| Description |
Cold Rolling Machine
The function of the machine lies in the technology of cold forming - rolling of
cylindrical, conical and transition radius surfaces of shaft components, e.g.
vehicle axles. Among other things, this function predetermines the area of
??application of the machine for specialized production of parts using surface
strengthening technology, always perpendicular to the surface of the rolling
tool to the material surface by means of the B-axis tilting mechanism
controlled by the CNC system. he locking of the rolling heads in a given
position is ensured by a drive with self-locking worm gearboxes.
The rolling equipment is located on a longitudinal support. The slide moves
along the machine bed in the longitudinal direction by means of a CNC-
controlled Z axis. The movement in the X-axis is realized hydraulically by two
quill of rolling heads placed against each other, into which the rolling tools
themselves are clamped. Continuous pressure changes on the rolling tools can be
changed in the program during the work cycle. The system enables indirect
independent measurement of rolling force, recording and archiving of rolling
process data.
