Description

TECHNICAL FIELD

[0001] The present application relates to quenching equipment field, especially to an aluminum alloy online quenching equipment. BACKGROUND

[0002] Quenching is a heat treatment process method of heating metal to above the critical temperature, keeping warm for a certain time, and then cooling at a speed greater than the critical cooling speed. Quenching is the most widely used process method in steel heat treatment process. Usually, the solid solution treatment or heat treatment process with rapid cooling process of aluminum alloy, copper alloy, titanium alloy, tempered glass and other materials is also called quenching. After solid solution treatment and aging, the strength of aluminum alloy can be improved, and useful organization and performance can be obtained.

[0003] During quenching, the shape of aluminum alloy is different, and the local heat dissipation is uneven. The shrinkage force of the side with faster heat dissipation is large, and the shrinkage force of the side with slower heat dissipation is small, which will cause the aluminum alloy to protrude to the side with slower heat dissipation, resulting in bending of the aluminum alloy. When cooling, the heated aluminum alloy is usually directly placed into cooling water or cooling oil, and the cooling speed of the cooling water is faster, which is more likely to cause the aluminum alloy to bend. The cooling oil is relatively moderate, and the cooling speed is relatively slow. When using cooling water or cooling oil alone in ordinary equipment, it is difficult to adjust the cooling speed of the aluminum alloy online, and the aluminum alloy is easy to be heated unevenly during adjustment.

[0033] As a technical optimization scheme of the utility model, four sliding grooves 23 are provided on the mounting plates 17, the four sliding grooves 23 are located around the through material grooves 18 and are spaced 90 degrees along the circumference of the through material grooves 18, electric sliding blocks 22 are slidably installed in the sliding grooves 23, and the both ends of the four copper pipes 19 are detachably connected with the corresponding electric sliding blocks 22. The electric sliding blocks 22 drive the copper pipes 19 to move, so that the efficiency of the copper pipes 19 absorbing heat around the aluminium alloy pieces 6 can be adjusted.

[0034] As a technical optimization scheme of the present application, the electric sliding block 22 is fixedly connected with an L-shaped plate 24 near one side of the center of the oil storage tank 12, the vertical end of the L-shaped plate 24 is connected with the electric sliding block 22, a vertical insertion hole is arranged on the horizontal end of the L-shaped plate 24, an insertion rod 25 is arranged in the insertion hole, one end of the insertion rod 25 away from the material feeding groove 18 is fixedly connected with the copper pipe 19, a magnetic block 26 is fixedly installed on the horizontal end of the L-shaped plate 24, and a magnetic block 26 is also correspondingly installed on the copper pipe 19.

[0035] As a technical optimization scheme of the present application, the four copper pipes 19 are respectively adapted to the shapes of the four sides of the aluminum alloy piece 6, a water guide strip 28 is arranged in the copper pipe 19, and the water guide strip 28 is located on the side away from the first water pipe joint 20 and the second water pipe joint 21. The water guide strip 28 can increase the contact area of the cooling water with the copper pipe 19, increase the heat exchange efficiency, and guide the cooling water entering the copper pipe 19, thereby increasing the flow efficiency of the cooling water in the copper pipe 19.

[0036] As a technical optimization scheme of the present application, the first detection mechanism 7 has two groups, which are respectively installed on the top and one side of the aluminum alloy piece 6. The first detection mechanism 7 comprises a detection plate 30, an installation groove 33 is arranged in the middle of the detection plate 30, a sliding rod 29 is slidingly installed at the bottom of the installation groove 33, a connecting plate 31 is fixedly installed at the top of the sliding rod 29, the connecting plate 31 is located in the installation groove 33, a displacement sensor 39 is arranged at the top of the connecting plate 31, the shell of the displacement sensor 39 is connected with the detection plate 30, and the detection head 34 of the displacement sensor 39 is connected with the connecting plate 31. When the aluminum alloy piece 6 passes through the first detection mechanism 7, the sliding rod 29 is attached to the surface of the aluminum alloy piece 6, when the aluminum alloy piece 6 is deformed, the protrusion or the depression will cause the sliding rod 29 to slide, thereby driving the connecting plate 31 and the detection head 34 to move, so that the worker can timely find that the surface of the aluminum alloy piece 6 is deformed, and the position of the copper pipe 19 can be adjusted to straighten the aluminum alloy piece 6.

[0037] As a technical optimization scheme of the present application, one end of the sliding rod 29 close to the aluminum alloy piece 6 is provided with an inclined surface, a spring 32 is arranged outside the other end of the sliding rod 29 away from the aluminum alloy piece 6, one end of the spring 32 is fixedly connected with the bottom of the connecting plate 31, and the other end is fixedly connected with the inner wall at the bottom of the installation groove 33. The spring 32 allows the sliding rod 29 to be tightly attached to the surface of the aluminum alloy piece 6, and the inclined surface at the bottom of the sliding rod 29 avoids being stuck when the end of the aluminum alloy piece 6 contacts with the sliding rod 29.

