Description

Den foreliggende oppfinnelse vedrører en anordning for perforering av drensrør av plast som er korrugert i skruelinjeform, omfattende en ramme med et styre- og støtteorgan for plastrøret, en innretning for fremstilling av perforeringene samt et drivorgan for perforeringsinnretningen. The present invention relates to a device for perforating drainage pipes made of plastic that is corrugated in helical form, comprising a frame with a control and support member for the plastic pipe, a device for producing the perforations and a drive member for the perforation device.

Det er kjent slike fremgangsmåter for fremstilling av inn-snitt eller huller i plastrør hvor det anvendes spesielle sage-redskaper. Such methods are known for producing incisions or holes in plastic pipes where special sawing tools are used.

Denne type dreneringsrør fremstilt ved hjelp av de nevnte redskaper kan bare fremstilles med stor vanskelighet ved hjelp av slike kompliserte redskaper, og derfor med temmelig høye frem-stillingsomkostninger. Åpningene i de fremstilte huller vil lett kunne tilstoppes som følge av de ru kanter som frembringes ved sageoperasjonen. This type of drainage pipe produced using the aforementioned tools can only be produced with great difficulty using such complicated tools, and therefore with rather high production costs. The openings in the produced holes will be easily blocked as a result of the rough edges produced by the sawing operation.

Det er også kjent å fremstille huller i plastrør ved å stikke varme nåler gjennom rørveggen, men som følge av den tid som medgår for å passere gjennom rørveggen, kan ikke" denne frem-gangsmåte gjennomføres ved kontinuerlig fremstilling. It is also known to produce holes in plastic pipes by inserting hot needles through the pipe wall, but due to the time required to pass through the pipe wall, this method cannot be carried out in continuous production.

Videre vil huller fremstilt ved hjelp av en varm nål all-tid oppvise kragepartier dannet av smeltet plast under påvirk-ning av den varme nål. Furthermore, holes made with the help of a hot needle will always show collar parts formed by melted plastic under the influence of the hot needle.

Det har også vært foreslått å fremstille huller i korrugerte rør ved å utforme vulster i dalene på de korrugerte rør og å skjære av toppartiet av vulstene, slik at de nevnte huller dannes. Derved vil den ytre flate på veggen rundt åpningen nød-vendigvis bli oppruet, noe som vil medføre lett tilstopping av hullene. Videre vil hullene omsluttes av materiale med en tykk-else som er forskjellig fra den øvrige veggtykkelse, slik at det kan forekomme at det tynne materiallag rundt hullet blir bøyet. It has also been proposed to produce holes in corrugated pipes by forming beads in the valleys of the corrugated pipes and cutting off the top part of the beads, so that the said holes are formed. Thereby, the outer surface of the wall around the opening will necessarily be roughened, which will lead to easy clogging of the holes. Furthermore, the holes will be surrounded by material with a thickness that is different from the other wall thickness, so that it may occur that the thin layer of material around the hole is bent.

Formålet med oppfinnelsen er å komme frem til et apparat The purpose of the invention is to arrive at an apparatus

for kontinuerlig fremstilling av huller av ønskete dimensjoner for continuous production of holes of desired dimensions

i et korrugert rør, særlig i fordypningene i plastrøret, uten å anvende komplisert utstyr og uten at de fremstilte huller i røret skal ha tendens til å gjenstoppes for derved å oppnå lang leve-.tid for røret, samt uten at det dannes kragepartier rundt hullene i veggen. in a corrugated pipe, especially in the depressions in the plastic pipe, without using complicated equipment and without the holes produced in the pipe having a tendency to get plugged again in order to thereby achieve a long life for the pipe, and without the formation of collar parts around the holes in the wall.

