Description
. Den foreliggende oppfinnelse vedrører en blåsestøpt spunstønne av den i dansk ansøkning nr. 2225/78 omhandlede art. Denne kjente tønne er forsynt med i tverrsnitt. L-formede rulleprofiler som ved tønnens ender forløper i omkretsretningen langs tønnemantelen og er utformet i ett med denne, og hvor L-profilenes loddrette gren peker oppad ved tønnens øvre.ende og nedad ved tønnens nedre ende under dannelse av spor for mottagelse av gripe- og transportverktøy. . The present invention relates to a blow-molded sheet barrel of the kind referred to in Danish application no. 2225/78. This well-known barrel is provided with in cross-section. L-shaped roller profiles which, at the ends of the barrel, extend in the circumferential direction along the barrel mantle and are designed as one with this, and where the vertical branch of the L-profiles points upwards at the upper end of the barrel and downwards at the lower end of the barrel, forming grooves for receiving gripping and transport tools.
Denne utforming av rulleprofilene har en spesiell betydning. Gripeverktøyet for oppheising og transport av tønnen er som regel forsynt med gripearmer som er innrettet til å ligge an under den vannrette utad forløpende rulleprofilgren og bak den loddrette oppad pekende profilgren. Tønnens samlede vekt overføres til nedre gripearm mens den This design of the roller profiles has a special meaning. The gripping tool for lifting and transporting the barrel is usually provided with gripping arms which are arranged to rest under the horizontal outwardly extending roller profile branch and behind the vertical upward pointing profile branch. The barrel's overall weight is transferred to the lower gripper arm while it
bak den loddrette gren inngripende gripearm,sikrer tønnen mot en bortglidning. Som følge herav skal det<:>øvre rulleprofils loddrette gren' peke oppad mens det nedre rulleprofils loddrette gren skal peke nedad. behind the vertical branch engaging gripping arm, secures the barrel against slipping away. As a result of this, the<:>vertical branch of the upper roller profile' must point upwards, while the vertical branch of the lower roller profile must point downwards.
Som bekjent består formen for fremstilling av slike tønner av to formhalvdeler som er sammensatt i et langsgående formdeleplan. Oventil og nedentil er de to formhalvdeler As is well known, the mold for producing such barrels consists of two mold halves which are assembled in a longitudinal mold plane. Above and below are the two mold halves
igjen inndelt i vannrette plan under dannelse av skyveorganer. again divided into horizontal planes during the formation of thrusters.
Når den fleksible slange senkes ned fra blåsestøpe-apparatets støpehode, er de to formhalvdeler forskjøvet bort fra hverandre i retning mot venstre og høyre, slik at den bøyelige slange kan føres inn i den åpne blåseform. Med hen-blikk på dette er skyveorganene åpne oventil og nedentil. When the flexible hose is lowered from the casting head of the blow molding apparatus, the two mold halves are shifted away from each other in the direction to the left and right, so that the flexible hose can be fed into the open blow mold. With this in mind, the pushers are open above and below.
Når den fleksible slange er bragt på plass ved nedsenking i formen, lukkes de to formhalvdeler og blåseoperasjonen innledes. Den gjennom blåsedorene innstrømmende luft utvider den flek sible slange som bringes i anlegg mot den lukkede forms inner-side og antar herved tønnens på forhånd fastlagte form. Det. øvre og nedre skyveorgan er åpne, slik at materialet kan trenge inn i de åpne øvre og nedre formlommer og derved danne de innad åpne flensringer. When the flexible hose has been brought into place by immersion in the mold, the two mold halves are closed and the blowing operation begins. The air flowing in through the blowers expands the flexible hose which is brought into contact with the inner side of the closed form and thereby assumes the pre-determined shape of the barrel. The. upper and lower pushing means are open, so that the material can penetrate into the open upper and lower mold pockets and thereby form the internally open flanged rings.
Deretter lukkes skyveorganene. I formdelen er det tilveiebragt profilringer tilsvarende rulleprofilets form, hvori det fra tønnemantelen avgitte materiale innføres. De på denne måte formede rulleprofiler er L-formede i tverrsnitt og forsynt med en vannrett og en loddrett oppad pekende henholdsvis nedad pekende gren. The pushers are then closed. In the form part, profile rings corresponding to the shape of the roll profile are provided, into which the material discharged from the barrel jacket is introduced. The roller profiles shaped in this way are L-shaped in cross-section and provided with a horizontal and a vertical branch pointing upwards and downwards respectively.
