Definitions

  • the invention relates to a press with a plurality of press stations for the serial processing of preferably larger sheet metal parts in the press stations, which are arranged along a transport direction.
  • a transfer device is usually provided, with the aid of which the workpieces increasingly deformed in the successive processing stages are transported from the press station to the press station.
  • the parts pass through both cutting and deformation stations, and the outer contour of the workpieces can be changed considerably, particularly in the cutting stations.
  • a device for the step-by-step transporting of workpieces along several stations of a press which contains both cutting and forming stations.
  • a three-axis transfer device which has two pairs of gripper rails, is used to transport the workpieces.
  • the gripper rails of the first pair of gripper rails are arranged at a relatively large lateral distance from one another and serve to transport relatively wide workpieces, for example when they are introduced into a cutting station.
  • the gripper rails which are arranged at a small lateral distance from one another, run below the die of a relevant press station and serve to receive a cut-out workpiece that is passed down through the die.
  • Both those in large lateral spacing of the gripper rails and the closely spaced gripper rails extend over several press stations.
  • the gripper rails perform a cyclical longitudinal movement to transport the workpieces.
  • a drive device is provided for receiving and releasing the workpieces, by means of which the gripper rails of each pair of gripper rails can be moved towards and away from one another.
  • the drive device is designed so that the transverse movement of the gripper rails takes place synchronously in the opening and closing directions.
  • the gripper rails arranged at a greater distance run through a larger path than the gripper rails arranged at a smaller distance.
  • a gear transmission ensures the relationship between the two movements.
  • a transfer unit is provided in a press with a plurality of press stations, the two in a first press area substantially parallel to one another and parallel to the transport direction arranged gripper rails, which are equipped with gripper means.
  • cooperating drive means are provided with these gripper rails, by means of which the gripper rails can be moved towards and away from one another and at a constant distance from one another in a direction perpendicular to the transport direction and finally in the transport direction.
  • the transfer unit also has two transport rails arranged in a second press area, which follow the gripper rails in the transport direction and are arranged parallel to one another at a distance, and second drive means.
  • the transport rails can be moved at a constant distance from one another in a direction perpendicular to the transport direction and in the transport direction, the gripper rails carrying traverses arranged transversely to the transport direction, which are provided with gripper means.
  • the press is provided with a transfer device which contains two transfer systems which operate essentially independently of one another.
  • the first transfer system is formed by the two gripper rails arranged in a first press area, which are arranged essentially parallel to one another and parallel to the transport direction.
  • These gripper rails can be moved by the corresponding drive means both in the longitudinal direction, which corresponds to the actual transport movement, and in the lateral direction, ie towards and away from one another, and in the vertical direction, wherein they are moved at a constant distance perpendicular to the transport direction.
  • the latter movement is usually a lifting and lowering movement that takes place in the vertical direction. This movement serves to lift workpieces out of corresponding matrices or to insert them into them.
  • the lateral movement component is used for opening and closing, the gripping means carried by the gripper rails being brought into engagement with the workpiece when closing and being separated from the workpiece when opening.
  • the transport movement thus takes place with gripper rails approximated to one another, while the return movement takes place with gripper rails separated from one another.
  • This section of the transfer system primarily serves to transport the workpieces through press stations in which the outer contour of the workpiece is still largely similar to the sheet originally introduced into the press. In particular, it is essential that the dimension transverse to the direction of transport, i.e. the width of the workpiece and thus the outer edges of the relevant dies are not too far apart in this area.
  • transport rails are arranged in the second press area, which are connected to one another by cross members.
  • the crossbeams carry gripping means such as suction devices, suction spiders or the like.
  • the transport rails are provided with drive means which can give them both a lifting and lowering movement and a feed movement. The distance between the transport rails does not change during normal operation of the press.
  • the section of the transfer system formed by the transport rails extends through a press area in which matrices, ie sliding tables with a greater width or with a greater lateral distance between the outer edges, are required.
  • matrices or sliding tables are arranged in particular in press areas in which cutting stations are provided or which follow cutting stations. If several workpieces are cut from a sheet of metal, which are parallel to each other by subsequent If the press stations are to be clocked, the required total width of the press can be reduced compared to operation with a pure three-axis transfer.
  • the workpieces are gripped, for example, from above by the gripper means attached to the cross members, so that no space is required for gripper means working from the side or for gripper rails moving sideways.
  • the dies and sliding tables can therefore make full use of the available width in the press in this area.
  • the length available in the transport direction is optimally used in the first press area. Because of the possible lateral access of the gripper means to the workpieces, no longitudinal sections serving as waiting positions for any gripper means between the press stations are required.
  • the transfer unit combined from a three-axis transfer device and a transfer device with crossbeams thus makes it possible to build a very compact press with an overall rectangular layout for a given processing sequence, in which both the width measured transversely to the transport direction and the length measured longitudinally to the transport direction are minimized.
  • the dimensions of the press with the transport device mentioned are therefore compact and therefore inexpensive to manufacture.
