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.
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 forming machine is usually refers to the production of various kinds of extension spring, torsion spring and all kinds of snap ring and other elastic element forming equipment.
This kind of machine the complexity of the higher than rolling compression spring spring coiling machine, also known as transfer machine tools.
saucer-shaped special-shaped spring small size, light weight, widely used in the buffer, vibration absorber, etc, and in stamping die, valve type clutch fasteners and widely application on petroleum and geological engineering machinery.
