Definitions

the invention relates to a transfer device or the like in a transfer press. Forming machine.
Transfer presses, large section presses, press systems are forming machines in which sheet metal parts are formed by process steps such as drawing and punching.
the presses have at least one ram to which a tool or tool set (upper tool) is fastened, which interacts with a tool or tool set (lower tool) in the press table or on a sliding table.
the plungers can be moved up and down via drive means of the press.
the so-called empty stages, clipboards are attached.
the tools or tool sets are changed using sliding tables that can be moved out of the press for this purpose.
Crossbars are movably supported in guides of the transfer rods via an additional drive relative to the transfer rods.
Vacuum cups are attached to the crossbeams and can be adjusted to the length of the sheet metal parts by moving the crossbeams.
the crossbeams with the vacuum cups can be adjusted in areas outside of the ram and tools.
the transfer rods can be raised and lowered by lifting means, not shown or explained.
the parts of the transfer device to be moved should be low-mass and enable high accelerations in a shortened transfer movement and in the return of the holding means which grip the sheet metal parts.
the transfer device is intended to carry out lifting and lowering movements for removing and depositing the sheet metal parts from or into the tools.
the low-mass structure is an advantage here.
the drive means and the movement transmitting and deflecting means of the transfer device are assigned to the area (head area) of the press or the presses, in that the drive means for the plunger (s) are also accommodated.
the transfer device can be retrofitted in both press lines and compact presses. Also essential to the invention are the short transfer movements of the carriages and their temporary waiting position outside the processing stages during the forming phases.
the transfer device according to the invention can be used in novel hybrid press systems with intermediate shelves set up between two processing stages (empty stages), since the carriages can carry out different movements in pairs if the drive is designed accordingly.
a hybrid press system is shown with a head press 1, which can be a drawing press, and with further presses 2, of which at least one further press can contain an additional drawing stage.
the head pieces 7 of the individual presses 1, 2 are supported on stands 8, 11 on press tables 8.
With 10 connecting rods are indicated, which, for example, starting from a main shaft 39 via a crankshaft drive, drive the tappets 6 of the presses 1, 2 in an up and down movement.
the main shaft 39 is rotated by one or more motors via a clutch brake unit 38.
Tools or tool sets 14, 15 can be moved into the processing stages of the presses 1, 2 and thus exchanged by means of sliding tables 13, the tool or tool set 15 (lower tool part) remaining on the respective sliding table 13 for the forming operation of the presses; the tool or the tool set 14 (upper part of the tool) moves with the movement of the plunger 6.
a drawing device 9 is indicated for the head press 1.
the sheets 33 fed from a feed device 3, for example the head press 1, are moved by means of a transfer device 5 from processing stage to processing stage and fed to a removal station 4.
33 ' is shown in FIG. 2 to different sizes, to be promoted and to bear sheet metal parts referenced.
With 32 the direction and the plane of the sheet metal parts transport is indicated.
intermediate shelves 17 are set up for storing the sheet metal parts 33.
Supports 35 are provided on the sliding tables 13 for receiving crossbeams 34 of the transfer device 5 to be described in more detail below.
the conversion device 5 initially has two running rails 18, one of which runs behind the plungers 6 with the tool upper parts 14, viewed in FIG. 1, the second running rail in front of the plungers 6 with the tool upper parts 14 in the longitudinal direction of the shown Hybrid press system is arranged extending.
the running rails 18 can be raised and lowered by means of adjusting means such as air cylinders or the like or, as shown, by means of deflecting gears 19 (double arrow 20).
the deflecting gear 19 are still in detail to FIGS. 5 and 6.
the deflection gear 19 of the rear stator side and that of the front stator side are each connected by a lifting linkage 21 with one cam follower lever 46 per stator side of a cam disk arrangement positioned overall at 41 in articulation points 22.
carriages 23 to 31 are located on each of the rails 18.
the carriages 23, 25, 27, 29 and 31 are by a transport linkage 37 with each other and with a cam follower 47 connected.
the carriages 24, 26, 28 and 30 are connected to one another and to a cam follower lever 48 by a transport linkage 36.
the carriages 23 to 31 located opposite one another on the spaced running rails 18 are connected to one another by cross members 34.
the transport rods 36, 37 can optionally be arranged on both sides of the running rails 18, FIG. 2, or on one side to the running rails.
the cam disk arrangement 41 comprises, as shown in FIGS. 2 and 3 can be seen in more detail, a camshaft shaft 42.
the camshaft shaft 42 is rotated by the main shaft 39 via a deflection or conversion gear. This means known in metal forming machines are not ge has been shown.
a cam 44 for the movement of each of the cam follower levers 46, a cam 45 for the movement of each of the cam follower levers 47 and a cam 43 for the movement of each of the cam follower levers 48 are arranged in a rotationally fixed manner on each stator side.
the cam disks 44, 43, 45 can be double cam disks for generating a forced run in the movements of lifting and lowering the running rails 18 and the transfer movements of the carriages 23 to 31.
each of the lifting rods 21 in its starting position can be changed by a lowering movement, 94 in FIG. 4, of an actuating drive in order to achieve a further lowered position for the running rails 18, which the cam disks 44 cannot predetermine.
