Definitions

  • the invention relates to a bending machine with variable roll or shaft geometry, in particular a roll plate bending machine with at least three rolls.
  • the invention relates to a bending machine, in particular a round bending machine according to the preamble of claim 1.
  • the bending of large sheets into shaped parts is typically carried out with sheet metal bending machines, to which a sheet is fed from one side, and which force the sheet into a desired shape as precisely as possible.
  • the action of force and the parameters of the sheet determine the degree of deformation.
  • a sheet that is fed in essentially has the temperature of its surroundings, that is to say that the sheet metal bending process is a cold deformation. Even if the embodiments of the invention described below start from such a cold sheet, the method described and the corresponding control system should not be limited to this. The method described can also be used for a heated or hot sheet.
  • the round bending machines described here work according to the known method of roll rounding and have at least three rolls.
  • the sheet to be bent can be clamped between two rolls, an upper and a lower roll, at least one of which is motor-driven, so that a sheet clamped between these rolls can be moved by rotating the rolls.
  • a bending force is exerted on the sheet by means of a further roller, a side roller.
  • the sheet can be moved between the rolls of the bending machine and over the side roll by means of the at least one driven roll such that the sheet is bent.
  • the machine can only have only the top roller and a first and a second side roller.
  • a sheet to be bent is then over the first side roll, which can also be referred to as a secondary roller, is guided below the top roller and then over the second side roller, the second side roller being positioned such that the sheet is bent.
  • the drive of the sheet can be designed as desired.
  • the invention described below is independent of whether the bending machine has an upper and / or lower roll of the machine. It can be used both in a bending machine with an upper and lower roller or in a machine which has only one upper or lower roller.
  • the degree of deformation during a bending process depends on a large number of parameters.
  • the properties of the sheet to be bent for example the sheet thickness and the deformability and toughness, have a considerable influence on the radius of the bent sheet.
  • the geometry of the rolls relative to one another and the geometric dimensions of the rolls arranged in the bending direction themselves determine the smallest possible bending radius during bending.
  • the theoretically smallest possible bending radius is typically the diameter of the top roller or the roller around the radius of which the sheet is bent.
  • the sheet to be bent must be guided in such a way that it is guided as closely as possible to the corresponding roll, for example when the sheet is bent by the radius of the top roll, on this roll. Accordingly, the geometry of the rolls must be adapted to one another in accordance with the desired bending radii and depending on the thickness of the sheet.
  • a side roller can be held in a rocker arm, which is fixed at one end in the frame of a bending machine and is held at its other end by a hydraulic cylinder.
  • the position of the rocker and thus the position of the side roller held by it can thus be changed via the position of the hydraulic cylinder.
  • another actuator for example a threaded spindle, can be used.
  • Such rolling machines nevertheless have the disadvantage that the movable side roller can only be moved within narrow limits, since one end of the rocker is fixed. Replacing the side roller or changing the position of the fixed end of the rocker is associated with considerable effort.
  • the DE 36 15 771 A1 describes a method and an apparatus for the round bending of sheet metal with an upper and two lower rolls, wherein a roll nip alternately between the upper and one lower roll and between the upper and the other lower roll set a roll nip through which the sheet to be bent is passed one after the other.
  • Both lower rollers are each mounted in rockers, the respective rocker is pivotally mounted about a fixed axis and the position of the lower rollers can be adjusted by pivoting the respective rockers by motor.
  • Figure 1 shows a perspective view of a bending machine 1 with an upper roller 2, a lower roller 3 and a side roller 4.
  • at least the upper roller 2 or the lower roller 3 is motor-driven, so that a sheet to be bent (not shown in the figure), which is between the upper - And the lower roller is clamped, can be moved by the upper or lower roller in the direction of the at least one side roller 4.
  • a sheet clamped between the upper and lower rolls can be moved in the direction of the side roll 4 and guided over the side roll 4, the sheet being bent depending on the geometric arrangement of the side roll.
