In order to avoid the deformation of aluminum surface, we can adopt the following methods:
1. Reasonable material selection: choose aluminum plate with high strength and rigidity to reduce the influence of external force on aluminum plate and reduce the possibility of surface deformation.
2. Control the machining process: strictly control the application of external force and the change of temperature during machining. In the process of cutting, forming and welding, it is necessary to use appropriate technology and equipment to avoid excessive stress on aluminum plate and excessive heat generation.
3. Avoid overheating: the aluminum plate is easily deformed due to the influence of temperature, and overheating should be avoided when cutting and welding. Control the heating time and temperature and follow the appropriate heating curve to ensure that the aluminum plate can maintain a stable structure during processing.
4. Use appropriate processing tools: Choose appropriate tools such as cutting tools and welding equipment to avoid exerting excessive pressure or heat on the surface of aluminum plate and reduce the possibility of deformation.
5. Reasonable arrangement of working procedures: In the process of processing, the sequence can be appropriately adjusted and the appropriate sequence and method can be adopted for processing. For example, cold working before heat treatment can effectively reduce the deformation of aluminum plate.
6. Strengthen detection and improvement: find surface deformation problems in time and take corresponding measures to improve them. By means of accurate measurement and nondestructive testing, the quality of aluminum plate can be checked, problems can be found in time and corresponding corrective measures can be taken to avoid similar situations from happening again.
To sum up, to avoid surface deformation of aluminum plate, it is necessary to comprehensively consider factors such as material selection, processing technology, tool selection and quality management, and operate in strict accordance with the specified operating procedures to ensure the quality and stability of aluminum plate.
