Definitions
- the invention relates to a device for bending a hollow profile - preferably for the production of a hollow spacer frame for insulating glass panes, in particular filled with desiccant - with a clamping device lying approximately in the feed direction of the profile and its longitudinal extension for detecting the profile area located before the bending, with a device for Detect the leg to be bent and with an abutment for fixing the inside of the resulting bend or curvature and with a tool that can be moved on the outside of the bending point under contact pressure relative to the abutment and can be pressed against the outside of the profile, in particular in the form of at least part of the tool Pressure roller, roller or the like acting on the outside of the bend of the profile web.
- Such a device is known for example from DE-OS 33 12 764 and has proven itself in particular for profiles with sufficient wall thickness.
- the outside of the bend can be pressed on by the tool, preferably a roller or roller, are elongated and stretched, which roller can be moved back and forth with high frequency.
- the clear distance between the tool acting on the outside of the bending of the profile and the opposite abutment, at least during the bending process is at least temporarily smaller than the height of the side walls of the profile and that the crosswise to the longitudinal profile oriented dimension of the effective area of the abutment and / or the tool is less than the profile width and less than the internal clearance of the side walls of the profile.
- This combination of features and measures means that the two webs delimiting the inner and outer corners of the curved profile are clamped during the critical phase of the bend between the abutment and the tool on the one hand and between the side walls of the profile on the other hand, because of the aforementioned Dimensions the tool that acts on the outside of the profile while pressing in the outer wall of the profile that he presses between the side webs of the profile and without cracking or warping this outer wall can deform into the inner area of the profile, where a correspondingly shorter bending path is given, part of this outer wall and / or the side wall is turned inwards relative to the standing side wall and this can be approximated more or less.
- the abutment and the web acted upon by it can also be deformed somewhat between the side walls of the profile.
- a controlled bending of a very thin-walled profile can be carried out without the webs or walls being able to move in an undesired direction, but also rolling or stretches are not required or only necessary to a limited extent.
- This mutual support of the webs to be deformed in the bend region between the side walls can be achieved particularly simply in that the clear distance between the tool engaging on the outside of the bend of the Profilesa that arises and the abutment inside it, at least during the bending process, is at least temporarily at least equal to the total thickness of the both of them acted upon and parallel to them and to each other arranged webs or walls of the hollow profile or equal to the total thickness of the two webs plus a desiccant intermediate layer which is preferably reduced in its extent compared to the total height of the profile.
- the inner surfaces of the two webs can be mutually supported in a particularly expedient manner, so that these webs are clamped between the abutment and the tool and against one another during the critical phase of the bend.
- a desiccant interlayer which is preferably reduced in its extent, can be provided between these mutually facing surfaces if the hollow profile is at least partially filled with desiccant from the outset. Since desiccants generally react in a sand-like manner, a very good support of the two webs against one another can also be achieved, although a desiccant-free bend is preferred if the webs are deformed as precisely as possible into a certain position relative to the side walls and are supported directly against one another should. This is especially true when the two webs are to be brought as close as possible to the neutral fiber of the profile.
- the dimension of the abutment and / or the tool oriented transversely to the longitudinal profile of the profile is at least two wall thicknesses of the profile less than the clear internal spacing of the side walls of the profile, as a result of which the partial bending of the side walls mentioned in the bending region is performed well and can be achieved without wrinkling, especially in the presence of external hold-down devices.
- the pressure roller serving as a tool can be circumferential on its side surfaces near its circumference, which acts as a working surface, and the greater width of the pressure roller can be equal to or less than the inside clear distance of the side walls of the profile, while the narrower area of the pressure roller is approximately the width of one can correspond to the profile of the outer web area, from each of which inclined web areas fall towards the side walls.
- Such an embodiment of the device is particularly suitable for bending hollow profiles with a cross section that is at least approximately trapezoidal in the outer region.
- the sloping side wall areas then do not have to be acted upon directly by the working surface of the pressure roller in order to be able to be pressed in gradually until the outer wall area is touched by the inner web of the profile which is subjected to the abutment.
