DEVICE FOR BENDING ZIGZAG ITEMS OF BAND OR WIRE WORK PIECES Russian patent published in 2011 - IPC B21F1/04 B21F45/00 

Abstract RU 2425727 C1

FIELD: machine building.

SUBSTANCE: device consists of base, of carriers mounted on it, of drive of their turn and of bending rollers interconnected with carriers. It is equipped with a pair of opposite bending modules positioned on the base in horizontal case borings of which there are located shafts. The shafts are interconnected with the drives of their rotation. Also, the device is equipped with sliders. On axes of the sliders there are mounted the said bending rollers. The device is further equipped with a mechanism of position stabilisation in vertical plane at formed item bending. Each carrier is made in form of cantilevers secured at ends of the shafts; the said sliders with bending rollers are arranged on cantilevers. The shafts are mounted with set off one relative to another, while their axes are parallel. Cams controlling angles of turn of the shafts are arranged on opposite ends of the said shafts; the cams interact with pneumatic turning devices through an intermediate link.

EFFECT: increased reliability; improved conditions of operation and maintenance.
