Description

Technical Field

[0001] The invention relates to the field of quenching devices, and in particular to an aluminum alloy profile quenching device. Background Art

[0002] Aluminum alloys are widely used in aerospace, construction, automobiles, machinery manufacturing, ships and many other fields due to their excellent properties. However, the hardness of newly made aluminum alloy products is relatively low and it is difficult to meet the actual use requirements. In order to improve the hardness, quenching treatment is required. The key equipment for quenching treatment is the quenching furnace and the quenching tank. The specific process is: first place the aluminum profile in the quenching furnace for heating, and after reaching a specific temperature, put it into the quenching tank for cooling, and finally achieve forming.

[0003] When the traditional quenching tank adopts the batch immersion process, the dense stacking of aluminum profiles leads to the temperature imbalance of the quenching medium, forming a significant temperature gradient in the vertical / horizontal direction, resulting in differences in cooling rates in different areas, triggering the coupling of phase change stress and thermal stress, and in severe cases leading to residual stress in the profile, ultimately causing serious consequences of immediate deformation.

[0004] In order to solve the above problems, the present application proposes an aluminum alloy profile quenching device. Summary of the invention

[0005] (I) Purpose of the invention

[0006] In order to solve the technical problems existing in the background technology, the present invention proposes an aluminum alloy profile quenching device, which has the advantages of increasing the uniformity of cooling, reducing the generation of thermal stress, and improving the forming quality of the profile.

[0007] (II) Technical solution

[0008] In order to solve the above problems, the present invention provides an aluminum alloy profile quenching device, comprising a quenching tank with an upward opening, wherein a placement shell is provided inside the quenching tank and is penetrated vertically and frontally;

[0009] The bottom of the placement shell is connected to a jet knocking mechanism through a rolling support mechanism, and the inner bottom wall of the quenching tank is provided with a wave area adapted to the jet knocking mechanism;

[0010] Both sides of the placement shell are rotatably provided with placement mechanisms for placing profiles, and a rotation mechanism that cooperates with the placement mechanism in transmission is provided inside the placement shell;

[0011] A driving member is assembled on the quenching tank and is used to drive the rolling support mechanism to move. When the driving member operates, the placement shell moves accordingly, enabling the jet knocking mechanism to automatically adapt to the wave area, and then carrying out the actions of liquid suction and liquid jetting onto the profile. During this process, the jet knocking mechanism acts on the placement shell to vibrate. At the same time, the placement mechanism and the rotation mechanism drive each other, causing the profile to rotate.

[0012] Preferably, the rolling support mechanism includes a support frame and rollers. The support frame is located at the bottom of the placement shell and is connected to the rollers. The driving end of the driving member is connected to the support frame.

[0013] Preferably, the placement mechanism includes a turntable and a square rod. The turntable is rotatably arranged on the side of the placement shell, and a hole for placing the profile is provided on the turntable. The square rod is fixedly sleeved in the middle of the turntable.

[0014] Preferably, the rotation mechanism includes a transmission disk, a notch frame, and a right-angle plate. The right-angle plate is installed in the quenching tank and is in transmission cooperation with the transmission disk. The notch frame forms an opening for the square rod to be inserted upwards.

[0015] Preferably, a rack is installed inside the right-angle plate, and the transmission disk is a gear disk meshing with the rack.

[0016] Preferably, the jet knocking mechanism includes a sleeve shell, a moving plate, a rotating roller, an elastic member, a knocking rod, and a mounting block. The sleeve shell is installed at the bottom of the support frame. An inclined upward spray hole is provided on one side of the sleeve shell. The moving plate slides into the sleeve shell and is connected to the inner top wall of the sleeve shell through an elastic member. One end of the knocking rod is fixedly connected to the moving plate, and the other end slides out of the sleeve shell. The mounting block is installed at the bottom of the moving plate and is rotatably connected to the rotating roller through a rotating shaft.

[0017] Preferably, a knocking plate that is struck by the knocking rod is installed at the bottom of the placement shell.

[0018] Preferably, positioning rods are installed at the four corners of the top of the support frame, and one end of each positioning rod slides into the interior of the placement shell.

[0019] Preferably, through holes are provided on the turntable.

[0020] Preferably, quenching cooling liquid is contained inside the quenching tank, and a drain valve is provided on one side of the quenching tank.

