Description

Technical Field

[0001] The present invention belongs to the technical field of workpiece stress removal, and particularly relates to a stress removal device and method for aluminum alloy plates. Background Art

[0002] When a metal workpiece is deformed due to external factors (such as force, humidity, temperature field change, etc.) during processing, internal stresses that interact with each other are generated among various parts of the workpiece. If the stresses are not treated, it will cause problems such as deformation, cracking of the workpiece, and changes in the dimensional accuracy and position accuracy of the workpiece. Currently, the commonly used stress removal methods are mainly divided into three types: natural aging method, thermal aging method, and vibration aging method. Among them, the natural aging method eliminates stress by natural placement. This method takes a long time and is difficult to meet the production needs of modern technology;

[0003] The thermal aging method uses heat treatment by placing the workpiece in a thermal aging furnace to slowly eliminate stress. However, this method requires electricity or fuel to maintain the temperature of the thermal aging furnace, resulting in high costs. Moreover, generally, the thermal aging furnace is built in areas far from the city, and the transportation of workpieces will generate unnecessary costs and time;

[0004] For the vibration aging method, the workpiece is made to generate high-frequency resonance through mechanical means, and the stress is eliminated by homogenizing through resonance. The resonance time of a single workpiece often does not exceed one hour, and the resonance equipment is easy to carry, with low cost, high efficiency, and good stress elimination effect, which is the most commonly used stress elimination method;

[0005] However, when vibration aging is carried out, it will drive the workpiece to resonate. When vibrating a plate workpiece (especially a thin plate), it is very likely to cause deformation of the plate. And because it is directly fixed on the workpiece to drive the workpiece to vibrate, this results in only being able to perform aging treatment on one workpiece at a time, making it difficult to remove internal forces from a large number of small workpieces such as plates in a short time. Moreover, after the resonance aging of the workpiece is completed, it is necessary to manually switch the workpiece, which requires the operator to operate at a specific time, which is rather inconvenient. Summary of the Invention

[0006] The purpose of the present invention is to provide a stress removal device and method for aluminum alloy plates. A plate fixing frame is used to fix a plurality of plates, and by driving the plate fixing frame, resonance of multiple plates is achieved to obtain a higher stress removal effect. And the pre-installed structure is set to be able to automatically switch the resonance installation components after resonance ends, achieving the effect of continuous resonance. The preparation of the pre-installed structure can be carried out during resonance, ensuring that the vibrator can work continuously, with higher efficiency, and the operator does not need to operate at a specific time, which is more convenient.

[0021] The first step: Loading of the aluminum - alloy sheet. Lay the aluminum - alloy sheet flat under each resonance plate, and the aluminum - alloy sheets shall not be overlapped.

[0022] The second step: Fixing of the aluminum - alloy sheet.

The operation has higher coherence, without the need for staff to operate on time, and is more convenient to use. Description of the Drawings

[0042] Furthermore, the present invention will be described in detail in conjunction with the schematic diagrams. When detailing the embodiments of the present invention, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, the three-dimensional spatial dimensions of length, width and depth should be included. Embodiment

[0043] Please refer to the attached Figures 1 to 3 As shown, this is the first embodiment of the present invention. This embodiment provides a stress removal device for aluminum alloy plates, including a vibration platform assembly 1, a pre-installation assembly 2 and a temporary storage platform assembly 3. The vibration platform assembly 1 includes a resonance base 11, an installation base 12 and a shock pad 13. There are two installation bases 12 and two shock pads 13. The two installation bases 12 are fixed to the bottom end of the resonance base 11, and the two shock pads 13 are arranged on the ground. The installation base 12 is installed inside the shock pad 13;

[0044] The material of the shock pad 13 is rubber;

[0045] One end of the resonance base 11 is equipped with an exciter, and the exciter is electrically connected to the main control host;

[0046] A resonance mounting assembly 4 is slidably connected above the resonance base 11. The resonance mounting assembly 4 includes a bottom plate 41, guide slide bars 42, and resonance plates 44. There are two guide slide bars 42. A chute for the guide slide bars 42 to slide is provided on the upper surface of the resonance base 11. There are several resonance plates 44, and several resonance plates 44 are evenly installed above the bottom plate 41. Second support frames 43 are fixed at both ends of the bottom plate 41. The resonance plates 44 are located between the bottom plate 41 and the second support frames 43. Several threaded rods 46 are rotatably connected between the second support frames 43 and the bottom plate 41. Both ends of each resonance plate 44 are threadedly connected to a threaded rod 46, and a top frame 45 is installed between the tops of the two threaded rods 46.

