Insulating die plate, forging press and ceramic insulating body

A forging press (10) for pressing a semi-finished product (15) in one pressing direction (17) comprising:

• a press tappet (12);
• at least one drawbar (14);
• at least one upper die (20);
• at least one lower die (30);
• wherein each of the dies (20, 30) comprises
• a cold die part (25, 35), and
• a hot die part (26, 36),
• wherein each of the dies (20, 30) comprise an insulating layer (21, 31) arranged perpendicular to the pressing direction (17),
• wherein the insulating layer (21, 31) is respectively arranged between the cold die part (25, 35) and the hot die part (26, 36),
• wherein each of the insulating layers (21, 31) is arranged between a cold cover side (23, 33) situated on the side of the cold die part (25, 35) and a hot cover side (24, 34) situated on the side of the hot die part (26, 36),
• wherein the insulating layer (21, 31) comprises ceramic insulating bodies (40),
• wherein an insulating body plane (22, 32) arranged at least parallel to the end plates (27, 28, 37, 38) is defined for the insulating layer (21, 31),
• wherein the insulating bodies (40) are arranged spaced apart next to one another on the insulating body plane (22, 32), whereby, on the insulating body plane (22, 32) between insulating bodies (40), intermediate spaces (41) are formed,
• wherein a total area of the insulating layer (21, 31) comprises at least surface portions of the insulating bodies (40) and surface portions of the intermediate spaces (41),
• wherein a plurality of insulating bodies (40) are arranged in each insulating body plane (22, 32),
• wherein, in each section through the insulating bodies (40) parallel to the insulating body plane (22, 32), a surface portion of the insulating body (40) in the total area of the insulating layer (21, 31) is at least 50%, and wherein the insulating bodies are symmetrically formed,
• wherein the top side of the insulating body is equal to the bottom side of the insulating body and all insulating bodies are designed as plates,
• wherein the plates (42) have a height and a maximum width (43) and are wider than their height, and
• wherein within the insulating layer (21, 31) ceramic insulating bodies (40) are arranged on at least two insulating body planes (22, 32).
