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! I topic]

Traditionally, roll forming machines have been used to form folded construction boards with high heights (for example, 15 cm inside and outside) in which convex portions and bottom portions are alternately continuous, from rolled metal strips. . The roll forming machine C 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 the 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 roll and the lower forming roll of each of the upper and lower forming rolls is adjusted so that it 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, or It is designed to be slightly narrower than the thickness of the metal strip so as to press the strip.

The clearance adjustment between the upper and lower forming rolls of each of the upper and lower forming rolls was done one set at a time, so it took a lot of time to complete the clearance adjustment of the upper and lower forming rolls for all roll forming machines. This process is not only troublesome, but also has the disadvantage 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.

[Effect of the invention] In the invention of claim 1, in a forming machine for a folded plate-like architectural board E having a high height, the initial stage forming roll group B1
．． On each upper forming roll Rup of the middle-stage forming roll group C1 and the final-stage forming roll group, a first vertical adjustment rod 6 having a threaded portion 6a with the same pitch p is attached to the upper end of the first vertical adjustment rod 6, which gradually moves toward the later stages. The first adjusting wheel 9 with a larger diameter φ is fixed, and the entire first adjusting wheel 9 is provided in the molding machine.
9. The endless flexible body 11 is wound around the endless flexible body 11, and at the same time, each of the initial stage forming roll group B, the middle stage forming roll group C2, the final stage forming roll group By using this as a roll adjustment device for a molding machine that can be raised and lowered to different predetermined heights, firstly, the entire adjustment can be made easily and quickly, and secondly, the height of the rolls of the entire molding machine can be adjusted. can be made identical and accurate, and thirdly, the structure is simple and can be provided at low cost.

To explain these effects in detail, first, in the past, the upper and lower forming rolls at each stage were adjusted up and down one by one, but in the present invention, the upper forming roll group B in the initial stage and the forming roll group B in the middle stage By driving the endless flexible body 11 of all the C1 final stage forming roll groups, the upper forming roll Rup can be adjusted up and down at - degrees, and as a result,
There is an advantage that the clearance between the upper forming roll Rup and the lower forming roll Rdn can be adjusted extremely easily and quickly.

In particular, in the present invention, the upper end of the first vertical adjustment rod 6 having the threaded portion 6a with the same pitch p has the 11th! Since the straightening wheel 9 is fixed, by moving the endless flexible body 11 at once,
The rotation angle on the side with a larger diameter φ becomes smaller, which allows the first vertical adjustment rod 6 on the front stage side to be raised and lowered more greatly, and the clearance can be changed for each group. In the case of a construction board E with a high thickness, for example, a construction board E such as a folded board, the initial stage forming roll group B
Then, the plate thickness of the formed plate is about 1 kaku, the thickness of the formed plate + about 0.5 wi in the middle stage forming roll group C, and the same as the plate thickness in the final stage forming roll group, For the first time, it is possible to form a well-ordered architectural board E without causing stress distortion, and it has the great effect of allowing different clearance adjustments for each group to be made at once.

Even if it is adjustable as described above, in particular, even if there are a large number of first vertical adjustment rods 6, they can be made the same, and the height adjustment is made only by the clearance that is inversely proportional to the diameter φ of the first adjustment wheel 9. It has the advantage of being easy to obtain in large quantities.

Next, in the invention of claim 2, the first threaded portion 6a having the same pitch p as that of the invention of claim 1,
A first adjustment wheel 9 whose diameter φ gradually increases as it moves toward the rear group is fixed to the upper end of the vertical adjustment rod 6, and a threaded portion 7a whose diameter φ gradually becomes smaller as it moves toward the rear group. By replacing the second adjustment wheel 10 with the same diameter δ fixed to the upper end of the second vertical adjustment rod 7 having Although U has different surfaces, the diameter δ of the second adjusting wheel 10 is constant and the same, so it can be installed at low cost, and it protrudes from the upper side of the molding machine, so it does not pop out. Can be installed in an orderly manner.

The other configurations are the same as the invention of claim 1, and the same effects can be achieved.
