Definitions

  • the invention relates to a drum for receiving a cable of an actuation and / or weight compensation device for a door leaf on its outer surface, which has a helically progressing guide groove in the drum circumferential and drum axis directions, into which the wound rope is guided in a single layer, the drum shell wall of which is a sheet metal, in which the guide groove is pressed in such a way that the sheet metal in the region of the drum casing wall, seen in the cross section through the drum axis, is formed in an essentially undulating manner, the troughs appearing on the outer casing surface having the cross section of the guide groove and which the troughs of the inner surface of the jacket facing the drum axis are radially opposite the raised zones between the adjacent groove windings.
  • the invention also relates to a method for producing such a drum.
  • Such drums are used in particular for ropes that are part of an actuation and / or weight compensation device for a door leaf, especially one that is moved overhead and consists of links that are articulated in succession in the direction of movement.
  • drums provided with guide grooves for the rope are circular-cylindrical, conical or alternatively from a circular-cylindrical shape to 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 diameter of the cable turns.
  • 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 thus complex and their weight is still relatively high even in the case of cast aluminum.
  • a known drum of the type mentioned - DE-C-393583 - is provided with a jacket made of sheet metal, in which the helically progressing guide groove for receiving the rope is pressed or rolled.
  • This sheet metal jacket has to be supported on the drum shaft by means of side walls or the like leading to the shaft, if necessary by means of a support body, so that a correspondingly large number of parts to be connected with one another is required with corresponding handling effort.
  • 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 those according to the prior art.
  • this object is achieved according to the invention in that one of the drum end walls is formed in one piece with the sheet of the drum shell wall and also in one piece with the shaft shell formed from the sheet of the drum shell wall in the axial direction thereof to hold on to the Has drum penetrating shaft.
  • drum shell wall of the guide groove formation for the rope is integrally formed with a drum end wall and this adjoining axle hub, so that, if necessary, only the other drum end wall - preferably with an integral subsequent hub hub - is provided as an additional part for forming the drum.
  • the production takes place without cutting in a pressing process, which causes flow deformation of the sheet. This results in an essentially undulating shape in the longitudinal section through the drum axis in the region of the drum casing wall.
  • the drum jacket wall with the one drum end wall along with the associated axle hub is made from a sheet metal which is converted from an essentially flat starting shape into the drum shape by flow deformation. Radially protruding, integrally adjoining collars can be formed on the two end edges of the drum shell wall. The production then proceeds in such a way that the sheet metal in the area of this drum front wall or in a radially inner one Area held in the processing machine and is preferably set in rotation about the axis of the drum to be manufactured via this holding engagement.
  • the molding tool acting on the sheet metal rotate about this drum axis and to keep the sheet metal stationary, but preferably the sheet metal 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 usually 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.
  • 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 stamping 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 moved towards one another and are guided in their entirety following the guide groove pitch 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 moved towards one another and are guided in their entirety following the guide groove pitch 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
  • 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 optionally the front collar and the like are formed in one or in a separate subsequent operation, the latter also in the latter first pressing process can be formed.
  • the contour of the circular cylindrical or conical wall profile of the drum shell 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 shell wall to be produced.
  • different relative speeds can be provided, for example, first of all, with a high relative speed or rotational speed of the sheet metal part, the shaping of the drum shell wall contour and then, at a slower speed, the stamping of the guide groove.
  • 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 course on its outer surface and whose other from the radially outside on the preformed sheet metal profile roller has the appearance on the outer surface of the drum shell wall guide groove web profile, with the drum radius, so that a in the drum axis direction movement component of such a grooved molded part is unnecessary. If we are talking about profile here, then in the sense of a line following the surface of the profile 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.
  • the three exemplary embodiments shown in the drawing are each based on a drum, as can be seen in the basic structure from 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 end 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 then followed by the end face wall 3 without any compression deformation, whereupon the further cladding is formed.
  • a Matrix which supports the front side wall 3 from the inside of the drum in a manner not shown and has the negative contour on its outside of the jacket, which is shown on the inside of the jacket 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 shell 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 axially and non-rotatably connected 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 when high torques are to be transmitted.
  • the drum casing wall 2 is provided with a helical guide groove 8, the groove formation of which serves to accommodate a rope (not shown) on the outer surface 9 of the drum casing 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 roughly 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 windings from one another.
  • 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 front 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 front 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 formed end wall 4.
  • this end wall 4 is provided with the collar 16 of the side edge by spot welds 19 distributed over the circumference 18 of the drum shell wall 2 firmly connected. In this way, the drum is supported on both ends 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 another 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.
  • Figure 3 shows a partial section corresponding to Figure 2, in which the connection of the side edge 18 with the outer peripheral edge 21 'of the separate end wall 4 is accomplished with the aid of pressure-forming formations 22 distributed over the circumference.
  • the pressure-forming 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 as seen from the axial center of the drum outwards.
  • the collar 16 ⁇ also has an axially projecting centering edge 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 connected in a rotationally fixed manner to the drum, as is known in the prior art.
  • the drum is designed in the form of a circular cylinder 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.
