Definitions

  • the invention relates to a method for undulating deformation of a flat material blank according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of claim 8.
  • BE-A-548 274 describes a device in which two parallel shaft parts can be produced directly within one package. The lower rows of molds are retracted in an arcuate movement or extended again after the deformation, while the upper rows of prismatic molds can be lowered in a vertical movement.
  • a major disadvantage of the known methods and devices is that the distance or the spaces between the individual molding tools of a row always remain the same.
  • the distance corresponds to the size of the finished shaft part, which inevitably leads to a relative displacement between the end faces of the molding tools and the material cut during the deformation process.
  • the absolute length of the material cut shortens with increasing deformation, which leads to friction on the forming tools.
  • the possible uses of the previously known devices were therefore extremely limited.
  • FR-A-1,259,214 (prior art as specified in the preamble of claims 1 and 8) describes a method in which a plurality of shafts are formed simultaneously in a plate, the molding tools being pressed against one another and being pushed together at the same time.
  • the device described is not suitable for deforming small material blanks, for example within a packaging line.
  • the process should also enable high cycle times and be relatively easy to integrate into a higher-level work process.
  • Another object of the invention is to provide a device for carrying out the method, which works with simple technical means in a small space. From a procedural point of view, this task is accomplished with a method according to the patent claim Tent claim 1 and solved in terms of device with a device according to claim 8.
  • a particularly efficient way of working can be achieved if at least one movable row of molding tools is pushed or pivoted from a loading position, in which a flat material blank is placed on the end faces of the molding tools, into a deformation position, in which the moving row of a stationary row of Forming tools faces, and when after the deformation of the material blank, the movable row with the deformed material blank is pushed or pivoted into at least one delivery position in which the material blank is delivered.
  • the displacement of the molding tools advantageously takes place uniformly relative to a plane of symmetry which runs transversely to the material blank and parallel to the molding tools.
  • the molds are thus moved uniformly from both sides against the plane of symmetry. This considerably simplifies the control of the movement sequence. In certain cases, however, it would also be conceivable to push the molding tools together only in one direction.
  • the pushing together movement for the molds of the two rows is particularly easy to control when they are through one traction mechanism gear with traction mechanisms running in parallel.
  • the traction mechanism gear which can be, for example, a toothed belt, a cable pull or the like, brings about an absolutely uniform movement of the mold tools attached to it.
  • the actual drive of the molds is advantageously carried out indirectly or directly via a crank mechanism.
  • the movement that is carried out in the meandering deformity of the flat blank can thus be mechanically reproduced.
  • the drive could also take place via electronically controlled electric motors, via a cam mechanism or the like.
  • the deformed material blank In many cases it is necessary to stabilize the deformed material blank by connecting it to a carrier blank. This is preferably done in the delivery position, where a carrier blank can be provided in each case.
  • the deformed material blank can be coated with an adhesive in a coating position lying between the deformation position and the dispensing position.
  • the material blank is preferably held in place by vacuum on the front side of the movable row of molding tools.
  • the transport can take place in a rotational movement in that at least one movable row of shaping tools is fastened to a rotor which starts at individual work stations in cycles.
  • the movable row of molding tools could also gradually move to individual work stations in a linear movement and then return to the starting position.
  • FIG. 1 to 3 schematically show a stationary row 2 of molds 4 and a movable row 3 of molds 5.
  • the molds are arranged parallel to each other and have a prismatic configuration.
  • the cross-sectional shape and the length of these molding tools must of course be adapted to the shaft part to be produced.
  • the facing end faces 6, 6 'of the two rows of molds are in the starting position on one level. This level is practically formed by the flat material blank 1, which is not shown here for reasons of better clarity.
  • the reference numeral 8 indicates a plane of symmetry which runs transverse to the flat material blank and parallel to the molding tools.
  • the stationary row 2 is moved in the direction of arrow a, i.e. pressed parallel to the plane of symmetry 8 against the movable row 3 of molding tools.
  • the movable row could also be pressed against the stationary row, or both rows could be moved uniformly against one another. Simultaneously to this movement, however, the two rows of molding tools 4 and 5 are pushed together in the direction of arrow b towards the plane of symmetry 8. The middle movable molding tool 5m remains in the plane of symmetry.
  • FIG. 3 shows the molding tools in the end position in which the material blank is completely deformed.
