Description

The invention relates to a method for the production of molded parts in one of a plurality of series-arranged single presses of a press line with the features of the preamble of claims 1 or 2 and an apparatus for performing the method according to the preamble of claims 16 or 17.

State of the art

There are press lines and transfer press lines are known in which individual forming tools a tool set for single and multiple parts can be used alternately in the individual presses. If, instead of large-scale tools, medium to small tools for single parts are used, on the one hand the tool room and on the other hand the installed force of the press is under-utilized. These reserves can be used in the transition to medium to small multiples, with double or quadruple parts primarily a group of similar moldings, such as moldings with the same Umformparametern in a right and a left version are used. The disadvantage is on the one hand in the limited flexibility of the fixed ram motion sequence and on the other hand in the increased tooling adjustments in the possible production of different multiple parts, in which in particular the application is limited by the less favorable molding.

In the DE 10 2004 009 256 A1 there is described a mechanical multi-servo press in which one or more servomotors respectively act on the crank mechanism operatively associated with each of the two pressure points and enable a flexible ram motion profile on the common ram.

The DE 10 2005 040 762 A1 discloses a press line with a flywheel-driven head press and preferably with flywheel-free servo-electric follower presses, in which operational deviations in the desired speed profile of the head press by a host computer and operatively connected to the head press Leitwellengeber be compensated dynamically in the control of the press line. A use of this press line for the parallel production of multiple moldings with individual ram motion profile of adjacent tools per press is not provided.

All three above-mentioned disclosures is also common that in the case of the use of multiple tools on the common plunger mutual interference of the adjacent tools can occur with each other.

After DE 10 2006 019 207 A1 a drive system of a multi-ram forming press is known in which a plurality of rams in a press independently of each other by a servomotor as the main axis of movement are controllable and each ram, if necessary, separately controllable pillows in the table and ram as Nebenbewegungsachsen be assigned. Since each plunger within the multi-stage tool set is associated with a tool level, the motion profiles can be tailored to the respective tool level individually without significant mutual interference. A use of this multi-ram forming press for parallel production of multiple moldings is not provided.

The DE 10 2006 037 365 A1 discloses a device for transporting moldings by means of suction spiders arranged on transverse traverses, for example between the presses of a press line. For this purpose, the cross members each consist of two, in at least one spatial direction offset from each other or adjustable arranged part crossheads that allow for handling of multiple parts on the one hand different Unterwerkzeughöhen within a press stage and on the other hand optimal alignment with different moldings.

To DE 20107376 is another device for the transport of molded parts between the processing stages of a multi-stage transfer press or press line known, in each processing stage each in or transverse to the transport direction juxtaposed multiple tools for a double or quadruple part production can be used.

For the transport of these multiple moldings corresponding holding means halves can be used per processing stage, which allow as a side movement independent spatial positional orientation of the moldings. Both of the latter solutions of the prior art have in common that the flexibility is limited to the fact that the different multiple parts are on the one hand reshaped by a common movement profile of the tappet and, on the other hand, transported by a common and synchronous main movement of the handling device from one processing stage to the next.

The DE 10125065 describes a method for producing a two-half shell structural part, which are connected to one another following the previous forming stations in a terminal station of a press line by crimping, wherein the adhesive connecting the half-shells in an arranged before the terminal station orientation station is applied. The The position of the shells associated tools in the forming stations of the press line and their transport between the forming stations and in and out of the orientation before entry into the terminal station is not disclosed.

Task and advantage of the invention

The invention has for its object to design a method and apparatus for a press line consisting of several individual presses, in particular for parallel production of multiple moldings so that for adjacent tools per single press on the one hand independent path and force curves of the plunger as the main axis and, if necessary, the drawing cushion as a minor axis and on the other hand, if necessary, independent of each other movements of the handling system for optimal part-specific process conditions and output can be achieved. In addition, a flexible workpiece flow direction should be possible in the press line to u. a. If necessary, the joining of technologically different moldings following the forming operations without an intermediate storage or Orientierstation, for example, to apply adhesive perform. Furthermore, the energy consumption from the supply network, the cycle-related load fluctuations and the network perturbations should be minimized.

According to the invention the object is achieved with the features of the method according to claim 1 or 2. Further detailed embodiments of the method are described in claims 3 to 15. The device for carrying out the method is achieved by the features described in claim 16 or 17. Further detailed embodiments of the device are described in claims 18 to 30.

