Definitions
- the invention relates to a method for deburring metal parts by means of a high-pressure liquid jet which emerges from a high-pressure nozzle and is directed onto the workpieces to be treated, and to an apparatus for carrying out the method on a metalworking machine.
- the high-pressure liquid jet is formed with a high pressure up to 500 bar using an olemulsion.
- oil emulsions contain a maximum of 10 to 15% oil in water and additives, preferably emulsifiers, which promote the finest distribution of the oil in the water with which the oil does not mix.
- the deburring effect is achieved by the specifically heavier water and is usually used in the systems on the market worked with a maximum of 350 bar.
- This high pressure is sufficient for the high pressure liquid jet, which mainly consists of water, in order to achieve a sufficient deburring and cleaning effect.
- the deburring and cleaning process can, as this prior art shows, easily in the manufacturing process integrate the workpiece if this is carried out in the machine chamber and the drilling or cutting oil emulsion already used for cooling the workpiece to be machined is used for the high-pressure liquid jet.
- the method according to the invention is characterized in that a high-pressure liquid jet with an oil content> 50% and a high pressure> 400 bar is used and that the high-pressure nozzle with the workpiece to be machined are accommodated in an encapsulated workpiece chamber during machining.
- the high pressure> 400 bar the specific light oil achieves a sufficient deburring and cleaning effect.
- the encapsulated housing of the high-pressure nozzle and the workpiece to be treated in an encapsulated workpiece chamber means that the oil mist formed during deburring no longer poses a fire and explosion hazard, since the volume of the workpiece chamber is kept small and from the machine chamber with the door to be opened and closed can be clearly decoupled and processes that take place there do not interfere with each other The oil mist cannot get into the machine chamber, emerge from it and lead to contamination.
- the safety of the system is increased further by supplying the workpiece chamber with carbon dioxide or nitrogen during the treatment of the workpiece via a gas supply
- a device for performing the method on a metal-cutting machine with at least one processing station in the machine chamber and a high-pressure nozzle directed towards the workpiece to be treated and fed with the high-pressure liquid jet is characterized in that the medium for the high-pressure liquid jet from an oil tank removed from the metalworking machine, brought to a high pressure> 400 bar via a high-pressure generating device and fed to the high-pressure nozzle accommodated with the workpiece in an encapsulated workpiece chamber, the workpiece chamber being arranged in the machine chamber
- the oil from the oil tank of the metalworking machine is supplied to the high-pressure generating device directly or via an intermediate oil tank
- a plurality of high-pressure nozzles fed by the high-pressure generating device are arranged in the workpiece chamber, the machining direction and distance of which from the workpiece can be adjusted.
- Several high-pressure nozzles can be directed at a single workpiece or one or more high-pressure nozzles can be assigned to each workpiece from several workpieces.
- the configuration can also be designed such that the high-pressure generating device is designed as a separate unit from the metalworking machine.
- Fig. 1 is a block diagram for explaining the new method
- FIG. 2 shows a block diagram with a method integrated in a commercially available metalworking machine.
- the medium with an oil content of> 50% is contained in an oil tank ⁇ V, from which it can be fed to a high-pressure generating device HD-Q, as shown in FIG. 1.
- the medium is brought to a high pressure> 400 bar in the high-pressure generating device HD-Q, pumps, pneumatic control devices and the like being used in a known manner.
- the medium is then fed to a high-pressure nozzle HD-D, which is arranged in an encapsulated workpiece chamber WK and is directed at the point to be deburred of the 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 energy-intensive and breaks off the burrs on the workpiece or removes them.
- the medium that accumulates in the workpiece chamber WK flows back to the oil tank ⁇ V via an outlet AL.
- the workpiece chamber WK has a connection AS for a line coming from a corresponding gas supply GV. If this additional safety measure is not required, the AS connection can also be closed.
- Fig. 2 shows how the new deburring process can be integrated into the manufacturing process of the workpiece on a commercially available metalworking machine (rotary and rotary probes with oil cooling and / or oil lubrication).
- the oil from the metalworking machine MBM is also used as a medium for deburring. It is removed from the oil tank ⁇ T of the metalworking machine MBM and fed directly or via an oil tank ⁇ V to the high-pressure generating device HD-Q and to a high pressure
- the metalworking machine MBM has several processing stations into which the workpiece is brought one after the other. Each processing station is assigned special tools for the processing operations to be carried out therein.
- oil from the oil tank ⁇ T can be used for the machining operations for cooling and / or lubricating the workpiece WS and / or the tools. The oil is transported away with the chips, the chips are removed and the oil tank is returned to the ⁇ T. Deburring is carried out in the last processing station in the cycle of the production process.
- This machining station has an encapsulated workpiece chamber WK into which the workpiece WS held and finished in a workpiece holder WA is inserted.
- the high-pressure nozzle HD-D is arranged in the workpiece chamber WK and aligned with the part of the workpiece WS to be deburred.
- the orientation and the distance of the high-pressure nozzle HD-D from the workpiece can be changed and adjusted.
- several high-pressure nozzles HD-D can also be arranged in the workpiece chamber WK and aligned with one and the same workpiece WS or with several workpieces.
- the outlet AL of the workpiece chamber WK leads to an indicated, machine-side collecting outlet ALm and finally back to the oil tank ⁇ T.
- the workpiece chamber WK can be connected via the connection AS to a gas supply GV for carbon dioxide C02 or nitrogen N.
