Description

Technical Field

[0001] The present invention relates to the field of casting technology, and more specifically, to a casting quality monitoring device. Background Art

[0002] In the manufacturing process of castings, casting is a crucial step, which directly affects the microstructure, mechanical properties, and subsequent processing and application of the castings. There are some shortcomings in the traditional control method of aluminum castings, which are mainly manifested in the following aspects: the purity of the molten aluminum: the refining process lacks real-time and effective monitoring, the temperature loss of the molten aluminum during the process, insufficient refining, incomplete impurity removal, etc., resulting in the molten aluminum not meeting the casting process requirements, causing slag inclusions and other poor molding, as well as problems such as substandard composition and organizational performance; the filling integrity problem: the molten aluminum temperature, mold structure, temperature field setting, etc., affect the filling efficiency and shrinkage compensation of the molten aluminum, and are prone to filling defects, shrinkage and other problems; the cooling uniformity problem: during the cooling process of aluminum castings, due to differences in the geometry, wall thickness, distribution of cooling media and other factors in different areas of the casting, the cooling is uneven. Inconsistent speeds can easily lead to uneven cooling, which may cause stress concentration and deformation inside the casting, affecting the quality and performance of the casting; Casting efficiency issues: Traditional casting control methods may result in low cooling efficiency due to inaccurate temperature control of molten aluminum and cooling media, unreasonable layout of cooling equipment, etc., which prolongs the production cycle and increases energy consumption and production costs; Insufficient monitoring of the casting process: In some existing casting control systems, the monitoring of the process is not comprehensive and accurate enough, and there is a lack of real-time and effective temperature monitoring, flow detection, composition detection and other detection methods and data analysis methods, making it difficult to promptly detect and deal with abnormal situations in the casting process.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] As attached Figure 1 -Attached Figure 3 As shown, a casting quality monitoring device includes a coolant temperature monitoring mechanism, a refining monitoring mechanism, a raw material detection mechanism, and a data analysis mechanism, and the data analysis mechanism is electrically connected to the coolant temperature monitoring mechanism, the refining monitoring mechanism, and the raw material detection mechanism respectively.

[0022] The coolant temperature monitoring mechanism includes a cooling jacket 2 arranged outside the mold 1, and the two ends of the cooling jacket 2 are respectively connected to a liquid inlet pipe 5 and a liquid outlet pipe 7, the end of the liquid inlet pipe 5 away from the cooling jacket 2 is connected to a buffer 4, the end of the buffer 4 away from the liquid inlet pipe 5 is connected to a liquid supply pipe 3, the buffer 4 is provided with a temperature measuring mechanism 6, and the liquid outlet pipe 7 is provided with a temperature sensor 33, the buffer 4 includes an expanding section 8, a detection section 9, a reducing section 10 and a reducing section 11 connected in sequence, the diameter of the end of the expanding section 8 connected to the liquid supply pipe 3 is smaller than the diameter of the end connected to the detection section 9, the diameter of the end of the reducing section 10 connected to the detection section 9 is larger than the diameter of the end connected to the reducing section 11, and the diameter of the end of the reducing section 11 connected to the reducing section 10 is smaller than the diameter of the end connected to the liquid inlet pipe 5. By setting the diameters of the expansion section 8, the detection section 9, the reduction section 10 and the reduction section 11, the flow rate of the coolant supplied from the liquid supply pipe 3 is slowed down before entering the liquid inlet pipe 5, and the residence time of the coolant in the buffer 4 is prolonged, so that the temperature measuring mechanism 6 can be more fully in contact with the coolant, so that the temperature of the coolant can be more accurately detected. Accurate data is provided for the subsequent temperature change of the coolant, so that the cooling rate of the casting can be correctly detected, ensuring that the casting is cooled normally, the internal stress of the casting is effectively released, and deformation and cracks are avoided.

[0023] The connection between the liquid supply pipe 3 and the expanded diameter section 8 is located below the center line of the detection section 9, and the connection between the reduced diameter section 11 and the reduced diameter section 10 is located above the center line of the detection section 9. An arc plate 12 is arranged above the detection section 9, and the middle position of the arc plate 12 bulges upward. A mounting hole 15 is provided in the middle position of the arc plate 12, and a sealing plug 16 is arranged in the mounting hole 15. The temperature measuring mechanism 6 includes a mounting seat 14 installed on the upper part of the arc plate 12, and a temperature sensor 1 17 and a temperature sensor 2 18 are installed at the lower part of the mounting seat 14. The temperature sensor 1 17 and the temperature sensor 2 18 are arranged through the sealing plug 16, and the length of the temperature sensor 1 17 is less than the length of the temperature sensor 2 18. The bottom end of the temperature sensor 1 17 is close to the center line of the detection section 9, and the bottom end of the temperature sensor 2 18 is close to the bottom of the detection section 9.

[0024] The temperature sensor 1 17 and the temperature sensor 2 18 are provided to detect the coolant temperature respectively, so that the two detection results can be compared and the data with large difference between the two can be eliminated, so as to ensure the accuracy of the detection result.

