Description of the Invention (1) [Technical Field to which the Invention belongs] The present invention relates to a reversible non-guided rolling device. While the material to be rolled is moved back and forth along the rolling line, the material is rolled into a reversible non-guided rolling device having a desired cross-sectional shape. [Description of Related Technology] There is known a reverse rolling device for rolling a long rolled material such as a bar steel or a wire into a predetermined cross-sectional shape. This reverse rolling device is structured as follows: two rolling mills are arranged in series along the rolling line of the material being rolled, one pair of rolling mills is equipped with a pair of rotatable horizontal rolling wheels, and the other One rolling mill is equipped with a pair of rotatable vertical rolling rollers. In addition, on one and the other rolling rollers, a plurality of roller hole-type apertures (cariba) corresponding to a required rolling schedule are formed at predetermined intervals in the axial direction. The rollers are moved in a direction crossing the rolling line of the material to be rolled, so that the rolling hole pattern of each rolling roller can be consistent with the rolling line. Furthermore, the aforementioned reverse rolling device rolls the material to be rolled continuously through predetermined roll holes on the rolling rolls provided on the two rolling mills, and then rolls the rolling rolls separately. Move to the position where the next roller pass pattern that the material should pass is consistent with the rolling line, and then make the material to be rolled continuously from the opposite direction through the roller pass pattern to sequentially roll. That is, the reverse rolling device can be rolled into a predetermined cross-sectional shape as long as the rolled material is moved back along a certain rolling line. The roller hole pattern formed on the aforementioned rolling wheel is alternately formed with an oval hole pattern and a circular hole pattern in the axial direction.

Description of the invention (2) The i H-rolled & oval-shaped rolled material will pass through the circular hole shape of another square-rolling machine and then rolled into The cross section has a circular shape. In addition, in order to guide the rolled material to be rolled with the oval-shaped hole shape to the circular hole shape with a correct posture, a holding guide for the rolled material, such as a roller, is provided between the two rolling mills. . Furthermore, in order to change the cross-sectional size of the material to be rolled, a pressing device for adjusting the gap between the rolling rollers facing each other must be provided in each of the aforementioned tumble dryers. The structure of this friction device is relative to one of the rolling rollers' which is arranged at a fixed position so that the other rolling roller can be moved close to or separated from it. That is, the housing is provided with a support that can be moved freely, and the support has a free-rolling roller, and the 5¾ support is moved by an appropriate driving mechanism to adjust the roller clearance. In the case where the holding guide attached to the aforementioned reverse rolling device is used to adjust the clearance of the rolling rollers by the rolling device provided in the rolling mill, it must be adjusted to an appropriate position in accordance with this action, so there are instructions to change, etc. The disadvantage is that the time required for adjustment becomes longer. In addition, the poor guidance of the guide is closely related to the poor quality of the rolled product. Therefore, it is necessary to carry out frequent bearing maintenance, inspection of the surface defects of the rollers, and inspection of the rotation status. In addition, since a holding guide is provided between the rolling mills, the overall length of the device becomes long and the structure becomes complicated. Therefore, there is a problem that the cost of equipment is increased. As mentioned above, the roller hole pattern formed on the rolling roller is an elliptical, shaped or diamond_angled hole pattern set according to a preset rolling procedure, so it is rolled by the same rolling roller. The size range of the rolled material is small. Therefore, in order to roll the rolled paper in a wide range of sizes, the Chinese National Standard (CNS) A4 specification was applied (210 x 297 public copy --- I -------------- ( Please read the notes on the back before filling this page) Order -------- 520304 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 312500 A7 B7 V.
