Description

Wire Rod Roll Sorting Machine {Apparatus for Arraying Wire-rod Rolling Machine}

The present invention relates to a wire rod rolling equipment aligning device, and more particularly, after the wire rod rolling roll replacement, the alignment of the rolling roll accessories such as the rolling roll and the guide on one side of the rolling roll is made precise and easy, and in particular, the pass of the rolled wire A wire rod installation aligning device for precisely adjusting line settings.

1 schematically shows a rolling and winding process of known wire rods.

That is, as shown in Figure 1, the wire-rod rolling process, the rolling material 100 heated to about 950 ~ 1100 ℃ through the heating furnace 110, for example, the cross section 160 × 160 A series of rough rolling step (120), intermediate rough rolling step 130, intermediate mirror rolling step 140, and final finishing rolling step 150, each of which has a mm in billet (B) consisting of horizontal and vertical rolling mills. Through the rolling step of the large diameter and small diameter wire rods (100 ') (100 ") is produced by rolling.

At this time, the large diameter wire rod 100 'is wound and produced through a reeler (not shown) in the intermediate sand rolling step 140, and the small diameter wire rod 100 " is passed through the finishing rolling step 150 to lay head (unsigned). It is wound through and integrated and coiled through.

Therefore, the material 110 having a rectangular cross-sectional shape extracted in the heating furnace is subjected to a rolling process of several stages, and the cross section is gradually reduced to produce a wire rod product having a diameter of a desired standard.

In this wire rod rolling process, a cutting machine 160 (for example, a crop cutting machine) for cutting the tip and the rear end of the material having a deteriorated quality and generating heat may be disposed between the respective rolling steps.

On the other hand, looking at the configuration of the rolling step in more detail, in the case of the rough rolling step as an example, as shown in Figure 2, approximately six rolling mills 210, 230, 250 may be continuously arranged, For example, the # 1,2 rolling mill 210 includes a rolling roll (unsigned) without a ball part, and the # 3,4 and # 5,6 rolling mills 230 and 250 are ball parts 232a and 252a, respectively. It can be configured to include vertical and horizontal rolling rolls (232, 252) having a (caliber).

Thus, as shown in Figure 3a, the cross section of the material is not separated by a separate sign, but the first rectangle-> oval-> circle-> collapsed oval-> collapsed circle-> more reduced oval-> further reduced As the diameter decreases in a circular step, the wire rod is rolled.

At this time, Figure 3b shows the form of the ball portion of the rolling roll according to the material rolling step by step.

Meanwhile, in FIGS. 4 and 5, as an example of the rolling mill used in the rolling step, the horizontal rolling mill 250 including the horizontal rolling roll 252 having the ball portion 252a and the guides 270 of the rolling roll in and out sides. 290 is shown.

That is, as shown in Figs. 4 and 5, the roll chocks 254 of the rolling rolls are installed in the rolling mill housing 250a, and the roll chocks and the balance cylinder 256 between the roll chokes to adjust the roll gap. It is installed via the air screw 258 on the upper roll choke side.

Therefore, as shown in FIG. 5, the pass line of the material that is press-rolled in the ball part of the rolling roll while passing through the inlet guide 270, the outlet guide 290, and the ball part 252a of the rolling roll 252, is provided with the guides. The roll balls must be aligned to match each other.

For example, in the case of the rolling roll 252 having the ball portion 252a, since the rolling is performed by gradually decreasing the diameter while passing the wire rod (material) rolled between the ball portions, the rolling roll ball portion is easily worn. Therefore, the rolling rolls are periodically replaced and repaired, and in this case, after replacing the rolling rolls, a setting operation in which the guide and the rolling roll molds are aligned with the pass line of the rolling wire is necessary.

However, in the related art, as shown in FIG. 5, the operator adjusts the rolling pass line of the rolled wire while visually confirming the pass line setting of the rolling roll mold 252a and the inlet guide 270 in the exit guide 290.

