Description

Technical Field

[0001] This utility model relates to the field of torsion spring processing technology, specifically a CNC machining equipment for variable diameter torsion springs. Background Technology

[0002] Torsion springs are among the most complex in design principle of all spring types, with a wide variety of forms, making their design theory the most intricate. Torsion springs belong to the helical spring family. The ends of a torsion spring are fixed to other components; when these components rotate around the spring's center, the spring pulls them back to their initial position, generating torque or rotational force. Torsion springs can store and release angular energy or statically fix a device by rotating a lever arm around the spring's central axis. These springs are typically tightly wound, but there is a pitch between the coils to reduce friction. They resist rotational or rotational external forces. The direction of rotation (clockwise or counterclockwise) of the torsion spring is determined by the application requirements. The coils can be tightly wound or loosely wound to withstand torsional loads (perpendicular to the spring axis). The ends of the spring can be wound into hooks or straight torsion arms.

[0003] Existing torsion spring manufacturing primarily achieves multi-turn winding of the torsion spring by controlling the wire release mechanism. However, this method requires a clamping mechanism to fix the end of the wire to the winding pin, resulting in a complex structure and complex, error-prone operation. Utility Model Content
