Definitions
- the present invention is concerned with a device for profile bending of metal profiles (especially of hollow profiles) according to the preamble of Claim 1, and with a method for their operation.
- Such a device is for example with the object EP-A-492 211 has become known.
- the core of the well-known The method for operating this device is that two opposing rollers form a nip through which the profile to be bent is pushed through by a pushing force, ie the bend then due to the rotary drive of each other opposite bending rollers in connection with the acting Thrust occurs.
- other opposite leadership roles present, which a bulge and buckling of the to be bent Should prevent profiles.
- Thrust station must be used, which is suitable by means of high shear forces (in the range of several tons) Profile between the rotating driven bending rollers push to achieve a corresponding reshaping.
- the object of the present invention is therefore a Method and device for bending metal hollow profiles according to the preamble of claim 1 so to further develop a universal machine, with which it is possible to press individual bending stations against each other replace, completely remove or otherwise arrange with the aim of a universally usable To reach bending machine.
- An essential feature of the invention is that the entire Roll bending station consists of individual roll stations, from which each role station has at least one role that attaches itself to the profile to be bent and that everyone A different bending task is assigned to the roller station and that each roller station is modularly interchangeable and adjustable and removable on a common Machine body is arranged.
- a thorn can Supporting the profile can be provided on the inside.
- the core of the invention is therefore the modular structure, where one Row of roller stations adjustable and deliverable in the common machine body are arranged, and are preferred the individual roller stations on so-called X / Y slides arranged adjustable, it for individual Roll stations are sufficient, only one infeed in the Y direction to allow while adjusting in the X direction can be omitted.
- a so-called roll bending (left or right bending) by realizing that on one side of the in the X-Y direction to bend hollow profile side by side and a bending station, a mutually adjustable Guiding and rolling station and a support station arranged are.
- Each of the stations mentioned has at least one role on, leaving it open whether all rollers are driven in rotation are or not.
- the role of the bending station (Bending roller) is not driven in rotation while the rolling and rotating the guide roller of the guide and rolling station is driven and that the support roller of the support station is also not driven in rotation.
- Middle roller station which consists of a single, rotatably driven center roller, which is interchangeable and by other rolls of different diameters and Profile shapes can be replaced. This interchangeability applies otherwise also for the others - just mentioned above - Roll.
- a so-called core-roll bending is provided, again on the one side of the profile is two or three roller stations create, only the presence of two Roller stations is preferred, one of which is a roller station the guiding and rolling station is and the other roller station the support station, and that these two stations a core bending station is arranged opposite, which has a rotatably driven core, on the rotatably Clamping head is attached, which is the front, free end of the bends profile.
- the profile is under one Torque by means of a pulling force counteracting the rotation bent around the core, the core rotating (Winding process), the aforementioned roll stations ensure that the profile clean in the bending area to the core is pressed.
- roller stations mentioned several slide shoes are arranged to prevent the profile to be bent between the above Roller stations bulge or deform.
- an important one Advantage of a preferred embodiment of the invention is that practically only two mutually opposite rotating driven rollers are present, namely the rotatingly driven role of Guiding and rolling station, which is usually the middle role which is three roller stations arranged on one side, opposite one during this guiding and rolling station rotating center roller of the center roller station opposite. Because these two roles of each other opposite stations are driven in rotation, can an expensive pushing device can be dispensed with, as with the subject of the older EP 492 211 B1 was described. at this elaborately designed push station extraordinary thrust in the range of several tons be applied, what with a correspondingly high Machine effort was connected. Likewise with EP 492 211 B1 provided that not only two rotating driven rollers were present, but that more than two rotating driven Roles were in place, with a correspondingly higher one Machine effort was connected.
- a carriage is also used present, which is at the back of the profile to be bent creates the in a sled run on the machine body is driven displaceably.
- This sled can, however just run along, so that a thrust towards it bending profile is not exercised.
- sledge is an exact measurement over a straight Measuring section for determining the length of the Hollow profile possible.
