JPH0614882Y2 - Roller guide for H-shaped steel rolling - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a roller guide for H-section steel rolling, which is easily attached to and detached from a rolling mill.

(Prior Art) A conventional roller guide for H-section steel is disclosed in, for example, JP-A-63-3.
This is disclosed in Japanese Patent No. 6914, in which a pair of upper and lower guides are separately attached to a rolling mill by support pins, and the vertical position adjustment of each guide moves the support pins up and down, The position adjustment of the guide in the width direction has been performed by rotating the screw spindles having mutually opposite screws to move the left and right side guide portions screwed to the spindle in the width direction.

(Problems to be solved by the invention) According to the conventional example, since the upper and lower guides have to be separately carried out when attaching and detaching the roller guides to and from the rolling mill, there is a drawback that it takes a long time to install and replace the guides. It was Further, the vertical position adjustment of the guide is performed by rotating the screw shaft to adjust the vertical position of the support pin fixed to the elevating frame via the elevating frame. Was complicated and costly. Further, since the guide is not provided with a lateral position adjusting device, for example, when the guide is not accurately centered in the lateral direction with respect to the rolling mill, the guide is moved in the lateral direction and fitted into the rolling mill. It was difficult to adjust the core.

The purpose of the present invention is to quickly install and replace a roller guide on a rolling mill, eliminate the need to adjust the position of a pair of upper and lower guides at the time of installation or replacement, and to adjust the center of the rolling mill with a simple structure. It is to provide a roller guide for H-section steel rolling that can be easily performed.

(Means for Solving the Problem) In the present invention, each pair of upper guide 4 and lower guide 5 is provided.
Are attached to the cassette box 1, the cassette box is detachably supported on the supporting portion 2 of the rolling mill, and the lateral movement bolts 19 for laterally moving the cassette box are provided on the cassette box. . Cassette box 1
The upper support shaft 6 and the lower support shaft 7 are supported by the upper support shaft 6 and the lower support shaft 7, which are eccentric shafts. The lower guide 5 is attached. A gap adjusting device for adjusting the gap between the upper guide 4 and the lower guide 5 including a worm wheel 8 provided on the upper support shaft 6 which is an eccentric shaft and a worm 9 meshing with the worm wheel 8 is provided. . Further, a pair of upper guides and a lower guide, each of which is composed of screw spindles 11 and 12 having a reverse screw relationship, and worms 13 and 14 that mesh with worm wheels 11a and 12a provided at the center of the screw spindles, respectively. A width adjusting device for adjusting the width is provided. Above upper guide 4 and lower guide 5
And a horizontal roller 17 and a vertical roller 18, respectively. The upper guide and the lower guide are provided with a follow-up device for following the rolling roll 22.

(Operation) At the same time, by mounting or replacing the cassette box 1, the mounting or replacement of the roller guide main body is performed, and by setting this cassette box on the supporting portion 2 of the rolling mill, the position adjustment of the roller guide is completed. By rotating the lateral movement bolt 19, the cassette box 1 is laterally moved, and the pair of upper and lower upper guides 4 and lower guides 5 are simultaneously laterally adjusted in position. By rotating the worm wheel 8 and the worm 9, the support shaft 6, which is an eccentric shaft, rotates to adjust the gap between the upper guide 4 and the lower guide 5. The rotation of the screw spindles 11 and 12 adjusts the widths of the pair of upper guides 4 and the lower guides 5, respectively.

(Example) An example of the present invention will be described below.

As shown in FIGS. 1 to 3, the cassette box 1 is formed in a tubular shape, and the mounting portion 1a at the bottom of the cassette box is mounted on the rest bar 2 of the rolling mill by bolts 3. As shown in FIG. 1, the inclined portion 1a1 of the mounting portion 1a is in contact with the centered inclined portion 2a1 formed in the centering portion 2a of the rest bar 2 which is the support portion. The cassette box 1 can be laterally moved by the lateral movement bolts 19 located on both sides. The outer ends of the lateral movement bolts 19 are in contact with the rolling mill. When the cassette box 1 is moved laterally, one of the left and right nuts 20 is loosened and then moved.

A pair of upper and lower upper guides 4, 4 and lower guides 5, 5 constituting the roller guide body are held inside the cassette box 1. A pair of upper guides 4
Center bracket 41 and side guide 4 in
2 and 42 are axially supported by the support shaft 6 whose shaft ends are supported on both sides of the cassette box 1, and the upper part of the center bracket is connected to the upper side of the cassette box 1 by an adjuster bolt 43. Similarly, the center bracket 51 and the side guides 52, 52 of the pair of lower guides 5 are pivotally supported by the support shaft 7 whose shaft ends are supported by both sides of the cassette box 1. The lower portion of the center bracket 51 is connected to the lower side portion of the cassette box 1 with a bolt.

The support shaft 6 is an eccentric shaft, has a worm wheel 8 at one end (the left end in FIG. 2), and a worm 9 meshes with the worm wheel. The worm 9 is attached to the worm shaft 10. Therefore, by rotating the worm shaft 10, the support shaft 6 rotates around the worm 9 and the worm wheel 8, and the gap between the upper and lower upper guides 4 and the lower guides 5 can be adjusted. Therefore, the support shaft 6, the worm wheel 8, and the worm 9 form a gap adjusting device.

The width of each pair of upper guide 4 and lower guide 5 can be changed by a width adjusting device. That is, the width adjusting device of the upper guides 4, 4, 5, 5 is provided with screw spindles 11, 11, 1 which are in a reverse screw relationship with each other.
2 and 12, worms 13 and 14 meshing with worm wheels 11a and 12a provided on the respective screw spindles, and worm shafts 15 and 16.

Therefore, when the worm shafts 15 and 16 are rotated, the screw spindles 11 and 12 are rotated and the side guides 4
2, 52 are distributed to the left and right, and the widths of the upper guides 4 and the lower guides 5 are adjusted.

Further, a horizontal roller 17 and a vertical roller 18 are provided on the upper guide 4 and the lower guide 5, respectively. The horizontal roller 17 contacts a web of H-section steel (not shown) which is a rolled material, and the vertical roller 18 contacts a flange.

As shown in FIGS. 1 and 4, the tip portion 5 a of the lower guide 5 is a follower device 21 for following the rolling roll 22.
And always comes into contact with the rolling roll 22 by its own weight.

With the above configuration, the upper guide 4 and the lower guide 5 are previously attached to the cassette box 1 at predetermined positions and the positions thereof are adjusted, and the attachment portion 1a of the cassette box 1 is placed on the rest bar 2a of the rolling mill. When it is placed and the inclined portion 1a1 is aligned with the centered inclined portion 2a1, the positioning of the roller guide with respect to the rolling roll in the front-rear direction is automatically completed, and at the same time, the positions of the upper guide 4 and the lower guide 5 are set to predetermined positions. It

(Effect of the Invention) As described above, according to the present invention, since the pair of upper and lower guides are integrally incorporated in the cassette box, when the cassette box is set on the rolling mill, the front and rear sets of the roller guides are simultaneously set. The roller guide can be installed and replaced quickly and easily. Further, it is no longer necessary to separately adjust the positions of the upper and lower guides after attaching the roller guide to the rolling mill, which is conventionally required. Further, since the lateral position of the roller guide main body can be adjusted by moving the cassette box laterally, the position adjustment can be easily performed.
