The slight difference from regular springs is that the spring itself is irregular, with bending and a large number of complex angle designs. And the manufacturing and processing techniques also have relatively high requirements, as well as equipment requirements. Usually it is a computer machine winding. Due to the large number of winding angles and bends, the production speed is slow. Due to its complexity, the production and processing of irregular springs often represent a company’s technical level. Common uses of irregular springs include washing machines, elevators, sock clamps, handicrafts, lighting fixtures, and medical equipment.

Method for making irregular springs:

1.Spiral line, then create a plane and draw a circle in the direction of the breakpoint tangent, and sweep it. If you want the spiral line to be variable, there is a draft angle and contour below. The draft angle is the input angle, and the contour can be drawn by drawing another curve as a reference in the sketch. There is also the rule curve, which is the variation of pitch.

2.A method for forming a linear spring, comprising the following steps: on an extension of the centerline of a spindle, three or more radially arranged forming tools are pushed forward in a direction perpendicular or substantially perpendicular to the centerline of the spindle, around the centerline of the spindle guided by the wire, and the forming tools collide with the wire fed in from the top portion of the spindle. The method further comprises the following steps: rotating a rotating table on which the forming tool is mounted around the centerline of the spindle, so that the wire contact surface of at least one required forming tool is in a direction suitable for forming the wire; And after the rotation of the rotating table mentioned above, the required forming tool is pushed towards the extension direction of the centerline through a cooperative driving device among many driving devices. The number of driving devices mentioned above is greater than the number of forming tools mentioned above, and they are arranged radially around the centerline of the spindle outside the rotating table used for forming linear springs.
