Abstract
A mechanism for producing coil springs (10) includes a winding stage (110) for engaging with a wire (20) and deforming the wire (20) to coil windings as the wire (20) moves through the winding stage (110). Further, the mechanism comprises a feed mechanism (120) configured to feed the wire (20) to the winding stage (110). Further, the mechanism comprises a rotary cutter (130). The rotary cutter (130) is configured to cut the deformed wire (20) into portions forming separate coil springs (10) and a blade (135) which is driven for rotation about a stationary rotation axis.
Claims15
A mechanism for producing coil springs, the mechanism comprising:
- a winding stage for engaging with a wire and deforming the wire to coil windings as the wire moves through the winding stage;
- a feed mechanism configured to feed the wire to the winding stage;
- and
- a rotary cutter configured to cut the deformed wire into portions forming separate coil springs;
- wherein the rotary cutter comprises a blade which is driven for rotation about a stationary rotation axis,
- wherein the blade comprises a protrusion configured to engage between two coil windings of the deformed wire and separate the two coil windings as the blade rotates.
(canceled)
A method of producing coil springs, the method comprising:
- feeding a wire to a winding stage;
- engaging the wire in the winding stage to deform the wire to coil windings as the wire moves through the winding stage;
- and
- by a blade rotating about a stationary rotation axis, cutting the deformed wire into portions forming separate coil springs,
- wherein the blade comprises a protrusion configured to engage between two coil windings of the deformed wire and separate the two coil windings as the blade rotates.
