Definitions
- the invention relates to a device for punching, embossing and / or shaping flat elements with a base body with a table and support for the flat element and with a base plate carrying a tool stamp, which with the aid of a drive for performing the machining process on the support in a processing station for the engagement of the tool stamp with the support and away from the support.
- Such devices are used to punch or deform flat semi-finished products such as sheets, strips and blanks in a continuous process.
- These sheets, strips, plates or blanks, called flat elements can consist of different materials, for example cardboard, laminated cardboard material, multilayer material, sheet metal.
- Previously known devices similar to the type mentioned at the outset are provided with a direct hydraulic or pneumatic drive with a cylinder acting on a punching tool.
- the object of the invention is therefore to provide a device of the type mentioned at the outset, with which a large number of very short, high-precision punching strokes in succession are possible for introducing punch holes or embossings.
- a device of the type mentioned at the outset with which a large number of very short, high-precision punching strokes in succession are possible for introducing punch holes or embossings.
- fast moving flat elements short downtimes and thus short cycle times, and possibly even short machining strokes, are to be achieved.
- transmission means are coupled between the drive and the base plate, which transfer the base plate from a rest position, in which the tool stamp is disengaged from the support, essentially without pressure build-up until shortly before the machining position Move a short distance into the machining position while generating a high pressure between the base plate and the flat element and move the base plate back into the rest position when the drive continues to operate over areas essentially without pressure build-up.
- holes can be punched and / or embossed in flat semi-finished products.
- the flat semi-finished products are generally referred to here as flat elements.
- the invention is based on the basic idea of driving the tool stamp attached to the base plate in accordance with a specific movement pattern. This is ultimately about the movement of the tool stamp towards or away from the support which holds the flat element. In the case of punching, a hole can be provided in the support, so that the tool stamp punches through the flat element into this hole in the support. Similar considerations apply to embossing.
- the movement pattern itself should follow the principle of moving the tool stamp (and thus the base plate) towards or away from the machining position without substantial pressure build-up, with a higher movement speed being provided here. If, on the other hand, the tool stamp arrives in the machining position, the movement should only take place over a short distance, but with the generation of high pressure.
- This movement pattern is achieved via an intermediate transmission medium between the drive and the base plate.
- the tool stamp is advantageously kept absolutely parallel to the plane of the flat element over the entire cutting depth or embossing depth in this processing. According to the invention, this advantageously achieves a flat, smooth, sliding and non-jerky course of force. With the invention, those impacts that occur in conventional devices when the full punching force is applied in the linear direction can be avoided.
- the invention provides that the axis of the drive is perpendicular to the axis of the tool stamp; whereas in another embodiment the axis of the drive is parallel to the axis of the tool stamp.
- the drive can be a pressure sensor with cylinder and piston, the piston movement of which in one embodiment runs parallel to the conveying direction of the flat element. Since the axis of the tool stamp is arranged perpendicular to the plane of the flat element, the drive axis is then perpendicular to the axis of the tool stamp.
- the drive is a motor, the axis of rotation of which is parallel to that of the tool stamp; in a special embodiment, the axes even coincide.
- the transmission means have at least one rotary lever which can be pivoted about a fixed pivot point. Such a structure is robust and precise.
- Another preferred embodiment, in which the axis of the drive is perpendicular to the axis of the tool stamp, is characterized in that the linear direction of movement of the base plate is predetermined by a column guide acting between the base body and the base plate and that the drive is in its perpendicular to it Axis (of the drive) has linearly oscillating drive means.
- Such an oscillating drive means can be, for example, a pneumatic or hydraulic cylinder with a reciprocating piston.
- the piston rod can be seen as such a linear, oscillating drive means, through which one can think the axis of the drive is laid.
- the axis of the tool stamp then runs perpendicular to this.
- the column guide enables precise angular holding and exact machining, for example punching or embossing.