- the said carriage is otherwise intended to occasionally the profile in the opposite direction to his Direction of transport can be pulled with the carriage, d. H. it becomes a compared to the drive of the roller bending stations Tractive force exerted on the profile to be bent, which is special is the case with so-called core-roll bending.
- the said sled also serves to make it easier Threading a hollow profile to be bent into the Roller bending stations, this slide then in the The threading position moves close to the roller bending station and the hollow profile to be bent from the outlet side into the Roll bending station is introduced, is pushed through there and is caught by the sled, causing it to move backwards is pulled into its initial bending position.
- the machine according to the invention consists essentially of a roller bending station designated overall by 1, which consists of a number of roller stations.
- a roller bending station designated overall by 1, which consists of a number of roller stations.
- the roll bending station 1 from one end to the bent profile 4 Bending station 17, an adjoining one, approximately in the middle arranged guide and rolling station 15 and from a downward support station 16.

- the X setting of the Stations 15 - 17 in total depend on the profile size the shift in the Y direction is necessary to the To optimally design the bending process.
- a bending roller 27 is assigned to the bending station 17, the guiding and rolling station is a rolling and Guide roller 28 assigned and the support station 16 is here assigned a support roller 29.
- spindles 19 a, 19 b, 19 c are the individual Stations 15 - 17 adjustable and lockable in the X direction educated.
- the adjustment drives for the adjustment of the individual rollers 27 to 29 or stations 15-17 in the Y direction are not shown in detail. This happens e.g. B. about Hydraulic igniter or also via spindle drives.
- the center roller station 11 is also modular constructed and attached to the machine body 18, a Drive 23 for the rotary movement of the center roller 13 about the axis 12 is provided.
- FIG. 3 shows an enlarged view of FIG Representation of the bending process when bending the profile to the left.
- both the Total distance 31 between the modules Stations 15-17 are adjustable and lockable, and further it is important that the distance 35 between the individual Stations 15 - 17 are also individually adjustable.
- the distance adjustment 20 takes place in the X direction - as before specified - with the help of the individual actuatable spindles 19 a, 19 c.
- the center roller 13 consists of the embodiment shown a roll of smaller diameter between two discs 14 (Fig. 1, 2) larger diameter is arranged, the Slice the profile to be bent from above and below at least partially overlap and the diameter of the center roll 13 on the side of the profile to be bent.
- a pressure 33 of the middle rolling and guide roller 28 of about 50 kN provided with a profile cross section in the range between 40 up to 220 mm.
- Figure 3 also shows that a relatively small central role 13 by a correspondingly larger center roller 13 ' is interchangeable. This will result in better bending qualities achieved.
- Figure 4 shows, moreover, that with such Arrangement of very tight radii with profile cross sections of z. B. 40 mm can be bent.
- Figure 5 shows the modular structure, where compared to FIG. 2 shows that only the machine body 18 the module-like stations 15 - 17 of one brought to the other side and also the Middle roller station 11 on the opposite side was repositioned.
- a carriage 24 for the Bending station 17 is provided, a slide 25 for the Guide and rolling station 15 and a carriage 26 for the Support station 16. All the slides mentioned are in the X-Y direction adjustable and lockable.
- the various Roll the different stations in the direction of arrows 32 and 34 be adjustable.
- the stations mentioned also in the direction of arrow 38 (Y direction) are adjustable, it being in the sufficient embodiment shown, the middle station 11th only adjustable in the Y direction (infeed direction 38) train while not adjusting in the X direction is required.
- the invention does not apply to this limited; the invention can also be provided that the center roller station 11 adjustable in X and Y and is designed to be detectable.
- Figure 8 shows in comparison to Figure 7 that it is due to the precisely performed bending process it is not only possible such a frame with straight profile sections bend, but there can also be curved profile sections 43 may also be provided.
- Figure 9 shows in comparison to Figure 8 that at a corresponding setting of the individual roller stations 15 - 17 in connection with the center roller station 11 Full circle (curved profile section 44) can be bent.
- roller stations are adjustable and otherwise, a print 33 in each of the drawn Direction of arrow from the middle rolling and guide roller 28 the profile to be bent is exercised.
