under the axial tension between the ring and the ring are in a closed state, the following stretch spring manufacturers will take you to understand what is the stretch spring and its application field.

What is a stretch spring

(1) "hook" is an important source of tension supporting the spring,

When it is not working, it is separated, while the stretching spring is opposite to the working principle of the compression spring. When the two ends of the stretching spring are fixed on the product, when the product is separated, it will have an effect and produce a strong tensile force, and will try to pull the product back together.

(2) the tensile spring hook shape is divided into many kinds, can be a pull hook, can also be a small hole and a variety of geometric shapes, this position can be according to the product to choose the shape of a "hook", among them with hooks for the classification of words can be divided into: side hook tension spring, tension spring, long hook hook tension spring, heart type hook tension spring, semicircle hook tension spring, the duck mouth hook tension spring and so on six kinds.

Two, the application field of stretch spring

(1) the tensile spring occupies an important position in the global market, from small medical equipment to the field of mechanical brake springs, tension springs application request you can specify all the TAB and pull hook, adjacent closely contact at the beginning of the tension spring coil, which helps to control load and stiffness, widely used in national defense, Marine, computer, electronic, automotive, mold, medical, biological, chemical, aerospace, railway, nuclear power, wind power, thermal power, engineering machinery, mining machinery, construction machinery, elevator, etc.
