Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of adjusting the clearance between two split rollers of a double-sided knowledge roller calibrator, a double-sided knowledge roller calibrator,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller calibrating machine and a roller changer of a steel forming machine, and more particularly, to a roller supporting structure of a large calibrator of both sides and a roller changer.

The roller calibrator has the structure of the rollers attached to it, and has the knowledge of both sides and the knowledge of both sides.

Since both sides of the paper have difficulty in replacing or adjusting the rollers as compared with those of the unilateral paper, it takes a long time, so most factories employ unilateral paper knowledge.

The straightening roller has been changed into a split roller type or a sleeve-fitting type so that adjustment of the hole type and replacement of the roller can be easily performed in a short time.

The roller replacement of the conventional calibrator is performed by replacing the roller unit in which the split roller is fixed to the sleeve by a spacer and fixed by a screw ring. Replacement work of the roller unit is usually carried out using a hoist or a crane, and it is possible to conduct a few persons in a short time of 30 to 40 minutes.

The common use of the rollers for various sizes is achieved by changing the position of the split rollers by changing the spacers incorporated in the sleeves of the roller unit, and recently, by using the screwed spacer and the hydraulic piston in combination, A crank method is provided for practical use, and as the mass production system of the rolling line, the improvement of the calibrating process capability is being promoted.

Japanese Patent Application Laid-Open No. 58-61922 discloses a roll changing device having a mandrel in the roll pulling direction. The roll chuck and the roll-attached sleeve are pulled out simultaneously by engaging the mandrel and the roll core, A roll exchange method and a double-sided knowledge roller calibrator which can exchange and insert sleeves are disclosed.

Japanese Utility Model Application Laid-Open No. 59-157724 discloses a method of attaching a mandrel capable of advancing and retreating in a direction orthogonal to a line of a roller calibrator and capable of adjusting its height to a running carriage, A roll set replacing device of a roller calibrator having a detachable mechanism is disclosed.

The single side ground roller calibrator has a limitation in the correcting force due to the supporting method of the roller and a high sectional modulus, but a press calibrator is used for products requiring high precision. With respect to the recent calibration work, there is a problem that the section modulus is large, the number of high-precision products increases, and the processing capability is insufficient.

In addition, in the double-sided roller calibrator disclosed in Japanese Patent Laid-Open Publication No. 58-61922, when replacing the roll-attached sleeves from the outside, the roll-attached sleeves must be suspended with a crane for exchange. Since the crane operation is included in the replacing operation, there is a problem in the efficiency of the crane operation and the safety of the operation. Further, when the roll is taken out using the mandrel, the chuck pulling out portion of the mandrel at the tip end has a complicated structure, and it takes time to engage the hook of the chuck pulling out device at the mandrel tip with the roll sleeve.

Particularly, in a large-sized calibrating machine, when a large number of replacement operations are performed, there is a problem in that the use of the crane promptly advances the operation.

The mandrel is also used in both sides of the knowledge correcting machine in Japanese Utility Model Laid-Open No. 59-157724. In order to smoothly pull out the sleeve, there is a resilience generated by the self weight of the sleeve or the like to be pulled out at this time , This resilience was interfering with the withdrawal of the sleeve. In the invention disclosed in Japanese Utility Model Laid-Open No. 57-157724, the height of the mandrel is adjusted in order to eliminate interference with drawing due to the elastic force. However, there is a limit in achieving a high degree of coaxiality between the mandrel and the roll, and it has been difficult to smoothly draw the mandrel and the roll at the time of drawing and inserting.

In addition, at the time of drawing and inserting, the mandrel slides in contact with the sleeve and the like, and therefore, wear of the mandrel has made maintenance of the mandrel important.

In the past, when the size of the section steel or the inner surface R of the section steel is changed, the rollers are replaced. That is, since the roller unit is selected in accordance with the inner surface R of the section steel and the roller unit is provided according to the size of the section steel, the roller replacement operation must be performed every time the size of the section steel or the inner surface R of the section is changed, The time required for the procedure, work, and the like when the calibration was performed.

The double-sided knowledge roller calibrator of the present invention is a high-rigidity roller calibrator by making the roller support method of both side guides, and it is possible to efficiently calibrate the section steel of large section coefficient and to calibrate the high precision.

It is possible to separate the operation-side journal unit A, the roller unit B, and the driving-side journal unit C of the both-side-edge-knowledge roller calibrator from each other by using a double- And the journal assembly, it is possible to efficiently calibrate the sections of the large section modulus and to calibrate with high accuracy, and to replace both the roller unit alone and the one set roller and the journal unit do.

