Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention applies welding buildup or thermal spraying buildup to table rolls of various transport tables (roller tables, roller conveyors, etc.) on site (on site), and then polishes the buildup part. The present invention relates to a roll polishing apparatus used for finishing or for polishing finish repair of flaws on roll surface.

[0002]

2. Description of the Related Art In a roller table or the like of a rolling line, when the outer peripheral surface of a table roll is worn or scratched,
There are a method of removing the table roll body and repairing it at another place where repair equipment is provided, and a method of repairing it on the spot without removing the roll.

Since the former method has a drawback that it takes time and trouble to remove and reassemble the roll, the latter method has been adopted. In this field repair,
When the outer peripheral surface of the roll is worn, the welding target or the thermal spraying is applied while rotating the repair target roll at a low speed. Although it depends on this build-up condition, it is usually necessary to finish the build-up portion, and in the past, a worker uses a sander (polishing disc, polishing belt, etc.) or the like to perform polishing.

[0004]

The polishing and finishing work with this sander is related to the partial polishing and finishing work.
The apparatus is also compact and convenient, but when the polishing work for polishing the roll wear portion is performed, the polishing finish surface also becomes wide, and in most cases, it is the entire circumference of the roll over a certain range of a part of the roll cylinder length. In spite of such a wide range of polishing finish, in the past, it was the actual situation that the worker did the sanding polishing finish while directly turning the roll, and the polishing allowance and polishing range were not constant due to manual work, and the finish The condition is not good, and the roll cylindricity after polishing is also broken.

Further, due to the welding build-up with improved wear resistance and the increase in surplus allowance with emphasis on the finished surface, the polishing and finishing work time and the work load on workers are further increased.

Incidentally, Japanese Patent Laid-Open No. 3-71978 discloses that
It is described that after automatic overlay welding is performed on a repaired portion of the table roll, this portion is ground and finished by a dedicated grinding device. This grinding machine, as shown in FIG.
A machine body A having wheels B at both ends is provided with a grindstone C, a grindstone rotating motor D, a belt transmission mechanism E, a handle F, and the like.
It is configured to move in the roll axial direction across the repair target roll R.

However, in such a grinding machine,
Since it is not possible to adjust the vertical position with respect to the grinding part, it is not possible to obtain an appropriate polishing force corresponding to the state of the finished surface, roll material, grinding stone material, etc. Also, it is not possible to set the polishing allowance, so it is highly accurate Roll cylindricity and finished surface cannot be obtained. Further, since the worker moves the apparatus main body, stable grinding feed cannot be performed in the roll axis direction.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to grind a build-up portion or a flaw portion while rotating the table roll on the spot without removing the table roll. The main body can be easily and accurately positioned and fixed to the side of the roll to be polished and repaired, and the polishing force and polishing allowance can be easily set and adjusted, resulting in a roll cylindricity and finished surface that are more accurate than manual finishing. In addition to being able to obtain a large amount of work efficiency, it is possible to perform a stable polishing feed in the axial direction of the roll, and a table roll site that is a relatively simple and compact device. It is to provide a roll polishing device for repair.

[0009]

SUMMARY OF THE INVENTION The present invention is a roll polishing device for polishing and finishing a roll roll outer peripheral surface by welding or thermal spraying, a buildup portion, a flawed portion, or the like when the table roll is locally repaired. , A device base that is installed on the side of the table roll to be polished and repaired in the table conveying direction and is movable and fixable to the roll to be polished and repaired, and can be vertically swung about a fulcrum on this device mount. The oscillating frame, which is attached and is capable of adjusting the grinder's polishing force and the amount of polishing finish for the roll to be polished and repaired, and the grinder traverse mechanism installed in this oscillating frame, enable lateral movement. A grinder grindstone is attached to the tip part and a grinder mount having a grindstone rotation motor at the base end part.

When there is an apron plate between the table rolls, the apparatus stand is provided with a wheel for moving the apparatus having a structure capable of ascending and descending and a magnet for fixing the apparatus in a fixed arrangement in the lower part. The lowered device moving wheel moves on the apron plate to position the device main body with respect to the roll to be polished and repaired, then the device moving wheel is raised and the device fixing magnet fixes the device main body to the apron plate. . When there is no apron plate, for example, the device stand is fixed to a plurality of table rolls other than the roll subject to polishing repair by a device fixing magnet, and the upper part of the device stand can be moved back and forth with respect to the roll subject to polishing repair.

The grinder lateral feed mechanism is composed of, for example, a lateral feed screw shaft and a guide rod arranged in a swing frame in a direction orthogonal to the movement direction of the apparatus frame, and the lateral feed screw shaft is screwed to the base of the grinder frame. At the same time, the guide rod is inserted and the lateral feed screw shaft is rotated by a handle or a motor, so that the grinder base can be moved along the roll axis direction. The glider grindstone is mounted so that its grindstone axis is parallel to the roll axis.

