Press jig for thermomechanical analysis of powder during uniaxial compression

摘要

The press jig is designed for thermomechanical analysis of the properties of the powdered material during its uniaxial compression. The jig consists of a die (1) and an upper press piston (2), further comprising a lower press piston (5) with a lower axial force sensor (7) mounted on a press holder (8). The side pressure piston (9) of a radial force sensor (11) radially extends through the die (1) into the space between the upper press piston (2) and the lower press piston (5) and the thermocouple (4) extends axially through the lower press piston (5). A spacer washer (6) is provided between the lower pressing piston (5) and the lower axial force sensor (7). The radial force sensor (11) is fastened by a screw (13) in a holder (12) which is anchored to the press holder (8). A bias bolt (10) is provided between the radial force sensor (11) and the side pressure piston (9).
