Definitions
- the invention relates to a device for bending hollow profile strips, in particular for bending hollow profile strips to form spacers for insulating glass panes, with two jaws which can be placed on the side surfaces of the hollow profile strip to be bent, an abutment around which the hollow profile strip is bent, and a bending lever which is opposite the Abutment for performing the bending work is pivotable.
- a problem with the known bending devices is that the sharp-edged bends required for use in insulating glass panes cannot always be achieved without problems, since there is a risk in part of that the walls of the hollow profile strip tear during the bending process and the side surfaces of the hollow profile strips in the corner area, ie where they have been bent, do not always run flat, but have corrugations which the subsequent processing of the spacer frame, in particular the coating of the side surfaces of the spacer frame with sealing - or hamper and hinder adhesive.
- EP-A-318 748 describes a device for bending hollow profile strips to form spacer frames, the abutment of which is movably mounted and is intended to perform a pivoting and / or displacement movement during the bending process.
- the pivoting movement of the abutment follows the movement of the bending lever which acts on the hollow profile to be bent from the outside. This is intended to ensure that the inner wall of the hollow profile moves inward during the bending movement and finally rests on the outer wall which is likewise deformed inward by the pressure roller.
- a control cam can be provided which additionally moves the abutment in the direction of its longitudinal extension during its pivoting movement.
- the device for bending hollow profile strips described in DE-OS 29 23 769 has a tool that can be advanced during the bending process, by means of which the web of a longitudinal section of a spacer strip is to be deformed at the highest point of the bend during the bending process.
- the "counter bearing tool” is to be pushed into the highest point of the bend with the aid of a wedge during the bending process.
- the bending tool is also intended to form the lateral guide for the side flanks of the U-shaped spacer strip, the distance of the guide surface for these side flanks on the counter bearing tool not being changeable, since this is made in one piece.
- the invention has for its object to provide an improved bending device (bending head) with which hollow profile strips can be bent to each other at largely arbitrary, selectable angles of the legs adjacent to the corner.
- the device according to the invention for bending hollow profile strips 1 consists of a clamp 2 with a stationary clamping jaw 3 and a clamping jaw 4 which is movable with respect to this (the clamping jaw 4 is not shown in FIG. 1).
- the movable clamping jaw 4 can be displaced in the direction of the double arrow 7 (FIG. 2) via guide pins 5 and 6, which are each arranged in pairs, so that the mouth width of the clamp 2 can be adapted to the width of the hollow profile strip 1 to be bent.
- a lever 8 pivotally supported on the stationary jaw 3 is provided.
- the lever 8 is coupled to the movable jaw 4 via a pull rod 9 which is pivotally supported on the jaw 4 via a bearing 10.
- the pivot lever 8 is driven by a linear motor, not shown, e.g. a double-acting pressure cylinder actuated.
- the carrier 21 for the abutment 20 is mounted on a lever 25, which is about a bearing 26 fixed to the machine frame, ie a bearing which is not movable relative to the stationary jaw 3 of the clamp 2, with the aid of a linear motor 27, for example a double-acting pressure medium cylinder. in the direction of the double arrow 28 from the one in FIG. 1
- the active position shown with solid lines can be pivoted into the standby position shown in dash-dot lines in FIG. 1.
- the support 21 for the abutment 20, as shown in FIG. 2 is perpendicular to the plane of symmetry of the clamp 2, namely adjustable in the direction of the double arrow 29 shown in FIG. 2.
- the carrier 21 is guided displaceably via guides 30 in a holder 31 connected to the lever 25.
- a linear motor in the exemplary embodiment shown a double-acting pressure medium cylinder 32, is provided, the piston rod 33 of which is coupled to the carrier 21 via a pull rod 34.
- the abutment 20 can be pivoted not only in a plane parallel to the plane of symmetry of the clamping jaw 2 (double arrow 28), but also in a direction perpendicular to the plane of symmetry of the clamp 2 (double arrow 29), so that the abutment 20 is completely removed can be moved out of the bending area.
- the abutment 20 carries at its front tip, which is formed by two inclined surfaces 36, which form an acute angle to the longitudinal extension of the flexible abutment 20, a bead-like extension 35, which like Fig. 4 shows the upper surface of the hollow profile 1, which is clamped in the clamp 2 between the jaws 3 and 4, before the beginning of the bending process, namely when the bending abutment 20 swings slightly in its active position.
- the front end of the abutment 20 and the bead-shaped extension 35 adjoining the inclined surfaces 36 there are somewhat narrower than that clear distance between the mutually facing surfaces of the jaws 3 and 4 of the clamp 2.
- the side walls 40 of the hollow profile strip 1 to be bent are also supported from the inside during the bending process, as is indicated in the section of FIG. 5.
- an angled stop surface 41 is provided on the abutment 20 in the region of its front end on one side which cooperates with a step 42 on the fixed jaw 3.
- the bending lever 50 is pivoted back, the clamping jaw is opened and the hollow profile strip 1 is pushed forward until the position of the hollow profile strip 1, in which a further corner is to be produced, is correctly aligned with respect to the bending tool. Then, as described above, the next corner is bent. This continues until a spacer frame with the desired number of corners 51 - usually four - is finished.
- the bending device according to the invention is preferably suitable for bending machines with an upwardly facing contact surface for the angled parts of the hollow profile strip 1 (for example DE-GM 87 05 796). Another advantage is that the abutment 20 in its standby position the removal of the spacer frame not hindered, since it is arranged behind the abovementioned contact surface.
- the invention also extends to an embodiment in which a freely rotatable roller 70 is provided at the free end of the abutment 80 instead of the bead-shaped extension 35.
- the roller 70 has a width corresponding to the extension 35. This embodiment is shown in FIG. 7.
- Both embodiments of the bending device according to the invention can also be used to produce arches 71 in hollow profile strips.
- the hollow profile strip 1 is pushed forward by a feed device when the abutment 20 or 80 is pivoted in, the bending lever 50 being pivoted somewhat upward as shown in FIG. 7.
- the radius of curvature of the arc 71 thus produced in the hollow profile strip depends on how far the bending lever 50 is pivoted upwards, i.e. of how high the e.g. Bending attachment 52 made of plastic with a low coefficient of friction stands above the feed path (determined by the guide pins 6).
