FORGING PRESS OF THE HOT-DIE TYPE AND THERMAL INSULATION MEANS FOR THE PRESS

摘要

The invention relates to a forging press of the hot-die type with an operating temperature above a temperature T, comprising two dies (7, 8) between two die support elements (4, 5), a thermal insulation means (6, 6') being placed between each die (7, 8) and its support element (4,5). The press is characterized in that the said means (6, 6') comprises at least two superposed layers (A, B) , a first layer (A) comprising a first material having mechanical and thermal properties suitable for operation at a temperature above the temperature T, a second layer (B) comprising a second material having mechanical and thermal properties suitable for operating at a temperature below the temperature T, the thermal conductivity of which is lower than that of the first material and is approximately equal to 0.2 W/m.K, with a tolerance of 10%. Thanks to the invention, it is possible to obtain an effective thermal insulation means of small thickness.
