Description

Technical Field

[0001] The present application relates to the technical field of heat treatment equipment, and in particular to an online water-cooling quenching device and method for automobile aluminum profiles. Background Art

[0002] Automotive aluminum profiles refer to aluminum alloy profiles used in automobile manufacturing, which are widely used in many aspects such as body structure, chassis, interior, engine parts, etc. Aluminum profiles are becoming more and more popular in the automotive industry, mainly due to their advantages such as lightweight, corrosion resistance, high strength, and strong plasticity. Water-cooled quenching is a metal heat treatment process that is mainly used to improve the hardness and strength of metal materials, change the microstructure of the material through rapid cooling, and improve its performance. Water-cooled quenching is widely used in machinery manufacturing, automobile industry, tool manufacturing and other fields.

[0003] According to the quenching method, it can be divided into online quenching and offline quenching. Online quenching means that in the production process, the workpiece is quenched immediately after processing. This method is usually closely integrated with the production line and can improve production efficiency.

[0004] For example, in the existing Chinese patent with publication number CN114438297B, an online water-cooled quenching device for aluminum profiles and an aluminum profile production line are disclosed. Through the above-mentioned prior art, the first electric push rod is operated to push the aluminum rod into the heating furnace intermittently and uniformly for preheating, the driving mechanism controls the cutting machine to move back and forth, and the aluminum rod is cut into several sections of equal length, the transportation mechanism transports the cut aluminum rod to the second frame, and the hydraulic cylinder squeezes it into the mold to generate an aluminum profile, and then the water-cooled quenching mechanism sprays water on the aluminum profile for quenching, and finally enters the third frame to complete the whole process.

[0005] However, the above prior art has the following technical defects: When the above-mentioned prior art performs online cooling and quenching on aluminum profiles, it mainly uses nozzles that are rotatably arranged on multiple water pipes to atomize direct cooling water into a spray, and quenches the aluminum profiles by rotating spraying under the drive of a rotating mechanism to prevent the direct cooling water from causing deformation of the aluminum profile. During the water-cooling quenching process, aluminum profiles are prone to thermal deformation, especially for long strips or thin-walled profiles. The above-mentioned device atomizes direct cooling water into a spray and acts on the aluminum profile in a spraying manner, but when the aluminum profile passes through the water-cooling quenching mechanism and the rotating mechanism components, the entire aluminum profile is in a suspended state, and there are no components to clamp or support the aluminum profile. It is still easy for the aluminum profile to bend and deform, thereby affecting subsequent processing and use.

[0006] Secondly, when the above device is used to cool and quench the aluminum profile, although the rotation mechanism can drive the three nozzles to rotate to expand the spraying area, it is only the rotation of the nozzles themselves that has a certain effect of expanding the spraying area. However, in the actual process of spraying cooling water, due to the distribution limitations of the nozzles, there will still be quenching dead corners, resulting in uneven cooling, which will lead to uneven distribution of the hardness and strength of the aluminum profile, affecting the overall performance.

[0007] Based on this, on the basis of the existing online water-cooling quenching device for aluminum profiles and aluminum profile production lines, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-Figure 18 This application is described in further detail.

[0042] The embodiment of the present application discloses an online water-cooling quenching device and method for automobile aluminum profiles, which can perform online water-cooling quenching on aluminum profiles, and can apply cooling water to the surface of the aluminum profiles in all directions. At the same time, the aluminum profiles are clamped and limited during the quenching process to prevent deformation during the cooling process.