- Such an embodiment is further developed according to the invention in that a long rotary lever is pivotable about a pivot point fixed to the base body and is coupled at one end via a toggle joint to one end of a short pivot lever, the other end of which is coupled to the base plate via a toggle lever bearing ,
- This mechanical structure provides a dead center in a certain position of the long rotary lever and the short pivot lever, and this results in the greatest force effects in the vicinity of this dead center, taking into account the basic idea mentioned above.
- this is achieved by the long path of the linearly oscillating drive means, with the advantage of a short path of the machining tool, for example tool stamps.
- the drive can have a pneumatic cylinder or a hydraulic cylinder.
- the long rotary lever, coupled with the short swivel lever can be seen as a kinematic system, which works in such a way that the base plate is a machining operation, for example, both in the direction of rotation of the long rotary lever in the counterclockwise direction and in the clockwise direction Punching process.
- the principle according to the invention can be clearly realized, namely that the tool stamp is first brought close to the flat element with a large and rapid stroke and low force and then the machining is carried out with a short distance and great force; after which, in turn, the tool stamp is removed or moved away from the flat element with a large and rapid stroke and low force.
- At least one roller is rotatably attached to the base plate, which roller is guided against at least one curve, which has a course at least at one point with a component parallel to the axis of the tool stamp. If the curve had no location with such a component parallel to the axis of the tool stamp, the roller running against the curve could not move the roller or the base plate connected to it when the curve was moved relative to the roller. If a short and powerful stroke in the direction of the axis of the tool stamp is desired to carry out the principle according to the invention, then the component mentioned should be provided parallel to the tool axis at the relevant point on the curve.
- the curve mentioned can be provided on an oscillating or rotating machine part which is stationary or movable, provided that only a relative movement between the roller and the curve is possible.
- the curve is provided as a transmission means on the circumference of a rotatably driven cylinder.
- the curve can be incorporated in the form of a groove.
- axial elevations on the cylinder are also possible.
- rollers are mounted rotatably on a holder of the base plate, which act against one.
- Curve for example in a groove on the circumference of the rotatable cylinder, run in such a way that, depending on the course of the curve, the base plate can be moved in an oscillating manner via the holder in the direction of the axis of the cylinder then lying, for example, in the direction of the axis of the tool stamp.
- Finding the cylinder also provided with a coaxially attached pinion, which is driven by meshing with an oscillating rack.
- Another embodiment is characterized in that the curve is provided on the rotary lever.
- Yet another advantageous embodiment of the invention provides, similar to the toothed rack, that the movement of the roller runs along a rectilinear cam bar, namely in such a way that, according to the invention, the cam is arranged on an oscillatably movable, straight cam bar.
- the drive of either the aforementioned cylinder with the groove or the above-mentioned pinion can be, for example, a rotary motor, preferably a servo motor.
- the curve can have several of the above-mentioned special locations along a full circumference of the cylinder or along the toothed rack with the course with a component parallel to the axis of the tool stamp, so that with one revolution the tool stamp at least once with the support and the flat element in Intervention comes, for example, punching or embossing, possibly even two to four times per full length or per full extent.
- a further advantageous embodiment of the invention is characterized in that the axis of the rotary lever is perpendicular to the axis of the tool stamp, which can be moved in translation and rotation relative to the rotary lever via the base plate.
- the rotary lever is a carrier of the tool stamp, possibly also the carrier of two tool stamps.
- the axis of this rotary lever is parallel to the plane of the flat element that is to be machined.
- levers and / or cam disks form a kinematic system and hold the tool punch over the entire stroke movement of the punch, that is to say when moving towards the support and also when withdrawing from it, always absolutely parallel to the flat element.
- the rotary lever With this counter tool too, the rotary lever, the tool carrier, holds the tool stamp absolutely parallel to the flat element.
- the speed of rotation of the rotary lever can be set by controlling the drive motor so that the tool stamp only comes into engagement again when the correct distance from the machining point to the machining point (for example, from punching to hole) was covered by a moving flat element.
