IPC: B21B17/02
Filed: 1994-12-01
Abstract: PURPOSE: To avoid the increase in the working degree in the two roll stand rows, and to reduce the bar changing work and the cost by changing the wall thickness as large as the wall thickness change of a finished tube on the stock tube side to be fed in two roll stand rows. CONSTITUTION: A pair of grooved rolls 11 whose screw-down direction is orthogonal to each other and four roll stands 10 whose screw-down direction Is deviated by 45 deg. are arranged, a stock tube 20 where a core rod 30 is inserted is fed to the stand rows, and the wall thickness is reduced by the two roll stand rows, and the wall thickness fluctuation in the circumferential direction is reduced by the four roll stands 10 respectively. When the finished tube of the different wall thickness is rolled by tightening the roll gap by the two roll stand rows using the core rod 30 of the same outer diameter, the wall thickness change as large as that of the wall thickness change of the finished tube is achieved on the side of the stock tube to be fed to suppress the increase in the working degree by the two roll stand rows.  The peak thickness nonuniformity at four positions of 45 deg. from the groove bottom which is generated in the two rolling operations is eliminated thereby, to reduce the bar changing work and the cost.

IPC: G01N33/20
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a device capable of measuring the amount of inclusions in a molten aluminum alloy with little dispersion and good operability in a short time. SOLUTION: An inclusion measuring device is formed of a measuring main body 10 and a detecting moans 20. The measuring main body 10 is formed of a tubular part 11 forming cylindrical space 13 and of a filter 15 placed to one end of the tubular part 11. The detecting means 20 detects the amount of molten aluminum which permeates through the filter 15 and is housed in the cylindrical space 13 of the tubular part 11.  One end of the tubular part 10 is immersed at a predetermined depth in a molten aluminum alloy, and the detecting means 20 detects the amount of the molten aluminum alloy which is passed through the filter 15 within a predetermined time by the head pressure of the molten aluminum alloy corresponding to the predetermined depth and is housed in the cylindrical space 13, and the rate of inclusions contained in the molten aluminum alloy is measured by the amount of the housed molten aluminum alloy. In the case that a large amount of inclusions is contained, the inclusions block the mesh of the filter 15 to increase the passage resistance of a molten aluminum alloy. The amount of a molten aluminum alloy to pass through the filter 15 is changed by the passage resistance to indicate the amount of inclusions.  It is possible to know the amount of inclusions immediately at a field by the detecting means 20.

Filed: 1990-11-30
Abstract: PURPOSE:To improve detecting precision of a contact point by a method wherein a relative position relation when a displacement amount after correction of displacement occurring when a tool is brought into contact with a work is decided as a contact point. CONSTITUTION:A tool 1 is displaced by exerting a machining reaction force generated when the tool l makes contact with a work 6 through a relatively low rigidity structure part formed to a part of a tool holding mechanism 3. The displacement is fetched in a non-contact manner as an electric signal. Through correction of the displacement by means of a displacement fluctuation produced when the work 6 is not in contact with the tool 1, a relative position relation between the tool 1 and the tool holding mechanism 3 is determined, and a point available when the relative position relation value exceeds a given value is decided as a contact point. Even when a change in size, an error in the shape of a tool, and the mounting errors of the tool 1 and the work 6 are produced owing to thermal expansion of the tool 1, the work 6, and a mechanism to hold the tool and the work, a relative distance between the tool 1 and the work 6 can be measured and high-precise machining can be made possible.
