Abstract
A casting machine (1) having a device for controlling a movement of the foundry ladle (9), and a control cam (33) having a roller path (29) on which the foundry ladle (9) is movably carried is provided. The casting machine further includes a lifting device for lifting the foundry ladle (9) prior to tilting and lowering of the foundry ladle (9) once it has been emptied for filling it with molten material. The foundry ladle (9) is mounted so as to swing about a vertical axis (A) from the casting position to an exchange position.
Description
- The invention is directed to a casting machine according to the preamble of the
independent claims 1 and 4. - From WO 97/24200 a method and a device are known for controlling the movement of a foundry laldle with a low casting height in a casting arrangement. This method and/or this device allows by purely mechanical means the performance of the tilting movement in an advantageous manner. However, the exchange of the empty foundry ladle for a foundry ladle filled with new melt is unpractical. Furthermore, the feeding of the foundry ladle to the casting boxes, which are usually guided along the casting arrangement on cars, must occur by a separate drive, i.e. on conveyers which run lateral to the drive path of the casting boxes. During tilting, the foundry ladle is guided on two parallel positioned curved paths; additionally it is suspended on both sides between the curved paths. This dual suspension complicates the exchange of the empty foundry ladle for a newly filled one quite considerably, because during the transfer of the foundry ladle the latter must be lifted out of the guides.
- The objective of the present invention is to create a casting machine, by which the foundry ladle can be guided purely mechanically on curved paths and can optimally perform a tilting movement. Another objective of the invention comprises that the suspension of the foundry ladle is provided such that an easy exchange of the empty foundry ladle for a full one is enabled.
- This objective is met through the features of
claims 1 and 4. - By the unilateral suspension of the foundry ladle at a control cam using two pairs of roller paths, namely an interior one and an exterior one, it is achieved, on the one hand, placement of the foundry ladle on the floor and release of the foundry ladle from the suspension and/or the lifting of a foundry ladle filled with melt from said place into the initial position for tilting, and, on the other hand, to perform the tilting movement such that the outflow can occur in a best possible manner. Furthermore, by linking a control cam to a vertically positioned rotational axis, the foundry ladle can be rotated together with the control cam around said axis and can be lowered for the transfer to a transportation device, which removes empty foundry ladles and feeds new ones. Additionally, performance of both the lifting and the lowering movement as well as the tilting movement by a single drive is also achieved.
- Using an illustrated exemplary embodiment, the invention is explained in greater detail. In the drawings:
-
FIG. 1 a is a layout of a casting box conveyer having four casting boxes and a casting machine in the casting position and in the exchange position, -
FIG. 1 b is a side view of a casting machine, -
FIG. 1 c is a view of the casting machine from the front, -
FIG. 1 d is a partial layout of the casting machine after the foundry ladle has swiveled out around the axis A, -
FIG. 2 is a side view of the control cam of the carrying car and the foundry ladle set down in front of it, in dot-dash lines, and in a raised position for the tilting movement, -
FIG. 3 is a perspective view of the control cam and of the foundry ladle suspended from the carrying car, -
FIG. 4 is a top view of the casting machine according toFIG. 2 , -
FIG. 5 is a side view of the control cam of the carrying car and the foundry ladle in front of it in a raised position and in a position at the beginning of the casting process, and -
FIG. 6 is a side view of the control cam of the carrying car and the foundry ladle in the position at the beginning of the casting process and in the position at the end of the casting process in a maximally tilted position. - In a schematic representation according to
FIGS. 1 a through 1 d, a casting machine according to the invention is indicated withreference number 1, which is arranged in front ofcasting boxes 3.Several casting boxes 3 can be guided past thecasting machine 1 onconveyers 5. Thecasting machine 1 can be locally fixed or preferably be movable onconveyers 7 as well, in the latter case in order to be able to follow the casting boxes during the casting process, for increasing productivity. Further, inFIGS. 1 a and 1 d, in dot-dash lines, thefoundry ladle 9 is discernible in a swiveled position. In this position, thefoundry ladle 9 can be set to the floor and removed by a transportation device. From this set down position, anew foundry ladle 9, i.e. one filled with new melt, can be accepted by thecasting device 1. Further, inFIG. 1 d a pivotal axis A is discernible, which allows the pivoting of thefoundry ladle 9 from the casting position into the set down and exchange position. - Based on the perspective representation in
FIG. 3 , the primary parts of thecasting machine 1 according to the invention are described. In the foreground, thefoundry ladle 9 with the spout 11 and thespout stone 13 arranged therein are discernible. At both sides on the upper rim of thefoundry ladle 9, receivingholders 15 with catchingslots 17 are discernible. Thereceiving holders 15 serve to allow the transportation of thefoundry ladle 9 via a transportation device. On the lateral surfaces of thefoundry ladle 9, not discernible inFIG. 3 , holdingdevices 19 are mounted (compareFIG. 4 ) here, from which thefoundry ladle 9 can be suspended from aholding plate 21 on ancarrying car 23. At theholding plate 21, theholding disks 20 are arranged, which engage theholding means 19 from the bottom. - The carrying
car 23 comprises two pairs of rollers, namely an upper pair ofrollers 25 and a lower pair ofrollers 27. The upper pair ofrollers 25 run on theupper roller path 29; the lower pair ofrollers 27 runs on the lower roller path 31 (also compareFIG. 2 .) Theupper roller path 29 is on anupper control cam 33; thelower roller path 31 on a lower control cam 35 (FIG. 2 .) - Based on
FIGS. 2, 5 , and 6, the movement process of the foundry ladle is described from the time of accepting a ladle filled with melt to the setting down of the emptiedladle 9. InFIG. 2 , in dot-dash lines, theladle 9 is shown set down onto thefloor 37. Also discernible from the same figure is thefoundry ladle 9 raised by the distance z. Here, the lower pair ofrollers 27 run along the linearly extendingpath sections 39 and the upper pair ofrollers 25 along the upper, also linearly extendingpath sections 41. Both pairs ofrollers linear path sections intermediate section 43 of theupper roller path 29 and alower section 45 of thelower roller path 31. These twointermediate sections intermediate section 43, in particular. This leads to a displacement of the spout 11 from point C to point B (cf.FIG. 5 ). - After having passed through said
intermediate sections rollers roller path sections foundry ladle 9 from a position shown at the bottom ofFIG. 6 to the position shown at the top ofFIG. 6 . The tilting angle amounts to the angle alpha (FIG. 6 .) After having finished the filling process of amold 3, the carryingcar 23 with thefoundry ladle 9 returns to the starting position and, after the forward movement of thecasting box 3, a subsequent casting box is filled in the same manner. - As soon as the
foundry ladle 9 is empty or the melt remaining in thefoundry ladle 9 is insufficient for filling another mold in thecasting box 3, the carryingcar 23 returns to the starting position, subsequently the carryingcar 23 pivots counter-clockwise around a vertical axis A by approx. 90° (cf.FIGS. 1 a and 1 d.) Now, the carryingcar 23 with theempty foundry ladle 9 rolls downwards until the latter rests on thefloor 37. By further lowering the carryingcar 23, theholding disks 20 move out of theholding plate 21 so that thecasting machine 1 can move forward and reverse on theconveyer 7 and can accept, lift, and pivot thenext foundry ladle 9, filled with melt, and continue the casting process. The set down,empty foundry ladle 9 is picked up by a transportation device, such as a forklift, crane, or the like, and is replaced by a new, filledfoundry ladle 9. - The pivot axis A can support the
control cams car 23 and the holding plate 21 (not shown.)
