Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a fan-shaped pouring machine used for casting, and a fan-shaped pouring machine with a 4% devised means for discharging hot water.

(Prior Art) Fan-shaped pouring machines have come to be widely used in casting because of the stable pouring flow and ease of controlling the pouring amount.

For example, as shown in FIGS. 1A and 1B, this fan-shaped pouring machine includes a pedestal 1, a reversible arene 5 provided on the pedestal 1 via a reversible bearing 2 so as to be freely reversible, and a reversible A fan-shaped ladle 5 is provided on the frame 3, and the fan-shaped ladle 5 is provided with rollers 4 and 4 (7) that are freely tiltable.
A pouring spout 6 is provided on one side of the tilting axis A, and a hot water receiving port [7] and a hot water outlet ■
'8 is provided.

After receiving the molten metal from the molten metal receiving lower, if the tilting cylinder (not shown) is driven, the medium ladle 5 will tilt around the tilting axis A, moving from the pouring molten metal [ ] 6 to the arrow B shown in the diagram. The molten metal is injected towards the σh type, which is abbreviated as σh, and the inverted cylinder is placed on the stand 1. When driven, the reversing frame 3 is reversed using the reversing bearing 2 as a fulcrum, and the remaining hot water is discharged from the discharge port 8 toward a discharge tray (not shown) as indicated by arrow C.

However, in the case of using the above-mentioned hot water draining means, the fan-shaped ladle 5 is
This requires a reversing cylinder 9 with a long stroke and a reversal cylinder 9 that has to be reversed by more than 0°.As a result, the fan-shaped pouring machine becomes larger as a whole and requires a large installation space, which increases equipment costs. There was a problem of increasing Furthermore, with the above-mentioned hot water drainage method, the falling point of the drained metal flow is not constant, so troublesome operations such as having to align the position of the hot water ladle are required, and in some cases, the installation of a guide gutter. It became necessary.

In addition, as a fan-shaped pouring machine, for example, Fig. 2 (al, (b)
As shown in FIG. 1, a motor 12 is connected to the tilting shaft 10 of the fan-shaped ladle 5 via a chain 11, and a drain port 8 is provided on the reverse tilting (clockwise rotation) side. Some models are designed to drain water to the side as shown by the arrow, but in this case, as in the example above, the falling point of the drained water flow must be constant, and when moving heavy objects, it is necessary to There was a problem that the drive system was poor and unreliable.Furthermore, the fan-shaped ladle is sometimes moved to a separately installed special hot water draining facility to drain hot water, but in this case, This not only requires extra equipment and installation space, but also requires time to transport, resulting in a reduction in the operating rate of the casting line.

(Objective of the Invention) In view of the above-mentioned problems of the prior art, the present invention has a compact structure, requires less installation space, and the falling point of the drained hot water flow is constant, eliminating the need for troublesome hot water draining operations. Then,
Our aim is to provide a fan-shaped pouring machine that can shorten the draining time as much as possible and improve the operating rate of the casting line.

(Structure of the invention) The purpose of this is to provide a drain port on the side opposite to the pouring port at the tilting axis of the fan-shaped ladle, and to provide a reversing cylinder on the pedestal that slightly reverses the reversing frame. This is accomplished by using a fan-shaped pouring machine that discharges the molten metal from the outlet.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

5-5 show the structure of a fan-shaped pouring machine according to the present invention. Note that the same components as those shown in FIGS. 1 and 2 are designated by the same reference numerals, and their explanations will be omitted. The feature of this embodiment is that the fan-shaped ladle 15 has a y-tilting axis A, and a drain port 18 is provided on the side opposite to the pouring port, and the drain port 18 is placed in a horizontal position slightly higher than the pouring port 6. The fact that it is opened, and the inverted frame 3
A reversing cylinder 19 having a short stroke length sufficient to make the drain port 18 slightly lower than the pouring port 6 is provided for reversing the melt. In FIG. 5, reference numeral 20 denotes an existing tilting cylinder fixed to the reversing frame 3, which is connected to the lower part of the fan-shaped ladle 15 via the frame 20'--, and functions to tilt the fan-shaped ladle.

