摘要： An annular workpiece 6 is rolled between two oppositely disposed forming rolls 2, 4, and two oppositely disposed growth rolls 22 and 24 acting at right angles to the line of action of the forming rolls. The forming rolls 2, 4, are brought together to roll form the workpiece 6 to a wall thickness dependent upon its weight, and the advance of the growth control rolls 22, 24 is controlled to a position which is also dependent upon the weight of the workpiece 6.

摘要： A method of roll forming an annular workpiece to a desired shape from a workpiece having dimensions within a tolerance range, in which the difference in weight between the workpiece and a nominally sized workpiece is determined and the workpiece is then roll formed to its desired shape by being squeezed between at least two rotating forming members which advance relatively towards one another to a fully advanced position to impress the desired shape into the workpiece followed by maintaining the forming members at their fully advanced position to complete the roll forming for a period of time known as the dwell time. The extent of advancement of the forming members or the dwell time is varied from the standard required for the nominally sized workpiece in dependence upon the difference in weight of the workpiece from the nominally sized workpiece so as to produce a final rolled workpiece whose diameter is substantially identical with that of a nominally sized workpiece subjected to the standard extent of advancement of the forming members or dwell time.

摘要： A method of rolling an initially annular workpiece between forming rolls in which after the forming rolls have been fully advanced they are retracted initially slowly for a predetermined distance. The forming rolls can then be further retracted at a greater speed. The slow retraction reduces the out of roundness of the finished rolled ring.
