る。2. Description of the Related Art A plurality of rolling mills are arranged in series along a pass line of a material to be rolled such as a steel bar or a wire rod, and the material to be rolled is rolled to required dimensions by passing the material to be rolled through these rolling mills. Equipment is known. Each rolling mill is provided with a pair of rolling rolls rotatably in a housing, and performs required rolling by passing a material to be rolled through a roll hole die (calibre) formed between the two rolls. In the elongation rolling of the material to be rolled in the rolling equipment, the oval hole type and the round hole type are sequentially and alternately arranged as the roll hole type, and the diamond hole type and the square hole type are alternately arranged as the roll hole type. The diamond-square method is appropriately used. In the final rolling performed in the final stage of rolling, oval
In the round method, a round hole shape as close to a perfect circle as possible is used.

I do it. Also, in the case of the rhombus-square method, a similar holding guide for the material to be rolled is installed on the entrance side of the square hole type in order to secure a high surface reduction rate.

This rolling-down device is configured to move the other rolling roll close to and away from one rolling roll disposed at a fixed position.
That is, a stand having one rolling roll rotatably provided in the housing is movably disposed, and the stand is moved by an appropriate drive means to adjust the roll gap.

る難点もあった。When the gap between the rolling rolls is adjusted by a reduction device provided in the rolling mill, the holding guide attached to the rolling mill is moved to an appropriate position. Adjustment is required, and there is a disadvantage that the time required for the adjustment accompanying an order change or the like becomes long. In addition, since a defective guide of the holding guide leads to a defective rolled product, maintenance of the bearing, inspection of surface defects of the roller, inspection of the rotation state, and the like have to be frequently performed. In addition, it is pointed out that a holding guide is provided between the rolling mills, which complicates the structure and increases facility costs. Further, since it is necessary to secure a space for installing the holding guide, there is a problem that the total length of the equipment is increased and the installation space in the factory is increased.

Although the configuration driven by the base drive motor has been described,
Four rolling roll pairs can be driven by one drive motor. That is, two units including the first rolling rolls 12 and 12 and the second rolling rolls 14 and 14 are arranged in series along the pass line PL, and the reduction gears disposed on the drive shafts 20 and 20 of each unit. The four rolling rolls are rotated by one motor 18 by composing the gears 24 and 24 so as to commonly mesh with the gear 26 disposed on the drive motor 18. In addition, a pair of first driven gears 4
0, 40 and one of the pair of second driven gears 54, 54 are omitted, and the first intermediate gear 36 and one of the first driven gears 40 mesh with the gears 44, 44, and the second The gear 5 is connected to the intermediate gear 50 and one second driven gear 54.
It is also possible to engage 8,58.

の精密圧延を行ない得る利点がある。As described above, according to the rolling mill of the present invention, the power is branched off from the drive shaft rotated by the drive motor to rotate the first rolling roll and the second rolling roll. Therefore, the distance between the shaft centers of the two rolls can be set to be short, and the provision of a roller guide or the like as a material guiding unit is unnecessary, and the structure can be simplified, and
Costs can be kept low. In addition, there is an advantage that the occurrence of defective products caused by the guide means is eliminated, and a time-consuming adjustment work and a complicated inspection work accompanying the order change can be omitted. In addition, by shortening the interval between the adjacent rolling rolls, the length of the entire rolling equipment can be shortened, and the space in the factory can be effectively used. In addition, two drive motors
Since the rolling pair of rolls is rotated, there is an advantage that precision rolling of the material to be rolled can be performed without causing an impact drop between the two rolls.
