Description

Technical Field

[0001] The invention relates to the technical field of metal heat treatment, in particular to a solid solution aging furnace capable of continuously producing aluminum alloy heat treatment. Background Art

[0002] The heating principles of the solution furnace and the aging furnace are basically the same. They both use heating elements to convert electrical energy or thermal energy into heat to increase the temperature inside the furnace, and cooperate with the cooling mechanism to heat treat the metal material. The continuous solution aging furnace mostly uses a rod conveying mechanism to continuously convey the workpiece or the support for placing the workpiece;

[0003] The utility model with the existing publication number CN219079592U provides a fully automatic elevated solid solution furnace roller aging furnace production line, which mainly includes a solid solution furnace unit, an aging furnace unit, and a conveying unit. A conveying mechanism is added between the solid solution furnace and the aging furnace, which organically combines the two originally unrelated furnace bodies to form a production line; the hardness and strength of the alloy material are fully automated, and it is a fully automatic production line that uses a chain belt loading frame to pass through the furnace for transportation. The above scheme continuously produces the workpieces treated with solid solution and aged by the roller conveying structure. During production and processing, aluminum alloy workpieces need to be quickly cooled down after being treated in the solution furnace and the aging furnace. For example, the aluminum alloy workpiece is heated to the required temperature in the solution furnace. After being taken out of the furnace, the heated workpiece and the frame need to be sent underwater for cooling through a lifting mechanism. After cooling, they are continuously transported to the aging furnace through a roller conveyor mechanism for reheating and aging treatment. The cooling medium in the cooling pool will affect the cooling efficiency of the workpiece after continuous and long-term use, thereby requiring the aging treatment to be extended. In addition, the cooling medium is easily contaminated, which in turn affects the surface quality of the workpiece after cooling. Summary of the Invention

[0038] Embodiment 1: A solution aging furnace for continuous production of aluminum alloy heat treatment comprises a heat treatment furnace 1, wherein the heat treatment furnace 1 is horizontally arranged on the ground, and a lifting control frame 2 is provided on the side close to the heat treatment furnace 1, and a lifting roller frame 3 is provided in the lifting control frame 2 for lifting.

The lower end of the lifting roller frame 3 is provided with two supporting beams. The plurality of bearing boxes 5 are respectively fixed on the upper ends of the two supporting beams. Bearing grooves are opened through the support rollers 6. Bearing rods 7 are provided at both ends of the support rollers 6. The two bearing rods 7 respectively pass through the bearing box 5 and are inserted into the bearing grooves. The bearing rods 7 are located in the bearing grooves and are sleeved with two bearings. The support roller 6 is rotated and provided below the lifting roller frame 3. When the plurality of support rollers 6 need to be actively rotated, they can be coordinated and controlled through the existing sprockets and chains.

[0040] Disc grooves are provided on both sides of the bearing groove of the bearing box 5, and a first annular clamping plate 8 is provided on the side of the disc groove close to the bearing through threaded insertion, and two sealing rubber rings 9 are respectively inserted into the inner circumference of the first annular clamping plate 8, and a second annular clamping plate 10 is provided on the side of the disc groove away from the bearing, and one side of the second annular clamping plate 10 is in tight contact with the first annular clamping plate 8 and the sealing rubber ring 9. The inner circumference of the sealing rubber ring 9 elastically fits the bearing rod 7 of the support roller 6, and the inner diameter of the second annular clamping plate 10 is larger than the diameter of the bearing rod 7. An annular diverter groove 11 is provided in the bearing groove of the bearing box 5 and between the two bearings, and a first annular matching groove 12 is provided on one side of the disc groove, and a first annular matching groove 12 is provided between the annular diverter groove 11. There are several first ventilation grooves 14, and the first annular clamping plate 8 is provided with a second annular matching groove 13 on the side close to the first annular matching groove 12. The sealing rubber ring 9 is close to the inner peripheral side of the bearing rod 7 and is provided with a drainage chute 18 away from the bearing. A transfer annular groove 16 is provided on the side close to the drainage chute 18 in the sealing rubber ring 9. Several second ventilation grooves 15 are provided in the first annular clamping plate 8 and the sealing rubber ring 9 to connect with the second annular matching groove 13 and the transfer annular groove 16, and several ejection holes 17 are provided in the transfer annular groove 16 to connect with the drainage chute 18. When the bearing box 5 and the support roller 6 enter the cooling water of the cooling water pool 4, external water can be prevented from entering the bearing box 5, thereby improving the rotation stability of the bearing and the support roller 6.