[0043] Embodiment 1: Reference Figure 1 and Figure 2As shown, in the first aspect, the present application provides an online water-cooling quenching device for automobile aluminum profiles, comprising a main workbench 1 and an auxiliary workbench 12 placed symmetrically. In this embodiment, the auxiliary workbench 12 is preferably equipped with nine conveying rollers 13 that are equidistantly rotated toward one side of the main workbench 1. The nine conveying rollers 13 can rotate independently and freely when driven by a driving force; the main workbench 1 and the auxiliary workbench 12 are combined with the production line to receive the long aluminum profiles that have been processed and heated, such as the aluminum profile workpiece shape on the conveying roller 13 in the figure. The main workbench 1 and the auxiliary workbench 12 are provided with a pushing mechanism 2, a cooling unit 3 and a conveying device 4 in sequence; after the workpiece is heated and pushed onto the conveying roller 13, the pushing mechanism 2 can push the workpiece toward the cooling unit 3 when one end of the workpiece moves to the cooling unit 3, and the cooling unit 3 is started to run, and the workpiece can be clamped and limited first, which can play the effect of supporting the workpiece on the one hand, and on the other hand, can prevent the workpiece from thermal deformation when the workpiece is water-cooled and quenched. After the workpiece is clamped and limited, the workpiece is cooled in all directions. Finally, the conveying device 4 can convey the quenched workpiece outward.

[0044] Reference Figure 2 As shown, specifically, the pushing mechanism 2 includes a conveyor belt 21 rotatably arranged on the main workbench 1 toward the side of the auxiliary workbench 12, and a pushing rod 22 is installed on the conveyor belt 21. When the conveyor belt 21 is in operation and rotation, the pushing rod 22 can be driven to rotate elliptically on one side of the main workbench 1, thereby pushing the aluminum profile workpiece located on the conveying roller 13 to move toward the cooling unit 3; a center seat 23 is arranged in the middle of the main workbench 1 and the auxiliary workbench 12, and a middle groove 101 for installing the center seat 23 is opened on the main workbench 1 and the auxiliary workbench 12, and a centering component 8 is provided on the center seat 23 for correcting the position of the workpiece so that the workpiece can be kept in a centered state and pushed toward the cooling unit 3.

[0045] After the heating is completed, one end of the aluminum profile workpiece pushed off the line onto the conveying roller 13 is pushed by the push rod 22, and moves toward the center seat 23. After the workpiece reaches the bottom of the center seat 23, the centering component 8 corrects the position of the workpiece to ensure that the workpiece is in the middle of the main workbench 1 and the auxiliary workbench 12. As the push rod 22 continues to push, one end of the workpiece will enter the cooling unit 3, and the workpiece can be fully water-cooled and quenched with the push of the push rod 22.

[0046] Reference Figure 3 and Figure 4As shown, considering that in the process of pushing the aluminum profile, the position of the aluminum profile needs to be corrected and kept in the center position to enter the cooling unit 3, the centering component 8 includes two rectangular frames 81 symmetrically slidably arranged in the center seat 23, and the center seat 23 is symmetrically provided with a bottom slide 231 for the installation of the rectangular frame 81. In this embodiment, three bottom rollers 82 are preferably equidistantly rotated in the center seat 23, and the three bottom rollers 82 are all in the two rectangular frames 81. It should be noted that the bottom rollers 82 and the conveying rollers 13 are on the same horizontal plane at the same height, so that the workpiece can be pushed by the push rod 22 and can smoothly enter the bottom rollers 82, and the bottom rollers 82 support the workpiece. Three groups of limiting blocks 83 are equidistantly arranged on one side of the rectangular frame 81, and a convex ring 84 is provided between each group of limiting blocks 83 for limited rotation. Three groups of limiting blocks 83 are arranged on one side of the two rectangular frames 81, and each group of two limiting blocks 83 is symmetrically arranged on one side of the rectangular frame 81. The bottom supporting roller 82 is sleeved with a limiting side wheel 85 connected to the convex ring 84. The limiting side wheel 85 is fixedly connected to the convex ring 84. The bottom supporting roller 82 and the limiting side wheel 85 at different positions can rotate independently when driven.

[0047] Reference Figure 5 As shown, in order to facilitate the staff to adjust the spacing of the limiting side wheels 85 on each bottom roller 82 according to the size of the aluminum profile workpiece at the same time to ensure that the aluminum profile is always in the center position, a regulating round rod 86 is rotatably installed on the side wall of the center seat 23, and the center seat 23 has a transfer groove 232 for installing the regulating round rod 86. One end of the regulating round rod 86 is provided with a bidirectional threaded rod 87 that penetrates the two rectangular frames 81, and the two rectangular frames 81 are penetrated with threaded through holes 811 that are compatible with the bidirectional threaded rod 87. Rotating the regulating round rod 86 drives the bidirectional threaded rod 87 to rotate, and it can cooperate with the threaded through holes 811 opened on the rectangular frames 81 to synchronously drive the two rectangular frames 81 to slide symmetrically. That is, when the regulating rod 86 is rotated forward, the two rectangular frames 81 can be driven to slide synchronously toward the middle of the central seat 23, and the distance between the two rectangular frames 81 is reduced; conversely, the two rectangular frames 81 can be driven to slide toward the two inner side walls of the central seat 23 at the same time, and the distance between the two rectangular frames 81 is expanded.

