A method of manufacturing hollow bodies of revolution having a shaped lateral surface (such as a tractor track roller) by surface heating of a roller blank in an inductor on a hollow mandrel with a cooled core that prevents through heating of the billet of the roller, and subsequent rolling of this billet in the centers, between two converging and rotating profile rolls

摘要

FIELD: transportation.SUBSTANCE: surface heating of the workpiece of the tractor compactor in the HDTV inductor and subsequent rolling of the workpiece in the centers between two approaching and rotating profile rolls. In this case, the surface heating of the billet is carried out to a temperature of 1200±50°C to a depth 30 mm on a hollow mandrel with a cooled core, preventing through heating of the workpiece. Rolling of the workpiece is carried out in profile rolls rotating at a speed of 35 rpm.EFFECT: expanding technological capabilities.3 dwg
