Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a side guide device used in a hot rolling equipment line or the like.

[0002]

2. Description of the Related Art In FIG. 5, reference numeral 50 denotes a roller table of a rolling equipment line; 51, a conventional side guide device provided on the line; 52, a strip which is rolled and moved on the line; The right side is shown as downstream.

[0003] The side guide device 51 comprises a pair of upstream side guides 53 whose one end on the upstream side is supported by a vertical axis 55 at a line side position and whose downstream side is freely rotatable in a horizontal plane. A pair of downstream side guides 54, one end of which is connected to the other end of the guide 53 by a vertical axis 56 and extends downstream.
And an opening / closing drive unit 57 for symmetrically moving the downstream side guide 54 in parallel in the line width direction.

The open / close drive means 57 has one end connected to the outer side of the downstream side guide 54 at the longitudinal axis 61 and the other end aligned in the width direction of the line.
A pair of linear transmission frames 63 supported by 62b
And a cross beam 64 axially connected between the pair of transmission frames 63 at right angles, and a drive cylinder 65 connected to the cross beam 64 and arranged at a fixed position.

An interlocking mechanism 70 synchronizes the linear movement of the pair of transmission frames 63. The interlocking mechanism 70 includes a rack tooth 71 provided on the upper surface of the transmission frame 63 between the slide bearings 62a and 62b, a horizontal bearing 72 provided at a fixed position in a direction parallel to the line, and a horizontal bearing rotatably supported by the horizontal bearing 72. A shaft 73 and a pair of gears (pinions) 74 fixed to both ends of the horizontal shaft 73;
4 are provided in combination with each other so as to mesh with the rack teeth 71.

As shown in FIGS. 6 and 7, in the conventional apparatus, a pair of transmission frames 63 are formed of members having a rectangular cross section, and two sets of slide bearings 62a and 62b penetrate the transmission frame 63. A bush 76 made of a copper alloy, which is in contact with the upper and lower surfaces and side surfaces of the transmission frame 63 having a rectangular cross section, is fixedly disposed in the rectangular opening 75 to support the transmission frame 63 so as to be linearly movable in the length direction.

[0007]

However, the conventional side guide device has the following problems. As described above, in the device in which the upstream side guide 53 and the downstream side guide 54 are connected by the vertical axis 56, when the downstream side guide 54 is moved in parallel by the opening / closing drive Since the upstream side guide 53 rotates following the linear movement of the transmission frame 63, an extra load is applied to the upstream transmission frame 63,
The loads applied to the upstream and downstream transmission frames 63 become unbalanced.

Therefore, the movement of the upstream transmission frame 63 tends to be delayed, and as a result, when the transmission frame 63 moves linearly as shown in FIGS. The state in which the corners of the bush 76 of the bearings 62a and 63b are rubbed is repeated, and the surface of the bush 76 is worn in a curved shape in a short period of time, causing rattling. This rattling lowers the accuracy of the width adjustment of the downstream side guide 54, and the bush 76 needs to be replaced frequently.

The interlocking mechanism 70 shown in FIG. 5 is provided to prevent a delay in the movement of the upstream transmission frame 63. That is, there is a problem that such additional facilities are required, and the side guide device 51 is enlarged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a side guide device according to the present invention will be described in detail with reference to the drawings with reference to embodiments.

Embodiment [Configuration] In FIG. 1, reference numeral 10 denotes a roller table of a rolling equipment line, 11 denotes a side guide device provided on the rolling equipment line, and 12 denotes a band which is rolled on the line and moves in the direction of the arrow. In FIG. 1, the left side is the upstream of the line, and the right side is the downstream.

The side guide device 11 includes a pair of upstream side guides 13 having one end on the upstream side supported by a vertical axis 15 at a side portion of the line and the downstream side freely rotatable in a horizontal plane.
And one end of the other end of the upstream side guide 13 on the vertical axis 1
6 and a pair of downstream side guides 14 extending to the downstream side, and opening / closing drive means 17 for moving the downstream side guides 14 symmetrically in the line width direction. The above structural units are the same as in the conventional device.

The open / close drive means 17 has one end connected to the outer side of the downstream side guide 14 at the longitudinal axis 18 and the other end aligned in the width direction of the line.
A pair of linear transmission frames 20 supported by 19b
And a cross beam 21 integrally joined at right angles between a pair of transmission frames 20, and a drive cylinder 22 connected to the cross beam 21 and arranged at a fixed position.

2 and 3, the pair of linear transmission frames 20 are constituted by members having a circular cross section of a fixed diameter.

Each of the slide bearings 19a and 19b has a built-in row of ball bearings 23 arranged in parallel with the axial direction of the transmission frame 20, and is fixedly provided on a base 24. The transmission frame 20 is in contact with the row of ball bearings 23 and slide bearings 19a, 1
9b.

As shown in FIGS. 3 and 4, the row of the ball bearings 23 may be configured as a plurality of steel ball rows 25 circulating and moving in parallel to the axial direction.

Incidentally, the pair of linear transmission frames 20 are formed of members having a rectangular cross section, and the slide bearings 19a, 19b are formed.
Can be square.

[Operation and Effect] A pair of transmission frames 20
Is supported in contact with the ball bearings 23 of the slide bearings 19a and 19b or the plurality of steel ball rows 25 circulating and moving, so that the frictional resistance when the transmission frame 20 moves is reduced. For this reason, even if an extra load is applied to the upstream transmission frame 20 by drawing the upstream side guide 13, the delay of the movement of the upstream transmission frame 20 is reduced, and the wear of the slide bearings 19 a and 19 b is reduced. Also, replacement of parts is greatly reduced.

Further, since the pair of transmission frames 20 are rigidly connected to each other integrally with the cross beam 21 or the like, the driving force in the line width direction by the driving cylinder 22 is uniformly applied to both the pair of transmission frames 20. Therefore, the downstream side guide 14 can be translated more accurately.

For this reason, the interlocking mechanism conventionally added for synchronizing the linear movement of the pair of transmission frames 20 becomes unnecessary, and the apparatus can be made compact.

It should be noted that the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the scope of the present invention.

A pair of parallel linear transmission frames connected between the motor and the opening / closing drive means and arranged to be linearly movable in the line width direction; , The frictional resistance during the movement of the transmission frame is reduced, the movement delay of the upstream transmission frame is reduced, and the wear of the slide bearing and the replacement of parts are greatly reduced.

According to the second aspect of the present invention, since the pair of transmission frames are rigidly connected to each other by a cross beam or the like and are integrally formed, the driving force in the line width direction by the driving means is a pair. It becomes evenly applied to both of the transmission frames, so that the downstream side guide can be translated more accurately. As a result, an interlocking mechanism conventionally added to synchronize the linear movement of the pair of transmission frames is not required, and the apparatus can be made compact.