[0041] After the lifting roller frame 3 and the upper workpiece enter the cooling water of the cooling water pool 4, an enhanced cooling component is set to perform enhanced cooling to improve the cooling efficiency and quality. The enhanced cooling component is set on the support roller 6. The enhanced cooling component includes an aeration plate 22. Three sinking installation grooves 21 are opened on the outer peripheral side of the support roller 6. The aeration plate 22 is fixed in the sinking installation groove 21 by bolts. The center of the support roller 6 is connected to the bearing rod 7. A central air groove 19 is opened. The central air groove 19 is connected The sinking installation groove 21 is provided with a plurality of third connecting air grooves 23, the central air groove 19 is located in the annular diverter groove 11 and is provided with a plurality of strip air grooves 20 on one side of the bearing rod 7, and the supporting crossbeam of the lifting roller frame 3 is provided with an air supply distribution groove 24 horizontally. The upper end of the air supply distribution groove 24 is connected to the annular diverter groove 11 and is provided with a connecting groove. The connecting groove is provided with a first one-way valve 25. When the high-pressure air flow is introduced into the air supply distribution groove 24, the high-pressure air flow enters from the position of the first one-way valve 25. After entering the annular diversion groove 11 and being filled with high-pressure airflow, the airflow is divided into two paths for operation. One of the airflows enters the transfer annular groove 16 from the first connecting air groove 14, the first annular matching groove 12, the second annular matching groove 13 and the second connecting air groove 15, and then is ejected from the drainage chute 18 position, further enhancing the sealing of the transfer annular groove 16, and preventing the cooling water outside the bearing box 5 from entering the bearing groove of the bearing box 5. At the same time, the high-pressure airflow disturbs the cooling water on the side of the bearing box 5 and carries the bubbles upward. Another airflow enters the central air groove 19 from the strip air groove 20, and then enters the sinking installation groove 21 from the third connecting air groove 23. Since the aeration plate 22 includes a hard plate frame and a multi-porous elastic diaphragm, the airflow entering the sinking installation groove 21 is finally ejected from the aeration plate 22, so that the cooling water above is filled with bubbles generated by aeration, and then cooperates with the dense bubbles blown out of the bearing box 5 to perform more efficient heat exchange and cleaning of the aluminum alloy workpiece.

[0042] A circulation processing component is set to actively circulate the cooling water in the area where the aluminum alloy workpiece is located above. The circulation processing component includes a number of circulation water pipes 26, and the number of circulation water pipes 26 are respectively fixed at the lower end of the lifting roller frame 3. The number of circulation water pipes 26 are corresponding to the number of support rollers 6. The circulation water pipes 26 are provided with mounting flange pipes near the upper end of the supporting beam. The mounting flange pipes are fixedly connected to the supporting beam. The air supply distribution groove 24 is located below one side of the connecting groove and penetrates the supporting beam. A transfer groove 28 is provided, and a second one-way valve 29 is inserted in the transfer groove 28. An L-shaped butt joint pipe 27 is provided in the center of the mounting flange pipe through the first bracket. The upper end of the vertical section of the L-shaped butt joint pipe 27 is inserted into the lower end of the transfer groove 28, and the horizontal section of the L-shaped butt joint pipe 27 is horizontally inserted into the central axis of the circulation water pipe 26, and the two L-shaped butt joint pipes 27 are located on one side of the circulation water pipe 26. The openings are arranged opposite to each other. The one-way release pressure of the second one-way valve 29 is greater than the one-way release pressure of the first one-way valve 25 and the aeration pressure of the aeration plate 22. When the pressure in the air supply distribution groove 24 is higher than the release pressure of the second one-way valve 29, in addition to the normal high-pressure airflow passing through the transit annular groove 16 and the aeration plate 22 for efficient cooling of the aluminum alloy workpiece, a part of the high-pressure gas will enter the L-shaped butt joint 27, and then under the guidance of the L-shaped butt joint 27, the high pressure will be blown to the other side. At this time, only one of the two air supply distribution grooves 24 can be used. When one of the air supply distribution grooves 24 is in use, due to the one-way blocking effect of the first one-way valve 25, the high-pressure gas fed into the air supply distribution groove 24 cannot pass through the support roller 6 to enter the other air supply distribution groove 24, that is, it is impossible to feed high-pressure airflow into the two L-shaped butt joints 27 at the same time, and the water in the circulating water pipe 26 can only flow in one direction at a time.

