Definitions

  • the invention relates to a method and a device according to the preamble of claim 1 and claim 4, respectively.
  • Plastic strips are inserted between the outer profile and the inner profile, which consist of metal, in order to avoid condensation on the inner profile, which is to be prevented by the insulating properties of the plastic strips.
  • the two end edges of the plastic strips expediently have a dovetail-shaped cross section, which in the fully assembled state are fixed in correspondingly shaped grooves in the inner profile and in the opposite outer profile of the metal windows or metal doors.
  • at least one of the metallic side webs forming these grooves which are generally formed in one piece with the metal profiles, is expanded so that the dovetail profile can be inserted loosely and axially into the groove. Then these webs are bent.
  • rollers which are adapted in diameter and in the bevel to the plastically deformable metal webs in such a way that they press the inner plastically deformable metal web in the direction of the dovetail-shaped edges of the plastic strips when passing through the space between the two profiles.
  • the opposite, the same groove associated edge of the metal profiles is rigid, and both inwardly projecting edges of the metal webs form acute angles to the plastic strips, so that the opposite edges penetrate into the elastically deformable plastic profile and thereby produce a stable fixing and sealing .
  • Two essentially parallel plastic strips are expediently provided.
  • opposite guide edges can be provided, which can have an essentially triangular cross section, the tips of which face one another.
  • the assembly rollers passed between the two metal profiles can then produce a precisely defined sealing connection between the plastic profiles and the metal webs of the inner profile and the outer profile.
  • the web-shaped metal strips have been knurled.
  • a toothed knurled roller is pressed onto the inward web edges of the inner metal web, so that the teeth in the material cause corresponding depressions and deformations. This results in a significantly better connection and sealing between metal profiles and plastic strips.
  • the invention is based on the problem of designing a method and a device according to the preamble of claim 1 and claim 4, respectively, in such a way that the required pressing forces between web edges and plastic strips can be reduced, that knurling and sealing pressing of the web edges against the plastic strips in one Operation can take place, and that larger loads on the finished connection, in particular due to high temperature during powder coating, can be avoided after the sealing connection has been made.
  • the method according to the invention essentially consists in the fact that initially only a loose connection between the outer profile and the inner profile takes place via the plastic strips, the metal webs being designed such that the dovetail-shaped edges of the plastic strips can be inserted loosely and axially parallel to the profile edges.
  • These profiles are then further processed, in particular anodizing and painting. Because of the only loose connection, a better outflow of the individual treatment substances such as degreasing baths, cleaning baths, anodizing baths, compression baths and the like is possible.
  • the anodizing or painting of the profile strips which have not yet been fully assembled into a frame also considerably simplifies this work, since individual profile strips are considerably easier to handle than rectangular frames. Due to the usual calculation method, which refers to the enclosed area, such as the window area, this method, which is limited to the profile strips, also results in considerable financial savings in further processing such as painting, anodizing, etc.
  • the final sealing connection between the metal profiles and the plastic strips can take place before, but preferably only after the surface treatment, in particular in the case of hot powder coating.
  • a special roller device referred to as a "mouse” is passed through the cavity between two plastic strips, which is designed such that knurling of the facing web edges of the metal webs takes place first, and then the web edges are pressed against the plastic strips by further rollers.
  • Knurling and / or sealing pressing can take place by means of a plurality of coordinated rollers which are freely rotatably mounted on a common rail, preferably together with guide rollers.
  • rollers arranged in pairs While one of the rollers arranged in pairs comes into engagement with the web edge of the inner profile as it is pulled through, the subsequent roller engages with the outer profile, which is made possible by a slight axial displacement of adjacent rollers on the rail. Adjacent roles are rotated in the opposite direction. Only then are the strips thus finished assembled in the usual way to finished window frames or door frames.
  • the further treatment in particular the powder coating at elevated temperature
  • the seal and the strength in particular with respect to axial thrust forces between metal profiles and plastic strips, can be increased, since a reduction in the strengthening by subsequent heating can be avoided.
  • This improvement also leads to a reduction in the required contact forces and thus to greater protection of the material or the possibility of using less high-quality and therefore cheaper material.
  • the possibility of knurling and sealing connection in a single step leads to a further considerable simplification of the production of the profile strips and thus also the metal window frames or door frames.
  • a metal outer profile (1) is shown with an outward smooth surface, further an inner metal inner profile (2).
