DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guiding device for transferring from one die to the next in the rolling production of angle steel, invert and channel steel. If
The present invention relates to a guide device which eliminates or remarkably facilitates adjustment and replacement work due to wear of upper and lower guards in contact with a rolling roll, and simplifies alignment work after use of upper and lower guards.

[0002]

2. Description of the Related Art Conventionally, a guide device shown in FIG. 1 is provided at a rolling hole exit in order to take out a rolled material (shaped steel) straight. This guiding device includes upper and lower guards 1 and 1 'for vertically sandwiching the section steel and guides 2 (2') for guiding the section steel in the left-right direction. Is in full contact with the rolling rolls 3 and 3 '
(2 ') stands on the slipper-4.

[0003]

In the above-mentioned conventional method, the section steel coming out of the rolling rolls 3, 3 'is bent and the guards 1, 1' are formed.
In order to prevent accidents such as projecting from the gap between the rolling rolls 3, 3 'and the guards 1, 1'
The guards 1 and 1 'are always kept in contact with the rolling rolls 3 and 3'. However, since the tips of the guards 1 and 1 'are severely worn, the guards are frequently replaced. In addition to this, abnormal wear may cause guard flaws on the upper surface of the section steel, or the clearance between the guard and the roll may cause a protrusion accident, etc. There was a problem.

In addition, there is the following problem, and the work is extremely difficult, so that the work efficiency is not improved. (1) Since the upper guard 1 is a cassette type and is suspended and fastened by the suspension bolt 5, the tip of the upper guard 1 is directed upward, it is difficult to fit the roll hole, and the ball is used. There are many adjustment operations, so not only does it take time to tighten the bolts of the upper guard 1 and the roll, but also the tip of the guard may not fit depending on the roll diameter (large or small). The slippers-4 were pulled together.

(2) Since the guard width is wide, it is difficult to measure from the inside with respect to the guide mounting position (roll reference line). (3) The gap between the guard and the roll was checked with an earpick, but this required a skill.

(4) It is necessary to adjust the guard every time it is used. Since the entire surface is adjusted with a grinder, it takes much time to correct the upper and lower guards. In addition, since the grinder correction work is performed by leaning forward on the middle waist, the work is awkward work such as causing back pain.

The present invention solves the above-mentioned problems, avoids abnormal wear of the guard, reduces the frequency of replacement of the guard, facilitates the matching operation for each use, and significantly improves the work efficiency. An object of the present invention is to provide an induction device for a shaped steel.

In the embodiment of FIG. 6, the lower arm 6 '
Are not in contact with the lower roll 3 ', and there are no side guide members 9' below the channel steel. This is because the channel steel may come out of the rolling rolls 3, 3 'by being bent upward, but not come out by being bent downward.

According to the present invention, the vertical guide has been brought into full contact with the roll, and the vertical guide and the horizontal guide have been provided by the vertical guide having the same shape as the shaped steel. A separate means is provided, and the vertical guide means
The rolling material does not wind around the rolling rolls, but can be guided by merely contacting the rolling rolls. The rolling material is guided by a completely different structure.

The upper and lower guide means 6, 6 'are formed rotatably, and the ends thereof are brought into contact with the upper roll 3 and the lower roll 3' by their own weights. Since a strong force is not applied to the means 6, 6 ', abnormal wear can be eliminated and wear at the tip can be reduced. As a result, the occurrence of guard flaws due to abnormal wear can be significantly reduced, the quality can be improved, and the occurrence of an overhang accident can be almost completely eliminated.

Further, even if the upper and lower guide means 6, 6 'are worn to some extent, the upper and lower guide means 6, 6' come into contact with the rolling rolls 3, 3 'by their own weight, so that they can be adjusted during rolling. ,
Since there is no need for replacement, the adjustment replacement work during rolling can be eliminated.

Since the upper and lower guide means 6 and 6 'of the present invention need only be brought into contact with the rolling rolls 3 and 3', there is no need for the conventional guards to be fitted to the roll holes. The matching operation is extremely simplified. That is, the work of aligning the roll with the tip of the upper guard as in the prior art is not required, and the work requiring skill to check the gap between the roll and the guard with an earpick is also unnecessary. .
