Definitions

  • the invention relates to a multi-station press with a plurality of press stations arranged one behind the other in accordance with a processing sequence.
  • Multi-station presses which can be set up both as a single machine and as a system of presses that are directly linked to one another, are often linked to one another via a transfer system, particularly if they work in a predetermined work cycle, which transports workpieces from one press station to the next press station.
  • the press stations are equipped with tools that are set up for the type of workpiece to be machined.
  • the transfer system also provides gripper means for the special workpiece to be machined or transported.
  • the multi-station press is to be set up to process a special workpiece or to be converted from one workpiece to another, the workpiece-specific parts of the press stations and to replace the transfer system. This should be done as quickly and automatically as possible.
  • a transport device for larger workpieces in a step press has a plurality of press stations which are arranged along a transport direction and are spaced apart from one another and in which dies or lower tools provided for receiving the workpieces are interchangeably arranged on sliding tables.
  • the sliding tables Above the sliding tables, vertically up and down movable rams are provided, which are driven in unison. Each ram is provided with an upper tool and defines a press station with the lower tool arranged on the sliding table.
  • a cross-beam transfer device is provided for workpiece transport between the press stations, which has two mutually parallel transport rails. The transport rails run on both sides of the press stations over the entire length of the step press and are connected to each other by crossbeams.
  • the cross members are detachably connected to the transport rails via coupling devices.
  • So-called locking pins are arranged between the press stations, each of which is connected in pairs to a sliding table and serves to accommodate cross members to be replaced.
  • the crossbeams are placed on the locking pins and moved out of the press with the sliding tables.
  • a press line with individual presses is known, in which the workpiece is transported by gripper rails.
  • the presses are equipped with sliding tables that can be extended and retracted across the direction of transport of the parts by the press stands of the press.
  • the workpieces used to machine the workpieces are exchanged with the respective sliding table.
  • the gripper rails provided for transfer have parts-related gripper rail parts which are each set up for the transport of the special part to be transported. In order to make it possible to change these gripper rail parts, they are each divided into three parts and releasably connected to the gripper rail.
  • the gripper rail parts are provided with the grippers which are to be brought into engagement with the respective workpiece, while the continuous sections of the gripper rails only serve as carriers for the gripper rail parts.
  • the gripper rail parts are each formed by a central part and two adjacent outer parts.
  • the outer parts are telescopically displaceable with respect to the respective central part, the same piston-cylinder units being provided for driving the same.
  • the outer parts are adjusted in the direction of the central part by means of the piston-cylinder units, after which the gripper rail parts forming a unit are placed on a corresponding receptacle of the sliding table and moved out of the press.
  • a transfer press system with several successive press stations is known, which are linked to one another via a cross-beam transfer device.
  • the crossbeam transfer device has two synchronously driven transport rails which are held parallel to one another and between which crossbeams which extend transversely to the transport direction are suspended.
  • the cross members are connected to the transport rails via coupling means and, if necessary, can be detached from them.
  • a sliding table is provided in each press station, by means of which the forming tools can be moved laterally out of the press area.
  • Each sliding table is provided with a receiving device for cross beams released from the transport rods, which is arranged in an intermediate space defined with the adjacent sliding table.
  • This holding device contains two telescopic cylinders which can be pivoted parallel to the sliding table and adjusted in height by means of a lever parallelogram.
  • the receiving device removes the crossbars from the transport rails and folds the crossbars against the tools lying on the sliding table in order to achieve a compact arrangement of the tools to be replaced.
  • This type of changing the gripper means and the tools requires a transfer device with cross members, in which there are spaces between the sliding tables.
  • DE 43 09 643 A1 shows a transfer device for the workpiece transport, which is designed as a three-axis transfer.
  • the transfer device is provided on a press with a plurality of press stations and has two transport rails which extend at a distance parallel and over the entire length of the press. These are moved synchronously in and against the direction of transport and, if necessary, via appropriate lifting devices raised or lowered.
  • the transport rails can be moved towards and away from each other.
  • Carrier rails are carried by the transport rails and are provided with gripping devices for the workpieces.
  • Storage supports are provided on each sliding table to accommodate support rails.
