Description

[Detailed Description of the Invention] This invention provides a method for lifting a push-up rod for demolding in a continuous casting device such as an anode for copper electrolytic refining.
It relates to automatic devices for pushing.

For example, a generally known continuous anode casting apparatus has a rotary casting plate 1, as shown in FIG.
A plurality of molds 2 are provided along the circumferential direction on the upper surface of the mold, and as shown in FIG.
Push-up rods 4 for demolding are inserted into holes 3 formed at predetermined positions so that they can protrude upwards, and the rotary casting machine 1 is rotated as shown by arrow A in Fig. The cast product (anode) that is poured, cooled during rotation, and solidified is picked up by a lifting machine 5 at a point, and this operation is continuously performed as the rotary casting plate 1 rotates to produce an anode. It is.

In this case, the push-up rod 4 closes the hole 3a as shown in FIG. 3 from pouring to take-up, and is pushed up from the back side of the mold 2 at the take-up stage as shown in FIG. The anode 6 is made to protrude from the mold 2 and removed from the mold.

Then, when the anode 6 is lifted up, the push-up rod 4 is lowered again to close the hole 3a (see Fig. 2) of the mold 2 so that the next pouring can be performed. If a foreign object gets caught between the hole opening 3a and the push-up rod 4, the hole opening 3a may not be completely blocked, and molten metal may enter there, making it impossible to perform normal casting. .

That is, as shown in Fig. 2, the hole 3a and the upper end of the push-up rod 4 are tapered fitted to seal the hole 3a, and when the push-up rod 4 is completely lowered, the push-up rod 4 cannot be pushed up The rod 4 sinks into the hole 3a and the top surface becomes flush, but if the hole 3a is clogged with foreign matter, the push-up rod 4 will not be able to descend completely and will protrude from the top surface of the bottom of the mold 2. In addition, a gap is created between the mold 2 and the push-up rod 4. Therefore, if pouring is continued in this state, the molten metal will enter the gap and the bottom of the cast product will become deformed, making it impossible to perform normal casting. be.

Therefore, at the point just before the push-up rod 4 descends (see Figure 1), the push-up rod 4 is pulled out and the area around the hole 3a is cleaned to remove any foreign matter, or the push-up rod 4 is removed with a sledgehammer. The push-up rod 4 is completely lowered by driving it into the hole 3 to ensure normal casting.

By the way, the reality is that the work in this case has traditionally relied entirely on the labor of the workers, who have had to perform this monotonous work at regular intervals in poor environments. The problem was that the burden on the workers was extremely heavy.

This invention was made in view of the above circumstances,
The object of the present invention is to provide a labor-saving device that can automatically pull up and push in a push-up rod.

The apparatus of the present invention is provided with a movable base that follows the movement of the mold of the rotary casting machine on a stand installed above the mold of the rotary casting machine so as to be able to return to its initial position, and the movable base is directed downward. The structure is characterized in that a cylinder mechanism is provided, and a connecting device is provided at the lower end of the rod to connect with the upper end of the push-up rod in the mold.

Hereinafter, the present invention will be specifically explained with reference to the drawings. Figures 5 to 9 show one embodiment of the present invention, with Figure 5 being a plan view showing the overall configuration, and Figure 6 being a plan view showing the overall configuration.
The figure is a side view, and each of FIGS. 7 to 9 is a partially detailed view.

The apparatus of this embodiment is now installed at the continuous anode casting apparatus shown in FIG. 1, and the rotary casting disk 1 is rotating in the direction of arrow A in FIG.

5 and 6, reference numeral 20 in the figure is a pedestal of the apparatus of the present invention, and this pedestal 20 is a rotary casting machine 1.
A trolley 22 that can run on rails 21 laid on the floor is provided so as to be able to appropriately face above the mold 2. On the top surface of this pedestal 20,
An arc-shaped guide rail 23 is provided, and wheels 24 are fitted into the inner groove 23a (see FIGS. 8 and 9) of the guide rail 23, so that the movable platform 25 moves along the arrow mark. , and is movable in the C direction.

In this case, the guide rail 23 has an arcuate curve with a predetermined curvature, and when the pedestal 20 is advanced to a predetermined position above the mold 2 of the rotary casting machine 1, the movable base 25 is slightly different from the rotary casting machine 1. It is designed to be able to move in a circular arc around the center of rotation.

A movable table moving mechanism is provided as means for moving the movable table 25, which is provided above the mold 2 so as to be able to move along the same trajectory as the mold 2.

The movable table mechanism has the following two functions: to move the movable table 25 from the initial position (the position shown in FIG. 5) in the direction of the arrow B in synchronization with the rotation of the rotary casting plate 1; It performs two functions: moving in the direction and returning to the initial position, and in this embodiment, it is divided into two mechanisms according to these two functions.

One is a movable base 25 to perform the above function.
It is a mechanism composed of cylinders 26, 26 attached to the cylinders 26, 26, and positioning rods 27, 27 attached to the rod tips of the cylinders 26, 26,
The other is the mount 20 in order to fulfill the above function.
This mechanism is composed of a cylinder 28 attached to a protruding beam 20a.

