Definitions

  • the invention relates to a device for rolling with a drive device for a workpiece to be rolled and with at least one movable rolling device, at least containing a tool holder with a rolling element and a tool holder with a support element.
  • Such devices can be used, for example, for deep rolling or smooth rolling of shafts, shaft shafts, axes, transition radii which arise when changing from one workpiece area to another workpiece area of a different size or position, and they have become particularly well known and widely used and proven in practice the form of so-called Crankshaft rolling machines. They are also fully described in the literature. For this purpose, reference is made, for example, to DE-OS 33 33 603. The cited reference shows a deep-rolling machine of the type mentioned for rolling the transition radii on crankshafts.
  • DE-PS 31 08 746 A similar machine is also shown in DE-PS 31 08 746. Both devices have deep rolling devices which are suspended and arranged in such a way that master shafts are not required to hang and guide these deep rolling devices. This type of suspension has certain advantages when adapting the devices to different types of crankshafts with different journal positions and different stroke sizes.
  • DE-PS 32 24 286 or DE-PS 31 08 780 there are also devices of the generic type that carry the deep rolling devices over master shafts, such as DE-PS 32 24 286 or DE-PS 31 08 780 can be found.
  • crankshafts of different types can be rolled.
  • the rolling tools used in the facilities are closely specialized to the rolling task intended for them, so that it is necessary to change the rolling tools even when the workpiece has small dimensional changes in the area to be rolled. For this purpose, the machine must then be stopped and the tools are replaced manually on each rolling device. Devices of this type are therefore only suitable for producing medium to large series, but can be easily converted in particular to crankshafts of different types. However, the production of small series is uneconomical.
  • the invention is therefore based on the object of using devices of the generic type to achieve an increase in efficiency by reducing the time required for machining a workpiece and / or in retrofitting the machine, by a cheaper construction of the necessary equipment and by a larger one Flexibility of such a facility.
  • At least one tool carrier is provided with at least one further rolling element and / or support element, with at least one rolling element being changeable in at least two positions, of which at least one position is a working position, with at least the rolling element and / or at least one associated supporting element being kinematically associated with a Power actuator is connectable or connected.
  • the respective rolling device is movable and is connected to only one power actuating device ensures that only the rolling force occurs as a transverse force on the workpiece and is canceled out there. Additional lateral forces that could stress the workpiece and that result from the power actuation device are largely avoided.
  • greater flexibility of the device is achieved because, within a certain frame, the device according to the invention can react to the design of the workpiece with a corresponding change in position of the rolling elements and / or the support elements.
  • At least one rolling element and / or support element is arranged on the tool carrier in a variable position.
  • the fact that at least one rolling element and / or support element is arranged in a positionally variable manner on the tool carrier can simplify the construction of the device, at least in certain applications, and this positional variability can at the same time facilitate the introduction of a workpiece into the device. Due to the change in position mentioned, it is not only possible if necessary. bring different elements to the place of use, but it is also possible to remove corresponding elements from the place of use and return them to the place of use after inserting a workpiece.
  • each rolling element and each support element is an element of a roller head.
  • Roller heads with rolling elements are already known and have proven themselves.
  • the use of such roller heads in a device of the type according to the invention further increases the economic viability of a device of the type according to the invention in that the supply of spare parts can be reduced and can essentially be limited to the roller heads. Also enables light the use of such roller heads a simpler construction of the facility.
  • a supplementary embodiment is again seen in the fact that an independent roller head is provided for each rolling element or pair of rolling elements and / or for each supporting element or pair of supporting elements.
  • the structure of the roller heads can be standardized, so that the same roller heads can always be used even on machines with a different number of roller elements used, so that the different number of roller elements is achieved simply by varying the roller heads.
  • each roller head is arranged in a variable position on the associated tool carrier. This is an easy way to bring the respective roller head into a desired position.
  • At least one tool holder is provided with a tool holder that can be changed in position in at least two predetermined or predeterminable positions, with at least one rolling element or support element that extends over the tool holder in said positions can be brought, wherein at least one rolling element in the working position and / or at least one associated support element can be kinematically connected or connected to a force actuating means.
