Hot formed coiling machine

A hot coiling machine comprising:

• a center roll configured to rotate by a rotational force generated from a drive unit;
• a feeding roll disposed near the center roll and having an external surface facing an external surface of the center roll, the feeding roll being configured to move close to or away from the center roll by a first positioning unit and being rotated by the rotational force generated from the drive unit thereby moving a wire together with the center roll;
• at least one forming roll for forming the wire transferred by rotations of the center roll and the feeding roll into a coil shape;
• a pitch control unit disposed near the at least one forming roll to come into contact with the wire exiting the at least one forming roll and configured to push a lateral surface of the wire exiting the at least one forming roll to provide the wire with a pitch;
• and
• a bending unit for pushing a leading end of the wire fed between the feeding roll and the at least one forming roll to bend the leading end of the wire in a turning direction of the wire,
• wherein the bending unit comprises
• a bending pusher rotatably fitted over a rotating shaft of the at least one forming roll positioned near the feeding roll,
• a spring configured to restore the bending pusher to an initial position by an elastic force during bending of the wire by the bending pusher, and
• a bending actuator for pressing a lateral surface of an end of the bending pusher to rotate the bending pusher about the rotating shaft and thereby bending the leading end of the wire.
