Definitions
- the invention relates to a press system according to the preamble of claims 1 and 2.
- Sheet metal parts are processed in several processing steps. Originally, single presses, e.g. so-called body presses used. As a further development to press lines, processing was initially carried out with manual handling of the sheet metal parts; later with partially mechanized, then with fully automated conveying of the sheets.
- Multi-column transfer presses meet the demand for high flexibility, high output and short changeover times.
- the eight processing stages required to manufacture sheet metal parts in automotive engineering are distributed in one, two or three rams in the multi-column transfer presses.
- the sheet metal parts there are tool center distances of 2,500 mm and beyond, and the sheet metal parts and the means for converting the sheet metal parts in the processing steps must be accelerated to achieve large numbers of pieces for the transfer movements.
- the press system shows a new development direction according to the overall characteristics of claims 1 or 2.
- Such a hybrid press system uses advantageous peculiarities of both the press line and the multi-column transfer press.
- DE 12 71 067 C which discloses a press line
- DE 23 59 912 C2 which discloses a multi-column transfer press, are therefore described below.
- the press line of the first-mentioned publication consists of a multi-acting drawing press operated as a continuous press as a head press with a transport system for the sheet metal parts controlled by the head press through the press line.
- the drawing press is equipped with a bottom ram and bottom plate ram.
- the transport system for the sheet metal parts has a gripper rail system that extends through the entire press line and can be moved in three axes for opening-closing, lifting-lowering and for transfer and back.
- Each press is an individual machine.
- gripper rails guided through the press line only makes sense if the press rams of the individual presses also permit a synchronous transfer movement of the sheet metal parts. If the press line has to be fully synchronized, complex synchronization means must be used. Although the installation of the individual presses has already led to a reduced space requirement due to the omission of the turning device and consequently a smaller press spacing, on the one hand the small space requirement of multi-column transfer presses cannot be achieved; a comparatively large press foundation (foundation) is furthermore required; on the other hand, the transfer step of the gripper rail system is also a relatively further one. The large mass of the transporting gripper rail system requires large driving forces with high acceleration values.
- the second document teaches a transfer press with several successive processing stations.
- the transfer press is a multi-column transfer press with a head piece supported by a stand, a press table and rams, which can be raised and lowered by a common drive. Tools or tool sets are assigned to the plungers.
- In the area of the press stands there are processing-free steps, so-called empty steps, in which, in another version, clipboards are arranged.
- Two gripper rails are driven in the three axes, starting from the main press drive or a secondary drive, via cam controls. Tools or tool sets and sections of the gripper rails can be exchanged by means of the transfer press or sliding tables which can be moved out of this.
- the forming and / or shear forces in the individual processing stages are different.
- the one-sided loading of the rams as well as the ram, table and tool deflections have an unfavorable effect on the machining and the initial part.
- each processing stage and on the other hand the processing stages of each of the rams must be secured as a whole.
- the transfer press In the event of excessive pressure increases in individual processing stages and in the individual connecting rods, the transfer press must switch off, and it is therefore very expensive to secure the tools and the transfer press.
- the tools or tool sets cannot be set separately and are therefore ready for machining set values.
- Changing the setting of a tool generally changes all tools.
- the masses of the gripper rails are to be accelerated so that the output of the transfer press is low, if only because of the large center-to-center distance of the tools and accordingly the large movement of the sheet metal parts per ram stroke.
- High acceleration values, and here the accelerations of large masses lead to vibrations in all parts of the press.
- the accuracy in the transfer and reshaping of the workpieces is impaired.
- the transfer movement of the sheet metal parts also corresponds to the center distance of the tools in transfer presses.
- the hybrid press system according to the invention takes up a significantly smaller total footprint.
- the transport routes of the sheet metal parts are significantly reduced overall.
- the number of strokes, the output and the press system can be increased.
- the press system forms a self-contained system without the processing steps influencing each other through the forming processes.
- the central control of all systems such as pressure consumers, the movement sequences, the tool change and the like is advantageous here.
- 1A shows a press line with a head press 1 and further follow-up presses 2.
- the sheet metal part fed from a feed device 3 to the head press 1 is held in this by a sheet metal holder ram in a drawing tool and formed by a further ram.
- the movements of the tappets for holding and reshaping take place from top to bottom.
- At least one turning device 6 is therefore required for the further processing of the sheet metal parts in the subsequent presses.
- the sheet metal parts are transported through the press line to the removal device 4 by means of feeder 5.
- the stands of the presses 1, 2 are indicated by 9.
