Abstract

A solution is suggested for the problem of juxposing the compressibility and compression curves of a powder in a system of three coordinates and representing in three projections the deformation of the powder as a function of the pressing pressure and time and the pressure as a function of the time with preliminary calculation and plotting of the dependence of the deformation rate on the pressing pressure. The calculations and the plots in the three projections are presented for pump drives with a constant and variable capacity and for a pump-accumulator drive. Three calculation variants are given for each drive type, depending on the duration of the cycle and the pressing rate. It is recommended that drives with updated high-speed axial-piston pumps of variable capacity be used.