Som følge av den forskjellige materialfordeling i tønnemantelen oppstår det vanskeligheter ved utformingen av . rulleprofilene. I klemsømområdet er den ekstruderte slanges materiale ved lukket form fordoblet. Under blåseoperasjonen rettes slangen ut, dvs. det fra klemsømmen vandrende slange-<p>mråde får en stadig mindre veggtykkelse i hurtig tempo. As a result of the different material distribution in the barrel jacket, difficulties arise in the design of the . the rolling profiles. In the pinch seam area, the material of the extruded hose is doubled when closed. During the blowing operation, the hose is straightened, i.e. the hose <p>m area traveling from the clamp seam gets an increasingly smaller wall thickness at a rapid pace.
Ved utformingen av rulleprofilene i det øvre og.nedre skyveorgan er det forskjellige materialvolumer til rådighet, hvorved skyveverktøyene som følge av den større material-mengde i klemsømområdet ikke kan lukke helt til, slik at den tilfredsstillende rulleprofilutforming ved de tynne områder er utelukket. Som følge av anvendelsen av gripeverktøy er en pålitelig rulleprofilutforming en forutsetning. When designing the roller profiles in the upper and lower push member, there are different volumes of material available, whereby the push tools, as a result of the larger amount of material in the pinch seam area, cannot close completely, so that the satisfactory roller profile design in the thin areas is excluded. As a result of the use of gripping tools, a reliable rolling profile design is a prerequisite.
Det har vært forsøkt å la fremstillingsverktøyet haAttempts have been made to allow the manufacturing tool to have
en bølgekontur i tverrdeleplanet nedenunder skyveorganene, hvorved bølgedalene er anbragt i områder med stor materialopphopning mens bølgetoppene er anbragt i områder med for-holdsvis liten materialopphopning. Ved dette kjente verktøy er det riktignok mulig å tilveiebringe en fullstendig avluk-king av skyveorganene uten at det største materialvolum presses inn i tønnens indre, samtidig med at det oppnås en overalt konstant høyde av rulleprofilets loddrette gren. a wave contour in the cross-sectional plane below the pushers, whereby the wave valleys are located in areas with a large accumulation of material, while the wave crests are located in areas with a relatively small accumulation of material. With this known tool, it is admittedly possible to provide a complete shut-off of the pushers without the largest volume of material being pressed into the interior of the barrel, while at the same time achieving a everywhere constant height of the vertical branch of the roller profile.
Herved avtar den vannrette rulleprofilgrens veggtykkelse fra formskilleområdet frem mot en tønneperiferivinkel på 90°, kontinuerlig inntil en til tønnemanteltykkelsen svarende veggtykkelse, hvoretter profilgrenens veggtykkelse atter vokser kontinuerlig frem mot det rteste formdeleplans område. Formålet med oppfinnelsen er å tilveiebringe en annen løsning for fremstilling av spunstønner, hvor de på tønne-mantelen påstøpte rulleprofiler med L-formet tverrsnitt under hensyntagen til den ujevne materialfordeling under den inn-ledende formoperasjon bibringes et ensartet inngrepsspor. Hereby, the wall thickness of the horizontal roller profile branch decreases from the mold separation area towards a barrel peripheral angle of 90°, continuously until a wall thickness corresponding to the barrel jacket thickness, after which the wall thickness of the profile branch increases continuously again towards the area of the closest mold separation plane. The purpose of the invention is to provide another solution for the production of sheet piles, where the rolled profiles with an L-shaped cross-section cast onto the barrel shell, taking into account the uneven material distribution during the initial molding operation, are provided with a uniform engagement groove.
Dette formål oppnås ifølge,oppfinnelsen ved en spuns-tønne av den innledningsvis nevnte art og er-karakterisertved at ved rulleprofiler med konstant profilhøyde og ensartet veggtykkelse i den vannrette profilgren, avtar den loddrette profilgrens veggtykkelse svarende til materialtilførselen ved en overalt konstant spordybde ved rulleprofilene kontinuerlig fra formdeléplanet frem til en tønneperiferivinkel på 90°, hvoretter spordybden atter vokser kontinuerlig frem til formdeleplanet ved periferivinkelen på l80°. This purpose is achieved, according to the invention, by a sheet pile barrel of the type mentioned at the outset and is characterized by the fact that in the case of roller profiles with a constant profile height and uniform wall thickness in the horizontal profile branch, the wall thickness of the vertical profile branch decreases corresponding to the material supply with a everywhere constant groove depth at the roller profiles continuously from the mold parting plane up to a barrel peripheral angle of 90°, after which the groove depth again grows continuously up to the mold parting plane at the peripheral angle of l80°.
Oppfinnelsen skal i det følgende forklares nærmere The invention will be explained in more detail below
under henvisning til tegningen, hvorwith reference to the drawing, where
fig. 1 viser en i samsvar med oppfinnelsen utformet spunstønne forsynt med rulleprofiler ved den øvre og den nedre ende, og fig. 1 shows a sheet barrel designed in accordance with the invention, provided with roller profiles at the upper and lower ends, and
fig. 2 samme sett ovenfra.fig. 2 same seen from above.