The gist of the invention is to equip a servo press system with in-line servo presses so that at least one multi-ram servo press is provided, each having at least two systems for ram and cushion actuation, as well as a common system or two separate ones Systems for the transfer drive, the separate systems are controlled by means of independently controllable drives synchronous or asynchronous with the same or different clock rate to each other.

In addition to the dual plunger system with two adjacent plungers per press, preferably for parallel production of different double parts come in Quattro plunger system four independently controllable plunger, preferably for parallel production of different quadruple parts are used.

In the dual plunger system, the two plungers are arranged either in the press line longitudinal axis or preferably transversely to the press line longitudinal axis adjacent to each other. In the Quattro plunger system, the four plungers are preferably arranged in pairs adjacent to each other in the press line longitudinal axis.

In the Dual and Quattro tappet system either each system can drive a separate motion profile for different parts, or two adjacent or all systems travel electronically synchronized for a single part or similar double or quadruple parts. Alternatively, the systems for synchronous operation are mechanically coupled.

The advantage of using systems for the multi-part production is that by a flexible specific adaptation of the drive, cushion and transfer parameters as required for each part optimal process conditions and on the other hand an independent optimal clock rate can be achieved.

In a press line whose individual presses according to the prior art in each case have a single plunger advantage mentioned above can not be used because the set motion profile of the single plunger acts simultaneously on, for example, two different, adjacent tools and their moldings to be produced. If, in this case, the movement profile and the achievable clock rate are optimally adjusted to the most unfavorable of the two molded parts, these parameters do not represent an optimum for the adjacent molded part, so that on the one hand the quality is influenced as a result of this compromise and, on the other hand, the potential reserves in the output are used up stay.

In the transition to, for example, a dual ram system according to the invention, it is now possible to assign the different mold parts of the adjacent tools each one for quality and output optimal motion profile for the transformation. In addition, the different shaped parts can be impressed on each other a different force profile.

When in the direction of passage of the multi-ram servo press successive double parts whose dual ram system is arranged in press line longitudinal axis one behind the other, it is expedient that the supply and removal of the double parts in and out of the dual ram system is carried out synchronously with each other with a common transfer movement.

When lying in the direction of passage in the multi-ram servo press adjacent double parts, the dual ram system is arranged transversely to the press line longitudinal axis side by side, it is possible that the supply and removal of the double parts in and out of the dual ram system either with a common transfer movement in synchronization with each other or can be carried out asynchronously to one another with a transfer movement progression that can be separately allocated to each molding.

If a multi-ram press with a Quattro ram system is used, in the case of the manufacture of in the direction of passage in each case behind or adjacent double parts, the double parts each associated pestle pair can be moved synchronously.

In addition to the electronic synchronization of individual tappets in a dual or quattro tappet system, an additional mechanical coupling is optionally possible.

In the transition to a Quattro plunger system according to the invention, it is also possible to assign the trailing and adjacent quadruple parts each one for quality and output optimal motion profile for forming. In this case, the feeding and removal of the quadruple parts into and out of the quattro plunger system can be carried out asynchronously with one another either with a common transfer movement progression synchronously with one another or with a transfer movement progression which can be separately allocated for the two adjacent mold parts.

It is also possible that behind and next to each other quadruple parts are produced in a multi-ram servo press either with a press line longitudinal axis one behind the other or with a transverse to the press line longitudinal axis juxtaposed dual ram system. In this case, the dual-tappet system associated with mold pairs can each be made with each other with a separately assignable separately ram motion course. In the case of the dual ram system arranged behind one another in the press line longitudinal axis, the feeding and removal of the quadruple parts into and out of the dual ram system takes place synchronously with a common transfer movement progression.

In the other case, with the dual ram system juxtaposed transversely to the longitudinal axis of the press line, the feeding and removal of the quadruple parts into and out of the dual ram system can be asynchronous to each other either with a common transfer movement progression synchronously with each other or with a transfer movement path that can be separately allocated for the two successive mold parts respectively.

In further embodiments, it is possible to produce so-called triple parts in a multi-ram servo press. In this case, in a first case with a dual ram system arranged one behind the other in the press line longitudinal axis, the multiple mold parts can be positioned as a double part lying next to one another and a single part lying in front or behind it.

In a second case with a transverse to the press line longitudinal axis juxtaposed dual ram system, the multiple moldings can be positioned as a lying behind double part and right or left lying next single part.

For each of the double and single parts, an independently controllable plunger movement profile is possible in each case.