[0025] The bottom end of the temperature sensor 2 18 is close to the bottom of the detection section 9, and is mainly aimed at the temperature of the coolant that directly enters the detection section 9 from the liquid supply pipe 3. After passing through the temperature sensor 2 18, the coolant contacts the inner side of the lower side wall of the reduced diameter section 10, and rises along the inner side of the inclined lower side wall of the reduced diameter section 10. Since the diameter of the connection between the reducing section 11 and the reducing section 10 is small, part of the coolant cannot pass directly, and will flow back along the upper side wall of the reducing section 10, the top of the detection section 9, and the upper side wall of the expanding section 8. The refluxed coolant merges with the coolant entering from the liquid supply pipe 3. Due to the different flow directions, the two impact each other and slow down the flow rate. The merged coolant flows to the connection between the reducing section 11 and the reducing section 10. These coolants will pass through the temperature sensor 17, and the temperature sensor 17 will monitor the temperature of these coolants.

[0026] Temperature sensor 1 17 and temperature sensor 2 18 monitor different coolants and can obtain more data for comparison.

[0027] A mounting block 19 is installed on the outer periphery of the upper side wall of the expanded diameter section 8, and a guide plate 20 is inserted into the mounting block 19. The guide plate 20 is arc-shaped. A hole with the same arc as the guide plate 20 is opened on the side wall of the expanded diameter section 8 and the mounting block 19, so that the guide plate 20 can extend into the expanded diameter section 8 through the hole, and the guide plate 20 can move along the hole.

[0028] The guide plate 20 can guide the coolant that has just entered the expanded diameter section 8 of the liquid supply pipe 3 so that the coolant flows downward. Secondly, the guide plate 20 guides the refluxed coolant so that the refluxed coolant flows to the lower end of the temperature sensor 1 17. In this way, the coolant detected by the temperature sensor 1 17 and the temperature sensor 2 18 can be better distinguished, thereby making the detection data more diverse.

[0029] One end of the guide plate 20 located outside the mounting block 19 is connected to a limiting block 21, and the limiting block 21 is used to limit the guide plate 20 to prevent the guide plate 20 from falling into the buffer 4.

[0030] A speed reduction mechanism 13 is installed in the lower side wall of the reduced diameter section 10, and the speed reduction mechanism 13 can actively operate to slow down the flow rate of the coolant in the buffer 4. A through hole 1 22 and a through hole 2 23 are provided in the lower side wall of the reduced diameter section 10, and the through hole 1 22 and the through hole 2 23 are connected. The through hole 1 22 is connected to the inner side of the side wall of the reduced diameter section 10, and the through hole 2 23 is connected to the outer side of the side wall of the reduced diameter section 10. A step surface 24 is formed between the through hole 1 22 and the through hole 2 23. The speed reduction mechanism 13 includes a motor seat 27 installed in the through hole 23, and the outer periphery of the motor seat 27 is against the inner wall of the through hole 23. A motor 30 is installed on the side of the motor seat 27 away from the through hole 1 22. The motor 30 is driven and connected to the fan blade 31, and the fan blade 31 is located on the side of the motor seat 27 close to the through hole 1 22. The motor 30 drives the fan blades 31 to rotate, which can stir the coolant and make the coolant have a movement trend from right to left, which is opposite to the movement trend of the coolant entering from the liquid supply pipe 3, so that the coolant can produce a significant deceleration effect.

[0031] A fixing plate 32 is also installed at the second through hole 23. The fixing plate 32 has two parts. One part is located in the second through hole 23 and abuts against the motor 30, and the other part is fixed to the outer side of the side wall of the reduced diameter section 10 by bolts to seal the second through hole 23.

[0032] A sealing ring 25 is arranged in the through hole 1 22 , a part of the sealing ring 25 is located in the through hole 1 22 and is arranged in contact with the inner wall of the through hole 1 22 , a part of the sealing ring 25 is located on the step surface 24 and is arranged in contact with the step surface 24 , and the sealing ring 25 plays a sealing role.

[0033] An adjustment plate 26 is detachably mounted on the motor seat 27, and a hole is opened in the middle of the adjustment plate 26. The adjustment plate 26 is mounted on the motor seat 27. A slot 28 is opened on the side of the motor seat 27 facing the through hole 1 22, and an insert block 29 is connected to the adjustment plate 26 to match the slot 28 and can be inserted into the slot 28. Adjustment plates 26 with different apertures can be installed on the motor seat 27 to control the strength of stirring the coolant when the fan blades 31 rotate, thereby producing different degrees of deceleration.

[0034] The refining monitoring mechanism is used to obtain the refining furnace related data and send it to the data analysis mechanism. The refining furnace related data at least includes: real-time refining furnace temperature, atmosphere, stirring intensity parameters, and gas escape data during the refining process. The exhaust gas data at least includes: SO2 concentration, NOX concentration and dust content.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
