Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rest bar device in a rolling guide device.

2. Description of the Related Art Conventionally, as a shift mechanism provided in a rest bar device of a rolling guide device, for example, as shown in Japanese Patent Application Laid-Open No. 6-015810, a guide device is provided on a shift screw shaft provided in the rest bar. In many cases, the guide device is shifted to the caliber while rotating the shift screw shaft in a state in which is mounted. Also, as a guide clamp mechanism provided in the rest bar device,
For example, as shown in JP-A-6-277737, there is an example in which a guide device on a rest bar is easily fixed using a plate-shaped guide clamp operated by a hydraulic cylinder.

According to the prior art, the scale tends to adhere to the shift portion of the shift screw shaft, and it takes much time and effort to clean the shift screw portion and the sliding portion on the guide device side. Improvements in the structure for facilitating maintenance of the device have been expected. Also, every time the guide device is shifted to the caliber, it is necessary to open and fix the guide clamp, and the tightening force of the guide clamp is not constant, and the fixing position of the guide device may be set in an oblique state. In some cases, this may adversely affect the accurate guidance of the rolled material. SUMMARY OF THE INVENTION It is an object of the present invention to improve the maintenance of the apparatus and to keep the attitude of the guide apparatus constant.

SUMMARY OF THE INVENTION The present invention is directed to a saddle for holding a rolling guide device, wherein the rest bar is movably disposed in the longitudinal direction of the rest bar by saddle moving driving means such as a hydraulic cylinder. And a saddle clamp mechanism for fixing the saddle to the rest bar, and a guide clamp mechanism attached to the saddle for fixing the rolling guide device to the saddle. The saddle clamp mechanism has a fluid pressure,
Those utilizing a cam mechanism or gears are included. For example, a device using fluid pressure includes a saddle clamp cylinder attached to a saddle, a clamp portion connected to a rod of the saddle clamp cylinder, and a clamp recess provided on a rest bar. The recess for use and the clamp can be engaged with each other. The configuration of the saddle movement driving means is appropriate, but one of the means is a shift jack attached to a rest bar. The guide clamp mechanism includes one using a fluid pressure, a cam mechanism, a gear, or the like. For example, in the case of using fluid pressure, a guide clamp cylinder and a guide plate which has a hook in conjunction with the guide clamp cylinder are provided, and the guide plate is rotatable about the support shaft on the saddle. And the rolling guide device held on the saddle by the hook can be fixed.

The rolling guide device is shift-adjusted while always being fixed to the saddle by the guide clamp mechanism, and the fixing is not released each time the adjustment is performed. That is, when adjusting the shift position, the saddle slides the rest bar in its length direction by the saddle moving drive means, and at the same time, the guide device fixed to the saddle by the guide clamp mechanism is also moved by the movement of the saddle, and the shift position Is adjusted. After the adjustment, the saddle is fixed to the rest bar by the saddle clamp mechanism, and after being fixed, the guide device guides and guides the rolled material. Only when it is necessary to remove the guide device from the saddle, such as when replacing the guide device for rolling, the fixing by the guide clamp mechanism is released.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The rest bar device shown in FIGS. 1 to 3 includes a rest bar 1, a saddle 2, a saddle moving drive means 3, a saddle clamp mechanism 4, and a guide clamp mechanism 5. The rest bar 1 is provided with a support portion 1a for supporting the saddle 2. The support portion 1a has a rectangular cross section in the illustrated example, and a slide member 6 that is long in the length direction (the left-right direction in FIG. 3) is fixed to each outer peripheral side surface. The saddle 2 is attached to the support portion 1a of the rest bar 1 so as to be movable in the length direction (the left-right direction in FIG. 3).
The saddle 2 is formed in the shape of a square tube in the example of FIG. 1, and is arranged with the support portion 1a inserted in the saddle. The saddle 2 can be moved by the drive of the saddle moving drive means 3, and can slide the support portion 1a smoothly due to 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 (the left side in FIG. 2). The main body of the shift jack serving as the saddle movement driving means 3 is a shift cylinder 7 which is operated 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. On the upper part of the saddle 2, a mounting part 2b for mounting and holding the lower part 10a of the guide device 10 is provided. The saddle clamp mechanism 4 is shown in FIG.
, A saddle clamp cylinder 11 attached to the lower surface of the saddle 2 and a hole-shaped clamping recess 1 cut inward from the lower surface of the support portion 1a of the rest bar.
b. A clamp portion 12 is attached to a rod 11a of the saddle clamp cylinder 11. Rod 1
1a penetrates the bottom of the saddle 2. Clamp part 12
Is the supporting portion 1 with the forward and backward movement of the rod 11a.
a can be moved up and down in the clamp recess 1b. The clamp portion 12 is provided with a clamp recess 1 b in the rest bar 1.
(See FIG. 1). The guide clamp mechanism 5 includes a guide clamp cylinder 13 and a guide plate 14. Guide clamp cylinder 13
Is attached to the side plate 2a of the saddle 2 in an inclined state with the left side in 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 (the right side in FIG. 1) of the saddle 2 via a support shaft 15. The guide plate 14 is rotatable about a support shaft 15 arranged on the rear end (the lower end in FIG. 1). A hook 14 a is provided at the tip (upper end) of the guide plate 14. The hook 14a can fix the lower part 10a of the guide device 10 on the saddle 2 as shown in FIG. Next, the method of use will be described. When shifting the guide device 10 to the caliber, the lower portion 10a of the guide device 10 is pressed with a predetermined tightening force by 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 portion 12 and the concave portion 1b for clamp is released. Therefore, the saddle 2 is released from being fixed on the support portion 1a of the rest bar 1, and thus can be moved on the rest bar. Next, the shift cylinder 7 for saddle control arranged on the side of the saddle 2 is driven to move the saddle in the released state on the support portion 1a, and is stopped at the shift position. Thereafter, as shown in FIG. 1, the clamp portion 12 is advanced through the rod 11a of the saddle clamp cylinder 11, and is engaged with the inner bottom portion of the concave portion 1b for clamp. As a result, the saddle 2 is fixed to the rest bar 1. Saddle 2
In the fixed state, the guiding operation of the rolled material is started by the guide device 10 which 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. I do. According to the illustrated example, since the guide clamp mechanism 5 is attached to the saddle 2, the guide plate 10
Since the guide device can be shifted while the guide device is fixed to the saddle 2, the operation of opening and fixing the guide device for each shift becomes unnecessary. Therefore, 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 hydraulic pressure in the shape of the clamp portion 12 engageable in the concave portion 1b for clamping. There is no shift or backlash in the left and right directions, and the posture of the saddle 2 is stabilized. The guide clamp cylinder 13 is provided with a saddle 2 as shown in FIG.
The guide device 10 is mounted obliquely so that its position does not hinder the attachment / detachment work of the guide device 10, so that the attachment / detachment work becomes easy. Further, by arranging the shift jack 3 on the side of the saddle 2, the shape of the rest bar 1 can be simplified, and scale removal of the joint surface (slide surface) between the saddle and the rest bar can be facilitated. 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 clamping recess 1b is not limited to a hole, but may be a groove that is long in the direction perpendicular to the plane of FIG.

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, the scale removal at the joint portion between the saddle and the rest bar can be facilitated, and Maintenance management is simplified. According to the present invention, since the saddle and the guide clamp mechanism are integrated, the shift can be adjusted while the guide device is fixed at the time of shifting, and the opening and fixing work of the guide device for each shift adjustment can be omitted. In addition, the posture of the guide device can always be kept constant, and the rolled material can guide the rolled material more stably.