  • Figure 1 it should be noted that only one side of the suspension of the rollers is shown in the illustration, in fact the rollers are supported accordingly at their respective two ends.
  • the bending machine is typically set up so that the distance between the upper and lower rolls can be changed so that the distance between these two rolls can be adapted to the thickness of the sheet, i.e. at least one roller can be moved so that a sheet can be clamped between these two rollers and moved by rotating the rollers.
  • the three points necessary for bending the sheet are realized in the embodiment described here by the upper and lower rollers 2, 3 and the side roller. Depending on the lower roller pressure, which is set between the upper and lower rollers, the bending lever adjusts itself when the side roller 4 is fed. In the alternative embodiment already mentioned, the three points necessary for the bending are realized by the first and second side rollers and the top roller.
  • the side roller 4 is held in a rocker 5 at at least one of its two ends.
  • This mounting of the side roller 4 in the rocker 5 can be a bearing that allows the rotation of the side roller 4, i.e. the side roller is mounted in a corresponding bearing, for example a slide or ball or roller bearing.
  • the swing arm 5 is as follows and with reference to FIG Figures 2 will be described in more detail, held at its first end 5a on a support element and fixed at its second end 5b pivotably and releasably with respect to the position of the top roller.
  • the suspension point of the side roller 4 is geometrically placed between the first and second ends of the rocker 5.
  • the rocker is held in a support element 6, the holder allowing the rocker to rotate relative to the support element 6.
  • a holder can be achieved by means of a connecting bolt, the bolt functioning as an axis of rotation.
  • the rocker is detachably fixed to the bending machine 1, the fixing allowing the rocker 5 to rotate about the fixing point at its second end 5b.
  • Such fixing of the rocker arm 5 can be achieved in one embodiment by means of a combination of bores and bolts, a (working) bolt 7 being guided through a bore in the rocker arm and a bore in (a housing part) of the bending machine 1, so that the Plug pin determines the position of the rocker 5 with respect to the upper roller and the lower roller, at the same time enables a rotational movement of the rocker around this fixing point, but can still be released relatively easily, so that the connection between rocker 5 and the frame of the bending machine can be solved.
  • the bolt 7 can be easily released when the side roller 4 does not exert any force on the bolt.
  • the support element 6 supports the rocker 5 at its first end.
  • the support element 6 is rotatably connected to the rocker 5 and is also rotatably or pivotally mounted at its other end, for example with a bolt connection, the bolt simultaneously forming the axis of rotation.
  • the length of the support element is designed to be movable, so that the support element 6 can rotate or pivot the rocker 5 about the (working) bolt at the second end of the rocker.
  • the support element can be a hydraulic cylinder or the like, for example a threaded spindle, so that the position of the rocker 5 can be adjusted by means of the support 6. In this way, the position of the rocker 5 and thus the position of the side roller 4 held by the rocker 5 can be pivoted so that the position of the side roller 4 can be adjusted relative to the top and bottom rollers.
  • the geometric arrangement of the rollers can be changed in this way, ie the side roller 4 can be moved closer to the top and bottom rollers 2, 3, so that a small bending radius can be set.
  • the rocker 5 can be pivoted so that the side roller is placed further away from the top and bottom rollers, so that a larger bending radius can be set.
  • Figure 2A shows a front view of the bending machine 1 with the upper and lower rollers 2, 3 and the side roller 4, which is supported by the rocker 5.
  • the embodiment shown here comprises the three rollers mentioned above.
  • further embodiments can have one or more further side or auxiliary rollers (not shown here).
  • the magnification A in Figure 2A shows the side roller 4 and the rocker 5, wherein the support element 6 is set so that the rocker 5 is pivoted outwards to the maximum, ie the distance of the side roller 4 from the upper and lower rollers is maximal with the position of the mounting of the rocker 5.
  • the first end 5a of the rocker can be connected to the support element 6 by means of a bolt.
  • the second end of the rocker 5 is fixed with a bolt in the support structure of the bending machine 1, the support structure designating that section of the bending machine which is provided for receiving the bolt and thus for receiving the transmitted forces.
