摘要

FIELD: machine building.;SUBSTANCE: proposed device comprises manual press with specimen arranged thereon and prepared by filling metal pattern with cylindrical opening with premade clay paste, and stiff top and bottom dies. Said pattern is made up of thin-wall cylinder with larger-diameter bottom. Said dies represent shot cups with perforated bottoms. Bottom die bottom has ring-shaped ledge. Pattern is furnished with smaller inner diameter ring passed there through to rest upon said die bottom ring-shaped ledge to rotate thereabout in cycles to align calibrated 3.2 mm-dia hole made in ring wall with similar hole made in pattern wall for periodical formation of bundle of clay paste to be controlled. Manual press is made up nut and screw, nut representing central threaded opening in crossbar. Elongated screw is furnished with lever on upper end and centering skid on lower end aligned with recess formed on top die bottom inner surface.;EFFECT: reduced labour input, faster determination of elastic limit, reliable and stable data.;3 cl, 10 dwg
