Description

[Detailed Description of the Invention] This invention relates to an automatic water supply device that automatically supplies molten metal (hereinafter referred to as molten metal) to a pouring device for a mold in a foundry, for example.

In foundries, pouring molten metal into molds has traditionally been done manually by tilting a ladle suspended from an overhead lane, but in order to save labor and automate the pouring process, it is now possible to pour molten metal into molds automatically using mechanical power. The introduction of pouring equipment that pours hot water is becoming popular.

When considering the supply of molten metal to the pouring device when introducing a pouring device, it is necessary to hold the molten metal melted in the melting furnace in a holding furnace,
A common method is to supply molten metal from a holding furnace to a pouring device.

However, it is difficult to arrange the holding furnace and pouring device in such a way that the holding furnace and pouring device are placed close to each other, and the outlet of the holding furnace is above the inlet of the pouring device so that molten metal can flow and be supplied. Very limited and often difficult due to layout issues.

In such cases, a method has been used in which the molten metal from the holding furnace is received in a ladle suspended in an overhead lane, carried to the receiving port of the pouring equipment, and the ladle is tilted. .

On the other hand, in order to obtain the effect of inoculation performed before pouring hot water, the hot water storage capacity of the hot water pouring device cannot be increased and the capacity is relatively small, so the hot water supply cycle in the ladle is extremely short, and the Multiple dedicated operators are required to operate the running lanes or tilt the ladle, and hot water pouring equipment introduced for the purpose of labor saving and automation becomes ineffective when hot water is supplied using a ladle suspended in the overhead running lane. There was a drawback that

The purpose of this invention is to provide an automatic hot water supply device that does not require a dedicated operator to supply molten metal to the pouring device.

FIG. 1 shows an embodiment of this invention, in which 1 is a tap opening of a holding furnace, 2 is a ladle, 3 is an inclined frame to which the ladle 2 is fixed, and 4 is a cart.

The tilting frame 3 is connected to the truck 4 through a joint on one side, and to a hydraulic cylinder 5 through a joint on the other side.

The other end of the hydraulic cylinder 5 is connected to the truck 4 by a joint.

Wheels 7 driven by a drive device are attached to the truck 4, and a hydraulic pressure generating device 6 that drives a hydraulic cylinder is also attached.

8 is a rail laid on the floor surface, 9 is a lifting frame, 10 is a rail installed on the lifting frame 9, 11 is a trolley rotation device that fixes the trolley 4 to the lifting frame 9, and 12 is installed on the upper part of the lifting frame. The attached pulley 13 is a rope that engages with the pulley 12, and 14 is a winding device that winds up the rope 13.

Reference numeral 15 is a steel tower, on which are attached a display gear ff 114, a guide device for vertically raising and lowering the elevating frame 9, and a tower 16. Reference numeral 17 is a metal receiving port of a pouring device.

2 and 3 are detailed views of the truck fixing device 11. In FIGS. 2 and 3, 18 is a stopper, 19 is a hook lever, and 20 is a cylinder, one end of which is connected to the joint 2.
1 to the lifting frame 9.

The hook lever 19 is rotated by being driven by the cylinder 20 by a joint 22 attached to the lifting frame 9 and a joint 23 coupled to the piston rod of the cylinder 20.

24 is an arm attached to the trolley 4, and the hook lever 1
It is designed to engage with 9.

In the automatic hot water supply system configured as described above, after hot water is received from the outlet 1 of the holding furnace into the ladle 2 fixed to the tilting frame 3,
The wheels 7 are rotated by the drive device in response to a signal issued by the operator of the holding furnace, and the cart 4 travels on the rails 8.

The elevating frame 9 is waiting at a predetermined position, and the rail 10 is at a level and an interval from the rail 8 that allows the axle 7 to pass through.

When the bogie 4 that has been traveling on the rail 8 moves onto the rail 10 and stops at a predetermined position by a position detector (not shown), the bogie fixing device 11 in the state shown in FIG.
0 operates and the hook lever 19 joins) 22.
23 and engages with an arm 24 attached to the truck 4, resulting in the state shown in FIG. 3, where the truck 4 is fixed to the lifting frame 9.

When the operation of the bogie fixing device 11 is detected by a detector (not shown) and the hoisting device 14 is operated based on this signal, the pulley 12
The rope 13 engaged with the tower 1 is wound up, and the lifting frame 9
It ascends vertically while being guided by a guide device (not shown) attached to the inside of the container.

When the lifting frame 9 stops after rising to a predetermined position by a position detector (not shown), a signal is sent to the hydraulic pressure generator 6 mounted on the truck 4, and when the hydraulic cylinder 5 operates, the tilting frame 3 Since it is rotatably connected to the frame 4 by a joint, it tilts around this joint.

The ladle 2 is fixed to the tilting frame 3 and tilts together with the tilting frame 3, so that the molten metal held in the ladle 2 is transferred to the tow 16.
The hot water is discharged to the hot water receiving port 17 of the hot water pouring device.

After the time has elapsed for all of the molten metal in the ladle 2 to be tapped, the operations in reverse to the above operations are performed in sequence.

In other words, the hydraulic cylinder 5 operates to return the tilting frame 3 to the horizontal position, the hoisting device 14 reverses, the elevating frame 9 descends and stops at a predetermined position, and the cylinder 20 of the bogie fixing device 11 operates to fix the bogie. Device 11 is released.

Since the wheels 7 driven by the drive device rotate in reverse, the cart returns to the ladle 2's receiving position.

In the above, the start and end signals of each operation are obtained by a position detector such as a mechanical limit switch or a proximity switch, or a timer.

In the above embodiment, the tilting frame was tilted by a hydraulic pressure generating device and a hydraulic cylinder, but the same operation can be expected even if another driving source such as a combination of a screw and a nut is installed on the cart and the tilting frame is operated. Instead of driving the lifting frame with a hoisting device, rope, or pulley, a rack and pinion combination, screw and nut combination, hydraulic cylinder, or chain drive source can be attached to the steel tower to drive the lifting frame up and down within the steel tower. Similar behavior can be expected.

By the way, in the above explanation, we have described the case where molten metal is supplied from the holding furnace to the pouring device, but it goes without saying that it can also be used to supply other molten metals, and it can also be used for traveling, lifting, lowering, etc.
Of course, each tilting operation can also be performed by manual switch operation.

As explained above, this invention allows the ladle to be moved horizontally, vertically, and tilted using the ladle, traveling cart, lifting frame, and tilting plate to automatically move the molten metal. Regardless of the arrangement with the pouring device, for example, if the holding furnace and pouring device are separated, or if the pouring device's inlet is placed above the holding furnace outlet, it is easy to automatically melt the metal. Since this method can supply molten metal to the pouring device, an operator is not required to supply the molten metal to the pouring device, resulting in labor savings.
