FIELD: forging processes and equipment, possibly manufacture of large-size rings and shells whose outer diameter exceeds spacing between columns of press. ^ SUBSTANCE: method comprises steps of upsetting, piercing and expanding on mandrel. After expanding, forged blank is subjected to radial upsetting by value no less than D - B where D -outer diameter of forging, B - inter-column spacing of press in direction normal to forging axis in order to form oval-shaped blank. Oval bank is tilted by 90° around its lengthwise axis and turned by 90° around vertical axis. Then forged blank is subjected to secondary radial upsetting by the same value for forming round blank. ^ EFFECT: possibility for making forged rings in standard equipment without using additional special attachments. ^ 5 dwg, 1 ex |
