Pressure system of double-steel-belt isobaric press

The utility model belongs to the technical field of plate production equipment, and discloses a pressure system of a double-steel-belt isobaric press, which comprises a heating system and a cooling system. A first sealing cavity is formed among upper and lower hot pressing plates and upper and lower steel belts of the heating system, and is filled with a heat-conducting pressurized fluid medium to form a hot pressing area; a second sealing cavity is arranged between the upper and lower cold pressing plates of the cooling system and the upper and lower steel belts, and a cooling and pressurizing fluid medium is injected into the second sealing cavity to form a cold pressing area; the first sealing cavity and the second sealing cavity are each divided into a plurality of sub-cavities through sealing strips, the sub-cavities of the first sealing cavity and the second sealing cavity are equal in pressure, and the temperature is distributed in a gradient descending mode. According to the utility model, isobaric pr
