Definitions

  • the present invention relates to a method of coiling strip-formed material. by which is meant wire. strip and tubes. and a means for carrying out the method.
  • the invention is particularly valuable for coiling material in hydrostatic extrusion. which is a method in which the manufactured product leaves the press at a great speed and suddenly stops at the end of the pressing cycle. It is particularly suitable for coiling-thin-walled tubes. which are easily deformed.
  • the Prior Art Strip-formed material can be gathered up in stationary barrels or on rotating drums. When it is gathered in stationary barrels. the material will be rotated one turn around its own axis for each turn in the barrel. For thin wire this causes no inconvenience or problems. For material with a cross section which is not round or tubes. this rotation around the longitudinal axis cannot. as a rule. be tolerated. The material must be coiled on a rotating drum.
  • wire. profile or tube. is shaped with the desired cross section since the material in a billet. which is enclosed in a pressure chamber. is subjected to a high hydrostatic pressure and in this way pressed out through an opening in a die.
  • the shaped product leaves the die at a high speed. which may be of the order of IS m/sec. when manufacturing copper tubing.
  • the tube length which can be obtained from a billet depends on the size of the billet and the cross section of the tube and can be from 300 to 400 metres.
  • the pressing process is interrupted before the billet is completely consumed. When the pressing is interrupted. the material flow through the die ceases almost instantaneously. This circumstance makes it difficult to coil the product especially when this is a tube which is easily deformed.
  • Known coiling devices with a rotating drum of known kind must be stopped exactly when the extrusion ceases. in order to avoid a jerk or stretching of the product which causes damage. This refers particularly to extrusion of thinwalled tubes.
  • the problem is solved by inserting the product. a rod. wire or a tube. tangentially into a first hollow drum. the inner surface of which has a peripheral speed which is substantially the same as the speed of the incoming product.
  • the product is wound up inside the drum. thus on an inner coiling surface.
  • Inside this drum there is a second drum having an outer coiling surface.
  • This drum is rotatable independently of the first drum. It is normally stationary when a product is wound up in the first drum. When the extrusion is finished and the supply of the press product suddenly ceases. the product is stretched because of the rotation of the first. outer drum and will thus be coiled up on the inner drum without being subjected to damaging strains.
  • the invention also relates to a means for carrying out the method.
  • Said means comprises a first hollow rotatable drum. having an inner coiling surface. and a second drum. having an outer coiling surface.
  • the second drum is arranged inside the first drum and is rotatable. as a rule. for winding on the last part of a press product.
  • the equipment of course comprises driving devices and handling devices of various kinds.
  • FIG. I shows in section equipment in which the inner drum with wound-on material is lifted out of the outer drum when a coil of material is to be removed.
  • FIG. 2 shows equipment in which a coil of material is deposited on a transport car.
  • FIG. 3 shows in a larger scale supporting member for a coil in the embodiment of FIG. I.
  • I designates a conical hollow drum having an inner coiling surface 2. It is supported by a disc 3 with a hub 4 and is rotatably mounted by bearings 7 to rotate around a pin 5, which is fixed to the floor 6.
  • the drum is driven by a motor 8 through the gear wheel 9 on the motor shaft 10 and a gear wheel I I on the hub 4.
  • a second drum I5 having an outer coiling surface I6.
  • the drum is provided with discs 17 and I8 and at its lower part with a hub [9.
  • the inner drum I5 can be lifted out of the outer drum by means of a lifting device. shown as a lifting cylinder 27 with a lifting bar 28 which is connected to the disc I7. Between a plate 29 on the bar 28 and the disc 17 is a bearing 30. Thus. the drum can rotate in relation to the bar 28 in the position shown as well as in an elevated position. A car 31 running on rails 32 can be pushed in below the drum I5 when this is in its elevated position.
  • a guide tube 33 for a press product 34 is located and shaped in such a way that the press product is inserted tangentially into the outer drum 1.
  • the supporting member 26 is shown in a larger scale in FIG. 3. It is journalled upon a pin in a slot 76 in the bottom disc I8. It is locked in the position shown by means of latch 77 journalled upon a pin 78 between two brackets 79.
  • This latch is operated by an operating cylinder 80 which is fixed to the bottom disc 18 and attached to the latch 77 by means of its operating rod 8
  • the latch 77 is withdrawn by the cylinder 80.
  • the coiled product 34 will tilt the member 26 within the slot 76 and fall down upon a car 3I moved into a position below a lifted drum.
  • FIG. 2. 4 designates a conical drum having an inner coiling surface 42. It is suspended in a conical disc 43 which is rotatably mounted in a ring 44 by a bearing 45. The ring 44 is suspended on the underneath side of the floor 46.
  • the drum is driven by a motor 47 through the V-belt 48 running over the grooved pulley 49 on the shaft 50 of the motor 47 and over the scored pulley S] of the drum 41.
  • inside the drum 41 is a second drum 52 having an outer coiling surface 53. This drum is suspended with the discs 54 and 55 on a shaft 56 which is mounted in the hub 57 in the floor 46 by bearings 58.
  • the drum 52 is pro- ⁇ ided at its lower part with a number of radially manoeuvrable coil supports 65 ⁇ hich are mounted in slits 66 in the drum S2 and in slits 67 in the ring 68. which is suspended in the disc 55.
  • the supports 65 can he operated radially between the position shown in the figure and a retracted position by means of an operating device 69 such as a hydraulic cylinder.
  • a press product 70 is inserted tangentially into the drum 4! by means of a guide tube 7] which passes the opening 72 in the floor 46 and the ring 44.
  • the coiling means operates in the following way.
  • the outer drum 1 or 41. is brought to rotate at such a speed that the coiling surface 2 or 42 will attain a peripheral speed which corresponds to the inlet speed of the press product 34 or 70.
  • the press product will lay itself on the inner coiling surface 2 or 42.
  • the outer drum continues to rotate but the supply of the press product ceases.
  • the press product 34 or 70 is firmly connected with the residual billet in the pressure chamber. and its movement is therefore stopped instantaneously.
  • the press product nearest the guide tube 33 or 7] is stretched.
  • the coil supports are retracted with the help of the operating devices 69 and the coil falls down on the car 73.
  • Method of coiling strip-formed material which comprises leading the material tangentially into and coiling it inside a first hollow drum rotating at such a speed that its peripheral speed is substantially the same as the speed of the material. suddenly ceasing the supply of material. and thereafter coiling the material around a second drum arranged inside the first drum. said second drum being stationary or rotating at a low speed.
  • Means for coiling strip-formed material comprising a first hollow rotatable drum having an inner coiling surface and a second drum within the first drum and spaced therefrom having an outer coiling surface.