[0021] The above technical solutions of the present invention have the following beneficial technical effects:

[0022] Improve quenching uniformity: The turntable in the placement mechanism can drive the profile to rotate. This not only gives each surface of the profile the opportunity to contact the cooling liquid at different locations, but also the rotation process can disturb and mix the cooling liquid, effectively avoiding the problems of insufficient local cooling or over-cooling, significantly improving the quenching uniformity. At the same time, the vibration and liquid spraying generated when the spraying and knocking mechanism works help the cooling liquid to better adhere to the surface of the profile, further enhancing the quenching uniformity and reducing the quality problems caused by uneven cooling.

[0023] Enhance automation and production efficiency: The driving part drives the placement shell to move through the driving rolling support mechanism. During this process, the spraying and knocking mechanism can automatically adapt to the wave area, and at the same time, the placement mechanism and the rotation mechanism drive each other to make the profile rotate. The entire quenching process is highly automated, reducing manual intervention, and thus greatly improving the production efficiency.

[0024] Reduce residual stress: The vibration generated when the spraying and knocking mechanism works will be transmitted to the profile, playing a role in stress removal. Moreover, the rotation and uniform cooling of the profile help to reduce the coupling of phase transformation stress and thermal stress, reducing the residual stress of the profile, reducing the immediate deformation of the profile, and ensuring the quality and performance of the profile.

[0025] Optimize the cooling effect: The through holes opened on the turntable increase the contact area between the cooling liquid and the profile. When the turntable rotates, the cooling liquid forms a more complex flow path, further optimizing the cooling process. This not only improves the quenching quality but also reduces the stress concentration inside the profile, making the profile performance more stable. Description of the Drawings

Specific embodiments

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0035] As Figure 1-7 shown, a quenching device for aluminum alloy profiles proposed by the present invention includes a quenching tank 1 with an upward opening. The interior of the quenching tank 1 is filled with quenching cooling liquid, and a drain valve (not shown in the figure) is provided on one side of the quenching tank 1. Under the action of the drain valve, when the cooling liquid needs to be replaced, it is convenient to drain the liquid. An internally placed shell 2 that penetrates up and down and back and forth is provided inside the quenching tank 1;

[0036] The bottom of the placement shell 2 is connected to a spraying and knocking mechanism 8 through a rolling support mechanism 3, and a wave area 101 adapted to the spraying and knocking mechanism 8 is provided on the inner bottom wall of the quenching tank 1;

[0037] Rotating mechanisms 5 for placing profiles 4 are rotatably provided on both sides of the placement shell 2, and a rotation mechanism 6 in transmission cooperation with the placement mechanism 5 is provided inside the placement shell 2;

[0038] A driving member 7 is assembled on the quenching tank 1 for driving the rolling support mechanism 3 to move. The driving member 7 is a cylinder or a hydraulic cylinder. When the driving member 7 operates, the placement shell 2 moves accordingly, so that the spraying and knocking mechanism 8 is automatically adapted to the wave area 101, and then actions of sucking liquid and spraying liquid onto the profile 4 are carried out. During this process, the spraying and knocking mechanism 8 acts on the placement shell 2 to vibrate. At the same time, the placement mechanism 5 and the rotation mechanism 6 are in mutual transmission, causing the profile 4 to rotate.

[0039] In an alternative embodiment, the rolling support mechanism 3 includes a support frame 31 and rollers 32. The support frame 31 is located at the bottom of the placement shell 2 and is connected to the rollers 32. The driving end of the driving member 7 is connected to the support frame 31, and the wave region 101 is not on the path of the movement of the rollers 32 in the quenching tank 1.

[0040] It should be noted that the support frame 31 is located at the bottom of the placement shell 2, and the driving end of the driving member 7 is directly connected to the support frame 31. When the driving member 7 operates, the power output by it pushes the support frame 31 to move in the horizontal direction. Under the action of the driving force, the support frame 31 drives the connected rollers 32 to roll in the quenching tank 1. The rolling of the rollers 32 provides support and a moving basis for the movement of the placement shell 2, enabling the placement shell 2 to move in the quenching tank 1.

[0041] In an alternative embodiment, the placement mechanism 5 includes a turntable 51 and a square rod 52. The turntable 51 is rotatably arranged on the side of the placement shell 2, and holes for placing the profile 4 are provided on the turntable 51. The square rod 52 is fixedly sleeved in the middle of the turntable 51.