[0038] As a technical optimization scheme of the present application, two groups of second detection mechanisms 8 are installed on the side of the secondary cooling box 3 away from the primary cooling box 2, and the structure and installation mode of the second detection mechanism 8 are completely same as the first detection mechanism 7. The second detection mechanism 8 detects the modified aluminum alloy part 6, when there is an error in the straightening of the copper pipe 19 to the aluminum alloy part 6, the second detection mechanism 8 can timely find out, and the position of the copper pipe 19 can be adjusted, so that the straightening effect of the copper pipe 19 to the aluminum alloy part 6 is better, and when the second detection mechanism 8 detects the aluminum alloy part 6 with unqualified bending degree, the staff can timely find out and process the aluminum alloy part 6.

[0039] As a technical optimization scheme of the present application, the two sides of the top of the support plate 5 are provided with limiting grooves 10, the limiting grooves 10 are slidably installed with limiting blocks 37, the bottom of the limiting block 37 is connected with the support plate 5 through the bolt 38, the top of the limiting block 37 is fixedly connected with the limiting plate 9, the top and the bottom of the side of the limiting plate 9 close to the aluminum alloy part 6 are both installed with fixed plates 35, a plurality of rotating shafts 36 are arranged between the two fixed plates 35, and the two ends of the rotating shaft 36 are rotatably connected with the two fixed plates 35. The limiting plate 9 and the rotating shaft 36 limit the aluminum alloy part 6, so that the aluminum alloy part 6 remains stable when moving, avoiding shaking and affecting the detection precision; the limiting block 37 slides in the limiting groove 10 and is fixed through the bolt 38, so that the limiting plate 9 can adapt to more sizes of the aluminum alloy part 6.

[0040] As a technical optimization scheme of the present application, the oil pump 15 is arranged in the primary cooling box 2, the water outlet end of the oil pump 15 is connected with the oil pipe 16, and the end of the oil pipe 16 away from the oil pump 15 is located in the oil storage tank 12. The oil pump 15 and the oil pipe 16 can pump the cooling oil in the secondary cooling box 3 into the oil storage tank 12, circulate with the cooling oil in the oil storage tank 12, and increase the cooling effect of the oil storage tank 12.

[0041] The support plate 5 is installed with a feeding roller connected for conveying the aluminum alloy part 6. In use, the aluminum alloy part 6 heated in the heating box 1 moves towards the primary cooling box 2, sequentially passes through the primary cooling box 2 and the secondary cooling box 3, the primary cooling box 2 sprays the oil to the aluminum alloy part 6, the atomized cooling oil preliminarily cools the aluminum alloy part 6, and then the aluminum alloy part 6 is secondarily cooled by the cooling oil in the secondary cooling box 3. The two-time cooling can make the cooling process relatively gentle and reduce the possibility of deformation and bending of the aluminum alloy.

[0042] When the aluminum alloy piece 6 passes through the first detection mechanism 7, the slide bar 29 is attached to the surface of the aluminum alloy piece 6. When the aluminum alloy piece 6 is deformed, the protrusion or the depression will cause the slide bar 29 to slide, thereby driving the connecting plate 31 and the detection head 34 to move. At this time, the displacement sensor 39 will transmit information to the external processor, and the staff can timely find that the surface of the aluminum alloy piece 6 is deformed. The staff does not need to detect the aluminum alloy piece 6 after it is completely cooled, and the online detection efficiency is higher.

[0043] The spring 32 allows the slide bar 29 to be tightly attached to the surface of the aluminum alloy piece 6. The slope at the bottom of the slide bar 29 avoids being stuck when the end of the aluminum alloy piece 6 contacts the slide bar 29.

[0044] When the aluminum alloy piece 6 moves, the limiting plate 9 and the rotating shaft 36 limit the aluminum alloy piece 6, so that the aluminum alloy piece 6 remains stable during movement and avoids shaking, which affects the detection accuracy. The limiting block 37 slides in the limiting groove 10 and is fixed by the bolt 38, so that the limiting plate 9 can adapt to more sizes of the aluminum alloy piece 6.