  • the supporting structure can thus be an integral part of the bending machine 1, alternatively it can be a separate machine part.
  • the rocker 5 can be pivoted by adjusting the length of the support element 6, the rocker rotating about the bolt 7 at the other end 5b.
  • the bolt 7 is guided through a bore of the rocker arm 5 and engages in a supporting structure of the bending machine 1, which absorbs the force transmitted by the bolt 7 and thus carries the rocker arm 5 and the side roller 4.
  • the rocker arm 5 has a bore 8a for receiving an interchangeable bolt 10 (not shown here) and the supporting structure of the bending machine 1 has a corresponding bore 8b. These two bores are provided and designed accordingly that an interchangeable bolt is guided through the bore 8a into the bore 8b, which can absorb the force of the rocker 5.
  • the force to be absorbed is essentially the weight force that has to be temporarily absorbed in the pivoting process described below, the bending machine not being operated in the productive sense during the pivoting process.
  • the interchangeable bolt 10 therefore does not have to absorb the forces occurring during a bending process, but only the weight forces and can therefore be dimensioned correspondingly smaller.
  • the frame of the bending machine which absorbs the forces of the (working) bolt 7 and the interchangeable bolt, has a further bore 9, which is provided for receiving the (working) bolt 7.
  • Figure 2B and in particular the section B shows a position of the rocker 5, in which the rocker, for example, from the in Figure 2A position shown was pivoted so that the bore 8a in the rocker 5 is congruent with the bore 8b.
  • the length of the support element was set accordingly, ie in the present case the hydraulic cylinder was extended so far that the rocker 5 was rotated / pivoted about the bolt 7 to such an extent that the bores 8a and 8b are congruent, so that a change bolt 10 can be placed therein.
  • the interchangeable bolt 10 can be removed, so that only the interchangeable bolt carries the rocker 5 and the rocker is thus pivoted or pivotable about the interchangeable bolt 10.
  • the interchangeable bolt can be smaller, in particular with a smaller diameter, since it only has to bear the weight of the rocker 5 together with the side roller 4 stored therein.
  • the position of the rocker 5 can now be changed by suitably adjusting the support element 6, in particular pivoted about the change pin 10.
  • the rocker 5, here by suitably shortening the support element 6, can be pivoted, here by approximately 53 °, that the bore in the rocker 5 for the bolt 7 is congruent with the bore 9 in the frame of the bending machine 1.
  • FIG. 2E shows the rocker 5 in the same position as in FIG Figure 2D , wherein the (working) bolt is placed in the rocker arm 5 and the bore 9, so that the bolt 7 carries the rocker arm 5 and the side roller 4.
  • both the bolt 7 and the interchangeable bolt 10 are placed in the rocker arm and the supporting structure of the bending machine 1, so that the rocker arm 5 is fixed by both bolts and is therefore not pivotable.
  • the interchangeable bolt 10 can be removed as soon as the bolt 7 is placed. Then the rocker 5 can be rotated or pivoted about the bolt 7. The rocker 5 has thus been pivoted from the second to a third position and has been fixed there in a rotatable or pivotable manner.
  • the rocker 5 is arranged closer to the upper and lower rollers of the bending machine, since the bore 9 is placed closer to the upper and lower rollers of the bending machine in the supporting structure.
  • the side roller 4 can be placed closer to the top and bottom rollers. In the position shown, the side roller 4 is placed closer to the top and bottom roller than in that in FIG Figure 2A shown position.
  • the placement of the rocker 5 together with the side roller 4 held therein can be changed so that the arrangement of the side roller with respect to the top and bottom roller can be changed and adjusted according to the requirements.
  • the force for pivoting and holding the rocker 5 and side roller 4 is applied via the support element 6 and the interchangeable bolt 10, so that the side roller 4 does not have to be held or raised by means of a crane or the like during the pivoting.
  • only the (working) bolt 7 and the interchangeable bolt 10 are to be placed at the respective end of the side roller, which can be carried out by hand or in any case with considerably less effort.
