HAND PIPE BENDER Russian patent published in 2014 - IPC B21D9/05 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming particularly to pipe bending and can be sued for repair and construction. Flanged bending gage and reeling roll have teeth cut over cylindrical surface to displace reeling roll over bending gage are interconnected by two plates to run there between for interaction of roll teeth with those of banding gage. Note here that bending gage and reeling roll have central square-shape bores with cylindrical ledges made there around while two square-shape bores are made at plate ends to receive ledges and to connect said plates with reeling roll and bending gage designed to accommodate the tools for rotation of reeling roll over the bending gage.

EFFECT: lower applied forces and costs.