[0048] According to the size of the workpiece, the staff rotates the regulating rod 86 from the outside to adjust and reduce the distance between the two rectangular frames 81. When the rectangular frame 81 moves, it will simultaneously drive the limiting side wheels 85 on the bottom roller 82 to move, that is, the distance between the two limiting side wheels 85 on the bottom roller 82 is reduced until they contact both sides of the workpiece, so that the workpiece can always be kept in the center position and pushed into the cooling unit 3.

[0049] Reference Figure 6 and Figure 7As shown, since the aluminum profile needs to be subjected to all-round water-cooling quenching to avoid the existence of quenching dead corners, which leads to uneven distribution of hardness and strength of the aluminum profile and affects the overall performance, the cooling unit 3 includes an equipment seat 31 clamped on the main workbench 1 and the auxiliary workbench 12, and the equipment seat 31 is symmetrically limited and slidably provided with two side clamping rods 33 through the T-shaped end block 32, and the side clamping rod 33 is fixedly connected to the T-shaped end block 32; the equipment seat 31 is provided with an end slide 311 for sliding installation of the T-shaped end block 32, and a two-way cylinder 34 with telescopic ends respectively connected to the two T-shaped end blocks 32 is installed at the end slide 311; the two-way cylinder 34 can be started to synchronously control the displacement of the two side clamping rods 33 through the two T-shaped end blocks 32.

[0050] The main cooling seat 35 and the auxiliary cooling seat 36 are respectively clamped on one side of the two side clamping rods 33, and the equipment seat 31 is symmetrically provided with side grooves 312 for the installation of the main cooling seat 35 and the auxiliary cooling seat 36; it should be noted that the shapes of the main cooling seat 35 and the auxiliary cooling seat 36 are adapted to the shape of the aluminum profile workpiece, and when the main cooling seat 35 and the auxiliary cooling seat 36 are driven and combined together, they can be clamped on the workpiece. The equipment seat 31 is provided with a water storage mechanism 5 for storing and circulating cooling water. The two-way cylinder 34 starts to shrink and can drive the main cooling seat 35 and the auxiliary cooling seat 36 to clamp on the workpiece by driving the two side clamping rods 33 to move, and then the water storage mechanism 5 cooperates with the main cooling seat 35 and the auxiliary cooling seat 36 to act on the workpiece surface in all directions without dead angles.

[0051] Reference Figures 8 to 10 As shown, in order to allow the cooling water to act on the surface of the aluminum profile quickly and comprehensively, and to allow the cooling water after use to be quickly cooled and recycled, the water storage mechanism 5 includes a receiving box 51 installed in the equipment seat 31 and located below the main cooling seat 35 and the auxiliary cooling seat 36. The receiving box 51 has a water flow port 511. A small air cooler 53 is provided on the lower side of the equipment seat 31 through a hanging rod 52. When the small air cooler 53 is in operation, it can blow cold air in the direction of the water flow port 511. A water storage tank 54 is placed under the equipment seat 31; before use, the water storage tank 54 needs to be filled with cooling water for water-cooled quenching of aluminum profile workpieces.

[0052] Both the main cooling seat 35 and the auxiliary cooling seat 36 have a water groove 351, and a water injection hole 352 and a drainage hole 361 connected to the water groove 351 are respectively provided on the main cooling seat 35 and the auxiliary cooling seat 36. It should be noted that the diameter of the water injection hole 352 is larger than the drainage hole 361. When the main cooling seat 35 and the auxiliary cooling seat 36 are clamped on the workpiece, the water groove 351 on the main cooling seat 35 and the auxiliary cooling seat 36 will form a combined inner cavity for cooling water to flow. A water supply component 6 connected to the main cooling seat 35 is provided on one side of the equipment seat 31, which is used to continuously transport the cooling water from the water tank 54 to the water groove 351 through the water injection hole 352, so that the cooling water acts on the surface of the workpiece in all directions.

