DEVICE FOR COLD-WORK STRENGTHENING OF INTERNAL SURFACE OF HOLLOW AXISYMMETRIC BLANKS

摘要

FIELD: machine building.SUBSTANCE: device contains a support and two or more deforming elements in form of the cone rollers adjacent to the support and held against fall out by the cage carrier. At least one roller is made with ring shoulder. The support is made composite containing axis with cone stop shoulder supporting the side of rollers with larger diameter, and cone support ring supporting the end of rollers with smaller diameter. Cone support ring is installed with possibility of rotation against axis.EFFECT: simplified design of device and increased service life of the device.2 dwg, 1 ex
