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.

A method for radial forging a tube made of metal in a radial forging machine with at least four forging tools arranged around a circumference of the tube, the method comprising:
- entering start parameters for the radial forging process into a pass schedule calculation program;
- defining target parameters for the radial forging process;
- calculating a pass schedule based on the start parameters and target parameters by the pass schedule calculation program;
- and
- performing a forging operation on the tube by controlling the radial forging machine in accordance with the pass schedule.
A radial forging machine for the radial forging of a tube made of metal, comprising:
- at least four forging tools arranged around a circumference of the tube, which are set up and adapted to simultaneously carry out a forging operation over at least a partial length of the tube;
- and
- a control and/or regulation unit including a pass schedule calculation program, the control and/or regulation unit being configured for
- entering start parameters for the radial forging operation into the pass schedule calculation program,
- defining target parameters for the radial forging operation,
- calculating a pass schedule or a forging sequence based on the start parameters and target parameters by the pass schedule calculation program, and
- controlling the at least four forging tools and executing the pass schedule or the forging sequence.
