Definitions

  • the invention relates to an automatic bending straightener of the type corresponding to the preamble of claim 1.
  • Such a bending straightening machine is known from DE-C-34 45 544.
  • Straightening takes place by the workpiece, e.g. the pinion shaft or camshaft is bent between two straightening pads against the stroke by the straightening punch until a permanent bend occurs that is opposite to the stroke.
  • the position of the impact is determined by rotating the workpiece by suitable measuring devices in the longitudinal and circumferential directions.
  • the size and location of the straightening stroke is determined automatically by a computer. Either a single straightening punch is shifted in a suitable manner in the longitudinal direction of the workpiece or there are several straightening dies which are actuated as required.
  • the workpiece is rotatably supported between the centers of the grains and the leveling documents remain for a specific workpiece, one of which Series should be seen at fixed points in the longitudinal direction of the workpiece.
  • the invention has for its object to design an automatic bending straightening machine of the type corresponding to the preamble of claim 1 so that any number of elements such as straightening documents can be repositioned with relatively little effort when converting.
  • the transport rod can be displaced in its longitudinal direction by a suitable drive, for example a hydraulic cylinder, and in each case coupled to one of the elements to be displaced.
  • a suitable drive for example a hydraulic cylinder
  • this element When this element has reached the target position, it is recoupled, ie the element is detached from the transport rod and coupled to the machine table.
  • the stroke of the drive does not need to correspond to the entire length of the workpiece, but only to the largest possible displacement distance of one of the elements.
  • another element is connected to the transport rod and positioned in the manner described. In this way, only a single drive is required for all elements and the design effort for positioning the entirety of the elements is correspondingly low.
  • the purpose of the invention is more completely achieved if the measuring devices (claim 2) and / or the workpiece holders, e.g. the grain tips, can be coupled with the transport rod (claim 3).
  • the coupling device by means of which the individual elements (straightening documents, measuring devices, workpiece receptacles) can be connected alternately with the transport rod and with a positioning rail connected to the machine table, can be designed in detail according to claim 4.
  • the actual coupling can be carried out by clamping devices according to claim 5.
  • An important embodiment of the invention which is also of importance irrespective of the displacement by means of a transport rod, is the slide with workpiece supports of different heights. This also enables adaptation to different workpiece diameters.
  • the positioning cams can be circumferential grooves of the rod for displacing the slide, engage in the pins that fix the slide in different positions (claim 7).
  • the transport rod of claim 1 can be smooth and performs the displacement stroke itself with the respective element coupled by clamping
  • the threaded rod is fixed in the longitudinal direction and performs a rotation instead of the longitudinal stroke, which, when a threaded element is engaged, leads to a displacement of the relevant leveling pad or the like in the longitudinal direction to the desired position.
  • the leveling pad or the like is coupled to the machine table at this position and the threaded element is disengaged from the threaded rod. If this continues to rotate, the relevant guidance document will no longer be affected and will retain its position.
  • the measuring devices and / or the workpiece holders can also have threaded elements.
  • the threaded elements can be formed according to claim 11 by a divided threaded nut, the parts of which can be removed from the threaded rod radially with respect to the axis thereof by a suitable mechanism until the threads of the threaded nut parts and the threaded rod no longer overlap.
  • the threaded element is only a thread segment which engages on one side, as a result of which the mechanical outlay for engaging and disengaging is substantially reduced.
  • the bending straightening machine designated as a whole in FIG. 1 comprises a conventional closed press frame 1, in which a press ram 3 can be raised and lowered by means of a hydraulic piston / cylinder unit 2, which bears three straightening rams 4 on its underside in the exemplary embodiment.
  • a machine table 5 can be raised and lowered by means of a hydraulic piston / cylinder unit 6, on which two workpiece receptacles 7 in the form of center points, which engage in corresponding recesses in the ends of a rod-shaped workpiece 10, straightening documents 8 which hold the workpiece 10 are supported against the force of the straightening plunger 4 acting on it from above, and measuring devices 9 are attached which scan the circumference of the workpiece 10 and, when the workpiece 10 is rotated by means of a rotary drive 49 (FIG. 7b), determine a blow by the same Counterbending must be compensated for by the straightening punch 4 or at least reduced.
  • a hydraulic piston / cylinder unit 6 on which two workpiece receptacles 7 in the form of center points, which engage in corresponding recesses in the ends of a rod-shaped workpiece 10, straightening documents 8 which hold the workpiece 10 are supported against the force of the straightening plunger 4 acting on it from above, and measuring devices 9 are attached which scan the circumference of
  • the elements 7, 8, 9 are clamped on a positioning rail 11, which is attached to the top of the machine table 5.
  • the workpiece 10 is shown only schematically in FIG. 1 as a cylindrical body. In practice, the outline is quite irregular. For example, around camshafts, drive shafts for motor vehicles, pinion shafts or the like. act. However, there are cylindrical sections distributed over the length, on which the workpiece 10 lies on the straightening supports 8 and on which the measuring devices 9 also engage.
  • the arrangement of the elements 7, 8, 9 shown in FIG. 1 is based on a specific workpiece 10 and can remain unchanged as long as a series of identical workpieces is straightened.
