FIELD: technological processes.
SUBSTANCE: invention relates to a device for the work hardening of the inner surface of metal pipe products. In the method, the device contains a roller matrix installed with the possibility of linear reciprocating movement relative to the axis of the workpiece, and a screw bush installed inside the tubular product. At least one deforming roller and at least two smoothing rollers are attached to the sleeve. Said sleeve is mounted on a running screw placed between the supports on the bearings with the possibility of rotation around its axis, and attached with strings to prevent radial rotation.
EFFECT: as a result, the product range is expanded.
