BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gap adjusting device for an outlet guide for rolling, and more specifically, a pair of guide members spaced apart in a direction intersecting a feeding direction of a material to be rolled on a downstream side of a rolling mill. The present invention relates to a gap adjusting device for adjusting a gap between the guide members in accordance with a dimension of the material to be rolled in an outlet guide for rolling which surely guides the material to be rolled from the rolling mill by both guide members.

[0002]

2. Description of the Related Art A rolling mill for rolling a material to be rolled having a circular or rectangular cross section into a desired cross sectional shape is vertically opposed to each other with a pass line PL of the material to be rolled W interposed therebetween, as shown in FIG. The rolling rolls 10 and 11 are rotatably provided, and the material W to be rolled is clamped and fed by both rolls 10 and 11 rotating in opposite directions to perform a required rolling. In this rolling mill 12, the tip of the rolled material W to be rolled may be torn as shown in FIG. 11, and this may occur on the outer peripheries of the upper and lower rolling rolls 10 and 11 as shown by the chain double-dashed line. There was a serious problem that winding and feeding to the downstream side became impossible and rolling was impossible in the rolling mill 12. Further, as shown in FIG. 12, due to plastic deformation, the tip of the material W to be rolled is bent, such as warped.
There is also a problem that the material W to be rolled is not fed horizontally to the downstream side of No. 2 and the processing on the downstream side is hindered. Therefore, the pass line P of the material W to be rolled is provided on the downstream side of the rolling mill 12.
A pair of guide members 13 and 14 that vertically face each other with L interposed therebetween.
The exit guide 15 for rolling equipped with
The material W to be rolled is guided horizontally from the rolling mill 12 via the roller 5.

Further, in the rolling mill 12, the upper rolling roll 10 is configured to be movable toward and away from the lower rolling roll 11 so as to adjust the amount of reduction according to the size of the material W to be rolled. It is configured. Therefore, the size of the material W to be rolled out sent from the rolling mill 12 differs depending on each order, and in order to reliably derive the material W to be rolled after rolling, the interval between the pair of guide members 13 and 14 is set to the material W to be rolled.
It was necessary to adjust according to the dimensions of.

FIG. 13 shows an example of a rolling outlet guide 15 having a gap adjusting function. The material W to be rolled is fed to the downstream side of the rolling mill 12 corresponding to the lower rolling roll 11. Lower guide member 1 extending in a predetermined direction
4 is positioned and fixed in parallel with the pass line PL of the material W to be rolled, and the tip end portion that points upstream thereof is brought into sliding contact with the outer circumference of the lower rolling roll 11. Further, the material W to be rolled is provided on the downstream side of the rolling mill 12 corresponding to the upper rolling roll 10.
An upper guide member 13 extending in a predetermined length in the sheet feeding direction is disposed. The upper guide member 13 has its downstream end rotatably supported by a frame (not shown) via a pin 16 and has a tension spring 17 stretched between the upstream end and the frame near the upstream end. Always urged upward. That is, the upper guide member 13 is biased so that the tip end portion that points upstream thereof is always in sliding contact with the outer circumference of the upper rolling roll 10, and the upper rolling roll 10 is moved up and down for adjusting the reduction amount. The upper guide member 13 rotates about the pin 16 as a fulcrum following the movement of the lower guide member 1
The distance from 4 is adjusted.

FIG. 14 shows another example of the rolling outlet guide 15 having a gap adjusting function.
The lower guide member 14 is installed between the lower chocks 18, 18 (only one of which is shown) rotatably supporting the lower rolling roll 11 in FIG. An upper guide member 13 is installed between the upper chocks 19 and 19 (only one is shown).
As a result, as the upper rolling roll 10 is moved up and down to adjust the reduction amount, the upper guide member 13 also moves integrally, and the distance between the upper guide member 13 and the lower guide member 14 is adjusted.

[0006]

In the rolling outlet guide 15 shown in FIG. 13, since the upper guide member 13 rotates about the pin 16 as a fulcrum, when the adjustment amount of the upper rolling roll 10 becomes large, the upper guide member 13 is rotated. 13 is inclined with respect to the pass line PL of the material to be rolled W (state shown by the solid line in FIG. 13), and the material to be rolled W sent from the rolling mill 12
It is pointed out that there is a difficulty that it will not be possible to guide horizontally. Further, since the upper guide member 13 is only supported through the pin 16, the pin W is caused by the stress applied when the material W to be rolled whose tip is torn or bent slides along the guide members 13 and 14. There was a problem that 16 was damaged.

