Definitions
- the invention relates to a device which is suitable for automatically changing the tools, which can be heated by an external medium (for example electrical energy), for tempering milled profile surfaces on workpieces made of wood and wood-based materials into a device suitable for this purpose.
- an external medium for example electrical energy
- thermo-mechanical surface finishing of workpieces made of wood and wood-based materials cutting-less rotationally symmetrical tools are used immediately after machining.
- the tools are heated with basically known mechanisms of action (friction, vibration, electrical energy, warm air).
- the main problem of an industrial application of the known developments is to magazine the heated tools from the processing station in a device before and after the tempering process and to change new (already) heated tools with different profile shapes into the processing station. Due to the high temperature of the heated tools, the functional reliability when clamping the heated tools in the device and the necessary accuracy of fit of the clamping elements can only be guaranteed to a limited extent.
- the object of the invention is to eliminate the disadvantages of the prior art.
- a device for changing heatable tools is to be specified, which makes it possible to use heatable tools with different profile shapes in short succession, and consequently to achieve a sustainable increase in the productivity of the methods for surface treatment of workpieces made of wood or wood-based materials.
- a device which consists of a machine-fixed receptacle and an adapter which thermally insulates the heatable tool from the receptacle.
- the adapter is fixed and locked in a conical interface of the receptacle; there are also detachable connections for energy transfer for the heating medium.
- the heat transfer at the conical interface is significantly minimized by the use of poorly heat-conducting materials for the shaft of the adapter, it being preferably provided that the interface be functionally separated from the heatable profile tool by a heat-insulating layer.
- high-alloy steel and technical ceramics are used as heat-insulating materials for the shaft; Hard tissue is preferably used as the separating material. It is thus achieved that the temperature on the surface of the profile tool can be comparatively high, whereas the machine-fixed receptacle has much lower temperatures and consequently only minimal thermal expansions occur. This is the fit of the adapter and consequently that ensures safe industrial application of known smoothing processes.
- additional cooling media can be dispensed with.
- Detachable plug connections are also provided in the device according to the invention, which allow the supply of the heating medium to be interrupted during an automated tool change.
- the signal lines can be connected to the process-inherent control and evaluation unit via the plug connections, so that the exchange process is not impaired.
- the proposed device achieves the object of the invention by the almost complete thermal separation of the heatable profile tool from the clamping device of the tool.
- the device offers a Simple and safe way to automatically disconnect and connect the energy supply for the heating medium during the change process. This is achieved by decoupling the heating medium from the conical interface.
- the overall result is that the longstanding requirements with regard to high variability and safety in industrial use of the heatable tools are met.
- the adapter 1 shows the machine-fixed receptacle 1 and the adapter 1 3, which is clamped therein in a geometrically reproducible manner via the conical interface 2.
- the adapter 1 3 (and thus the heatable cutting-less profile tool 7) is centered by the draw-in cone of the interface 2, the mating surface of which has an inclination of 90 °; Otherwise, according to the invention, the angle of inclination is in the range from 50 °... 1 10 °.
- the profile tool 7 is fastened to the shaft 6 of the adapter 1 3 by means of a union nut 8.
- the profile tool 7 is heated by a heating cartridge 9, to which the electrical energy is supplied via the plug connections 1 0.
- the heat transfer from the tool 7 to the receptacle 1 is permanently minimized for the shaft 6 within the adapter 1 3 by the heat-insulating disc-shaped layer 5 made of hard tissue and by the use of poorly heat-conducting material, namely high-alloy steel.
- the adapter 1 3 for the heatable tool 7 is therefore drawn into the receptacle 1 by means of the conical interface 2 and locked by a tensioning slide with a conical clamping surface and a pull bolt 1 2.
- the release of the tool 7 is supported by an ejection device with a plunger 4.
- a contactless temperature sensor 11 is attached to the receptacle 1 as intended.