  • the drive means are advantageously designed such that the gripper rails and the transport rails can be moved independently of one another. As a result, the return of the three-axis transfer, which is formed by the gripper rails, can take place when the transport rails, which form a two-axis transfer, are in the park position.
  • the gripper rails are driven by two drive units.
  • One is a lifting and closing device that controls the lateral movement of the gripper rails and their lifting and lowering movements.
  • the other is a feed device that moves the gripper rails in the transport direction.
  • This separation into different drive units enables the optimal design of the respective drive device for the given purpose. As a result, the respective movement curves that occur can be optimized for the different directions of movement and the accelerations can thus be minimized.
  • a linear guide can be used to decouple the longitudinal movement of the gripper rails from their lifting and transverse movement, the gripper rail then being connected to the lifting and closing device via a telescopic device.
  • the gripper means carried by the gripper rails can be fastened to separate supports which are detachably fastened to the gripper rails. This makes it easy to exchange the gripper means when changing tools.
  • Coupling means are used for this purpose, which uncouple the crossbeams from the latter when the transport rails move laterally outwards.
  • a drive device provided for the transport movement and a separate drive device can also be provided for the transport rails, which accomplishes the lifting and lowering of the transport rails in accordance with the predetermined transfer curve.
  • the device carrying out the lifting and lowering of the transport rail can be designed as a lifting and closing device be, which can also give the transport rails a lateral movement, by means of which the transport rails can be separated from the trusses.
  • the gripper rails belong to a first transfer device, which is preferably arranged in an upstream region with respect to the transport direction, in which deep-drawing stations or similar forming stations are often arranged.
  • the section of the transfer device containing the transport rails is preferably located downstream in the region of separating or cutting stations.
  • the movement curves traversed by the two transfer devices can each be optimized separately, it being advantageous if the movement sequences are coordinated with one another.
  • the inherently somewhat slower second transport device with the crossbeams is designed for maximum speed if the resulting accuracy is sufficient. The speed can range from 15 to 16 strokes per minute.
  • the first transfer device which has an inherently higher speed potential, can be designed with the three-axis transfer for maximum precision or minimum energy consumption.
  • a variable and versatile press results with regard to the positioning of the workpieces to be transported if the gripping means provided on the crossbars are mounted on the crossbars such that they can be displaced transversely to the transport direction.
  • the gripper means are each connected to an adjusting device, which enables a targeted movement of the gripper means in relation to the crossmember. If, for example, several individual parts have been cut out of a workpiece in a cutting station, these can be brought to the appropriate lateral distance by means of the gripper means and machined in subsequent forming stations at a spatial distance from one another.
  • the press shown in Fig. 1 is a multi-stage transfer press 1 with a total of four successive press stages 3, 5, 7, 9.
  • Each press stage 3, 5, 7, 9 includes a die and an up and down movable not shown Ram, which can be moved via a corresponding drive unit away from the die in question or toward it in a force-actuated manner.
  • the plungers are guided in a machine frame and driven by a drive device which is supported by only schematically indicated columns 11, 12, 13 and by further columns, which are only indicated in FIG. 1 by their layouts 15, 16, 17.
  • the rams and thus the press stages 3, 5, 7, 9 work in unison.
  • a transfer unit 24 which contains a first transfer device 26 and a second transfer device 27, is used for the further transport of workpieces which have been introduced into the multi-stage transfer press 1 by a feed device 22.
  • the first transfer device 26 is arranged upstream with respect to the transport direction denoted by the X direction of the axis cross XYZ, while the second transfer device 27 is arranged downstream with respect to this transport direction.
  • the transfer device 26 thus extends through a first section of the multi-stage transfer press 1 and the second transfer device 27 through a second section.
  • first section of the multi-stage transfer press 1 ie in the Press stages 3 and 5
  • forming processing steps are carried out on the workpieces, such as deep drawing or the like.
  • subsequent second section of the multi-stage transfer press that is to say in the press stages 7 and 9, cutting processes, separation processing steps and, if necessary, further forming steps are carried out.
  • the first transfer device 26, which is upstream in the transport direction X, is designed as a three-axis transfer device and has two gripper rails 31, 32 which are spaced parallel to one another and are moved synchronously with one another.
  • the gripper rails 31, 32 each pass through a transfer curve for transporting the workpieces, in the course of which they are moved both in the X and in the Y and in the Z direction.
  • the movement in the X direction serving as the actual transport movement is given to the gripper rails 31, 32 synchronously by a feed device 34, which is only indicated schematically in FIG. 1.
  • a lock box 36, 37 arranged in front of and behind the base frame 19 of the relevant sliding table is used.
  • the gripper rails 31, 32 are provided with grippers 39 which are arranged on corresponding supports 41, 42. If necessary, these can be separated from the gripper rails 31, 32.
  • each gripper rail 31, 32 is via a corresponding, telescopic linear guide 44, 44a, 45, 45a connected to the respective lock box 36, 37.
  • the transfer device 27 is designed as a sucker cross transfer and has two transport rails 51, 52 which are held parallel and at a distance from one another. At the end, the transport rails 51, 52 are connected to a feed unit 53 and each with telescopic linear guides 54, 54a, 55, 55a with lock boxes 57, 58, which are essentially operated as lifting units.
