Abstract

A flexible roll forming device is provided. The roll forming device includes bases respectively disposed on opposite sides with respect to a process direction center line in a left/right direction of which rails are configured thereon along a lateral direction of the process direction center line, and upper and lower forming rolls configured to vary both positions in the lateral direction of processing, and angles from the process direction.

First claim

What is claimed is:

1. A flexible roll forming device comprising:
at least two bases having a gap therebetween, each of which respectively disposed on opposite sides with respect to a process direction center line,
a rail configured on each of the at least two bases along a lateral direction perpendicular to the process direction center line;
a forward/backward moving means having a slide plate provided to be movable along the rail, and a forward/backward moving cylinder mounted on each of the at least two bases connected to the slide plate with an operation rod;
a turning means rotatably provided on the slide plate on each of the at least two bases so as to provide an angular movement away from the process direction center line; and
a roll forming means provided on the turning means to include an upper forming roll and a lower forming roll inclined with respect to the upper forming roll for subjecting a material fed thereto to flexible roll forming by using the upper and lower forming rolls while varying positions in the lateral direction with the forward/backward moving means, and angles from the process direction center line with the turning means,
wherein the turning means further includes a turning reducer mounted to a center of the slide plate;
a turning motor mounted under the turning reducer for supplying a torque; and
a turntable mounted over the turning reducer so as to be turned by the torque from the turning motor.

2. The roll forming device of claim 1 , wherein:
mounted on the slide plate,
for sensing a sensing dog mounted on one side of an underside of the turntable to sense a home position of the turntable with respect to the slide plate, and rotation limit positions in one direction and the other direction and forwarding a signal thereof.

3. The roll forming device of claim 1 , wherein a space portion is formed within each of the at least two bases for the turning motor to be moved without interruption when the forward/backward is operated.

4. The roll forming device of claim 1 , wherein:
the roll forming means includes:
upper and lower plates;
roll posts coupled to the upper and lower plates mounted to the turning means;
upper and lower roll housings mounted to the roll posts to be movable in up/down directions; and
a lower roll motor mounted to an outside of the lower roll housing connected to the lower forming roll passed through the lower roll housing.

5. The roll forming device of claim 4 , wherein:
the upper forming roll is rotatably connected to a rotating bracket fixed to the upper roll housing through a slanted shaft, and has forming surfaces corresponding to an external circumferential surface and a side surface of the lower forming roll.

6. The roll forming device of claim 4 , further comprising adjusting bolts
provided between the upper and lower plates and the upper and lower housings for adjusting and securing positions of the upper and lower roll housings, respectively.
