IPC: B66C1/28
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an ingot chucking method capable of chucking an ingot without fail and a device thereof. SOLUTION: A pair of holding claws 16A and 16B are moved in a direction of making them come nearer to each other from the specified reference position, and when either of these holding claws 16A and 16B abuts upon the end face of an ingot (In), its movement is stopped. Next, each travel S of the paired holding claws 16A and 16B from the reference position is detected, and the detected travel S is substituted to a expression of x=(T-D-2S)/2, T: space between holding members situated in the reference position, D: length of ingot)and thereby (x) is calculated. Then, a chuck unit 5 is horizontally moved as far as a portion of this (x).  With this, since both centers of the ingot In and the chuck unit 5 are accorded with each other, if subsequently both these holding claws 16A and 16B are moved as far as this (x) in a direction of making them come nearer to each other, the ingot In is held in a state that its center is accorded with that of the chuck unit 5.

Abstract: PURPOSE:To facilitate machining with securing clearance precision, etc., by forming at least one fitting part of subzero cooling hardener between both of male-female fitting members and treating the fitting part by means of subzero cooling after carrying out clearance adjustment machining in the fixing part under the ordinary temperature. CONSTITUTION:At least a fitting part 4a of one member 4 to the other member between two members, which male-female fits each other, is formed of a subzero cooling hardener A which is hardened by subzero cooling. While the fitting part 4a is roughly machined, one member 4 is fitted to the other member to carry out clearance adjustment machining. Then, a coolant such as snow dry ice, etc., is heaped up on the fitting part 4a so that the fitting part 4a is treated by subzero cooling. In this way, clearance adjustment machining in the fitting part 4a can be carried out easily as the hardness of the subzero hardener A is low before subzero cooling. On the other hand, the hardness of the fitting part 4a is increased by subzero cooling without any distortion and abrasion resistance and clearance precision are secured.

Filed: 1999-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a stationary blade of an axial compressor capable of suppressing, to a minimum, a wave drag due to an impact wave produced in a transonic range. SOLUTION: This stationary blade of an axial compressor comprises a front surface producing a positive pressure and a rear surface producing a negative pressure, and the front and rear surfaces are present on one side of a chord line.
