Disc 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.
in the limited space, often with rectangular section materials of the spring, because spring made of rectangular section materials can be in the same space and obtain larger load under the same deformation.
This kind of spring compared with the material of the spring with circular cross section, in the same space, its cross-sectional area is large, so it absorbs energy is also big, it can be used in heavy machinery, stamping die or special big spring stiffness.
domestic winding tail hook torsional spring common plane is a straight spring coiling machine.
It adopt gear rack mechanism, feeding way is given to institutions, reciprocating one-way form a core winding coil spring, the pitch control depends on the vertical direction of the pole by CAM.
Cut off the agency is also controlled by the CAM, this kind of machine can only make simple torsional spring, homebred model is Z56 -
25.
Can only produce wire diameter in 2.
5 mm below the torsional spring.
to make snap ring use the machine according to bending machine, in the form of transfer, wire through feeding into the mold, then through a series of fixtures will bend the wire into the required shape.
This kind of machine tool is the key to the mould design and manufacturing, must Ba when changing varieties should be replaced mould and tool, etc.
Adjust the required for a long time.
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.
