Description
78135333-7 gen utan att demontering behöver ske, varvid ett lämpligt verktyg kan stickas in genom öppningen och bringas i ingrepp med tandningen sä att en förskjutning i tätningspackningens sammanpressningsrikt- ning kan ske. 78135333-7 without the need for disassembly, using a suitable tool can be inserted through the opening and brought into engagement with the toothing so that a displacement in the compression direction of the sealing gasket ning can happen.
Med denna metod kompenseras vidare sättningar i en ny tätning (an- passning av tätningen). Slutligen blir det genom justeringsmöjlighe- ten möjligt att från början utnyttja en större tolerans på tätnings- packningar.With this method, settlements in a new seal are further compensated ( fitting of the seal). Finally, through adjustment options, possible to take advantage of a greater tolerance on sealing gaskets.
Uppfinningen är speciellt lämpad för vidareutveckling av den i krav -4 i svenska patentansökan nr. 7703696-0 beskrivna kolv-cylinder-en- heten med vars hjälp plastkomponenter med nötande egenskaper doseras.The invention is particularly suitable for further development of it in claims -4 in Swedish patent application no. 7703696-0 described piston-cylinder-one- with the aid of which plastic components with abrasive properties are dosed.
Nämnda patent har i princip samma målsättning som angivits ovan, näm- ligen att möjliggöra en noggrann och steglös dosering av nötande plastkomponenter i en nötningstålig och enkel anordning..Said patent has in principle the same objective as stated above, to enable an accurate and stepless dosing of abrasive plastic components in a wear-resistant and simple device ..
Enligt krav 2 möjliggörs en lätt inställning av skruvhylsan vid liten öppning. En liten öppning möjliggör även ett utförande enligt krav 3.According to claim 2, an easy adjustment of the screw sleeve at small is possible opening. A small opening also enables an embodiment according to claim 3.
Gängbromsen enligt krav 4 fixerar den önskade inställningen av skruv- hylsan och förhindrar att denna oavsiktligt förskjuts under drift.The thread brake according to claim 4 fixes the desired setting of the screw the sleeve and prevents it from being inadvertently displaced during operation.
Uppfinningen förklaras i det följande närmare med hjälp av ett på bi- fogade ritning visat utföringsexempel, där fig. 1 visar ett längdsnitt igenom en kolv-cylinder-enhet och fig. 2 visar uppifrån en detalj i fig. 1.The invention is explained in more detail below with the aid of a attached drawing shows exemplary embodiments, where Fig. 1 shows a longitudinal section through a piston-cylinder unit and Fig. 2 shows from above a detail in Fig. 1.
Kolv-cylinder-enheten uppvisar en cylinder 1 och en dubbelkolv 4.The piston-cylinder unit has a cylinder 1 and a double piston 4.
Cylindern 1 eller dubbelkolven 4 är funktionsmässigt upptill uppde- lad i en drivcylinder 2 respektive en drivkolv 5, och är vid undre änden uppdelad i en doseringscylinder 3 respektive en doseringskolv 6. Vid den undre änden är doseringscylindern 3 tillsluten med hjälp av en påskruvad.fläns 7, i vilken finns två hål 8 och 9, av vilka det ena (9) via en reglerbar pump 27 och en ledning 28 matar in plast- komponenter i en doseringskammare 16, och av vilka det andra (8) är avsett för bortförsel av plastkomponenter från doseringskammaren 6.The cylinder 1 or double piston 4 is functionally at the top of the load in a drive cylinder 2 and a drive piston 5, respectively, and is at the bottom the end divided into a dosing cylinder 3 and a dosing piston, respectively 6. At the lower end, the dosing cylinder 3 is closed with help of a screwed-in flange 7, in which there are two holes 8 and 9, of which one (9) via an adjustable pump 27 and a line 28 feeds plastic components of a dosing chamber 16, and of which the other (8) is intended for the removal of plastic components from the dosing chamber 6.