In the above-mentioned first case, the feeding and removal of the double and single parts into and out of the dual ram system takes place in synchronism with each other with a common transfer movement course.

In the above-mentioned second case, the feeding and removal of the double and single parts into and out of the dual ram system can take place asynchronously with each other either with a common transfer movement course synchronously with each other or with a transfer movement history separately assignable for the double part and single part.

It is also conceivable to produce the triple parts in a multi-ram servo press with Quattro tappet system, in which case the tappet pair associated with the single part is synchronously controllable. In the embodiment with double parts arranged next to one another in the passage direction and the single part positioned in front or behind, the feeding and removal of the double and single parts into and out of the quattro tappet system takes place synchronously with a common transfer movement profile.

In the embodiment with in the direction of passage successively arranged double parts and the right or left next positioned single part, the supply and removal of the double and single part in and out of the Quattro ram system either with a common transfer movement in synchronism with each other or with one for the double and single part each separately assignable transfer movement history asynchronous to each other.

The solution according to the invention further includes a triple ram system in which either a half, in press line longitudinal axis successively arranged dual ram system with a half, behind or arranged in front Quattro ram system or half, transverse to the press line longitudinal axis juxtaposed dual Pusher system with a half, arranged adjacent Quattro ram system can be combined.

Within the press line, the associated multi-ram servo presses can either be configured uniformly with in each case one of the dual, triple or quattro ram systems according to the invention, or the different ram systems are used in mixed form.

It is also conceivable that within a press line, one or more single presses with mono-tappet system combined with at least one multi-ram press in the embodiment with dual, triple or Quattro tappet system find application. All solutions have in common that the supply of the starting materials for the molded parts to be produced is primarily taken over as boards of a positioned in front of the head press of the press line platinum feed. The device equipped as a dual board feeder is capable of supplying both single and multiple boards synchronously or asynchronously at the same or different clock rate to the first drawing operation in the head press. The dual board feeding device contains within the technological process, consisting of the separation of boards from a stack of boards, the need-based control of double sheet, the transport of the boards in a transfer station with interposed as needed washing and / or Belöleinrichtung two separately controllable, in pairs Passing direction juxtaposed associated devices. These devices are in the case of supplying large single boards and in the direction of passage successively arranged double boards synchronously controllable. In the case of double boards or quadruple boards arranged next to one another in the passage direction, the device components assigned to the right and left lanes described above can be controlled either synchronously or asynchronously with the same or different clock rate relative to one another.

As an alternative to feeding blanks separated from a stack of blanks, it is conceivable to cut blanks from a strip unwound from a coil. For this purpose, a two-component dual-belt system is advantageously arranged side by side in the direction of passage, the integrated scissors cut the boards from the belt before feeding into the transfer station. The right and left lane respectively associated tape system of the dual-band system is controlled either synchronously or asynchronously with the same or different clock rate to each other.

In known press lines, the single presses with a mono-tappet system can advantageously be controlled in phase with one another in order to achieve an increased productivity in connection with the press-fitting devices connecting the individual presses.

In the solution according to the invention, the use of a phase offset between the tappets adjacent to each other in the dual or quattro tappet system within the multi-tappet servo press can advantageously be utilized in the case of the tappet lying one behind the other in the transport direction, the free movement for the removal and feeding of the turret lying multi-shaped parts in the common molding transport for increased productivity is improved.

In the case of transverse to the transport direction adjacent mold parts, the phase offset between the adjacent plungers allows, for example, the required time offset in the production of adjacent, technologically different moldings to this after the forming operations by means of a dual transfer system with a time delay in one of the multi-ram servo presses or to position a separate processing station for a subsequent joining operation to a common compact part.

This staggered transport of the moldings to be joined can furthermore be used advantageously to enable, for example, the application of adhesive by means of a suitable device after the first molded part has been deposited and before the second molded part has been positioned.

Alternatively, the preparation for the joining process with, for example, applying adhesive to at least one of the adjacent molded parts can already take place in the multi-ram servo press upstream of the joining operation. In this case, in the case of a smaller number of forming operations relative to the adjacent shaped part, the relevant ram can be coupled with a device for applying adhesive instead of a forming tool, wherein the motion sequence which can be controlled independently by the adjacent ram can advantageously be used for the operation for adhesive application.

