DETAILED DESCRIPTION OF THE INVENTION
The rest bar device shown in FIGS. 1 to 3 includes a rest bar 1, a saddle 2, a saddle movement drive means 3, a saddle clamp mechanism 4, and a guide clamp mechanism 5.
The rest bar 1 is provided with a support portion 1 a for supporting the saddle 2. In the example shown in the figure, the support portion 1a is formed in a quadrangular shape, and a slide member 6 that is long in the length direction (left and right direction in FIG. 3) is fixed to each side surface of the outer periphery.
The saddle 2 is attached to the support portion 1a of the rest bar 1 so as to be movable in the length direction (left-right direction in FIG. 3). In the example of FIG. 1, the saddle 2 is formed in a rectangular tube shape, and is disposed in a state where the support portion 1 a is inserted into the saddle. The saddle 2 can be moved by the driving of the saddle movement driving means 3, and the support portion 1 a can be smoothly slid by the presence of the slide member 6.
The saddle movement driving means 3 is constituted by a shift jack, and is arranged on one side of the saddle 2 (left side in FIG. 2). The main body of the shift jack that is the saddle movement drive means 3 is a shift cylinder 7 that is actuated by hydraulic pressure in the examples of FIGS. The shift cylinder 7 is attached to one side of the rest bar 1 by a bracket 8. The tip of the rod 7 a in the shift cylinder 7 is connected to the side surface of the side plate 2 a of the saddle 2. 9 is a hydraulic motor.
An upper portion of the saddle 2 is provided with a placement portion 2 b for placing and holding the lower portion 10 a of the guide device 10.
As shown in FIG. 1, the saddle clamp mechanism 4 includes a saddle clamp cylinder 11 attached to the lower surface of the saddle 2, and a hole-shaped clamping recess 1b cut inward from the lower surface of the support portion 1a of the rest bar. It has. A clamp portion 12 is attached to the rod 11 a of the saddle clamp cylinder 11. The rod 11 a passes through the bottom of the saddle 2. The clamp part 12 can move up and down in the concave part 1b for clamping of the support part 1a as the rod 11a moves forward and backward. The clamp part 12 can be engaged with the inner bottom part of the concave part 1b for clamping in the rest bar 1 (see FIG. 1).
The guide clamp mechanism 5 includes a guide clamp cylinder 13 and a guide plate 14. The guide clamp cylinder 13 is attached to the side plate 2a of the saddle 2 in an inclined state with the left side of FIG. The tip of the rod 13 a of the guide clamp cylinder 13 is connected to the guide plate 14. The guide plate 14 is attached to the front side of the saddle 2 (the right side surface in FIG. 1) via a support shaft 15. The guide plate 14 is rotatable around a support shaft 15 disposed on the rear end portion (lower end portion in FIG. 1). A hook 14 a is provided at the tip (upper end) of the guide plate 14. As shown in FIG. 1, the hook 14 a can fix the lower portion 10 a of the guide device 10 on the saddle 2.
[0007]
Next, the usage method will be described.
When the guide device 10 is shifted to the caliber, the lower portion 10a of the guide device 10 is pressed with a predetermined tightening force with the hooks 14a of the guide plate 14 as shown in FIG.
First, as shown in FIG. 4, the saddle clamp cylinder 11 is operated, the rod 11a is retracted, and the engagement between the clamp 12 and the clamp recess 1b is released. For this reason, since the saddle 2 is released from the support portion 1a of the rest bar 1, the saddle 2 is movable on the rest bar.
Next, the shift cylinder 7 for saddle control arranged on the side of the saddle 2 is driven, and the saddle in the released state is moved on the support portion 1a and stopped at the shift position.
Then, as shown in FIG. 1, the clamp part 12 is advanced through the rod 11a of the saddle clamp cylinder 11 and engaged with the inner bottom part of the concave part 1b for clamping. As a result, the saddle 2 is fixed to the rest bar 1.
In the fixed state of the saddle 2, the guide operation of the rolled material is started by the guide device 10 that has been fixed on the saddle from the beginning.
When the guide device 10 is replaced or removed from the saddle 2, the guide plate 14 is rotated clockwise about the support shaft 15 as shown in FIG. To do.
According to the illustrated example, since the guide clamp mechanism 5 is attached to the saddle 2, the guide device can be shifted while the guide device 10 is fixed to the saddle 2 with the guide plate 14. Opening and fixing work is unnecessary. For this reason, there is an advantage that the guide device can always be fixed with the same tightening force and the posture of the guide device is always constant. The saddle clamp mechanism 4 is disposed on the saddle 2, and the saddle is fixed by the hydraulic pressure in the shape of the clamp portion 12 that can be engaged in the clamp recess 1b. (Left and right) displacement and backlash are eliminated, and the posture of the saddle 2 is stabilized. Also, the guide clamp cylinder 13 is attached to the saddle 2 at an angle as shown in FIG. Furthermore, by arranging the shift jack 3 on the side of the saddle 2, the shape of the rest bar 1 can be simplified, and the scale removal of the joint surface (slide surface) between the saddle and the rest bar is facilitated.
[0008]
The saddle clamp cylinder 11 does not necessarily need to be attached to the saddle 2 as shown. The saddle movement drive means 3 is not necessarily limited to a shift jack using hydraulic pressure. The shape of the concave portion 1b for clamping is not limited to a hole shape, and may be a groove shape that is long in the direction perpendicular to the paper surface of FIG.
[0009]
【The invention's effect】
According to the present invention, since the saddle can move the rest bar and does not use the shift screw shaft as in the conventional example, it is easy to remove the scale of the joint portion between the saddle and the rest bar, and the maintenance management of the apparatus is simplified. Become. According to the present invention, since the saddle and the guide clamp mechanism are integrated, shift adjustment can be performed while the guide device is fixed at the time of shift, and the opening and fixing work of the guide device for each shift adjustment can be omitted. The attitude of the guide device can always be kept constant, and the rolling material can be guided and guided stably.
