Definitions

  • the invention relates to a heating device for a welding device with two guide rails on which clamping devices for fixing the plastic pipe sections or to be welded together
  • Plastic moldings are arranged and adjustable against each other, are used in the two half-ring-shaped electrical cal heating plates which are directed towards each other with their inner receptacles and connected or connectable to each other in the region of their free ends.
  • Such welding devices are preferably used when welding plastic pipes laid in a trench. With this application there is little space for the plastic pipe sections to be connected to one another. The welding process is made even more difficult by the fact that the plastic pipe sections which are produced on a manufactured inner line often have to be applied as a protective tube and welded together.
  • a heating device with two pivotably connected heating plates is known, which is inserted perpendicular to the plane defined by the two guide rails.
  • the heating plates can be pushed apart and pushed onto the inner pipe.
  • the two guide rails of the welding device limit the opening angle of the heating device.
  • a welding device should be used in which the guide rails are at a sufficiently large distance from one another.
  • the use of such welding devices requires a wide trench. It is an object of the invention to provide a heating device of the type mentioned at the outset, with which outer tubes which have been pushed onto an inner tube can also be heated without having to use a welding device with a large distance between the guide rails.
  • the radius of the inner receptacles of the heating plates is equal to or greater than the radius of the outer dimension of an inner tube onto which outer tubes to be welded are pushed, that the radius of the outer circumference of the heating plates is greater than the radius of the External dimensions of the outer tubes that the heating plates in the region of their free ends have radially outward extensions, which are provided on the mutually facing sides with recesses for receiving the guide arms of the welding device, and that the connection points of the heating plates in the outside of these recesses areas of the extensions lying for the guide rails are arranged.
  • the heating device In the open state of the heating plates, the heating device can be pushed on parallel to the connecting plane of the guide bars without the guide bars limiting the opening area of the heating plates.
  • the inner tube can therefore have a diameter which can be much larger in relation to the distance between the guide rails, as in the case of known welding devices and heating devices.
  • the applied heating device is carried and centered by the guide rails, which considerably reduces the set-up time. Removing the heating device from the welding device is also not difficult.
  • the heating device can be constructed from two almost identical heating plates if the recesses are provided are each half divided between the two heating plates. This also makes it easier to center the plastic pipe sections or plastic fittings held in the clamping devices. For exact centering it is also provided that the mean distance between the recesses corresponds to the distance between the central longitudinal axes of the two guide rails and since the recesses are each arranged halfway to the center of the closed heating plates.
  • the heating plates can be connected to form an inseparable unit in that the heating plates are articulated in the area of the extensions, the articulated axis being perpendicular to the heating surfaces of the heating plates or because the heating plates are adjustable in the area of the one extensions, whereby the direction of adjustment is perpendicular to the parting plane of the heating plates.
  • the heating plates are secured in the closed position simply by the other extensions of the heating plate using a quick release, e.g. Toggle lever lock are interconnectable.
  • a necessary compensation movement for the heating plates is made possible by the fact that the recesses in the area of one extension are formed as semicircular or rectangular grooves in cross-section which are matched to half the cross-sectional dimensions of the guide rail and that the recesses in the area of the other extensions open towards the end of the extensions and their depth matched to half the diameter of the guide rail.
  • the heating device is held on one guide rail but can move relative to the other guide rail.
  • the invention is explained in more detail using an exemplary embodiment shown in the drawings. It shows
  • Fig. 1 in side view of the heater in the pivoted open position of the heating plates
  • the heating plates 11 and 21 are in the form of semi-annular disks, the inner receptacles 14 and 24 having a radius from the center 19 and 29, respectively, which is equal to or greater than half the outer dimension of the inner tube 40, onto which the outer tubes 41 to be welded together are pushed.
  • These outer tubes 41 are held in clamping devices which consist of the halves 43 and 44 and are held and adjustable on the two guide bars 45 and 46.
  • the alignment of the outer tubes 41 is carried out with the clamping devices on the middle l longitudinal axis 42.
  • the radius for the outer circumference 15 or 25 of the heating plates depends on the outer dimensions of the outer tubes 41, it is larger than half the outer diameter of the outer tubes 41.
  • the radially outwardly projecting extensions 12 and 16 or 22 and 26 are formed.
  • the extensions 12 and 22 form bearing eyes 18 and 28 for the pivot axis 20, which pivotally connects the two heating plates 11 and 21 to one another.
  • a sliding mechanism smus can be provided, which allows a parallel displacement of the heating plates 11 and 21 for adjustment in an open position.
  • the heating plates 11 and 12 are connected to each other so that their inner receptacles 14 and 24 are directed towards each other and form an annular disc in the closed position.
  • Guide rails 45 and 46 can accommodate. Their distance is therefore matched to the distance between the guide bars 45 and 46.
  • Recesses 13 and 23 form the receptacle for the guide rail
  • the diameter of the guide bar is 45 mm. The distance from the center 30 or 32 of the recess 13 or 23 from the center
  • Distance to the center 19 or 29 of the heating plate 11 or 21 is half the size and the distance of the longitudinal central axes
  • Guide bars 46 are quickly detachably connected to each other.
  • the heating plates 11 and 21 can de on the mutually facing sides de
  • Extensions 12, 16, 22 and 26 with coordinated Centering approaches and receptacles can be asymmetrical so that identical heating plates 11 and 21 can be used.
  • the recesses 13 and 23 can also have a semicircular cross section, which corresponds to half the cross section of the guide bar 45.
  • the arrow 36 indicates how the heating device 10 which is in the open position is pushed on, namely between the two end faces of the outer tubes 41 held in the two tensioning devices.
