Pressure rolling method and device for pressure rolling

摘要

The invention relates to a flospinning method according to which: a blank (12) is placed on a mandrel (16) of a flospinning machine; the blank is rotated in relation to at least one flospinning roller (18); the at least one flospinning roller (18) is radially and/or axially advanced with regard to the blank (12), and; the flospinning roller axially stretches the blank (12) by flospinning whereby forming a workpiece (14). The inventive method is characterized in that: at least one compensating area (26) is shaped inside the workpiece (14) in order to compensate for variations in dimensions of the blank (12); geometric data of the blank (12) or of the workpiece (14) is determined prior to and/or during flospinning by means of a measuring device (46, 48, 50, 52); in order to obtain desired final dimensions of the workpiece (14), the geometric parameters of the at least one compensating area (26) are individually calculated according to the determined geometric data, and; a control device serves to control the advance of the flospinning roller (18) according to the calculated geometric parameters of the compensating area (26) whereby obtaining a workpiece (14) with the desired final dimensions regardless of variations in dimensions of the blank (12). The invention also relates to a device for carrying out flospinning.
