Description

Technical Field

[0001] This invention relates to the field of heating furnace processing technology, and in particular to a prefabricated slide rail brick forming machine for heating furnaces. Background Technology

[0002] Heating furnaces, as key thermal energy equipment in metallurgy, machining, chemical industry, and power industry, generate heat through fuel combustion or electrical energy conversion to heat materials, workpieces, or media. Slide rail bricks, as the core refractory material product of the furnace bottom, are mainly used to support the smooth sliding of materials such as steel billets during heating. Their quality and forming efficiency directly affect the operational stability and production efficiency of the heating furnace.

[0003] For example, Chinese patent document CN104162926B discloses a brick forming machine. This machine includes a frame, a vibration platform mechanism, a mold frame, a press head, a press head connector, a connecting plate, a press head drive mechanism, and a sleeve. By fitting a vertically movable sleeve around the press head connector, with the outer wall of the sleeve aligned with the outer wall of the press head, the material remaining at the chamfer of the mold frame and on the mold frame ribs during pressing will not fall onto the press head and press head connector during vibration and demolding. This prevents the material from mixing with the secondary pressing material and thus avoids substandard product quality.

[0004] While the aforementioned molding machine can perform basic brick-making and pressing functions, it requires manual labor to pour raw materials into the mold. After the raw materials are pressed into shape, workers still need to manually remove the sliding track bricks. The entire production process relies on manual participation. This not only leads to low production efficiency, making it difficult to meet the needs of large-scale production, but also may affect the molding accuracy and quality stability of the sliding track bricks due to differences in manual operation, while increasing labor costs and operational safety risks.

In terms of cost and safety: Fully automated operation significantly reduces labor costs and safety risks associated with manual operation. All components are linked by mechanical structures such as gears and synchronous pulleys, resulting in efficient and reliable power transmission, which reduces equipment operating energy consumption and maintenance costs. At the same time, the guide plate ensures that finished bricks are discharged in an orderly manner, facilitating subsequent transfer and processing, and improving the continuity of the overall production process.

Through the cooperation of the first servo motor 3, the rotating rod 4, and the extrusion assembly, the machine extrudes and forms the slide rail bricks; through the cooperation of the first servo motor 3, the rotating rod 4, and the material ejection assembly, the machine ejects the formed slide rail bricks from the forming groove; a pushing assembly installed on the fixed frame 1 and the rotating rod 4, through the cooperation of the first servo motor 3, the rotating rod 4, and the pushing assembly, the machine discharges the slide rail bricks from the worktable 5; and a feeding assembly and a powder spraying assembly installed on the rear side of the fixed frame 1.

[0021] Furthermore, the extrusion assembly includes a pressure plate 22, a second telescopic rod 23, a second wheel frame 24, a second roller 25, a second spring 26, and a second convex plate 27. The second telescopic rod 23 is slidably mounted on the disc 6. The pressure plate 22 is fixedly mounted on the bottom end of the second telescopic rod 23.

The second spring 26 is sleeved on the outer wall of the second telescopic rod 23 and is located between the disc 6 and the second wheel frame 24. The second convex plate 27 is fixedly mounted on the top of the fixed frame 1. The second roller 25 and the second convex plate 27 are connected. When the plates 27 come into contact, the first servo motor 3 is started, and its output shaft drives the rotating rod 4 to rotate. The rotating rod 4 synchronously drives the worktable 5, the disc 6 and related components mounted on them to rotate. When the forming trough loaded with raw materials rotates with the worktable 5 to the extrusion station, the second roller 25 on the disc 6 comes into contact with the second convex plate 27 on the top of the fixed frame 1. The second convex plate 27 presses down on the second telescopic rod 23 through the second roller 25 and the second wheel frame 24, and compresses the second spring 26.

[0022] Furthermore, the top material assembly includes a discharge plate 16, a first telescopic rod 17, a first wheel frame 18, a first roller 19, a first spring 20, and a first convex plate 21.

After the formed brick blank is ejected from the forming groove, the rotating rod 4 rotates, driving the second gear 31 on the outer wall to rotate. The second gear 31 meshes with the first gear 30 on the rotating rod 28, thereby driving the rotating rod 28 and the bending plate 29 to rotate. The bending plate 29 pushes the brick blank ejected to the surface of the worktable 5 onto the front guide plate 32. The brick blank is discharged in an orderly manner along the guide plate 32.

The second spiral blade 13 is in contact with the inner wall of the raw material box 7, so that the raw material can be accurately and quantitatively supplied.