If the main movement of the single rod of single presses of a prior art press line can be controlled with servomotors, the phase offset of the single presses can be controlled be used with each other to perform an energy exchange between the servomotors of the individual presses with each other with the aim of relieving the energy networks. It is a disadvantage that the phase offset of the active power reference occurring in the cycle of the forming process and the active power supply occurring in the form of feedback can not be optimally adapted to the phase offset of the main movement of the plunger of the individual presses.

In the solution according to the invention, it is now possible, in the case of manufacturing in the direction of succession and juxtaposed multiple parts to optimize an energy exchange between the adjacent out of phase controllable multiple tappets so that the phase offset of the occurring in the cycle of forming active power reference and the active power delivery with the phase offset controllable movement of the adjacent plunger, for example, the dual plunger system is largely synchronized.

In the multi-ram servo press, the independently controllable individual rams are driven by means of servo drives. In addition to the applicability of servo-controlled hydraulic drives with rams that can be driven by the linear force of hydraulic cylinders, the following description focuses on the application of servo-controlled mechanical drives for the main movement of the individual tappets.

Depending on the size of the pressing force, in a first stage of expansion, drive modules are used for the ram drive, depending on the size of the pressing force, from a lifting mechanism designed as a direct drive without an intermediate gear for generating the ram movement. For this purpose, on the one hand linear motors without motion converter and on the other hand linear gear with motion converter, such as rotatably driven spindle nut or lever mechanisms with translational output movement of the plunger applicable.

In the case of a lever mechanism, it is possible that the lifting gear and associated servo drives are aligned either in or across the press line longitudinal axis. As a lever mechanism, for example, an existing from an eccentric shaft with operatively connecting rod crank mechanism can be used.

In the case of the dual ram system, two lifting gears each act on the associated ram whose eccentric shafts are driven in opposite directions by means of electronically coupled servomotors. Both pestle belonging to the dual-ram system can be operated synchronously or asynchronously to each other.

With the use of the crank mechanism, the advantages of the path-traversing the lower reversal point can be used for a high clock rate.

The activation of the servomotor or motors enables the generation of flexible movement profiles of the plunger. Different lift heights of the plunger can be realized by selecting a 360 ° rotation mode or a <360 ° pendulum mode on the crankshaft.

To meet the technical and personnel safety requirements, safety brakes can be used as mechanical holding devices. The brakes can each be integrated in the engine or positioned separately on the free shaft end of the crankshaft.

It is also possible that hydraulic servo drives are used.

Tool change table systems are available for changing the tools in the multi-ram servo presses. In a basic variant, the tools associated with each ram of a multi-ram servo press can be jointly extended and retracted from the system by means of a mono-tool changing table system, whereby either one shuttle table per multi-ram servo press can be used for one-sided or one interchangeable table pair for two-sided alternating operation. If it is advantageous in a multi-ram servo press with arranged transversely to the transport direction dual ram system, the tools associated with each plunger independently from the system and retract, in a further embodiment, a dual-tool changing table system can be used, the two change tables are assigned, the direction of travel is either one-sided or opposite directions on both sides. For short set-up times, in a further expansion stage, a pair of dual-tool change-table systems can be used per multi-ram servo press by assigning a pair of change-over tables to each of the adjacent rams. While in each case a shuttle table of the pair can be positioned with a transverse travel in a parking position, the adjacent shuttle table of the pair can be positioned with a combined transverse and longitudinal travel in a parking position offset in the transport direction.

It is possible by means of the dual tool change system to carry out a setup of the tools in the first pass track, while in the second pass track further production runs.

In the first embodiment is off 1 a press line 1 with three in press line longitudinal axis 9 consecutively arranged multi-ram servo presses 2.1 - 2.3 in the first embodiment with each transverse shaft drive visible. Each multi-ram servo press 2.1 - 2.3 is a dual ram system 10 associated with the two separate, independently driven ram 16 each transverse to the press line longitudinal axis 6 are arranged side by side. The two pressure points 17 of the plunger 16 are each about a screw jack 18 with the system for the ram drive 5 in active connection. As a lifting gear 18 used in the embodiment, a crank mechanism 19 that of an eccentric shaft 20 and a connecting rod 21 consists. Alternatively, acting as a direct drive linear motors or drives with spindle nut system can be used. The to Hubgetriebe 18 associated eccentric shaft 20 is drive side with a servo drive 8th coupled. The servo drives 8th and the associated lifting gear 18 are in press line longitudinal axis 9 aligned. The two, the respective pestle 16 of the dual ram system 10 assigned servo drives 8th are electronically linked on the control side. In addition to a synchronous control of both servo drives 8th is also an asynchronous control conceivable. The latter mode is particularly for a parallel control of the plunger 16 with compensation of the asynchronous elastic springing of the two pressure points occurring as a result of off-center loading 17 advantageous usable.

