FIELD: plastic metal working, possibly by isothermal deforming. ^ SUBSTANCE: apparatus includes die unit, heating device and heat insulation unit. Heating device includes two sections arranged at both sides of die unit and bridge. Each section includes upper and lower electrically conducting plates electrically connected one to other through lamellae. Said sections are electrically connected in series; bridge is arranged outside heat insulation unit. Apparatus may have members for fixing electrically conducting plates. Several fixing members provide possibility for moving electrically conducting plates. ^ EFFECT: uniform heating of die set, lowered metal consumption for communications. ^ 2 cl, 4 dwg |