  • a position-changeable tool holder, equipped with corresponding rolling elements or supporting elements, is easy to implement in terms of design. It succeeds at the same time To carry and guide rolling elements and support elements.
  • the tool holder be designed as a roller head for the rolling element and / or the support element. In this way it is possible to realize the inventive idea even in structurally restricted conditions. The overall structure is thereby simplified at the same time.
  • At least one tool holder carries at least one roller head.
  • different equipment of the machine can be achieved in adaptation to certain production conditions and, on the other hand, it is at least partially possible to use existing roller heads.
  • roller heads are arranged in variable positions in at least two positions, of which at least one position is the working position.
  • a supplementary alternative of the invention provides that the roller heads are arranged on a guide for changing the position. This is a space-saving and simple construction for changing the position. The roller elements and / or support elements are then changed in their position at the same time with the roller heads.
  • an actuating device is provided for carrying out the change in position, in which case it is further proposed that at least one fluid-actuated piston-cylinder unit is provided as the actuating seal.
  • Actuating devices specially adapted to the implementation of the change in position and appropriately designed and arranged are easy to implement and facilitate the implementation of the change in position.
  • At least one more position is predefined and predeterminable for the tool holder than it carries roller heads.
  • the movable rolling device consists essentially of two scissors-like arms which are kinematically connected to a force actuating means for generating the rolling force.
  • a force actuating means for generating the rolling force Such a configuration allows high rolling forces to be exerted on the workpiece in a small installation space, these rolling forces canceling each other out on the workpiece itself, so that one of the rolling forces resulting additional undesirable radial loading of the workpiece is prevented.
  • the scissor-like connection of the arms does not have to mean that a hinge point is present approximately in the middle of the arms. It is quite possible to also use the hinge point z. B. to put on one end of the arms and thus connect the ends of the arms together.
  • At least one rolling device is provided, with at least one rolling element and / or at least one support element, that in each case a fixed position is arranged in relation to the associated tool carrier.
  • the rolling elements and / or support elements must then be arranged in a fixed position in relation to the associated tool carrier.
  • a device of the type according to the invention can be equipped with one as well as with several rolling devices.
  • the rolling devices can also be of different types.
  • the workpiece can be driven centrally via a separate workpiece drive.
  • crankshafts it is also possible, in particular in the case of crankshafts, for the workpiece to be carried on the one hand by the different rolling devices and to be driven on the other hand.
  • a crankshaft is advantageously carried and guided by the rolling devices for the main bearings and driven by the rolling devices for the connecting rod bearings.
  • rolling devices for the main bearings are not absolutely necessary as a means for storing and guiding the crankshaft.
  • Driving the crankshaft via the connecting rod bearings is particularly advantageous when the rolling devices are carried and moved by master shafts.
  • rolling devices of the type according to the invention with rolling devices of a conventional type within a device according to the invention.
  • a device of the type according to the invention to make rolling devices designed according to the invention movable along a workpiece axis, so that the rolling devices can be moved into desired and pre-programmable working positions by means of appropriate drive and control means, for example via programmable NC controls.
  • the program can do more than just that Positioning the rolling devices themselves but also the selection of the tools to be brought into position.
  • a device according to the invention in the form of a crankshaft rolling device with a basic structure, as is already known in the prior art mentioned, is described as an example.
  • This device contains at least one deep rolling device 1, consisting essentially of two arms 6 and 7. These arms 6 and 7 can be connected in a known manner to one another in a known manner via the tabs 23 and the hinge pin 24.
  • a piston-cylinder unit 10 is also arranged in a known manner, which moves the arms 6 and 7 like pliers or scissors.
  • the roller head required in each case is arranged on an arm 6 or 7 in the prior art.
  • joint pins 25 and 26 are provided there, which carry the fork-shaped levers 19 and 20 in an articulated manner.
  • the levers 19 and 20 can be around their Swivel pivot pins 25 and 26 freely, as indicated by arrows 27 and 26 '.
  • a piston-cylinder unit 21 is connected via a piston rod to the lever 19 via a joint 28, while the cylinder of the piston-cylinder unit 21 is supported on the lever 6.
  • the lever 19 In the switching position shown in FIG. 1, the lever 19 is in the angular position 15.
