Telescopic cover with damping elements
Telescopic cover with scissor mechanism
This gully is an extruded aluminum profile which is screwed onto the rear walls of the cover.
The cover plate is bent downwards so that it projects into the gully. This allows the coolant between the plates to flow into the moulded gully.
Condensation water that forms under the cover plates is wiped off by a lip and drained into gullies to the front and back. This makes it possible to achieve a very high level of waterproofing.
This gully is screwed onto the rear wall. This has the advantage of, among other things, meaning that galvanized metal plates can be used (no welding necessary).
Telescopic covers can also be designed as a tandem system for very large travel lengths. This thereby enables the outer dimensions to be reduced to a minimum compared to the guideways.
The highest possible leak tightness is often the main requirement for a telescopic cover to be used when machine has hydrostatic guides. These requirements are complied with by integrating bellows. The bellows can be installed between the individual compartments or continuously under the telescopic cover.
Blind telescopic covers consist of smooth cover sheets which are guided in so-called tie down teeth and therefore do not require a direct connection to the guideway. Blind telescopic covers are usually used as rear wall covers within tooling machines. The tie down teeth can be made of various materials.
