Definitions

  • the invention relates to a drum for receiving a rope with the features of the preamble of claim 1.
  • Such drums are used in particular for ropes that are part of an actuation and / or weight compensation device for a door leaf, in particular one that is moved overhead and consists of successive, articulated links.
  • drums provided with guide grooves for the rope are circular-cylindrical, conical or alternatively of a circular-cylindrical shape into a conical shape, in the context of the conical shape a progressive increase in the diameter can be provided, so that a corresponding spring force line can be compensated for by the differently increasing rope winding diameter.
  • Such drums are known, specifically in the form of cast parts, in particular die-cast parts, also made of light metal alloys. The manufacture of such drums is therefore complex and their weight is still relatively high even in the case of cast aluminum.
  • the invention has for its object to provide a drum of the type in question, which is easier and cheaper to manufacture and may also be lighter than that according to the prior art. Starting from a drum with the features of the preamble of claim 1, this object is achieved according to the invention by its characteristic features.
  • At least the wall of the drum shell with the guide groove formation for the rope is made from a metal sheet which is formed without cutting, in a pressing process which causes flow deformation of the sheet metal.
  • the longitudinal section through the drum axis in the region of the drum shell wall results in an essentially undulating shape, the troughs appearing on the outer surface of the shell having the cross-section of the guide groove and the troughs present on the inner surface of the shell facing the drum axis Raised zones appearing on the outer surface lie radially opposite one another between the adjacent groove windings.
  • At least the drum casing wall is made of sheet metal which is converted from an essentially flat initial shape into the casing shape by flow deformation.
  • Radially protruding, integrally adjoining collars can be formed on the two front edges of the drum jacket wall.
  • one of the drum end walls is formed in one piece with the drum jacket wall or the adjoining collar. The production then proceeds in such a way that the sheet metal in the region of this drum front wall or in a radially inner one Area held in the processing machine and is preferably rotated about this axis of the drum to be manufactured via this holding engagement.
  • the molding tool acting on the sheet it is fundamentally possible for the molding tool acting on the sheet to be designed to rotate about this drum axis and to hold the sheet stationary, but preferably the sheet is set in rotation, while at least the molding tool acting on the outer surface of the drum shell wall to be formed does not rotate about the drum axis.
  • the direct attack of such a tool, between which and the sheet metal a relative movement takes place, is generally carried out via one or more rolling elements, in order to avoid a frictional attack.
  • the molding tool has at least one tool part which engages on the outer surface of the drum casing wall to be formed.
  • a die on its outer surface, which has the negative profile of the guide groove and is arranged coaxially to the drum axis and adapted to the inner cylinder and / or cone shape, against which the sheet is moved by a pressure tool part acting on the outer surface and follows the profile profile of the guide groove is pronounced.
  • the pressure tool part carries out a feed corresponding to the pitch of the helical guide groove in the drum axis direction depending on the relative speed between the sheet and the embossing tool.
  • the die which is arranged coaxially to the drum axis, can rotate together with the sheet metal at the same speed.
  • a further embodiment can work with a set of rollers consisting of profiled rollers engaging on the outside and inside of the drum shell wall, which can be displaced towards one another and are guided in their entirety following the guide groove inclination with a movement component in the drum axis direction, in such a way that the sheet metal region of the drum shell wall which is accommodated therebetween is coordinated of slope and peripheral speed is formed with the guide groove.
  • a set of rollers consisting of profiled rollers engaging on the outside and inside of the drum shell wall, which can be displaced towards one another and are guided in their entirety following the guide groove inclination with a movement component in the drum axis direction, in such a way that the sheet metal region of the drum shell wall
  • a - in particular essentially flat - sheet metal disk into the drum shape with a insofar to carry out separate front tool with which the sheet is first converted into the shape of the circular cylindrical, conical or successively circular cone-shaped drum shell wall, while subsequently the guide groove and, if appropriate, the front collar and the like are formed in one or in a separate subsequent work step, the latter also in the first pressing process can be formed.
  • the contour of the circular-cylindrical or conical wall profile of the drum jacket preferably corresponds approximately to the longitudinal section connecting line in the outer, inner or intermediate peripheral region of the waveform of the guide groove profile of the drum jacket wall to be produced.
  • the part of the mold which characterizes the formation of the guide groove can be made without regard to a rough shaping of the sheet in the axial direction, up to the formation of profile rolls, one of which is arranged coaxially to the drum axis and has the negative profile of the guide groove on its outer surface and whose other from the radially outside on the preformed sheet metal profile roller has the guide groove web profile appearing on the outer surface of the drum shell wall, namely with the drum radius, so that one in the drum axis direction movement component of such a grooved embossed molding is unnecessary. If we are talking about profile here, then in the sense of a line following the profile surface in the longitudinal direction.
  • embossing work that forms the guide groove formation can also be carried out with other shaping tools as described above, for example with the aid of a roller set.
  • a starting point for drum production can also be a tube made of sheet metal that is welded seamlessly or longitudinally or spirally - preferably using the fusion welding process, for example with the help of a laser beam .
  • a tube can not only be shaped in terms of the shape of the groove profile itself, but can also be shaped in the course of this machining into a cone or partial cone shape with or without a progressive diameter profile and can also be provided with end-side edge configurations which limit the receiving area of the single-layer guided cable holder and serve the attachment of end walls.
