摘要： PURPOSE: To improve shifting control performance and shifted position holding performance by a structure wherein intermediate cylinders are arranged in the hydraulic cylinder circuit for driving working equipment or the like and holding it in the shifted position in order to employ high viscous working fluid as working oil in hydraulic cylinder side.
CONSTITUTION: In case of rolling mill having a pair of upper and lower rolls 109 and 110, the intermediate cylinders 101 are separately interposed in pipings between control valves 104 and both right and left chambers of the hydraulic cylinders 103, which shift the respective rolls 109 and 110 axially and hold them in the shifted positions. And yet, the fluid such as grease or the like, the viscosity of which is higher than that of the working oil in hydraulic pump 105 side, is employed as the working oil in the pipings between the hydraulic cylinders 103 and the intermediate cylinders 101. Furthermore, pilot check valves 102 are arranged at the entry ports in the head side and rod side of the hydraulic cylinders 103 respectively. The respective control valves 104 are controlled by a control device 113 based upon the deviation between the outputs of position sensors 108 and set signals 112.

摘要： PURPOSE:To facilitate resetting work of rollers by installing a work roll shift mechanism and transferring upper and lower work rolls to a limit of stroke, and then performing resetting and zero-adjusting work. CONSTITUTION:Upper and lower roll chocks 2a, 2a' are arranged freely movably in vertical and horizontal directions on an internal window of work side housing 1a. Shafts of work rolls 3a, 3b are supported within the chocks 2a, 2a'. A bracket 5 is fixed to the housing 1a by bolts, and a cylinder 8 is arranged on the upper end face of the bracket 5 at a right angle to the rolling line. When the cylinder 8 is moved to Z direction, a lever 12 rotates with a center axis 11 as a fulcrum and move rolls 3a, 3b in the shaft direction X. In the case of resetting rolls, by transferring the rolls 3a, 3b to the limiting positions of strokes, the resetting and zero-adjusting works may be performed simply. Thus, the resetting work is simplified.

摘要： PURPOSE:To prevent lowering of grindability and generation of finishing unevenness by starting grinding after a shape of a grinding face of a grinding body is formed into a stable grinding face in accordance with a rolling roll diameter, an eccecntric amount and tilted face, etc. CONSTITUTION:In the case of using new cup-shaped grinding stones 3 as a grinding body for on-line grinding of a rolling roll 2, the grinding face of the stone 3 is previously formed into a stable grinding face 3a having a profile (m2) and then grinding is started. The profile (m2) is set in accordance with a rolling roll diameter D, an eccentric amount H of the rotation axis line Og of the stone 3 to the rotation axial center Or, and a slant angle alpha of the rotation axis line Og to the orthogonal plane to the rotation axis of the roll 2. Hence, the roll 2 is ground into a highly accurate roll profile with stable grinding capability and grinding ratio at all times. Changing frequencies of the stones 3 are reduced because of use of hard type grinding stones 3.

摘要： PURPOSE:To improve maneuverability and maintainability of rolling mill by supplying a low pressure oil when a rolling work is performed, and a high pressure oil when resetting of rollers is performed respectively to a hydraulic cylinder of a press shift from one to another. CONSTITUTION:A work roll 4 is connected to a shift cylinder 8 via. a chock 5, a latch 6 and a shift frame 7 enabling the axial movement free. An outer cylinder of a main body 2 of a spindle is connected to a press cylinder 10 via a thrust bearing 9. A hydraulic line of the device 4 is maintained normally at a pressure of 210kg/cm and a feeding hydraulic pressure is reduced to 70kg/cm via a flow rate control valve and a pressure setting device to supply hydraulic pressure for the press cylinder 10 for rolling. In this instance, a proper amount of press power is provided, and an extraordinary wear of the roll 4, a coupling 3 etc. is prevented. For the roll resetting, the high pressure oil is used as it is and the escape of the spindle is prevented. By means of this method, the maneuverability and maintenability is improved.

摘要： PURPOSE:The titled device with simple controlling system for completely stopping one of two trucks when another truck is moving, by constituting so as to disengage one of two lock pins when another lock pin is engaged; hereupon, one lock pin is for the traveling truck which is engageable with the engaging part of the traveling rail, and another lock pin is for the traveling truck that is engageable with the engaging part of the traversing truck. CONSTITUTION:When the lock pin 8 for the traveling truck faces against the engaging hole installed in the traveling rail 1, the lock-pin-elevating-cylinder installed on the lower frame 3C of the traveling truck actuates, and its power is transmitted to the racks 15 and 16 through the arm 21, rotary shaft 13, and pinions 17, 18; and then, the lock pins 8 and 10 go down. Hereby, the lock pin 8 engages with the engaging hole, the traveling truck is locked, the lock pin 10 is disengaged from the engaging hole 23, and the traversing truck 5 becomes possible to move transversely. When the truck 5 comes to the end of traverse motion, and the lock pin 10 faces against the engaging hole 23, the lock-pin-elevating-cylinder actuates in the opposite direction against the former action, and locks the truck 5 and makes travelable the traveling truck.

摘要： PURPOSE:To hold at a target roll profile where the shape of a product plate is made optimum by providing a roll profile arithmetic controller, determining the optimum pressing position of a grinding wheel and changing a grinding position. CONSTITUTION:The roll profile arithmetic controller 29 is provided in a on-line roll grinder device. The roll profile to be ground, which is a difference between a roll profile actually measured with a detector 11 and the target roll profile which is arithmetically processed to become the optimum roll profile, is divided for each oscilater of the grinding wheel 10; an intersected point with a grinding profile is determined and a grinding section is decided. The mid point between the intersected point and the maximum wear point in an ungrinding section is made a position to start or finish the grinding; an optimum position to press the grinding wheel is determined for each oscilater; and also the grinding position is changed. Thus, the difference between the roll profile after grinding and the target profile is reduced.
