The forming and sizing sections incorporate a quick-change system with quick decoupling from the universal joint to the drive shaft of the horizontal roll assembly.
In the Turks Heads, a detachable cartridge design is used to enable quick changeover. The cross frame housing the rolls can be removed as a mono-block assembly.
A spare set of detachable cross frames with rolls can also be prepared offline in advance.
During changeover, the shaft assembly — including the rolls, shafts, and bearing blocks — is lifted out of the horizontal stand as a complete block.
A hydraulic cylinder is used to disengage the universal shaft, which simplifies the changeover process by reducing the need for manual disassembly on the stand.
While the offline roll change is being completed, another pre-assembled shaft assembly can be installed back onto the horizontal stand to complete the swap.
The detachable cartridge design allows the Turks Head cross frame to be removed as one integrated unit, rather than as separate components.
What is the main idea of the quick change system?
It allows the shaft assembly and Turks Head cartridge to be prepared in advance, so changeover can be completed by swapping pre-assembled units.
What happens during changeover?
The universal shaft is disengaged by a hydraulic cylinder, the complete shaft assembly is lifted out, and a prepared replacement assembly is installed in its place.
What is the detachable cartridge design?
It is the structure that allows the Turks Head cross frame to be removed as a single mono-block assembly.
Is a spare assembly available?
Yes. A spare set of detachable cross frames with rolls can be prepared offline in advance as a replacement unit.