Vid övre änden av drivcylindern 2 finns påskruvat ett lock 11, som har ett hål 10 för tillförsel av tryckmedium, och som vidare har ett hål för en på dubbelkolven 4 anordnad reglerstång 12. Denna utgör en del av den kolvstång 13 som förbinder kolvarna 4 och 5 med varandra, och på vilken kolvarna 4 och 5 är monterade medelst gängförband. 7805333-7 Medan drivkolven 5 belastas av ett normalt tryckmedium och dess tät- ningspackning 14 därvid utsätts för en normal belastning, är dose- ringskolven 6 och dennas tätningspackning 15 utsatta för en avsevärd förslitning därigenom att det via hålet 9, medan en spärrventil 30 blockerar hålet 8, i doseringskammaren 16 transporteras in plastkom- ponenter som innehåller nötande material, och som därefter under in- verkan av drivkolven 5, medan hålet 9 blockeras med hjälp av en spärr- ventil 29, pressas ut via hålet 8.At the upper end of the drive cylinder 2 a lid 11 is screwed on, which has a hole 10 for supplying pressure medium, and which further has one hole for a control rod 12 arranged on the double piston 4. This constitutes a part of the piston rod 13 connecting the pistons 4 and 5 to each other, and on which the pistons 4 and 5 are mounted by means of threaded joints. 7805333-7 While the drive piston 5 is loaded with a normal pressure medium and its sealing packing 14 is then subjected to a normal load, the dosage the ring piston 6 and its sealing gasket 15 are subjected to a considerable wear by passing it through the hole 9, while a shut-off valve 30 blocks the hole 8, in the dosing chamber 16 is transported in plastic components containing abrasive materials, which are subsequently action of the drive piston 5, while the hole 9 is blocked by means of a locking valve 29, is pushed out via the hole 8.
Detta kompenseras enligt uppfinningen därigenom att en på doserings- kolven 6 förskruvbar, således i kolvens längdled förskjutbart anord- nad skruvhylsa 17, mellan sin undre ändyta och en kolvvulst 18 pres- sar ihop tätningspackningen 15, varigenom den reducerade tätnings- verkan åter förbättras. Detta sker utan demontering av kolv-cylinder- enheten därigenom att ett stångliknande verktyg föres in igenom en öppning 19 vid mitten på väggen till cylindern 1. Verktyget bringas i ingrepp med en tandning 21 på skruvhylsan 17, och med hjälp av det- ta verktyg roteras skruvhylsan 17 relativt doseringskolven 6. Därvid kommer den minskande kammaren 23 att avluftas via avluftningshål 24.This is compensated according to the invention in that a piston 6 is screwable, thus slidably arranged in the longitudinal direction of the piston. screw sleeve 17, between its lower end surface and a piston bead 18 is pressed. assembles the sealing gasket 15, whereby the reduced sealing effect is improved again. This is done without disassembly of the piston-cylinder the unit by inserting a rod-like tool through a opening 19 at the center of the wall of the cylinder 1. The tool is brought in engagement with a toothing 21 on the screw sleeve 17, and by means of the take tools, the screw sleeve 17 is rotated relative to the dosing piston 6. Thereby the decreasing chamber 23 will be vented via vent holes 24.
Om så är nödvändigt kan under denna justering av tätningspackningen 15 ett ytterligare, stångliknande verktyg föras in igenom en ovanför öppningen 19 anordnad andra öppning 20 och stickas in i en urborr- ning 22 eller i en av flera urborrningar 22, varigenom dubbelkolven 4 säkras mot rotation. Skruvhylsan 17 är med hjälp av en såsom gäng- broms fungerande, i ett ringspår 25 i det gängade partiet av skruv- hylsan 17 inlagd plastring 26 låst mot oavsiktlig rotation under drift. öppningarna 19 och 20 är i det visade exemplet cirkulära och kräver därför föga utrymme. Detta möjliggörs därigenom att justering av skruvhylsan 17 sker i det övre ändläget för dubbelkolven 4, dvs vid ett bestämt område på cylindern 1, samt därigenom att tandningen 21, såsom framgår av fig. 2, är anordnad runt periferin på skruvhyl- san 17.If necessary, during this adjustment of the sealing gasket can An additional, rod-like tool is inserted through one above the second opening 20 is arranged in the opening 19 and inserted into a bore 22 or in one of several bores 22, whereby the double piston 4 is secured against rotation. The screw sleeve 17 is by means of a threaded brake function, in an annular groove 25 in the threaded portion of the screw the sleeve 17 inserted plastic ring 26 locked against unintentional rotation during operation. the openings 19 and 20 in the example shown are circular and require therefore little space. This is made possible by the adjustment of the screw sleeve 17 takes place in the upper end position of the double piston 4, ie at a certain area on the cylinder 1, and thereby that the toothing 21, as shown in Fig. 2, is arranged around the periphery of the screw sleeve. san 17.