As a result, in the conventional case, since the worker aligns the entrance and exit guides 270 and 290 and the rolling roll ball part 252a with the naked eye according to the pass line during the wire rod rolling, the adjustment work takes a long time. In particular, there was a problem in that poor adjustment was easily caused.

On the other hand, as shown in Fig. 4, when aligning the positions of the balls in the rolling mill in accordance with the roll gap or the pass line of the rolling roll, it is arranged between the roll chocks 154 of the rolling roll described above provided to the housing 205a. An air screw 258 provided in the balance cylinder 256 and the upper roll choke is used.

For example, as shown in Figs. 4 and 5, in the case of adjusting the roll gap while compensating for the wear of the roll mold part, the hydraulic force is applied to the balance cylinder 256 between the roll chocks so that the upper roll choke is applied. In this state, when the air screw 258 is operated to apply a larger torque to the air screw 258 than the balance cylinder 256, the upper roll is down to reduce the roll gap, and conversely, the torque of the air screw is reduced to the balance cylinder. A smaller roll increases the roll gap.

And, as shown in Figure 5, the operator is aligned while moving the inlet guide 270 and the outlet guide 290 in accordance with the raw material pass line of the roll roll ball after adjusting the roll gap after replacement.

At this time, when adjustment of the position of the rolling roll is necessary, when the hydraulic force applied to the balance cylinder 256 is increased or decreased, the pass line adjustment of the rolling roll is performed.

However, in the conventional case, as shown in FIG. 5, since the operator adjusts the alignment of the pass line of the rolled wire, that is, the rolled roll ball part and the inlet and outlet side guides, as shown in FIG. Pass line defects generated during operation lead to severe rolling failures.

For example, as shown in FIG. 3, the horizontal rolling mill 250 horizontally moves the rolling mill housing 250a to correspond to a pass-line, and the vertical rolling mill 230 is a housing (unsigned). ), It should be set up in the pass line by moving up and down. If the adjustment of the pass line itself is poor, the horizontal mill is extracted while bending to the left and right, and collides with the exit guide 270. Cobble phenomena (Cobble) of the pass line deviation of the 290 and the rolled material is easily generated.

In addition, the curved portion of the tip of the rolled material not only collides with the inlet guide 270 of the following rolling mill, but also causes surface damage of the rolling roll, and the rolling load in the rolling roll mold also increases rapidly. Thereby rapidly expanding the wear of the roll mold.

For example, in FIG. 6A, a misalignment between the rolling roll mold 252a and the guide roll 272 of the inlet guide 270, for example, compares the cross section of the rolled material in the case where the center alignment is normal and when the abnormality is abnormal.

Thus, as shown in Figure 6a, the width of the left and right edges of the left and right edges of the normal material is constant, but in the case of abnormal material, the width of the left and right edges of the material is different to 'S1', 'S2', respectively, and eventually the next rolling mill When entering the material, the edge width is bent in a narrow direction, causing a problem of turning (Twist), such a problem is not only the impact generated when entering the material of the rolling mill inlet guide, the departure of the material from the pass line, etc. (Cobble) It is a phenomenon.

Next, in FIG. 6B, the cross-sectional view of the workpiece 232a of the rolling roll 232 of the vertical rolling mill 230 and the center alignment of the inlet guide roll 272 is normal and abnormal is shown. The upper and lower widths 'd' are equally constant, but in an abnormal case, the upper and lower widths are different from d1 and d2.

Therefore, the material is bent up and down while passing through the vertical rolling mill, and even in this case, the problems described in FIG. 6A are generated.

In addition, in the case of Figures 6a and 6b, the friction between the material and the peripheral equipment that proceeds to the material warp and scratches are formed, so that various factors that reduce the product quality, such as foreign material compression, pressing mark (roll) during rolling There is a problem of providing, in particular, there is a problem of providing other quality deterioration factors such as bursting of the material during rolling.