And the operation-side journal unit A having the mechanism for moving the one roller unit in the axial direction of the roller can be detachably attached to each other by the two roller units B1, The position of the split roller can be arbitrarily changed, and the size of the calibrating member can be changed without replacing the rollers.

It is possible to commonly expand the rollers by configuring each of the two journal unit units A and the operation side journal unit unit A having a mechanism for moving the one roller unit in the axial direction of the roller to be engaged with the two roller units B1, , The position of the split roller can be arbitrarily changed, and the size of the calibration member can be changed without replacing the rollers.

In other words, conventionally, when the size of the section steel to be calibrated and the inner surface R of the section steel are changed, it is necessary to carry out the replacement operation of the rollers. However, since there are means for moving one roller unit in the axial direction of the rollers, And B2 can be adjusted. Even if the size of the section steel is changed, if the inner surface R of the section steel is the same, the work of correcting the section steel can be performed without replacing the roller.

The roller replacing device of the double-sided knowledge roller calibrator of the present invention is arranged in the roller axis direction from the inside to the outside of the inside of the double-sided knowledge roller straightener, the operating-side journal unit A is moved along the rails, The roller unit is loaded on one side of the traveling truck and the exchange unit is loaded on the other traveling truck and the one traveling truck is moved to the position of the other traveling truck and the replacement roller unit is moved along the rail By attaching to both side edge roller calibrators, the rollers can be easily and efficiently replaced.

One embodiment of the present invention will be described below with reference to the drawings.

FIG. 5 shows the overall front view of the large roller calibrator of the present invention, and FIG. 6 shows the entire side cross-section of the roller calibrator before its replacement, i.e. during calibration.

The roller side (shaft side) coupling of the spindle coupling 11 is held in position by the coupling clamp 12 when the roller is replaced.

Driving the roller through the spindle with the coupling holding device facilitates the replacement of a set of rollers and the journal constituent elements, and since the driving device 10 including the motor is separately installed, It becomes. Also, the roll does not bend while the roller unit is removed.

In other words, since the driving device 10 having the motor and the speed reducer has one end of the shaft of the roller and the journal structure connected by a spindle coupling and the shaft side coupling position is maintained, Since the drive device 10 including the motor is separately provided, the maintenance of the device is easily performed.

As described above, since the drive unit 10 is installed separately, it is easy to replace without interfering with the replacement. In addition, maintenance becomes easy.

Figure 1 shows a set of rollers and journal assemblies.

The separable body is mainly engaged with three constituent elements of the constitutional body: (1) the operating-side journal unit A, (2) the roller unit B, and (3)

(1) The operation-side journal unit A includes an operating-side bearing case 13 to which the wheel 14 is attached, a bearing 15, a rotary ring 17 fixed to the inner ring 16, A moving body case 19 having a groove 20 as a moving mechanism of the roller unit, a worm gear 21, a slider 22 screwed to the worm gear 21, An inner slide ring 24 having a rotation protruding portion, a slide screw ring 25 screwed to the inner slide ring 24, and a sensor 26 for confirming the movement amount.

(2) The roller unit B includes an operation-side roller unit consisting of a split roller 27, a stretching screw ring 28, a stopper ring 29, and an operation-side roller spring 30, And two roller units B1 and B2 of a drive-side roller unit including a screw ring 28, a stopper ring 29, a spacer 30, and a drive-side roller sleeve 31. [

The roller sleeve (30) of the operating-side roller unit is engaged with the roller sleeve (31) of the driving-side roller unit to constitute a set of roller units.

The operating-side roller sleeve 30 is detachably engaged with the threaded screw ring 18 and the driving-side roller sleeve 31 is detachably engaged with the inner slide ring 24.

As an example of the engagement, details of the roller unit detachable portion are shown in FIG.

The roller unit is returned to the roller shop in this state.

In other words, this roller unit is exchanged for replacing the roller in the calibrator.

In the roller shop, the split roller 27 of each roller unit is exchanged, and the position of the split roller 27 is adjusted and fixed by the spacer 30, and is brought into the set exchange apparatus in the state of FIG.

With respect to the size of the section steel which can share the split roller, when changing the size of the section steel, first, the worm gear 21 is rotated by the motor 65 and the worm 66.

The worm 66 engaged with the worm gear 21 is moved by the motor 65 in the direction of the path.

The worm gear 21 rotates in the circumferential direction of the roller by the movement of the worm 66 in the path direction. The inner surface of the worm gear 21 and the outer surface of the slider 22 are engaged with each other and the slider 22 is moved in the axial direction by the rotation of the worm gear 21.

At this time, since the slider 22 is prevented from rotating in the groove 20, it slides in the axial direction with the inner diameter of the movable body case 19 as a guide.