- FIG. 1C shows a combined press system with a double-acting drawing press 1, a turning device 6 and a three-column transfer press with the stands 9 and a device 8 for transferring the workpieces through the processing stages of the transfer press.
- the tool sets from e.g. Two processing stages can be exchanged by means of sliding tables 11.
- the four-column transfer press shown in FIG. 1D has, with the double-acting head press 1, a drawing stage 10 working from the bottom up and a device 8 for transferring the workpieces which is guided through the transfer press.
- the head press 1 is a single-acting press with a pulling device 7 integrated in the press table.
- Fig. 1 F shows a simplified front view and top view of a hybrid press system according to the invention compared to the previous development stages, as will be explained in more detail below with reference to FIGS. 2 to 5.
- Essential and new elements of the invention can already be seen from this schematic illustration.
- a clipboard 12 is arranged between each processing stage.
- Each machining stage can contain both a tool for a sheet metal part to be machined or several tools for several sheet metal parts to be machined simultaneously in the machining stage.
- the device 13 for transferring the workpieces is oriented above the sheet metal part transport plane - above the intermediate shelves 12.
- the head press 1 is, for example, a drawing press with a drawing device 7.
- the drawing press 1 has four stands. The left pair of stands is positioned at 18 and the right pair of stands at 16.
- the downstream presses 2 downstream of the drawing press 1 are equipped with further processing sequences for processing the sheet metal parts 39. The processing may also include re-drawing stages.
- the follow presses 2 also have four stands 16, 17. The stands 16, 17, 18 located at the front have not been shown overall.
- the presses 1, 2 are set up side by side with only a slight distance between the supporting areas of the stands 16, 17.
- the head pieces 21 of the presses 1, 2 are placed on the supporting, supporting areas of the stands 18, 16 and 17, 16 by means of fitting pieces 22 and held by tension anchors 46, Fig. 3, 4, 5.
- Each press 1 has a plunger 26 which can be moved vertically via connecting rods 25.
- the connecting rods 25 engage the plunger 26 at diagonally spaced pressure points 27.
- the connecting rods 25 are curve-driven, or as shown in FIG. 4, crankshaft-driven.
- the drive takes place via a shaft 23 which extends over the length of the hybrid press system and which is rotated by a main motor 45, in FIG.
- Each press 1, 2 is assigned a press table 15, by means of which the stands 18, 16 or 17, 16 or their supporting areas are supported on supports 19. Fitting pieces 22 are also inserted between the press tables 15 and the stands 16 to 18, in order to avoid lateral displacements here as well. The head pieces 21 and the press tables 15 are also placed at a small distance, gap 47, from one another in order to avoid mutual interference.
- the supports 19 common to the uprights 16 to 18 are set up on support surfaces 20 of the foundation 14.
- a slide table 11 is assigned to each ram 26, via which the individual tools 28, 29 can be exchanged.
- An intermediate shelf 12 is arranged between each two presses 1, 2 and 2, 2 with the machining stages characterized by the tools 28, 29.
- the clipboards 12 are e.g. centered on the center distances of the tools 28, 29 and between the stands 16, 17 a, so as to halve the movement of the sheet metal parts 39 per ram stroke.
- a device for transfer is provided, which is generally positioned at 13 and whose essential elements are located above the sheet metal part transport plane 35.
- the transfer device 13 here consists of two running rails 36, which can extend from the feed device 3 to the removal device 4 through the length of the hybrid press system, a first running rail 36 when looking at FIG. 2 behind the plungers 26 and Tool upper parts 28 and a second running rail 36 in front of the plungers 26 and the tool upper parts 28 can be raised and lowered on the presses 1, 2.
- the lifting and lowering movements of the running rails 36 are achieved via lifting devices 40 which are attached to stands 16 or 17 of the presses 1, 2 and e.g.
- Carriages 37 can be moved in the longitudinal direction of the running rails 36 on each of the running rails 36. Opposing carriages 37 are connected to one another by suction bridges 42, as can be seen in more detail in FIG. 3.
- Fig. 3 corresponds to the representation of a horizontal section through the hybrid press system above the sheet metal part transport plane indicated in Fig. 2 with 35.