Accordingly, the applicant of the present invention has proposed the present invention, which facilitates the alignment of the wire rod rolls and the accompanying guide fixtures, and in particular, easy setting according to the pass line of the rolled wire rod.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

However, the configuration of the rolling mill and the entrance and exit guides in the following embodiments will be described with reference numerals of the horizontal rolling mill 250 and the entrance and exit guides 270 and 290 described in the prior art description, and will be described in detail. Is simplified in this embodiment.

In addition, it is to be understood that the wire rod rolling equipment of the present invention described in this embodiment includes an accessory equipment such as a rolling mill and a guide, and the rolling mill is not necessarily limited to the horizontal rolling mill in the embodiment.

First, Figure 7 shows the installation state of the wire rod installation equipment alignment device 1 of the present invention.

For example, as shown in FIG. 7, the wire rod rolling equipment aligning apparatus 1 of the present invention is arranged on the horizontal rolling roll 252 while corresponding to the wire rod pass line, but passes the optical signal provided to pass the optical signal for adjusting the pass line. The light emitting means 30 and the light receiving means 30 are disposed on both sides of the means 10 and the optical signal passing means 10 so as to correspond to the pass line of the rolled wire and are provided to process the optical signal passing through the optical signal passing means. It may be configured in one embodiment including a means (50).

Therefore, the wire rod rolling equipment aligning apparatus 1 of the present invention receives light from the light receiving means 50 after the optical signal LS generated by the light emitting means 30 passes through the optical signal passing means 10, thereby emitting light. If the wire pass line leading to the means 30-> rolling roll 252-> light receiving means 50 is not set precisely, that is, if the rolling roll 252 is not set in line with the pass line, the optical signal ( Since the LS is scanned by the light emitting means and blocked by the optical signal passing means 10, it cannot be delivered to the light receiving means 50 normally.

Therefore, the operator can determine that the rolling roll 252 is normally aligned with the rolling wire pass line when the optical signal reaches the light receiving means 50 normally.

On the other hand, more preferably, the light emitting means 30 and the light receiving means 50 of the present invention is disposed between the rolling roll inlet guide 270 and the rolling roll outlet guide 290, as shown in FIG. The optical signal passing means 10 is arranged between the 270 and the exit guide 290.

In this case, since the guides 270 and 290 of the rolling roll inlet and outlet sides form a passage through which the wire rod passes during rolling, as described above, the rolling roll ball part and the entrance and exit guide 270 are described. If the alignment of the 290 is not aligned in a straight line in accordance with the rolled wire pass line, the optical signal LS scanned by the light emitting means 30 interferes with any one of the exit guide, the rolling roll arrangement means, and the inlet guide. It does not reach the light receiving means 50.

6A and 6B, when the path line alignment between the inlet guide 270 and the rolling roll mold portion is substantially poor, it causes unevenness of the edge of the rolled material, as shown in FIG. 8. , The wire rod equipment aligning apparatus 1 of the present invention is arranged so that at least the optical signal LS passes through the optical signal passing means 10 and the inlet guide 270 in the light emitting means and is normally received by the light receiving means 50. It is also possible.

Of course, the arrangement of the optical signal passing means 10, the light emitting means 30 and the light receiving means 50 of the apparatus of the present invention is actually used in the setting step after replacing the rolling roll due to the wear of the rolling roll ball part, Although the means 30 and the light receiving means 50 are not shown in separate drawings, it may be preferable to use them by mounting them on a movable hanger so as to be able to adjust the position in accordance with the rolled wire pass line.

On the other hand, more preferably, as shown in Figure 8 and 9, the inlet guide disposed on the entrance or exit side of the rolling roll to the optical signal passing means 10 in the wire rod rolling equipment alignment device 1 of the present invention. One of the 270 and the outlet guide 290, preferably guided by the guide roll 272 of the inlet guide 270 is fixed to the guide fixture 70 to further pass through the additional optical signal.

Therefore, as shown in FIG. 8, the optical signal LS scanned by the light emitting means 30 in the apparatus of the present invention is not shown in FIG. 8 (290 of FIG. 7)-> optical signal passing means 10- > Guide fixture (70)-> inlet guide (270)-> the light receiving means 50 is delivered to the path, where each guide and rolling roll is normally received only when the light guide line (L) is fitted 50).