  • known deep-rolling tools 13 and 13 ' are arranged. In the angular position 15 of the lever 19, the deep rolling roller head 13 is in the working position.
  • a support roller head 14 Arranged opposite the deep rolling roller head 13, in a manner known per se, is a support roller head 14 which is arranged on the lever 20.
  • the angular position 17 of the lever 20 holds the support roller head 14 in the working position, so that the transition radii 2 on the main bearing 3 can be rolled.
  • the levers 6 and 7 are moved via the piston-cylinder unit 10 in a manner known per se and thus the deep rolling roller head 13 and the support roller head 14 are brought into contact with the corresponding bearing points of the crankshaft 5.
  • the connecting rod bearing 4 can be rolled in the region of the fillets 2.
  • only a corresponding device has to be arranged.
  • crankshaft 5 For the machining of the crankshaft 5, this can, as shown in FIG. 2, be accommodated between centers and driven centrally, so that the deep rolling device 1 does not need to be suspended via master shafts.
  • crankshaft 5 now arrives as the next workpiece with, for example, modified fillet radii
  • the deep-rolling roller head 13 ' can be matched to this.
  • the piston-cylinder unit 21 is actuated so that its piston rod retracts.
  • the lever 19 is moved from the angular position 15 into the angular position 16.
  • the deep rolling roller head 13 ′ comes into the working position and the crankshaft 5 with the changed radii can be rolled by means of the rolling elements 40.
  • the pivoting movement in the direction of arrow 27 of the lever 19 is of course in no way to the two described in the embodiment Switch positions limited. More than two switching positions can also be provided. Likewise, more than two deep rolling roller heads, each with different rolling elements 40, can be used. But it also makes sense, depending on the application, to provide only a single deep rolling roller head 13, for example when the now possible swiveling movement via the lever 19 is only or preferably to serve to simplify the tool change for the tool 13 or in the event of a break in the rolling elements 40 to simplify the change of the rolling elements through better accessibility. However, the insertion of the workpiece can also be simplified by such a pivoting movement.
  • the support roller head 14 can also be pivoted in the direction of arrow 28, for example by means of the handle 22 from the angular position 17, which represents the working position, into the angular position 18.
  • the locking bolt 29 is removed so that the lever 20 can now be pivoted effortlessly via the handle 22.
  • the locking bolt 29 is then reinserted and then sits in the bore 30 of the arm 7.
  • the support roller head 14 can be replaced effortlessly.
  • a deep rolling device 1 ' accordinging to FIG. 3 is very similar in structure to that Deep rolling device described so far.
  • the arm 7 with the support roller head 14, which is articulated via the lever 20 on the arm 7 via the hinge pin 26, can be constructed exactly as already described for FIG. 1.
  • This lever 7 is in turn articulated by means of the hinge pin 24 and the tab 23 to an arm 6 ', the first ends 8' and 9 of the arms 6 'and 7 being connected to a piston-cylinder unit 10 which the Swivel movement of the arms should cause relative to each other and which generates the necessary rolling force.
  • this has a slide guide 37 on the underside, on which one or more slides 35 can be arranged.
  • the one or more slides 35 are displaceable in the direction of arrow 36.
  • the slides 35 carry deep rolling roller heads 31, 32 and 33, which in turn contain rolling elements 40. Since a plurality of carriages 35 are provided in the exemplary embodiment, the deep rolling roller heads 31 to 33 are connected to one another via tabs 38.
  • the deep rolling roller head 31 is here in the working position 34, while the deep rolling roller heads 32 and 33 are available for a roller head change.
  • the roller head 33 is connected with its associated slide 35 via an arm 39 to the piston-cylinder unit 21 '.
  • An inward and outward movement of the pistons rod of this piston-cylinder unit 21 ' causes a corresponding displacement of the carriage 35 and thus the roller heads 31 to 33 in the direction of the arrow 36.
  • any desired roller head can be brought into the working position 34 or removed from it.
  • the roller head located in the working position can be mechanically locked or held in working position 34 via a position control of the piston of the piston-cylinder unit 21 '.
  • the deep rolling devices described can be used both on deep rolling machines according to the prior art cited at the beginning and can also be used as individual devices.
