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 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.
the difference between the special-shaped spring and conventional spring is spring itself is irregular, the bending Angle and a large number of complex design.
Suitable for some special occasions.
make a special-shaped spring:
generally is spiral line, and then the breakpoint tangent to draw a circle, build a plane scanning with respect to ok, if you want to spiral is change, below have draft Angle and outline.
Draft Angle is the Angle of input, contour is to draw a curve for your reference, in the sketch drawing can be, and rule curve, is the change of pitch,
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.
