Description

Technical Field

[0001] The utility model relates to the field of refractory brick production, in particular to a refractory brick forming press. Background Art

[0002] In the production process of refractory bricks, the molding process is the most important link. There are many methods for molding refractory bricks. Common molding methods include mechanical pressure molding, vibration molding, melt casting, extrusion molding, ramming molding and other methods. At present, the most commonly used molding method in refractory brick production is machine pressure molding, which uses a brick press and a steel mold to press the mud into a green body.

[0003] After searching, Chinese patent announcement number: CN219054738U discloses an automatic forming refractory brick forging press. By setting a buffer box, the downward pressure stress on the buffer support plate can be buffered to avoid excessive downward impact of the forging plate, which will cause damage to the forging cavity and affect the refractory brick forging effect. By setting a dust removal box, the dust generated during the forging process can be intercepted and purified.

[0004] In the above technical solution, a dust removal box is used to purify the dust generated during forging. However, the dust removal box is in a fixed position for dust removal. However, the smoke and dust will scatter and cannot completely block the forging chamber, which will reduce the purification efficiency. At the same time, the high temperature generated during the forging process is not conducive to the staff to take the refractory bricks, thereby reducing the efficiency of refractory brick forming. For this reason, a refractory brick forming press is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a refractory brick forming press, which aims to improve the problem that the refractory brick forming press in the prior art lacks shielding and dust removal for the forging chamber and is inconvenient for workers to take the formed refractory bricks.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a refractory brick forming press, including a press body, a hydraulic cylinder is fixedly connected to the surface of the press body, a forging plate is fixedly connected to the output end of the hydraulic cylinder, a forging cavity is fixedly connected to the surface of the press body, the press body is provided with a protective structure, the protective structure includes a receiving plate, a steel wire rope is fixedly connected to the outer wall of the receiving plate, a fixing ring is fixedly connected to the outer wall of the forging cavity, the end of the steel wire rope is fixedly connected to a circular shell, a protective component is provided on the surface of the press body, and a fixing component is provided on the surface of the forging cavity.

[0007] As a further description of the above technical solution:

[0008] A connecting groove is provided on the surface of the press body, a buffer block is fixedly connected to the inner wall of the connecting groove, and a following block is fixedly connected to the outer wall of the circular shell.

[0009] As a further description of the above technical solution:

[0010] The lower surface of the buffer block is arranged in an inclined shape.

[0011] The utility model has the following beneficial effects:

[0012] 1. In the utility model, an air pump is provided to draw air into the inner part of the circular shell. The suction force of the air causes the smoke and high-temperature gas generated during forging to be drawn out through the through hole and introduced into the external water tank. The separation of the fixed column and the threaded hole causes the receiving plate to be out of position. The weight of the circular shell will gradually slide down in the groove. The pulling force of the wire rope causes the receiving plate to drive the refractory bricks out of the forging cavity, thereby facilitating the workers to take them, reducing the smoke in the refractory brick forming process, and accelerating the air flow to reduce the surface temperature of the refractory bricks, thereby improving the efficiency of refractory brick forming.

[0013] 2. In the present invention, the impact of the downward movement of the circular shell can be reduced by the cooperation of the buffer block and the follower block, and the upward resistance of the circular shell is relatively small, thereby ensuring the stability of the refractory bricks driven by the receiving plate while ensuring that the circular shell performs protective operations during forging.

Four groups of steel wire ropes 6 are arranged, and the four groups of steel wire ropes 6 are distributed in a rectangular array with the center point of the receiving plate 5 as the symmetry axis. The steel wire ropes 6 penetrate into the inner wall of the forging cavity 4. The outer wall of the forging cavity 4 is fixedly connected with a fixing ring 7. The fixing ring 7 provides a limiting function for the steel wire rope 6, and the number of the fixing rings is equal to the number of the steel wire ropes 6. The end of the steel wire rope 6 is fixedly connected with a circular shell 8. The interior of the circular shell 8 is arranged in a cavity. The surface of the press body 1 is provided with a protective component, and the surface of the forging cavity 4 is provided with a fixing component.

[0022] Reference Figure 2-Figure 4 The outer wall of the receiving plate 5 is adapted to the inner wall of the forging cavity 4, the fixing ring 7 is sleeved on the outer wall of the wire rope 6, the protective component includes a groove 9, a through hole 10 is opened on the inner surface of the circular shell 8, and a connecting hose 11 is fixedly connected to the inner wall of the circular shell 8. A section of the connecting hose 11 near the air pump 12 is retractable, and the port of the connecting hose 11 is fixed with the air pump 12. The fixing component includes a threaded hole 13, and the inner wall of the threaded hole 13 is threadedly connected with a fixing column 14. When the bottom of the receiving plate 5 is at the lowest end inside the forging cavity 4, the fixing column 14 can be connected to the threaded hole 13. The groove 9 is opened on the surface of the press body 1, and the inner wall of the groove 9 is adapted to the outer wall of the circular shell 8. The groove 9 can facilitate the embedding and placement of the circular shell 8. The outer wall of the air pump 12 is fixedly connected to the outer wall of the press body 1, and the threaded hole 13 is opened on the outer wall of the receiving plate 5. The outer wall of the fixing column 14 is threadedly connected to the inner wall of the forging cavity 4.

[0023] Reference Figure 3-Figure 4A connecting groove 15 is provided on the surface of the press body 1, and the connecting groove 15 is connected to the groove 9. A buffer block 16 is fixedly connected to the inner wall of the connecting groove 15. Several groups of buffer blocks 16 are provided, and the several groups of buffer blocks 16 are mirror-imaged in pairs with the central axis of the connecting groove 15 as the symmetry axis. The buffer blocks 16 are made of rubber material. A follower block 17 is fixedly connected to the outer wall of the circular shell 8. The lower surface of the buffer block 16 is inclined, and the bottom of the buffer block 16 is inclined so that the resistance of the follower block 17 when it descends is greater than the resistance of the follower block 17 when it rises.

[0024] Working principle: The hydraulic cylinder 2 is used to drive the forging plate 3 to descend to the inside of the forging chamber 4 to forge the refractory bricks. During the forging process, high temperature and smoke are generated. The filter of the air pump 12 is introduced into the external water tank through a hose. The air pump 12 is started to extract the air inside the circular shell 8 through the connecting hose 11. The suction force of the air will allow the smoke and high-temperature gas to enter the inside of the circular shell 8 through the through hole 10, and then enter the external water tank through the filter of the air pump 12. When the forging plate 3 rises away from the forging chamber 4, the operator reverses the fixed column 14 to gradually disengage it. From the threaded hole 13, at this time, since the receiving plate 5 is out of position, the weight of the circular shell body 8 is heavier than the receiving plate 5, and the circular shell body 8 descends through the wire rope 6 so that the receiving plate 5 drives the refractory bricks to rise inside the forging cavity 4. At the same time, the following blocks 17 will contact with the buffer blocks 16 in groups of two. The buffer blocks 16 provide a certain resistance to the following blocks 17 to prevent the circular shell body 8 from descending too fast. When the circular shell body 8 completely falls into the interior of the groove 9, the receiving plate 5 is in the upper end area of ​​the forging cavity 4, which is convenient for the staff to take it and improves the efficiency of refractory brick forging.
