Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bending machine for bending a metal plate material used for a metal roof material, a metal outer wall material or the like at 90 ° or the like.

[0002]

2. Description of the Related Art A conventional folding machine of this type has only a fixed-type folding machine which is heavy and robust.

[0003]

However, this type of folding machine cannot be brought to the construction site, especially on the roof, and therefore the work of bending the base material during construction cannot be performed. In addition, when processing a long metal roofing material to 90 ° on site at the site where it joins the roof wall, even if it is treated with caulking material in order to make a notch in the goby part with scissors, after construction There was a drawback that caused a big complaint such as leakage of rainwater.

[0004]

SUMMARY OF THE INVENTION In order to eliminate such drawbacks, the present invention is a bending machine for bending a long base material made of a metal plate, and a fixing portion for fixing the base material and a bending portion for fixing the base material. It consists of a fixed fixed roll that matches the diameter and a moving roll that can move the outer peripheral surface of the fixed roll around the center of the fixed roll. The present invention provides a folding machine that sandwiches a base material and bends the base material by rotating a moving roll.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A folding machine according to the present invention will be described in detail below with reference to the drawings. 1 to 4 are views for explaining a folding machine according to the present invention, in which A is a folding machine, 1 is a base material, 2 is a fixing portion, and 8 is a folding portion.

More specifically, the base material 1 is made of a metal plate material, and its material is iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel sheet, enamel steel sheet, clad steel sheet, laminated steel sheet (PVC steel sheet, etc.). ), Sandwich steel plates (damping steel plates, etc.) and the like (including, of course, colored metal plates coated in various colors) are formed into various shapes by roll molding, press molding, extrusion molding or the like.

The base material 1 may be a metal roof material, a metal outer wall material or the like, as shown in FIG. 5 (a).
It is composed of a long dovetail, a roof tile, a roofing, a flat roof, a square corrugated plate, a round corrugated plate, etc. as shown in (f) to (f).
The bending is performed at the end 1a of the opening of the base material 1. In the figure, since the fixed portion 2 and the moving roll 10 are formed on the upper side, the back surface 1b of the base material 1 is formed on the upper side.

The fixing portion 2 is for fixing the base material 1, and is formed of a rotary shaft 3, a support plate 4, a fixing plate 5 and a fixing tool 6.

The fixing portion 2 is fixed to a fixing base 7, and the base material 1 is sandwiched between fixing plates 5 which are rotatably formed, and fixed by a fixing tool 6.

The material of the support plate 4 and the fixed plate 5 is a metal material, synthetic resin, rubber or the like.

Of course, the supporting plate 4 and the fixing plate 5 that match the material and molding shape of the substrate 1 are used.

The fixing member 6 is for fixing the base material 1 sandwiched between the supporting plate 4 and the fixing plate 5 so as not to flutter.
It is fixed by being rotated.

The fixed base 7 suspends and fixes the fixed portion 2 and the bent portion 8. As its material, H-section steel,
It is made of I-shaped steel, grooved steel, lightweight grooved steel, lip grooved steel, equilateral angle steel, unequal edge angle steel, wood, or synthetic resin material (plastic).

The bent portion 8 is shown in FIG.
As shown in FIG. 7 and house B, wall base C and outer wall material D
The fixed roll 9 and the movable roll 1 are used when bending at a portion where the roof wall between them is joined.
0.

The fixed roll 9 is mounted on a fixed base 7. The fixed roll 9 may be either non-rotatable or rotatable.

The movable roll 10 is the center point 9 of the fixed roll 9.
The outer peripheral surface 9b of the fixed roll 9 is formed so as to move about the center of a while rotating as shown by the dotted arrow and moving as shown by the two-dot chain line arrow. In addition, the moving roll 10
Rotates about the center point 10a. In this way, by moving the moving roll 10, the end portion 1a of the base material 1 is bent at 90 ° as shown by the dotted line.

The material of the fixed roll 9 and the movable roll 10 may be a metal roll, a rubber roll, a synthetic resin roll (made of plastic), or the like.

Of course, the fixed roll 9 and the movable roll 10 are used according to the material and the molding shape of the substrate 1.

Reference numeral 11 is a clearance adjusting portion, and 12 is a handle for rotation, which is formed so that the base material 1 of various shapes can be easily bent.

The clearance adjusting unit 11 adjusts the distance between the center point 9a of the fixed roll 9 and the moving roll 10a, and the distance is set by rotating the adjusting units 11a formed at both ends.

Although the substrate 1 is bent by rotating it by 90 ° in the figure, it may be necessary to bend the substrate 1 by 90 ° or more due to the spring back of the substrate 1 (the force to return to the original state). The rotation angle (bending angle) is not particularly limited. Of course, it is preferable to form at an angle of 90 ° or more in consideration of springback.

[0022]

Other Embodiments The above description is just one embodiment of the folding machine according to the present invention, and it can be formed as shown in FIGS. That is, FIG.
9A to 9H are cross-sectional views showing other examples of the fixed roll 9.

Further, in FIGS. 10 (a) and 10 (b),
(A) is a folding machine A in which the shape of the fixed base 7 is formed as shown in the figure, and the moving roll 10 is formed so as to stop at a moving angle of 90 ° or more, and (b) is the fixing part 2. Is a folding machine A formed so as to be close to the bending portion 8 and facilitate the bending process.

[0024]

As described above, according to the folding machine of the present invention, the formed metal roofing material, metal outer wall material and the like can be bent at the site (R-bending) to improve the workability. To do. Since the folding machine itself can be mass-produced, it can be manufactured at low cost. It is both portable and easy to carry. Bending can be done easily. There is no need to use scissors, and the waterproofness of the roof wall and other parts is perfect. There are features and effects such as.
