[CN 201610239394.5] Heating and heat preservation system and operation method of isothermal thermoforming hydraulic press Title: Heating and heat preservation system and operation method of isothermal thermoforming hydraulic press Application No.: CN 201610239394.5 Applicant: Tianjin Tianforging Press Co., Ltd. Application Date: 2016-4-15 Patent Type: Invention Application The present invention relates to a heating and heat preservation system and operation method of isothermal thermoforming hydraulic press, including an upper heating platform, a lower heating platform and a heat preservation door, the upper heating platform and the lower heating platform include water cooling plate, heat insulation ceramics, multiple pressure-bearing ceramics, alloy steel heating tables, heating tubes and thermocouples. The alloy steel heating tables of the upper heating platform and the lower heating platform are provided with multiple independently controlled heating zones, and each heating zone is provided with independently controlled electric heating tubes, temperature measuring thermocouples and temperature protection thermocouples. The advantages are: the heating tubes independently controlled inside the alloy steel heating tables of the upper heating platform and the lower heating platform are energized for zone heating, and the thermocouple is used to detect the separate heating areas and adjust the temperature difference of each heating area at any time, so as to ensure that the temperature difference of the entire working area of the hydraulic press is less than the tolerance value and the uniformity of the temperature in the upper and lower heating platforms, and ensure the processing quality of the workpiece. Greatly save energy and reduce production costs, shorten the processing cycle, improve production efficiency.