By the way, the inlet and outlet guides are easy to adjust the position as a separate component, but in the case of the rolling roll 252, as described above, the position adjustment is between the roll chocks 254 of the upper and lower rolling rolls. Of the balance cylinder 256 and the air screw 258 on the roll chocks of the upper roll.

Therefore, as shown in FIG. 7, the hydraulic supply unit U and the air supply unit AC connected to the device control unit C electrically connected to the light emitting means 30 and the light receiving means 50 are respectively. When the hydraulic pressure and air supplied to the balance cylinder 256 and the air screw 258 are adjusted to make the torque of the air screw 258 larger than the balance cylinder 256, the upper rolling roll is lowered, and vice versa. As the rolling roll rises, the roll gap is adjusted, whereby the pass line adjustment of the roll mold 252a may also be made.

At the same time, although not shown in FIG. 4, the arrangement of the rolling rolls itself may be adjusted while the housing 250a in which the rolling rolls are installed in the rolling mill 250 flows from side to side through a separate driving cylinder (not shown).

Accordingly, the device controller C determines whether the light signal is received by the light receiving means 50, and when the light signal is not received, controls the operation of the air screw, the balance cylinder, and the housing driving cylinder (not shown). The passline adjustment of the rolling rolls may be adjusted.

Meanwhile, although schematically illustrated in FIG. 7, the respective inlet and outlet guides 270 and 290 are actually installed in a separate fixed frame so that the optical signal is not transmitted to the light receiving means 50. In this case, these positions are also adjusted to adjust the position of the rolling equipment, that is, the rolling rolls and the guides, corresponding to the pass line so that the optical signal generated in the light emitting means 30 is finally transmitted to the light receiving means 50.

On the other hand, the optical signal passing means 10 in the device of the present invention in detail, as shown in Figure 8 and 9, the optical signal passing means 10, between the ball portion 252a of the rolling roll The body portion 12 is inserted into and fixed to the assembly groove portion 14 provided on one side or both sides of the guide fixture 70 is inserted into the inside of the body portion 12, and is formed through the center of the body portion It may be provided in a cylindrical shape including the optical signal passage opening 16.

Since the trunk portion 12 of the optical signal passing means 10 of the present invention is a portion that is fixedly fixed between the balls of the rolling rolls, as shown in FIGS. 7 and 9, the inner portion rounded to the circumference of the rolling rolls It is preferable to form the concave curved surface 12a.

And, as described above, the optical signal passing means 10 and the guide fixture 70 is used before the high temperature wire passes after the rolling roll replacement, so it is weak to heat rather than metal, but easy to manufacture through molding. One synthetic resin material can be made of, for example, Teflon.

That is, the optical signal passing means 10 of the present invention and the guide fixture 70 assembled thereto are in the form of the rolling roll ball part 252a (see FIG. 3B), and more preferably, the guide of the inlet guide 270. Since it is required to be manufactured in various sizes in accordance with the interval of the roll 272, it is preferable to manufacture by Teflon or the like which is easy to manufacture.

For example, FIG. 10A and FIG. 10B illustrate another form of the optical signal passing means 10 in which the guide fixture 70 according to the present invention is assembled. As shown in FIG. 10A, the optical signal passing means 10 of the present invention is illustrated. It is also possible to form a multi-faceted surface 12b on one side of the trunk portion 12 of the c) in which the rolling roll ball part is engaged and supported to keep the fixing between the rolling rolls constant.

In addition, as shown in Fig. 10b, if the shape of the rolling roll mold 252a is elliptical, as described in Figs. 2 and 3a, the body portion 12 may be formed in an elliptical shape accordingly.

And, as shown in Figure 3a, as the size of the material is reduced (reduced diameter), it is preferable that the size of the optical signal passing means 10 and the guide fixture 70 assembled thereto should also be reduced.

