Definitions
- 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.
- 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.
- 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.
- FIG. 7 shows a view of the device from FIG. 6, in which the clamping jaws and the bending punch are in a starting position for a new bending process
- FIG. 8 shows a view of the device from FIG. 6, in which both the clamping jaws of the clamping device and the bending punch of the bending device are in the bending position
- 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 width of this web 37 is adjusted to the end faces 38 and 39 of the upper bending punch 8 and the lower bending punch 15 in order to be able to bend a uniform trapezoid 11.
- the lower jaw 3 is provided with a shoulder 40 (see FIGS. 2 to 5), which acts as an abutment for the lower end 10 of the upper Bending punch 8 serves, as can be seen in particular from FIGS. 2 to 5 demonstrating the individual method steps.
- the whole is arranged in a schematically indicated machine frame 61.