The grinder grinding force varying mechanism for adjusting the grinding force of the grinder grindstone with respect to the roll to be ground and repaired includes, for example, forming a large number of screw holes of bolts for attaching the fulcrum shaft and the fulcrum bearing to the swing frame and the apparatus frame, respectively. Then, the mounting position of the fulcrum shaft or the fulcrum bearing is made variable. By moving the fulcrum position, the relationship between the position of the center of gravity and the fulcrum position above the swing frame changes, and the pressing force of the grinder grindstone can be changed. Further, this grinder polishing force varying mechanism may be balance weights of various weights which are detachably attached to the tip end portion of the grinder stand, and can be used together with the fulcrum moving grinder polishing force varying mechanism.

The polishing finish amount setting adjusting mechanism is provided, for example, at a rear end portion of the device base opposite to the grindstone, and has a screw shaft protruding through the swing frame and screwed to the screw shaft.
It is composed of a double nut, a handle, or other polishing finishing amount setting adjusting member that prevents the swinging movement of the swinging frame from rising. The swing frame that swings up and down around the fulcrum is
The rear end of the oscillating frame rises from the almost horizontal state at the start of polishing, but if a gap is provided between the lower surface of the double nut and the upper surface of the oscillating frame at the start of polishing, a grinder can be used. When the grindstone descends to reach a predetermined grinding allowance, the lower surface of the double nut contacts the upper surface of the swing frame, and the descending of the grinder grindstone is stopped.

To rotate the roll to be polished at the time of polishing, an existing rotary drive device connected to the table roll, manually rotated by an operator, or a simple roll rotary device other than the existing rotary drive device is used.

[0015]

In the above construction, when the apron plate is provided between the rolls and the vertically movable device moving wheels and the device fixing magnet are used, the device body is laterally moved in the table conveying direction of the roll to be polished and repaired. Place it on the apron plate and move the device body with the lowered wheel to position it so that the grindstone is located right above the polishing location of the roll to be repaired, then raise the wheel and secure it with a magnet. To do. As a result, the grindstone can be easily and accurately positioned and fixed on the polishing portion. At this time, by arranging the grindstone axis of the grindstone parallel to the central axis of the roll to be polished and repaired, it is possible to improve the polishing accuracy in the roll axial direction.

At the time of positioning and fixing, the tip of the swing frame, that is, the grindstone is raised by lowering the polishing finish amount setting adjusting member such as a double nut.
In this state, the roll to be polished and repaired and the grindstone are rotated. Next, the grinding stone is lowered by raising the polishing finish amount setting adjusting member to start polishing. At the same time, the polishing finish amount setting adjusting member is further raised to set the polishing finish amount in consideration of the polishing allowance and the grindstone wear amount. When a predetermined polishing allowance is obtained, the upper surface of the swing frame contacts the lower surface of the polishing finish amount setting adjusting member, and the lowering of the grindstone automatically stops. As a result, over-polishing by hand is eliminated, more accurate roll cylindricity and finished surface can be obtained compared with hand finishing, and work efficiency is also improved. Further, when the roll rotation device is used, the worker only needs to monitor the device, and the load on the worker is greatly reduced.

The polishing force can be adjusted by changing the fulcrum position or changing the balance weight. Even if the condition of the finished surface, the material of the roll, the material of the grindstone, etc. changes, the polishing power is always adjusted to the optimum value. Therefore, it is possible to obtain more accurate roll cylindricity and finished surface. Further, during polishing, even if there are projections or the like on the polishing surface, the grindstone can rise and escape centering on the fulcrum, so that the grindstone can be prevented from being broken due to overload.

When the polishing surface is wider than the width of the grindstone, the grinder base can be stably moved manually or automatically in the roll axial direction by the transverse feed mechanism, which is more accurate than the manual finishing. The degree and finish can be obtained, and the work efficiency is improved.

During build-up welding or thermal spraying and subsequent polishing according to the present invention, it is necessary to rotate the table roll R. For this rotation, an existing roll rotation drive device connected to the table roll is used. Method using
It is possible to employ a method in which the worker directly turns the hand, or a method in which a simple roll rotation device other than the roll rotation drive device is used.

Although any of the above-mentioned methods may be adopted, from the viewpoint of safety and work load, and because the rotation speed of the existing rotary drive device is generally high and not suitable for repair, it is relatively simple and relatively slow. Roll rotators are preferred. This simple roll rotating device is a “roll rotating device for on-site repair of table roll” which the applicant of the present invention has already filed (Japanese Patent Application No. 5-4624).
No. 8) is the most suitable.

FIG. 7 shows an example of this simple roll rotating device. The simple roll rotating device 100 is an endless device stand 101 having a shape straddling the table roll R, the table roll R and the drive pulley 103. A belt 102 that is wound around and detachable with a fitting, and a drive pulley 10
An electric motor 104 and a speed reducer 105 that rotate and drive the motor 3,
It is composed of a tensioner 106 that applies tension to the belt 102. With such a device, the belt can absorb rattling of the apron plate and the like, and the rotational force can be reliably transmitted to the table roll R, so that stable low-speed repair rotation can be obtained.

