Volute special-shaped spring spiral similar to the role of the conical spiral special-shaped spring, it absorb the energy of the big, under pressure 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.
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.
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 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.