[0042] It should be noted that in the placement mechanism 5, the turntable 51 is rotatably arranged on the side of the placement shell 2, the holes provided on it are used to place the profile 4, and the square rod 52 is fixedly sleeved in the middle of the turntable 51. When the driving member 7 drives the placement shell 2 to move, the square rod 52 interacts with the notch frame 62 in the rotating mechanism 6. As the placement shell 2 continues to move, the turntable 51 rotates, so that the profile 4 rotates continuously. The rotation of the profile 4 can stir the cooling medium in the quenching tank 1. During the quenching process, the rotation of the profile 4 enables all surfaces to fully contact the cooling liquid, greatly improving the uniformity and effect of quenching, avoiding quality problems caused by insufficient or excessive local cooling, and ensuring the overall quality of the profile 4.

[0043] In an alternative embodiment, the rotating mechanism 6 includes a transmission disk 61, a notch frame 62 and a right-angle plate 63. The right-angle plate 63 is installed in the quenching tank 1 and is in transmission cooperation with the transmission disk 61. The notch frame 62 forms an opening upwards for the square rod 52 to be inserted.

[0044] It should be noted that the right-angle plate 63 is fixedly installed in the quenching tank 1, the transmission disk 61 is in transmission cooperation with the right-angle plate 63, and the notch frame 62 forms an opening upwards for placing the square rod 52. When the driving member 7 drives the placement shell 2 to move, the square rod 52 and the notch frame 62 rotate synchronously, which not only improves the uniformity of quenching, reduces manual intervention, but also improves production efficiency and ensures the quenching quality of the profile 4.

[0045] To increase the stability of transmission, a rack 64 is installed inside the right-angle plate 63, and the transmission disk 61 is a gear disk meshing with the rack 64.

[0046] In an alternative embodiment, there are two sets of jet knocking mechanisms 8. The jet knocking mechanism 8 includes a housing 81, a moving plate 82, a rotating roller 83, an elastic member 84, a knocking rod 85, and a mounting block 86. The elastic member 84 is a spring or a spring plate. The housing 81 is installed at the bottom of the support frame 31. An inclined upward spray hole 811 is formed on one side of the housing 81. The moving plate 82 slides into the housing 81 and is connected to the inner top wall of the housing 81 through the elastic member 84. One end of the knocking rod 85 is fixedly connected to the moving plate 82, and the other end slides out of the housing 81. The mounting block 86 is installed at the bottom of the moving plate 82 and is rotatably connected to the rotating roller 83 through a rotating shaft.

[0047] The housing 81 is installed at the bottom of the support frame 31. The moving plate 82 slidably extends into the housing 81 and is connected to the inner top wall of the housing 81 through the elastic member 84. When the jet knocking mechanism 8 moves above the wave area 101 along with the placement housing 2, the undulation of the wave area 101 will cause the rotating roller 83 to move up and down. The rotating roller 83 drives the moving plate 82 to slide up and down in the housing 81 through the mounting block 86. When the moving plate 82 slides upward, the elastic member 84 is compressed. When the moving plate 82 slides downward, the elastic member 84 rebounds. Under the action of the elastic member 84, the moving plate 82 makes a reciprocating motion. On the one hand, the reciprocating motion of the moving plate 82 enables the spray hole 811 on the housing 81 to achieve the suction and spraying of liquid, cooling and mixing the profile 4. On the other hand, the moving plate 82 drives the knocking rod 85 to reciprocate. One end of the knocking rod 85 is fixed on the moving plate 82, and the other end extends out of the housing 81 to knock the knocking plate 87 at the bottom of the placement housing 2, causing the placement housing 2 to vibrate, and then the vibration is transmitted to the profile 4 to relieve stress.

[0048] Through the cooperation with the wave area 101, the jet knocking mechanism 8 utilizes the elastic member 84 to achieve the functions of automatic liquid spraying and vibration, improving the cooling effect and uniformity of quenching, helping to eliminate the stress inside the profile 4, and improving the quality of the profile 4.

[0049] In an alternative embodiment, a knocking plate 87 knocked by the knocking rod 85 is installed at the bottom of the placement housing 2.

[0050] It should be noted that the knocking rod 85 reciprocates under the drive of the moving plate 82. When the knocking rod 85 extends out of the housing 81, it will knock the knocking plate 87 at the bottom of the placement housing 2. After being knocked, the knocking plate 87 transmits the vibration to the placement housing 2, causing the placement housing 2 to vibrate. This vibration will be transmitted to the profile 4 placed in the placement housing 2, causing the profile 4 to vibrate continuously during the cooling process, which helps the cooling liquid to better contact the surface of the profile 4 and improves the cooling efficiency and uniformity.

