METHOD OF STATIC-PULSE REELING OF INTERNAL GROOVES Russian patent published in 2006 - IPC B23P6/00 B24B39/02 

FIELD: finishing-strengthening treatment of grooves.

SUBSTANCE: surface to be treated is subject to normal influence of static and periodical pulse load by means of treatment unit provided with mandrel. Treatment unit is used which has radial located plungers, deforming instruments fixed onto plungers, screw cylindrical compression spring and control ring equipped with handle. Mandrel has central longitudinal hole where waveguide and block head, in form of rods, are disposed. Screw cylindrical compression spring is mounted at free end of waveguide. Surface of waveguide is made in form of cone and is disposed to have contact with rolling bearings made in form of expanded balls, which bearings are mounted at free ends of the plungers. Flat spring is made in form of wave ring. Pins for acting onto waves of mentioned wavering are mounted art edge of the control ring. Periodical pulse load is applied by means of block head which acts on waveguide. Static load is applied due to deforming tools by means of wave ring. Deforming instruments are withdrawn out of groove to be treated due to turn of control ring by means of handle.

EFFECT: widened technological abilities of static-pulse treatment.
