Description

Drivverktøy for bruk sammen med et gjenget, metallisk festeelement.
Foreliggende oppfinnelse angår et
drivverktøy for inndrivning av et gjenget
festeelement, hvor verktøyet er av den type
som omfatter et skjær med en midtre kjerne og et antall vinkelmessig jevnt adskilte
vinger som rager radialt ut fra kjernen.
Slike drivverktøy er beregnet for bruk
ved inndrivning av metalliske, gjengede
festeelementer av den art som i sin øvre
ende har en fordypning for opptagelse av
et drivverktøy hvor fordypningen har et
midtre hulrom og et antall spor i omkrets-veggen for det midtre hulrom, idet sporene
er omkretsmessig jevnt adskilt og hvor
hvert spor har et par sidevegger og er innrettet til, mellom sideveggene, å oppta et
radialt fremstikkende, tilsvarende utformet parti på et drivverktøy som er opptatt
i fordypningen, idet det er fire slike spor
som strekker seg radialt utad i forhold til
det midtre hulrom slik at fordypningen har
omtrent korsform.
En form for festeelementer av den
ovenfor nevnte type er beskrevet i patent
nr. 107 765.
Som nærmere beskrevet i det nevnte
patent er det, for at fordelene ved festeelementet og spesielt fordelene ved drivfor-dypningen skal kunne oppnås i full ut-strekning, av spesiell betydning at driv-verktøyet for inndrivning av et slikt festeelement har en slik form at det på beste
måte kan komme til inngrep med den driv-verktøy-opptagende fordypning i festeelementet.
Ut fra de foranstående betraktninger
er det at foreliggende oppfinnelse omfatter et drivverktøy for inndrivning av et gjenget festeelement, og av den type som omfatter et skjær med en midtre kjerne og et antall vinkelmessig jevnt adskilte vinger som rager radialt ut fra kjernen, og hvor sideflatene på vingene er stort sett paral-lelle med verktøyaksen. Det særegne ved dette drivverktøy er at kjernen mellom hver av vingene er utformet med en utad-ragende V-formet ribbe, hvis tverrsnitt av-tar i retning mot spissen på skjæret for drivverktøyet.
Det skal nå henvises til vedføyde tegning hvor en utførelsesform for oppfinnel-sen er vist. Fig. 1 er et planriss av et drivverktøy for bruk sammen med et festeelement, sett aksialt i forhold til verktøyet i retning fra utenfor verktøyskjæret. Fig. 2 er et sideriss av skjærenden for
det drivverktøy som er vist i fig. 1.
Fig. 3 er et planriss av et festeelement utformet med en utsparing innrettet til å oppta det drivverktøy som er vist i fig. 1 og 2.
I fig. 1 og 2 er det vist et drivverktøy 48 for bruk med den fordypning som er vist
i fig. 6 i patent nr. 107 765 og i fig. 3 på ved-føyde tegning. Dette verktøy 48 omfatter skjær 49 med en kjerne 50 for fire vinger 51 som ligger i samme vinkelavstand fra
hverandre og som stråler ut fra kjernen og som hver er innrettet til å komme i inngrep med et av fordypningssporene 23. Skjæret 49 er også på omkretsen av kjer-
nen 50 mellom hver av vingene 51 utformet med ribber 52 med stort sett V-form, men med et utad avtagende tverrsnitt idet hver av dem er innrettet til å komme i inngrep med en av forsenkningene 24. Den ytre kant av hver ribbe 52 skråner således i retning mot skjæret 49 og i forhold til aksen for verktøyet, idet skråningsvinkelen er lik skråningsvinkelen for skjæringslinjen mellom sideveggene i forsenkningene 24, slik det er beskrevet i patent nr. 107 765. Denne vinkel er mellom 8 og 15° og den utadret-tede kant på hver ribbe 52 danner således en vinkel i det samme område, nemlig 8— 15°, med verktøyaksen.
Anordningen av disse ribber 52 som er gjort mulig ved tilstedeværelsen av de nevnte forsenkninger, tjener til å styrke drivskjæret 49 nær det sted hvor vingene 51 og kjernen 50 møtes, ved å øke tverr-snittet for kjernen 50 for disse steder, et trekk som er av spesiell betydning hvis skjæret skal overføre det høye dreiemoment som effektivt kan oppnås med fordypningen i festeelementet i henhold til patent nr. 107 765.
