摘要： PURPOSE:To automatically prevent and correct twists by detecting a axis deviation amount by a detector installed in front of a breakdown mill and moving a formed stock by a distance corresponding to the detected amount by use of a movable side guide. CONSTITUTION:For a tube manufacturing device consisting of zones such as a breakdown forming A, intermediate forming B, fin pass forming C, and squeeze forming D in a series, a axis deviation detector 7, movable side guide 6, and fixed side guide 5 are installed in front of the zone A. An axis deviation amount of a formed stock 4 is detected by the detector 7 and the measured result is inputted to the guide 6 to correct the deviation. Thus, the productivity of the tube manufacturing work is improved.

摘要： PURPOSE:To permit optional online setting of a roll width by fitting stationary rolls and moving rolls to both ends of an outside peripheral screw of a roll shaft and moving the moving rolls by a prescribed roll width adjusting screw and external gear. CONSTITUTION:The stationary horizontal roll 21b and the movable horizontal roll 21a are fitted onto the outside peripheral screw part 24b of the roll shaft 22 by which a lower horizontal roll 21 is formed. The roll width adjusting screw 24a screwed to the screw 24b is fitted to the inside end face of the roll 21a and the external gear 26 is meshed with the gear part 25 on the outside periphery thereof. The change of the roll width is executed by removing a prescribed stopper, meshing the gears 26, 25, rotating the gear and moving the roll 21a to change the spacing according to the above-mentioned constitution. The upper horizontal roll 20 is similarly constituted. The optional online setting of the roll width is thus made possible.

摘要： PURPOSE:To obtain a rolling mill, compact and excellent in production efficiency, by forming one piece and two pieces of work rolls into a triangular shape and installing respective backup rolls nearly on the extensions of two imaginary lines formed by connecting the axial center of the former to those of the latter two rolls respectively. CONSTITUTION:Backup rolls 4, 5 are arranged respectively on the extensions of the lines formed by connecting the center of a work roll 1 to the centers of the 1st and 2nd lower work rolls 2, 3 respectively. A rolling material advanced from the left side is subjected to the rolling reduction of the 1st time at a biting point A of the rolls 1, 2, and is successively subjected to the rolling reduction of the 2nd time at a biting point B of the rolls 1, 3. In this case, because the roll gaps at the points A, B can be independently adjusted in the 1st and 2nd rolling-reduction systems constituted of the rolls 1, 2, 4 and 1, 3, 5 respectively, a prescribed sheet thickness is obtained. Further, because the roll 1 is supported by two pieces of the large diameter-rolls 4, 5, the roll 1 is made small in diameter as compared with the rolls 2, 3, and moreover a different peripheral-speeds rolling can be performed by setting the speeds of respective rolls 1, 2, 3 to V3>V1>V2.
摘要翻译：目的：通过将一片和两片工作辊成形为三角形，并将各个支承辊几乎安装在通过连接轴承中心形成的两条假想线的延伸部上，以获得一个紧凑的生产效率的轧机，前者分别为后两卷。构成：备用辊4,5分别布置在通过将工作辊1的中心连接到第一和第二下部工作辊2,3的中心而形成的线的延伸部上。从左侧推进的轧制材料在轧辊1,2的咬入点A处经历第一次的轧制压下，并且在辊的咬点B处依次进行第二次的轧制压下在这种情况下，由于可以分别在由辊1,2,4和1,3构成的第一和第二滚动压缩系统中独立地调节点A，B处的辊间隙，得到片材厚度。此外，由于辊1由两个大直径辊4,5支撑，因此与辊2,3相比辊1的直径小，此外，可以通过以下方式进行不同的圆周速度轧制：将各辊1，2 3的速度设定为V3> V1> V2。

摘要： PURPOSE:To freely and distinctively manufacture many size of the shaped products with economy, effect and well dimension accuracy by making the stand interval changable corresponding to the interval of the roll on the roll stands in cantilever arranged in opposite positions with interposing the pass-line of the material to be shaped. CONSTITUTION:A pair of overhang roll stands 1A, 1B providing the roll 20A-20D are set in mutually opposite, a pair of the upper side stand interval adjusting devices 11A, 11B are set at its upper side and the lower side stand interval adjusting device 6 is set at the lower side. Therefore, the interval of stands is changed corresponding to the interval of rolls. Further, by reciprocating the shift frame 3A, 3B with the shift cylinder 4A on the sole plate 2, the above roll stands 1A, 1B are shifted to the position without interfering with the material to be rolled except the passing time of the required material to be rolled.