In the rolling outlet guide 15 shown in FIG.
Since the upper guide member 13 moves in parallel as the upper rolling roll 10 moves up and down, the guide member 13 can always be held in parallel with the pass line PL. In this case, in the material W to be rolled, the width direction (rolling rolls 10, 1
In order to prevent deviation of the guide member 1 in the axial direction (1), both guide members 1
In some cases, it may be necessary to provide a width guide (not shown) orthogonal to 3,14. However, in the configuration of FIG. 14, since both guide members 13 and 14 exist over the entire length in the axial direction of the rolling rolls 10 and 11, it is extremely difficult to dispose the width guide of the material W to be rolled, There was a drawback that the possible rolling mill 12 was limited.

[0008]

There is. Further, in FIG. 1, reference numeral 26 indicates a pulley rotatably arranged on the upstream end side of the frame 21, and the wire rope 25 is wound around the pulley 26 so as to move smoothly.

As shown in FIG. 5, the gap adjusting device 20 arranged on the frame 21 separates the upstream front plate 27 and the downstream rear plate 28 by a predetermined distance via spacers 29, 29. The main body 30 is fixed to the frame 21 via a plurality of bolts 31. Front plate 2
In the space defined between 7 and the rear plate 28, as shown in FIG.
As shown in FIG. 3, a holder 32 is vertically movably disposed at the center of the main body 30 in the width direction (direction intersecting the feeding direction of the material W to be rolled), and the holder 32 has a lower portion extending downward from the main body 30. The downstream end of the upper guide member 13 is rotatably supported by the formed bifurcated portion 32a via a pin 33. On both sides in the width direction of the upper part of the holder 32 facing the inside of the main body,
Extending portions 34 and 35 extending in mutually opposite directions are formed, and both extending portions 34 and 35 are connected to elevating mechanisms 36 and 37 arranged on both left and right sides in the width direction with the holder 32 sandwiched therebetween. ing. Since the configurations of the left and right elevating mechanisms 36 and 37 are symmetrical, only the configuration of the right elevating mechanism 36 in FIG. 4 will be described, and the same members of the other elevating mechanism 37 are designated by the same reference numerals. I will.

Above the holder 32, the material W to be rolled is placed.
An operating shaft 38 that intersects the feeding direction of the frame is rotatably supported by the main body 30, and the operating shaft 38 is connected to the frame 21.
Is connected via a universal joint 41 to a drive shaft 40 which is rotated by a hydraulic motor 39 as a drive means arranged in (1) (see FIG. 2). A pair of worms 42, 42 constituting the left and right elevating mechanisms 36, 37 are arranged on the operating shaft 38 so as to rotate integrally with each other at a predetermined distance in the axial direction. The twisting directions of the worms 42, 42 are set to be opposite to each other.

A right worm wheel 43, which is a fan-shaped adjusting member that meshes with the right worm 42, is rotatably disposed between the front plate 27 and the rear plate 28. Is an extension portion 43 extending in the radial direction.
a is formed. A pin 44 having a large-diameter head portion 44a is fitted to the extending portion 43a in a state where the large-diameter head portion 44a is projected to the upstream side (front plate side) in the material feeding direction as shown in FIG. Has been inserted. A pin 45 having a large-diameter head portion 45a is also inserted into the right extending portion 34 of the holder 32 with the large-diameter head portion 45a protruding toward the upstream side in the material feeding direction. Further, between the front plate 27 and the rear plate 28, two through holes 46a,
A link plate 46 having a hole 46b is loosely fitted therein, and the large-diameter head 4 of the pin 44 is inserted into one through hole 46a of the link plate 46.
4a is rotatably fitted and the other through hole 46b
A large-diameter head portion 45a of the pin 45 is rotatably fitted in. That is, when the actuating shaft 38 is rotated in the forward and reverse directions, the left and right worm wheels 43, 43 meshing with the left and right worms 42, 42 are rotated in opposite directions to each other.
Further, as shown in FIG. 9, the holder 32 connected by the left and right link plates 46, 46 is moved up and down.

The outer circumference of the large-diameter head portion 45a of the pin 45 projecting from the right extending portion 34 of the holder 32 is inclined so that the diameter decreases from the rear side toward the front and rear sides. The holder 32 and the pin 45 are the link plate 4
It is configured so that it can be easily removed from 6 to the rear surface side (downstream side in the material feeding direction) (see FIG. 10).

