AUTOMATIC CUTTER FOR SURFACE OF TANK

摘要

PURPOSE: An automatic cutter for a surface of a tank is provided to increase cutting efficiency, to cut the surface regardless of the diameter of a perforation hole, and to reduce cutting time. CONSTITUTION: In an automatic cutter placed on an outer peripheral surface of a flange(9) formed on a surface of a tank(10) to cut the tank surface, the cutter is composed of a body(1); a first guide roller(3) having a fixing bar(2) at the upside and contacting with a side of the outer peripheral surface of the flange to rotate, and the fixing bar formed at a side of the body; a second guide roller(4) confronting the first guide roller, having a sliding bar(11) slidably formed at other side of the body, and contacting with other side of the outer peripheral surface of the flange to rotate; a torch clamp(6) slidably formed in the middle of the body and combined with a torch(5); and a motor(8) installed at a side of the fixing bar. The motor receives power by being coupled with a battery case(7) which is arranged at the upside of the body and transmits driving force to the first and second guide rollers.
