What is a special-shaped spring?

A slight difference from conventional springs is that the springs are irregular, with bending and a large number of complicated angle designs. The manufacturing and processing techniques are relatively more demanding, and the equipment is also more demanding. Generally, it is wound by a computer. Because of the winding angle There are many and many bendings, so the production speed is slow. Because of its complexity, the production and processing of special-shaped springs can often represent the technical level of a company. 1.3 Common uses of special-shaped springs: washing machines, elevators, sock clips, handicrafts, lighting, medical treatment On the device

　　A method for forming a linear spring, which has the following steps: on the extension of the center line of a main shaft, around the center line of the main shaft guided by the wire, in a direction perpendicular or substantially perpendicular to the center line of the main shaft , Pushing three or more radially arranged forming tools forward, and making the above forming tools hit the wire material fed in from the top part of the main shaft, characterized in that the method further includes the following steps: one is installed on it The rotating table of the forming tool rotates around the center line of the spindle, so that the wire contact surface of at least one required forming tool is in a direction suitable for the wire forming; and after the rotating table is rotated, it passes through many driving devices A cooperating driving device for forming the required forming tools to the extending direction of the centerline. The number of the above-mentioned driving devices is more than the number of the above-mentioned forming tools. It is arranged radially along the centerline of the main shaft.