- the flat element can also be imagined as a moving strip of material, with processing on this strip being carried out in a continuous and economical manner. ren can be made. This is achieved with the measures according to the invention due to the very short downtimes and the equally short machining process with a short stroke.
- the new device allows extremely short cycle times and the processing of strips or webs as flat semi-finished products as they pass through. This also applies to very fast moving belts and webs.

- the first embodiment of the device here a device for punching a horizontally continuous metal strip, is shown in FIGS. 1 to 3.
- a holder 2 for a cylinder pivot bearing 3 is fastened on a base body 1 of the punching device.
- a pneumatic cylinder 4, which is selected here as the drive, is mounted on the base body 1 via the cylinder pivot bearing.
- a piston rod 5 is mounted such that it can move linearly so that a fork head 6 is attached to the free end of the piston rod 5 and, depending on the control of the pneumatic cylinder 4, in the outward direction 7 (arrow) or inward direction 8 (arrow ) is movable.
- a long rotary lever 9 is articulated to the upper bearing 10 of the rotary lever 9.
- the long rotary lever 9 can be pivoted about its pivot point 11 fixed with the base body 1 with the aid of the drive 4, 5.
- a recess 12 is located in the base body 1 for this pivoting.
- the latter At its end of the long rotary lever 9 opposite the upper bearing 10, the latter has a toggle joint 13 to which a short pivot lever 14 is articulated.
- the latter is rotatably connected via its lower toggle lever bearing 15, which is provided at the other end of the pivoting lever 14, to a holder 16 which is fixedly attached to a base plate 17.
- this base plate 17 is horizontal, that is to say at a distance and parallel to a table 18 which is also fastened to the base body 1. While the latter is stationary, the base plate 17 can be moved in translation upwards in the upward direction 19 or downward direction 20. This movement is carried out by the drive with the pneumatic cylinder 4 and the piston rod 5. So that the base plate 17 remains parallel to the horizontal plane of the table, a column guide 21 is provided, the structure of which is clearly visible from FIGS.
- a plate-like support 26 is fastened on the table 18, in the center of which a hole 27 is made with ground upper edges 28, the dimensions of which are matched with precision to the outer edge of the tool stamp 24 in a manner known per se.
- the metal strip 29, which lies between the support 26 and the tool stamp 24, is indicated only schematically above the support 26.
- FIG. 1 shows the rest position I of the base plate 17, in which the tool stamp 24 lies at a sufficient distance above the metal band 29 without being in engagement with the latter.
- the drive moves the piston rod 5 in the outward direction 7
- the long rotary lever 9 is moved from the position shown in FIG. 1 to the processing position shown in FIG. 2.
- the toggle lever dynamics initially result in a longitudinal movement of the holder 16 with the base plate 17 in the downward direction 20 (punching direction) quickly and without pressure build-up.
- the toggle joint 13 is in the dead center area.
- the movement of the long rotary lever 9 shortly before the machining position II, in the same and shortly thereafter causes only a small stroke with very great force.
- the processing is punching out, and here the punched-out perforated disk 30 is shown schematically. If the piston rod 5 is moved further in the outward direction 7, the long rotary lever 9 rotates further about its pivot point 11 in the counterclockwise direction.
- FIG. 5 shows, analogously to FIG. 2, the position of the rotary lever 9, which has brought the tool stamp 24 to the bottom dead center. To the left of this figure, a detailed section through the cam-shaped rotary lever 9 can be seen.
- the lever 9 When the lever 9 is milled out, it bears the holder 16 shown broken off in the middle on the one hand via a lower bolt 34 and, on the other hand, carries the roller 33 or 33 on the outside '. This ensures play-free guidance in the vertical direction above and below. In addition, the movement in the downward direction 20 or upward direction 19 can be transmitted without play.
- FIG. 6 shows in this second embodiment the position III of the base plate 17 when the rotary lever 9 is pivoted farthest in the counterclockwise direction around the fixed pivot point 11, i.e. the piston rod 5 is most extended.