[0043] At this time, the cooling water in the circulating water pipe 26 flows to the other side under the action of the high-pressure gas blown out by the L-shaped butt joint 27, so that the cooling water in the cooling water pool 4 is actively circulated. Moreover, when the high-pressure gas sent into the air distribution groove 24 is the high-pressure airflow after cooling by the refrigerator, the water passing through the circulating water pipe 26 can also be cooled again, thereby improving the heat dissipation quality and efficiency of the aluminum alloy above.

[0044] Example 2: On the basis of Example 1, a filter assembly is provided to filter and treat pollutants in the cooling water passing through the circulating water pipe 26. The filter assembly includes two self-rotating sleeves 35. The two self-rotating sleeves 35 are respectively rotated to sleeve the two ends of the circulating water pipe 26. The centers of both ends of the circulating water pipe 26 are horizontally provided with a central mounting rod 30 through a second bracket. The self-rotating sleeve 35 is rotated to sleeve the central mounting rod 30. The central mounting rod 30 passes through one end of the self-rotating sleeve 35 and is provided with a prismatic mounting block. The outer side of the self-rotating sleeve 35 is sleeved with a guide cover 31. The guide cover 31 is fixed to the prismatic mounting block of the central mounting rod 30 by a nut. One side of the self-rotating sleeve 35 A concave filter plate 36 is provided, and a circulation window 32 and a collection box 33 are respectively provided at the upper and lower ends of the guide cover 31. The size of the concave filter plate 36 is set corresponding to the size of the circulation window 32 and the collection box 33. The lower end of the collection box 33 is horizontally connected and provided with a sewage collection pipe 34. Several sewage collection pipes 34 are assembled and set through pipe joints. When the concave filter plate 36 of the rotating sleeve 35 points to the circulation window 32, one of the L-shaped butt joints 27 controls the cooling water in the circulating water pipe 26 to flow in one direction. At this time, the positions of the two concave filter plates 36 respectively realize the circulation of water in and out. At the same time, the concave filter plate 36 can filter the water entering the circulating water pipe 26.

[0045] The self-rotating sleeve 35 is provided with a toggle gear disc 38 on one side outside the guide cover 31, and a horizontal slide groove is provided at the lower end of the support beam of the lifting roller frame 3. A switching gear plate 37 is provided in the horizontal slide groove for horizontal sliding. The lower end of the switching gear plate 37 is engaged with the teeth on one side of the toggle gear disc 38. A push control groove is provided on both sides of the horizontal slide groove in the support beam of the lifting roller frame 3. A pneumatic reciprocating push rod 39 is provided horizontally in the push control groove, and the two ends of the switching gear plate 37 are respectively connected to two pneumatic reciprocating push rods 39. When it is necessary to control the concave filter plate 36 to correspond to the collection box 33, two pneumatic reciprocating push rods 39 are used to control the filter plate 36 to correspond to the collection box 33. The reciprocating push rod 39 pushes the switching tooth plate 37 horizontally, realizing the rotational toggle of the switching tooth plate 37 to the toggle tooth plate 38. At this time, the circulating water pipe 26 and the guide cover 31 remain stationary, and the toggle tooth plate 38 controls the rotating sleeve 35 to rotate 180°, so that the position of the concave filter plate 36 corresponds to the collecting box 33. At this time, the L-shaped docking pipe 27 on the other side sends high-pressure airflow, which can backwash the position of the concave filter plate 36 with air and water flow. The pollutants under the backwash are collected and discharged from the sewage collection pipe 34. The sewage collection pipe 34 and the air distribution groove 24 are both connected by hoses, which does not affect the normal up and down movement of the lifting roller frame 3.
