Cylindrical workpiece 1 is installed on deforming module 2, is made integral with the cavity 3, which is hosted environment (magnetic fluid) 4. In the cavity 3 is also placed hollow gravitational resonator 5 partially filled with medium (magnetic fluid) 6. The cavity 3 is it 8 with the annular groove 9 on the working surface down to the workpiece so so in the annular groove 9 of the plug 8 reglamentirovannyj was part of the annular projection 10, is made on the working surface of the die 11, forming in connection with the presence of a medium (liquid) 12 relaxer elastic stresses.After the force-closure workspace of the zone of deformation: the punch 8-blank 1-matrix P-module 2-plunger 7, produce a regulated end draught procurement and subsequent run-in plug 8 (Fig. 1).At a certain stage of running-in plug 8 of the workpiece 1 with a circular rotation of module 2 viscous liquid 4 begins to spread over the walls of the cavity 3 of the module 2. Liquid 6 of the cavity 5 under the action of gravitational forces causes it to move along the surface of the cavity 3 of module 2, which stimulates energy dynamically unstable position, module 2 on the plunger 7. Reaching the positions shown in Fig.2, the resonator 5 creates an additional overturning moment module 2-Mr, which translates module 2 in a state of dynamic instability. Under accelerated oscillation module 2 resonator 5 starts to make chaotic shock move against the walls of the cavity 3, and the liquid 6 inside the cavity 5, is transferred into the state hydraulic is directed waves of liquid, produced in this energy contributes to the translation of the resonator 5 in the state of elastic autoresonance. At this stage of the processing of the workpiece facing the active effects of the punch 8 and the reactive effects of the module 2 starts to perform regulated limited alternating turns in the direction same direction running her punch 8. In this case, module 2 on the workpiece impact shock pulses of variable (increasing) the intensity at the beginning of the process and constant intensity at the stage of elastic autoresonance module 2.Thus, in this way realized the effect hydroshock deformation autoresonance, allowing to greatly reduce the cost of energy input to ensure conditions developed plastic deformation, and influence of torsion fields generated by the rotation of the magnetic fluids 4 and 6 and the vortex energy field of the material of the resonator 5, the structural changes in the material of the workpiece at the micro level when implementing low-energy modes (mechanisms) rotational ductility. The way torsion svetodinamichesky materials processing, include the alternate application to it by the butt from obratnogo tool upsetting and effort working and idle running with the software in the workflow cycle redistribution component of the phase composition of the metal billet to the crystallographic level, characterized in that during idle running to the ends of the workpiece at the same time make the shock pulses of variable intensity with frequency increasing to the resonance, and autoresonant the impact of the shock pulse is maintained over time, indicated by the following expression

SUBSTANCE: present invention relates to a scope of metal forming, particularly, to method for manufacturing watertight, corrugated metal pipes. Longitudinal corrugations are formed on a strip of metal sheet by successive passages between counterposed corrugating barrels having alternated, circumferential ridges on their outer surfaces The opposite, longitudinal lips of the strip are bent in opposite directions. Then the strip of metal sheet is coiled into a helical shape, whereby the opposite, longitudinal lips overlap laterally. Before the opposite, longitudinal lips are crimped together between counterposed crimping rollers, a rubber gasket is fitted to one of the opposite longitudinal lips. Gasket has a bent profile capable of embracing the longitudinal lip at least partially. Whereby the material of the gasket, by effect of the crimping pressure, is reduced in thickness and deformed plastically at least in certain areas of the longitudinal lips which are biased against each other by the crimping action.
