Description

TECHNICAL FIELD The present invention relates to a metal frame inner surface coating type coating apparatus, and more particularly to a metal frame inner surface coating type coating apparatus in centrifugal casting.

[Prior Art] When centrifugal casting is performed using a mold, a coating type is applied to the inner surface of the metal frame as a heat insulating treatment. Particularly, when the coating type is applied to the inner surface of a small diameter metal frame, a coating pipe (lance pipe) is used. ) Comes into contact with the inner surface of the metal frame, and the coating mold peels off. Further, since the coating of the coating mold is performed by rotating the metal frame, an accident may occur due to damage of the lance pipe or the coating cart falling over.

The contact of the lance pipe occurs due to the small diameter of the metal frame, but the lance pipe vibrates and makes contact when the coating carriage travels in the axial direction of the metal frame.

[Problems to be Solved by the Invention] In the present invention, in view of the problems in applying the coating mold to the inner surface of the conventional metal frame described above, the present inventors have conducted diligent research, and as a result of repeated studies, Even with a small-diameter metal frame,
Since the lance pipe does not vibrate or swing, there is no peeling of the coating mold applied to the inner surface of the metal frame, and it is possible to apply the coating mold to the inner surface of the metal frame stably. The mold coating device was developed.

[Means for Solving the Problems] A feature of the metal frame inner surface coating type coating apparatus according to the present invention is that a lance pipe that has a coating nozzle at the tip and is connected to the coating type supplying apparatus is a metal frame. Is supported by a wire penetrating in the axial direction so that the inner surface of the metal frame can be moved in the axial direction of the metal frame and the tip of the lance pipe does not vibrate or swing.

The metal frame inner surface coating type coating apparatus according to the present invention will be described in detail below with reference to the example shown in FIG.

That is, referring to FIG. 1, the metal frame 1 is placed on the casting metal frame rotating roller 8 provided on the base 12, the inner surface of the metal frame 1 has the coating nozzle 11 at the tip, and the other end is the coating cart. The lance pipe 2 fixed to the front part of 3 and further provided with the coating type supply hose 10 communicating with the coating nozzle 11, and the wire 5 axially penetrating the metal frame at its inner upper end is inserted. Then, it is supported by the wire 5. One end of the wire 5 is fixed to a clamp 6 fixed to the level adjuster 7, and the other end is wound around a tension reel 4 provided at the rear part of the coating cart 3 to apply tension. In addition, 9 is a traveling rail of the coating cart. Further, the lance pipe 2 may be a stretchable pipe.

A metal frame inner surface coating type coating apparatus according to the present invention is provided with a lance pipe 2.
In order to prevent the contact with the inner surface of the metal frame 1 due to the vibration of the wire 5, the wire 5 is used as a guide and the lance pipe 2 is run along the wire 5. Move it up and set the lance pipe 2 to the gold frame 1.
Since the wire 5 inserted in the lance pipe 2 is attached to the clamp 6, the coating nozzle 11 at the tip of the lance pipe 2 is positioned along the wire 5 at the coating type coating start point of the metal frame 1. To

Then, at the same time when the rotation of the metal frame 1 is started, the coating cart 3 is moved to the arrow A.
The coating mold is sprayed from the coating mold supply hose 10 from the coating nozzle 11 while maintaining the tension of the wire 5 to start coating.

In this case, the lance pipe 2 is the wire 5 which is the copying guide.
Since there is no contact between the tip of the lance pipe 2 and the inner surface of the metal frame 1 due to vibration or rocking,
Since the lance pipe 2 is always kept constant by adjusting the level adjuster 7 to a level at which the inner surface of the metal frame 1 and the tip of the lance pipe 2 do not contact each other, the lance pipe 2 contacts the inner surface of the metal frame 1 of the lance pipe 2. Therefore, the applied coating film is not peeled off, the lance pipe 2 is not damaged, and the accident caused by the overturning of the coating carriage 3 is also eliminated.

[Effects of the Invention] As described above, since the metal frame inner surface coating type coating apparatus according to the present invention is configured as described above, it is possible to coat the inner surface of the metal frame of the continuous casting apparatus having a small diameter, and the vibration or shaking. Since the occurrence of movement can be prevented, a stable surface can be obtained as the coating surface of the coating type, and further, the occurrence of accidents in the coating process can be prevented, which is an excellent effect.