Dette er muliggjort ved at rørstyreorganet består av en hul, dreibar mutter med skruelinjeformet innerflate, at perforeringsinnretningen, som er i form av en lokkedel som stanser ut hull i rørveggen, ved hjelp av en anordning er bevegelig stort sett radialt i forhold til røret enten i åpninger i rørstyreorganet eller aksialt like utenfor dette, og at den nedre ende av lokkedelen i uvirksom stilling befinner seg utenfor rørets ytre generatrise. This is made possible by the fact that the pipe guide consists of a hollow, rotatable nut with a helical inner surface, that the perforation device, which is in the form of a lid part that punches holes in the pipe wall, is movable largely radially in relation to the pipe either in openings in the pipe guide or axially just outside this, and that the lower end of the lure part in the inactive position is outside the pipe's outer generatrix.

Ifølge en utførelsesform av anordningen er perforeringsinnretningen bevegelig radialt i mutteren ved hjelp av en betjeningskam som er plassert på en stasjonær krans og som påvirker et hode på perforeringsinnretningen. Når perforeringsinnretningen av hodet skyves til kortvarig inngrep med røret og danner et hull i dette, vil den fjære i en spalte i mutteren og ikke hindres av veggene i denne spalte. According to one embodiment of the device, the perforating device is movable radially in the nut by means of an operating cam which is placed on a stationary ring and which affects a head of the perforating device. When the perforating device of the head is pushed into brief engagement with the pipe and forms a hole therein, it will spring into a slot in the nut and not be obstructed by the walls of this slot.

Ifølge en særlig foretrukket utførelsesform av anordningen er mutteren utstyrt med en skive med et ringformet spor med en innbuktning som samvirker med et fremspring på perforeringsinnretningen og som styrer dennes radielle bevegelse. According to a particularly preferred embodiment of the device, the nut is equipped with a disk with an annular groove with an indentation which cooperates with a projection on the perforation device and which controls its radial movement.

Ved å anvende rørformet styre- og støtteorganer kan stiv-heten for røret som skal behandles økes i det understøttete område og like ved dette område. Med uttrykket "like ved" menes for eksempel høyden 5 cm eller generelt en avstand hvor det kan observeres en øket stivhet. Det blir derved mulig å fremstille huller under stanse- eller lokkeoperasjonen, uten å anvende en kjerne på rørets innerside, noe som medfører vesentlige fordeler. By using tubular control and support members, the stiffness of the pipe to be treated can be increased in the supported area and close to this area. The expression "close to" means, for example, the height of 5 cm or, in general, a distance where an increased stiffness can be observed. It thereby becomes possible to produce holes during the punching or luring operation, without using a core on the inside of the tube, which entails significant advantages.

Oppfinnelsen skal nå forklares under henvisning til de med-følgende tegninger, hvori: Fig. 1 viser et snitt gjennom en anordning ifølge oppfinnelsen . The invention will now be explained with reference to the accompanying drawings, in which: Fig. 1 shows a section through a device according to the invention.

Fig. 2 viser et snitt langs linjen II-II i fig. 1. Fig. 2 shows a section along the line II-II in fig. 1.

Fig. 3 viser en modifisert utførelse av anordningen ifølge oppfinnelsen. Fig. 4 viser et snitt langs linjen IV-IV i fig. 3. Gjengitt på fig. 1 og 2 er en anordning som består av en innfatning 1 som holder en stillestående krans 2, hvori et kule-lager 3 brukes til å sikre en dreibar mutter 4 som tjener som styreelement og som støtteelement for et forholdsvis tynt plast-rør (for eksempel 0,2 - 0,6 mm tykt). Mutterens 4 innervegg er profilert samsvarende med profilen på et rør 6 som skal bearbeides. Fast festet på den dreibare mutter 4 er et element i form av en lokkedor 8 utstyrt med skjærekanter 7 og hode 9. Betjeningskammer 10 for å drive lokkedoren 8 er anbrakt på den stillestående krans 2. Fig. 3 shows a modified version of the device according to the invention. Fig. 4 shows a section along the line IV-IV in fig. 3. Reproduced in fig. 1 and 2 is a device consisting of a frame 1 which holds a stationary ring 2, in which a ball bearing 3 is used to secure a rotatable nut 4 which serves as a control element and as a support element for a relatively thin plastic pipe (for example 0.2 - 0.6 mm thick). The inner wall of the nut 4 is profiled to match the profile of a pipe 6 to be processed. Fixed on the rotatable nut 4 is an element in the form of a decoy mandrel 8 equipped with cutting edges 7 and head 9. Operating chamber 10 for driving the decoy mandrel 8 is placed on the stationary ring 2.

