Embodiment 1
[0025] like figure 1 A torsion spring driven torsion device shown includes a push rod driving device 2 and two ends of the processing device 3; the driving end of the push rod driving device 2 is connected with the two ends of the processing device 3; The steel ends are in contact.
[0026] The product flow direction of the torsion spring is: the push rod driving device 2 to the processing device 3 at both ends.
[0027] like figure 2 Shown is a schematic diagram of the product structure of the spring steel a folded in half. After being folded in half, the spring steel a includes a folded end b and an open end c. The feeding and clamping device 1 clamps the folded end b, and the processing devices 3 at both ends are in contact with the two sections of spring steel bent at the open end c respectively to process them. .
[0028] like figure 1 As shown, the push rod driving device 2 includes a driving motor 21, a bearing housing 22, a driving shaft 23, a driving cam 24, a f...

Description
technical field [0001] The invention relates to the field of torsion spring processing, in particular to a driving device and method for a torsion spring processing push rod and a driving torsion device. Background technique [0002] Torsion springs are coil springs. The ends of a torsion spring are secured to other components, and as the other components rotate about the center of the spring, the spring pulls them back to their original position, creating a torque or rotational force. Torsion springs can store and release angular energy or statically fix a device by rotating a moment arm about the central axis of the spring body. These springs are usually close-fitting, however, the coils are spaced to reduce friction. They create resistance to rotation or rotational external forces. According to the application requirements, the direction of rotation of the torsion spring (clockwise or counterclockwise) is designed to determine the direction of rotation of the spring. ...