It is equally possible the two, in press line longitudinal axis 9 aligned eccentric waves 20 to couple mechanically and this either with the two opposite servo drives 8th or just one servo drive 8th to drive together.

The to the lifting gears 18 associated eccentric shafts 20 and servo drives 8th are in the headpiece 22 stored. At least one to a pestle 16 associated servo drive 8th is with a braking device 23 connected.

The tools used for the molding production each consist of a lower tool, not shown, on the in the tool room 24 retractable and extendable sliding table 25 is stored. The associated upper tool, not shown, is in each case on a plunger 16 attached.

In 2 is a press line 1 with four in press line longitudinal axis 9 consecutively arranged multi-ram servo presses 2.1 - 2.4 represented in the second embodiment with each longitudinal shaft drive. The difference compared to the first embodiment is essentially that the axes of the screw jack 18 each with associated eccentric shaft 20 , Connecting rod 21 and their servo drives 8th transverse to the press line longitudinal axis 9 On the one hand, the accessibility of the servo drives 8th at reduced distance of the multi-ram servo presses 2.1 - 2.4 is improved and on the other hand by the counter-rotating eccentric shafts 20 occurring lateral forces within a plunger 16.1 . 16.2 can be compensated.

Out 3 is the technological process for the production of a multiple molding 3 on a press line 1 with separate multi-ram servo presses 2 seen. The used dual ram system 10 The type transverse to the direction of passage serves for the parallel production of a molded part 26 with increased draw depth and a molded part 27 with low draw depth.

The two separate rams 16.1 . 16.2 associated tools of the first in the direction of travel multi-ram servo press 2.1 is fed by a board feed, not shown, in each case isochronously a circuit board and the drawn part produced in a first forming operation.

On the one hand each multi-ram servo presses 2.1 - 2.4 within the press line 1 a separate forming operation for the multiple molding 3 and on the other hand in the dual ram system 10 the multi-ram servo press 2.1 - 2.4 the tools for the moldings 26 and 27 each separate ram 16 are assigned, can be achieved with the independently controllable motion sequences optimal part-specific process conditions and application.

The mutually independently controllable motion sequences relate not only to the relative movement of the upper and lower tool by means of the main movement through the plunger 16 , but also refer to the side movements by means of the system for the die cushion drive 7 For example, in the head press as the first multi-ram servo press 2.1 in the press line 1 ,

The interaction of the main movement of the plunger 16 and secondary movement by means of die cushion drive 7 is schematic 4 based on the multiple molding 3 to 3 and section AA of the multi-ram servo press 2.1 seen. The illustration shows with the tool open in a working position within the sequence of movements after the deep-drawing process on the transport plane raised multiple moldings 3 , wherein the molding 26 with increased depth of draw in the left lane and the molding 27 is positioned with low draw depth in the right lane. The different part geometry are the path and force curves of the main movement of the plunger 16 and the secondary movement of the die cushion 7 flexibly adapted. It can for the molding 27 with low draw depth on the right lane, taking into account the freedom for the transport system, not shown here, a smaller stroke of the plunger 16 be set.

The kinematic movement of the two rams 16.1 . 16.2 Within a forming cycle, plunger travel = f (time) is in the associated diagram 5 shown. The part-specific kinematics for the two different moldings allows the molded part 27 with lower draw depth requires a shorter cycle time and thus a higher output can be achieved.

When using a tool on both plungers 16.1 . 16.2 of the dual plunger system 10 Covering molding as a single part are the freely programmable servo drives 8th electronically coupled so that a synchronous movement of the tappet pair 13 he follows. Alternatively, the two rams 16 mechanically coupled.