Anordningen funksjonerer på følgende måte: Et rør fremstilt av en rørformingsmaskin styres inn i den profilerte del 5 av den dreibare mutter 4. Denne drives med fordel av rørformingsmaskinen ved hjelp av tannhjul. På den måten blir prosessen synkronisert. Mutteren 4 med lokkedor 8, hode 9 og skjærekanter 7 roterer inn-til hodet treffer en betjeningskam 10, hvorpå lokkedoren trykkes ned gjennom en kanal i mutteren 4, og et hull frembringes i rør-veggen. Det er klart at antallet huller som kan lages i rør-veggen er avhengig av antallet betjeningskammer 10. The device functions in the following way: A pipe produced by a pipe forming machine is guided into the profiled part 5 by the rotatable nut 4. This is driven with the advantage of the pipe forming machine by means of gears. In this way, the process is synchronized. The nut 4 with decoy mandrel 8, head 9 and cutting edges 7 rotates until the head hits an operating cam 10, whereupon the decoy mandrel is pressed down through a channel in the nut 4, and a hole is produced in the pipe wall. It is clear that the number of holes that can be made in the pipe wall depends on the number of operating chambers 10.

Borene er fordelaktig plassert på en slik måte at de frem-bringer huller.utelukkende i det korrugerte rørs fordypninger. The drills are advantageously placed in such a way that they create holes exclusively in the depressions of the corrugated pipe.

Doren er fjærstyrt (11) for å sikre at den føres tilbake. Det er bemerkelsesverdig at huller kan lages uten at en hylse The mandrel is spring controlled (11) to ensure that it is guided back. It is noteworthy that holes can be made without a sleeve

til understøtte på rørets innside anvendes. for support on the inside of the pipe is used.

I fig. 3 og 4 gjengis en annen foretrukket utførelse, hvori også finnes en innfatning 1 og en dreibar mutter 4 som tjener som styre- og støtteorgan for røret. Mutterens innervegg (4 og 5) er også profilert i samsvar med røret som skal bearbeides. Denne mutter fører en skive med et ikke-sirkelformet spor 12. I dette spor kan et fremspring 14 forbundet med en stasjonær lokkedor bevege seg. Når mutteren roterer, følger skiven med, og frem-springet som er forbundet med lokkedoren vil følgelig bli ført av sporet 12. På grunn av sporets ikke-sirkulære form, blir doren trykket ned når den treffer den ikke-sirkulære del, og rørveggen blir gjennomlokket. Som man kan se av tegningen, ligger mutteren 4 i betraktelig avstand fra skjærekantenes arbeidsfelt. In fig. 3 and 4 show another preferred embodiment, in which there is also a frame 1 and a rotatable nut 4 which serves as a guide and support member for the pipe. The inner wall of the nut (4 and 5) is also profiled in accordance with the pipe to be processed. This nut guides a disk with a non-circular groove 12. In this groove, a projection 14 connected to a stationary mandrel can move. As the nut rotates, the disc follows, and the protrusion connected to the decoy mandrel will consequently be guided by the slot 12. Due to the non-circular shape of the slot, the mandrel is pressed down when it hits the non-circular part, and the pipe wall becomes covered. As can be seen from the drawing, the nut 4 is at a considerable distance from the working field of the cutting edges.