  • support rails located in the stand area are moved out of the stand area by means of the transport rails and into the corresponding storage position at the sliding tables and set down in alignment with one another. In this position, the carrier rails with the sliding tables and the tools placed on them can be moved out of the side of the press.
  • the multi-station press which can be a single machine or a series of several presses linked by the transfer device, is provided with sliding tables that can be moved out of the side of the press and allow a quick tool change.
  • the transfer device has two mutually parallel transport rails on which spaced apart carrier means are carried, which in turn are provided with gripping means for the workpieces.
  • the carrier means can be detached from the transport rails, with receiving means for receiving the carrier rails being arranged on the sliding tables. While the carrier means are arranged at a distance from one another on the transport rails, the receiving means of the sliding tables are designed in such a way that the carrier means can be deposited close to one another, whereby they are not in alignment with one another.
  • Two carrier means that are adjacent to one another on the transport rail undergo a longitudinal stroke during their transfer movement which corresponds to their own length plus the distance to the next adjacent carrier means.
  • Both carrier means can be accommodated on the sliding table in an area whose longitudinal extent measured in the transport direction does not exceed the stroke length and is preferably at most as long as a single carrier means. This can be achieved in particular by overlapping arrangement of the carrier means, for example by stacking them one above the other. Such accommodation of the carrier means enables additional carrier means to be accommodated, which are required in particular if intermediate shelves are located between the sliding tables are arranged.
  • Each transport rail then carries two carriers per sliding table.
  • a sliding table can accommodate, for example, two carrier means arranged one above the other, which do not protrude beyond it. It can therefore easily be moved out of the side of the press area, even if the available passage is restricted by adjacent press stands.
  • a particularly space-saving arrangement of the carrier means on the sliding tables results if the carrier means are held parallel to one another, next to one another or one above the other. If the carrier means are each of a low height, it is ensured that the height adjustability of the transport rail, which is given in any case, is sufficient to place the carrier means on the receiving means. This is preferably done without drive means being provided on the carrier means, ie the carrier means are designed to be purely passive, which keeps their weight comparatively low.
  • a locking device acting between them which serves to lock the gripper means during normal operation of the transfer device, i.e. for workpiece transfer, to be coupled to the transport rails in a stationary manner.
  • the locking device goes into the release position so that the transport rail can detach and separate from the carrier means by a suitable longitudinal movement.
  • the receiving device which can also be rigid, for example, is preferably pivotally mounted on the sliding table. This makes it possible to pivot the receiving device laterally after the transfer of the carrier means, so that the gripper means can be moved out of the tool area and the carrier means out of the range of motion of the transport rail.
  • the transfer unit formed by the transport rails of the drive unit and the gripper means is preferably designed as a three-axis transfer, in which the transport rails are arranged parallel to one another and parallel to the transport direction and in the transport direction, i.e. can be moved horizontally, vertically and towards and away from each other.
  • a three-axis transfer the transfer of the carrier means held by the transport rails to the corresponding receiving means on the sliding tables is possible in a particularly simple manner using the three-axis transfer for guiding and hanging the carrier means into the receiving means without the aid of additional drive units.
  • the first of the first is transported by means of a transport rail
  • Carrier means to be received in a lateral laying movement are inserted into the holding device, after which the transport rail is preferably separated from the carrier means in a combined feed / lowering movement.
  • the transport rail then brings the further carrier means to be connected to the holding device and places it on it.
  • the carrier means can be held close together and thus very space-saving on the sliding table.
  • a multi-station press 1 is shown in detail, which has five press stations 11, 12, 13, 14, 15 arranged one behind the other along a transport direction T.
  • the multi-station press 1 is only shown in sections and its machine frame is indicated by means of press stands 17, which are set up in a row on both sides of the workpiece transport path determined by the transport direction T.
  • the press stands 17 are additionally identified with a letter a to f, the press stands 17d, 17e, 17f arranged to the right of the transport path being indicated only by their floor plans.
  • the machine frame illustrated by the press stand 17 carries, among other things, rams which can be moved up and down in synchronism, not shown, of which each press station 11, 12, 13, 14, 15 is assigned one.
