FRAMELESS MICRO SPIRAL WINDING MACHINE Russian patent published in 2025 - IPC B21F3/04 

FIELD: performing operations.

SUBSTANCE: invention relates to production of micro-spirals and can be used in devices for winding frameless micro-spirals by deformation of wire during its winding onto a mandrel. Machine comprises bed, coil with wire, wire feeder, spindle and wire winding tooling. Machine comprises a stand-mounted power supply, a data input device, a screen for outputting information, a programmable control unit connected to the stepper motors, clamping tab connected with actuator of clamping tab opening with possibility of synchronous operation with spindle and tooling for wire winding and providing clamping of wire to said tooling during wire winding. Cutting unit is made in the form of blades and a blade servo motor. Wire drawing device is made in the form of centring device with felt material and tensioner located on its surface. Wire feeder is made in the form of a carriage and a ball-screw gear. Spindle and tooling for wire winding are located coaxially and installed in bed with possibility of rotation.

EFFECT: obtaining microspirals with stable geometry and dimensions during mass production, including from wire with thickness of 0.01 mm.