[0053] Reference Fig.11 and Fig.12 As shown, considering the need to quickly and continuously transport the cooling water in the water tank 54 to the water injection hole 352 on the main cooling seat 35, the water supply assembly 6 includes a small water pump 61 installed on one side of the equipment seat 31, and the small water pump 61 is respectively installed with an extraction pipe 62 extending down to the bottom of the water tank 54 and a middle pipe 63 extending into the side groove 312. The equipment seat 31 is provided with a configuration hole groove 313 which is connected to the side groove 312 and for the installation of the middle pipe 63. The main cooling seat 35 is provided with a water injection pipe 64 at the water injection hole 352, and the water injection pipe 64 is connected to the middle pipe 63 by a folding hose 65. When the main cooling seat 35 is driven to move out of the side groove 312 and engage with the workpiece, the folding hose 65 will be stretched and lengthened.

[0054] After the workpiece enters the equipment seat 31 and is clamped by the main cooling seat 35 and the auxiliary cooling seat 36, the small water pump 61 is started to transport the cooling water in the water tank 54 to the water injection pipe 64 on the main cooling seat 35 through the extraction pipe 62. The cooling water enters the water groove 351 through the water injection hole 352. The cooling water will fill the closed-loop inner cavity formed by the merging of the water grooves 351 in the main cooling seat 35 and the auxiliary cooling seat 36, and finally be discharged through the drainage hole 361 at the bottom of the auxiliary cooling seat 36, so that the cooling water flows through the workpiece surface in all directions, and the continuous push of the push rod 22 is combined to achieve the purpose of water-cooling quenching of the workpiece. At the same time, under the clamping limit of the main cooling seat 35 and the auxiliary cooling seat 36, it can also prevent the aluminum profile workpiece from thermal deformation and bending without support during the water-cooling quenching process.

[0055] The cooling water discharged through the drain hole 361 will fall into the receiving box 51, and then flow back to the water storage tank 54 through the water outlet 511 on the receiving box 51. The temperature of the cooling water just used for quenching will increase, and when the cooling water falls into the water storage tank 54 through the water outlet 511, the cold air blown by the small air cooler 53 can cool the cooling water to quickly reduce the temperature of the cooling water and avoid excessive temperature in the water storage tank 54. After the cooling water flows back to the water storage tank 54, it can be recycled, thereby improving the water-cooled quenching efficiency of the equipment.

[0056] Reference Fig.13 and Fig.14 As shown, since it is necessary to support the aluminum profile after water-cooling quenching to prevent bending and deformation and to send it out, the conveying device 4 includes a rectangular support plate 41 installed between the main workbench 1 and the auxiliary workbench 12 and located on one side of the equipment seat 31. It should be noted that the upper side of the rectangular support plate 41 is at the same horizontal height as the conveying roller 13 and the bottom roller 82. When the push rod 22 pushes the workpiece, the workpiece can be smoothly moved to the rectangular support plate 41 and supported by the rectangular support plate 41 to prevent the workpiece from being suspended and bent. The rectangular support plate 41 is symmetrically and slidably provided with two side drive rod seats 42, and the rectangular support plate 41 is provided with a limit slide 411 for the side drive rod seats 42 to be slidably installed. A middle L-shaped plate 43 is provided at the bottom of the driving rod seats 42 on both sides. The middle L-shaped plate 43 is fixedly installed at the bottom of the driving rod seats 42 on both sides. When the middle L-shaped plate 43 is subjected to driving force, it can drive the driving rod seats 42 on both sides to slide in the limiting slide 411; two end L-shaped plates 44 are symmetrically arranged on the lower side of the rectangular support plate 41, and the two end L-shaped plates 44 are fixedly connected to the rectangular support plate 41; a clamping unit 7 is provided on the middle L-shaped plate 43 and the end L-shaped plate 44, which is used to control the workpiece after water-cooling quenching and can send it outward to achieve the purpose of discharging.

