Definitions
- the invention relates to a method and a device for bending a material web, in particular metal strip in a trapezoidal shape, which is intended, for example, as a web material for welded web profiles.
- the material web preferably consists of a steel strip, but other materials such as aluminum, metal alloys and plastics, which can preferably be welded or glued, are also conceivable.
- each pair of clamping jaws being assigned a bending jaw which can be pivoted about the horizontal axis and a supporting jaw is arranged between the two pivoting bending jaws, opposite them, which supports the strip material to be bent between the bending jaws to get the desired trapezoidal shape.
- Bending device can only be formed relatively flat trapezoidal webs, because you can pivot the pivoted bending jaws only by a limited angle against the strip material to be deformed can. If this limit angle is exceeded, the pivotably mounted bending jaws can no longer be pivoted back into the starting position after the bending process, since the bending jaws which are displaced relative to one another during the bending process would interfere with one another when pivoting back.
- the length of the legs or flanks of the trapezoidal webs and the opening width of the trapezoidal profile are dependent on one another in the known arrangement.
- This known bending device is also limited by a certain size of the tools used for the bending process, that is, such a device cannot be retrofitted to other tool sizes.
- the invention has for its object to provide a method and an apparatus for bending a material web, in particular a steel strip, for example in a trapezoidal shape, with which or with which profiles with steeper legs or flanks of the trapezoid or the like and trapezoids or the like with different Can bend opening widths mechanically and without manual labor.
- the present invention on the one hand proposes a method in which a material web is bent by means of a
- the bending device undergoes a bending movement into the bending position.
- bending movement With a suitable choice of the bending movement, bending radii of the bent sheets can be maintained, which exclude an unfavorable change in the structure of the metal in the bending area.
- the invention proposes a device for bending a material web with a clamping device and a bending device.
- the bending device comprises at least one bending punch. This can be arranged above the material web and bend the material web into a desired shape, for example by swiveling it down into the bending position.
- the bending movement is synonymous with a working stroke of the bending punch.
- the bending position describes a reversing position, which is followed by the return movement.
- the return movement is synonymous with the return stroke of the punch.
- the material web to be deformed can be fixed in the device, for example, by at least one pair of clamping jaws, so that the material web is held in a defined position during the corresponding bending process.
- the pair of jaws be arranged such that there is at least one clamping jaw above the material web and at least one second clamping jaw below the material web.
- the material web can also be fixed on the side to be fed by a second pair of clamping jaws, which can be arranged in a similar manner to the first pair of clamping jaws.
- the pair of clamping jaws which acts on the side to be fed with the material web, can be displaced relative to the first pair of clamping jaws, so as to easily compensate for a shortening caused by the bending.
- a bending punch arranged between the pairs of clamping jaws can perform two bending processes in one working stroke.
- a first pair of clamping jaws which fixes the material web.
- the bending device differs in that not only is a bending punch arranged above the material web, but also a second bending punch is arranged below the material web.
- the upper bending punch first moves into a bending position, so that it fixes the material web with its tool against a shoulder of the clamping device or a further lower clamping jaw.
- the lower punch also moves into a bending position, so that the tool of the lower punch the material web clamps against a shoulder of the upper bending punch and the upper bending punch is thus used as part of the clamping device in this second bending process.
- a second pair of clamping jaws can be dispensed with, which can have an advantageous effect on the costs for the construction and maintenance of the device.
- the deviation according to the invention between the bending movement and the return movement means that these two movement sequences can be suitably and in particular optimized independently of one another.
- the bending punch In contrast to the bending movement, which for example runs through an almost circular path, the bending punch preferably runs through a linear movement section perpendicular to the material path during the return movement, which can be done in a much more space-saving manner.
- each bending punch is articulated, preferably by a Double joint, connected to the jaw that lies on the same side of the material band and corresponds to the bending punch.
- At least one bending punch can be designed to be interchangeable, the bending punch and also the clamping jaws being able to be provided with clamping or bending-specific tools. These tools are preferably also interchangeable, so that the bending device can also be meaningfully redesigned.
- the clamping device and the bending device have at least one bending edge, which are guided to one another in such a way that at least one free material section is present during a bending movement section.

- the lower position can be referred to as the bending position and the upper position as the return position.
- the upper bending punch 8, like the slide 4, is preferably adjustable perpendicular to the direction of travel of the material web 1, as indicated by a double arrow 9.
- the lower end 10 of the upper bending punch 8 provided for the bending process is wedge-shaped in order to be able to bend the material web 1 into the trapezoidal shape shown in the drawing. Any angle up to 90 ° between the legs 12 or flanks and the straight sections 13 of the trapezoid 11 can be selected, only the shape of the bending punch used having to be adjusted to the desired cross-sectional shape of the trapezoid or the trapezoidal profile.
- Above the lower end 10 of the upper bending punch 8 provided for the bending process there is a block-shaped stop on the side thereof
- the upper bending punch 8 is provided with two bearing plates 16 and 17 arranged at a distance from one another, on each of which a lever 18 or 19 can be pivoted about a pin 20 or 21 and is thus articulated at one end.
- the respective other end of the lever 18 or 19 is also articulated around a pin 22 or 23, which in turn is fastened to a bearing plate 24 or 25 of the slide 4. Therefore, the slide 4, which is adjustable perpendicular to the passage plane of the material web 1, and the upper bending die 8, which is preferably adjustable perpendicular to the passage plane of the material web 1, can perform relative movements to one another in the manner of a pendulum rocker, as can be seen in FIGS. 1 to 5. Within certain limits, both the slide 4 and the upper bending punch 8 can be set against the material web 1 independently of one another and can also be withdrawn therefrom.
- the lower punch 15 is mounted in the same way as the upper punch 8, namely via levers 26 and 27 which are arranged parallel to one another and which are arranged between the lower punch 15
- Bearing plates 28 and 29 and bearing plates 30 and 31 attached to the lower slide are pivotably mounted by means of pins 32 and 34 or 33 and 35.
- levers 18, 19, 26 and 27 do not necessarily have to be selected to be of the same length. Rather, these lever lengths can be varied depending on the desired trapezoidal shape or the desired sequence of movements.
- the upper end 36 of the lower punch 15 is in the same manner as the lower end 10 of the upper punch 8 wedge-shaped and cooperates in the opposite position with the opposite block-shaped stop 14 of the upper punch 8 in the manner of a clamp connection.
- a movement of the bending punches 8, 15 in the direction of deformation of the material web 1 (in the drawing from right to left) is possible in accordance with the shortening of the length of the material web 1 due to a bending step.
- the lower jaw 3 has an upright rectangular web 37, which actually serves as the jaw and forms a bending edge.

- the jaws 42 and 43 are each formed as a vertically movable carriage, which with a
- the second upper clamping jaw 44 can be moved in the forward direction of the material web 1 in accordance with a double arrow 50 and is therefore not adjustable against the material web 1 and also cannot be removed from it on a carriage 53.
- the clamping jaw 45 cooperating with this second clamping jaw 44 can be turned on and off perpendicularly with respect to the material web 1, as is indicated by a further double arrow 51. With the aid of a drive cylinder 52, this is supported on the carriage 53, which can be displaced in the horizontal direction by means of a further drive cylinder 54, as indicated by a double arrow 55.
- the upper bending die 41 is articulated via a double joint 56, 57 described in connection with FIG. 1 in the manner of a parallel rocker with the clamping jaw 42 designed as a slide in such a way that movements of the upper bending die are achieved in accordance with the double arrows 58 and 59 shown.
