DEVICE FOR SURFACE PLASTIC DEFORMATION PROCESSING WITH EXTERNAL SPRING Russian patent published in 2008 - IPC B24B39/04 

FIELD: technological processes.

SUBSTANCE: device contains working deforming elements as coils of spiral spring for stock processing with pull and casing with immovable cover and cover, which is installed with the possibility of rotation. One end of spiral spring is rigidly fixed in the immovable cover. The other end of spiral spring is movingly installed in the cover installed with the ability of rotation so that it is possible to wind and unwind the spiral spring by means of handle and ratchet-gear. The spiral spring is realized under the condition of radial motion provision with internal diameter of its coils that is less than diameter of processed sphere for the value of double pull. The spiral spring is arranged with ability to insert the stock in the openings of its coils in order to provide the contact of spiral spring coils internal surface with the stock and in order to embrace the stock.

EFFECT: device cost is reduced and design simplicity is achieved.
