The concept of special-shaped
spring:
with conventional spring slightly difference is spring skill is irregular, bending Angle and a large number of complex design.
And manufacturing craft is also relatively have a requirement, equipment is also more requirements.
Usually computer machine winding.
Because of the winding Angle, bending, so the production speed is slow.
Because of its complexity, shaped spring production and processing, often can represent a company's technology level.
。
1.
3 shaped spring common use: washing machines, elevator, socks clip, handicrafts, lighting, medical apparatus and instruments on
a linear spring forming method, it has the following steps:
in a main shaft centerline on the extension of wire on the orientation of the center of the spindle in the perpendicular to the or basically perpendicular to the direction of the spindle center line, will be three or more radial arrangement of the forming tool to move forward, and make the forming tool collision part brought in from the top of the main shaft of wire rod, its characteristic is that the method also includes the following steps: make a installed on forming tool around the spindle center line of the rotation of the turntable, forming tools needed to make at least a wire contact surface is suitable for the wire forming direction;
And after the above the turntable rotation, through the work of a lot of driving gear drive, the forming tools needed to advance towards an extension of the center line, the number of the drive, more than the number of the forming tool, and used in forming a linear spring around the outside of the main shaft of the centerline of the turntable radial layout.
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.
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.
