Abstract

A bending machine for bending thin-walled tube profiles (16) such as spacer profiles or edge rails for sealed insulating glass units comprising two separate bending pins (22) situated opposite one another at mutually displaceably arranged lateral guides (18, 20). Profiles of different widths can hereby be bent. The bending pins (22) have a rivet-like shape with a head on a stem or neck, where the side edge of the profile is guided in the slot between the rear side of the head of the pin and the lateral guide during the bending process. By bending the side edges across the stems or the necks, which have a small bending radius compared with that of the head, the side edges appear in almost full height upon the bending, thus presenting a larger contact face for the glass than is otherwise the case. <IMAGE>

Description

DK 169909 B1DK 169909 B1

Den foreliggende opfindelse angår en bukkemaskine til bukning af tyndvæggede rørprofiler, navnlig afstandsprofiler eller kantskinner til isoleringsruder med et i det væsentlige rektangulært tværsnit, og hvor buk-5 ningen foregår over en bukkedorn.The present invention relates to a bending machine for bending thin-walled pipe profiles, in particular spacing profiles or edge rails to insulating panes having a substantially rectangular cross section, and the bending takes place over a bending mandrel.

I isoleringsruder samles glasset omkring tyndvæggede rørprofiler af aluminium eller stålblik. Tidligere skar man profilerne op i længder svarende til rudernes kantlængder og samlede profilstykkerne til en ramme med 10 hjørneelementer. Da hjørneelementerne er forholdsvis dyre og fremgangsmåden tidrøvende, samtidig med at den medfører et forholdsvist stort svind, har man længe forsøgt at bukke profilerne i stedet, og der findes da også i dag bukkemaskiner på markedet specielt beregnet 15 hertil. Et eksempel på en sådan bukkemaskine er omhandlet i EP-A2- 0 318 748. Bukket, der skal foretages, er overvejende et skarpt 90° buk, idet det altoverskyggende antal vinduer er firkantede med vinkelrette hjørner. Der kan ikke tillades bløde afrundede buk, og samtidig skal 20 bukket på indersiden, der vender ind i ruden, og som er synligt, have et æstetisk tiltalende udseende. Desuden er det et krav, at sidekanterne efter bukningen er plane og ligger i samme plan som sidekanterne udenfor det bukkede område. Da glasset klæbes til profilernes side-25 kanter er det ydermere et krav, at udstrækningen af sidekanterne i bukket er så stort som overhovedet muligt for at få lige så god vedhæftning med glasset som på de lige strækninger af profilet. Om der sker en deformation ved strækningen af profilets yderside, den side, der 30 vender ud fra ruden, kan dette tolereres. Denne ligger skjult efter rudens montering og er i øvrigt forseglet som hele rudens rundtgående kant.In insulating panes, the glass is gathered around thin-walled aluminum or steel sheet profiles. Previously, the profiles were cut into lengths corresponding to the edge lengths of the windows and the profile pieces were assembled into a frame with 10 corner elements. Since the corner elements are relatively expensive and the process time-consuming, while at the same time causing a relatively large shrinkage, the profiles have long been tried to bend the profiles, and today there are also bending machines on the market specially designed for this. An example of such a bending machine is disclosed in EP-A2- 0 318 748. The bending to be made is predominantly a sharp 90 ° bend, the overshadowing number of windows being square with perpendicular corners. Soft rounded abdomen cannot be allowed, and at the same time, the 20 abdomen on the inside that faces into the pane and which is visible must have an aesthetically pleasing appearance. In addition, it is a requirement that the side edges after the bend are flat and lie in the same plane as the side edges outside the bent area. Furthermore, as the glass is adhered to the side edges of the profiles, it is a requirement that the extent of the side edges of the bend is as large as possible to obtain as good adhesion to the glass as on the straight stretches of the profile. If a deformation occurs at the stretch of the exterior of the profile, the side facing out from the pane, this can be tolerated. This is hidden behind the pane's mounting and is otherwise sealed as the entire circumferential edge of the pane.

En helt. anden problemstilling ved bukkemaskinerne er, at de umiddelbart kun kan bukke afstandsprofiler med 35 samme tværsnitsdimension. Afstandsprofiler har i det væsentlige samme højde givet af vinduesfalsens dybde, DK 169909 B1 2 \ * hvorimod bredden varierer betydeligt afhængig af den forskrevne afstand mellem glasset og om det drejer sig om to eller tre lags ruder. De kendte bukkemaskiner kan ikke uden videre omstilles mellem de forskellige bredder 5 afstandsprofiler. Fra EP-A2- 0 241 174 kendes dog et enkeltstående eksempel på en bukkemaskine, der umiddelbart kan bukke afstandsprofiler af forskellig bredde.A hero. another problem with the bending machines is that they can only bend spacers with the same cross-sectional dimension immediately. Distance profiles have essentially the same height given by the depth of the window fold, whereas the width varies considerably depending on the prescribed distance between the glass and whether it is two or three layers of panes. The known bending machines cannot easily be switched between the different widths 5 distance profiles. However, from EP-A2-0241 174 a stand-alone example of a bending machine is known which can immediately bend spacers of different widths.

