Abstract: A method for automatic calculation of a pass schedule in the radial forging of steel tubes in a radial forging machine is disclosed. The forging machine includes at least four forging tools arranged around the circumference of the workpiece, which are set up and adapted for synchronous forging operation over at least a partial length of the workpiece and/or the tube. Starting parameters for the forging process, preferably radial forging process, are entered into a pass plan calculation program and target parameters for the radial forging process are defined. The pass plan calculation program calculates a pass plan or a forging sequence on the basis of these start and target parameters.

Abstract: Radial forging of long products made of metal workpieces in a radial forging machine uses at least four forging tools arranged around the circumference of the workpiece, which are set up and adapted to simultaneously carry out the forging operation. An automatic pass schedule calculation includes entering start parameters for the radial forging process into a pass schedule calculation program and defining target parameters for the radial forging process. The pass schedule calculation program calculates a pass schedule or a forging sequence based on these start and target parameters. The pass schedule calculation program determines a temperature variation and the temperature distribution over the cross section of the long product and takes into account the change in shape during radial forging.

Abstract: A method for automatic pass schedule calculation during forging, in particular radial forging, of stepped shafts made of metal workpieces, in particular steel, in a forging machine, preferably a radial forging machine with at least four forging tools arranged around the circumference of the workpiece, which are set up and adapted for simultaneous forging the workpiece and/or the stepped shaft, includes: entering starting parameters for the forging process, preferably radial forging process, into a pass schedule calculation program; specifying target parameters for the forging process, preferably radial forging process; and calculating, by the pass schedule calculation program, based on these start and target parameters, a pass plan or calculated a forge sequence. A control and/or regulation unit and a forging machine for carrying out the method are disclosed.