- Sheets of different sizes (and thickness) are shown in the feed device 3. With 39 is a large starting sheet, with 39 'two smaller starting sheets are indicated. Accordingly, one or two tools for each processing stage must then be introduced into the hybrid press system. For this purpose, a sliding table 11 is pushed over rails in each press 1, 2. The tools attached to these and replaceable or replaceable when setting up the hybrid press system for new workpieces have not been shown. Each plunger 26 is assigned a tool or two tools from the upper tool part 28 and lower tool part 29. While the sliding tables 11 are to be moved out of the presses 1, 2 of the hybrid press system on one side (upwards in the drawing), tools can be inserted from the other side of the hybrid press system via the sliding tables 11 shown in FIG. 3 below .
- the multi-part structure of the stands 16, 17 can be seen from the cut surface and the different hatching directions in the stands 16, 17.
- Multi-part design refers to the load-bearing, supporting areas, but not to cladding parts.
- the distance between the stands 16, 17, or their load-bearing, supporting areas, and the distance between the head pieces 21 and the press tables 15 (FIG. 1), column 47, is such that the individual presses 1, 2 influence one another is excluded.
- the invention provides, without deviating from the idea of the invention, to use a stand 16, 17 or a pair of stands — front and rear arrangement — for two presses placed against one another.
- a one-column arrangement is also given if within a two head pieces 21 of adjacent presses 1, 2 or 2, 2 supporting stands 16, 17 two clamping anchors 46 and two, each supporting an adjacent head piece 21, areas in the manner of sleeves with central or one, then eccentric clamping anchors 46 are present.
- Such arrangements lead to a significant reduction, apart from a negligible size, in the mutual influence of adjacent processing stages.
- tensioning anchors 46 and supporting, supporting areas one sometimes speaks of two-column arrangements.
- FIGS. 2 and 3 are based on head pieces 21 and press tables 15 in the number of individual presses of the entire hybrid press system, but without wishing to restrict the idea of the invention thereto.
- intermediate shelves 12 can be seen with the sheet metal part receptacles 44.
- the upward facing sheet metal part receptacles 44 for supporting the sheet metal parts 39 from below can be adjusted automatically in height, to the size, shape and inclined position of the sheet metal parts 39 by means of adjusting means.
- Setting means, gears and adjusting rods have not been shown in detail, since these means and their installation in the clipboards 12 are easily conceivable.
- the carriages 37 can, as shown in FIG. 3, carry out different movements by means of the transport linkage 38 with an appropriate design of the movement of the cam follower lever 33, in order to on the one hand in conjunction with the lifting and lowering movements of the running rails 36 sheet metal parts 39 out of the tools 29 in to transport the intermediate shelves 12 and, at the same time, sheet metal parts 39 from the intermediate shelves 12 into the following tools 29 and, on the other hand, to remain in the spaces between the tool or ram of a press and the intermediate shelf 12 during the forming phase.
- the first, third, fifth and each but one carriage after the other 37 each have a transport linkage 38, which here lies between the rails 36, and the second, fourth and each one after that Carriage 37 movable over the external transport linkage 38.
- Each transport linkage 38 is placed via a cam follower lever 33 on one of the control cams 48 moved by the shaft 23.
- the suction bridges 42 can be placed on support members 43 on the sliding tables 11 by means of an additional lowering movement of the running rails 36 and can then be uncoupled from the running carriages 37 in order to exchange them with the tools 28, 29 at the same time.
- a motor 45 is fixed in the frame of the drawing press 1 and rotates the shaft 23 by means of a V-belt and flywheel mass via a clutch / brake unit 24. From this shaft 23, the movements of the ram 26 of the presses 1, 2, the lifting and lowering movements of the rails 36 and the Trans fer movements of the carriage 37 tapped so as to achieve synchronism of movements.
- the adjustment movements of the sheet metal part receptacles 44 are indicated by arrows.
- the reference numbers 13 refer to the conversion device for the sheet metal parts 39, with the lifting linkage 41 for the running rails 36, the carriage 37 and the suction bar 42 with indicated, for example, vacuum holding means, suction cups.
- tension anchors are numbered between the head piece 21 and the press table 15. The further reference numbers serve as orientation when comparing with FIGS. 2 and 3.
- Fig. 5 is used for better visibility of the stand areas or support areas between two presses, e.g. between the presses 1 and 2.
- the head pieces, numbered 21, are placed on stands 16 and 17 by means of the fitting pieces 22.
- the stands 16, 17 are placed on the press tables 15 by means of further adapters 22.
- Each individual press 1, 2 is held over the tension anchor 46.
- the press tables 15 are set up above the supports 19.
- the head pieces 21 of adjacent presses 1, 2 or 2, 2 can also be placed on a then common stand 16 or 17 or on a single, load-bearing region of a stand 16, 17.
- the stands 16, 17 can be set up directly via a support 19.