As shown in FIG. 7, the rear surface of the link plate 46, which faces the rear surface plate 27, is provided with a supporting portion 47 projecting toward the rear surface at a position facing between the through holes 46a and 46b. ing. The surface of the support portion 47 corresponding to both the through holes 46a and 46b is formed in an arc shape, and the arc-shaped guide surfaces 47a and 47a are formed.
Further, the arc-shaped outer peripheral portion of the extending portion 43a of the right worm wheel 43 and the arc-shaped outer peripheral portion of the right extending portion 34 of the holder 32 slidably abut. The arc-shaped guide surface 4 of the support portion 47
As shown in FIGS. 8A and 9A, 7a and 47a and the respective extending portions 43a and 34 are set so as to always contact each other even when the holder 32 moves up and down. That is, the link plate 4
6 to holder 32 and right worm wheel 43
Not only the large-diameter head portions 44a and 45a of the pins 44 and 45 but also the extended portions 34 and 43a and the support portion 47 are in contact with each other, and the stress applied via the upper guide member 13 can be received in a wide area. You can do it.

Here, when the material W to be rolled is rolled by the rolling mill 12, if the size (thickness) is large, the degree of bending due to plastic deformation is small, and the smaller the size (thickness), the greater the degree of bending. . That is, the stress applied to the upper guide member 13 that guides the material W to be rolled increases as the size of the material W to be rolled increases. In Therefore EXAMPLE spacing device 20, when the upper guide member 13 most lowered to (distance between the lower guide member 14 is minimum) was, as shown in FIG. 5, the axis P ₁ of the worm wheel 43, the wheel The axis P ₂ of the pin 44 arranged in the extending portion 43a of the pin 43 and the axis P ₃ of the pin 45 arranged in the extending portion 34 of the holder 32 are set to be linearly aligned. Moreover, the center lines passing through the respective axial centers P ₁ , P ₂ , P ₃ of the left and right lifting mechanisms 36, 37 are arranged on the holder 32.
It is set to intersect at the widthwise center of. As a result, the holder 32 and the elevating mechanism 3 are inserted through the upper guide member 13.
The stress applied to the connecting portion with 6, 37 acts linearly to improve the strength of the elevating mechanisms 36, 37 against the stress.

A rectangular notch 28a is formed in the widthwise center of the rear plate 28, and a lid plate 48 for supporting the rear surface of the holder 32 is fitted in the notch 28a. This lid plate 4
8 is formed in a rectangular plate shape, and a taper surface 48a that is inclined downward from the front surface side toward the rear surface side is formed at the upper end portion thereof, as shown in FIG. Further, a tapered surface 28b corresponding to the tapered surface 48a is formed at a lower end portion of the notch 28a of the rear surface plate 28 corresponding to the tapered surface 48a of the lid plate 48.
The cover plate 48 is fitted into the notch 28a in a state in which b is abutted. The lower portion of the cover plate 48 is inserted into both sides of the holder 32 in the width direction, and is fixed to the front plate 27 by bolts 50, 50 screwed into nuts 49, 49 corresponding to the front plate 27. There is. The lid plate 48 supporting the rear surface of the holder 32 is separated from the main body 30 together with the holder 32 when the material W to be rolled collides with the tip of the upper guide member 13 and an extremely large stress is applied to the lid plate 48. It is configured to prevent the main body side of the device 20 from being damaged due to a large stress.

An encoder 51 is connected to the drive shaft 40 rotated by the hydraulic motor 39, and the encoder 5
The position of the upper guide member 13 is detected from the rotation angle of the drive shaft 40 detected by 1.
Then, the detection signal from the encoder 51 is adapted to be input to a control means (not shown) including a microcomputer, for example. Therefore, by inputting the reduction amount data of the upper rolling roll 10 to the control means, the upper guide member 13 is correspondingly moved up and down as the rolling roll 10 moves up and down, and the guide member 13 is rolled. It is possible to always keep the posture in parallel with the pass line PL.

[0022]

Next, the operation of the gap adjusting device according to the embodiment constructed as described above will be described. The upper guide member 13 is positioned at the lowest position in accordance with the material W to be rolled having a small size, as shown in FIGS. 8 (a) and 8 (b), and the space between the upper guide member 13 and the lower guide member 14 is minimized. It is supposed to be set.

In this state, the material W to be rolled, which has been rolled by the rolling mill 12 and sent to the downstream side, has the upper guide member 13 and the lower guide member 1 in the rolling exit guide 15.
It is introduced between 4 and. Since both guide members 13 and 14 are both held parallel to the pass line PL of the material W to be rolled, the material W to be rolled whose tip is torn or bent due to plastic deformation is ensured horizontally in the downstream side. Can be derived to.