- the bevels on the side surfaces of the bending or pressure roller can have a radial width that is equal to or greater than the immersion depth of the bending roller when bending and pressing the outer web in the direction of the abutment.
- These bevels on the side surfaces of the tool have the advantage that an overly sharp bend of the outer web relative to the side webs or side walls is avoided because the inwardly bent edge web area can remain somewhat oblique with respect to the outer web.
- the abutment or the fitting serving as an abutment can be adapted to adapt to different profiles, web thicknesses, web shapes or the like. be interchangeable.
- One way of optimizing the bending process and the deformation of the inner web in particular can be that the abutment, particularly controlled, can be moved or displaced deeper into the bend than it is arranged in its starting position during the bending process.
- the increasing bend is accompanied by a greater indentation on the inside of the bend.
- claims 11, 12, 14, 16 and 17 relate in particular to a solution , in which the abutment can be pivoted in proportion to the bending process, so that its outside pulls the inside of the profile to a certain extent and especially in the exemplary embodiments in which the abutment becomes larger in the pivoting direction has the projection, practically "rolls" into the inside of the profile to be bent and into the inside bend.
- some of the claims mentioned also relate to solutions in which the abutment is pressed deeper and deeper into the inner bend approximately in proportion to the bending progress without being pivoted.
- the claims 18 to 20 relate above all to the hold-down or hold-downs, which hold the side surfaces of the hollow profile to the correct extent during the bending process and avoid warping and deformation in these areas, which could lead to a distortion of the external distance.
- Claims 21 to 24 relate to configurations which allow the use of the bending device according to the invention and in particular the compression of the inner and outer walls and webs even in the case of profiles filled with desiccant, in that the bending area is at least temporarily freed from drying agent, preferably with the aid of compressed air .
- a device designated overall by 1 in all exemplary embodiments serves for bending a hollow profile 2, it being indicated above all in FIG. 6 that this can involve the manufacture of a hollow spacer frame filled with desiccant 3 for insulating glass panes.
- the profile 2 could be bent four times if the frame is to consist of a single piece. The two profile ends could then butt and join together on one long side.
- a tensioning device 4 is provided on the device 1 for detecting the profile area located before the bend. Furthermore, the device 1 has a device 5 for detecting the leg to be bent and an abutment 6 for fixing the inside of the resulting bend or curvature. Furthermore, it is indicated in FIGS. 1, 6 and 7 and in FIGS. 8 shown in more detail that on the outside he bending point a movable under contact pressure relative to the abutment 6 and can be pressed against the outside of the profile tool, in the embodiment in the form of at least a part of the off on the side of the bend profile web 7 pressurizing roller or roller 8 is provided, which in Figures 1, 6 u. 7 is shown in different positions to illustrate their movement.
- the clear distance between the tool 8 acting on the outside of the resulting bend of the profile 2 and the abutment 6 on the inside is, as is particularly clear in FIGS. 3, 5 and 8, at least temporarily at least during the bending process, less than the height of the side walls 10 of the profile 2 and also the dimension A oriented transversely to the profile longitudinal extent is the effective, ie with the webs or walls 7 and 9 of the profile in contact surface of the abutment 6 and the corresponding dimension B of the tool 8 less than the profile width and thereby also less than the internal clearance of the side walls 10 of the profile 2.
- the walls and Crosspieces 7 and 9 are deformed during the bending by the abutment 6 and, above all, the tool 8 between the side walls 10 or, in particular, the tool 8 can be immersed between the side walls 10 and the crosspiece 7 which is particularly stressed during bending because the external crosspiece 7 is in one Bring the area of a smaller bending radius where correspondingly lower tensile forces occur.
- Figures 2 u. 3 shows that the dimension A of the abutment 6 oriented transversely to the longitudinal profile of the profile and the corresponding dimension B of the tool 8 is less than the profile width and thereby even less than the inside clearance of the side walls 10 of the profile 2. 3 even shows that the dimension A of the abutment 6 oriented transversely to the longitudinal direction of the profile and the corresponding dimension B of the tool 8 is even less than the inside clearance of the side walls 10 of the profile 2 by more than two wall thicknesses of the profile webs 10.
