Title: Transporting apparatus for high-temperature metallic billet
Inventor: TACHIBANA SEISHIROU
IPC: B21B39/00
Filed: 1980-06-04
Abstract: PURPOSE:To transport a steel billet to a rolling plant while preventing the billet from cooling, by employing a container car provided with a billet container lined with a heat insulating material for transporting a high-temperature steel billet to a rolling plant. CONSTITUTION:A continuously cast ingot is split into billets which are then transported to a next hot rolling plant while keeping the billet at high temperatures by preventing the billet from being firecely cooled on the way of transportation; hereby, the energy consumption for heating the billet to be fed to a hot rolling line is reduced. For this purpose, plural billet loading rollers 7 are installed on a truck 2 tavellable with its wheels 3; the upper space of the loading rollers 7 is covered with an enclosing wall 10 internally lined with a heat insulating material such as an asbestos plate, and a front door and a rear door are provided in the enclosing wall 10. A high-temperature billet W, being taken out of a continuous casting machine and split into a suitable length, is put in a billet container 15 by the rotation of the loading rollers 7 through the front door of the enclosing wall 10, and is transported under this condition; the billet W is then taken out of the rear door and is fed to a rolling line. Since the billet is hardly cooled on the way of transportation, the heat energy for reheating the billet before the hot rolling work is saved.

Filed: 1994-04-14
Abstract: PURPOSE:To prevent the occurrence of galling between a guide and a screw shaft by a method wherein guides made of a rigid material arranged at the two end parts of a nut are brought into an eccentric state in an opposite azimuth from the screw shaft. CONSTITUTION:In a nut movement type jack, when a motor 7 is energized and a screw shaft 1 is rotated through a worm reduction gear 6, a nut housing 5 and a cylinder body 8 are moved forward through a nut 4 and a driven body 11 is pushed in a direction in which the driven body is separated away from a fixed body 10. In this case, the axial lateral load of a bending moment is carried by guides 2 and 3 made of a rigid material at the two end parts of the nut 4. The so formed guides 2 and 3 are arranged eccetrically by (a guide inside diameter - a screw shaft outside diameter)/2 in an azimuth in which the centers of the inside diameters thereof are positioned opposite to each other in a 180 deg. arc. This constitution causes the occurrence of surface contact in a place in which the azimuths are different by 180 deg. and reduces the surface pressure of the contact surface of the guide part.

Title: Method for bending channel steel
Inventor: UTSUNOMIYA HANJI
IPC: B21D7/06
Filed: 1993-03-10
Abstract: PURPOSE:To easily bend a channel steel without providing a notch on a side by bending a hole part of a flange while orthogonally pressing the part from outside to inside with plate like thrust dies, and thereafter bending the part until matching the oblique surfaces of respective dies. CONSTITUTION:Holes 6 are opened on flanges of both sides so that the parts adjoining to an internal surface of a web 5 are made symmetrical. Outer dies 8 of both sides are pressed on a channel steel 1, after the flange 3 is clamped together with an internal die 7, the channel steel is bent while turning both thrust dies 10 to the direction of the channel steel 1. The thrust die 10 and the internal die 7 are a relation of a punch and a die, and because the width of the internal die 7 is made larger toward the end part of the flange 3, the flange 3 is bent to the inner side from the end part when the thrust die 10 is turned. Because the bending is stopped when the oblique surfaces 9 of respective dies are matched, so the bending angle of the channel steel 1 is set by the angle of the oblique surface 9.