[0057] Reference Fig.14 and Fig.15 As shown, in order to clamp the end of the quenched aluminum profile and facilitate its clamping and outward transportation, the clamping and conveying unit 7 includes a clamping rod 72 that is rotatably arranged in the side drive rod seat 42 through the inner round rod 71, and the clamping rod 72 and the inner round rod 71 are fixedly connected; the side drive rod seat 42 is provided with an assembly groove 421 for the clamping rod 72 and the inner round rod 71 to be installed. The inner round rods 71 ​​in the drive rod seats 42 on both sides are sleeved with transmission gears 73, the middle L-shaped plate 43 is provided with a driving cylinder 74, and the telescopic end of the driving cylinder 74 is provided with a frame-shaped rack 75 meshing with the two transmission gears 73, and the middle L-shaped plate 43 has a round through hole 431 and a rectangular hole 432 for the driving cylinder 74 and the frame-shaped rack 75 to be installed.

[0058] When the driving cylinder 74 is started, the frame-shaped rack 75 can be driven to slide, thereby simultaneously driving the inner round rod 71 and the clamping rod 72 installed in the driving rod seats 42 on both sides to rotate toward the middle of the rectangular support plate 41 through the two transmission gears 73.

[0059] Reference Fig.15 and Fig.16 As shown, a bidirectional screw 76 with threads penetrating the middle L-shaped plate 43 is rotatably installed between the two end L-shaped plates 44, and an internal threaded hole 433 adapted to the bidirectional screw 76 is penetrated and opened on the middle L-shaped plate 43. A driving motor 77 is provided on the end L-shaped plate 44, and a transmission belt 78 is sleeved between the rotating end of the driving motor 77 and the bidirectional screw 76. When one end of the workpiece moves to the rectangular support plate 41 after water-cooling quenching and is located between the two side drive rod seats 42, the driving cylinder 74 is started to drive the inner round rod 71 and the clamping rod 72 in the two side drive rod seats 42 to rotate through the meshing of the frame-shaped rack 75 and the two transmission gears 73 until the two clamping rods 72 are clamped on both sides of the workpiece.

[0060] Then the driving motor 77 is operated, and the bidirectional screw rod 76 is driven to rotate through the transmission belt 78. The rotating bidirectional screw rod 76 cooperates with the internal threaded hole 433 provided on the middle L-shaped plate 43, and can drive the driving rod seats 42 on both sides to slide in the limit sliding opening 411. That is, the workpiece after water-cooling quenching is clamped and sent out.

[0061] After the workpiece is completely separated from the main cooling seat 35 and the auxiliary cooling seat 36, the two-way cylinder 34 drives the two to separate and reset, and the small water pump 61 stops running. After the two-side drive rod seats 42 reach the other end of the rectangular support plate 41, the drive cylinder 74 contracts to drive the inner round rod 71 and the clamping rod 72 to rotate and reset to release the clamping of the workpiece; the drive motor 77 continues to operate to rotate the two-way screw 76 to drive the middle L-shaped plate 43 and the two-side drive rod seats 42 back to the initial position.

[0062] Embodiment 2: Reference Fig.17As shown, on the basis of the first embodiment, considering that after the water-cooling quenching is completed, the aluminum profile is clamped on the rectangular support plate 41 and transported outward, it can further prevent the aluminum profile from thermal deformation, which affects the subsequent processing and use. During the transportation process, the upper side of the aluminum profile can be restricted, and a top restriction member 9 is further provided on one side of the equipment seat 31 on the auxiliary workbench 12. The top restriction member 9 includes a control panel seat 91 installed on the auxiliary workbench 12 and located above the rectangular support plate 41. One side of the control panel seat 91 is provided with a convex frame rod 92 to limit the upper and lower sliding positions. There is a limiting strip 93, and a vertical sliding groove 911 is provided on one side of the control panel seat 91 for the convex frame rod 92 to slide and install. The control panel seat 91 is located in the vertical sliding groove 911 and is rotatably provided with a driving screw 94 with threads penetrating the convex frame rod 92, and one end of the driving screw 94 penetrates the control panel seat 91 and extends upward. A through threaded hole 921 adapted to the driving screw 94 is penetrated on the convex frame rod 92, and a round rod hole 912 is provided on the control panel seat 91, which is connected with the vertical sliding groove 911 and for the driving screw 94 to penetrate and extend out, and an adjusting round button 95 is provided at the protruding end of the driving screw 94.