Simultaneously with the axial movement of the slider 22, the inner slide ring 24 connected to the slider 22 and the drive-side roller sleeve 31 connected thereto slide with the shaft 32 as a guide.

For example, in the case of changing the size from the H-shaped section 34 of FIG. 1 to the narrowed H-shaped section, since the operation side split roller 27 is fixed, the roller sleeve 31 is moved by the above- Side split roller 27 can be disposed at the dotted line position, and the distance between the roller units can be easily adjusted.

Here, it is preferable to provide a sensor 26 for detecting the amount of movement of the split roller 27 with respect to the positioning of the drive-side split roller 27.

The amount of movement of the worm gear 21, the amount of movement of the slider 22, the amount of movement of the inner slide ring 24, the amount of movement of the drive-side roller sleeve 31, The amount of movement or the like may be detected by a sensor or the like.

An example of the adjustment method at this time is shown in FIG.

The adjustment mechanism includes a section size setting section 59, a drive side split roller movement amount detection section 60, a comparison section 61, a command section 62, a worm gear rotation control section 63 and a worm gear rotation drive section 64 I have.

First, the section steel size setting section 59 inputs the section steel sizes before and after the change, and sets the movement amounts of the drive side split rollers. The drive-side split roller movement amount detection unit 60 detects the actual movement amount.

Next, the comparator 61 compares the movement amount set value obtained in the section steel size setting section 59 with the movement amount measurement value obtained in the drive-side split roller movement amount detection section 60, and transmits the comparison result to the command section 62. [

A command is given from the command section 62 to the worm gear rotation control section 63 so that the measured value of the movement amount is within the allowable range of the movement amount set value and the worm gear rotation control section 63 commands the worm gear rotation drive section 64 .

As described above, it is possible to precisely align the split roller 27 with the desired narrow width H-shaped steel calibration position by remote operation, and the roller replacement operation can be omitted.

That is, the distance between the roller units can be easily adjusted by feeding back the signal of the sensor 26 to the motor and the worm which are driving means of the driving-side roller sleeve 31.

Here, the double-sided knowledge corrector of the present invention is characterized in that a wheel is attached to each bearing case of the operating-side journal unit (A) and the driven-side journal unit (C) of the rollers and journal assemblies, It is preferable to arrange the wheel rails from the inside of the calibrator to one side of the outside of the calibrator in the direction of the straight line, and to mount the push-pull car that pulls the wheels of the bearing case of the operation-

It is preferable that the bilateral support roller calibrator of the present invention includes means for moving the roller unit between the rails in a direction perpendicular to the rails and means for supporting the roller unit, It is preferable that the bilateral support roller calibrator of the present invention is provided with a traveling truck orthogonal to the rail between the rails extending from the inside to the outside of the calibrator and the traveling truck has an elevating support for supporting the roller unit . Further, in the double-sided knowledge roller calibrator of the present invention, two traveling trucks, which divide the loading of the new roller unit and the old roller unit, are arranged in the traveling truck, and the number of roller units supported by each of the traveling trucks is divided into one .

Next, roller replacement will be described.

7 shows a side cross-sectional view of the entire roller calibrator during the replacement of the roller unit.

This is accomplished by providing an upper rail 37, a lower rail 35, two traveling trucks 36 orthogonal to each other, an upper rail 37 corresponding to each of the rollers, And a push-pull truck 38 for pulling up the operating-side journal unit A and the roller unit.

Fig. 8 shows a section of the traveling truck 35 before the roller unit is mounted, and Fig. 9 shows a section when the roller unit is mounted.

The traveling truck 35 is constituted by a roller unit pedestal 40 which is lifted and lowered by the lifting device 41 and a rail 39 inside which the lower push float 38 travels, Allows to accommodate one roller unit of the calibrator.

The replacing operation in the roller replacing apparatus configured as described above will be described in order.

Each roller in the calibrator and the journal constituent is brought to a predetermined roller replacement position and the coupling clamp 12 is closed.

The empty truck 36 is queued on the replacement line and the push-pull truck 38 is advanced to the dotted line position in FIG.

The push-pull truck 38 holds the operating-side bearing case 13 and retracts to the support position of the roller unit of the traveling truck 36 and stops on the way.

At this time, the operation-side journal unit A and the roller unit are separated from the shaft 32 in the state of FIG.

Next, the elevating device 41 of the traveling truck 36 lifts the roller unit support pedestal 40 and supports the roller unit.

The connection of the operation-side journal unit (A) and the roller unit is released, and the push-pull truck 38 retracts to the start point.

This state is shown in FIG. 7. Next, the traveling truck 36 carrying the old roller unit is traversed, and the other traveling truck 36B carrying the new roller unit is traversed to the replacement line.

