Description
Anordning til fastspenning av arbeidsstykker, særlig bjelker.
FRANZ LITZKA,
Foreliggende oppfinnelse angår anordning til fastspening av arbeidsstykker, og særlig en anordning hvor en eller flere I-bj eiker kan fastspennes for skjærebrenning for tilforming av gitterbj eiker, f. eks. etter patent nr. 102.718, og stabilisering etter en slik deling.
Ved skjærebrenning av slike I-bj eiker
for fremstilling av gitterbj eiker deles disse i steget langsetter med en sagtannformet delelinje, hvoretter de to fremkomne halv-deler rykkes fra hverandre og forskyves en halv deling, slik at de fremkomne tenners toppunkter blir liggende overfor hverandre slik at det fremkommer en gitterbj elke når de to deler her sveises sammen, eventuelt etter innføring av formstykker slik det er beskrevet 1 patent nr. 102.718.
Anordningen i henhold til oppfinnelsen omfatter holdere, f. eks. hjelpebjelker, med hvilke begge flenser på den dobbelte T-bjelke som skal deles er forbundet på en slik måte at bjelkehalvdelene etter delingen fastholdes av holderne og beveges sammen med disse for å forskyve bjelkehalvdelene. Ved anordning av flere ved siden av hverandre liggende I-bj eiker som skal deles i en arbeidsgang, kan det mellom hver av disse bjelker som holder være anordnet en med to flenser forsynt hjelpebjelke.
Etter oppfinnelsen er det fordelaktig
som holdere å anordne i lengderetningen forstillbare klemorganer, særlig hydrauliske eller pneumatiske, stasjonære sylindere, med hvilke klemelementer, til be-
festigelse av flensene på I-bjelkene, et med en flens forsynt stempel er forbundet. Som klemorganer kan imidlertid også brukes mekaniske innretninger, f. eks. spindler.
Særlig er det hensiktsmesig å anordne et flertall klemorganer, spesielt hydraulisk eller pneumatisk påvirkede sylindere, fordelt langs den I-bj elke som skal deles, hvor hvert sylinderstempel meddeles forskjellig slaglengde for å frembringe bøyde bjelkehalvdeler. Ved individuell styring av de enkelte sylindere kan det frembringes en mangfoldighet av bjelkeformer. Videre er det fordelaktig å anordne sylindrene mellom to innbyrdes parallelle I-bj eiker og forsynt med to i motsatt retning virkende stempler.
Oppfinnelsen skal nedenfor forklares
nærmere med tegningen, hvor
fig. 1 viser et tverrsnitt gjennom et flertall I-bj eiker med fastspenningsanord-ninger. Fig. 2 og 3 er grunnriss av bjelker i rett og bøyet tilstand innspent 1 anordningen i henhold til oppfinnelsen. Fig. 1—3 viser på hvilken måte de enkelte I-bj eiker holdes fast og etter delingen blir stabilisert. Det er her likegyldig
om bjeikene er anordnet stasjonære eller
om de er anbragt på et kjørbart under-stell. Som det fremgår av fig. 1 kan det spennes fast et vilkårlig antall I-bj eiker parallelt ved siden av hverandre og ved anvendelse av like mange delapparater kan alle bjelkene 1 deles i en arbeidsgang. Hver enkelt av bjelkene 1 fastspennes enten ved
hjelp av en hjelpebjelke 60 eller spenn-innretninger 62, hvis lengde kan for-andres, slik at de enkelte bjelkehalvdeler etter delingen ikke kan vippe eller forskyve seg. Straks delingen av bjelkene er ferdig kan den fremste bjelkehalvdel ved hjelp av den dermed forbundne hjelpebjelke 60 i lengderetningen forskyves en halv deling t, hvorpå det i den samme innretning på skjøtesddene 2a, 2b foretas en punktsveising (hefting), hvorved de enkelte bjelkehalvdeler la, lb i det minste under transporten blir urokkelig forbundet med hverandre. Derpå blir disse sammen-heftede bjelkehalvdeler transportert videre for å sveises ferdige, for at den følgende I-bjelke kan deles. Ved utførelsen etter fig. 1 blir således de enkelte bjelkehalvdeler ikke på noe tidspunkt overlatt til seg selv.
Fig. 1 viser videre at det som spenn-innretninger kan brukes enten hydrauliske eller pneumatiske sylindere 62, hvis stempel er forsynt med flenser 63, på hvilke hjelpebjeikene eller korte formstykker 64 er festet. På disse z-formede formstykker 64 spennes I-tojeiken 1 fast ved hjelp av klemstykkene 65 og vriene 66.
Anvendelsen av spenninnretningene 62, 63 fremgår særlig av fig. 2 og 3 hvor de mellom rette hjelpebj eiker 60 beliggende avdelte bjelkehalvdeler A—F ved hjelp av spenninnretnlnger 62 tilformes slik at det kan fremstilles f. eks. bue-formede bjelker med liten overhøyde. Såvel klemstykkene eller -klørne 65 og 65' som flensene 63 har en sådan form at tildan-nelsen av bjelkehalvdelene ikke har noen innflytelse på den korrekte fastspenning av disse bjelkehalvdeler.
I fig. 2 er I-bjelkene vist i delt tilsand slik at hver bjelkehalvdel henger i sine tilhørende spennsyllndere 62. Stemplene i sylinderen 62 beveger seg så hver sin tildelte, bestemte slaglengde, slik athjelke-halvdelene B, C og F først trekkes bort fra de fastholdte bjelkehalvdeler A, D og E et stykke svarende til delelinjens 2 tann-høyde, hvorpå alle bjelkehalvdeler bøyes som fig. 3 viser. En sammenligning mellom fig. 2 og 3 viser hvilket slag hver enkelt sylinder 62 må bevirke for en arbeidsgang, såvel å atskille som å bøye alle bjelkehalvdelene. Derpå blir spennorganene mellom bjelkehalvdelene B og C samt mellom bjelkehalvdelen F og hjelpebj eiken 60 sammen med sine forskyvbare underlag 87 forskutt sidevls en halv deling t, hvorpå skjøtkantene sveises sammen. Den ved bøyningen frembragte overhøyde er sterkt overdrevet på tegningen. I virkeligheten er denne overhøyde så liten at feil i delingen t på grunn av bøyningen neppe er merkbar.
Etter at bjelkehalvdelene er heftet sammen med punktsveising kan de ved hjelp av en kran transporteres videre for å sveises ferdig. Det er også mulig å utføre spennsylindrene 62 løft- og senkbare så de dermed forbundne, buef ormede bjelker kan føres bort på rullebaner. Når sylinderen 62 under dette senkes ned under rullebanen, vil bueformen ikke være noen hindring.
