- Forming method with a press having in a Ge entitled a closing by the force of a cylinder with a movable piston against a press table in a rectilinear motion stamp according to. of the claim 1 by the measures that the piston initially acts on the closing of the press on at least one toggle lever system and that with extension of the toggle lever system in the direction of movement of the piston and its rectilinear support against the
- the forming process according to the invention has a number of advantages, which in the division of the forming of a
- Another advantage results from the measure that when closing the press initially the hydraulic pad is extended, that the hydraulic pad is retracted with impact on a workpiece and that after stretching of the at least one toggle systems, the re-extending hydraulic pad completes the forming process.
- Knee lever systems is connected frame-fixed and that the punch has a hydraulic pad.
- the press according to the invention also has a number of advantages. When using a quick-lift piston, initial closing speeds of the toggle systems from 800 mm / s to 900 mm / s can be achieved. In addition, the
- Knee lever system has a lever which is connected to a first
- Tied axis is connected, that the continuous leg is connected at the other end on a third axis of rotation in a frame-fixed receptacle, wherein the three axes of rotation in the closed position of the press in a line in the
- Cylinder or its height adjustment is a simple one Adapting to workpieces and dies of different
- the receptacles are arranged at the free ends of threaded spindles, in particular with a trapezoidal thread extending in
- Stands in spindle nuts set adjustable in height and, for example, motorized.
- Lock can then secure the height adjustment.
- the geometry of the toggle systems is primarily geared towards a quick closing of the press. It is therefore provided that the distances between the first and the second axis of rotation and the second and the third axis of rotation are equal. Thus, these lever sections form an isosceles triangle when opening the press.
- the measure that the second and the fourth axis of rotation are arranged on a circular path about the third axis of rotation, may serve this purpose.
- At least two toggle lever systems will be provided, which are arranged with each pointing toward each other, outgoing legs of the toggle lever on the stamp, and that the free ends of the outgoing legs of the toggle lever are connected via the connecting lever to a common, piston-resistant platform. If four toggle systems are used, these will be in two next to each other
- connection levers are rotatably connected.
- connections between levers, receptacles and / or webs are formed like pliers by a first part to be connected of two tabs of the sections in a cross section
- U-shaped second part is bordered and by both parts by a bolt in aligned holes as
- Rotary axis are connected.
- one end of the first part is weakened to a pin and provided with a rounding, that by weakening two perpendicular to the pin flat sides

- FIGS. 1-3 a press 1 according to the invention is shown in a three-sided view.
- the press 1 is of per se conventional gantry design with two stands 2,3 and the uprights 2, 3 connecting top chord 4 of
- Fig. 1 shows the press 1 in a closed position in which an upper die 5 of a punch 6 is moved against a lower die 7 of a press table.
- Stamp 6 is defined in the upper flange 4
- Hydraulic cylinder 8 is provided, the piston 9 acts on here four identically formed toggle lever systems 10,11, see. Figures 15-18.
- a comparatively long double cylinder is preferably used, which is designed for very fast strokes, so that in particular for a hot forming of a workpiece on the toggle systems 10,11 the dies 5,7 can be quickly closed.
- the punch 6 further has a dioecious hydraulic pad 14, on the underside of the upper die 5 is fixed.
- Fig. 1 shows the hydraulic pad 14 extended, thus the upper die 5 in its understen position.
- Each knee lever system 10,11 has a first lever 15 which at a first, here lower end 16 via a rotation axis 17 on the hydraulic pad 14 of the punch. 6
- the pin 32 is bordered by two tabs 27,28 of the continuous leg 29 of the toggle lever 25, which also again have aligned holes 30,31.
- the aligned holes 26,30,31 bolt as a rotation axis 35 of the lever 15 and the toggle lever 25 are hinged together.
- the other end 34 of the continuous leg 29 of the toggle lever 25 is weakened again to a pin 36 and provided with a bore 37.
- the pin 36 is bordered by two tabs with aligned holes of a receptacle 38 and there is a connection by a bolt as a rotation axis 39th
- connecting lever 46 also holds in the manner explained above with two tabs like a pliers a web 48, the underside of a piston-fixed
- Platform 49 protrudes, and is pivotally connected thereto via a bolt as a rotation axis 50.