As described above, the material W to be rolled has a small size.
In the case of 1, the bending due to plastic deformation is large, and the material W passes while being pressed against the upper guide member 13 with a large force. In this case, the left and right extending portions 34 and 35 of the holder 32 and the link plates 46 and 46 are
The pin 45 is not damaged because it is supported by abutting against the pin 5 and the supporting portion 47. Moreover, the axis P ₁ of the worm wheel 43 of the left and right lifting mechanisms 36, 37, the axis P ₂ of the pin 44 of the wheel 43, and the axis P ₃ of the pin 45 of the holder 32 are aligned linearly. Therefore, the stress applied from the material W to be rolled is determined by the holder 32 and the lifting mechanism 36, 3
It acts linearly on the connecting portion with 7, and the lifting mechanism 36, 37 can sufficiently receive the stress.

Further, the upper guide member 13 may be worn out and become brittle with time, and the tip end portion which comes into sliding contact with the upper rolling roll 10 may be damaged. Since the tip of the upper guide member 13 faces the inside of the rolling mill 12, it is difficult to confirm the state from the outside. If the tip is operating with the tip damaged, the tip of the material W to be rolled is Collides with the tip of the upper guide member 13 from the feeding direction, and extremely excessive stress is applied.
In this case, the holder 32 that supports the upper guide plate 13
Is only detachably connected to the link plates 46, 46 via the pins 45, 45, and the cover plate 48 supporting the rear surface of the holder 32 has two bolts 50, 50.
It is fixed to the front plate 27 only. Therefore, when an extremely large amount of stress is applied to the holder 32 via the upper guide member 13, the holder 32 is disengaged from the link plates 46, 46 and the bolts 50, 50 are tightened by the nuts 49, 50 as shown in FIG. The cover plate 48 is detached from the front plate 27 rearward from the front plate 27. As a result, it is possible to prevent a large stress from being applied to the main body side of the space adjusting device 20, and to minimize the damage.

Next, when the size of the material W to be rolled becomes large due to the order change or the like, the upper rolling roll 10 of the rolling mill 12 is raised by the required amount by the reduction amount adjusting mechanism, and at the same time the roll 10 is rolled up. The upper guide member 13 is also raised by an amount corresponding to the amount of rise. That is, the hydraulic motor 3
9, the operating shaft 38 is rotated in the required direction via the drive shaft 40, and the left and right worms 42 disposed on the operating shaft 38,
The left and right worm wheels 43, 43 meshing with 42 rotate in mutually opposite directions to lift the link plates 46, 46. Therefore, the holder 32 connected to the link plates 46, 46 rises as shown in FIGS. 9A and 9B, and the downstream side of the upper guide member 13 rises. The upper guide member 1
The upstream side of No. 3 is always urged by the elasticity of the coil springs 23, 23 in the direction of sliding contact with the outer circumference of the upper rolling roll 10, so that it moves upward as the upper rolling roll 10 moves upward, whereby the upper guide The member 13 rises while maintaining a parallel relationship with the pass line PL. Therefore, the material W to be rolled having the dimension after the order change is introduced from the rolling mill 12 between the adjusted guide members 13 and 14 and is reliably guided in the horizontal state.

In the embodiment, the case where only the upper guide member 13 is moved up and down as the upper rolling roll 10 is moved up and down has been described, but the present invention is not limited to this.
When both the upper and lower rolling rolls 10 and 11 of the rolling mill 12 are configured to be movable toward and away from the pass line PL, the upper and lower guide members 13 and 1 are correspondingly provided.
Both 4 can be moved up and down by the space adjusting devices 20, 20. In addition, in the embodiment, the rolling rolls 1 that are horizontal in the vertical direction sandwiching the pass line PL of the material W to be rolled.
The case in which the rolling outlet guide 15 is provided on the downstream side of the rolling mill 12 having 0 and 11 has been described, but the rolling outlet guide is provided on the downstream side of the rolling mill having the vertical rolling rolls. The interval adjusting device of the present application can be adopted.

[0028]

As described above, according to the gap adjusting device for the exit guide for rolling according to the present invention, the guide member can be moved in parallel in response to the movement of the rolling roll in the rolling mill. The material to be rolled can always be held parallel to the pass line, and the material to be rolled can be reliably guided out in a horizontal state from the rolling mill. In addition, the strength against the stress applied from the material to be rolled is high, and accurate distance adjustment can be performed over a long period of time. Further, when the material to be rolled collides with the upstream end of the guide member and an extremely large stress is applied, the holder and the lid plate supporting the guide member are disengaged from the main body to the downstream side, and a large stress is applied to the main body side. Can be prevented and the damage can be limited to the minimum required.

Further, since the guide member is configured to be moved up and down by the link mechanism, the apparatus can be made compact and the opening adjusting device can be arranged in a limited small space on the downstream side of the rolling mill.
