Problems solved by technology

[0002] In the field of metallurgical casting, in order to improve production efficiency, a continuous casting line has gradually been formed. The casting line is a production line for continuous casting. Multiple casting sand boxes pass through the conveying device sequentially under the molten iron ladle, and the molten iron is injected. During the process of changing the sand box, the molten iron overflows into the next sand box, resulting in poor quality of the casting product. The problem with this method is that the stopper repeatedly contacts and leaves the molten iron, which often occurs when the molten iron attached to the surface of the stopper solidifies and sticks to the surface of the stopper, causing the stopper to lose its function, opening and closing insensitive, and in severe cases There are too many attachments on the block, which still prevents the overflow of molten iron in the open state, causing the danger of molten iron hurting people

specific Embodiment approach 1

[0061] combine figure 1 and figure 2 As shown, a graphite lubricating device for metallurgical casting blocks disclosed in this embodiment includes: a frame 1, a lifting mechanism 2, an ink spreading mechanism 3 and a block turning mechanism 4, and the upper end of the frame 1 is fixed to the wall End connection, the frame 1 is provided with a lifting mechanism 2, the lifting end of the lifting mechanism 2 is fixedly connected with the ink spreading mechanism 3, a stopper 5 is set under the ink spreading mechanism 3, and the side of the stopper 5 is connected with the stopper turning mechanism 4 , the block turning mechanism 4 is fixedly connected with the frame 1;

[0062] When the stopper 5 is blocked, the lifting mechanism 2 drives the stopper 5 to move downward, while the stopper turning mechanism 4 makes the stopper 5 turn over while moving downwards, and the ink spraying mechanism 3 is on the outside of the stopper 5 in the process of turning over. Ink is sprinkled on...

specific Embodiment approach 2

[0072] This implementation mode is based on the specific implementation mode 1, combining Figure 5 As shown, the difference is that the top of the fixed ink cartridge 31 or the vibrating ink cartridge 32 is hinged with an ink cartridge cover.

[0073] As the vibrating cartridge undergoes repeated vibrations, the graphite powder is splashed by implementing the cartridge cover.

specific Embodiment approach 3

[0074] This implementation mode is based on the specific implementation mode 1, combining figure 1 and image 3 As shown, the difference is that the transmission gear 38 is internally sleeved with a one-way bearing 39, the outer ring of the one-way bearing 39 is fixedly connected with the transmission gear 38, and the inner ring of the one-way bearing 39 is fixedly connected with the vibrating cartridge vibration block B37 , the anti-rotation direction of the one-way bearing 39 is counterclockwise;

[0075] When the stopper 5 moves upwards, there is no need to spray ink. At this time, the auxiliary gear 381 rotates counterclockwise, which drives the transmission gear 38 to rotate clockwise. The one-way bearing 39 allows rotation in the clockwise direction, and the vibration of the ink cartridge vibration block B37 does not occur. Rotate, the vibrating ink cartridge stops vibrating, and the ink spreading mechanism stops ink spraying, which realizes that ink spraying is not per...

Abstract

The invention relates to the technical field of metallurgical casting, in particular to a graphite-spraying type adhesion prevention method for a casting stop piece. The graphite-spraying type adhesion prevention method comprises a frame, a lifting mechanism, a graphite spraying mechanism and a stop piece rollover mechanism; the upper end of the frame is connected with a fixed end of a wall body;the lifting mechanism is arranged on the frame; a lifting end of the lifting mechanism is fixedly connected with the graphite spraying mechanism; the stop piece is arranged below the graphite sprayingmechanism; the side surface of the stop piece is connected with the stop piece rollover mechanism; the stop piece rollover mechanism is fixedly connected with the frame; the cylindrical stop piece can move up and down and can be rolled over in motion; moreover, the surface of the stop piece is coated with a graphite powder layer when the stop piece is rolled over so that a contact surface of thestop piece and molten iron is covered by one graphite powder layer; the contact surface of the stop piece and the molten iron is totally covered by the graphite powder sprayed layer, and thus the problem that the surface of the casting stop piece is adhered with the molten iron in a metallurgical casting is solved.
