Definitions

  • the invention relates to a press with a C-shaped frame, comprising a first linear motor facing away from a pressing point at a central portion of the C-shaped frame.
  • Presses are common in modern manufacturing processes. For example, presses are used for joining (e.g., press-fitting bushings), severing (e.g., cutting sheet metal strips), master forming (e.g., pressing powders into bodies), and forming (e.g., bending or deep-drawing sheets). Even these few examples show how versatile presses are used in technology. In principle, a distinction can be made between presses with an open or C-shaped frame and presses with a closed or O-shaped frame. The invention now relates to presses with C-shaped frames in which the asymmetric structure without additional measures leads to a springing of the frame as soon as a force is applied to the pressing site.
  • JP 02-274400 A2 a press with a C-shaped frame, in which a springing of the frame by two L-shaped arranged on the frame hydraulic cylinder to be compensated.
  • the DE 30 27 495 A1 discloses another example in which a springing of a frame by a hydraulic cylinder facing away from a pressing point to be counteracted.
  • the US 5,097,734 shows finally a last example of a press, in which a springing up of a C-shaped frame by means of counterbalancing cylinders is counteracted.
  • the force of the compensating cylinder is introduced via a linkage in the frame.
  • the DE 102007020166 A1 discloses a press according to the preamble of claim 1.
  • the object of the invention is therefore to provide an improved press, in particular one in which a force is reduced to the central part of the C-shaped frame.
  • the object of the invention is achieved with a press according to claim 1, namely a press of the type mentioned above, additionally comprising a pressing point facing, the second linear motor at the central portion, wherein the linear motors are provided for a counteracting drive, such that a springing the C-shaped frame is counteracted.
  • the linear motors act in each case between two mutually distanced fastening points on the central portion of the frame, ie one adjacent to the pressing point front of the central frame portion and the other at the side remote from the pressing point back of the central frame portion.
  • the middle part of the C-shaped frame is relieved by the other linear motor. For this reason, the frame can now be made smaller which results in lower material usage and therefore lower weight.
  • the middle section of the C-shaped frame has a constriction in the case of the linear motors. In this way, the effect of the linear motors can be increased, since the frame does not oppose the compensation forces of the linear motors so much resistance.
  • the press comprises a sensor for detecting a springing of the C-shaped frame and an associated control, which is prepared for driving the linear motor, so that a springing of the C-shaped frame is counteracted.
  • a deformation of the frame can be fully compensated.
  • the control also ensures that the force compensation is performed correctly under a variety of conditions and influences.
  • the senor comprises a photosensitive position detection element which is arranged on one leg of the C-frame and a laser light source which is arranged on the other leg of the C-shaped frame, wherein the laser light source for illuminating the position detection element is provided
  • a photosensitive position detection element which is arranged on one leg of the C-frame
  • a laser light source which is arranged on the other leg of the C-shaped frame
  • the laser light source for illuminating the position detection element is provided
  • hydraulic cylinders are provided as linear motors. Hydraulic cylinders are particularly suitable for applying high forces.
  • a hydraulic system already exists in many presses anyway, so that these presses can be easily equipped or retrofitted with the inventive device.
  • a connecting line is provided between the hydraulic cylinders, such that a pressure is generated by the pressing process in the facing / averted hydraulic cylinder, which pressure is conducted to the facing / facing hydraulic cylinder.
  • a pump which pressurizes the hydraulic oil, that is, the system works passively.
  • This system is therefore particularly well suited for retrofitting presses that do not have their own hydraulic system.
  • the linear motors are driven so that the tip of the punch in a pressing operation with respect to a horizontal X-axis direction in a vertical plane through the center of the die or when the linear motors are controlled so that the orientation of the punch during a pressing parallel to the alignment of the die, ie in the vertical direction, depending on which variant the better bending results can be achieved.
  • Fig. 1 shows a schematically illustrated press 1 with a C-shaped frame 2 in an oblique view, wherein the frame 2 comprises a central portion 2a and two legs 2b, 2c.
  • the press shown consists of two frame members 2 which are connected by an upper crossbar 3, to which a punch 4 is attached, and a lower crossbar 5, to which a die 6 is attached.
  • the upper crossbar 3 by means of a drive, not shown (eg hydraulic cylinder, spindle drive, etc.) can be moved vertically in a conventional manner, in this way, punch 4 and die 6 from the rest position shown in a pressing position against each other ,
  • a drive not shown (eg hydraulic cylinder, spindle drive, etc.)
  • punch 4 and die 6 from the rest position shown in a pressing position against each other ,
  • this arrangement is not absolutely necessary for the invention, but rather it is also conceivable that the lower pressing bar 5 or both pressing bars 3 and 5 are displaceable.
  • Fig. 2 now shows the springing of the C-shaped frame 2 when a pressing force between the punch 4 and die 6 is generated.
  • the middle section 2a and the upper leg 2b are deformed (it is assumed that the lower leg 2c is firmly anchored in the ground).
  • the proportions of better representability are greatly exaggerated.
  • the deformations are usually much lower.
  • a photosensitive position detection element 7, which is arranged on the bottom or on the lower leg 2c of the frame 2 and which is irradiated by a laser light source 8, which is attached to the upper leg 2b the deformation of the frame 2 can be measured.