With the above structure, the on-site polishing is performed as follows.

(1) The apparatus base 2 is placed on the apron plate P while the wheels 11 are being lowered and clamped. Here, before or after the placement, the mounting position of the fulcrum shaft 20 or the fulcrum bearing 21 is changed or the balance weight 22 of the balance weight 22 is changed according to the state of the finished surface of the roll to be polished and repaired, the roll material, the grindstone material, and the like. The pressing force of the grindstone 5 is adjusted by changing the weight.

(2) The apparatus base 2 is moved to the welded or sprayed buildup portion of the roll R to be repaired, or a portion with a flaw, and the grindstone shaft 50a is positioned parallel to the central axis of the table roll P and directly above it. To do so. In this example,
The main body of the device has a length of 1 m or less and a weight of more than 150 kg, and can be easily positioned.

(3) The wheel 12 is removed and the wheel 11 is raised and retracted to bring the magnet 12 into contact with the upper surface of the apron plate P and transfer the support of the apparatus main body to the magnet 12. At this time, the double nut 31 is lowered and the whetstone 5 is raised so that the whetstone 5 does not contact the table roll R.

(4) The magnet 12 is turned on, and the excited magnet 12 fixes the apparatus main body to the apron plate P. In this state, the table roll R is manually rotated, or is rotated at a low speed by the above-described simple roll rotation device 100.

(5) The grindstone 5 is rotated by the motor 6, and the double nut 31 is raised to lower the grindstone 5,
Polishing is started when the grindstone 5 contacts the upper surface of the table roll P. While the swing frame 3 is held substantially horizontally by the grindstone 5, the double nut 31 is further raised to provide a gap between the upper surface of the swing frame 3 and the lower surface of the double nut 31. This interval is determined in consideration of the stock removal and the grindstone wear amount (see FIG. 6). (6) When the grinding progresses and the grindstone 5 reaches the set grinding amount, the upper surface of the swing frame 3 contacts the lower surface of the double nut 31, and the grindstone 5 does not descend below this.

Since the polishing is automatically completed when the desired polishing amount is reached, when the table roll R is rotated by the simple roll rotating device, the operator need only monitor the grinder device.

(7) When the grinding surface is wider than the grindstone width, the same grinding as described above is carried out while the lateral feed handle 42 is turned to feed and move the grindstone 5 in the roll axis direction.

(8) When the polishing finish is completed, the rotation of the grindstone 5 is stopped, and the double nut 31 is lowered to raise the grindstone 5. Next, the attraction of the magnet 12 is released, the wheel 11 is lowered / clamped, and the apparatus main body is moved to the next polishing position.

Although the example applied to the roller apron of the rolling line has been described above, it is needless to say that the present invention can be applied not only to this but also to the on-site polishing of other roller conveyors. If there is no apron plate, the rolls other than the roll to be polished and repaired are fixedly supported by magnets so that the upper part of the device stand can be moved back and forth toward the rolls.

[0049]

As described above, in the roll polishing apparatus according to the present invention, the swing frame can be vertically swung about the fulcrum on the apparatus stand which is movable and fixed to the roll to be polished and repaired. Since the grinder frame is installed and provided on the swing frame so as to be laterally movable via the lateral feed mechanism, the following effects are achieved.

(1) When polishing the build-up portion or the flaw portion while rotating the table roll on the spot without removing it, the grinder is polished by moving and fixing the device base on the side of the roll to be polished and repaired. It can be easily and accurately positioned and fixed on the spot.

(2) Since the lowering of the grindstone is automatically stopped by the polishing finishing amount setting adjusting member, over-polishing by the conventional manual work is eliminated, and the roll cylindricity and the precision which are more accurate than those of the manual finishing are eliminated. A finished surface can be obtained and work efficiency is greatly improved. Further, when the roll rotation device is used, the worker only needs to monitor the device, and the load on the worker is greatly reduced.

(3) The polishing force can be adjusted by changing the fulcrum position or changing the balance weight,
Even if the state of the finished surface, the material of the roll, the material of the grindstone, or the like changes, the polishing can always be performed with the optimum polishing force, and a more accurate roll cylindricity or finished surface can be obtained. In addition, even if there are projections or the like on the polishing surface during polishing, the grindstone can be raised around the fulcrum and escape, so that there is an advantage that a grindstone breakage accident due to overload can be prevented.

(4) When the polishing surface is wider than the width of the grindstone, the horizontal feed mechanism allows the grinder base to be stably fed manually or automatically in the roll axis direction. Together with this, more accurate roll cylindricity and finished surface can be obtained, and work efficiency is also improved.

(5) The entire device can be made a relatively simple and compact device.

(6) Unmanned operation is possible only by installing the device body.
