The article presents the results of development and research of the technological process of forming wide outer flanges of lids of malt and distillation columns on sheet blanks by rolling stamping. For this purpose, equipment has been developed in the form of a rolling device for a lathe and an autonomous rolling unit, which allow to form the outer flanges with a conical roll. The rolling unit to the lathe provides the presence of coil springs for pressing the roll to the workpiece with the mandrel. Both settings provide the ability to change the angle of the axis of the rolling unit relative to the axis of the mandrel with the workpiece.
Studies have shown that the technological capabilities of the process are limited by the corrugation of the flange wall. The power calculation of flanging of external flanges by a conical roll by the SHO method is carried out and formulas for determination of deformation forces are received. The acceptable accuracy of these formulas has been experimentally confirmed, and there is a tendency to increase the error with increasing geometric dimensions of the workpiece.
To assess and expand the technological capabilities of the process, an analysis of the formation and deformed state of the workpieces. Since the main danger in the formation of external flanges by the SHO method is the loss of stability in the form of corrugations, the paper obtained an expression for determining the maximum width of the flange under the condition of a stable process. If it is necessary to obtain more developed flanges, it is proposed in the second stage to provide thinning of their wall by drawing with the use, if necessary, heating the workpiece by induction method.
