Further, the movable roll stand unit 2b is fixed to the upper surface of a slide base 4 having a substantially flat plate shape in the illustrated embodiment, the slide base 4 is movable in the lateral direction with respect to the molding machine base 3, and is generally movable. The roll stand unit 2b is configured to be movable laterally with respect to the molding machine base 3.

That is, lateral slide rails 31, 31 are attached to the rear portion of the molding machine base 3 (as viewed from the traveling direction of the molding material A) and are connected to a slide drive motor and a speed reducer (not shown). A rotatable drive screw shaft 32 is mounted in parallel between the slide rails 31, 31. The slide base 4 is provided with fitting portions 41, 41 having lateral grooves on the front side of the lower surface and on the rear side of the lower surface, and a bearing 42 is arranged in the lateral direction at approximately the center of the lower surface. Then, the fitting portions 41, 4 of the slide base 4 are

Therefore, the slide base 4 can be moved laterally by the rotation of the drive screw shaft 32. Since the movable roll stand unit 2b is integrally fixed to the upper surface of the slide base 4, the movable roll stand unit 2b is moved to the molding machine base 3 by the control of a slide drive motor and a speed reducer (not shown). It can be moved laterally.

Further, an inlet guide table 5 is provided in the front part of the molding machine base 3, and a length measuring roll 51 and a feed roll 52 are arranged in a vertically opposed manner in the middle of the inlet guide table 5. Has been done. Then, the number of revolutions of the length measuring roll 51 whose circumference is defined in advance is measured by the rotary encoder 53 arranged at the end of the length measuring roll 51, and the amount of progress of the fed molding material A is measured. The measured amount of progress is introduced into a control mechanism (not shown), a predetermined ratio corresponding to the amount of progress is set, and a slide drive motor and speed reducer (not shown) connected to the drive screw shaft 32 are controlled. Therefore, the movable roll stand unit 2b can be laterally moved and controlled according to the progressing state (amount) of the forming material A.

A molding method using the molding machine having the above structure will be described below. The molding machine of the illustrated embodiment has one side edge B
A forming material A, such as a metal plate material, whose left edge in the drawing is formed parallel to the traveling direction is applied. First, when the molding material A is exposed to the entrance guide table 5 and is advanced between the length measuring roll 51 and the feeding roll 52,
Both rolls 51, 52 abut and support the forming material A and feed it to the front part of the fixed roll stand unit 2a.

At the forward end of the forming material A, one side edge B is bent by the forming roller 11 in the front row of the fixed roll stand unit 2a. Then, with the progress of the forming material A, the forming rollers 11 and 11 in the second row and the last row of the fixed roll stand unit 2a sequentially perform deeper bending. In this way, the bent portion C formed by molding the one side edge B of the molding material A is formed.

In the next step, the molding material A is used for the slit cutter 1 in the front row of the movable roll stand unit 2b.
The other side edge D (the right side edge in the drawing) is cut by 6, but the movable roll stand unit 2b is gradually laterally outside (in the drawing) in accordance with the progress state of the forming material A as described above. Since the movement is controlled to the right side in the above), the slit cutter 16 also moves to the outside in the lateral direction accordingly, and the other side edge D is cut into a taper shape. The mill ends produced by the cutting may be wound up by a roll or the like not shown. Subsequently, the other side edge D that is cut into a taper shape is continuously bent by the forming rollers 11 arranged in three rows. Therefore, the exterior material F having the bent portion E formed by molding the tapered other side edge D is manufactured.

As described above, in the molding machine of the present invention, the fixed roll stand unit 2a forms one side edge B of the forming material A, and the movable roll stand unit 2b forms the other side edge D of the forming material A. Therefore, it is excellent in productivity.

Further, particularly in the illustrated embodiment, since the movable roll stand unit 2b is provided with the slit cutter 16, a rectangular forming material A can be applied, and two steps of cutting and forming are continuously performed. Therefore, the productivity is further improved. If the slit cutter 16 is not provided, it is necessary to use the forming material A which is formed in a tapered shape in advance.

Further, in the illustrated embodiment, the movable roll stand unit 2b is arranged laterally movable with respect to the molding machine base 3 via the slide base 4, so that the movable roll stand unit 2b can be moved relative to the slide base 4.

In this case, the facing portion 3 can be formed along the taper angle of the forming material A, and can be adapted to the forming of the forming material A having various taper angles. The movable roll stand unit 2b may be directly arranged on the molding machine base 3 without providing the slide base 4 itself. In this case, for example, the fitting portion 41 and the bearing 42 provided on the lower surface of the slide base 4 may be attached to the lower surface of the movable roll stand unit 2b.

Further, although not shown, each roll stand 1 ... May be housed individually in a casing, and the roll stand units 2a, 2b may be constituted by these aggregates. Further, in the illustrated embodiment, the forming roller 11 ... Which simply bends the one side edge B and the other side edge D of the forming material A in a substantially vertical shape is shown, but the present invention is not particularly limited thereto. That is, by selecting an appropriate shape as the forming roller 11, for example, an engageable shape such as fitting, overlapping, or engaging may be formed. In addition, the left and right side edges of the molding material A may have a curved shape instead of a straight shape.
