Definitions
- the invention relates to a press with a transfer device for Sheet metal parts of the type specified in the preamble of claim 1.
- the sheet metal parts are transported by means of such presses a transfer device with two- or three-dimensional movement the holding means for the sheet metal parts, insertion and removal the sheet metal parts by means of feeders.
- DE 33 29 900 A1 describes a transfer device in a transfer press described with two moving in three axes (three-dimensional) Transfer bars that are horizontal and at a parallel distance from each other run.
- the conversion device also has one on one Advance mechanism for generation arranged at the end of the transfer bar a back and forth movement, as well as two clamping mechanisms for the clamping and releasing movement and two lifting mechanisms for lifting and Lower the transfer bar.
- the advancement, tensioning and lifting mechanisms are each controlled by a own DC servo motor driven, the one transfer bar side are assigned, and the longitudinal, transverse and vertical strokes the transfer bars are independent of each other and continuously variable.
- the drive movements are based on a torsion shaft transfer the drive side of the second transfer bar.
- US 4,625,540 A describes a transfer device in one Transfer press of two-dimensional type, with the rails in longitudinal extension the press in front of and behind the tools are lowerable.
- the rails In the rails is a horizontal press extension moveable frame stored.
- the bars are in addition to the movement of the rack in one movement in Press extension movable.
- the drive of the lifting and lowering movement the rails and thus the frame and the drive of the Frame in the horizontal plane and the additional movement the bar is curve controlled and therefore dependent on the Press controlled.
- GB-A-2 243 134 which corresponds to the preamble of claim 1, is a transfer device in a press with up and down movements Ram known for forming sheet metal parts. It is an implementation facility available with holding means for holding and moving the sheet metal parts from processing stage to processing level.
- the transfer movements in the lifting and lowering direction and in the transfer direction are generated by adjusting means, of which adjusting means for movements in and against the transfer direction are arranged on guide rails.
- the latter means of adjustment are not used for the segmented transfer of insertion or removal into or out of the processing stage (tool), and the transfer device does not allow different Number of cycles in the subsequent processing stages or time-shifted downward and upward movements the pestle.
- the transfer device can be expanded with regard to the holding means, so e.g. for double parts. There are both a drive element each Axis and separate drive possible on each drive side.
- the Means of transport can be deflected in the guide bar on each side Toothed belt to which the holding means or are attached.
- the Implementation devices are modular for one after the other staggered arrangement by a multi-stage press, press line or also multi-column press.
- the transfer device can be used as a loading and Tapping device (feeder) can be used. In addition to smaller sizes a higher stiffness is achieved compared to previous feeders.
- the press 1 in Fig. 1 can be a single press or one (Follow) presses 51 to a press system, compact press, hybrid press be an extended forming system.
- the press 1 has a head piece 7 with the press drive for the plunger or 2 (Fig. 2). With 4 are Press stand positioned, which is placed on the press table 6 are and on which the head piece 7 is placed.
- a sliding table 5 movable In the press 1 is a sliding table 5 movable. Over this are the tools interchangeable. Ram 2 and tools are in Fig. 1 for reasons Better visibility of the conversion devices 8.9 not shown.
- the press stands 4 each have a vertically running guide 18, in which, as shown in FIG. 4, a guide carriage 41 can be raised and lowered.
- Each of the conversion devices 8.9 comprises also a guide bar 16, the two left and rear Press stands 4 is assigned and a guide bar 17, the is assigned to the two right and front press stands 4. From therefore the guide bar 16 is behind, the guide bar 17 Tool and plunger 2.
- the guide strips 16, 17 are rigid with the associated guide carriage 41 connected. On each carriage is 41 each attached a rack 24 that is parallel to the vertical Guides 18 is guided.
- the guide strips 16, 17 can be in one piece be and so over the total length of the workpiece movement by the Extend press 1.
- a conversion device 8.9 as Insertion feeder (insertion device) or as removal feeder (removal device) these are the front insertion area or the rear removal area assigned.
- the guide strips 16, 17 can be divided and thus only take up one means of transport 25, 26.
- the guide rails 16, 17 extend over the entire transport path of the sheet metal parts 3 in press 1, when dividing over a partial route.
- Each of the Guide strips 16, 17 have a horizontal longitudinal guide 62 on for guiding holding means 10, 11 over rollers 43.
- the adjustment means, the are positioned with a total of 13.14, servomotors 29.31.33 have the gearbox 30,32,34 and the pulleys 28 around the Deflection pulleys 27, 28 toothed belts 25, 26 or the like Means of transport in a reciprocating, horizontal movement drive.
- the holding means 10, 11 for converting the sheet metal parts 3 in Passage direction 15 through the press 1 can active pliers, passive pliers or as shown, magnet or suction-mounted cross members 10, Be 11.
- the cross members 10, 11 are at both ends of the driver 42 one of the transport means 25, 25 and 26, 26, respectively.
- Figs. 2 and 3 are the same parts as in FIGS. 1 and 4 positioned immediately.
- Fig. 2 shows a support plate 36, which is press-tight is attached and on which a first adjusting means 19 for lifting and Lowering the guide strips 16, 17 and the components connected to them is attached.
- the movement of e.g. trained as a servo motor first adjustment means 19 is horizontal via a gear 21 extending torsion shaft 22 transmitted at both ends engaging in and interacting with the racks 24 Gears 23 are rigidly attached.
- Fig. 3 shows two press-fixed support plates 40 for one each Adjustment means 37, a servo motor, which on the gear 39 each next assigned gear 23 acts.
- the gears 23 or gear 39 are interconnected by means of a torsion shaft 38.
- the gears 30, 32 or the driven ones are also in the same way Deflection rollers 28 in Fig. 1 by a torsion shaft 20 with each other connected.
- the transfer devices 8, 9 in FIG. 1 are arranged one behind the other, so that between the means of transport, toothed belt 25, 26 a Distance is present. 5, this distance is between the mutually facing deflection rollers 27 of the toothed belt 25 and 26.
- the drivers 42 are between the fastening area 63 on the toothed belt 25, 26 and the fastening area 64 of the holding means 10, 11 are selected to be correspondingly long.
- the driver 42 on the toothed belt 25 and the driver 42 on the toothed belt 26 are directed against each other.
- the conversion movement of the sheet metal parts 3 in the direction of passage 15 begins with the removal of a sheet metal part 3 from a removal position 48, which is an unstacking station or an orientation station for the Sheet metal part 3 can be or from a clipboard for the sheet metal part 3, in one lifting motion.
- This lifting movement is done by the first Adjustment means 19.21 and 37.39 generated.
- This is followed by a conversion movement 44 with a final lowering movement into the z.
- the conversion movement 44 is generated by the second adjustment means 13.
- This position 50 can be a processing station Clipboard, also be a conveyor belt.
- the return movements of the Holding means 10, 11 are indicated with 46, 47.
- a multi-column press of the type press 1 and hint press 51 with further (subsequent) presses in Fig. 1, according to Figs. 6 and 7 a previously used Insert feeder by a transfer device 52 in the previously described modular design to be replaced.
- the one with magnets or suction cups equipped truss 53 can be used to bridge larger distances, e.g. trained to insert in the first processing stage 54 extended.
- the conversion devices 55 and 56 are in the previously explained Construction carried out. Due to the overlapping arrangement of the means of transport 25.26 due to the lateral offset of these to each other 5 described gap between the deflection rollers 27 avoided.
- Holding means 57, 58 likewise designed as a suction bar are therefore of different lengths.
- clipboards are positioned for an interim Storage halfway, about half the distance, between processing stages 54.
