Gripping arm for the changing of bending tools in a tube-bending machine incorporating a tool store mounted on a frame above the bending machine

摘要

The gripping arm consists of a gantry (17) placed around the bending machine (1) above the bending head (3) and the bending arm (4). A rotating head (33) having independent movement in relation to the gantry (17) has two rotations, dependent or independent, with movement in the horizontal and vertical planes. A magazine for holding tools (42) can move independently in relation to the rotating head (33) in a horizontal direction or can rotate in relation to the gantry.
