PURPOSE:To prevent the adverse influence of high temp. heating of dies upon respective parts by projecting the working parts of the dies into the air to increase the distances from packers and other driving power transmitting means to the working parts and providing shielding means for transfer heat between the dies and the packers. CONSTITUTION:A motor is driven and a work 36 is heated and is fed into dies 16, 16a, 16b like an arrow 37 to heat the working ends of the dies to about 800 deg.C. Spindles 11, 11a, 11b are rotated in an arrow 38 direction by means of a pulley, a belt 35 and a pulley 8. As the spindles rotate, packers 13, 13a, 13b are forced out in the central direction, by which the dies 16, 16a, 16b are also forced in the same direction and the work 36 is worked to a prescribed outside shape. In this stage, the dies and the packers are in contact with each other through balls 18, 22 and liners 12; therefore, the high temp. heating of the dies does not give any adverse influence upon the respective parts. |
