precision sheet metal profiling
Product Description
Precision sheet Metal forming refers to the comprehensive use of computer technology, new material technology, precision processing and measurement technology and other modern technology, through shaping deformation, cutting, welding and other forming means of metal sheet processing into the predetermined design of the product, the purpose is to make formed products to reach the shape or size of the reservation design requirements. The appearance of precision sheet metal forming industry as the junction of sheet metal processing industry and machinery industry is the product of the development of science and technology and the further division of labor in manufacturing industry in the last thirty years.
Precision sheet metal forming technology
Precision sheet metal forming technology is the metal sheet material, profile, pipe and other semi-finished products, using the plasticity of the material, in the case of no cutting into a variety of thin-wall parts processing technology. Forming process is closely related to machine tools and process equipment (molds, etc.). The development of this technology not only improves the technological level of sheet metal, but also improves the forming quality of sheet metal parts and the level of sheet metal mechanization automation, reducing manual labor. Its research scope includes: automatic control technology of aircraft sheet metal forming deformation; Research on the process and detection method of superplastic forming/diffusion bonding structure; Study on shot peening technology of integral wainscot; Research on sheet metal flexible manufacturing system. The characteristics of sheet metal parts processing are mainly determined by the structural characteristics and production mode of aircraft. Sheet metal parts constitute the frame and aerodynamic shape of the aircraft body, parts of different sizes, complex shapes, different selection of materials, output, variety. Large aircraft have about 35,000 sheet metal parts, of which there are only one or two in individual items. In addition, the parts have a more complex shape, strict weight control and a certain service life requirements, and after forming parts of the mechanical properties of the material has a certain index, compared with other industries of sheet metal parts, high technical requirements, processing difficulty. Its processing method in addition to the use of traditional methods, and the industry's unique technology. In terms of the level of technology, the difficulty of processing varies greatly from manual operation, semi-mechanization to flexible manufacturing systems.
Application analysis
With the further development of aviation manufacturing technology, precision sheet metal forming technology such as superplastic forming technology, laser impact, diffusion connection, rubber bag hydroforming and laser forming and other precision sheet metal forming in foreign countries is developing very rapidly, but there is still a big gap between China and the international advanced level. Therefore, we should start from the overall survival and development of the aviation industry, consider the comprehensive benefits of technology and economy, and constantly improve the work efficiency of sheet metal forming, improve the quality of sheet metal forming.
(1) The application of precision sheet metal forming technology saves materials and workload, thus greatly saving military expenditure, so that effective funds play a greater role;
② As the strength, stiffness and corrosion resistance of precision sheet metal parts are improved, the production quality is improved, so that the combat performance of weapons is improved;
(3) Due to the emergence of flexible manufacturing system to solve the small batch, multiple varieties of sheet metal parts production, reduce the production cost, greatly improve the market response speed, new product development, conversion fitness, so as to shorten the development and production cycle.
Sheet metal technology is widely used in aviation manufacturing, the improvement of its processing technology level can greatly improve the performance of aircraft, and the change of aircraft structure and promote the sheet metal technology forward, the two complement each other. Precision sheet metal technology as an advanced processing method of aircraft sheet metal parts, its continuous application in the field of aviation manufacturing will greatly promote the development of aviation manufacturing technology.
