[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a forming machine for forming a folded plate type architectural board in which tall chevron portions and bottom portions are alternately continuous using upper and lower forming rolls. The present invention relates to a roll adjusting device for a molding machine that can adjust the clearance between the upper and lower molding rolls of each of the upper and lower molding roll groups for a plurality of sets at once.

[Conventional technology and its problems]

BACKGROUND ART Conventionally, a roll forming machine has been used to form a folded plate type architectural board having a high height (for example, 15 ci or more) in which convex portions and bottom portions are alternately continuous from a rolled metal strip. The roll forming machine has a structure in which a plurality of roll groups each including an upper forming roll and a lower forming roll as a set of upper and lower forming rolls are provided in the longitudinal direction of a machine frame. When the metal strip is inserted from one end of the roll forming machine, the metal strip is carried into the roll forming machine by the rotation of the upper and lower forming rolls of the upper and lower forming rolls, and as it progresses, it gradually The metal strip is bent so that the chevron portions and bottom portions are alternately continuous in the width direction, and the completed construction board is delivered to the other end of the roll forming machine.

Then, the clearance between the upper forming hole and the lower forming roll of each upper and lower forming roll gradually becomes equal to the thickness of the metal strip from the entrance to the exit of the metal strip of the roll forming machine. Alternatively, it may be made slightly narrower than the thickness of the metal strip so as to press the metal strip.

Since the clearance between the upper and lower forming rolls of each of the upper and lower forming rolls was adjusted in steps of -m, it took a long time to complete the clearance adjustment of the upper and lower forming rolls of the entire roll forming machine. Not only is this process time-consuming and troublesome, but it also causes the inconvenience of increasing the manufacturing cost of architectural boards.

Therefore, it has been desired to be able to accurately and quickly adjust the clearance between all the upper and lower forming rolls of the upper and lower forming roll group.
