Abstract

The pipe bending machine for large diamter pipes produces pipe bends without thinned-out walls. The bending mechanism is mounted on a shaft and works in conjunction with an eccentric jaw clamp and a set of discs and traction elements, which cannect the bending mechanism with a feed mechanis. The discs are arranged on either side of the clamping device. The distance between the centreline of the shaft and the area of contact of the traction element with the disc exceeds the distance between the shaft centre- line and the centre of the clear width between the effective surfaces of the jaws, when the latter are closed.
