Description

i veomsnße _ 2 _ Uppfinningen framgår närmare av följande beskrivning med bifogade rit- i ningar visande: 2Fig. l¿ en längdsektion av ett verktyg, såsom ett gängsvarvningsverktyg enligt uppfinningen, Fig. 2, en sektion längs linjen 2-2 i Fig. 1, och Fig. 5, en underläggspletta, ett skär och en ovanpå detta belägen spån- brytarplatta - i förstorad skala - försedda med urtagningar för transport av kylmedium. i veomsnße _ 2 _ The invention appears in more detail from the following description with the accompanying drawings showing: 2Fig. a longitudinal section of a tool, such as a thread turning tool according to the invention, Fig. 2, a section along the line 2-2 in Fig. 1, and Fig. 5, a washer plate, a cutting insert and a chip breaker plate located on top of it - in enlarged scale - provided with recesses for transporting refrigerant.

Det i Fig. 1-3 visade verktyget består av en borrstång 10 och en vid stången fästad inbyggnads- eller skärhållare ll försedd med en axiellt orienterad ställskruv 12. I skärhållaren ll är fästade ett skär 13, en underläggsplatta 14 och en ovanpå skäret 13 anbragt separat spånbrytarplat ta 15, vilka är fästade vid skärhållaren medelst en spännkropp 16 verkande mot spånbrytarplattan 15. Spännkroppen 16 är lösbart avbragt vid borr- stången medelst en_i spännkroppen upptagen låsskruv 17, som ingängas i borrstången. Verktyget är försett med kanaler för tillförsel av kylmedium, bestående av en urborrning 18 i stången samt en från denna urborrning le- dande smalare kanal l9 genom skärhållaren.ll ut till underläggsplattan lä.The tool shown in Figs. 1-3 consists of a drill rod 10 and a built-in or cutting holder 11 attached to the rod and provided with an axially oriented adjusting screw 12. A cutting insert 13, a washer plate 14 and a top plate 13 are attached to the cutting holder 11. separate chip breaker plate ta 15, which are attached to the cutting holder by means of a clamping body 16 acting against the chip breaker plate 15. The clamping body 16 is releasably mounted at the drill rod by means of a locking screw 17 received in the clamping body, which is inserted into the drill rod. The tool is provided with channels for supplying coolant, consisting of a bore 18 in the rod and a narrower channel 19 leading from this bore through the cutting holder 11 to the washer plate lä.

Utmärkande för verktyget enligt uppfinningen är ett.skäret lå ooh under- 'läggsplettan lä försetts med ett system av håligheter 20, 21 och 22 som bringar kylmediet i direkt kontakt med skärets 13 ovansida, dvs dess spån- sida. Samtidigt kan underläggsplattan 14 vara försedd med en eller flera från hålet 20 gående urtagningar 23, så att kylmediet, förutom genom kana- elerna 20, 21, 22 även ledes mot skärspetsen från skärets undersida, dvs Äfrånfsläppningsytan, Deni underläggsplnttan 14 utåtgående urtagningen 23 har företrädesvis utåt avsmalnande tvärsektion.Characteristic of the tool according to the invention is that the insert lay and the base plate 1 is provided with a system of cavities 20, 21 and 22 which bring the coolant into direct contact with the upper side of the insert 13, i.e. its chip side. At the same time, the washer plate 14 may be provided with one or more recesses 23 extending from the hole 20, so that the coolant, in addition to through the channels 20, 21, 22, is also directed towards the cutting tip from the underside of the insert, ie the discharge surface outwardly tapering cross section.

Såsom närmare visas i Fig. 5 är underläggsplattan 14 försedd med ett ge- nomgående, centralt beläget hål 20, som via kànalen 19 står i förbindelse med kanalen 18 genom skärhållaren. Från hålet 20 utgår ett antal grenkana- ler 25 riktade mot skärspetsen hos det skär 15, som är placerat ovanpå underläggsplatten 14. I likhet med underläggsplattan uppvisar även skäret -13 ett genomgående, centralt beläget hål 22, som ligger axiellt i linje med underläggsplattans hål 20. Från hålet 21 utgår likaså ett antal gren- kanaler 22 riktade mot skärspetsen hos skäret 13, vilka kan varan _ 5 _ 7901060-9 insintrade direkt 1 ett ytparti på skärets övre spànsida, eller i spån- brytarplattans 15 undersida. Båda hàligheterna 20 och 21 är lämpligen centralt upptagna i skäret och underläggsplattan och samtidigt oriente- rade vinkelrätt mot deras upplagsytor.As shown in more detail in Fig. 5, the washer plate 14 is provided with a through-going, centrally located hole 20, which via the channel 19 communicates with the channel 18 through the cutting holder. From the hole 20 a number of branch channels 25 face towards the cutting tip of the insert 15, which is placed on top of the washer plate 14. Like the washer plate, the insert -13 also has a through, centrally located hole 22, which is axially aligned with the holes of the washer plate. 20. From the hole 21 also emanate a number of branch channels 22 directed towards the cutting tip of the insert 13, which can the product sintered directly into a surface portion on the upper chip side of the insert, or in the underside of the chip breaker plate 15. Both cavities 20 and 21 are suitably centrally received in the insert and the backing plate and at the same time oriented perpendicular to their bearing surfaces.

Genom lämplig utformning av de 1 underläggsplattan gjorda urtagningarna 23, företrädesvis med utåt avsmalnande tvärsektion, såsom visats i Fig. 3, och samtidig applicering av kylmediet även från skärets spánsida via kanalerna 22 åstadkommas en effektiv och allsidig kylning av skärspetsen, vilket i väsentlig grad visat sig kunna förhöja livslängden hos skär av- sedda för utskärning av gängprofiler.By suitable design of the recesses 23 made in the washer plate, preferably with an outwardly tapered cross section, as shown in Fig. 3, and simultaneous application of the coolant also from the chip side of the insert via the channels 22, an efficient and versatile cooling of the cutting tip is achieved. be able to increase the service life of inserts intended for cutting thread profiles.
