Special-shaped
spring with conventional spring difference is spring itself is irregular, the bending Angle and a large number of complex design.
Suitable for some special occasions.
volute special-shaped spring spiral similar to the role of the conical spiral special-shaped spring, it absorbed energy under pressure is big, because of manufacturing difficulties, only for the special case of limited space.
Plane volute spring coil number is more, the deformation is larger, can store larger energy, much used in the compression spring and instrumentation in energy storage element.
special-shaped spring through what to get metal protective layer:
metal cover a lot of more phyletic, in terms of special-shaped spring, usually use the method of plating for metal protective layer.
Plating layer can not only protect from corrosion, and at the same time can improve the appearance of the special-shaped springs.
Some electroplating metal also can improve the working performance of special-shaped spring, such as to improve the surface hardness, increased wear resistance, improve the thermal stability, prevent rays, corrosion, etc.
But if it's purely for the sake of special-shaped spring corrosion, generally choose the electricity galvanized layer with cadmium plating layer.
Zinc nickel plating special-shaped spring is stable in dry air, almost no change, is not easy to change color.
In humid air will generate a layer or carbon zinc carbonate white film.
This layer of dense membrane can prevent corrosion continue to suffer.
So the galvanized layer for special-shaped spring under the condition of atmospheric corrosion protection layer.
All contact with sulfuric acid, hydrochloric acid, caustic soda solution phase, and in the moist air in the atmosphere in the sulphur trioxide of special-shaped spring, unfavorable use zinc plating.
because of spring varieties and of the great variety of shapes, ask spring mechanical energy to meet the requirements of the adjustment convenient, applicable to many varieties.
New special-shaped spring forming machine can finish from wire into to the coil spring, bending and a series of complicated movements, also can finish at the end of the spring hook, ring after processing.
It not only can rolling compression spring, and the extension spring,
torsion spring, double head type torsional spring, double spring, all kinds of spring that can be easily made.
Foreign special-shaped spring forming machine type is more, the main models have west WAFIOS ZO, FTU, France TC, HP company type of MS, the AT, Japanese aoye, MCF, Japan's emerging, VF -
The type 800, etc.
Nowadays, the adoption of News in leaf spring hardware industry is quite common.
