- the press should be used for forming or forging of workpieces, compaction or embossing and also for cutting materials of any kind and as a transfer press and for classification in press lines.
- the state of the art generally teaches that the plunger is regularly joined by a combination of tie rods, also in combination with a tie rod
- Drive unit is driven in a substructure of the press.
- presses with sub-drive are mainly designed as presses with low nominal force and high stroke rate and less for so-called large presses. In such forming presses, this is justified by the fact that because of the expansive arrangement of the lower drive little space in the table for drawing equipment such as drawing cushion and possibly for the removal of cuttings or the arrangement of ejectors and accessibility for maintenance and repair remains.
- the tie rods / Ceipleuel be arranged in stands and guided - at least above the substructure - which are connected to a located above the stand, forming the plunger crossbar and as quasi Pres sengestell for the forces occurring (action and reaction forces) are designed.

- the die cushions can be designed as single-point or multi-point drawing cushions.
- Movement phases of the die cushion, which run without mechanical contact with the press ram, are controlled by electronic position cam discs, while the
- Pulling cushion reaches the plunger movement, which can be maintained even with changes in speed and emergency stops the plunger movement, without any special
- Total drive force of the plunger is the sum of the forces that are necessary to reshape the part plus the pull cushion force acting against the ram force.
- both parallel and sequential process steps have an advantageous effect on the operation of the machine, but they have no effect on the basic structure of the machine and thus the power flow.
- the object underlying the invention aims specifically in the power flow and thus in the entire structure of the machine to design such a solution that the cushion force takes place within a closed power flow between the cushion and plunger and thus the total force must not be increased by the cushion force, but the total pressing force corresponds only to the forming force.
- a die cushion device is to be improved in such a way that the control behavior is improved while reducing the control and regulation effort, and a variable power distribution on the blank holder can be made possible with a design which is as compact as possible.

- linear direct drives are linear motors in the interior or exterior of the
- Pressure cheek provided.
- the linear motor belonging to the secondary part is attached to the pressure cheek, depending on the power requirement one or more in the press table mounted primary parts are opposite.
- the external linear motor also allows the use of multi-part pressure cheeks sharing of primary or secondary parts by adjacent die cushion devices.
- the sheet holder can be controlled by means of a combination of at least one linear direct drive and at least one operatively connected to an electric drive linear converter.
- Sheet metal holder which allows in conjunction with the movement of the plunger pulling the mold parts per press stroke.
- varying pressures can be set at the associated blank holder zones, wherein u.a. the energy obtained during the drawing phase in the braking mode of the electric drive can be fed back.

- the pull rod 2.1.2 is moved freely in the locking unit 3.4.1 according to phase III, so that the intermediate plane 3.4 by the pressure from the upper chamber 3.6.1.1 of the cylinder 3.6.1 of the first force-generating means 3.6 held in the lower layer U (Fig. 1) and then to
- the carrier unit of the pulling device 3.3 (eg Fig. 2) as intermediate plane 3.4 moves to the upper starting position and immediately before reaching the first position by means of a coupling element analogous to the locking unit 3.4 .1 the effect closure can be made.
- a second construction variant of the inventive press 1 is shown with a translationally coupled operative connection.
- FIG. 5 A third construction variant of the press 1 according to the invention with a translational coupling is shown in FIG. 5, in which the first construction variant is moved analogously, but only the first force-generating means 3.6 is required, the function of the second force-generating means 3.7 shown in FIG Pressurization of the piston 3.4.2 in the same of FIG. 3 acting locking unit is exercised.
- the method is expediently carried out so that the carrier unit is pre-accelerated by a value reduced by the value of the speed of the tappet 1.1, which value is preferably 80% of the speed of the tappet 1.1.
- a required for the forming process counterforce is applied by means of the apparent from Fig. 2.1 energy-saving power flow K, which power flow K without power loss from the first force-generating means 3.6 through its direct impact on the components of the carrier unit, the tie rods 2.1.2, the tappet 1.1, the tool shell 1.2, the workpiece 5 and the holder 3.3 is made and closed.
- the holder 3.3.1 is raised by the first force-generating means 3.6 or second force-generating means 3.7 or by temporary closure of the positive, frictionally engaged and / or non-positive operative connection up.
- control and regulating device 4 incorporated in FIG. 2 for recording, evaluation and control / adjustment, values or parameters for at least one of the
- Tension rods 2.1.2 mediated eccentric-rotary drive is due to the action of the telescopic pull-out 'a double-acting cylinder in the
- Koppelpleuel 2.1.3.1 created a meaningful translational operative connection to the components of the pulling device 3.1.
- the active connection can thus also be coupled and / or decoupled in alternation of the respective stroke H.
- the Koppelpleuel 2.1.3.1 is shown schematically to the left of the center line in the sense of a frictional-translational and right of the center line in terms of a hydraulic-Kaftschlüssigen translational operative connection.
- Coupling 2.1.3.1 symbolically shows the Fig. 7.1.
- the relatively movable one eccentric coupling element 2.3.2.1 integrated, so as to be able to operate the active connection coupled in the change of the respective stroke H and / or decoupled operate.
- the press 1 is provided with a parallel and linear guide 3.5.1 schematically illustrated in FIGS. 6.1, 6.2, 7, and 7.1 for the carrier unit with intermediate plane 3.4 or pressure cheek 3.5 or intermediate plane 3.4 and pressure cheek or only pressure cheek in FIG Free space 3.3.2 of the substructure 3 executed.
- the rotational coupling shown in Fig. 4 2.3 of the drive strands 2.1 of the drive device 2 is housed in the free space 3.3.2 or outside it, in which case an unillustrated motor 2.1.1 with connecting unillustrated control and regulating device 4 are used can.
- a new method for operating a press with sub-drive and a new press are created, wherein in the substructure a functional, technologically usable area - on the one hand in technological stages of pulling with a pulling device and energy-efficient drive kinematics and on the other hand