[0047] Before vibration aging, place the aluminum alloy plates that need to remove stress under each resonance plate 44, and avoid stacking the aluminum alloy plates. Then, rotate the threaded rods 46 at both ends of the resonance plate 44 one by one, so that the resonance plates 44 move downward one by one from bottom to top, fix the aluminum alloy plates between the resonance plates 44. Then, install the resonance mounting assembly 4 with the fixed aluminum alloy plates above the vibration platform assembly 1 and the pre-installation assembly 2. Then start the exciter, and the exciter drives the vibration platform assembly 1 to vibrate, and at the same time makes the resonance mounting assembly 4 and the fixed aluminum alloy plates resonate together. Through resonance aging, the stress in the aluminum alloy plates can be removed and evenly distributed;

[0048] By using the resonance mounting assembly 4 to install more aluminum alloy plates at the same time, vibration aging can be carried out on more aluminum alloy plates at the same time, improving the efficiency of stress removal.

[0049] In a preferred embodiment, please refer to Figure 4 , the pre-installation assembly 2 includes a first base 21 and a first sliding table 22. The first sliding table 22 is fixed on the upper surface of the first base 21. Two chutes for the guide slide bars 42 to slide are provided on the upper surface of the first sliding table 22.

[0050] In this embodiment, the resonance mounting assembly 4 can be slidably installed above the pre-installation assembly 2. After the resonance mounting assembly 4 on the vibration platform assembly 1 completes vibration aging, pushing the resonance mounting assembly 4 above the pre-installation assembly 2 can push the resonance mounting assembly 4 on the vibration platform assembly 1 away from the vibration platform assembly 1, and install the resonance mounting assembly 4 on the pre-installation assembly 2 above the vibration platform assembly 1, and vibration aging can continue, which is more convenient to operate and has a better effect.

[0051] Secondly, please refer to Figure 4and Figure 5 On one side of the top of the first base 21, a first support frame 23 is fixed. At the top of the first support frame 23, a first electric push rod 24 is fixed. At the output end of the first electric push rod 24 and below the first support frame 23, a motor mounting case 25 is fixed. Inside the motor mounting case 25, two synchronous motors are installed. At the output end of the synchronous motor, a first transmission gear 26 is fixed;

[0052] At the top of the top frame 45, a transmission gear plate 27 is fixed. The first transmission gear 26 and the transmission gear plate 27 are meshed and connected.

[0053] In the above, when switching the resonance mounting assembly 4, the first electric push rod 24 drives the motor mounting case 25 and the first transmission gear 26 to descend, so that the first transmission gear 26 is meshed and connected with the transmission gear plate 27. Then, the first transmission gear 26 is driven to rotate by the synchronous motor, and the transmission gear plate 27 is meshed and moved, driving the resonance mounting assembly 4 to slide on the vibration platform assembly 1 and the pre-installation assembly 2, completing the switching of the resonance mounting assembly 4.

[0054] Secondly, please refer to Figure 5 and Figure 7 together. The temporary storage platform assembly 3 includes a second base 31 and a second sliding table 32. The second sliding table 32 is fixed on the upper surface of the second base 31. On the upper surface of the second sliding table 32, two sliding grooves for the guide sliding bars 42 to slide are opened.

[0055] In the above, the resonance mounting assembly 4 can be slidably mounted above the temporary storage platform assembly 3. After the resonance mounting assembly 4 located on the vibration platform assembly 1 completes the vibration aging, the removed resonance mounting assembly 4 will slide to the upper part of the temporary storage platform assembly 3, waiting for the operator to remove the aluminum alloy plate.

[0056] Furthermore, please refer to Figure 7 . On one side of both the first base 21 and the second base 31, a resonance fixing assembly 5 is installed. The resonance fixing assembly 5 includes a positioning insertion rod 52. The positioning insertion rod 52 is installed on both sides of the resonance base 11. On one side of the positioning insertion rod 52, a guide groove is provided. The positioning insertion rod 52 is slidably connected with the resonance base 11. Below both sides of the resonance base 11, an internal thread gear ring 51 is rotatably connected. The upper half of the positioning insertion rod 52 is in a frustum shape;

[0057] At both ends of the guide sliding bar 42, anti-detachment holes are opened. The shape of the anti-detachment holes is an inverted funnel shape.

[0058] As described above, to ensure that the resonance mounting component 4 installed above the vibration platform component 1 does not slip during resonance, after the resonance mounting component 4 is installed on the vibration platform component 1, the positioning plug rod 52 moves upward and inserts into the positioning slot 53 to restrict the sliding of the guiding slide bar 42, so that the resonance mounting component 4 will not slip off the vibration platform component 1 during the overall resonance of the resonance mounting component 4.

[0059] In a preferred embodiment, please refer to Figure 7 , the lower half of the positioning plug rod 52 is set to be threaded, the lower half of the positioning plug rod 52 is threadedly connected to the internal thread gear ring 51, two second transmission gears 56 are provided on one side of each of the first base 21 and the second base 31, a drive motor 54 is fixed to the output end of the second transmission gear 56, a second electric push rod 55 is fixed to the output end of the drive motor 54, and the second electric push rod 55 is meshed and connected to the drive motor 54.

