装置。 A heating chamber is provided in a container provided inside the frame, and a heater is provided within the heating chamber. A cylindrical mold filled with a powder sample is placed inside the heating chamber, and push rods are placed at the top and bottom of the mold, respectively. In a hot press device configured to insert the tip, press the powder sample in the mold with the push rods, and heat-treat the sample while applying pressure, the push rods are inserted into the frame by operating the rods. A hydraulic cylinder is provided to press the hydraulic cylinder, and the hydraulic cylinder is equipped with a controller to control the supply path and amount of hydraulic pressure to the hydraulic cylinder, and a controller to detect the value of the hydraulic pressure supplied to the hydraulic cylinder. By doing so, a pressure detector for detecting the value of the pressing force applied to the sample and a position detection mechanism for detecting the position of the rod are integrated, and
A hot press apparatus comprising a control device that controls the operation of the controller based on the detection results of the pressure detector and the position detection mechanism.