First, to explain the former mechanism in detail, the seventh
As shown in FIG. 8, the main bodies of the cylinders 26, 26 are supported by a frame 29 vertically disposed on the movable base 25, and are mounted facing downward. A positioning rod 27 guided by a guide portion 30 is connected to the tip of the rod, and a positioning rod 27 is connected to the tip of the rod.
A block 31 that fits against the inner wall 2b of the mold 2 is attached to the lower end of the mold 7. According to this mechanism, by extending the rods of the cylinders 26, 26 and moving the block 31 into the mold 2 on the rotating casting plate 1, the block 31 is moved as shown in FIG. The movable table 25 collides with the inner wall 2b on the rear side in the rotating direction of the mold 2, and as a result, the movable table 25 moves synchronously with the mold 2 from the initial position (see FIG. 5) in the direction of arrow B in FIG. be. That is, according to this mechanism, by operating the cylinders 26, 26 in a well-timed manner, the movable table 25 can be moved in exactly the same manner as the mold 2 using the rotational power of the rotary casting plate 1.

Next, regarding the latter mechanism, the main body of the cylinder 28 is attached to the protruding beam 20a of the pedestal 20, and the tip of the rod is connected to the movable base 20. The stand 25 can be returned to its initial position.

As mentioned above, by operating the cylinders 26, 26, the position of the movable table 25 with respect to the mold 2 is determined, and the movable table 25 is made to move in accordance with the mold 2, but as shown in FIG. A cylinder 32 for pulling up or pushing the push-up rod is attached to the movable base 25 in a vertically downward direction at a position corresponding to the push-up rod in the mold 2 when the movable table 25 is positioned. ing. in this case,
The cylinder 32 is attached to another frame 33 vertically installed on the movable table 25, so that the rod can be extended and contracted up and down, and the lower end of the rod has a connection that connects with the upper end of the push-up rod 4. A body, that is, an electromagnet 34 in this embodiment, is attached, and the upper end of the push-up rod 4 is configured to be able to be attracted or separated as required.

Although not shown, the apparatus of the above embodiment is further equipped with an automatic brush for cleaning the area around the hole 3a when the push-up rod 4 is pulled up, or a high-pressure air jet nozzle for blowing away foreign matter. The area around the hole 3a can be cleaned completely automatically.

Furthermore, the above-mentioned apparatus is designed to be controlled in a predetermined sequence by, for example, providing a limit switch between it and the rotary casting machine 1 so as to be linked to the operation of the continuous casting apparatus.

Next, the actual operation of the apparatus having the above configuration will be explained. This device operates automatically by the control device as follows.

(1) As the casting disk 1 rotates, the mold 2 sequentially moves below the pedestal 20, and in accordance with this, the limit switch installed between the casting disk 1 and the casting disk 1 operates, and the cylinders 26, 26 operate. The rod is lowered, and the block 31 at the lower end of the positioning rod 27 enters the mold 2 which has reached a predetermined position below the pedestal 20.

(2) This action causes the inner wall 2 of the moving mold 2 to
The side of block 31 hits b, and cylinder 2
Both the movable table 25 to which 6 and 26 are fixed, and the mold 2
move in sync with the movement of.

(3) Shortly thereafter, cylinder 3 is activated by a timer.
2 operates to lower the rod, and the electromagnet 34 approaches the upper end surface of the push-up rod 4 and attracts the push-up rod.

(4) Once the rod is attracted, the rod of the cylinder 32 rises and pulls out the push-up rod 4 from the hole 3 of the mold 2.

(5) In this state, clean the hole 3a using the aforementioned automatic brush or high-pressure air from the air outlet.

(6) When the cleaning is completed, the cylinder 32 is operated by the timer again to lower the rod, insert the push-up rod 4 into the hole 3, and then the rod descends again to push the push-up rod 4 with a strong force. into the hole 3 of the mold 2.

(7) After pushing the push-up rod 4 is completed, the electromagnet 3
4 is released, and the rod of the cylinder 32 rises again. In this case, in order to push the push-up rod 4 more effectively, once the push-up rod 4 is returned to the hole 3 of the mold 2, the adsorption by the electromagnet 34 is released, and the rod of the cylinder 32 The push-up rod 4 may be driven in by a striking operation.

(8) When the push-up rod 4 is finished pushing and the rod of the cylinder 32 rises (it may even be rising), the cylinders 26, 26 that were in position operate, the positioning rod 27 at the lower end of the rod rises, and the block 31 is lifted. Moving away from the mold 2, the synchronization of the movable table 25 is released.

(9) Next, the return movement cylinder 28 is operated to return the movable base 25 to the initial position, completing one cycle of the process, and waiting until the next mold 2 arrives.

In this way, according to the apparatus of the above embodiment, all the conventional manual work is automatically processed while the continuous casting apparatus continues to operate.

In the above embodiment, the mechanism for moving the movable table was constructed separately for the forward and return trips, but any mechanism may be used as long as it can synchronize the movable table with the movement of the mold. By controlling the cylinders 28 in this way, one cylinder 2
It is also possible to provide the robot 8 with a reciprocating function.

Further, in the above embodiment, an electromagnet is used as the connecting body provided at the lower end of the rod of the cylinder 32, but the present invention is not limited to this. Any mechanism may be used as long as it can be easily connected to the push-up rod.

As explained above, according to the present invention, the work of pulling up and pushing in the push-up bar is automatically performed in synchronization with the movement of the mold, which conventionally relies on the labor of the worker. You can take over the work that you were previously doing. Therefore, it greatly contributes to labor saving in the entire casting process.
