Abstract
1,208,631. Drawing. MANNESMANN-MEER A.G. 29 Jan., 1968 [28 Jan., 1967], No.4481/68. Heading B3P. A drawing trolley has a damping device which includes a plunger piston 25 lying against the rod or tube being drawn and energy storage means 19 for absorbing the energy suddenly released by the drawn rod or tube as it leaves the die. After the front end of the material to be drawn has engaged a contact plate 24 of the piston 25, jaws 12, 13 are closed to clamp the material. When the trailing end of the material has left the die and the jaws 12, 13 have been opened, the plunger piston 25 is pushed by the drawn material into a cylinder 23 to cause the hydraulic fluid such as oil to open a spring- biased damper 20 and to flow into a compartment 22 of the cylinder 23. A piston 40 is thereby moved in the pressure storage chamber 19 to compress the gas such as nitrogen therein causing the whole of the energy released by the drawn material to be absorbed until the latter comes to a standstill. The damper 20 is closed to prevent the material accelerating in the opposite direction and the material drops from the trolley. As the trolley remains stationary or returns to its initial position, the hydraulic fluid gradually flows from the compartment 22 through bores 39 in the damper 20 until the plunger piston 25 reaches its initial position. The compartment 22 and the chamber 19 are respectively connected to a storage chamber (59) (Fig. 2, not shown) and a storage tank (54) which serve to compensate for losses due to leaks.