Maskinen omfatter to vridehoveder med en gennemgående cylindrisk bukkedorn i vridehovedernes centerlinie, og TO hvor det ene vridehoved kan forskydes sideværts i forhold til det andet via en trykluftcylinder. Maskinen har imidlertid samme ulempe som maskinen i henhold til EP-A2- 0 318 748, nemlig at profilet kollapser i hjørnet ved bukningen.The machine comprises two turning heads with a continuous cylindrical buckthorn in the center line of the turning heads, and TO where one turning head can be displaced laterally relative to the other via a compressed air cylinder. However, the machine has the same disadvantage as the machine according to EP-A2- 0 318 748, namely that the profile collapses in the corner at the bend.

15 Formålet med opfindelsen er at angive en bukkema skine, der opfylder ovennævnte krav til bukningens udførelse, og som uden omstilling kan bukke afstandsprofiler med forskellige bredder.The object of the invention is to provide a bending shine which meets the above-mentioned requirements for the execution of the bending and which without bending can bend spacer profiles of different widths.

Dette opnås med en bukkemaskine ifølge opfindelsen, 20 der er ejendommelig ved, at den omfatter to separate, overfor hinanden beliggende bukkedorne på sidestyr, og som rager ind over profilets overside, og hvor bukkedornenes yderside er udformet med et parti, der under bukkeprocessen indledningsvis deformerer profilets overside 25 lokalt ved siderne, og hvor bukkedornene yderligere er udformet således, at profilets sidevægge under den videre bukning kan rummes i en spalte ved bukkedornenes rod ved sidestyret til stabilisering af sidevæggene. Under bukningen styres profilets sidevægge op i spalterne ved 30 bukkedornenes rod ved sidestyrene og stabiliseres.This is achieved with a bending machine according to the invention, characterized in that it comprises two separate, facing lateral buckling mandrels, which project over the upper side of the profile, and the outer side of the buckthorns being formed with a portion which initially deforms during the bending process. the upper side of the profile 25 locally at the sides, and wherein the bending mandrels are further shaped such that the lateral profile of the profile can be accommodated in a slot at the root of the bend mandrels at the lateral guide to stabilize the side walls. During the bending, the side walls of the profile are guided up into the slots at the root of the bending mandrels at the side guides and stabilized.

Efter bukningen fremstår sidekanterne næsten i deres fulde højde, da bukkeradien i spalten er betydelig mindre end bukkeradien af bukkedornenes yderparti. Dermed fremkommer en større anlægsflade for glasset i bukket.After the bending, the lateral edges appear almost at their full height, since the bending radius in the slot is significantly smaller than the bending radius of the outer portion of the bending mandrels. This results in a larger contact surface for the glass in the bucket.

35 Bukkedornene udformes fortrinsvis med en naglelignende form med et hoved på en stilk eller hals, hvor hovedet * *- DK 169909 B1 3 udgør dornens yderparti, og spalten, der styrer profilets sidevæg under bukningen fremkommet ved stilken mellem sidestyret og den af hovedet ind mod sidestyret vendende flade. Sidekanterne bukkes da over stilkene.Preferably, the buckthorns are formed with a nail-like shape with a head on a stem or neck, the head * * - DK 169909 B1 3 constituting the outer portion of the mandrel, and the gap controlling the side wall of the profile during the bend provided by the stem between the lateral guide and the head towards sideways facing surface. The side edges are then bent over the stems.

5 Dornene kan naturligvis også være udformet i selve styrene og kun fremtræde med de for bukningen nødvendige flader.Of course, the mandrels can also be formed in the guides themselves and appear only with the surfaces required for the bending.

Ved at sidestyrene med bukkedorne er indbyrdes forskydelige, kan maskinen umiddelbart anvendes til 10 bukning af profiler med forskellige bredder. Det ene sidestyr er sædvanligvis fast i siden af profilernes fremføringsbane i maskinen, og det andet kan forskydes i forhold dertil.Because the side guides with the buckle mandrels are mutually displaceable, the machine can be used immediately for 10 buckling profiles of different widths. One side guide is usually fixed to the side of the profile feed path in the machine, and the other can be displaced relative thereto.