  • the position detection element 7 can be constructed, for example, from a plurality of juxtaposed photosensitive cells. But other designs are equally applicable.
  • Fig. 3 now shows a first variant of a press 1 ', in which a first linear motor 9, which faces away from the pressing point, and a second linear motor 10, which faces the pressing point, counteracts the springing of the frame 2.
  • the first linear motor 9 acts between two attachment points on the rear side of the middle frame section 2a and the second linear motor 10 acts between two attachment points on the front side of the middle frame section 2a.
  • linear motors 9 and 10 hydraulic cylinder are provided as linear motors 9 and 10 hydraulic cylinder.
  • this is not to be understood as limiting the invention, because in principle other types of linear motors are also suitable, in particular spindle drives.
  • the first hydraulic cylinder 9 is now subjected to a first pressure p 1 , which leads to a pressure force between the attachment points of the first hydraulic cylinder 9 and to an increase in the distance between them.
  • the second hydraulic cylinder 10 is acted upon by a second pressure p 2 , which leads to a tensile force between the attachment points of the second hydraulic cylinder 10 and a shortening of the distance between them.
  • the middle section 2a in the region of the hydraulic cylinders 9 and 10 has an indentation b in order to increase the action of the hydraulic cylinders 9 and 10.
  • the pressures p 1 and p 2 can be actively set up by a hydraulic pump. It is also conceivable that the two hydraulic cylinders 9 and 10 are connected by a line. The system is passive.
  • Fig. 4 shows a press 1 "not falling within the scope of the patent, similar to that in Fig. 3 shown press 1 '.
  • the frame 2 is completely separated in the area of the hydraulic cylinders 9 and 10. The forces between the upper and lower part of the central portion 2a of the frame 2 are thus transmitted only by the hydraulic cylinders 9 and 10.
  • a mounted in the lower part bar 11 is mounted between two guides 12 arranged on the upper part.
  • the "classic" drive of a press 1 ", namely the linear motors for moving the upper crossbar 3 can therefore be dispensed with in principle and instead be taken over by the hydraulic cylinders 9 and 10.
  • the guide 12 can also be made relatively delicate, since ideally all moments are compensated and only forces act in the vertical direction.
  • Fig. 5 now shows the balance of power on a press 1 'as in Fig. 3 shown.
  • the pressing force F P acts.
  • the opposite frame force F R acts.
  • pressing force F P and frame force F R are equal in magnitude.
  • the forces F 1 and F 2 of the hydraulic cylinders 9 and 10 thus serve only the moment equals. In terms of magnitude, these forces F 1 and F 2 are comparatively large because of the short lever. It is also conceivable, of course, for the hydraulic cylinders 9 and 10 to take over part of the frame force F R. F 2 then becomes larger in size, F 1 smaller in amount.
  • Fig. 6 shows the balance of power on a press 1 "as in Fig. 4 represented and thus an extreme case of said assumption of the frame force F R , which is completely eliminated in this example.
  • Fig. 7 now shows an arrangement in which the two hydraulic cylinders 9 and 10 (not shown here) are regulated.
  • a hydraulic pump 14 is provided, which hydraulic oil from a reservoir 13 via valves 15 and 16 to the two hydraulic cylinders. 9 and 10 pumps.
  • the first valve 15 controls the first pressure p1 for the first hydraulic cylinder 9
  • the second valve 16 controls the second pressure p2 for the second hydraulic cylinder 10.
  • a sensor in the example shown this is the photosensitive position detection element 7 off Fig. 2 , which is illuminated by a laser light source 8) transmits the angular offset between punch 4 and die 6 (that is, here a length derived from the angular offset) to a controller 17.
  • the controller 17 determines from this signal control signals for the valves 15 and 16.
  • Die Hydraulic cylinders 9 and 10 can be controlled in this way so that an offset between the punch 4 and die 6 is completely compensated. This is especially in a press 1 "after Fig. 4 advantageous since between beam 11 and the guides 12 then no more moment is transmitted.
  • the control 17 can be constructed in principle from any commercially available controller. However, it is particularly advantageous if the controller 17 is constructed from a central processing unit with a memory connected thereto. In the memory then necessary for program execution steps and parameters are stored and retrieved at runtime from the central processing unit. Especially with a press 1 "after Fig. 4 this is advantageous since the control 17 can then also control the vertical displacement of the upper crossbar 3.
  • the linear motors 9, 10 are controlled such that the tip of the punch 4 is pressed in a pressing operation relative to a horizontal X axis. Axial direction in a vertical plane through the center of the die 6 or the linear motors 9, 10 are driven so that the orientation of the punch 4 in a pressing operation parallel to the alignment of the die 6.
  • a bending press is shown in the figures - the invention by no means exclusively on a bending press or a bending press of the type shown. Rather, the invention also relates to other presses, for example stamping presses, deep drawing presses, forging presses, embossing presses, etc. Furthermore, the invention is independent of the nature of the drive of the press and therefore equally relates to eccentric presses, toggle presses, crank presses, screw presses, hydraulic presses Finally, the application of the principle according to the invention is not limited to presses in which a compressive force acts between the two legs of the C-shaped frame, but can also be extended to cases in which a tensile force acts at this point. The statements made to the figures are then to reverse accordingly.