This lowered position is necessary for the storage of the crossbeams 34 on the supports 35 of the sliding tables 13 when changing tools and changing the holding means 40.
each actuator has a servomotor 51 which drives a spindle 52. The rotational movement of the spindle 52 is transmitted to a second spindle 49 via a gear pair 53.
a movement thread (nut) is introduced into the tab 54, which interacts with the spindle 49 and thus causes a change in the length of the lifting rod 21 when the spindle 49 rotates.
the cam disks 45, 43 for the movement of the carriages 23 to 31 are designed in their cam tracks tapped by the cam follower levers 47, 48 in such a way that the first carriage 23 and each next carriage 25, 27, 29, 31 as shown in FIG. 4 have a transfer movement 82 executed from a processing stage 86 into an empty stage 88 with the intermediate storage 17 and a return movement 84 into the processing stage 86 interrupted in an intermediate position 89 between the processing stage 86 and the empty stage 88 for the time of the forming.
the processing stages are characterized by the tools 14, 15.
the Vertically guided parts of the movement on the curves 82, 83, 84, 85 shown in FIG. 4 are brought about by means of the cam discs 44 which are moved synchronously with the cam discs 43, 45.
the section shown in FIG. 5, and partly also the section shown in FIG. 6, shows the area of one of the stands 12 with a deflecting gear 19.
the lifting linkage 21 in FIG. 5 runs perpendicular to the plane of the drawing.
the movement of the lifting rod 21 is transmitted to a second spur gear 58 by means of teeth and engagement with a spur gear 56 and a rotary shaft 57.
the second spur gear 58 interacts with a rack 59.
the end regions of the toothed rack 59 are firmly connected to an upper flange bushing 61 and a lower flange bushing 62.
the upper collar bushing 61 forms a running surface 65 for a lifting tube 64.
the upper collar bushing 61 also interacts with a cover plate 63 which is screwed onto an upper collar of the lifting tube 64.
This connection enables the lifting tube 64 to be rotated.
the rotation of the lifting tube 64 is brought about by an adjusting means 76, for example a pressure cylinder, which is attached to the frame via a bearing block 77.
the bearing block 77 enables the adjusting means 76 to pivot.
the adjusting means 76 is articulated at 78 on an annular bushing 75.
the ring bushing 75 engages e.g. Via guide bolts in longitudinal grooves 90 of the lifting tube 64 in order to enable the lifting and lowering movement 20 of the lifting tube 64 required for the running rails 18 on the one hand and to cause the lifting tube 64 to rotate on the other hand.
the lifting tube 64 carries on the lower end part a flange 66 with a flange bushing 67.
the flange bushing 67 is surrounded by a bearing bushing 73 and a support bushing 72.
the support bushing 72 is held in a carrier 71 by means of screw connection 74.
a collar bushing 68 is placed on the lower end of the support bushing 72.
a screw 69 is passed through the collar bushing 68 in order to fasten the carrier 71 to the lifting tube 64.
the running rail 18 is rigidly connected to the carrier 71.
the running rail 18 has two rails or pairs of rails 79, on which rollers 80 of the carriages 23 to 31, here the rollers 80 of the carriage 25, roll.
the transport linkage connected to the housing 81 of the carriage 25 is numbered 37. Due to the rotary movement of the lifting tube 64 by means of adjusting means 76, one is Adjustment of the rails 18 from the inside to the outside, arrow 91, for example for uncoupling the cross members 34 from the carriages 25 or from the outside inwards, arrow 92, accordingly for coupling.
Fig. 6 also shows the position 64 'by means of actuating means 76' for the operating position and 64 ⁇ for the uncoupling position or coupling position for the cross members 34.
With 93 coupling areas or couplings are indicated for releasing the cross struts 34 from the carriage, here the carriages 24, 25 or for coupling to them as a result of a movement of the running rails 18 in one of the directions of the arrows 91, 92.
the rails 79 are located on the running rails 18 in the center of the lifting tube 64.