- the base plate was moved up out of the support 26 again. If you move the piston rod 5 in the inward direction 8 again by driving the pneumatic cylinder 4, then the pivoting lever 9 is pivoted clockwise with the base plate 17 being moved down again, the punching process and retraction until the initial rest position I of the base plate 17 two punching operations can be carried out with one reciprocating stroke.
- FIG. 7 An isometric view is shown in the left representation of FIG. 7 and a side view of a third embodiment, partly in section, is shown in the right representation of FIG. From the right side view, one can see the holder 16 of the base plate 17, broken off in the form of a fork. Rollers 33 and 33 'are again rotatably mounted on axle bolts 34 on this holder 16. These rollers 33, 33 'run in a curved cylinder 35. A double curve 31, 31' is milled in the circumference of which, approximately in the central region of its axis 36. The rollers 33, 33 'just fit into this groove.
- the curves 31, 31 ' have a course at the point labeled A with a component parallel to the axis 25 of the tool stamp 24, this axis running parallel to the axis 36.
- the axle shaft 34 of the rollers 33 runs essentially along a horizontal plane which is to be thought of as perpendicular to the axis 36.
- the axis pin 34 moves from this plane, however, corresponding to a component in the direction of the axis 36 and thus also the axis 25 of the tool stamp 24, so that the analog Movement in the upward direction 19 or downward direction 20 is ensured for machining by means of the tool stamp 24.
- the cam cylinder 35 is rotated in the circumferential direction 37 about the axis 36, while the axle bolt 34 with the holder 16 and the base plate 17 are only moved in the upward (19) and downward direction (20) can.
- the axis of the drive can either run perpendicular or parallel to the axis 36.
- the drive is preferably a servo motor.
- the course of the curve 31 is selected such that the tool stamp 24 can be moved very quickly towards the metal strip 29 by the steep point A with the directional component parallel to the axis 25 of the tool stamp 24.
- the curve 31 (or 31 ') becomes ever flatter, similar to an oblique-angled plane, so that with a short punching path in the downward direction 20, the material, for example the metal strip 29, can be acted on with great force.
- the flat element here the metal strip 29, can be moved past the tool stamp 24 either stationary or at an intermittent speed on the support 26.
- a moving belt is also stopped in the machining position and started again after the machining process.
- FIG. 8 shows a fourth embodiment in which the cam cylinder 35 is constructed and driven in a similar manner.
- the rotary cylinder 35 according to FIG. 8 is driven via a reciprocating toothed rack 38, the translational back and forth movement of which is indicated by 39 by the double arrow.
- This rack 38 meshes with a pinion 39, which is fixed on the axis 36 of the cam cylinder 35.
- a hydraulic or pneumatic pressure transmitter can act as a drive on the rack 38.
- the other functions are analogous to those in FIG. 7.
- FIG. 9 shows a further fifth embodiment of a drive, in which a pressure transmitter of some kind acts on the cam rod 40 shown in FIG. Slide bearings 41 are indicated, which ensure precise and easy mounting for the back and forth movement according to double arrow 42.
- a pair of curves 31, 31 ' is milled in each groove, so that there is again a curve profile which has several points A, at which the respective curve with a component parallel to the axis 25 of the tool stamp 24, not shown here, runs.
- This axis 25 runs through the holder 16 and vertically through the axle bolt 34 of the roller 33 (of the pair of rollers).
- the double arrow shown in FIG. 9 therefore also lies in the axis 25 of the tool stamp 24 or parallel to it. Holding the holder 16 in the translation direction 42 parallel to this. Hold the holder 16 in the translation direction 42 as shown
- Double arrow in Figure 9 preferably fixed in a horizontal plane and if the holder 16 is only allowed a translational up and down movement according to arrow 43 for an upward direction 19 and a downward direction 20, then the movement of the cam rod 40 in the direction of the double arrow 42 produces a linear up and down movement of the holder 16 in the direction of the double arrow 43.