  • Two parallel plastic strips (3, 4) are arranged between the two.
  • the inner metal profile (2) like the outer metal profile (1) for the engagement with the outer plastic profile (3), has a fixed, edge-shaped metal web (6) and a plastically deformable metal web (8), which is separated and separated by a groove, the groove formed therebetween with an approximately triangular or dovetail cross section is filled through the dovetail end edges of the plastic strip (3) when assembly is complete.
  • Opposing webs (6, 8) of the outer profile (1) and the inner profile (2) are identified by the same reference numerals.
  • the second plastic strip (4) which is arranged parallel to it on the inside, and the corresponding ones fixed edge-shaped metal webs (7) as well as the plastically deformable associated metal webs (9) and the dovetail-shaped edges (5) of the plastic strip, which are pressed in sealingly in corresponding grooves which were created by the two assigned metal webs. From Fig. 1 it can also be seen that the two inward edge ends of the associated metal webs taper approximately, and that the deformable metal web (9) has knurls towards the dovetail-shaped end section of the plastic strip.
  • the inner metal profile (2) and the outer metal profile (1) have support strips (14) exactly in the middle between the two plastic strips (3, 4) 15 ') with an essentially triangular cross-section, the tips of the triangles being aligned with one another in order to form an exact guide for the rollers between the falling edges of these support strips and the plastically deformable webs.
  • the inside, plastically deformable and edge-shaped metal webs are pressed against the plastic webs, whereby at the same time, of course, the opposite rigid edge (6 or 7) is also pressed onto the opposite surface of the plastic strips (3, 4) .
  • Fig. 1 shows the finished final state of the profile strip, but not the raw state, in which the plastically deformable webs (8, 9) are widened somewhat to allow axial insertion of the plastic strips (3, 4) into the two opposite grooves and to ensure a loose fit.
  • a web roller (21, 22) is first guided in the space between the deformable metal bar (9) and plastic bars (3, 4), preferably made of polyamide, in the direction of the arrow
  • plastic bars (3, 4) preferably made of polyamide
  • a pressure roller (15, 16) presses the plastically deformable metal webs (8, 9) from the outside in the edge area towards the plastic strips (3, 4) and enables a permanent, sealing connection that is stable against shear forces.
  • the pressure roller (15, 16) rolls and does not rub it has an axially outer disc (26) with circumferential teeth.
  • Guide rollers (23, 24; 17, 18) are provided on both sides of the treatment rollers (15-22).
  • an inclined edge (10) is provided on the inner profile (2) for receiving a sealing lip, likewise a cavity (11) on the outer profile (1) for receiving a further sealing strip around the schematically indicated window frame (12) or door frame to seal.
  • a sealing lip is provided on the inner profile (2) for receiving a sealing lip
  • a cavity (11) on the outer profile (1) for receiving a further sealing strip around the schematically indicated window frame (12) or door frame to seal.
  • the section (13) of the outer profile (1) and the section (14) of the inner profile (2) are walled into the wall.
  • Fig. 2 shows a perspective top view of a device for the simultaneous knurling and sealing pressing of the metal webs (8, 9) to the plastic strips (3, 4) in the form of a strip (27) also called a mouse.
  • the individual, differently designed and differently arranged rollers are designated by (15 to 24).
  • 15 to 24 disc-shaped rollers (15 and 16) can be seen which have discs (26) with a sawtooth edge separated from the rest of the region (25) on the outer circumference by an annular groove.
  • Guide rollers (17, 18; 23, 24) are also provided at the beginning and end of the bar (27). Following the initial guide rollers (23, 24), web rollers (21, 22) are provided, which push the plastic strips (3, 4) away from the plastically deformable metal web (8, 9); this is followed by knurled rollers (19, 20) which press on the inner edges of the deformable metal webs (8, 9) before the sealing connection is carried out via the pressure rollers (15, 16). This is followed by further guide roles (17, 18).
  • Fig. 3 shows a cross section of a pressure roller with an oblique pressure section (25) and an axially outer disc-shaped roller (26) with a saw tooth circumference (29) to ensure a rolling movement despite high contact pressure.
  • Fig. 4 shows a section along the line IV-IV of Fig. 2.
  • the disc-shaped knurled roller (19) shown there is used to press on the inner edge of the plastically deformable metal web (8, 9) to achieve an impression knurling.
