始される。Next, the operation of the above @ position will be explained. The billet 10 is installed in this apparatus by passing through the above-mentioned immersion chamber 1, the outer dynamic pressure tube '2, the inlet nozzle 3, the inner dynamic pressure tube 7 and the outer dynamic pressure tube 8. The billet 10 that has passed through the outlet nozzle 8 is wound onto a handling drum, and this drum applies a pulling force. The second pressure supply source is then actuated, and the high pressure chamber 15.16 of the pressure increase mechanism and the hydraulic pressure are The working chamber 6 of the plasticizing block 5 is filled with pressurizing liquid. The first pressure source is then activated, causing the piping and the second
Hydraulic oil is supplied to the low pressure chamber 21 of the first pressure increase mechanism 17 via the check valve 23 . Next, hydraulic oil at pressure P1 is supplied to the low pressure chamber 22 of the second pressure increase mechanism 18, and in this way, the first and second pressure increase mechanisms 17.
18 are alternately supplied with pressure. The pressure of the pressurizing liquid in the high pressure chamber 15 of this first pressure increasing mechanism 17 is P
The pressure is increased to 2. This pressure P2 is P2-KPl, where K is the pressure increase coefficient of the pressure increase mechanism. Then, the drawing drum rotates and drawing of the billet 10 of infinite length is started.

び現象が生じ、入口ノズル３の近傍の圧力が轟くなる。Then, as this billet is moved through the outer dynamic pressure tube 2, the pressurizing liquid in the boundary layer on the surface of the billet is drawn into the outer dynamic pressure tube together with the billet, and into the inside of the outer dynamic pressure tube. A liquid wedge phenomenon occurs due to the dynamic pressure, and the pressure near the inlet nozzle 3 rises.

時間がかかる。Further, as the billet passes through the inner dynamic pressure tube 7, a phenomenon similar to the above occurs also inside the inner dynamic pressure tube 7, and the pressure near the outlet nozzle 8 increases. Then, the metal material of this billet is plasticized by the high pressure in the hydraulic plasticizing block 5, and the tensile stress during drawing is reduced. This pressurizing liquid leaks out little by little and is consumed, but since the consumption amount is small, it takes a considerable amount of time until all the pressurizing liquid in the high pressure chamber 15 of the first pressure increasing mechanism is consumed. .

に維持される。When the pressurizing liquid in the high pressure chamber 15 decreases and the piston 19 moves to a predetermined position, the detector 27 detects this and the second Hydraulic oil is supplied through the check valve 24 . The inside of the working chamber 6 is pressurized to a high pressure by the high-pressure pressurizing liquid supplied from the high-pressure chamber 16 of the second pressure-increasing mechanism 18. Further, while the second pressure increase mechanism 18 is operating, the high pressure chamber 15 of the first pressure increase mechanism 17 is again filled with pressurizing liquid to prepare for the next operation. In this way, these first and second pressure increasing mechanisms 17, 18 operate alternately, and the billet 1
While the zero is being withdrawn, the pressure within the working chamber 6 is maintained at high pressure.
