Definitions

  • the present invention relates to a device for transferring bars from a casting machine to a cooler.
  • the bars for example round or square, are transferred to the outlet of the curved or vertical continuous casting machines to the cooler, by various well known means.
  • Patent DE-AS-1,147,735 describes a device making it possible to introduce packets of bars or tubes into treatment baths so that they are inclined when entering the liquid.
  • a system of hoists comprising cables wound on two drums whose axes make a determined angle between them makes it possible to achieve this result.
  • the device is integral with a rolling cart on rails.
  • the means for capturing the load include stirrups, the positioning of which is not described, but is probably carried out manually.
  • Patent DE-C-959 678 describes a means for transferring long products comprising a horizontal beam, suspended below a carriage rolling on rails, by means of two hoists, a device making it possible to adjust the horizontality of the beam, in particular in the case where one of the hoists is more loaded than the other.
  • These devices do not include gripping means suitable for gripping continuous casting bars.
  • the device for transferring bars from a casting machine to a cooler which is the subject of the invention, comprises a carriage provided with gripping means and is characterized in that it also comprises at least one rail arranged longitudinally between the casting machine and the cooler, along which rail the carriage moves and at least two hoists mounted on said carriage which act directly or indirectly on the gripping means, each of these gripping means being constituted by a hook , comprising at its lower part a surface capable of cooperating with the surface of a bar, when it has descended above the latter, to make it pivot and come into its gripping position.
  • the hoists are actuated by a single motor mounted on the carriage and, advantageously, the axes of the pulleys of the hoists are perpendicular to the direction of the rail.
  • an inclined surface comprising a first part of large inclination on which the bar can be deposited by the gripping means, followed by a second part of lower inclination ending with a stop at the level from the cooler.
  • the device can be arranged to also be able to transfer the dummies from a storage area to the casting machine.
  • the device shown in Figure 1 comprises three rails (1) arranged longitudinally between casting machines and rockers not shown on the one hand, and corresponding coolers (2) on the other hand.
  • the three rails are installed on common gantries (3). On each of the rails (1) is provided a carriage as shown in FIG. 2.
  • This carriage is composed of a first beam (4) arranged longitudinally under the rail (1) in order to be able to move along this rail.
  • the beam (4) is provided with rollers (5).
  • a winch (6) On the beam (4) is installed a winch (6), the axis of which is transverse to the direction of the rail (1), actuated by a motor (7).
  • Hooks (11), for example two in number, are pivotally mounted under the beam (10).
  • the hooks (11) are connected to the beam (10) by means of yokes (12) supporting a longitudinal pivot axis (13) so that the hooks (11) can pivot in a plane perpendicular to the rail (1) .
  • the carriage can move longitudinally along the rails (1) and the lifting movement is exerted by the winch (6).
  • the hooks (11) pivotally mounted about the axis (13) supported by the yokes (12) have at their lower part an inclined surface (14) whose function will be described below. Furthermore, the hooks (11) also include bearing surfaces (15) capable of receiving a bar (16).
  • the bars (16) are gripped as shown in FIG. 3.
  • the carriage is first brought to the vertical of a bar (16) which has previously been placed in a horizontal position using a rocker on supports (17).
  • the beam (10) and the hooks (11) are lowered by means of the hoists (9).
  • the hooks (11) pivot around the axes (13) to come successively in the positions represented in (11a) and ( 11 b) in FIG. 3.
  • the hooks (11) have been sufficiently lowered, they can pivot in the opposite direction to come into the position shown in (11c).
  • the hooks (11) can then be reassembled using the winch (6) by lifting the bar (16).
  • the cart can. then transfer the bar (16) to the corresponding cooler, rolling on the rail (1).
  • the bar (16) is removed from the cooler (2) as shown in Figure 4.
  • an inclined plane (18) comprising a first part of strong inclination (19) and a second part of weaker inclination (20).
  • the slightly inclined surface (20) ends in a stop (21).
  • the hook (11) is lowered by the hoists (9) until the bar (16) comes into contact with the part (19) of the inclined plane (18) in the position shown in (16a).
  • the hooks (11) continuing their descent to the position (11d) where their beak (21) is retracted under the inclined plane (18), the bar (16) begins to roll on the strongly inclined part (19) then under the effect of the inertia continues to roll on the slightly inclined part (20) until it is stopped in the position (16d) against the stop (21) where it is then supported by the cooler (2).
  • FIG. 5 schematically represents an installation comprising a transfer device according to the present invention.
  • This installation comprises three vertical casting machines, not shown, at the outlet of which the bars, in particular round or square, are placed in a horizontal position using rockers (22).
  • Short roller conveyors (23) are provided to spread the rocker bars (22) and bring them under the end of the rails (1).
  • each of the rails (1) On each of the rails (1) is mounted a carriage as described with reference to Figure 2, and each of the rails (1) corresponds to a rocker (22) and a cooler (2).
  • the transfer device according to the invention also makes it possible to bring the casting dummies to the casting machines.
  • the storage area (24) of the casting dummies is arranged at the ends of the rails (1) opposite the rockers (22).
  • a conveyor formed for example of rails (25) allows the manikins to be brought from the storage area (24) to a location below the rail (1) corresponding to the casting machine on which it is desired to install the mannequin.
  • the invention therefore makes it possible to ensure, in a simple and economical manner, not only the transfer of the bars from the continuous casting machines to the cooler, but also the casting dummies from their storage area to the casting machines. .
  • the tracks of the carriage have been shown in the axis of the outlet of the casting lines, it is also possible, according to the invention, in particular for a machine with two lines to use a single trolley whose raceways are perpendicular to the axis of exit of the casting lines and which is able to serve both the cooler and the storage of mannequins.
