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.
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.
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.
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.
