Title: Rolling mill
Inventor: KUMABE SATORU
IPC: B21B13/14
Filed: 1980-09-17
Abstract: PURPOSE:To make a roll bending device capable of working in a decrease bending work without  installing any additional hydraulic cylinder, by making an end of a rod fully inserted into a  vertical hole of an intermediate roll chock contact with a bending device attached to a backup roll  chock, and another end contact with a work roll chock. CONSTITUTION:A vertical through hole 11 is bored in a chock 10 of an intermediate roll 3 arranged between an upper work roll 1 and an upper backup roll 2, at a position coincident on a  plane with the position of a hydraulic cylinder 7 set in a chock 8 of the roll 2 when a rod 12 is inserted into this hole 11. A rod 12 of a prescribed length is fully inserted into this hole 11; the top  end of a spring 14, set in a side chamber 13 formed in the hole 11, is connected with a bracket 15  attached to the upper part of the rod 12; hereby, the rod 12 is upheld at a prescribed vertical position against the chock 10 so as not to drop off of the chock 10. When controlling the decrease  bending work, each hydraulic cylinder 4 set in each block 5 is placed under a constricted condition, and upper and lower hydraulic cylinders 7 are placed under an extended condition; the decrease bending work is controlled under these conditions. Hereupon, the bending load of the  upper hydraulic cylinder 7 is impressed upon a roll chock 6 and the roll chock 10 is perfectly free  from the bending load. As a result, the intermediate roll 3 is free from the influence of the bending force, and the upper work roll 1 fully receives the essential bending effect.

Filed: 1988-05-27
Abstract: PURPOSE:To prevent the plastic deformation of a magnetic disk in a waiting state from being generated by forming a magnetic head so as to be movable to a waiting position outside than the outermost peripheral track position of the magnetic disk, and forming the contact plane of a pad to a position not exceeding the waiting position toward the outside in a radius direction. CONSTITUTION:The magnetic head 32 is formed so as to be movable to the waiting position P3 outside than the outermost peripheral track P1 of the magnetic disk 20, and the magnetic head 32 is moved to the waiting position P3 outside in a waiting state where no read/write is performed. Also, the contact plane 12 of the pad 10 being brought into contact with the magnetic disk 20 from a side opposite to the magnetic head 32 is formed to the position exceeding the outermost peripheral track P1 but not exceeding the waiting position P3 outside the radius direction. In such a way, since no contact plane to restrict the magnetic disk 20 exists in the periphery of the waiting position even when the magnetic head 32 exists at the waiting position P3, the deformation of the magnetic disk can be moderated, and it is not feared to generate the plastic deformation of the magnetic disk.
