Definitions

  • the invention relates to a device for the precisely metered feeding of continuously rotating casting carousels with built-up molds, preferably for light metal casting.
  • a device for feeding fixed molds for casting large blocks (DE-A 2 406 896) with a fixed channel which can be fed by a pump and which leads to a rotatable, heatable pouring ladle which can be rotated and pivoted about a vertical axis with an articulated one the discharge end of which can be raised and lowered is provided for filling the fixed molds.
  • This device is only suitable for the intended purpose, i.e.
  • This device can give even less than the first suggestions for the precisely metered casting of high-quality small castings made of aluminum, because they do not deal with the filling of casting molds, but only with the distribution of large quantities of liquid metal on larger casting vessels, such as those used for steel are dealt with, whereby the associated weighing system does not permit the metering of very small quantities of metal.
  • these devices are alien to the subject matter of the invention because they are neither provided for the feeding and metering of a continuously rotating casting carousel with built-up molds, nor can they be converted in an obvious manner for this purpose.
  • Casting carousels with built-up molds as well as die casting machines are, as practice shows, still fed today via a ladle system.
  • a ladle that can be moved by a distance of approx. 3 to 4 meters between the die casting machine or the casting carousel and the stationary holding furnace is used.
  • the spoon moves to the furnace and dips vertically into the bath of molten metal, the immersion depth being scanned using contact rods. After the spoon is full, the spoon is raised and the excess metal in the spoon flows back into the metal bath.
  • the filled spoon is then moved to the pouring point and poured into the filling funnel or the metal feed channel with a length of 400 to 500 mm.
  • the invention has for its object not only to avoid the disadvantages of the known method described above, but also to significantly shorten the casting cycle and to increase the amount of metal per casting practically as desired and also to enable the possibility of fully automatic control of the entire casting process.
  • This object is achieved by the invention with at least one tiltable pouring vessel, a pouring channel connected downstream thereof, which is horizontally and vertically pivotable and horizontally displaceable, and devices for temporarily connecting the pouring channel near its outlet to the continuously rotating pouring carousel carrying the molds.
  • two tiltable pouring vessels are used, which alternately feed a metal distribution channel which opens into the pouring channel.
  • Automatic devices for mechanical cleaning of the metal outlet nozzle can also be provided after each or after a certain number of castings, or the metal outlet nozzle can be closed by means of a motor-operated plug, for example because of malfunctions in the hydraulics, the pouring channel cannot be raised.
  • 1 and 2 denote two pouring vessels, which are pivoted by means of hydraulic devices in tilting chairs 3 and 4 and alternately feed a metal distribution channel 5, the outlet of which opens into a pouring channel 6.
  • the casting trough 6 is provided with a metal outlet nozzle 9, which is located in the casting position exactly above the opening 10 of the mold 11.
  • the pouring channel 6 is mounted in a pivot bearing 15 so as to be pivotable about a vertical axis and also horizontally displaceable on a guide 16 in the direction of arrows D and E.
  • a temporary connection is provided between the two parts, and for this purpose a centering pin 18, which can be displaced by means of a hydraulic cylinder 17, is used, which into an opening of a coupling piece 19 on the underside of the trough 6 in the vicinity of their outlet can intervene.
  • the exchangeable metal outlet nozzle 9 can be closed by means of a plug 21 which can be actuated by a motor 20, for example in the event of a malfunction in the hydraulic system which prevents the channel from lifting at the end of the pouring cycle. If necessary, the nozzle cross-section can also be changed by means of the plug 21, provided that the entire nozzle is not to be replaced.
  • an automatic cleaning device (not shown), e.g. B. in the form of a pneumatically actuated metal brush, which automatically cleans the metal outlet nozzle 9 of residues between the individual pouring cycles, that is to say with the pouring channel 6 raised, and thus ensures a constant passage cross section.
  • the gutter can be detached, e.g. foldable channel cover 22, 23, not shown in FIG. 1, can be closed over most of its length, heating devices 24 and 25 being able to be provided in this channel cover to ensure a uniform casting temperature.
  • the pouring channel 6 is pivoted in the raised state by means of a hydraulic device (not shown) into the position corresponding to the beginning of the pouring 13. If the mold 11 built on the casting carousel 12 reaches this position, the casting trough is automatically lowered, so that the metal outlet nozzle 9 is above the opening 10 of the mold 11.
  • the channel 6 is coupled to the casting carousel 12, the metal flowing into the mold opening immediately after the channel has been lowered.
  • a narrowing of the cross section built into the trough for example in the form of a separating plate 26 with a small opening 27, enables a particularly smooth metal flow to be achieved during casting and at the same time residues of slag to be retained.
  • the filling process is monitored by built-in contact bars (not shown) in connection with the riser openings in the molds.
  • the metal flow rate is optionally via a Flow control group of the hydraulics regulated by changing the tilting speed of the casting vessel, the trough inclination and possibly also by adjusting the flow cross-section of the metal outlet nozzle 9 by means of the plug 21.
  • the casting is controlled by means of a predetermined casting time, whereby the smooth metal flow and the constant passage cross-section guaranteed with automatic cleaning of the metal outlet nozzle ensure a precisely metered amount of metal per casting.
  • the channel 6 can follow the continuous movement of the mold 11 without the continuous metal flow being impaired during the casting process.
  • the channel 6 is automatically tilted up by means of the hydraulic cylinder 8 and, if appropriate, the casting process is also ended by closing the metal outlet nozzle 9 by means of the stopper 21.
  • the centering pin 18 is retracted by means of the hydraulic cylinder 17, thus releasing the connection between the channel and the casting carousel.
  • the channel is then pivoted back into position 13 and is immediately ready for a new casting process.
  • an operating time per pouring vessel of 30 minutes. B. 30 seconds each and the pouring time can be 10-12 seconds and there is a sufficient period of approx. 25 minutes for refilling the pouring vessel not in use.
  • the heating devices 24 and 25 are also controlled automatically by appropriate temperature sensors.
  • the device according to the invention With the aid of a relatively simple control, it is possible by means of the device according to the invention, even with a continuously rotating casting carousel, for the entire casting operation, i.e. the alternate loading of the pouring channel through the two pouring vessels, the lowering or raising of the channel, its coupling with the casting carousel, the Metering of the amount of metal, the regulation of the temperature of the melt in the channel, the completion of the casting process, the uncoupling of the channel and its pivoting back to the starting position, to be carried out fully automatically.
  • the possibility of closing the metal outlet nozzle 9 and ensuring that this nozzle is positioned precisely over the pouring opening of the mold reliably prevents overflow and dripping even in the event of a malfunction.
  • the casting process can be interrupted at any time, without disruptions and complications when restarting.