  • a measuring device 9 is shown as an example, which engages with a button 12 on the underside of the workpiece 1o.
  • the measuring device 9 is of a known type and is therefore not described in further detail. It is fastened by means of a screw 13 and a pin 14 on the upper side 15 of a coupling device 20.
  • the coupling device 2o comprises a housing block 16 composed of several parts, which has a passage 18 for the positioning rail 11 which runs parallel to the axis 17 of the workpiece 10.
  • the positioning rail 11 and corresponding to the passage 18 have a dovetail cross-sectional shape.
  • a passage 19 is provided in the housing block 16 which runs parallel to the axis 17 and is penetrated by a transport rod 30 which also runs parallel to the axis 17 and is displaceable in its longitudinal direction.
  • the positioning rail 11 acts as a whole designated 21, arranged in the coupling device 2o clamping device, which comprises a cylinder 22 mounted in the housing block 16 and a piston 23 displaceable therein, which has a clamping piece 24 against the edge 11 'of the positioning rail 11 acts.
  • the piston 23 is advanced by a fluid pressure medium, which is brought in via a connection 26.
  • a clamping device which is arranged in the housing block 16 and is designated as a whole by 27, acts in a corresponding manner against the transport rod 30, which comprises a cylinder 28 running transversely to the transport rod 30 and a piston 29 which can be displaced therein and which, via a pressure piece 31, acts against the in FIG. 2 left side of the transport rod 3o acts.
  • the fluid pressure medium required to actuate the piston 29 is supplied via a connection 32.
  • the control is carried out in such a way that pressure is only present at one of the connections 26 and 32, so that the coupling device 2o is connected either to the positioning rail 11 or to the transport rod 3o.
  • the coupling device 2o and the measuring device 9 arranged thereon are displaced into a new desired position when the transport rod 3o is displaced longitudinally along the positioning rail.
  • the transport rod 3o is decoupled and the coupling device 2o is coupled to the positioning rail 11, whereupon the transport rod 3o is coupled to another measuring device and the latter can be brought into its new target position.
  • Coupling devices corresponding to the coupling device 2o of FIGS. 2 and 3 serve not only to carry the measuring devices 9, but also to carry the workpiece holders 7 and in particular the straightening documents 8.
  • FIGS. 4 to 6 An example of this is shown in FIGS. 4 to 6.
  • the straightening pad 8 comprises a base plate 33 connected to the coupling device 2o, on which a slide 34 on guide rods 35 can be displaced transversely to the axis 17 of the workpiece 1o.
  • four different workpiece supports 36, 37, 38, 39 are arranged on the top of the slide 34, which leave a free space 4o in the middle. 17 characterizes the workpiece axis, i.e. the connecting line of the center points of the workpiece receptacles 7.
  • the slide 34 is brought into such a position that the intermediate space 40 is located under the axis 17, the workpiece 10 is not supported at all at the relevant location. If one of the workpiece supports 36, 37, 38, 39 is brought under the axis 17, support is provided there, the selection of the workpiece support being based on the diameter present there for the workpiece in question.
  • the carriage 34 is displaced by means of a rod 41 which extends in the direction of displacement and which has circumferential grooves 42, 43, 44, 45 at corresponding intervals in the spacings of the workpiece supports 36, 37, 38, 39.
  • a small lifting cylinder 46 acting parallel to the rod 41 is connected to the base plate 33, on the piston rod of which a lifting cylinder 47 acting transversely to the rod 41 is arranged, the free end of the piston rod 48 engaging in the circumferential grooves 42, 43, 44 or 45 .
  • the lifting cylinder 46 performs a stroke that corresponds to the distance between two adjacent circumferential grooves 42, 43, 44, 45. He takes the rod 41 by a distance when the piston rod 48 is advanced and can thus gradually move the slide 34 so that one of the elements 36, 37, 38, 39, 40 is located under the axis 17.
  • Fig. 7b shows the same thing, which is shown very schematically in Fig. 7a. It can be seen that the transport rod 3o is displaceable by a hydraulic drive 5o acting in its longitudinal direction. The arrangement is in FIG. 7b in the position required for straightening the workpiece 10 according to FIG. 7a.
  • the arrows 51, 52, 53 symbolize the presence of pressure on the connections 26 for clamping the workpiece receptacles 7 or the element 8, 9 on the positioning rail 11.
  • the transport rod now carries out an idle stroke to the right and is then connected by pressure at 55 to the leveling pad 8 (and the measuring device 9 attached to it), in order to then be shifted to the left and to bring the leveling pad 8 to its new position.
  • the straightening base 8 is fixed by pressing at 56, whereupon the transport rod 3o is idle moved to the left, the left workpiece holder 7 is coupled to the transport rod 3o by pressing 57, and the left workpiece holder 7 is coupled into the new desired position according to FIG 7e shifts, whereupon pressure is again applied to the connection 26 corresponding to 51, and thus all the elements 7, 7, 8 are locked in their new position, after which the shorter workpiece 1o 'of FIG. 7f can be straightened.
  • the slide 34 is moved in the transverse direction if necessary in order to bring the required workpiece base 36, 37, 38, 39 into position.
