Description

Technical Field

[0001] The utility model relates to the technical field of pouring machines, in particular to a speed-adjustable and quantitative pouring machine. Background Technique

[0002] At the present stage, the high-end casting product manufacturing industry is developing towards high-speed automation, and the production processes of parts of high-end products such as automobiles, aviation, and non-ferrous metals are also constantly improving. Due to the complex shape and special material of high-end casting products, their fluidity is poor in the liquid state, so the casting process requirements for casting parts are very high. There are many casting defects in the castings produced by the previous casting process equipment, such as sand inclusion, porosity, looseness and other defects. These casting defects are often found in the final processing process of the parts, wasting the production costs of many links in the meantime.

[0003] Traditional pouring machine equipment and manual pouring cannot achieve automatic speed-adjustable and quantitative pouring. Most rely on manual operation for molten steel pouring. A few rely on traditional pouring machines for molten steel pouring. The adjustable range of pouring speed cannot meet the process requirements of centrifugal casting, and it is difficult to control the weight of the poured molten steel, resulting in ineffective control of casting quality defects, greatly limiting the production efficiency and restricting the development of the industry at the same time.

[0004] Therefore, we propose a speed-adjustable and quantitative pouring machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a speed-adjustable and quantitative pouring machine to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A speed-adjustable and quantitative pouring machine, including a base, on which there are provided a tilting ladle system, an intermediate quantitative ladle system and a pouring spout through which molten steel passes in sequence, and the pouring spout is docked with a centrifuge;

[0007] The tilting ladle system includes a support, inside which there is a tilting ladle, and a tipping shaft is connected between the top of the tilting ladle and the top of the support;

[0008] The intermediate quantitative ladle system includes a weighing system arranged on the base, a rotary support frame is arranged on the weighing system, a quantitative ladle is arranged inside the rotary support frame, and the outer walls on both sides of the quantitative ladle are movably connected with the rotary support frame through a first rotating shaft and a second rotating shaft. The quantitative ladle can be turned along the axial directions of the first rotating shaft and the second rotating shaft. A ladle-turning motor is arranged outside the rotary support frame, and the output shaft of the ladle-turning motor is connected with the first rotating shaft.

[0009] Preferably, two groups of grooves are correspondingly formed on both sides of the top of the rotary support frame. A retaining rod is arranged in each group of grooves. The top of the rotary support frame is also provided with a slidable locking bag connecting rod. When the metering ladle is turned over, the locking bag connecting rod slides and can fix the retaining rod.

[0010] Preferably, the distance between the retaining rods is the same as the length of the metering ladle, and the metering ladle can be fixed.

[0011] Preferably, a coupling is arranged at the end of the first rotating shaft and the output shaft of the ladle turning motor.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: Since the weighing system is lighter in gross weight compared with the molten steel, the weighing value of the molten steel is more accurate (the accuracy can reach 1 Kg). The ladle turning motor is an adjustable-speed motor. At the same time, the moment of inertia of the intermediate metering ladle system is much lower than that of the tilting ladle system, so that the water inlet time is shortened to 2 - 5 s, which is more accurate and faster than the weighing system and the water inlet and ladle turning system of the traditional casting machine. This can fully meet the process requirements of centrifugal casting, effectively improve the casting quality of the castings, reduce the uncontrollable operation links of personnel in the production line, and improve the casting yield.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] Please refer to Figures 1-3 , the present utility model includes a base 1, and an overturning ladle system, an intermediate metering ladle system, and a pouring spout 2 through which molten steel passes in sequence are provided on the base 1. The pouring spout 2 is docked with a centrifuge;

[0020] The overturning ladle system includes a support 3, and a tipping ladle 4 is arranged inside the support 3. A tipping shaft 5 is connected between the top of the tipping ladle 4 and the top of the support 3;

[0021] The intermediate metering ladle system includes a weighing system 6 arranged on the base 1. A rotary support frame 7 is arranged on the weighing system 6. A metering ladle 8 is arranged inside the rotary support frame 7. Rotating shafts one 9 and two 10 are movably connected between the outer walls on both sides of the metering ladle 8 and the rotary support frame 7. The metering ladle 8 can be turned along the axial directions of the rotating shafts one 9 and two 10. A ladle turning motor 11 is arranged outside the rotary support frame 7, and the output shaft of the ladle turning motor 11 is connected to the rotating shaft one 9.

[0022] Specifically, in this embodiment, the tipping ladle 4 is driven by a motor to turn along the tipping shaft 5 to pour the molten steel into the metering ladle 8. At this time, the weighing system 6 starts to work. The weighing system 6 is an electronic scale. After the weight of the poured molten steel reaches the set value, the motor of the tipping ladle 4 stops working. At the same time, the ladle turning motor 11 starts to work. The ladle turning motor 11 is a servo motor and can be speed-regulated to quickly pour the molten steel into the centrifuge to complete the pouring of the molten steel.

[0023] On both sides of the top of the rotary support frame 7, two groups of grooves 12 are correspondingly provided. In each group of grooves 12, a stop bar 13 is provided. On both sides of the top of the rotary support frame 7, a slidable lock bag connecting rod 14 is also provided. When the metering ladle 8 is turned over, the lock bag connecting rod 14 slides and can fix the stop bar 13. The distance between the stop bars 13 is the same as the length of the metering ladle 8, and the metering ladle 8 can be fixed.

[0024] Specifically, in this embodiment, the lock bag connecting rod 14 is spoon-shaped and symmetrically installed on both sides of the top of the rotary support frame 7. When the metering ladle 8 is turned over under the drive of the servo motor, the lock bag connecting rod 14 will slide downward along the side of the rotary support frame 7 and just fix the two stop bars 13 in the grooves 12 to prevent the metering ladle 8 from falling off during the turning process.

[0025] A coupling 15 is provided at the end of the first rotating shaft 9 and connected to the output shaft of the ladle turning motor 11.

[0026] Specifically, in this embodiment, the ends of the first rotating shaft 9 and the second rotating shaft 10 both extend out of the rotary support frame 7. The first rotating shaft 9 and the output shaft of the ladle turning motor 11 are connected by a coupling 15 to ensure high coaxiality of the two shafts, large transmitted torque, and improved work efficiency.

[0027] The working principle of the present utility model:

[0028] First, molten steel is added to the tilting ladle 4. The casting locomotive body is translated to the centrifuge station to be cast. After stopping stably, under the drive of the motor of the tilting ladle system, the tilting ladle 4 is tilted to pour the molten steel into the metering ladle 8. At this time, the weighing system 6 starts to work. After the weight of the molten steel poured into the metering ladle 8 reaches the set value, the motor of the tilting ladle system stops working, and at the same time, the ladle turning motor 11 starts to work. The ladle turning motor 11 can be speed-adjusted and can pour the molten steel into the centrifuge quickly at different speeds to complete the pouring of the molten steel.

[0029] Compared with the molten steel, the weighing system 6 has a lighter gross weight, making the weighing value of the molten steel more accurate (the accuracy can reach 1 Kg). At the same time, the moment of inertia of the intermediate metering ladle system is much lower than that of the tilting ladle system, shortening the water inlet time to 2 - 5 s. It is more accurate and faster than the weighing system and the water inlet ladle turning system of the traditional casting machine, which can fully meet the process requirements of centrifugal casting, effectively improve the casting quality of the casting, and at the same time reduce the uncontrollable operation links of personnel in the production line and improve the casting yield.

[0030] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
