Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for rolling a strip across its width by moving vertical rolls in the width direction of the strip.

In conventional edgers developed for this type of rolling, a number of rolling screws (4 screws) corresponding to the number of upper and lower shaft boxes of the vertical roll are assembled into the housing, and the shaft boxes are pushed and rolled by each screw. There is. In this way, conventionally, the axle box was pushed down using a screw built into the housing.
Since the housing is designed to receive all the reaction force during pushing, the housing must have a certain strength or more, and since a large number of screws are used, the structure is complicated due to the large number of parts.

The present invention has been made to solve the problems of the prior art and to provide an edger that is simple in structure and does not require a housing.

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

1 to 3 show an embodiment of the present invention, in which support members 1a and 1b are provided with a required interval in the horizontal direction, and the support members 1a and 1b are connected by a separator 2. It is supported by a pin joint 3a on one support member 1a and is supported by a pin joint 3b between upper and lower shaft boxes 4a and 5a, which are horizontally swingable about the pin joint 3a, and by a pin joint 3b on the other support member 1b. Vertical rolls 6a and 6b are arranged between upper and lower axle boxes 4b and 5b, respectively, which are horizontally swingable about the pin joint 3b, and the upper and lower axle boxes are assembled with bearings at both upper and lower ends of each vertical roll 6a, 6b. 4a, 5a, 4b, and 5b, and the rod tip of the upper stepping cylinder 8 is attached to the end opposite to the pin joint of the upper shaft box 4a on the left side in the strip entry direction 7, and the upper shaft box on the right side in the strip entry direction 7. The main body of the upper stepping cylinder 8 is pivotally attached to the opposite end of the pin joint of the lower shaft box 5a on the left, and the rod tip of the lower stepping cylinder 9 is similarly attached to the end of the left lower shaft box 5a on the opposite side to the pin joint. The bodies of the lower stepping cylinders 9 are pivotally connected to the ends of the axle box 5b on the side opposite to the pin joint, and both stepping cylinders 8, 9 are operated simultaneously to move the axle boxes 4a, 4b and 5a, 5b in opposite directions. Rotate each axle box 4a, 4b, 5a, 5
b is pushed in the width direction of the strip 10 so that the vertical rolls 6a, 6b roll the strip 10 in width. A gear box 15 installed on the floor, equipped with rollers 12 that roll on the rails 11b, and incorporating a pair of bevel gears 13 and 14.
b is disposed between the lower axle box 5b on the right side and the traveling rail 11b, and a gearbox 15a having a similar configuration.
is arranged between the lower axle box 5a and the traveling rail 11a,
Output shafts 16a, 16b connected to one bevel gear in each gearbox 15a, 15b are connected to the vertical rolls 6a, 6b, and input shafts 17a, 17b connected to the other bevel gear are provided with telescopic and bendable shafts. Reducer 19a, 1 via flexible joints 18a, 18b
9b, and motors 21a, 21 are connected to both reducers 19a, 19b via couplings 20a, 20b.
b is connected to the axle box, and the gearbox 15a,
15b moves accordingly, so that the rotational force of the motors 21a, 21b can be transmitted to the vertical rolls 6a, 6b.

In such a configuration, when rolling the strip in width, the motors 21a and 21b are driven to rotate the vertical rolls 6a and 6b, and the upper and lower stepping cylinders 8 and 9 are expanded and contracted as appropriate according to the amount of rolling. Left and right upper shaft boxes 4a, 4b and lower shaft boxes 5a, 5
The vertical rolls 6a, 6 are rotated in opposite directions around the pin joints 3a, 3b.
Adjust the interval b and roll the strip 10 onto the vertical roll 6.
Pass it between a and 6b.

During rolling, the upper stepping cylinder 8 is connected to the upper shaft box 4.
a, 4b, and the lower stepping cylinder 9 pulls the lower axle boxes 5a, 5b, respectively, keeping the distance between the vertical rolls 6a, 6b constant and rolling down the strip 10 by a predetermined amount.

FIG. 4 shows another embodiment, in which a spur gear 23 and a bevel gear 24 are fixed to a pivot 22 that is coaxial with the pin joint that is the center of swing of the vertical roll shaft box, and the spur gear meshes with the spur gear 23. 25 is connected to the lower end of the vertical roll shaft, and the shaft of the bevel gear 26 that meshes with the bevel gear 24 is connected to the reducer 1 through a coupling.
Connected to 9b. The configuration other than this is the same as that shown in FIGS. 1 to 3, and the same reference numerals represent the same parts.

When carried out in this way, one spur gear 25 moves along the peripheral edge of the other spur gear 23 as the axle box swings, and the meshing of both spur gears 23 and 25 is maintained, so that the flexible joint 18a , 18b, the power of the motors 21a, 21b is transferred to the vertical rolls 6a, 6.
b and can be rotated.

Fig. 5 shows a modification of the embodiment shown in Fig. 4, in which a roll unit support lever 2 is rotatably provided on the floor.
7 is connected to the vertical roll shaft, and a drive unit having the same structure as in FIG. 4 is provided on the upper part of the vertical roll, and the same reference numerals as in FIG. 4 represent the same parts.

Even with this configuration, the same effects as in FIG. 4 can be achieved.

Note that the present invention is not limited to the above-mentioned embodiments, and a screw or a normal cylinder device may be used in place of the stepping cylinder as a tensioning device that applies a pulling force to the vertical roll axle boxes together. Of course, various changes can be made without departing from the gist of the invention.

As described above, the present invention has a structure in which the axle boxes are pulled together by a tensioning device to maintain a constant vertical roll interval and are rolled down. In other words, the housing does not receive the reaction force when the axle box is pushed in. Therefore, the housing can be made unnecessary, the number of parts can be reduced, and the structure can be simplified, which are excellent effects.
