In 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.
because of spring varieties and of the great variety of shapes, ask spring mechanical energy to meet the requirements of the adjustment convenient, applicable to many varieties.
New special-shaped spring forming machine can finish from wire into to the coil spring, bending and a series of complicated movements, also can finish at the end of the spring hook, ring after processing.
It not only can rolling compression spring, and the extension spring,
torsion spring, double head type torsional spring, double spring, all kinds of spring that can be easily made.
Foreign special-shaped spring forming machine type is more, the main models have west WAFIOS ZO, FTU, France TC, HP company type of MS, the AT, Japanese aoye, MCF, Japan's emerging, VF -
The type 800, etc.
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.
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.
