Description

_10 15 20 25 30 40 8205165-7 _ i genom att slipstationen innefattar slipmoduler som tillsammans *genom överlappning täcker ytan för ett förbímatat ämne, som häri- genom i mån av behov kan bearbetas fläckvis eller över hela ytan kontinuerligt, varvid slipmodulerna har nästan mot respektive. bearbetningsytor vinkelräta spindelaxlar för slipskivorna. In that the grinding station comprises grinding modules which together * by overlap cover the surface of a pre-fed substance, which can thereby, if necessary, be processed in spots or over the entire surface continuously, the grinding modules having almost against respective. machining surfaces perpendicular to spindle shafts for grinding wheels.

För att säkerställa att överhettning inte sker av slipskivorna är det lämpligt att kyla dessa, antingen med luft eller med vatten eller med en kombination härav. Vid fläckslipning av ytan är det Y lämpligt att styra varje slipmodul individuellt från en föregående z sprick-.eller feldetektering av ämnets yta.To ensure that the grinding wheels do not overheat, it is advisable to cool them, either with air or with water or with a combination thereof. When spot grinding the surface, it is convenient to control each grinding module individually from a previous z crack or error detection of the surface of the blank.

Uppfinningen skall nedan beskrivas närmare i form av ett ut- föringsexempel i anslutning till ritningen. Härvid visar §ig_l en slipanordning i enlighet med uppfinningen šedd från sidan och fig Z samma anordning eller maskin sedd i strängens tvärled.The invention will be described in more detail below in the form of an exemplary embodiment in connection with the drawing. In this case, Fig. 1 shows a grinding device in accordance with the invention seen from the side and Fig. Z the same device or machine seen in the transverse direction of the string.

Den på ritningarna visade slipmaskinen är placerad i direkt anslutning till stränggjutningsmaskinens riktrullar 8 mellan vilka ämnet 2 passerar. Slípmaskinen innefattar ett maskinstativ 7, i vilket ett antal slipmoduler 3 är anordnade. Varje slipmodul innefattar en av en motor 6 via en splinesförsedd axel S driven nästan vertikal spindel 3 och på varje spindel sitter en slip- skiva I. Genom splinesförbandet mellan motor och spindel 3 kan denna förflyttas i riktning från och mot ämnet 2. Denna vertikala rörelse för slipskiva och spindel regleras av en hydraulcylinder 9, som är fäst i ett slipstativ 4 resp via ett öra (en konsol) är fäst vid slipspindeln. Varje slipstativ 4 för en slipmodul är justerbart inhängt i maskinstativet för justering av slip- skivans angreppsvinkel relativt ämnet. Genom denna inhängning av slipmodulerna blir det även möjligt att relativt snabbt och enkelt byta ut dessa vid reparation och service.The grinding machine shown in the drawings is placed in direct connection with the guide rollers 8 of the continuous casting machine between which the blank 2 passes. The grinding machine comprises a machine frame 7, in which a number of grinding modules 3 are arranged. Each grinding module comprises an almost vertical spindle 3 driven by a motor 6 via a spindled shaft S and on each spindle is a grinding wheel I. Through the spline connection between motor and spindle 3 this can be moved in the direction from and towards the blank 2. This vertical movement for grinding wheel and spindle is controlled by a hydraulic cylinder 9, which is attached to a grinding stand 4 or via an ear (a bracket) is attached to the grinding spindle. Each grinding stand 4 for a grinding module is adjustably suspended in the machine frame for adjusting the angle of attack of the grinding wheel relative to the blank. Through this suspension of the grinding modules, it also becomes possible to replace them relatively quickly and easily during repair and service.

Som synes av fig I och Z innefattar den beskrivna slipmaskinen fyra övre och fyra undre slipmoduler, vilka är så förskjutna i sid- .led att deras slipomrñden överlappar varandra och täcker hela ämnets bredd. Naturligtvis kan maskinen lämpligen även innefatta en kantslipníng av ämnet, men denna har utelämnats i förtydligande syfte.As can be seen from Figures 1 and 2, the grinding machine described comprises four upper and four lower grinding modules, which are so displaced laterally that their grinding areas overlap each other and cover the entire width of the blank. Of course, the machine may suitably also comprise an edge grinding of the blank, but this has been omitted for clarification purposes.

Kylvatten för kylning av slipskivorna inmatas via en vinkel I0 till kanaler i spindelaxeln, som förgrenas ut i skivfläns och slipskiva. Största mängden av det förbrukade kylvattnet kommer att förângas vid kontakten med det varma ämnet. Det icke förângade spíllvattnet uppsamlas via skyddsplåtar i en spillvatten- 15 behållare under maskinen. Skyddsplntarna utgör samtidigt spräng- skydd för slipskivorna. Slipmaskínen är lämpligen försedd med detekteríngsorgan för att säkerställa, att den icke arbetar då ämne icke finns i maskinen. Spillvattenuppsamligen kan på icke närmare visat sätt kompletteras med en pumpanordning och sedi- menteringsanordníngar. Vidare är maskinen naturligtvis försedd med utsugningsaggregat för hanteringen av slipstoft och vatten- ånga, men även detta har utelämnats i förtydligande Maskinen är slipmotorns kontrollera kraftenrmot ligen styrs syfte. i normalfallet försedd med en anordning som mäter effekt och använder det uppmätta värdet för att trycket i hydraulcylindern 9 och därmed anpassníngs- ämnet, så att motoreffekten hålls konstant. Lämp- slipskívans ansättning mot ämnesytan av systemet för slipskivans effektreglering. Härigenom erhålles en mjuk slip- kontakt och hållning av inkoppling till effektreglerad slipning för konstant- slipdjup. i 8205165-7Cooling water for cooling the grinding wheels is fed via an angle I0 to channels in the spindle shaft, which branch out into the disc flange and grinding wheel. The largest amount of the cooling water consumed will evaporate on contact with the hot substance. The non-evaporated waste water is collected via protective plates in a waste water container under the machine. The protective plants also provide explosion protection for the grinding wheels. The grinding machine is suitably provided with detection means to ensure that it does not work when no substance is present in the machine. Wastewater collection can be supplemented in a manner not shown in more detail with a pumping device and sedimentation devices. Furthermore, the machine is of course equipped with extraction units for the handling of abrasive dust and water vapor, but even this has been omitted in clarification. normally provided with a device that measures power and uses the measured value to the pressure in the hydraulic cylinder 9 and thus the fitting material, so that the engine power is kept constant. Applying the grinding wheel to the blank surface of the grinding wheel power control system. This results in a soft grinding contact and holding of connection to power-regulated grinding for constant grinding depth. and 8205165-7