- FIGS A so-called alternate roll bending is shown in FIGS shown, it being apparent that due to the given the modular construction, the middle roller station 11 has been removed and another module instead exists from stations 15 - 17 of one, on the opposite Side is arranged, as in Figures 10 and 11th is shown. After it is the same modular parts are the added modules with a prime characterized.
- Figure 12 shows the more advanced Alternating bending process, whereby it can be seen that radii with different centers 45 a, b, c can be bent.
- rollers 27 ', 29' are definitely necessary because of these Roll the action forces that arise during the bending process have to record.
- FIGS A so-called core-roll bending is now shown in FIGS described in more detail.
- the core bending station 46 consists of an X-slide 49 and a Y-carriage 48, both in the directions mentioned can be set separately from one another and which can be used together on the Machine bed 47 are attached, which is modular to the Machine body 18 is attached.
- FIGS 15 and 16 show further details of the Contraption.
- a sliding and Guide shoe 54 is arranged, which is frictionally attached to the creates one side of the profile and thus for a high Bending quality ensures because it is the profile 4 to be bent presses the outer periphery of the rotatable core 50.
- the bending is carried out in the area of the axis of the Roller 28, wherein additionally a pressure in the direction of arrow 33 is applied. This is particularly the case in FIG. 16 detect.
- This pressure in turn has a rolling effect on this side of the profile while the opposite side is under less rolling work on the outer circumference of the core.
- the carriage 3 not only runs along and serves as a measuring system, but it can also be used in the arrow direction 51 shown is driven displaceably be a tensile force in the direction of arrow 51 on the free end of the profile to be bent.
- the carriage therefore exerts the tractive force described on the total length of the profile to be bent in the connection area between the carriage 3 and the clamping head 52.
- the profile is thus stretched by the tensile force described.
- the selection process described by the roller 28 and the described stretching process by the carriage 3 favors the Bending accuracy with the least possible deflection of the bending profile.
- Figures 17 and 18 show the use of a different core 53, but otherwise the same explanations apply that given with reference to Figures 15 and 16.
- the Core in the direction of arrow 30 and in the opposite direction drivable.
- the first Corner 60 has already been bent.
- the clamping head 52 then opens, swings back its starting position according to FIG. 17, closes,
- the carriage 3 is fed in the opposite direction to drawn arrow direction 51 on the profile up to Beginning of corner 61; this is then according to FIG. 18 bent.
- This process then becomes 62 until the last corner repeated, which was just bent in Figure 18.
- FIG. 19 shows bending as a further exemplary embodiment around a circular core 58, with the same explanations apply as above.
- the Clamping head 52 opens, travels a part of the way again closes and the arch to 360 ° and beyond rotating core 58 continues to bend, being inclined Contact surface that is already almost at the 360 ° bent tube over the bending station over a full circle or to bend a spiral beyond the full circle.
- this deflecting surface is shown in FIG. 19 not shown. However, it is only shown that during the bending process the clamping head 52 separated from the Core 53 is guided in the X-Y direction and optionally in Direction of arrow 57 radially to the center of rotation of core 58 is pressed.
- Invention therefore has the essential advantage that a Variety of different bending tasks with one and same machine can be fulfilled, whereby by the modular arrangement of different stations different Bending processes can be realized on one and the same Machine run off.
- the machine body can therefore also be used within the meaning of this definition 18, 18 'can be understood as a module.
- FIG. 20 shows another exemplary embodiment, that the different roles 27-29 are not necessary the individual roller station 15 - 17 to be of equal size.
- the middle rolling and guide roller 28 smaller to be trained and designed to be adjustable only in the Y direction, while the other rollers 27 and 29 in the X and Y directions are adjustable.
- roller and guide roller 28 is kept smaller the slide on which the roller is seated and so that the entire management and rolling station 15 essential be made smaller and thus the center distances the bending roller 27 and the support roller 29 to the axis of Center roll 13 can be greatly reduced.
- this embodiment shows that the Carriage 3 not only adjustable and drivable in the X direction is, it can also be adjusted in the Y direction be trained.
- mandrel station 5 which is also in the Y direction is adjustable and in the X direction is adjustable.