- the pressure roller 8 can take part of the outer wall 7 with it plunge into the profile between the side walls 10 and deform the outer wall 7 towards the inner wall 9, which in turn is deformed inward in a manner yet to be described, so that both walls 7 and 9 in accordance with FIG. 2 and also in accordance with FIG. Fig. 5 come to lie against each other and guide and support one another and, above all, prevent unwanted and uncontrolled distortions and folds.
- Fig. 5 illustrates how the two walls 7 and 9 are gradually brought closer to each other until they actually touch each other in the bending area.
- the narrower bending roller 8 and the hold-down devices 11 and 12 to be described bring about the targeted and precise deformation of the individual webs 7 and 9, so that they are partially almost parallel to the outer walls 10 within the bend run.
- This not only allows the desired tight bend, but also leads to a correspondingly stiff and stable shape in the bending area despite the previous deformations.
- very thin-walled hollow profiles with tight bends with the smallest possible radius of curvature on the inside can be produced with the device 1 according to the invention.
- the pressure roller 8 is bevelled all around on its side surfaces 14 near its circumference, which acts as a working surface 13.
- This inclination is designated by 15 in FIG. 3 clearly shows that the greater width of the pressure roller 8 is equal to or less than the inside clearance of the side walls 10 of the profile 2 and that the narrower area 13 of the pressure roller 8 is approximately the width of an outside of the profile 2
- the bevels 15 on the side surfaces 14 of the bending or pressure roller 8 have a radial width which is equal to or - in the exemplary embodiment - greater than the immersion depth of the bending roller 8 when bending and pressing in the outer web 7 in the direction of the abutment 6.
- a piece of the bevel 15 protrudes from the profile 2 after the roller 8 has been pressed into it.
- the abutment 6, which has already been mentioned several times, is important for a rapid and problem-free course of the deformation during bending.
- This is a shaped piece which is somewhat modified in the various exemplary embodiments, the outer contour of which corresponds to the inner contour of the inner bend to be produced, as is illustrated, for example, in FIG. 5 .
- the abutment 6 protrudes at least temporarily during the bend in relation to the two inner sides or webs of the frame legs, which are at an angle to one another after the bend, in the direction towards the outer side of the bend and the profile, so that the inner side of the bend thus receives an indentation, as in Fig.1 and especially in Fig.5, but also in Fig. 3 is clear.
- the abutment 6 or the fitting serving as an abutment can be adapted to adapt to different profiles, web thicknesses, web shapes or the like. be interchangeable.
- the bending device 1 can thus be used above all for profiles of different dimensions. If necessary, it is also expedient to make the pressure roller 8 interchangeable.
- the abutment 6 can be moved or displaced deeper and deeper into the bend in the manner to be described during the bending process, possibly controlled.
- the inner wall 9 and outer wall 7 of the profile actually touch.
- this is achieved so early that, above all, the increasingly increasing bend can then take place when the walls 7 and 9 abut one another.
- the pivotable and / or displaceable abutment 6 is arranged immediately adjacent in the feed direction behind the clamping device 4 for detecting the profile area located before the bend. It is therefore separate from this tensioning device 4, so it can perform movements to optimize the bending process independently of these.
- the abutment 6 has a continuation 16 as a stop for the leg to be bent behind the bend at its pressure region which bears against the inside of the bend which arises during the bending.
- the abutment 6, with its continuation 16 serving as a stop can be pivoted together during the bending process with a bending stop 17 acting on the frame leg to be bent on the outside, the profile being clamped between the abutment continuation 16 and this bending stop 17, so that these parts practically form the device 5 for detecting the leg to be bent.
- Fig. 7 are this device 5 and the abutment 6 with its continuation independently.
- Figures 1.4 and 5 show a particularly expedient embodiment, in which the abutment 6 has a protrusion 6a projecting laterally and in particular eccentrically relative to its extension 16 for pressing into the inside of the bend which is formed, the dimension of which in the direction of its pivoting in the The sense increases that by pivoting the continuation 16 and the abutment 6 according to the arrow Pf 1 in FIG. 4, the projection 6a becomes increasingly deeper into the inside of the bend, as can be clearly seen when comparing FIGS. 4 and 5.