Skjæret 49 er som vel kjent ved frem-stilling av drivverktøy valset eller på annen måte bearbeidet til en form som er forut bestemt av den bestemte form av den stanse som skal danne fordypningen, slik at vingene 51 har samme form som stanse-vingene 39 beskrevet i ovennevnte norske patent.
Sideveggene eller sideflatene på verk-tøyvingene er således omtrent loddrette slik som beskrevet ovenfor og ligger med samme skråhet til et radialt plan gjennom aksen D—D for drivverktøyet som skråhe-ten for de tilsvarende sporsidevegger 25, 26 i forhold til elementaksen, nemlig 20' og 2° i det eksempel som er beskrevet. Drivverk-tøyribbene 52 har også samme form som stanseribbene 40. Både vingene 51 og ribbene 52 har en omkretstykkelse henhv. en radial tykkelse som under bearbeidelsen med hensikt er gjort litt mindre enn de tilsvarende dimensjoner på stanse vingene 39 og stanseribbene 40, slik at når verktøy-et er i fullt inngrep med festeelement-fordypningen, vil det før utøvelsen av dreiemomentet på verktøyet være en bestemt klaring mellom vingene 51 og sporene 23 og mellom ribbene 51 og forsenkningene 24.
Før utøvelsen av dreiemomentet på verktøyet vil denne klaring spesielt foreligge mellom hver av sideflatene på vingene 51 og de tilsvarende sidevegger 25, 26 i sporene 23 og vil også foreligge mellom sideflatene på ribbene 52 og veggene 28, 2"9 i forsenkningene 24, og denne klaring ligger i området 0,025 til 0,075 mm idet den største klaring foreligger ved de større størrelser, dvs. større festeelementdiame-tre og tilsvarende større fordypningsdia-metre.
Slike klaringsverdier som er nevnt, svarer til en forskjell i bredde mellom hver vinge 51 og spor 23 i området fra 0,05 til 0,15 mm og en forskjell mellom kjernedia-meteren for skjæret målt tvers over ribbene 52 og en fordypningsdiameter målt tvers over forsenkningene 24 i området fra 0,05 til 0,15 mm. I hvert tilfelle gjelder den minste breddeforskjell festeelementer og fordypninger med liten størrelse og den største breddedifferanse festeelementer og fordypninger med større størrelse.
For så vidt som stansefordypningen har nøyaktig samme form som stansen i det minste langs sideveggene for de radiale spor 23 og for de spor som utgjøres av forsenkningene 24 over hele dybden av disse spor og forsenknings-sidevegger slik som beskrevet ovenfor er det klart at forutsatt at driv-verktøyet er nøyaktig tilformet, slik det kan gjøres uten vanskelighet, oppnås den nevnte bestemte klaring mellom verktøyskjæret og den tilsvarende eller øn-skede fordypning.
Slik klaring er alt for liten til å (bevirke kasting av verktøyet og de derav følgende ulemper deriblant avsporing av drivverk-tøyet, og verktøyet holdes i bestemt aksialt rettet forhold til festeelementaksen. Sam-tidig er denne beregnede klaring, selv om den er liten, tilstrekkelig til å tillate at drivverktøyet med hånden lett kan stikkes inn i og trekkes ut fra festeelementfordyp-ningen, noe som er av spesiell betydning ved innsetting av festeelementer ved mon-teringsbånd e. 1. Slik beregnet klaring opp-tas så snart dreiemomentet for inndriving eller utskruing utøves på verktøyet, slik at når dreiemomentet først er utøvet blir sideflatene på vingene 51" straks bragt i stil-ling for overføring av dreiemomentet eller trykk til den tilsvarende sidevegg i hvert radialt fordypningsspor 23.
Med de klaringsverdier som er nevnt ovenfor, vil det når dreiemomentet økes, bli en liten avbøyning av metallet i feste-elementhodet og av det metall som utgjør vingene 51 slik at det også blir mulig å overføre noe dreiemoment mellom sideflatene på ribbene 52 og en eller annen av de to sidevegger i hver forsenkning, alt et-ter den retning verktøyet dreies, slik at noe ekstra dreiemoment kan overføres også til festeelementet langs forsenkningene.