With this structure, the upper surface is kept in a horizontal position.In order to receive the molten metal from the lower molten metal receiving part, and then inject the molten metal into a mold (not shown), the tilting cylinder 20 is driven to move the fan-shaped pan 15.
When the molten metal is tilted, since the pouring port 6 is located at a lower position than the draining port 18, the molten metal is discharged only through the pouring port 6 (arrow B). Therefore, when attempting to discharge the residual metal after casting is completed, by slightly raising the reversing cylinder 19, the draining port 18 will be at a lower position than the pouring port 6, and in this state, the tilting cylinder 20 will be driven. When the fan-shaped ladle 15 is tilted, the remaining hot water can be completely discharged through only the discharge port 18 toward the discharge ladle (shown by arrow C).

Since the drain port 18 is aligned with the vertical tilting axis A, the falling point of the drained metal flow is constant at I9X, which eliminates the need to move the drain pan or install a guide gutter. It has become. Further, since it is sufficient to employ a small reversing cylinder 19 and the reversing locus of the fan-shaped ladle 15 is also small, the present fan-shaped pouring machine has achieved miniaturization as a whole. Furthermore, according to this fan-shaped pouring machine, the time required for discharging the hot water is short, and it becomes possible to deal with not only the disposal of remaining hot water, but also the recovery of molten metal due to a drop in temperature due to component defects.

As shown in FIGS. 6 and 7, the fan-shaped pouring machine has a measuring device 21 interposed between the pedestal 1 and the reversing frame 5, and a reversing bearing 7 fixed to the pedestal 1. There is also a system in which the reversing cylinder 19 is removably supported by a jack-up cylinder 22, and the amount of molten metal poured can be controlled by the measuring device 21. It is set to have a longer stroke than the cylinder 22. Note that the same components as those shown in FIGS. 6 to 5 are given the same reference numerals. When discharging hot water, both cylinders 19 and 22 raise the reversing frame 6 by the stroke of the jack-up cylinder 22, separating it from the measuring device 21, and then moving the reversing cylinder 19 by the remaining stroke. When raised, the outlet 18 becomes lower than the pouring port 6, and then the fan-shaped pan 15
By tilting the molten metal, remaining hot water and the like will be discharged from the drain port 1B, and the same effect as in the previous embodiment can be achieved.

In addition, as shown in FIGS. 8 to 10, the fan-shaped ladle has a fan-shaped ladle 25 which has a spout 16 orthogonal to the tilting axis A. A drain port 28 is provided which opens in the same direction and is positioned higher than the pouring port 16. By supporting such a fan-shaped ladle with the same means as shown in FIG. 3, when discharging the hot water, by driving the reversing cylinder 19 and rotating the fan-shaped ladle 25 slightly N, the drain port 28 is opened. It becomes lower than the sprue 16, and the remaining hot water etc. will be drained from the drain spout 2B by the subsequent tilting operation. Here, the 8th
In Figures 1 to 10, 30 represents a tilting shaft, and 51 represents a furnace lid.

In the three embodiments described above, the drain port 18.28 may be located below the pouring ports 6, 16 when the fan-shaped ladle 15 is in a horizontal state. In this case, a stopper (plug, Install a slide gate, etc.) so that it opens only when draining hot water.

(Effects of the Invention) As described above in detail, the fan-shaped pouring machine according to the present invention has a drain port on the side opposite to the pouring port at the tilting axis of the fan-shaped ladle, and an inverted 7 V - It was equipped with a reversing cylinder that slightly reversed the arm, and the following effects were obtained by this.

■ The reversal locus is small and a small reversing cylinder can be used, making the fan-shaped pouring machine more compact as a whole and requiring less space for installation.

■ The falling point of the drained metal flow is constant, improving the efficiency of draining the hot water, and making it possible to omit unnecessary equipment such as guide troughs.

■ The time for discharging metal has been shortened as much as possible (within about 2 minutes), making it possible to greatly contribute to improving the operating rate of the casting line, allowing a wide variety of materials to be worked in, and saving energy by returning the discharged metal to the furnace.
