Pressing jig for thermo-mechanical analysis of powdered material during uniaxial compression

摘要

Pressing jig is aimed for the thermo mechanical analysis of the properties of the powdery material during the uniaxial compression. The jig is formed by a die (1) and a upper pressure piston (2), and further comprising a lower pressure piston (5) with a sensor (7) of the lower axial compression force located on a pressure holder (8). In the space between the upper pressure piston (2) and the lower pressure piston (5) through the die (1) radially extends a piston (9) of the side pressure of a sensor (11) of the radial force and through the lower pressure piston (5) axially extends a thermocouple (4). Between the lower pressure piston (5) and the sensor (7) of the lower axial force is placed a spacer ring (6). The sensor (11) of the radial force is attached by a screw (13) in a holder (12), which is anchored to the pressure holder (8). Between the sensor (11) of the radial force and the piston (9) of the side pressure is included a bias screw (10).
