Description

[Brief explanation of drawings]

Fig. 1 is a plan view showing end bending work of a roll bending device according to an embodiment of this invention, Fig. 2 is a plan view showing full arc bending work of this invention, and Fig. 3 shows a conventional roll bending device. The perspective view and FIG. 4 are plan views showing central arc bending work. 2 is a drive roll, 3 is a push roll, and 7 is an elastic member roll. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] A push roll is rotatably supported at both ends vertically on a table-shaped device main body, and is movable in a direction perpendicular to the axis. an elastic member roll rotatably supported coaxially with the roll; and an elastic member roll coaxially coaxial with the push roll that faces equidistantly on both sides in a perpendicular direction with the movement line as a starting point on the other side of the movement line of the push roll. and a drive roll whose both ends are pivotally supported so as to be rotatable.The end bending of the member to be formed is performed by the push roll and the elastic member roll, and the other circular arc bending of the member to be formed is performed by the push roll and the above. A roll bending device characterized by a drive roll.