[0060] In this embodiment, when controlling the lifting of the positioning plug rod 52, the drive motor 54 is pushed out by the second transmission gear 56, so that the second electric push rod 55 and the internal thread gear ring 51 are engaged together. Then, the drive motor 54 drives the second electric push rod 55 to rotate and engage the internal thread gear ring 51 to rotate. Under the action of the thread and the resonance base 11 restricting the positioning plug rod 52, it can slide up and down. When the positioning plug rod 52 slides into the positioning slot 53, the movement of the resonance mounting component 4 can be restricted. When the top end of the positioning plug rod 52 moves below the guiding slide bar 42, the resonance mounting component 4 can slide normally above the vibration platform component 1.

[0061] Secondly, please refer to Figure 2 and Figure 3 , convex plates are provided at both ends of the resonance plate 44, the threaded rod 46 is threadedly connected to the convex plate, and the vertical positions of the convex plates provided at both ends of each resonance plate 44 are different.

[0062] As described above, each resonance plate 44 controls the lifting through the two threaded rods 46 installed at both ends, so that each resonance plate 44 can freely adjust its height, the distance between each resonance plate 44 can be freely adjusted, and aluminum alloy plates with different wall thicknesses can be installed and fixed.

[0063] In this embodiment, the aluminum alloy plate is fixed by the resonance mounting assembly 4, and the resonance mounting assembly 4 with the aluminum alloy plate fixed thereon is mounted on the vibration platform assembly 1 and the pre-mounting assembly 2. The resonance mounting assembly 4 mounted on the vibration platform assembly 1 is reinforced by the resonance fixing assembly 5 to prevent the resonance mounting assembly 4 from sliding on the vibration platform assembly 1 during vibration. The vibration platform assembly 1 and the resonance mounting assembly 4 are driven by the vibrator to resonate, thereby performing resonance aging. After the resonance aging is completed, by controlling the lowering of the motor mounting housing 25, the first transmission gear 26 is engaged with the transmission toothed plate 27, and the first transmission gear 26 is rotated by the synchronous motor inside the motor mounting housing 25, so as to drive the transmission toothed plate 27 and the resonance mounting assembly 4 below the transmission toothed plate 27 to slide together, so that the resonance mounting assembly 4 located above the vibration platform assembly 1 slides onto the temporary storage platform assembly 3, and the resonance mounting assembly 4 on the pre-mounting assembly 2 slides above the vibration platform assembly 1, and after fixing it with the resonance fixing assembly 5, the vibrator is started to perform vibration aging, which makes the internal force removal operation more coherent.

[0065] First step: Aluminum alloy plate filling. The aluminum alloy plates are laid out and placed under each resonance plate 44, and the aluminum alloy plates shall not be overlapped.

Rotate all the threaded rods 46 installed at both ends of the resonance mounting assembly 4 to control the lowering of several resonance plates 44, and clamp and fix the aluminum alloy plates placed under the resonance plates 44 between the two resonance plates 44.

[0067] Third step: Pre-mounting. Mount the resonance plate 44 with the aluminum alloy plate fixed thereon above the vibration platform assembly 1, and fix the resonance mounting assembly 4 through the resonance fixing assembly 5. In addition, the resonance plate 44 with the aluminum alloy plate installed is also mounted above the pre-mounting assembly 2.

[0069] Step 5: Automatic switching. After the vibration aging is completed, the resonance fixing component 5 releases the fixation on the resonance mounting component 4, and simultaneously drives the two resonance mounting components 4 installed on the vibration platform component 1 and the pre-installation component 2 to translate through the pre-installation component 2. The resonance mounting component 4 that has undergone resonance moves to the temporary storage platform component 3, while the resonance mounting component 4 originally on the pre-installation component 2 moves above the vibration platform component 1 and continues the vibration aging after being fixed by the resonance fixing component 5;

[0070] Step 6: Manual unloading. After the switching of the resonance mounting component 4 is completed, manually remove the resonance mounting component 4 that has undergone vibration aging, and unload the aluminum alloy plate fixed inside the resonance mounting component 4. Then, reload the aluminum alloy plate that has not undergone resonance aging into the resonance mounting component 4 and install it above the pre-installation component 2 waiting for switching.

[0071] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.

The resonance installation component (4) that has undergone resonance moves to the temporary storage platform component (3), while the resonance installation component (4) originally on the pre - installation component (2) moves above the vibration platform component (1), and after being fixed by the resonance fixing component (5), continues to perform vibration aging. Step 6: Manual unloading. After the resonance installation component (4) is switched, manually remove the resonance installation component (4) that has undergone vibration aging, and remove the aluminum alloy plate fixed inside the resonance installation component (4). Then, reload the aluminum alloy plate that has not undergone resonance aging into the resonance installation component (4), and install it above the pre-installation component (2) waiting for switching.