[0051] The setting of the percussion plate 87 enhances the vibration effect of the jet percussion mechanism 8 on the placement shell 2, further improves the quality of quenching, and reduces the residual stress and deformation problems of the profile 4 caused by uneven cooling.

[0052] In an alternative embodiment, positioning rods 33 are installed at the four corners of the top of the support frame 31, and one end of each positioning rod 33 slides into the interior of the placement shell 2.

[0053] It should be noted that for the positioning rods 33 installed at the four corners of the top of the support frame 31, with one end sliding into the interior of the placement shell 2, during the movement of the placement shell 2, the positioning rods 33 play a guiding and positioning role, ensuring the relative position stability between the support frame 31 and the placement shell 2, preventing the placement shell 2 from shifting or shaking during movement. This can ensure that the jet percussion mechanism 8 can always accurately adapt to the wave area 101 and ensure the stable transmission between the placement mechanism 5 and the rotating mechanism 6.

[0054] The setting of the positioning rods 33 improves the stability and accuracy of the operation of the entire quenching device, ensures the coordinated work of each component, and helps to improve the quenching quality and production efficiency.

[0055] In an alternative embodiment, through holes (not shown in the figure) are provided on the turntable 51, and the number of through holes is multiple and they are evenly distributed.

[0056] For the through holes provided on the turntable 51, during the quenching process of the profile 4, the cooling liquid can flow through the through holes, increasing the contact area between the cooling liquid and the profile 4. When the turntable 51 rotates, the presence of the through holes enables the cooling liquid to form a more complex flow path around the profile 4, further improving the cooling effect and uniformity.

[0057] The setting of the through holes optimizes the cooling process of the profile 4, improves the quenching quality, helps to reduce the stress concentration inside the profile 4, and makes the performance of the profile 4 more stable.

[0058] Working principle:

[0059] Align the square rod 52 with the notch frame 62 and place it into the notch frame 62. Start the driving member 7, and the driving end of the driving member 7 pushes the support frame 31 in the rolling support mechanism 3.

[0060] Movement of the placement shell 2: The support frame 31 drives the rollers 32 to roll in the quenching tank 1, thereby causing the placement shell 2 to move in the quenching tank 1. For the positioning rods 33 at the four corners of the top of the support frame 31, one end slides into the interior of the placement shell 2, playing a guiding and positioning role, ensuring the stable movement of the placement shell 2, preventing deviation or shaking, ensuring the adaptation of the jet percussion mechanism 8 to the wave area 101, and ensuring the stable transmission between the placement mechanism 5 and the rotating mechanism 6.

[0061] Jet knocking mechanism 8: As the placement shell 2 moves, the jet knocking mechanism 8 installed at the bottom of the support frame 31 also moves synchronously. When it reaches above the wave area 101, the undulation of the wave area 101 causes the roller 83 to move up and down. The roller 83 drives the moving plate 82 to slide up and down in the sleeve 81 through the mounting block 86. The moving plate 82 makes a reciprocating motion under the action of the elastic member 84. The reciprocating motion of the moving plate 82 enables the spray holes 811 on the sleeve 81 to suck and spray liquid, cooling the profile 4. At the same time, the moving plate 82 drives the knocking rod 85 to make a reciprocating motion. The knocking rod 85 knocks the knocking plate 87 at the bottom of the placement shell 2, causing the placement shell 2 to vibrate. The vibration is transmitted to the profile 4, which helps to eliminate the internal stress of the profile 4 and improve the quenching uniformity.

[0062] Rotation of profile 4: When the placement shell 2 moves, the turntable 51 and the square rod 52 in the placement mechanism 5 move accordingly. The rotation of the turntable 51 drives the profile 4 to rotate through the square rod 52. In the rotation mechanism 6, the right-angle plate 63 is fixed in the quenching tank 1. The driving disk 61 is in driving cooperation with the right-angle plate 63. The rack 64 inside the right-angle plate 63 meshes with the driving disk 61, ensuring the stability of the transmission and further ensuring the stable rotation of the profile 4.

[0063] Optimizing the cooling effect: The through holes opened on the turntable 51 enable the cooling liquid to flow through the through holes during the quenching process of the profile 4, increasing the contact area between the cooling liquid and the profile 4. When the turntable 51 rotates, the cooling liquid forms a more complex flow path around the profile 4, further optimizing the cooling process, improving the quenching quality, reducing the internal stress concentration of the profile 4, and making the performance of the profile 4 more stable.

Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