[0045] When the aluminum alloy piece 6 passes through the secondary cooling box 3, the cooling oil in the secondary cooling box 3 cools the aluminum alloy piece 6. At this time, the heat of the aluminum alloy piece 6 is absorbed by the cooling oil. Since the cooling oil has good thermal conductivity but low specific heat capacity, when the aluminum alloy piece 6 continuously passes through the oil storage tank 12, the water pump 14 is started. The water pump 14 pumps the cooling water in the water tank 11 into each copper pipe 19 through the first water pipe joint 20, and then flows back into the corresponding water tank 11 through the second water pipe joint 21, forming a circulation. At this time, the heat of the cooling oil is transferred to the cooling water in the copper pipe 19 through the outer wall of the copper pipe 19, reducing the temperature of the cooling oil. Avoiding the need to stir the cooling oil in the oil storage tank 12 due to the gradual deterioration of the cooling effect of the cooling oil on the aluminum alloy piece 6, the temperature around the aluminum alloy piece 6 is not uniform, thereby causing a temperature difference between the two sides of the aluminum alloy piece 6, resulting in bending of the aluminum alloy piece 6;

[0046] According to the thickness and shape of the aluminum alloy piece 6, the cooling speed of the aluminum alloy piece 6 may need to be adjusted. When the cooling speed of the aluminum alloy piece 6 needs to be reduced, the electric sliding block 22 drives the copper pipe 19 to slide away from the aluminum alloy piece 6, reducing the heat absorption speed of the copper pipe 19 around the aluminum alloy piece 6, thereby reducing the cooling speed of the aluminum alloy piece 6. When the temperature of the aluminum alloy piece 6 needs to be reduced faster, the electric sliding block 22 drives the copper pipe 19 to approach the aluminum alloy piece 6. Since the temperature of the cooling water can only reach 100 degrees Celsius, the heat around the aluminum alloy piece 6 can be controlled, and the cooling effect is more obvious. The pump speed of the water pump 14 can also be controlled to adjust the temperature around the aluminum alloy piece 6, which cooperates with the adjustment of the position of the copper pipe 19. The adjustment method can be flexibly selected.

[0047] If the first detection mechanism 7 detects that the aluminum alloy piece 6 is bent upward, the positions of the copper pipes 19 above and below the corresponding aluminum alloy piece 6 can be adjusted to increase the heat dissipation speed above the aluminum alloy piece 6 and reduce the heat dissipation speed below the aluminum alloy piece 6, so that the aluminum alloy piece 6 above is quickly tightened, the shape of the aluminum alloy piece 6 is corrected, the deformation of the aluminum alloy piece 6 is avoided, and the situation that the aluminum alloy piece 6 needs to be straightened after cooling is completed is reduced. When the first detection mechanism 7 detects that the aluminum alloy piece 6 is bent in other directions, the position of the copper pipe 19 can be adjusted correspondingly, the position of the copper pipe 19 is adjusted in time, and the bending degree of the aluminum alloy piece 6 is corrected; compared with straightening the aluminum alloy piece 6 after cooling is completed, the cost of straightening the aluminum alloy piece 6 online is lower, and the straightening is simpler when the aluminum alloy piece 6 is not completely cooled.

[0048] The second detection mechanism 8 detects the corrected aluminum alloy piece 6, the positions of the copper pipes 19 need to be adjusted for aluminum alloy pieces 6 of different shapes and thicknesses, when the straightening of the aluminum alloy piece 6 by the copper pipe 19 has an error, the second detection mechanism 8 can timely find out and adjust the position of the copper pipe 19, so that the straightening effect of the aluminum alloy piece 6 by the copper pipe 19 is better, and when the second detection mechanism 8 detects the aluminum alloy piece 6 with unqualified bending degree, the staff can timely find out and process the aluminum alloy piece 6.

[0049] The specific heat capacity of the cooling water is large, which can absorb more heat. Compared with using only cooling oil for cooling, the size of the oil tank 12 and the secondary cooling tank 3 can be reduced when cooling the same number of aluminum alloy pieces 6, the amount of cooling oil used is reduced, and the equipment cost and floor area are also reduced.

[0050] The mounting plate 17 is detachably connected with the oil tank 12, when quenching aluminum alloy pieces 6 of different shapes, the corresponding mounting plate 17 can be replaced to make the material slot 18 adapt to the aluminum alloy piece 6; the copper pipe 19 is connected with the L-shaped plate 24 on the electric sliding block 22 through the plug rod 25 and the magnetic block 26, which is very convenient to install and disassemble, the copper pipe 19 adapts to the shape of the aluminum alloy piece 6, which can make the cooling effect of the copper pipe 19 on the aluminum alloy piece 6 better, and when the shape of the aluminum alloy piece 6 changes greatly, the corresponding copper pipe 19 can be replaced; the water guide strip 28 on the copper pipe 19 can increase the contact area between the cooling water and the copper pipe 19, increase the heat exchange efficiency, and guide the cooling water entering the copper pipe 19, increase the flow efficiency of the cooling water in the copper pipe 19.

[0051] The oil pump 15 and the oil pipe 16 can pump the cooling oil in the secondary cooling tank 3 into the oil tank 12 to circulate with the cooling oil in the oil tank 12, and increase the cooling effect of the oil tank 12. The displacement sensor 39 used in the embodiment is a square LSM micro displacement sensor.

[0052] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