  • the relative sequence of movements between a movable mold 5 and a stationary mold 4 is shown again in FIG.
  • the flank 10 of the stationary mold 4 with its tool edge 52 moves in a circular arc movement with the radius R against the flank 9 of the movable one Forming tool 5.
  • the radius R corresponds to the distance D between the two forming tools 4 and 5 and at the same time the height H of the desired deformation.
  • a in the plane of the end faces 6 and 6 'lying material cut evidently experiences no relative displacement to the end faces in this movement.
  • a deformation station with the various drive and transmission systems is described with reference to FIG. 5.
  • two parallel guide rods 12 and 12 ' are fixedly mounted.
  • a fixed holder 15 which carries a fixed molding tool 5m.
  • the remaining movable molds 5 are arranged on displaceable lower holders 16 which are displaceable along the guide rods 12 and 12 '.
  • a frame 11 is fixedly arranged in the rotating area of the rotor blade 64.
  • This frame carries the stationary molds 4.
  • the movable guide rods can be moved downward on the parallel guides 14, 14 'in the direction of arrow a.
  • the stationary molding tools 4 are fastened to the ends of the movable upper holders 20.
  • a drive crank 27 is arranged on the right side. This drive crank engages in a vertical fork 33 which is provided at the top and bottom with thrust elements 65 and 65 '. The function of these thrust elements is explained below with reference to FIG. 9.
  • a lower traction mechanism 17 is arranged in the displacement area of the movable lower holder. This consists of a first parallel belt 18 and a second parallel belt 19. A parallel belt is provided for each symmetrical pair of movable holders. In the present case it two pairs, the diameter of the pulleys 50, 50 'and 53, 53' are determined according to the distance to be covered by the holder. Each pair of holders is connected at a connection point 30 to the upper and the lower run of a parallel belt.
  • a rotary movement of the drive crank 27 obviously causes a pushing movement of the thrust elements 65, the holder 16r being pushed onto a driver 29 and setting the traction mechanism 17 in motion, and thereby all movable lower holders being set in motion simultaneously.
  • the upper traction mechanism 21 is set in motion via the thrust element 65 '.
  • the upper traction mechanism 21 consists of the two pairs of pulleys 54, 54 'and 55, 55', which in turn carry a first and a second parallel belt 22 and 23, respectively.
  • the movable upper holders 20 When the upper traction mechanism transmission is actuated, the movable upper holders 20 likewise perform a uniform collapsing movement, although they can still move downward in the direction of arrow a.
  • the drive crank 27 also engages in a lower horizontal fork 32 which is attached to a vertical transmission rod 36.
  • This transmission rod is guided on the guides 35, 35 '.
  • An upper horizontal fork 31 is arranged at the upper end of the transmission rod 36.
  • This is operatively connected to a rocker arm 26 which is articulated on the frame 11.
  • the rocker arm 26 has the function of a one-sided lever in that it also engages in an angle fork 34. With this gearbox the vertical Thrust movement of the transmission rod 36 with a certain reduction ratio on the movable guide rods 13, 13 'transmitted.
  • Figure 6 shows the position of the molds analogous to the position in Figure 2.
  • the two forks 32 and 33 cause a simultaneous horizontal and vertical pushing movement.
  • the horizontal thrust movement causes all the molds to be pushed together via the two traction mechanism gears, and the vertical thrust movement causes the stationary molds to be lowered between the movable molds.
  • the material blank 1 is already partially deformed, but there is no displacement to the end faces of the molding tools.
  • Figure 7 shows the end position of the molds.
  • the drive crank 27 has a movement of 90 ° from the horizontal to the vertical. With reference to FIG. 4, this movement corresponds to the path that a tool edge 52 travels until the material blank is completely deformed. This route can of course be changed depending on the desired cross-sectional shape of the deformation or the molds. From Figure 7 it can also be seen that above the rocker arm 26, the movable guide rods 13, 13 'in the parallel guide 14, 14' have been moved to the lowest position. Different path lengths are of course also possible here, depending on the gear ratio.
  • the push crank gear allows the adjustment of individual parameters in the simplest way.
  • FIG. 8 shows a device with several work stations, in which a deformation station 39 is constructed approximately according to the principle of the device according to FIG. 5.
  • a total of four movable rows 3 of molds are arranged on the rotor blades 64 of a rotor 37 in a uniform angular division.
