Definitions
- the invention relates to a method for deburring metal parts by means of a High-pressure liquid jet with a pressure> 400 bar, which comes from a high-pressure nozzle emerges and is aimed at the workpiece to be treated, and an apparatus for performing the method on a metalworking machine.
- Such a method and such a device is known from DE 195 33 579 A1 known.
- the high pressure liquid jet with a high pressure up to 500 bar using an oil emulsion educated contain a maximum of 10 to 15% oil in Water and additives preferably emulsifiers, which have the finest distribution of the Favor oil in the water with which oil does not mix. Doing so achieves the deburring effect of the specifically heavier water and Usually, the maximum for the systems on the market 350 bar worked.
- This high pressure is mainly enough for water existing high-pressure liquid jet to ensure adequate deburring and to achieve cleaning effect.
- the deburring and cleaning process can, as this prior art shows, easily in the Integrate the manufacturing process of the workpiece when it is in the machine chamber is carried out and for the high pressure liquid jet already used for cooling the workpiece to be machined or cutting oil emulsion is used.
- the object of the invention is a deburring device of the type mentioned at the beginning Art to improve so that even oils as a high pressure liquid jet used with a sufficiently large deburring and cleaning effect without danger can be.
- this object is achieved by a method in which that uses a high pressure liquid jet with an oil content> 50% and that the high pressure nozzle with the workpiece to be machined during processing in a machine chamber of a metalworking machine arranged encapsulated workpiece chamber housed become.
- the encapsulated housing of the high pressure nozzle and the workpiece to be machined in an encapsulated workpiece chamber causes that when deburring Oil mist no longer represents a risk of fire and explosion, since that Volume of the workpiece chamber kept small and from the machine chamber be clearly decoupled with the door to be opened and closed and can not interfere with processes that take place there can. The oil mist cannot get into the machine chamber from this leak and lead to contamination.
- An apparatus for performing the process on a metal cutting machine Metalworking machine that has at least one machine chamber with one Has high pressure nozzle, the high pressure liquid jet on the in the Machine chamber introduced, workpiece to be treated is directed, and a high-pressure generating device for the high-pressure liquid jet with a pressure> 400 bar and a container for the processing liquid has, is characterized in that in the machine chamber Metal processing machine housed an encapsulated workpiece chamber is inserted into the high pressure nozzle and the workpiece to be treated can be inserted during processing.
- the workpiece chamber has a Provide connection for a line coming from the gas supply.
- the oil from the metal processing machine's oil tank is direct or over an intermediate oil tank of the high pressure generating device is supplied.
- high-pressure nozzles fed by the high-pressure generating device are arranged, their processing direction and distance to Workpiece are adjustable.
- Several high-pressure nozzles can be used on one single workpiece or it can be any workpiece from several Workpieces can each be assigned one or more high-pressure nozzles.
- the configuration can also be designed so that the high pressure generating device as a separate unit from the metalworking machine is trained.
- the medium with an oil content of> 50% is contained in an oil tank, from which it can be fed to a high-pressure generating device HD-Q is, as Fig. 1 shows.
- the medium is in the high pressure generating device HD-Q brought to a high pressure> 400 bar, in a known manner Pumps, pneumatic control devices and the like are used.
- the Medium is then fed to a high-pressure nozzle HD-D, which is encapsulated in a Workpiece chamber WK arranged and on the point to be deburred workpiece WS introduced into the workpiece chamber WK.
- the high-pressure liquid jet HD-FS emerging from the high-pressure nozzle HD-D is very energetic and breaks off or burrs on the workpiece.
- the medium that accumulates in the workpiece chamber WK flows through a Drain AL back to the oil tank ⁇ V.
- connection AS for a line coming from a corresponding gas supply GV. Is this additional security measure is not required, then the connection AS can also be closed.
- Fig. 2 now shows how the new deburring process in the manufacturing process the workpiece on a commercially available metal processing machine (turning and rotary probes with oil cooling and / or oil lubrication) can be integrated can.
- the oil of the metalworking machine MBM is also used as a medium used for deburring. It becomes from the oil tank ⁇ T of the metalworking machine MBM removed and directly or via an oil tank ⁇ V the High-pressure generating device HD-Q fed and to a high pressure Brought> 400 bar.
- the metalworking machine MBM has several processing stations into which the workpiece is brought one after the other. there Each processing station has special tools for it Processing operations assigned.
- Oil from the oil tank ⁇ T for cooling and / or lubricating the workpiece WS and / or the tools can be used.
- the oil is with the Chips removed, the chips removed and the oil tank ⁇ T again fed.
- deburring is carried out.
- This processing station has an encapsulated one Workpiece chamber WK, into which the WA held and finished workpiece WS is introduced.
- the high pressure nozzle HD-D is arranged and towards the deburring point of the workpiece WS aligned. Doing the alignment and the distance of the high-pressure nozzle HD-D to the workpiece is changed and can be set.
- WK also several high-pressure nozzles HD-D arranged and on one and the same Workpiece WS or be aligned to several workpieces.
- the outlet AL of the workpiece chamber WK leads to an indicated machine side Collection spout ALm and finally to the oil tank ⁇ T back.
- the workpiece chamber WK can be connected to a gas supply via the connection AS GV for carbon dioxide CO2 or nitrogen N.
