PLANT FOR HARDENING OF EXTRUDER SCREWS BY DIFFUSION BORATING IN COATINGS BY HEATING WITH HIGH-FREQUENCY CURRENTS Russian patent published in 2024 - IPC C23C8/70 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural production, namely to plant for hardening of working bodies of agricultural machines for animal breeding, and can be used both at small farms and at large agricultural enterprises. Installation includes a bed placed on the supports of the moving device, bearing assemblies, the main screw driving, according to the principle of a ball-screw pair, a table, stepper motor mounted on the subframe, driving the main screw through the coupling, quick-detachable connection, at the same time the installation is additionally equipped with a frequency converter installed on the bed, to which an induction heater is directly connected and a tank with a submersible pump for cooling liquid, providing the cooling liquid circulation through the pipelines connecting the tank and the induction heater with the frequency converter, performing the induction heater cooling, in addition, for cooling and tempering hardened screw, plant is equipped with oil tank, at that, the quick-release connection, which provides fixation of the hardened screw of the extruder, is equipped with a tilting device, which realizes the timely disconnection of the hardened screw, and control of electronic components of the installation is provided by a control panel.

EFFECT: increasing the service life of the extruder screw by obtaining a wear-resistant hardening coating on the working edge of the extruder screw.
