Abstract

PROBLEM TO BE SOLVED: To rapidly form a riser part on each side in the width direction of a tapered metallic sheet by providing a rotational force transmitting shaft to drive upper and lower forming rolls slidably in an axial direction relative to each roll forming body, and providing a drive sprocket on each sliding shaft slidably only in the axial direction. SOLUTION: An angle adjusting handle 21 is turned to move an angle adjusting screw shaft in the axial direction, and a free side of a roll forming body A is pressed by a shaft end to adjust the angle of a tapered metallic sheet. By turning an angle adjusting handle 21 to the opposite side, the pressing of the roll forming body A by the shaft end of the angle adjusting screw shaft is released, and the roll forming body A is returned to its original condition by the restoring force of a spring 23 to agree the forming direction of the upper and lower forming rolls R, R of the roll forming bodies A, A, and the angle of each inclined side of the tapered metallic sheet with each other. The tapered metallic sheet is inserted between the roll forming bodies A, A, and a riser part is formed on each inclined side to manufacture a plate for construction use.

2. Description of the Related Art Conventionally, a metal thin plate is appropriately processed to form a metal building plate, and various types of enclosures are constructed from the building plate. Recently, the outer enclosures have become more dome-type, and the construction plates forming the dome-type outer enclosures have a tapered shape. In order to form such a tapered building plate, it is necessary to form the original metal plate into a tapered shape and then form rising portions on both sides in the width direction.

In order to form such a tapered original metal plate from a thin metal plate, it is necessary that the forming direction of the forming roll portion of the forming metal plate coincides with the hypotenuse direction. As described above, the tapered original plate must be bilaterally symmetric, and its work must be accurate and precise. Therefore, skilled workers are required to form the tapered original plate.

It is composed of a rotational force transmission shaft and a drive sprocket that drives the upper and lower forming rolls via the drive unit. The rotational force transmission shaft is provided so as to be slidable in the axial direction with respect to both roll forming bodies. On both sliding shafts A taper-shaped thin metal plate forming machine that is slidable only in the direction allows the taper-shaped thin metal plate to be easily and quickly formed into a tapered building plate.