In a second embodiment according to 6 is a press line 1 with three in press line longitudinal axis 9 consecutively arranged multi-ram servo presses 2.1 - 2.3 and dual ram system 10 described in the direction of passage. In the embodiment with transverse shaft drive are the axes of the lifting gear 18 each with associated eccentric shaft 20 , Connecting rod 21 and their servo drives 8th along the press line longitudinal axis 9 aligned. Two act, transversely to the press line longitudinal axis 9 adjacent lifting gear 18 on a common pestle 16.1 . 16.2 ,

The used dual ram system 10 of the type "in the direction of passage one behind the other" serves for the parallel production of the two different molded parts 3 , Out 7 is the technological process in a first embodiment with two different moldings 3 one behind the other in the direction of flow. First, the first multi-ram servo press 2.1 by means of the sheet feeding device, not shown, both parallel in the direction of passage successively arranged boards 28.1 . 28.2 fed. During the subsequent pressing process, the tappet travel and force profile of the two tappets 16.1 . 16.2 on the part-specific requirements of the different molded parts 4.1 . 4.2 Voted. Subsequently, the drawn moldings 4.1 . 4.2 by means of a transfer device together in synchronism with each other from the first to the second multi-ram servo press 2.2 transported. This process is repeated along the forming operations until removal from the last multi-ram servo press 2.4 ,

In a second embodiment according to 8th be used instead of the moldings 4 two different double parts 11.1 . 11.2 manufactured in the direction of passage one behind the other, with each double part 11.1 . 11.2 preferably consists of a right and left mold part with substantially the same forming requirements. For each pair of these geometrically mirrored moldings is on the associated plunger 16.1 . 16.2 a for the molding quality and application optimal ram travel and force course adjustable. The technological process is essentially analogous to the description 7 , being in the first multi-ram servo press 2.1 preferably a quadruple board 28.1 - 28.4 is supplied.

If compared to the above embodiment, either within a double part or for a quadruple part differentiated process conditions are set, can within a multi-ram servo press 2 a Quattro tappet system 12 be used according to the third embodiment. This is schematically in plan view in FIG 9 shown. After feeding the boards 28.1 - 28.4 can in a first embodiment in the subsequent pressing process the Stößelweg- and -Kraftverlauf the four plunger 16.1 - 16.4 in the first multi-ram servo press 2.1 on the part-specific requirements of the different molded parts 14.1 - 14.4 be matched.

In 10 is the press line 1 according to the third embodiment with three in press line longitudinal axis 9 consecutively arranged multi-ram servo presses 2.1 - 2.3 and Quattro tappet system 12 demonstrated. Every pestle 16.1 - 16.4 of the Quattro plunger system 12 is a lifting gear 18 each with associated eccentric shaft 20 , Connecting rod 21 and their servo drive 8th assigned.

Out 11 is the Quattro tappet system 12 according to the third embodiment in a second embodiment with two different multiple parts 3 can be seen transversely to the passage direction. Because in this case both the boards 28.1 . 28.2 as well as the moldings 4.1 . 4.2 geometrically the in press line longitudinal axis 9 in the respective track successively arranged plunger 16.1 . 16.3 and 16.2 . 16.4 , Cover are the associated plunger pairs 16.1 . 16.3 and 16.2 . 16.4 Synchronized with each other in the movement. The Quattro ram system 12 acts in the movement analogous to the dual ram system according to the embodiment 3 ,

It is also possible in a dual ram system 10 to 12 in the respective track a per se geometrically mirror-image double part 11.1 . 11.2 to position and in each case with a common plunger-way and force curve of the associated plunger 16.1 . 16.2 to shape.

13 shows one from the press line 1 isolated multi-ram servo press 2.1 in the design with Quattro plunger system 12 , The lifting gear 18 with associated servo drive 8th for the individual pestles 16.1 - 16.4 are in press line longitudinal axis 9 aligned, wherein in each case the two in the direction of passage successively arranged lifting gear 18 in a gear box 31.1 . 31.2 are stored together. The gear boxes 31.1 . 31.2 are based in the plane on the frame-shaped crossbars 29.1 . 29.2 off, on the uprights 32 are positioned. The gear boxes 31 , Crossbars 29 , Stand 32 and table 33 are by tie rods 34 operatively connected. The pestles 16.1 - 16.4 the Quattro tappet system 12 are on the one hand diagonally opposite in the corner of the stand 32 and on the other hand adjacent to each other by means of the in the crossbars 29.1 . 29.2 located guides 30.1 . 30.2 stored. By means of a support in the headpiece guide 35 (please refer 11 ) are the pestles 16.1 - 16.4 longitudinally adjacent to each other indoors.

