DEVICE FOR PRODUCING RECTANGULAR CROSS SECTION TUBES Russian patent published in 2011 - IPC B21C37/15

Abstract RU 2428270 C1

FIELD: process engineering.

SUBSTANCE: proposed device comprises two supports with hydraulic cylinders articulated therewith. That hydraulic cylinders are incorporated with four forming lines arranged perpendicular to form rectangular cross section on axis of supports. Tube rear end face features no distortion of roundness and wastes are reduced due to arrangement of forming lines that allows crosswise and lengthwise travel. Note here that aforesaid crosswise and lengthwise travel hydraulic cylinders are articulated with one of foundation supports and crosswise travel hydraulic cylinders are articulated with another foundation support.

EFFECT: expanded performances, metal savings.
