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.
in the convex screw compression special-shaped spring due to the small spring ring on both ends can be embedded into the circle in the middle, and so the larger deformation can be obtained.
For example, some of the convex type auto brake spring, and has been in a tight state at ordinary times, open the car valve, spring back deformation, drives the brake of automobile brake.
Haircut convex pusher is also used in helical spring this characteristic, the effective space to obtain larger deformation and stress.
make a special-shaped spring:
generally is spiral line, and then the breakpoint tangent to draw a circle, build a plane scanning with respect to ok, if you want to spiral is change, below have draft Angle and outline.
Draft Angle is the Angle of input, contour is to draw a curve for your reference, in the sketch drawing can be, and rule curve, is the change of pitch,
the difference between the special-shaped spring and conventional spring is spring itself is irregular, the bending Angle and a large number of complex design.
Suitable for some special occasions.