  • Such a ram 19 is indicated, for example, in FIG. 3 for the press station 11.
  • the press stations 11, 12, 13, 14, 15 are each arranged in areas of the transport path T in which there are no press stands 17.
  • the press station 11 is arranged between the press stands 17a, 17b, 17d, 17e, while the press stations 12, 13 are arranged between the press stands 17b, 17c, 17e, 17f.
  • the press station 11 has a sliding table 21 which is mounted in a stationary manner and is designed to receive a lower tool 22 arranged below the ram 19.
  • An upper tool 23 is suspended from the plunger 19 moving towards and away from the lower tool 22.
  • coupling means 25 are used, which can be released if necessary.
  • the lower tools of the press stations 12, 13 are arranged on a common sliding table 31 and the lower tools of the press stations 14, 15 on a sliding table 32 (FIG. 1).
  • the sliding tables 21, 31, 32 permit lateral movement out of the press area in order, for example, to be able to replace the lower tool 22 connected to the sliding table and the upper tool 23 placed thereon.
  • a transfer device 35 which is designed as a three-axis transfer, is provided for transporting workpieces along the transport direction T through all press stations 11, 12, 13, 14, 15.
  • the transfer device has a pair of transport rails 41, 42 each extending near the stand over the entire length of the multi-station press 1, which are arranged parallel to the transport direction T.
  • the transport rails 41, 42 are arranged parallel to one another and can be moved via a drive device 45 both in the X direction which corresponds to the transport direction T and in the vertical direction and transversely to the transport direction T.
  • the vertical is referred to as the Y direction and the transverse direction as the Z direction.
  • the transport device 45 contains for the transport rails 41, 42 a linear drive 47 connected at the end to the transport rail 41, 42, which can be controlled separately and can impart a longitudinal movement in and against the X direction to the transport rails, regardless of their stroke position or their distance from one another .
  • the transport device 45 also includes drive units 49a, 49b, which are connected to the transport rails 41, 42 via linear guides.
  • the drive units 49a, 49b are designed as so-called lock boxes and adjust the distance between the transport rails 41, 42 (Z direction) and their height (Y direction).
  • the lock boxes 49a, 49b are in the Stand area arranged where no sliding tables are provided anyway. Intermediate storage positions for the workpieces are provided above the locking boxes. This also applies to the space between the press stations 11 and 12, a workpiece storage position is also provided here.
  • the transport rails 41, 42 are detachably connected to support rails 51 which are provided with grippers 53 which extend away from the transport rail 41, 42.
  • the grippers 53 extend essentially along the Z direction and can be brought into and out of engagement by a targeted lateral movement of the respective transport rail 41, 42 with the workpiece lying on the respective lower tool, for example the lower tool 22 (FIG. 3) will.
  • the number of carrier rails 51 on the transport rail 41 exceeds the number of press stations 11, 12, 13, 14, 15. The same applies to the transport rail 42.
  • the total length of the carrier rails 51 thus exceeds the width of the between the stands 71a, 17b, 17c existing passages.
  • the carrier rails 51 are flat, stiffened carrier bodies lying on the transport rails 41, 42.
  • the flat bottom 55 of the carrier rail 51 lies on the top side of the carrier rail 41 and overlaps the flanks of the transport rail 41 with its side edges 56, 57.
  • the side edges 56, 57 each carry an inner groove 59, 60, at least at the end, into which a corresponding, fixed web 61 connected to the transport rail 41 can engage.
  • the carrier rail 51 is provided with a locking device 63, which the carrier rail 51 by means of a Locking bolt 64 locked in place on the transport rail 41.

  • Each sliding table is provided on its two sides with such a receiving device 69, only the side of the press station 11 lying to the right, as seen against the transport direction T, is shown in FIG. 3 because of the symmetry of the multi-station press 1 with respect to a longitudinal and vertical plane of symmetry 70 .
  • the receiving device 69 has two pivoting levers 72a, 72b which are arranged parallel to one another at a distance and can be pivoted synchronously with one another into a first storage position shown in FIG. 3 and into a second receiving position shown in FIG. 4 by means of a pneumatic pivoting device 73.
