Bending reinforcing steel into stirrups - using wire straightening unit with one group of driven rollers one group of movable rollers

摘要

The device bends lengths of reinforcing steel wire, drawn from a coil, into stirrups. It has a wire transporter, with a straightening unit(18,23) of several rollers(19,20). There are a wire advance unit with drive, a cutter device(26), and a bending station with tools(27,31,44). The rollers of the straightening unit are located in groups, and the wire passes between the groups. The rollers(20) of one group only are driven. The other rollers(18) are freely moveable about an axis, which is at right angles to their rotary axis. These rollers are carried on a bearing support(21), which is moveably fastened on the machine frame(17). The coil is located on a carrier(7), which is turnable about a horizontal axis. USE/ADVANTAGE - Bending lengths of steel wire into reinforcing stirrups with reduced construction resulting in improved working method.