[0025] Furthermore, the powder-spraying assembly includes a dry ash box 8, a first rotating shaft 10, and a first spiral blade 11. The dry ash box 8 is fixedly installed on the rear side of the fixing frame 1. The first rotating shaft 10 is rotatably installed on the front and rear sides of the dry ash box 8. The first spiral blade 11 is fixedly installed on the outer wall of the first rotating shaft 10 and contacts the inner wall of the dry ash box 8. When the second servo motor 9 is started, its output shaft drives the first rotating shaft 10 and the first spiral blade 11 on the outer wall to rotate. The first spiral blade 11 accurately and quantitatively conveys the dry ash in the dry ash box 8 to the forming groove of the workbench 5 through the dry ash port, preparing for subsequent anti-sticking during forming. The first synchronous wheel 14 on the first rotating shaft 10 drives the second synchronous wheel 15 and the second rotating shaft 12 to rotate through the synchronous belt 33. The second spiral blade 13 on the outer wall of the second rotating shaft 12 quantitatively conveys the raw material in the raw material box 7 to the forming groove that has been covered with dry ash through the raw material port.

[0026] Furthermore, a second servo motor 9 is fixedly installed on the front outer wall of the dry ash box 8. The output shaft of the second servo motor 9 is fixedly installed on one end of the first rotating shaft 10. A first synchronous pulley 14 is fixedly installed on the outer wall of the first rotating shaft 10. A second synchronous pulley 15 is fixedly installed on the outer wall of the second rotating shaft 12. A synchronous belt 33 is sleeved on the outer walls of the first synchronous pulley 14 and the second synchronous pulley 15. The synchronous belt 33 meshes with the first synchronous pulley 14 and the second synchronous pulley 15.

[0027] Furthermore, the bottom of the raw material box 7 is provided with a raw material outlet, and the bottom of the dry ash box 8 is provided with a dry ash outlet. Both the raw material outlet and the dry ash outlet are in contact with the top of the workbench 5.

[0028] Furthermore, the thread pitch of the second spiral blade 13 is greater than the thread pitch of the first spiral blade 11.

[0029] Furthermore, a guide plate 32 is provided on the front side of the workbench 5, and the bottom of the guide plate 32 is fixedly installed with the bottom of the fixed frame 1.

[0030] Working principle: First, the brick-making raw materials are put into the raw material box 7, and the dry ash (anti-sticking material) is put into the dry ash box 8. The second servo motor 9 is started, and its output shaft drives the first rotating shaft 10 and the first spiral blade 11 on the outer wall to rotate. The first spiral blade 11 accurately and quantitatively conveys the dry ash in the dry ash box 8 to the forming groove of the workbench 5 through the dry ash port, preparing for subsequent anti-sticking molding. At the same time, the first synchronous pulley 14 on the first rotating shaft 10 drives the second synchronous pulley 15 and the second rotating shaft 12 to rotate through the synchronous belt 33. The second spiral blade 13 of the wall has a larger thread pitch than the first spiral blade. Adapting to the raw material supply, it quantitatively delivers the raw material from the raw material box 7 through the raw material inlet to the forming trough that has been covered with dry ash. Then, the first servo motor 3 is started, and its output shaft drives the rotating rod 4 to rotate. The rotating rod 4 synchronously drives the worktable 5, the disc 6, and related components mounted on them to rotate. When the forming trough loaded with raw material rotates with the worktable 5 to the extrusion station, the second roller 25 on the disc 6 contacts the second protruding plate 27 on the top of the fixed frame 1. The second protruding plate 27 passes through the second... Roller 25 and second wheel frame 24 press down on second telescopic rod 23 and compress second spring 26. Pressure plate 22 at the bottom of second telescopic rod 23 moves downward accordingly, applying uniform extrusion pressure to the raw material in the forming groove to complete the extrusion forming of slide rail brick blank. After forming, worktable 5 continues to rotate with rotating rod 4 to the top material station. At this time, first roller 19 at the bottom of first telescopic rod 17 at the bottom of forming groove contacts first convex plate 21 at the bottom of fixed frame 1. First convex plate 21 pushes first telescopic rod 23 upward through first roller 19 and first wheel frame 18. The first telescopic rod 17 stretches the first spring 20, and the discharge plate 16 at the top of the first telescopic rod 17 pushes the formed brick blank out of the forming groove. At the same time, when the rotating rod 4 rotates, it drives the second gear 31 on the outer wall to rotate. The second gear 31 meshes with the first gear 30 on the rotating rod 28, thereby driving the rotating rod 28 and the bending plate 29 to rotate. The bending plate 29 pushes the brick blank that has been pushed out to the surface of the worktable 5 onto the guide plate 32 on the front side. The brick blank is discharged in an orderly manner along the guide plate 32, completing the entire automated process of "feeding - powdering - extrusion molding - ejection - discharge". No manual intervention is required for raw material feeding and brick blank handling throughout the process.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
