Abstract
FIELD: power energetics and other branches of machine engineering, namely head for knurling by rollers multistart helical different-profile surfaces on cylindrical blanks, particularly on tubular blanks, for increasing heat exchange surface area of tube bundles of heat exchangers. SUBSTANCE: head is provided with mechanism for dynamic automatic feed of rollers by depth of profile to be formed at knurling process. Said head is provided in addition with friction mechanism for automatic feed of rollers, device for setting feed stroke, apparatus for automatic disengaging mechanism for automatic roller feed after finally setting feed stroke by depth of formed profile. Mechanism for dynamic automatic roller feed is in the form of yoke having non- balanced inertia weight rotating around head body and provided with system of jointly connected drive tie rods with couplings for rotating rollers eccentrically arranged on trunnions. Said rollers have stoppers for fixing rotation angle of yoke after setting feed stroke. Mechanism for friction automatic roller feed is used at knurling helical surfaces on blanks having lowered ductlity and increased deformation resistance. Said mechanism is in the form of frictional ring halves engaging with outer surface of blank and it is disconnected when feed stroke setting is over. With used of such head mutlistart helical surfaces having any number of starts of different profiles and depth values may be knurled. EFFECT: enlarged using range of head.