Out 14 is the tool room 24 of two adjacent multi-ram presses 2.1 . 2.2 with representation of the system for the parts transport drive 6 seen. The dual ram system 10 every multi-ram press 2.1 . 2.2 , each consisting of the two plungers 16.1 . 16.2 is a dual transfer system 43 assigned. As described in 4 and 5 are in the left and right lane of the multi-ram servo presses 2.1 . 2.2 Due to the different parts geometry differentiated ram and cushion movement profiles mobile, which also allow a mutually different clock rate. These are the two, the dual transfer system 43 associated dual transfer system halves 44.1 . 44.2 independently controllable. The part transport takes place between the tappets which can each be controlled out of phase in the passage direction 16 by means of the dual transfer system halves 44 Actively connected vacuum suction spiders 45 which perform a primarily two-dimensional lift-lowering and feed-return movement for direct transport from one stage to the next. The parts conveyor can drive side with linear axes or with operating in a vertical or horizontal plane articulated arms 46 or combinations. For the realization of spatial orientation movements of the moldings 4.1 . 4.2 Additional drive elements can be integrated. In addition, spatially acting multi-axis robots can be used as part conveyors. The asynchronous possible mode of operation between the left and right lane does not only relate to the transport of molded parts between the tappets 16 but also excludes the feeding of the boards 28 in the first multi-ram servo press 2.1 and the removal of the moldings 4 from the last multi-ram servo press 2.n one.

An alternative mode of operation of the dual ram and transfer system with separate means of transport is off 15 can be seen in the manufacture of a two plunger 16.1 . 16.2 Covering tool for a single part 15 both the dual ram system 10 as well as the dual transfer system 43 are controllable synchronously to each other.

The multi-ram servo press system can also be advantageously used, for example, to connect different, the press line in or transverse to the longitudinal axis passing double parts in one of the last operations to a compact part by means of joining operation. These are in 16 the last two stages of the multi-ram servo presses 2n-1 . 2n shown, wherein in the stage 2n-1 with the dual ram system 10 consisting of the plunger 16.1 . 16.2 the two moldings 4.1 . 4.2 be made separately from each other. By means of the dual transfer system 44 be the two moldings 4.1 . 4.2 time-delayed one after the other in the stage 2n for a subsequent joining process to a common compact part 47 positioned. With a simple system for the parts transport drive 6 for conveying the compact part 47 from the stage 2n is the workpiece transport from the tool room 24 the press line 1 completed.

It is also conceivable that the joining process instead of in the multi-ram servo press 2n is performed in a subsequent to the press line separate processing station.

One of four multi-ram servo presses 2.1 - 2.4 existing press line 1 each with a dual ram system 10 and associated system for parts transport drive 6 for an alternate molding transport in and across the press line longitudinal axis is off 17 seen. That from the board 28 manufactured molding 4 is by means of schematically illustrated system for parts transport drive 6 into the tool room of the ram 16.2 the following multi-ram servo presses 2.2 along the press line longitudinal axis 9 promoted. After forming, the molding becomes 4 then for the next follow-up operation to the adjacent tool space of the plunger 16.1 by means of a transverse to the press line longitudinal axis 9 operating system for parts transport drive 6 emotional. If, depending on the required forming operations already a discharge of the molding 4 from the multi-ram servo presses 2.3 possible is the multi-ram servo presses 2.4 in an alternative mode of operation in parallel as a transfer press 52 be used, with their transport direction transverse to the press line longitudinal axis 9 he follows. The individual steps of the tool set 53 are under both pestles 16.1 . 16.2 of the dual plunger system 10 whose motion is electronically synchronized for a parallel operation. That to the multi-ram servo presses 2.4 associated dual transfer system 43 is also for a common transport of the moldings of the tool set 53 synchronized.

Out 18 is the tool room 24 a multi-ram servo press 2.1 with dual ram system 10 seen in cross-section, in which the transverse to the transport direction juxtaposed plungers 16.1 . 16.2 one tool each for the adjacent molded parts 26 . 27 assigned. The multi-ram servo press 2.1 as the so-called head press of the press line is with a system for the die cushion drive 7 for driving the tool-specific plate holder 49 equipped, taking the the pestles 16.1 . 16.2 separately assigned cushions in the table 48.1 . 48.2 synchronous or asynchronous to each other are controllable. The pillows 48.1 . 48.2 preferably have a servo-electric drive, not shown, whereby during operation a direct energy exchange pillow plunger 50 is controllable so that the generated during the drawing process in the cushion regenerative braking energy to the servo drive 8th the associated plunger 16 can be fed.

