DEVICE FOR SUPPORTING ARM OF BENDING ROLLER IN REINFORCING BAR BENDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a device for supporting the arm of the bending roller in a reinforcing bar bending machine with which the pressing force of the bending roller is equalized and also, even in the case that many bars are bent at the same time, all the reinforcing bars are bent at an accurate bend angle. ;SOLUTION: The center shaft 4 on the front outer peripbery of which the center roll 3 is fixed is freely slidably inserted into the inside of a rotatable cylindrical shaft 1. The arm 18A on one side of a bending roller 17 is fixed to the rotatable cylindrical shaft 1. In front of the arm 18B on the other side of the bending roller 17, a ring-shaped rotatable shaft 19 is fixed. The rotatable shaft 19 is rotatably fit into a bearing 16 which is provided on the front wall 13 of a flanged bush 11 or the frame 12 of the bending machine.;COPYRIGHT: (C)2001,JPO