- dimension lines L are shown in the area of the projection a, starting from a central point M in each case to the periphery of the projection 6a, in order to increase the eccentricity of the projection 6a due to their length, which is increasing in the direction of the arrow Pf 1 caused gradually greater penetration of the abutment 6 to illustrate the profile 2.
- the arrow Pf 1 is also shown in Fig. 1. It can also be seen that the outside of the projection 6a is pivoted and the wall 9 pulls as it were. Modified solutions with regard to the gradual deeper entry of the abutment 6 into the inside of the bend are shown in FIGS.
- the abutment and a continuation 16 located on it are arranged at an acute angle to the incoming, not yet bent profile 2 and are slidably mounted in this orientation according to arrows Pf 2 and Pf 3.
- the area of the inside of the bend which arises can again be indented, in which case the shaped piece forming the abutment 6 has practically an arcuate or circular arc-shaped outer contour.
- the pivoting movement of the pivotable abutment 6 with its continuation 16 which acts with its surface on the inside of the bend in the sense of the profile feed during the pivoting, at least one displacement movement directed in the direction of orientation of the continuation 16 according to the double arrow Pf 2, in the exemplary embodiment, such a displacement movement shortly after the beginning of the bend and a further displacement movement of this type shortly before completion of the bend is superimposed.
- the abutment 6 and its continuation 16 has a projection 19 engaging in a control curve 18, the control curve 18 being oriented substantially in accordance with the pivoting of this projection 19 when the abutment 6 is pivoted and Deflections 18a for the superimposed displacement movements.
- hold-down device 11 or a support 12 and a hold-down device 11 are provided for the side walls 10 of the profile 2 in the bending area, the distance between which can be adjusted to the width of the profile 2 and the subsequent clear distance between two glass panes.
- evasive movements of the side walls 10 as is particularly illustrated by FIG. 3.
- an ejector or the like directed by the abutment 6 against the inside of the bend in the region of the bending tool 8 in a manner not shown in detail. be provided, which makes it easier to remove the deformed profile after bending. If necessary, even the abutment 6 could serve as an ejector, especially in the solution according to FIG. 7, by a further displacement in the direction of the arrow Pf 3.
- the device 1 can be used, for example, to bend hollow spacer profiles filled with desiccant to form spacer frames for insulating glass panes.
- This can of course be done in a number of ways.
- FIG. 6 shows a solution for such a case in which the hollow profile 2 is perforated on the inside of the bend that is created, so that the desiccant later also becomes effective against the space between the panes.
- this compressed air nozzle 20 which serves to displace drying agent 3 from the bending area, is arranged near the abutment 6 and the clamping device 4 arranged on the inside. In this case, it even passes through this clamping device 4 and opens directly in front of the bending area and in front of the abutment 6, so that the air can blow free the bending area.
- the air nozzle 10 is directed obliquely against the inside of the area of the profile 2 located before the bend and includes an acute angle with the leg remaining before the bend and the direction of advance of the profile 2 when it is inserted into the bending device 1 .
- a larger part of the desiccant 3 will be blown forward in the direction of extension of the profile 2, but a part will also be blown back due to the resulting excess pressure.
- Fig. 6 it can be clearly seen that the bending area itself is free of the desiccant, while this has accumulated somewhat on both sides of this desiccant-free area because it has been displaced by the compressed air.
- the bend can be carried out without the drying agent 3 hindering it, in particular with continued blowing in of air, so that the walls 7 and 9 can also touch each other according to FIG. 3 despite the drying agent 3.
- desiccant could even remain in the bending area or reach it again, since, according to FIG. 3, an intermediate space remains or can remain between the inwardly deformed web areas 7b and the side walls 10.
- Another possibility is to first bend an empty profile 2 and then fill in desiccant subsequently, in particular before the profile is finally closed, or even before the last bend is carried out, although it is not absolutely necessary that all the legs of the frame are then complete are filled with desiccant.
- bending roller 8 can be interchangeable to adapt to different and, above all, different widths 2.