Of course, when setting the pass line of the rolling roll after replacing the rolling roll, the distance between balls (determining the rolling size of the actual material) can be adjusted later after adjusting the pass line, so that the optical signal passing means 10 and the guide fixture It is of course possible to make the size of 70 always have the same size (diameter) regardless of the void spacing.

At this time, as shown in Figure 9, the guide fixture 70, the assembly portion 72 is fitted to be assembled to the one side assembly groove 14 provided in the body portion 12 of the optical signal passing means, and A guide fixing portion 74 which is integrally formed in the assembly portion 72 and is inserted and fixed between the guide rolls 172 of the inlet guide of the rolling roll, and an optical signal passage hole formed in the assembly portion and the guide fixing portion ( 76) and 78).

That is, the guide fixing portion 74 is inserted and fixed between the guide rolls 272 of the inlet guide 270, the assembly portion 72 is an assembly groove portion formed in the body portion 12 of the optical signal passing means 10 Since the wire rod rolling equipment aligning device 1 of the present invention is assembled by being fitted to (14), the optical signal passing means 10 fixed to the rolling roll and the guide fixture 70 fixed to the guide roll are assembled together. Because of this, the roll roll arrangement is firm once, and at least the pass line adjustment between the inlet guide 270 and the roll roll 252 can be precisely aligned at a time.

Therefore, in the apparatus of the present invention, the optical signal LS scanned by the light emitting means 30 is consequently assembled into one side groove 14 of the optical signal passing means 10-> optical signal passage 16-> the other side. The optical signal passages 76 and 78 of the guide fixture 70 and the guide fixture 74 of the guide fixture 70 assembled in the assembly groove 14 are transferred to the path of the light receiving means 50. In the meantime, when the optical signal reception at the light receiving means 50 is normally performed, it may be understood that the alignment of the rolled roll and the accessory equipment such as the guide is normally adjusted in the rolled wire pass line.

On the other hand, as shown in Figures 7 and 8, the light emitting means 30 of the present invention is preferably provided with a laser generator for generating a laser beam which is a straight optical signal, the light receiving means 50 is a laser beam It may be provided as a receiver.

Such laser generators and laser beam receivers are known. However, this is only one example, and it is of course possible to use a light emitter and a light receiver for generating an optical signal such as ultraviolet light.

At this time, more preferably, although not separately shown in the drawing, an optical signal LS, such as a laser beam, is condensed by condensing an optical signal in front of the light emitting means 30 to guide the optical signal passing means 10 and the guide of the apparatus of the present invention. The condenser 70 and a condenser lens (not shown) for more uniformly passing through the guides 270 and 290 are arranged.

On the other hand, as shown in FIG. 8, when the input device IN (for example, a personal computer) gives a command to the device controller C, the device controller C controls the operation of the laser generator, which is the light emitting means 30, At this time, when the alignment of the guides 270 and 290 and the rolling roll 252 is adjusted in response to the normal pass line, the optical signal, that is, the laser beam, is normally received by the laser receiver, which is the light receiving means 50.

At this time, the device control unit C, which is connected to the light receiving means, that is, the laser beam receiver, informs that the light signal is normally received by the output device OUT (for example, a display unit, a lamp, etc.).

If such a normal light signal is not received, that is, the alignment between the guides and the rolling roll is poor and the light signal is not received, the operator adjusts the position of the guides and the rolling roll as described above. Is adjusted repeatedly to match the pass line of the rolled wire.

On the other hand, the apparatus of the present invention to confirm that the rolling roll ball portion 252a is worn and the material sag due to the repeated processing occurs.

That is, as shown in Figure 7, the upper and lower rolling portion of the roll 252a wears in contact with the material as it is rolled, and thus, if the ball is repeatedly processed through periodic rolling roll maintenance, The deflection of the material in the mold portion through which is passed is generated, and this deflection compensation can be easily corrected using the apparatus of the present invention.

While the invention has been shown and described in connection with specific embodiments so far, it will be appreciated that the invention can be varied and modified without departing from the spirit or scope of the invention as set forth in the claims below.