  • the transport rails 51, 52 are connected to one another by traverses 61, 62, 63, which are spaced apart from one another transversely to the transport direction (X direction) and are detachably held on the transport rails 51, 52 by coupling means (not shown).
  • the feed unit 53 drives the transport rails synchronously in and against the X direction.
  • the traverse 61 is provided with two carriages 65, 66 which can be displaced in the Z direction and each carry vacuum grippers 67, 68.
  • the carriages can be adjusted in the Z direction by means of a drive device 69.
  • the other traverses 62, 63 are identical in construction to the described traverse 61.
  • the carriages, vacuum grippers and drive devices in question are therefore provided with the addition “a” or "b” for the purpose of differentiation without a new description and reference Reference numerals denoted or not explained in further detail.
  • FIGS. 2, 3, 4 and 5 in which the multi-stage transfer press 1 is shown in a highly schematic manner.
  • the lock boxes 37, 57 arranged at the columns 12, 16 represent the separation point between the transfer devices 26, 27.
  • the matrices upstream of this separation point are only indicated schematically and correspond to the sliding table 19 from which they are received , labeled with 19 '.
  • the matrices downstream of the separation point are designated 20 ′ or 20 ′′ corresponding to the sliding table 20 from which they are received and marked by a rectangle that indicates their outer contour.
  • the die 19 ' serves, for example, to remove a drawing edge present on the workpiece designated here W and is relatively narrow. Because of the edge present on the workpiece W, however, it is relatively long in relation to the X direction.
  • the die 20 ' serves, for example, to separate, i.e. Cutting the workpiece W into two workpieces Wa and Wb to be further processed in the die 20 ′′.
  • the matrices 20 'and 20'' have a larger transverse dimension, ie a greater width than the die 19''. However, the length measured in the transport direction (X direction) is less. While the lateral free space released by the die 19 'is claimed by the gripper rails 31, 32 for their gripping and release movement in the Z direction, the transport rails 51, 52 are held at a wide distance from one another and give a maximum lateral space for the dies 20 ', 20''free. However, there is a free space F between the dies 20 ′, 20 ′′, which makes it possible to bring individual traverses 61, 62 into a waiting position during a working stroke of the rams assigned to the respective dies 20 ′, 20 ′′.
  • the transfer device 26 makes maximum use of the space available on the side of the die 19 '
  • the transfer device 27 uses the installation space which is present anyway between the dies 20', 20 '', so that the multi-stage transfer press 1 can be constructed in a space-saving and compact manner, which makes considerable cost savings possible .
  • the grippers 39 of the gripper rails 31, 32 are moved outwards in the Z direction and thus from, starting from an initial position shown in FIG. 2, designated A, in which the workpieces W are stored in the positions shown the workpieces W separately.
  • This position, in which the grippers 39 are or are separated from the workpiece W is denoted by S in the left-hand part of the diagram that characterizes the transfer curve in FIG. 2 and is shown in FIG. 3.
  • the transport rails 51, 52 undergo a slight lifting / lowering movement in the Z direction and a movement counter to the X direction, which brings the crossmember 61 from its initial position A into a parking position denoted by P and shown in FIG. 3.
  • the gripper rails 31, 32 which have been separated from the workpieces W laterally and are not in the press area with their grippers 39, can gradually move to move to a return point designated R in FIG. 2. This movement can be optimized for accuracy or energy.
  • the gripper rails 31, 32 of the transfer device 26 can start a feed movement running in the Z direction starting from the return point R in order to bring the grippers 39 into engagement with the next workpiece W at the point G in the die 19 'is located.
  • the gripper rails 31, 32 are in the position shown in FIG. 5.
  • the traverses 61, 62 begin to move out of their parking position shown in FIG. 4 into a gripping position denoted by G.
  • a slight lifting / lowering movement in the Y direction is superimposed on this movement, which runs essentially counter to the transport direction in the X direction.
  • the vacuum grippers 67, 68 are resting with respect to the crossbeam 61, the vacuum grippers 67A, 68A are moved towards one another in order to be able to pick up the workpiece W lying in the die 20 ′.
  • a transfer unit is provided for transporting the workpieces through the press stations 3, 5, 7, 9 arranged one after the other in the processing sequence.
  • the transfer unit has a first section 26 designed as a three-axis transfer and a second section 27 designed as a cross-beam transfer.
  • the three-axis transfer has a pair of mutually parallel gripper rails with gripper means which can be brought into and out of engagement with the workpieces by a lateral feed movement of the gripper rails. To do this, the gripper rails require a certain amount of lateral space.
  • the cross-beam transfer requires parking positions between individual press stations, in which the cross-beams remain when the press stations are in operation. While there are already free spaces next to the sliding tables in the first press section, the parking positions for the crossbeams can be provided in the second press section because of the shorter dies, without enlarging the press.
  • the intricate combination of the three-axis transfer with the cross-beam transfer enables an adapted, good use of space in the entire press area.