  • the rocker 5 is from the first position, see Figure 2A , about a second (intermediate) position, see Figure 2C , swiveled into a third position, see Figure 2F with the side roller 4 placed closer to the top and bottom rollers in the third position.
  • the side roller 4 can be pivoted in a further pivoting process from this position first into the second (intermediate) position and then back into the first position.
  • the side roller can be pivoted into one or more positions via an intermediate position, provided that corresponding bores 8b are provided for the interchangeable bolts and corresponding bores 9 for the (working) bolt.
  • the figures show an embodiment in which the side roller 4 can be arranged in two positions by means of the (working) bolt.
  • the structure of the Bending machine have further holes 8b, 9 for receiving the change and the (working) bolt 7, so that the rocker 5 can be pivoted into further positions.
  • the rocker in order to change the geometrical arrangement of the side roller 4, the rocker is pivoted by means of the support element into an intermediate position in which the rocker is held by means of interchangeable bolt 10, and from there is pivoted again into the second position by means of the support element, in which the rocker is then fixed again with the working bolt 7.
  • the rocker 5 can be fixed in a first or optionally in a second position.
  • the rocker can be brought into the second position so that it can be fixed there by other suitable means.
  • the rocker can also be lifted into the second position by means of a crane.
  • the rocker itself can have more than one receptacle for a working bolt with which the rocker can be fixed.
  • FIG 3 shows a schematic representation of an alternative embodiment of the rocker 5, which is designed in a suitable manner with other lever lengths.
  • the illustration shows a front view similar to that Figures 2 , wherein only an upper roller 2 and a side roller 4 are shown, but not a lower roller or a second side roller.
  • the rocker 5 is pivotally and detachably fixed at one end to a working bolt 7 and has a bearing for receiving a side roller 4.
  • the arrangement of the support element is chosen such that other lever ratios are set, namely in such a way that a shorter path of the support element 6, but a greater force, is necessary for a pivoting movement of the rocker 5.
  • the support element 6 is placed closer to the working bolt 7. Accordingly, the support element must be designed accordingly for the application and absorption of larger forces, but the support element need only be designed for shorter path lengths. Because the support element 6 always remains below the side roller 4 in the embodiment shown, it is protected against damage by metal sheets which do not remain ideal in the bending path. This swing arm also enables an overall more compact design. Furthermore, the inlet height becomes lower, so that the foundation on which the bending machine 1 is placed is less complex to lay out.
  • Figure 4 shows a further embodiment of a bending machine, in which a roller 4 is held in a rocker 5, and wherein the rocker can be fixed with its one end in relation to a roller in a second position.
  • Figure 4 shows a schematic plan view of a profile bending machine. in the Difference to that related to the Figures 1 to 3 Bending machine described, the bending shafts or rollers are only supported on one side in a profile bending machine. A tool can thus be plugged onto the free end of such a roller or shaft, which has the negative shape of the profile to be bent, so that the profile is held in the tool during the bending process and is therefore not damaged during the bending process.
  • This bending machine 1 like the ones described above, has an upper roller 2, which is fixed. Furthermore, the machine comprises two further rollers 3, 4, which are arranged symmetrically here and held in a respective rocker 5.
  • the rocker is fixed with its one end 5a to a movable support element 6, which is shown in the figure as a hydraulic cylinder. With the other end 5b, the rocker 5 can be fixed in a first position and in a second position, a rocker with the working bolt 7 being fixed in a first position, but being releasable, ie fixed in a first bore.
  • Figure 4 shows a definition of the rocker 5 in a respective first position.
  • each rocker arm 5 has a bore 8a and the supporting structure has corresponding bores 8b into which an interchangeable bolt can be inserted, so that a rocker arm can be rotated about the respective interchangeable bolt in the second position during the pivoting process.
  • the rocker In the second position, the rocker can then be fixed again with the working bolt 7.
  • the structure of the profile bending machine has a corresponding bore 9 for receiving the working bolt.
