DEVICE FOR THERMAL CUTTING OF NONROTATORY PIPES OF LARGE DIAMETER Russian patent published in 1996 - IPC

FIELD: pipe rolling. SUBSTANCE: device has frame 1 with driving device 2 for cutting with oxyacetylene torch placed in gaseous dust collector 3, approach table 4 with chute 5, take-in table 6 and mechanism for removing cut rings made in the form of movable capture 7. Transport roll train 8 is mounted perpendicular to approach table 4. The mechanism for pipe holding is assembled on truck 9 movable relative to longitudinal axis of approach table 8. Approach table 4 and device for removing rings are mounted on frame 1. Receptacle 10 of scale and seam is placed on take-in table 6 mounted for displacement relative to longitudinal axis of transport roll train 8. When pipe 39 goes to approach table 8 truck 9 moves upon the back face end of pipe 39 and mechanism for pipe holding actuates. The pipe is fed to cutting zone. With the help of capture 7 the cut ring is fed to transport roll train 8 with the aid of which it is delivered to following operation. EFFECT: reduced losses of time during pipe cutting. 1 cl, 2 dwg