In addition, an energy exchange plunger pestle 38 between the adjacent out of phase controllable tappets 16.1 . 16.2 so optimized that the phase offset of the active power reference occurring in the press cycle and the active power delivery with the phase offset of the controllable movement of the adjacent plunger 16.1 . 16.2 is largely synchronized. This out-of-phase operation also allows use of the energy exchange pillow cushion 51 ,

The proportional energy balance between the mutually phase-shifted tappets 16.1 . 16.2 in the illustrated dual ram system is in 19 described in more detail. The upper diagram shows the power curve of the servo drive 8th of the plunger 16.1 , The lower diagram shows the power curve of the servo drive 8th of the plunger 16.2 , shown. During the press cycle, load-dependent fluctuations in the performance curve occur during the press cycle. This fluctuation occurs in the two quadrants active power (+) 41 and active power delivery (-) 42 on. While in the phase of the active power reference 41 Energy is purchased, it comes during the phase of active power delivery 42 for energy recovery. Between the two phases is a load-dependent phase offset 39 in front.

Because the multi-ram servo presses 2.1 - 2.n within the press line 1 During the passage of the moldings are also operated by means of phase offset, the energy exchange can also between the servo-drives 8th the successively arranged in the transport direction multi-ram servo presses 2.1 - 2.n be used.

The following are the possibilities of tool change in the multi-ram servo presses belonging to the press line 2.1 - 2.n described.

Out 20 is a mono tool change table system 54 with one-sided retraction and extension direction, with the adjacent tools 63 are each positioned on a common shuttle table.

To shorten the set-up times comes after 21 a pair of mono-tool-change table system 55 with double-sided entry and exit direction for use.

For a dual tool change table system 56 to 22 Can the tools 63 separately associated changing tables either one or both are moved together with one-sided retraction and extension.

When the tools 63 separately assigned changeover tables are each moved individually or together with both sides inward and outward direction, the execution comes after 23 for use.

To shorten set-up times and tools 63 separately assigned shuttle tables comes after 24 a pair of dual tool changer system 57 with double-sided entry and exit direction for use.

Out 25 is a pair of dual tool change table system 57 in a second embodiment with two-sided entry and exit direction visible.

While each a change table 57.1.1 . 57.1.3 of the pair is positionable with a transverse travel in an outboard parking position, the adjacent shuttle table 57.1.2 . 57.1.4 of the pair with a combined transverse and longitudinal travel in a staggered in the transport direction first parking position 58 in the plane of the gap 59 between adjacent multi-ram servo presses 2 be positioned.

It is by means of the dual tool change system 57 possible to equip the tools 63 in the first pass track 61 while in the second pass track 62 the further production runs.

In a third embodiment of the dual tool change table system 57 with two-sided entry and exit direction and combined transverse and longitudinal travel analogue according to 25 are the shuttle tables 57.1.2 . 57.1.4 in a second parking position 60 in the plane of the upstream or downstream multi-ram servo press ( 2 ) positionable.

To feed the boards in the pulling operation of the first multi-ram servo press 2.1 comes a dual board feeder 64 used in a first embodiment in synchronous operation for a common single part 66 out 27 is apparent.

The dual board feeder 64 consists of two separately controllable, in the direction of passage next to each other arranged devices. Each of these devices contains for loading the boards 66 a pair of board stacking cars 65.1 . 65.2 and 65.3 . 65.4 , where the designed as a single part boards 66 are each positioned in common on a pair of board stacking cars. By means of the board feeder 68.1 . 68.2 become the boards 66 alternately initially from the board stacker 65.3 . 65.4 isolated and the conveyor belt 69 fed at the same time 90 ° rotation. The board 66 covers the two to the conveyor belt 69 associated subbands. After passing through a washing and / or oiling station as needed, the boards reach a transfer position for further transport by means of one of the dual transfer system halves 44 , When the board stacking car 65.3 . 65.4 are emptied, on the blank stacker cars 65.1 . 65.2 switched on the opposite side.

In 28 is an alternative use of the dual board feeder 64 in asynchronous operation for different double parts 67 described. The double parts 67 are each one of the board stacking cart retracted into the system 65.2 . 65.4 assigned and of these by means of a Platinenfeeders 68.1 . 68.2 individualizable. Every double part 67 then passes over one of the sub-bands of the conveyor belt 69 into the transfer station for further transport with the dual transfer system 43 , During the board separation from the board stacking cart 65.2 . 65.4 be new stacks of double parts 67 on the extended board stacking cart 65.1 . 65.3 positioned.