  • the three exemplary embodiments shown in the drawing are each based on a drum, as can be seen from the basic structure of FIG. in which one of the end walls is integrally formed with the drum shell wall. This corresponds to the manufacture of the drum from an approximately flat sheet metal disc by attacking a pressing tool which is guided from this end face in the axial direction to the other face edge of the drum, taking into account the guide groove course to be formed in the region of the drum shell wall.
  • the drum designated as a whole by 1, has a drum casing wall 2 which, in the drawing, integrally merges into an end wall 3 on the left-hand side, while at the axially opposite side end region it has a separate, i.e. is not completed in one piece with the end wall 4 provided on the drum jacket wall 2.
  • the end face wall 3, which is formed in one piece with the jacket wall 2, has an axle hub 5, which is formed in one piece with the end face wall 3 and can be formed in the course of the pressing process.
  • This is possible, for example, in that a flat sheet-metal washer is gripped by a turning tool in the mouth area encompassed by the axle hub 5, whereupon a pressing tool is moved in the axial direction of the drum from the clamping point and forms the circular-cylindrical wall of the axle hub 5.
  • This is followed by the end face wall 3 without any compression deformation, whereupon the further cladding is formed.
  • a Matrix which supports the end wall 3 from the inside of the drum in a manner not shown and has on its outside the negative contour, which is shown on the inside of the wall 2 due to the course of the guide grooves, as will be explained in more detail below.
  • a pressing tool engaging the sheet metal disk is then tracked following the contour of the outer surface of the drum casing wall 2 and taking into account the gradient of the guide groove course with radial and axial pressure following the die contour in such a way that the guide groove course results.
  • the separate end wall made of sheet metal can also be equipped with a hub extension 6, which can optionally also be formed in one piece by pressing on the end wall 4.
  • the axle hub 5 is penetrated by a screw 7, which is screwed into a bore in the hollow axis, not shown, of a shaft carrying a weight compensation torsion spring, so that the drum is connected axially and non-rotatably to the hollow hub.
  • a similar screw device can also be provided in the area of the hub extension 6.
  • the axle hub 5 and / or the hub extension 6 can also be designed as separate parts to be connected to the sheet, for example made of die-cast, especially if high torques are to be transmitted.
  • the drum jacket wall 2 is provided with a helical guide groove 8, the groove formation of which serves to receive a rope (not shown) on the outer surface 9 of the drum jacket wall 2.
  • the guide groove 8 is pressed into the sheet of the drum shell wall 2 with flow deformation, so that the wall 2 seen in longitudinal section in a material and weight-saving manner approximately wavy course, as can be seen from the upper half of Figure 1.
  • the troughs 10 appearing on the outer surface of the wall 2 form the receiving areas of the guide groove windings for the engagement of the rope, not shown, while the inner surface 12 of the drum shell wall 2, seen from the drum axis 11, has troughs 13 which, viewed in the radial direction, have the Outer surface 9 lie opposite zones 14, which separate the troughs 10 of the guide groove turns.
  • the wave troughs 10 and raised zones 14 which can be seen from the upper cross-sectional illustration in FIG. 1 merge into closed peripheral regions in the course of the course of the guide grooves 8.
  • the drum jacket wall 2 is provided on the side edge 17 adjoining the one-piece end wall 3 with a radially projecting collar 15, which correspondingly laterally delimits the receiving area of the drum jacket wall 2 for the rope and the one-piece transition between the jacket wall 2 and the end wall 3 forms.
  • the axially opposite side edge 18 is also formed in the form of a collar 16 projecting radially outward and serves to fasten the separately designed end wall 4.
  • the drum shell wall 2 firmly connected. In this way, the drum is supported on both sides of the hollow shaft, not shown.
  • FIG. 2 shows a partial section of the upper right connection area between the drum jacket wall 2 and the separate end wall 4, which illustrates a different type of connection instead of welding.
  • the radially projecting collar 16 ' is longer and, after the separate end face 4 has been applied, is flanged around its peripheral edge 21, which flanging is denoted by 20.
  • This flanging can be designed to be continuous over the circumference or to be carried out separately in sections distributed over the circumference.
  • FIG. 3 shows a partial section corresponding to FIG. 2, in which the connection of the side edge 18 to the outer peripheral edge 21 'of the separate end wall 4 is accomplished with the aid of pressure-forming designs 22 distributed over the circumference.
  • the pressure joining formations 22 are carried out from the peripheral edge 21 'of the end wall 4 in the collar 16' of the side edge 18 of the drum shell wall 2, so that there are projecting areas towards the axial center of the drum.
  • the peripheral edge 21 'of the end wall 4 and the collar 16' are slightly bent axially seen from the axial center of the drum outwards.
  • the collar 16 ′′ also has a centering edge protruding in the axial direction for receiving the end wall 4.
  • the drum shown in its entirety in FIG. 1 is used to hold a rope that is connected to its end running from the drum is fastened to an overhead door leaf in order to create a weight compensation device for the door leaf with the aid of a torsion spring which engages non-positively on the hollow shaft, which is not rotatably connected to the drum, as is known in the prior art.
  • the drum is circular cylindrical in a first region 23, which is followed by a conical region 24 which, seen from the circular cylindrical region 23, is formed with a progressively increasing diameter.
