Title: Method and device for reduction of metal tube
Inventor: TANAKA NOBUKI
IPC: B21B31/02
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the roll setting-up frequency of reduction equipment by making it possible to rotate the housing of an idle roll stand around a tube axis center, and rotating the housing in the direction reducing the squarishness of the tube to be rolled at any time during the continuous reduction. SOLUTION: Since all roll is made an idle roll 1 which is not connected to a drive motor, it is easy to rotate the housing 2 during the reduction. By arranging a device like this as some of roll stands, the housing 2 is rotated in the direction reducing the squarishness of the tube any time during the continuous reduction. The squarishness is conformed by cutting periodically a part of the tube and by observing its inside surface. When a squarishness ratio becomes a tendency to increase, by rotating online the housing 2 of the idle roll stand, a phase angle pattern at that time is changed so that it is brought near a proper phase pattern corresponding to a roll wear state.

Filed: 1995-04-17
Abstract: PURPOSE: To specify a wheel in which the internal pressure of a tire is lowered by comparing and judging the internal pressure of a tire of each wheel from the rotation angular speed of each wheel. CONSTITUTION: When the tire internal pressure of a front left wheel is lowered, the rotation angular speed VWFL is increased, and the front wheel speed right to left ratio PF is increased more than a reference point CA, the wheel load of a rear right wheel is decreased to decrease the rear right wheel speed VWRR, and the wheel load of a rear left wheel is increased to increase the rear left wheel speed VWRL. Accordingly, the rear wheel speed left to right ratio PF is a little increased.  On the other hand, when the tire internal pressure of a front right wheel is lowered, and the front wheel speed left to right ratio PF is decreased below a reference point CA, the rear wheel speed left to right ratio PR is a little decreased, and the front and rear wheel speed left to right ratios PF, PR generated in two situations draw a locus of a straight line L1 A passing a fixed reference point CA according to the tire internal pressure lowering rate of each wheel. Similarly, when the rear wheel internal pressure is lowered, a locus of a straight line L2 A is drawn. It is judged whether coordinates PF, PR are included or not in an area A formed by a sum-set of areas where a very small width dA is given to the straight lines L1 A, L2 A formed by the front and rear wheel speed left to right ratios.
