The present invention also relates to a skin pass roller vertical movement fine adjustment device having a roller thrust (axis) direction adjustment device for preventing roller misalignment.

上の問題とローラを組み立てるときの組立精度の
問題があるからである。(Conventional technology) Conventional precision rolling is to lightly reduce the shape of a long steel product, so the precision of the roller caliber shape and the accuracy of the alignment of a pair of rollers are the most important. It's important. Normally, a pair of roller caliber (hole type) cores 38a and 38b have quite a difference in the center of the roller hole as shown in Fig. 5, so if this condition is left as is, it will naturally result in poor dimensional accuracy or defects in the product due to misalignment of the product. This was the cause of such problems. The factors that cause this roller hole center misalignment include processing problems that inevitably result in an error of about 5/100 in the machining accuracy of the roller caliber (hole shape), and assembly accuracy problems when assembling the roller. It is from.

いた。 As a means of solving the above error, there is also a method in which push bolts are installed above and below the roller shaft, and the roller support shaft is pushed and lifted or pulled down depending on the screwing amount of the push bolts to move the roller up and down. However, this method has problems such as the inability to make very minute adjustments in the vertical direction of the rollers, and the workability of turning the lower push bolts is poor, as well as the fact that adjustments must be made while balancing the upward and downward pressure. Since then, I had to go through a lot of trial and error. In other words, it required skill.

ある。(Problems to be solved by the invention) The present invention was made to solve the above problems, and as a more advanced adjustment method, it uses a high reduction worm mechanism and a screw mechanism to adjust the roller speed. The movement in the thrust direction is made extremely small and can be performed in one operation, thereby preventing roller flange jamming of the product and greatly improving the cross-sectional dimension of the product.