- the drive of the cam rod in the direction of the double arrow 42 can again be generated by different motors, cylinders and the like.
- FIG. 10 shows a sixth embodiment of the device according to the invention for the special processing of a punching with the aid of the tool stamp 24 in cooperation with the support 26 acting as a counter-holder.
- a metal strip 29 rests on a support 26 which is interrupted in the processing station and has a flat, horizontal surface. which is moved with intermittent movement in conveying direction 44 (from right to left in FIG. 10). Whenever the metal strip 29 is at a standstill, the point of the strip to be machined is in the machining position and under the tool stamp 24 or above the ring-shaped support 26. This is a ring-shaped tool that is ground at least on the inside edge and at the top and acts as a counterhold to the tool stamp 24.
- the latter can be moved translationally in the direction of the longitudinal central axis 32 of the rotary lever 9, which is vertical in the processing position as shown in FIG. 10, towards the metal strip 29, piercing it and penetrating into the circular opening in the interior of the annular support 26, that the punched-out perforated disk 30 can fall out during the punching process.
- the upper rotary lever 9 can be rotated about a likewise horizontal axis 45 which runs perpendicular to the conveying direction 44 of the metal strip 29.
- the rotary lever 9 looks rectangular with rounded corners and carries a two-armed lever 46 on each of the two end faces which are radially outward towards the axis 45 and which is firmly connected to the base plate 17 acting as a tool holder.
- the two-armed lever 46 and the base plate 17 can be pivoted about a pivot axis 47 and can also be moved linearly in the direction of the longitudinal central axis 32.
- the pivot axis runs parallel to the axis of rotation 45 of the rotary lever 9 and lies in the longitudinal central axis 32 of the rotary lever 9.
- the parts which can be moved translationally and rotationally relative to the rotary lever 9, namely the two-armed lever 46 and the base plate 17, are provided by a stationary preferably routed on the base body in a groove-like manner and controlled thereby.
- the two-armed lever 46 is V-shaped in the plan view of FIG. 10, and at the free ends of the V-shaped, diverging extending levers, the rollers 33 are articulated via axle bolts 48, which drive against the curve mentioned and are controlled by it.
- the direction of rotation of the rotary lever 9 is illustrated by the two curved arrows 49, so that one can easily imagine that the left roller 33 on the two-armed lever 46 is the front roller in the running direction and is the first to enter the stationary control cam when the rotary lever 9 enters the machining position from an oblique position before it has reached the position in FIG. 10.
- the tool stamp moves in this way with great rotational speed over a long way into the position of FIG. 10. Shortly before reaching this position, the path speed of the rotating lever 9 and the conveying speed of the metal strip 29 in the direction 44 are the same. In addition, the front face of the tool stamp 24 is held precisely parallel to the flat surface of the metal strip 29 shortly before the machining position is reached. In a short way under high pressure build-up, the base plate 17 with the tool stamp 24 can then be moved translationally in the direction of the longitudinal central axis 32 downward toward the support 26 in order to carry out the processing (for example stamping). In the punching area, the end faces of the tool stamp 24 are kept absolutely parallel to the band 29. f
- Such a rotary lever is likewise arranged on the side opposite the upper rotary lever 9 and rotatable about an axis corresponding to the axis 45.
- the ratios of the movements and controls are in mirror image the same as those for the upper rotary lever 9 as described above.
- the lower base plate has the mentioned support 26 so that the tool stamp 24 can be pressed linearly into the hole of this support 26 and can be linearly pulled out again in the opposite direction.
- the two-armed levers 46 leave the curves and can then be moved on without guidance.
- two tool punches are arranged on sides diametrically opposite with respect to the axis 45.
- the rotary lever can also be designed for more tools, for example four, six or even three and five tool punches with a base plate. LIST OF REFERENCE NUMERALS