  • the rotor can be rotated in the direction of the arrow d and thus leads the moving rows to different work stations in cycles. A certain movement is carried out simultaneously at each work station.
  • the end faces 6 of the movable molding tools 5 are provided with openings 7. These openings are operatively connected to a vacuum source, not shown here. As a result, the material blanks 1 are held on the lower row of molding tools, regardless of the relative position of the molding tools.
  • a loading station 38 flat material blanks 1 are lifted from a stack 46 and placed on the movable row of molding tools in the loading position by a mechanism (not shown here). After a rotation of 90 °, these molding tools arrive at the deformation station 39, where they are exactly parallel under the stationary row 2. In this position, the material cut is deformed according to the principle described above.
  • the now deformed material blank arrives at a coating station 40, at which an adhesive spray head 42 is arranged.
  • This spray head sprays the underside of the blank with an adhesive.
  • the lower mold tools naturally remain in the collapsed position which they have assumed at the deformation station 39.
  • another suitable device for applying an adhesive could also be provided.
  • the material blank arrives at the delivery station 41, which lies in the plane of movement of a conveyor belt 43.
  • carrier blanks 44 are fed in the direction of the arrow and are removed from a stack 45.
  • the pushed-together lower forming tools are lowered somewhat, so that the deformed material blank 1 is pressed onto the carrier blank 44 with the adhesive coating.
  • the active connection to the vacuum source is interrupted by a corresponding control and the molds are withdrawn again.
  • a finished shaft part 47 leaves the work station in the next cycle and can be processed further in a packaging line.
  • the movable molding tools are moved apart again until they have assumed their starting position.
  • This device works extremely efficiently and can be integrated into a packaging line in a space-saving manner, the production of the shaft parts 47 being able to keep up with the filling cycle without further ado.
  • other work stations could also be provided in the area of the rotating body 37. It would also be conceivable to omit the coating station 40 and instead to coat the carrier blanks 44 with adhesive.
  • FIG. 9 shows, in a highly simplified manner, the rotor control, which serves to actuate the molding tools synchronously with the rotary movement of the rotor.
  • each rotor blade 64 is assigned a push rod 28, at the end of which a fork 63 is arranged.
  • Each fork 63 engages in the driver 29 ( Figure 5) for pushing the traction mechanism.
  • the control disc 51 is in total three different Lower segments.
  • a closing segment 60 is fixed and extends over a sector of approximately 180 °.
  • An opening segment 62 is arranged axially offset on the rotor axis, which is also fixed, but which can be adjusted in the direction of arrow f during operation.
  • the opening segment 62 extends over a sector of slightly less than 90 °.
  • the remaining sector area of the control disk 51 is covered by a thrust segment 61 which is firmly connected to the thrust element 65 and to the vertical fork 33.
  • the push segment 61 can be moved from an open position in which it corresponds to the open segment 62 into a closed position in which it corresponds to the closed segment 60.
  • the following process takes place when the rotor is rotated in the direction of arrow d: the engagement element 49 rests on the opening segment 62 at the charging station 38.
  • the movable molding tools 5 then have the position shown in FIG. 5, in which they are equipped with a material blank 1.
  • the molding tools remain in this open position, since the engagement member 49 must first grip the opening segment 62 until it is transferred to the narrow subsector of the thrust segment 61.
  • the rotor blade in question has reached the deformation station 39 and the movable molds are exactly opposite the stationary molds 4.
  • the material blank is now deformed by actuating the drive crank 27 and thereby pushing the push segment 61 from the opening segment 62 to the closing segment 60.
  • the upper and lower traction mechanism gears 17 and 21 are actuated and the molding tools perform the movement already described.
  • the rotor is turned a quarter turn, wherein the engaging member 49 changes over to the closing segment 60, so that the molding tools are held in the closed position.
  • the coating station 40 is reached.
  • the rotor is rotated further by 90 °, the engagement member 49 still abutting the closing segment 60. Only after the deformed material blank 1 has been connected to a carrier blank 44 and after a further rotational movement of the rotor by a few angular degrees is the engagement member 49 in turn transferred to the larger subsector of the thrust segment 61, which still remains in the same position.
  • FIG. 10 shows a typical shaft part 47, which is produced according to the method according to the invention.
  • the material blank 1 has a regular, meandering configuration and is slightly narrower than the carrier blank 44.
