Definitions

  • the invention relates to a casting device for metals with a continuously revolving support element, on which a plurality of mold parts movable in pairs in relation to one another, each representing mold space sections, can be carried, and with adjusting elements by means of which the mold space - which is located on a section of the support element circulation path is formed by a part of the mold part pairs which also abut one another in the circumferential direction - closed in the area of the metal feed and - seen in the circumferential direction - can be opened at a predetermined distance from it.
  • a casting device of the type mentioned in the form of a casting wheel is known, the mold space of which is delimited on the one hand by the wheel rim and on the other hand by pivotally held mold halves. These can be brought into a closed position by means of cylinders, in which they seal the mold space from the outside, or can be moved into an open position by pivoting away from the wheel rim, which enables the strand to be transported away from the area of the casting wheel.
  • DE-C3-21 09 254 describes a casting device with a caterpillar mold, which is formed by two rotating caterpillar chains interacting in the mold space area. This known casting device also does not allow the mold space cross section to be adapted to the shrinking processes already mentioned.
  • the invention has for its object to design a casting device with reasonable technical effort in such a way that it has a straight mold room; this should be designed in such a way that the shrinkage-related shrinkage processes can be at least partially compensated for.
  • the object is achieved by a casting device with the features of claim 1.
  • the basic idea of the invention then consists in the use of an endless chain running oval with chain wheels and pairs of mold parts that are movable relative to one another, which are guided over suitably aligned support rollers at least in the mold space area and each temporarily form a mold space section with one another.
  • the interaction of several pairs of mold parts that follow one another in the circumferential direction creates an uninterrupted mold space in an area in which the endless chain runs in a straight line; the length of which is determined by the number of pairs of mold parts whose mold parts (between the metal feed area and the mold space end) assume the closed position.
  • a change in the mold space cross-section to adapt to shrinkage processes is made possible in that all contact surfaces over which the mold parts of each mold part pair can be supported against each other with respect to a reference plane (with a horizontal arrangement of the mold space, for example, with respect to a horizontal plane through the mold space -Longitudinal axis) have the same angle of inclination and alternately overlap in the closed position; the corresponding angle of inclination can in particular also be 0 ° .
  • the inclination of the mold space extending between the chain wheels can be arbitrary, ie it can be arranged horizontally, inclined or also vertically.
  • the contact surfaces between the mold parts of each mold part pair are preferably aligned in such a way that a displacement transversely to the longitudinal axis of the mold space does not result in a change in the height dimension of the mold part pairs.
  • the casting device has a mold space that is rectangular in cross section
  • the contact surfaces of the interacting mold parts run parallel to its upper or lower wall.
  • Each mold part accordingly carries a mold wall section, which - seen perpendicular to the longitudinal axis of the mold space - is angular (claim 2). If, for example, a mold part forms the lower wall and left side wall of the relevant mold space section, this includes associated second mold part a section of the top wall and right side wall of the mold space.
  • the endless chain is equipped with roller bearings that are supported at least in the mold space area on a guideway (claim 3).
  • the connection between the mold part pairs and the endless chain is preferably designed in such a way that each mold part pair on the endless chain is assigned two pairs of rolling bearings which follow one another in the circumferential direction (claim 4); Two adjacent pairs of mold parts therefore each have a common pair of roller bearings on the endless chain.
  • the mold parts 6a, 6b of each mold part pair 6 are movably attached to one another via a rotary connection 19 with a hinge pin 19a which is connected via two holding plates 19b and an intermediate counterbearing 19c is immovably connected to the mold part 6b or movably to the mold part 6a.
  • the counter bearing 19c is supported with a play s on the hinge pin 19a, so that the mold parts interacting in pairs and the associated mold wall sections 6c, 6d can also be laterally displaced in the closed position shown in FIG. 5.
  • the embodiment of the subject matter shown in FIG. 7 differs essentially only from the previously described embodiment in that the rotary connection 19 between the mold parts 6b and 6a is additionally equipped with a spring element 31 in the form of a torsion spring. This is connected to the parts 19b and 19c at the same time and exerts a restoring force, by means of which the movable mold part 6b is pivoted up clockwise as soon as the upper support roller 20 is no longer supported on the closing guide 29 outside the mold space area. Since the mold part pairs 6 are automatically moved into the open position under the action of the spring element 31, the use of an opening guide can be dispensed with.
  • the spring element is designed and / or held on the parts 19b and 19c in such a way that it does not hinder a displacement of the mold parts 6a and 6b lying against one another in the order of a few tenths of a millimeter.
  • the hinge pin 19a engages with a sufficiently dimensioned play s in the counter bearing 19c of the stationary mold part 6a.
  • the spring element can also be designed and arranged differently than shown; in particular, the use of a compression spring is possible, which is supported on the counter bearing 19c between the mold wall section 6d and the support roller 21 on the movable mold part 6b.
