CUTTING PLATE FOR MACHINING ARTICLES COMPRISING ELASTIC COMPONENTS Russian patent published in 2013 - IPC B02C18/18 B29B17/04 

FIELD: process engineering.

SUBSTANCE: invention relates to disposal of wastes, particularly, worn-out tires. Cutting plate for machining articles with elastic components that have teeth of trapezoidal cross-section gradually decreasing toward the end and tooth bases to form rear angle. Opposite faces have equal number of teeth while teeth on adjacent faces are smaller by one. Teeth of said faces are located at points corresponding to positions of recesses at faces with larger number of teeth. Front surface of teeth is corrugated with alternating trapezoidal-cross-section ledges and recesses, said cross-section being inclined at sides at front clearance angle. The number of teeth is odd while medium ledge is higher than lateral ledges. Front surface has a break changing in plane parallel with stepped plate hole axis. Larger diameter hole step equals fastening bolt head diameter while hole depth makes, at least, bolt head and has flat ledge corresponding to bolt head wrench seat. Support surface has elements that allow reliable location at holder thrust surface.

EFFECT: longer life.
