Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention attaches and detaches a latch weir that is used to guide the injection of molten metal from a ladle to a mold and attaches and removes a latch weir cover to the latch weir. The present invention relates to a hanging weir supply / recovery device having a hanging weir cover attachment / detachment function.

[0002]

2. Description of the Related Art Conventionally, an operator attaches a hanging weir to a mold that is sent to a pouring position before pouring the molten metal from a ladle into the casting mold, and the hanging weir that has been used after pouring is re-worked. The work of attaching and removing the weir, such as the person removing it from the mold, was performed manually. Further, since there is a risk of damaging surrounding equipment if the molten metal is scattered from the hanging weir at the time of pouring, a lid for covering the opening except the pouring portion is attached to the hanging weir by manual work.

[0003]

As described above, in the conventional method in which the work of attaching / detaching the weir to the mold and the work of attaching / detaching the lid to the weir are wholly dependent on manpower, workability is extremely high. Poorly, it is not possible to fully utilize the improvement in productivity due to the efficient casting that accompanies the introduction of the automatic pouring device. In particular, since the weir after pouring is heated and in a high temperature state, it is extremely dangerous to immediately remove it manually.

The present invention has been made in view of the above circumstances, and it is possible to achieve an improvement in productivity while ensuring safety by automating the work of attaching and detaching the latch and lid. It is an object of the present invention to provide a hanging weir supply / recovery device having a detachable function.

[0005]

In order to achieve the above object, a latch weir supply / recovery device having a latch weir cover attachment / detachment function of the present invention is a latch weir for a gantry provided above a mold transfer line. A hanging base having a hanging clamp is provided so as to be able to move up and down and move in the mold conveying direction, and a hanging weir suspended at a predetermined hanging position via the clamp is used as a mold. It is transported to a predetermined set position in the transport direction and sent to the pouring position.It is attached to a mold, and after pouring is completed, the hanging weir is lifted and removed from the mold returned to the set position and transported to the predetermined hanging position. A hanging weir suspending / conveying device, and a lid forming a hanging weir cover that closes the opening of the hanging weir except the injection part when the hanging weir is conveyed by the hanging weir suspending / conveying device is provided on the hanging base side. It is equipped detachably.

By introducing the hanging weir suspending and conveying device having the above-described structure, it is possible to automate the work of attaching and removing the hanging weir to the mold, and save labor. Further, in the manual work at the time of removal, in order to ensure safety, it is necessary to wait until the hanging weir in the high temperature state after pouring has cooled, but in the present invention, the hanging weir should be immediately removed from the mold. It is possible to improve productivity significantly in combination with automation. Further, at the time of mounting the hanging weir by the hanging weir suspending and conveying device, the opening of the hanging weir is closed by the lid on the side of the hanging base except for the injection portion, so that the molten metal is scattered from the edge of the opening of the hanging weir. It is possible to prevent damage to the equipment.

Here, as a preferred structure, the lid is detachably attached to the hanging base through a cylinder provided in the hanging base.

Next, the operation of the apparatus having the above configuration will be described. The ladle 2 that has received the molten metal travels through the self-propelled carriage 3 and is conveyed to a predetermined pouring position P, while the mold 5
When reaches the predetermined set position S, the hanging weir suspending and conveying device 9 moves to the carry-in side suspending position D2, lowers the suspending base 26 by extending the piston rod 25a of the cylinder 25, and then suspends the suspension. The clamp portions 36, 3 are provided below the both end projections 8a, 8a of the hanging weir 8 after cleaning located at the lower position D2.
Insert 6 respectively. Then, the suspension base 26 is displaced upward by contraction of the piston rod 25a of the cylinder 25 to suspend the latch weir 8 via the clamp portions 36, 36.

The hanging weir 8 suspended by the hanging weir suspending and conveying device 9 is conveyed to the set position S, and the cylinder 2
When the piston rod 25a of No. 5 is extended, the latch weir 8 is displaced downward and is mounted on the mold 5 waiting at the position S. At this time, when the piston rod 38a of the lid opening / closing cylinder 38 of the hanging base 26 is extended, the lid 40 is displaced downward, and the opening of the latch 8 is opened by the lid 4.
Blocked by 0. When the lid opening / closing cylinder 38 is not provided, the piston rod 25a of the cylinder 25 is further extended to displace the lid 40 downward, and the lid 40 is attached to the latch weir 8.

The mold 5 to which the latch 8 and the lid 40 are attached is sent to the pouring position P, where the molten metal from the ladle 2 is poured through the latch 8. At this time, the lid 40 prevents the molten metal from scattering.

When the casting mold 5 after the molten metal is returned to the setting position S, the hanging weir suspending and conveying device 9 moves the hanging weir 8 on the casting mold 5 through the clamp portions 36, 36 in the same manner as described above. Since the lid body 40 is lifted and the lid body 40 is lifted via the lid body holding plate 37, the latch weir 8 and the lid body 40 are removed from the mold 5, and the mold 5 from which the latch weir 8 is removed is moved by the mold transport line 4 to the rear side. Sent to the process.

As described above, since the hanging weir suspending / conveying device 9 can suspend the hanging weir 8 and the lid 40 and automatically attach them to the mold 5 before pouring, no labor is required and the work can be performed quickly. Can be realized. Furthermore, even after the pouring, since the latch weir 8 and the lid 40 can be automatically removed from the mold 5, the work can be safely carried out even if the latch weir 8 heated at the time of pouring is in a high temperature state. Besides,
There is no need to wait for the weir 8 to cool, and
Can be removed immediately, improving productivity.

The latch weir 8 removed from the mold 5 is transferred to the unloading side hanging position D1 by the latch weir suspending and conveying device 9 and transferred to the unloading portion 13A of the latch weir loading / unloading device 13. Then, the latch weir 8 is at the carry-out side hanging position D1.
Is sent to the weir cleaning processing device 10 side, where it is held by the moving mechanism 12 and moved to the reversing device 11, where the molten metal and the like adhering to the inside of the reversing device 11 is removed and cleaned.

The weir 8 after the cleaning process is the moving mechanism 1
After being held by 2 and transferred to the carry-in section 13B of the lock weir carry-in / out apparatus 13, the carry-in section 13B carries the product to a predetermined carry-in side hanging position D2 and waits for the next mold 5. Become.