Tønnemantelen på den i fig. 1 viste spunstønne er betegnet méd henvisningstallet 3. På tønnemantelen 3 er rulleprofilene 1 og 2 fremstilt ved sammentrykning av de ikke viste formdeler i tønnens akseretning etter blåsestøp-ningen og i retning radielt utad. På de vannrett, utadrettede rulleringgrener 13 er de parallelt med.tønnens.akse i retning mot tønnens øvre ende 4 henholdsvis tønnens nedre ende 5 om-bøyde, loddrette grener 10 på rulleprofilene 1 og 2 anbragt. Tønnens øvre ende 4 og tønnens nedre ende 5 rager frem foran rulleprofilene 1 og 2, hvorved rulleprofilene ved stabling av et antall tønner ovenpå hverandre, er beskyttet samtidig med at de etterlater så meget plass at en håndtering ikke kan forhindres. Spunsene 6 og 7 er anbragt i fordypninger 8 i tønnens øvre ende 4. The barrel jacket on the one in fig. 1, the sawn barrel shown is denoted by the reference number 3. On the barrel jacket 3, the roll profiles 1 and 2 are produced by compression of the not shown mold parts in the barrel's axial direction after the blow molding and in the direction radially outwards. On the horizontal, outwardly directed roller ring branches 13, the bent vertical branches 10 on the roller profiles 1 and 2 are arranged parallel to the barrel's axis in the direction towards the barrel's upper end 4 and the barrel's lower end 5 respectively. The barrel's upper end 4 and the barrel's lower end 5 protrude in front of the roller profiles 1 and 2, whereby the roller profiles when stacking a number of barrels on top of each other are protected while leaving so much space that handling cannot be prevented. The sponges 6 and 7 are placed in recesses 8 in the upper end 4 of the barrel.
Under de overfor hverandre anbragte spunsområder fore-finnes de kraftigste materialoppsamlinger i formskillesømmene. Svarende til blåseformens utforming avtar veggtykkelsen til de loddrette rulleprofilgrener 10 kontinuerlig ved overalt konstant dybde av sporene 9, fra formdeleområdet frem til en tønneperiferivinkel på 90° i en til tønnemanteltykkelsen svarende veggtykkelse og økes derfra kontinuerlig frem til området ved den neste formskillesøm (fig. 2). Beneath the sheeting areas placed opposite each other, the heaviest accumulations of material are found in the form separation seams. Corresponding to the design of the blow mold, the wall thickness of the vertical roller profile branches 10 decreases continuously at everywhere constant depth of the grooves 9, from the mold parting area up to a barrel peripheral angle of 90° in a wall thickness corresponding to the barrel jacket thickness and is continuously increased from there up to the area at the next mold separation seam (fig. 2 ).
Som det ytterligere fremgår av fig. 2, er den vannrette rulleprofilgren 13 i området ved den største materialopp-samling ved siden av spunsene 6 og 7 gjort bredere ved inn i tønnens indre rettede innbuktninger 11. As further appears from fig. 2, the horizontal roller profile branch 13 in the area of the largest material collection next to the sheet piles 6 and 7 is made wider by indentations 11 directed into the barrel's interior.
Blåsestøpt spunstønne av termoplast, hvilken tønne er forsynt med i tverrsnitt L-formede rulleprofiler, som ved i tønnens ender forløper i omkretsretningen langs tønnemantelen og er utformet i ett med denne, og hvor L-profilenes loddrette gren peker oppad ved tønnens øvre ende og nedad ved tønnens nedre ende under dannelse av spor for mottagelse av gripe- og transportverktøy,karakterisert vedat ved rulleprofiler med konstant profilhøyde og ensartet veggtykkelse i den vannrette profilgren (13), avtar den loddrette profilgrens (10) veggtykkelse svarende til material-tilførselen ved en overalt konstant spordybde ved rulleprofilene (1,2), kontinuerlig fra formdeleplanet frem til en tønneperi-ferivinkel på 90°, hvoretter veggtykkelsen atter vokser kontinuerlig frem til formdeleplanet ved periferivinkelen på 180°. Blow molded sheet barrel made of thermoplastic, which barrel is provided with L-shaped roller profiles in cross-section, which at the ends of the barrel run in the circumferential direction along the barrel jacket and are designed as one with this, and where the vertical branch of the L-profiles points upwards at the upper end of the barrel and downwards at the lower end of the barrel during the formation of grooves for receiving gripping and transport tools, characterized in that in the case of rolling profiles with a constant profile height and uniform wall thickness in the horizontal profile branch (13), the wall thickness of the vertical profile branch (10) decreases corresponding to the material supply at a everywhere constant groove depth at the rolling profiles (1,2), continuously from the form parting plane up to a barrel peripheral angle of 90°, after which the wall thickness again grows continuously up to the form parting plane at the peripheral angle of 180°.
