PROCESSING OF GILLS OF POWER CYLINDERS BY HYDROCYSTALS OF AGRICULTURAL

MACHINES

The progressive process of processing deep openings of machine parts type sleeves on the basis

of combined deformation - cutting forecasting is described.

It has been shown that the optimal variant of the shell aperture processing is deformation -

cutting stretching. During the work of the deforming part of the tool, the structural and low-alloyed

plastic steels receive cold deformation strengthening. This reduces the intensity of build-up during cutting

and improves the handling of the latter. A model of the interrelation of phenomena when cutting metal

strengthened by cold deformation was constructed. The new construction of a combined deformation - a

cutting tool for processing cylinder liners of hydraulic cylinders, as a power executive body of agricultural

machinery hydrosystems, was developed and tested in production conditions.

Key words: shell, hydrocylinder, stretching, cold deformation strengthening, growth, deep hole.