The next process is the assembly of the new roller unit, but the roller replacement operation is completed by performing the reverse order of the drawing.

As described above, since one roller is replaced by a remote operation at the same time, short-time replacement is performed.

By attaching the wheels 14 to the respective bearing cases and installing the rails and push-pull trucks 38, it is easy to replace the roller units.

That is, the operating-side journal unit A and the roller unit can be pulled by the push-pull truck 38 along the rail via the wheel 14 of the bearing case and moved in the axial direction of the roller. Therefore, the replacement work can be carried out efficiently and safely, without requiring a conventional crane work.

At this time, as means for moving the operation-side journal unit A and the driving-side jug- nal unit C according to the rails, the wheel 14 is attached to the bearing case as described above, But it is also possible to move each of the bearing cases along the rails and to make a portion engaged with the rails in the bearing case and to slide the bearing case and the rails.

As described above, it is possible to easily replace the roller unit by installing a traveling truck 36 which can vertically support the roller unit and which can move up and down between the rails.

That is, the traveling truck 36 has means for orthogonally crossing the rails, means for supporting the roller unit, and means for ascending and descending. The jogging operation is carried out from the operating-side journal unit A and the roller unit The roller unit can be removed and supported, and the roller unit can be moved to another position without using a crane or the like. Further, at the time of assembling, the traveling truck 36 can be easily provided on the front face of the calibrator, and the roller unit can be easily attached to the operation-side journal unit A.

By providing a carriage supporting the one full roller unit of the calibrating machine on the traveling truck 36, simultaneous replacement of the entire roller units is possible, and the time for replacement can be shortened.

Further, by providing two traveling trucks 36 for one calibrator, it is possible to load the old and new roller units individually, and the roller unit can be continuously taken out and assembled.

That is, a new roller unit can be mounted on one traveling truck, and a new roller unit mounted on another traveling truck 36 can be mounted. Since the new roller unit is moved to the assembling position, This is possible. In addition, since the conventional crane operation is not included in the conventional art, continuous operation is possible by remote operation.

Next, the roll replacement will be described using the roll replacement portion viewed from the top of FIG.

10, an upper rail 37 orthogonal to the path direction 50 extends to one end of the outside of the straightener body 46 in the roll axis direction 51. As shown in FIG. The transverse rail 49 of the traveling truck 36 is installed in the midway of the upper rail 37 so that the transit truck 36 can move in the traveling direction 52.

The empty traveling truck 36 (for the old roller unit) is placed in the replacement line 47 and the push-pull truck 38 is advanced to the straightener body 46 along the upper rail 37. [

The push-pull truck 38 retracts from the straightener main body 46 to the supporting position of the roller unit of the traveling truck 36 while holding the operating-side bearing case, and stops in the middle.

Next, the roller unit support pedestal 40 of the transverse truck 36 is raised and the roller unit is supported.

The connection of the operation-side journal unit (A) and the roller unit is released, and the push-pull truck 38 retracts to the start point.

Next, the traveling truck 36 carrying the old roller unit is traversed to the retreating position 55, and the separate traveling truck 36B carrying the new roller unit is moved from the waiting position 54 to the replacement line 47 And traversed along the trailing rail 49 of the traveling truck.

The next step is to assemble the new roller unit. In the same manner as described above, the roller replacement operation is completed by performing the withdrawing in the reverse order.

Therefore, in the present embodiment, by providing both side edges, the shaft shaft bending is reduced, and the roller calibrator becomes a high rigidity, and the section steel of the large end face can be calibrated with high precision.

Since the roller unit is replaced, and the press calibration is not required, it is possible to reduce the equipment cost and correct the high efficiency.

The width change rate in the calibrator can be increased within a range in which the rollers can be shared, so that the number of roller replacement times is reduced.

In addition, since one unit can be replaced by the remote operation simultaneously and continuously, the replacement time can be shortened and the worker can be reduced, and replacement work can be performed without using a crane or the like, do.

As described above, it is possible to provide a large-sized roller calibrator having an enlargement of the actual calibrating operation time, that is, a large calibrating process capability.

According to the roller calibrator of the present invention, the operation-side journal unit A, the roller unit, and the driving-side journal unit C of the both-side paper roller calibrator can be separated from each other, , A pair of roller units (B1, B2) to be engaged and an operation-side journal unit (A) having a mechanism for moving one roller unit in the axial direction of the roller constitute a set of roller and journal assemblies It is possible to perform the calibration of the section steel having large face modulus and the correction of the high accuracy with high efficiency and to realize both the replacement of only the roller unit and the replacement of one set of roller and the journal constituent unit .
