摘要： PURPOSE:To reduce the deflection of a arbor shaft in cutting time and to improve the stability of a cutting work by arranging an annular additional holder which is firmly held with the arbor shaft being spread by the internal pressure on two parallel arbor shafts. CONSTITUTION:On an arbor shaft 1A plural annular knives 5A are fitted and similarly plural annular additional holders 6A, 7A are fitted at the center part in the axial direction on the shaft 1A. The annular knife 5A and additional holders 6A, 7A are fitted from the shaft end of the arbor shaft 1A under the state of the arbor shaft 1A coming out of a stand 3 without receiving the internal pressure in a gap 4A and are slided to the specific position. Thereafter, the arbor shaft 1A is spread by receiving the internal pressure, and the annular knife 5A and additional holders 6A, 7A are firmly held on the arbor shaft 1A. On a arbor shaft 1B also an annular knife 5B, additional holders 6B, 7B are firmly held similar to the above. Consequently the arbor shafts 1A, 1B are reinforced at their bending rigidity and the deflection at working time is reduced.

摘要： PURPOSE:To facilitate the mounting of a knife by lightly holding the circular knife positioned on one side of a shaft at a low pressure, so as to be used as a reference for the positioning of another circular knife on the other side of the shaft, at a low pressure, and by holding the circular knives on both sides of the shaft at a high pressure. CONSTITUTION:Circular knives are inserted externally, while valves 31, 32 are closed and inner pressure is not applied to arbor shafts 10, 20. The circular knife of the upper arbor shaft 10 is slid in a shaft direction, and is positioned as predetermined, while the valve 31 is opened, and a low pressure is applied to the outer tube shaft of the upper arbor shaft 10 by a low pressure liquid pressure circuit 33, so as to hold the circular knife. The circular knife on the lower arbor shaft 20 is positioned on the lower arbor shaft 20, by adjusting a gap by using the circular knife on the upper arbor shaft 10 as a reference, while the valve 32 is opened, and the circular knife on the lower arbor shaft 20 is held at a predetermined position. A valve 34 is then opened, and a high pressure is applied to both of the arbor shafts 10, 20 by a high oil pressure circuit 35, so as to sufficiently widen the diameter of the outer tube shaft, whereby the circular knives can be held tight even at the time of slit work.

摘要： PURPOSE:To decrease the number of movement of a suspended crane and to reduce the area of floor for storage by providing hook receivers on the top of a stand and transporting and storing plural rolls by loading in parallel. CONSTITUTION:A transporter for rolling roll with which a single or plural rolls are transported and stored consists of the followings: a stand 6 where top beams 6b supported with plural legs 6a are so oppositely provided with a distance that the body of the rolling roll 1 can be inserted, are fixed with spacers 6c and the plural rolling rolls 1 can be stored in stack of laying insteps, tapered supports 11 of wood or hard rubber, etc., with which bearing parts 1a of the rolling rolls 1 are supported on the top of the beams 6b of the top of the stand, and sockets 6a, with which the hook of the suspended crane is received, provided on both end parts of the beams 6b of the top of the stand. Accordingly, because plural rolls are transported at a time, the number of movement of the suspended crane is remarkably decreased. And, because the storage in stack can be done, the area of floor for storage is reduced too.

摘要： PURPOSE:To form a good coiling shape all the time by providing a hydraulic cylinder on a pinching roll and by performing at least more than one of each function of the adjustment in the rolling reduction force, position adjustment and meandering correction, in a strip winding coiler. CONSTITUTION:A hydraulic cylinder 8 is provided on pinching rolls 6, 7 in the device made to wind a strip with its feeding in a mandrel part via the upper and lower pinching rolls 6, 7. A proportional type solenoid pressure reducing valve 14 is provided on the hydraulic cylinder 6 via a servo-valve 13, linked to a pressure oil source 15 to perform the position control by a position detector 17.

摘要： PURPOSE:To permit easy and quick exchange of rolling rolls by constituting a control member for controlling camber in such a manner that the member can move between a control position and retreat position. CONSTITUTION:A piston of a cylinder 25 is advanced to install a wiper 22 and a roll cooling header 21 at a prescribed position. A lining 33 having a suitable thickness is fitted to a stopper 32 so that the spacing between the end of a camber control plate and the rolling rolls 12 attains a prescribed length. A piston of a cylinder 17 is then advanced to move the plate 11 until the lining 33 contacts a housing 31. After the plate 11 is installed at the prescribed position, the rolls 12 are rotationally driven then a rolling stock is supplies and rolling is started. The rolled material 13 emitted from the rolls 12 is fed in an arrow 36 direction. The camber of the material 13 is controlled as the material 13 is pressed to the plate 11.