[0063] After waiting for the clamping rod 72 to rotate and clamp on both sides of the workpiece, the staff rotates the adjusting knob 95 to drive the driving screw 94 to rotate, and cooperates with the through threaded hole 921 opened on the convex frame rod 92 to drive the limiting strip plate 93 to move down until the lower side of the limiting strip plate 93 contacts the upper side of the workpiece, thereby achieving the purpose of limiting the upper side of the workpiece. Prevent the workpiece from thermal deformation during the process of conveying the material out shortly after the water-cooling quenching is completed.

[0064] Reference Fig.18 As shown, on the other hand, the present application also discloses an online water-cooling quenching method for automobile aluminum profiles, and the quenching method has the following steps: The first step is to push and center: after the aluminum profile workpiece is processed and heated, it is moved from the offline to the main workbench 1 and the auxiliary workbench 12. A plurality of conveyor rollers 13 support the aluminum profile workpiece, and the pushing mechanism 2 operates to adjust the position of the aluminum profile workpiece to the center and then push it to the cooling unit 3; specifically, after the workpiece is offline to the conveyor roller 13, the conveyor belt 21 is started to drive the pushing rod 22 to push the workpiece toward the center seat 23. Then, according to the size of the workpiece, the regulating rod 86 is rotated to adjust and reduce the spacing of the limiting side wheels 85 on the bottom roller 82 until it contacts both sides of the workpiece. Under the continuous push of the pushing rod 22, the workpiece can be kept centered and pushed to the position of the equipment seat 31.

[0065] The second step is to merge restrictions: after the aluminum profile workpiece is pushed to the position of the cooling unit 3, the two-way cylinder 34 is started to drive the main cooling seat 35 and the auxiliary cooling seat 36 to engage on the aluminum profile workpiece to prevent thermal deformation of the workpiece during water-cooling quenching; at the same time, when the main cooling seat 35 and the auxiliary cooling seat 36 are engaged and clamped on the workpiece, the water-passing grooves 351 on the main cooling seat 35 and the auxiliary cooling seat 36 will form a closed inner cavity.

[0066] The third step is water cooling: the water storage mechanism 5 operates and cooperates with the main cooling seat 35 and the auxiliary cooling seat 36 that are combined and clamped on the workpiece to perform all-round water-cooling quenching on the workpiece; the small water pump 61 is started to transport the cooling water in the water storage tank 54 to the water groove 351 through the water injection hole 352, and the cooling water flows through the surface of the workpiece in all directions, and finally discharged through the drainage hole 361 at the bottom of the auxiliary cooling seat 36. In addition, under the clamping limit of the main cooling seat 35 and the auxiliary cooling seat 36, thermal deformation and bending of the workpiece can be prevented during the water-cooling quenching process.

[0067] When the cooling water falls into the water storage tank 54 through the water flow port 511, the small air cooler 53 can cool the cooling water to avoid overheating in the water storage tank 54. After the cooling water flows back into the water storage tank 54, it can be used again.

[0068] Step 4: Clamping and conveying: Finally, the quenched aluminum profile workpiece is conveyed outward under the operation of the conveying device 4. When one end of the workpiece is pushed and moved to the rectangular support plate 41 between the two side drive rod seats 42, the driving cylinder 74 is started to drive the inner round rod 71 and the clamping rod 72 in the two side drive rod seats 42 to rotate to clamp the two sides of the workpiece. The staff turns the adjustment knob 95 to drive the limiting strip 93 to move down to contact the workpiece to limit the upper side of the workpiece.

[0069] Finally, the driving motor 77 is operated to drive the bidirectional screw rod 76 to rotate, and the driving rod seats 42 on both sides are driven to slide in the limit sliding openings 411, so as to clamp the workpiece after water-cooling quenching and send it out.

[0070] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
