Abstract
A machine and method according to which advancing material (1) such as wire, prismatic material, or rod is gripped during the duration of its advancement from an advancement unit (2) towards a bending unit (3). The gripping is effected by a jaw (4) that grips material (1) with sufficient force so that the material (1) cannot twist. By gripping the advancing material (1), the under-production part (16) is simultaneously gripped and prevented from rotating, so that bends are made in the correct plane and the bent product is produced with great accuracy.
Claims19
A bending machine preventing torsion in wire, comprising:
- a bending unit configured to bend wire;
- an advancement unit configured to advance wire to said bending unit;
- an antitorsion jaw assembly disposed between said advancement unit and said bending unit;
- a carrier configured to carry said antitorsion jaw assembly;
- said carrier being movably supported on a guide;
- a return mechanism configured to bias said carrier in the direction towards said advancement unit;
- said antitorsion jaw assembly is configured to grip advancing wire to pull along said jaw assembly, said carrier, and said return mechanism;
- and,
- a motor configured to actuate said antitorsion jaw assembly to grip wire.
A bending machine preventing torsion in wire, comprising:
- a bending unit configured to bend wire;
- an advancement unit configured to advance wire to said bending unit;
- an antitorsion jaw assembly disposed between said advancement unit and said bending unit;
- a carrier configured to carry said antitorsion jaw assembly;
- a first jaw piece, said first jaw piece having a portion extending through said carrier;
- and,
- a second jaw piece extending from above said carrier;
- and,
- a motor connected to said portion and configured to actuate said first jaw piece to grip wire between said first jaw piece and said second jaw piece to result in said antitorsion jaw assembly and said carrier being pulled along by advancing wire.
An antitorsion assembly for a bending machine, comprising:
- an antitorsion jaw assembly configured to grip wire against torsion;
- a carrier configured to carry said antitorsion jaw assembly;
- a guide configured to movably support said carrier;
- a return mechanism configured to pull said carrier in a first direction along said guide;
- and,
- a motor configured to activate said antitorsion jaw assembly to grip advancing wire to pull along said jaw assembly for passively advancing said antitorsion jaw assembly and said carrier in a second direction along said guide.
