Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing processes, and in particular to a residual stress equalization device for an aluminum alloy plate. Background Art

[0002] In recent years, with the rapid development of aerospace and automobile manufacturing technology in my country, the demand for high-performance metal materials has continued to increase. Aluminum alloys have been widely used in aerospace, automobile industry and other fields due to their good thermal conductivity, corrosion resistance, light weight and high strength. Most of the workpieces are large aluminum alloy plates, and the material removal rate is over 85%. However, the inherited residual stress generated by raw materials and processing will cause workpiece deformation, greatly affecting the dimensional accuracy and assembly efficiency of structural parts, and even causing serious structural damage to the workpiece, which has huge quality and safety risks. Therefore, it is urgent to solve the problem of workpiece deformation caused by residual stress of aluminum alloy workpieces.

[0003] At present, the methods to reduce residual stress include natural aging, thermal aging, vibration aging, etc.

[0004] The natural aging method is to place the workpiece to be processed in natural conditions for a long time, so that the residual stress in the workpiece can be slowly eliminated through wind and sun exposure. However, the aging period is long and the residual stress reduction level is not high under natural conditions for several months to several years, so it is gradually eliminated in engineering applications.

[0005] Thermal aging is a method of heating the workpiece to a specific temperature at a certain heating rate, keeping it warm for a period of time, and then cooling it to room temperature at a certain cooling rate. However, the thermal aging treatment equipment has high requirements, has certain restrictions on the size of the workpiece, consumes too much energy, and causes serious pollution.

[0006] Vibration aging is to connect the exciter and the workpiece rigidly together. The exciter makes the workpiece resonate with it. The cyclic load and residual stress applied by the exciter are superimposed on the workpiece to reach the yield strength of the material, thereby yielding and releasing the residual stress. However, the exciter in the vibration aging treatment makes the workpiece resonate. The vibration energy is weakest at the point where the amplitude is the smallest on the workpiece vibration mode, that is, the position of the node line. The value superimposed with the residual stress is less than the yield strength of the material, and the organization cannot yield to equalize the residual stress. If the excitation force of the exciter is increased, the surface quality of the workpiece where the resonance amplitude is large is affected by excessive vibration energy, and there is a quality risk of deformation and cracking. Therefore, the effect of vibration aging in equalizing residual stress is limited. Summary of the invention

[0054] The beneficial effects of adopting the above preferred solution are: the aging workbench is conducive to providing installation space for the mechanism for vibrating, heating and displacing the aluminum alloy plate workpiece, and the support column is conducive to providing support for the entire device.

[0055] The working process of the present invention is described below by an embodiment:

[0056] like Figures 1 to 7 As shown, the aluminum alloy sheet workpiece 5 is first subjected to pre-vibration frequency sweeping to obtain the resonance frequency information of each order of the aluminum alloy sheet workpiece 5. There are three methods for obtaining the resonance waveform information of each order: the first method is the sensor testing method, which can be carried out by arranging multiple acceleration sensors 13 on the aluminum alloy sheet workpiece 5 and collecting the corresponding acceleration amplitude information to determine the vibration mode law of each order of resonance; the second method is the sand method, which can be used to cover the aluminum alloy sheet workpiece 5 with sand. Under the action of each order of resonance frequency, the sand will eventually condense in a certain area, which is the vibration mode node line position under the action of each order of resonance; the third method is the simulation analysis method, which can be used to model through simulation analysis software, and the vibration mode under the action of each order of resonance frequency can be calculated using the modal analysis module of the simulation software;

[0057] After the vibration aging mechanism 1 performs pre-vibration frequency sweep on the aluminum alloy plate workpiece 5 to obtain the various frequencies and vibration mode information of the workpiece, the infrared heating lamp tube 213 will act on the node line position of the vibration mode corresponding to the various resonance frequencies of the aluminum alloy plate workpiece 5. During the vibration aging resonance treatment, the infrared heating lamp tube 213 is started to heat the node line position of the vibration mode corresponding to the various resonance frequencies of the aluminum alloy plate workpiece 5 to a certain temperature, keep it warm for a period of time, and then quickly cool it down, so that the area with weak vibration energy at the node line of the vibration treatment vibration mode will undergo yield changes inside the material organization under the action of infrared high temperature, so as to achieve the residual stress reduction and homogenization effect.

[0058] In the above process, when the vibration aging treatment is met, the position and action area of ​​the infrared heating lamp 213 can be adjusted by the lateral displacement guide 42, the vertical displacement guide 411 and the infrared heating horizontal guide 412 to achieve the effect of precise heating, efficient infrared heating-vibration aging residual stress equalization treatment.

[0059] The present invention adopts a method combining infrared heating and vibration aging, which is not limited to the size of the workpiece, has low energy loss and is environmentally friendly. However, when using the traditional thermal aging process, for workpieces with larger dimensions, a larger thermal aging treatment furnace is required, which has high energy loss, expensive equipment, high overall cost and is not environmentally friendly; compared with the traditional single vibration aging treatment, the vibration energy at the peak and trough of the workpiece resonance vibration mode is stronger, and the vibration energy at the node line of the workpiece resonance vibration mode is weaker. The vibration energy at this location is not enough to cause the workpiece to yield and fail to reduce and equalize the residual stress at this location. The technical solution of the present invention performs local infrared heating on the node line of the resonance vibration mode of the workpiece during vibration aging treatment, so that the material structure at this location undergoes a yield change under the dual effects of high temperature and vibration energy, so as to achieve the reduction and equalization of the residual stress at the node line of the vibration aging vibration mode, so that the workpiece can achieve the overall residual stress reduction and equalization effect under the action of infrared heating-vibration aging.

[0060] Secondly, the aging platform system of the device adopts a modular structured design. The motor on the linear guide rail can flexibly drive the movement and positioning of each component. The infrared heating equipment and the infrared heating guide rail seat are connected with a turntable design, so that the infrared heating lamp can achieve 360° free rotation under the control of the infrared heating control display. According to the different resonance vibration modes of the aluminum alloy plate workpiece, the corresponding infrared heating lamp can be added and the working position can be changed to customize the infrared heating-vibration aging process plan.

[0061] The overall structure of the device is simple, the parts are easy to repair and replace, and the equipment and site requirements are not high. The device can be used to achieve integrated residual stress reduction and homogenization processing, without the need for repeated transportation between processes, effectively reducing transportation costs and greatly improving production efficiency. The device has the characteristics of high efficiency, environmental protection, flexibility, etc. The invention can be used to achieve the reduction and homogenization of residual stress in large aluminum alloy plates, reduce the risk of workpiece size deformation and scrapping due to the influence of residual stress, and effectively improve the product qualification rate and shape accuracy of the workpiece.