Opfindelsen skal i det følgende beskrives nærmere 15 under henvisning til medfølgende tegning, hvorpå fig. 1 viser en bukkemaskine ifølge opfindelsen set fra den ene side, fig. 2 viser bukkemaskinen set direkte fra den ene ende, 20 fig. 3 viser et forstørret tværsnit i maskinen ved bukkedornene, fig. 4 viser et forstørret billede fra siden ved bukkedornene, fig. 5 viser en bukkedorn i forstørret målestok, og 25 fig. 6 viser rent principielt bukning af et af standsprofil.The invention will now be described in more detail with reference to the accompanying drawing, in which: FIG. 1 is a side view of a bending machine according to the invention; FIG. 2 shows the bending machine seen directly from one end; FIG. 3 shows an enlarged cross-section of the machine at the buckthorns; FIG. 4 shows an enlarged side view of the buckthorns; FIG. 5 shows an enlarged scale buckthorn, and FIG. 6 shows in principle a bending of one of the stand profile.

Bukkemaskinen består rent principielt af et stel 2 med en pladeformet overdel 4, der støtter den bukkede del af profilet under bukkeprocessen. Maskinen har auto-30 matisk fremføring for profilerne, der ellers er computerstyret for automatisk bukning af profilerne. Bukkenes placering fastlægges ud fra en tæller 8 i profilernes fremføringsbane. Henvisningstallene 10, 12 angiver henholdsvis et bukkehoved og en bukkeaktuator, mens 14 4 DK 169909 B1 s angiver et savearrangement til afkortning af profilerne.The bending machine consists, in principle, of a frame 2 with a plate-shaped upper part 4 supporting the bent part of the profile during the bending process. The machine has automatic feed for the profiles, which are otherwise computer controlled for automatic bending of the profiles. The location of the bucks is determined from a counter 8 in the profile feed path. The reference numbers 10, 12 indicate a bending head and a bending actuator, respectively, while 14 4 denotes a sawing arrangement for shortening the profiles.

På tegningens fig. 2 angiver henvisningstallet 16 et afstandsprofil mellem et fast sidestyr 18 og et derimod bevægeligt andet sidestyr 20, der hver bærer overfor 5 hinanden beliggende bukkedorne 22. Det bevægelige sidestyr er fastgjort for enden af en akseltap 24 giideligt lejret i en glidebøsning 26. Sidestyret 20 er over akseltappen forbundet til en luftcylinder 28, der via styringsautomatikken aktiveres og bringer sidestyret i 10 anlæg med profilets sidekant i bukkepositionen. En bukkeskinne 30 løfter profilet op mod bukkedornene 22 for bukning deromkring. Styringsautomatikken fastlægger ligeledes bukkeskinnernes bevægelse for frembringelse af det ønskede buk, hvorefter bukkeskinnen returnerer til 15 udgangsstillingen, og det samme gælder sidestyret. Profilet fremføres derefter til foretagelse af det næste buk.In the drawing FIG. 2, the reference numeral 16 indicates a distance profile between a fixed lateral guide 18 and a movable second lateral guide 20, each carrying opposite buckling mandrels 5. The movable lateral guide is securely attached to the end of a shaft pin 24 securely mounted in a sliding sleeve 26. The lateral guide 20 is over the shaft pin connected to an air cylinder 28 which is activated via the control automatic and brings the side guide in 10 systems with the side edge of the profile in the bending position. A bending rail 30 lifts the profile up against the bending mandrels 22 for bending therethrough. The control automatic also determines the movement of the bend rails to produce the desired bend, after which the bend rail returns to the initial position, and the same applies to the lateral guide. The profile is then advanced to make the next abdomen.

En bukkedorn er i forstørret målestok vist i fig.A buckthorn is shown on an enlarged scale in FIG.

5, hvor profilets sidekant styres i spalten 32 mellem 20 hovedet 34 og sidestyrets sidevæg til stabilisering af denne under bukkeprocessen.5, wherein the side edge of the profile is guided in the slot 32 between the head 34 and the side guide side wall to stabilize it during the bending process.

Som det forstås, kan maskinen umiddelbart bukke profiler af varierende bredde, ligesom den kan bukke profiler med begrænset variation af højden pga. et vist 25 spillerum mellem dornene og bukkeskinnens overside.As is understood, the machine can immediately bend profiles of varying widths, as well as it can bend profiles with limited variation in height due to a certain clearance between the mandrels and the upper surface of the bend.

Selvom maskinen her er beskrevet specielt i forbindelse med kantprofiler til isoleringsruder, kan den naturligvis benyttes til bukning af andre tyndvæggede profiler.Although the machine is described here specifically in connection with edge profiles for insulating windows, it can of course be used for bending other thin-walled profiles.
