(3) In the device of the prior application, a spline joint is used in order to simultaneously drive the timing belts of the drive side frame and the work side frame with one input shaft (spindle), but each frame is opened and closed in a fan shape. Therefore, the attachment and detachment work was time consuming, but the present invention allows this attachment and detachment operation to be performed automatically and quickly.

(4) Since the device of the prior application uses a screw shaft-type reduction adjustment mechanism, the screw shaft receives a direct load, causing distortion in the threaded portion, and the scattered water and scale get caught in the threaded portion, making it rough. The handle was difficult to operate and had poor workability, but in the present invention, an eccentric cartridge type lowering adjustment mechanism is adopted to make the handle easier to operate.

(5) Since the device of the prior application uses a screw shaft type downward adjustment mechanism, a link mechanism consisting of a total of four points, the fixed fulcrum on the frame side (two points) and the screw engagement part (two points), is formed, and the screw Since the shaft has a swingable support structure, it was difficult to adjust the roller position with high precision due to the backlash of each sliding part, but with the present invention,

2b and scale plates 47a to 50a, 61a, 62a
Accordingly, each knife 35, 36, each roller 3
Since the reduction amounts and relative positions of 7, 38, 55, and 56 can be visually observed, confirmation becomes easy.

Furthermore, since there is no link mechanism such as the screw shaft type downward adjustment mechanism of the device of the prior application, the work side frame 21 can be made more compact. Therefore, a large work space can be secured, and the misrolled material can be moved between the knives 35, 36 and the separator rollers 37, 3 without sliding the drive side frame 20 in the opening direction.
Since the melt can be cut between 8, 55, and 56, misroll processing can be easily performed.

(7) Note that in the device of the prior application, a pinch roller was provided in addition to the rotating knife and the separator roller, but in this embodiment, no pinch roller is provided. That is, in the actual operation of the device of the prior application, it was found that the separator roller also served as a pinch roller, and there was no particular advantage in providing the pinch roller.

In addition, rotating knives have significance in terms of centering the rolled material and controlling the thickness of thin-walled parts.In particular, the split head difference between the left and right sides of the separator roller is small, and the thin-walled parts of the rolled material are thick and there is a danger of not being able to cut them completely. It is absolutely necessary at some point.

However, in actual operation, the separator roller provides the necessary split head on the assumption that the thin section becomes thicker due to wear of the rolling caliber upstream of the rotating knife.

Therefore, it is also possible to perform splitting by simply providing guides before and after the separator roller without providing a rotating knife.

In this case, the driving side frame can be made compact like the working side frame.
