摘要： PURPOSE:To execute a stop control of a work roll under a reverse nongenerated state by detecting a real rotational direction on the way of a stop of the work roll, grasping a reverse generated state, and controlling it in the direction for eliminating a twist of an elastic connecting system. CONSTITUTION:Detectors 31, 31' generate signal 36, 36' corresponding to each detecting body 32, 32' when a coupling 22 rotates, and detect a real rotational direction of a work roll 20. The detected signals 36, 36' are inputted to an operational comparator 33, and outputted only while a rotational direction detecting signal 42 and an operating signal 40 are being inputted. When the signal from the comparator 33 is a forward turn, a stop control is executed as it is, and on the other hand, when the signal from the operational comparator 33 detects a reverse, a driving machine 26 is brought to a driving control in the forward turn direction. That is to say, by repeating a reverse preventing action of the work roll in this way, a control device 34 controls the driving machine 26 so that a reverse of the work roll 20 is not caused at the time of a stop of a mill, based on an input data from the operational comparator 33 and an input data from a pilot generator 35.

摘要： PURPOSE:To quickly rearranged the rolls without any hindrance, by making the operation side of a pressure block withdraw first and go down next by actions of a push-pull device and an elevator. CONSTITUTION:A lower backup roll 4 is elevated by a lifting cylinder 19 provided in a lower separator 18 of a housing 1 and a lifting V-saddle 17 connected with the cylinder 19. Hereby, pressure blocks 7, 13 become freely horizontally movable in the direction perendicular to the rolling line; on the driving side the block 13 is withdrawn by hydraulic cylinders 14, 15; on the operation side, the block 7 is withdrawn by hydraulic cylinders 8, 9. Further, the block 7 is brought down by a hydraulic cylinder 12 in order to prevent the interfaces between the bottom surface of the chock of the lower backup roll 4 and the upper surface of the block 7 during the horizontal movement of the lower backup roll 4. Accordingly, the rearrangment of the backup roll is quickly carried out without the hindrance of the block 7.

摘要： PROBLEM TO BE SOLVED: To provide a press capable of suppressing slider inclination due to sliding resistance and uneven load. SOLUTION: When a driving machine 9 is actuated to apply rotational force to the output shaft 9a, this force is transformed to a nearly vertical reciprocating motion from a crank mechanism 11 through a con'rod 16; a driving member 60 is thereby guided by a slider guide 4 through a bush 21 and moved downward, so that an upper die 22 fixed on the lower end of the driving member 60 forms a work arranged on a lower die 23 on the bolster 2 in accordance with the shape of the lower die 23. At this time, when the rotational force of the output shaft 9a is transmitted to the rotary shaft 30 of a knock-out device through a power transmission mechanism 95 to rotate the rotary shaft 30 and a cam 28 reaches a certain angle of rotation, a push-up pin 25 is pushed up to actuate a knock-out pin 36 upward and to extrude a forming member to the outside of the lower die 23.

摘要： PURPOSE:To realize miniaturization and a high wind quantity, by arranging respectively an inner and outer air changeover mechanism on the upper wall surface of a scroll casing and a centrifugal fan motor at the bottom wall surface, and forming an auxiliary inner air take-in opening at a motor-fitting surface. CONSTITUTION:The drive motor 9 of a centrifugal fan 10 is provided at the bottom wall surface 7b of a scroll casing 7 and at the same time, an auxiliary inner air take-in opening 12 is formed at the bottom wall surface 7b. As a result, when inner and outer air changeover doors 5, 6 are in an inner air suction state, the auxiliary inner air take-in opening 12 is opened through the linkage of the 2nd door 13 provided on the motor-fitting side of the casing 7 and the take-in of an auxiliary wind (inner air) is done. Accordingly, making up for the lowering of the quantity of air can be realized, and also, an suction wind quantity allotment per one opening on an air take-in side against the quantity of discharge wind can be lowered, and the resistance of suction is decreased, and the efficiency of suction is improved. Thus, miniaturization and a high wind quantity are realized.
