FIELD: process engineering.
SUBSTANCE: invention relates to hot deep drawing and can be used for setting of metal sheets deformation parameters. Several cycles of tests for maximum drawing under isothermal conditions are performed to plot the graph "maximum drawing-test temperature" and to define the parameters of technological process or fitness of tested sheet specimen. Proposed device comprises chamber to house heaters, top thermal rod fitted on axle whereto rigidly secured is die case to receive tested specimen and thermal insert, male die with spherical surface is arranged at bottom thermal rod to be displaced axially by the drive.
EFFECT: higher precision, lower labor input is quality control.
