REINFORCING BAR BENDING MACHINE AND REINFORCING BAR WORKING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a reinforcing bar bending machine by which the positional adjustment of a forcing point roller accompanied by the replacement of a supporting point roller is performed simply.;SOLUTION: A bending base 1 in the attitude along the vertical direction is provided and also a bending part 2 for bending the reinforcing bar by making its surface move on the bending base 1 is provided. The supporting point roller 3 is provided in the bending part 2 and also a drive and rotation supporting part 5 which is attached so as to drive and rotate the forcing point roller 4 around the axial center of the supporting point roller 3 is provided, the supporting point roller 3 is attached so as to be freely replaced with a supporting roller with different diameter, a plurality of roller installing holes 9 for supporting and fixing by inserting the rotary supporting shaft of the forcing point roller 4 are arranged around the supporting point roller 3 on the driving/rotating supporting part 5 and the plurality of the roller installing holes 9 are respectively varied in the distance from the axial center of the supporting point roller 3.;COPYRIGHT: (C)2011,JPO&INPIT
