First of all, in terms of precision control, drawings are the basis for processing special-shaped household appliances (special-shaped) sheet metal parts processing. Before processing, blanking must be carried out strictly according to the drawing dimensions to ensure that the initial dimensions of each component are accurate. Common blanking methods include laser cutting, CNC punching, etc., which can complete the cutting task with high precision.
Secondly, precision control during processing is also critical. In processes such as bending and riveting, it is necessary to accurately select tools and molds according to the dimensions on the drawings and the material thickness to avoid deformation caused by collision between the product and the tool. At the same time, a reasonable processing sequence should be determined to ensure that each step can meet the expected precision requirements.
In terms of quality inspection, size inspection is the primary task. By using measuring tools such as calipers and micrometers, as well as high-precision equipment such as three-coordinate measuring machines, the length, width, height, thickness and other dimensions of special-shaped sheet metal parts are comprehensively measured to ensure that they meet the design requirements.
Shape inspection is also an indispensable part. This includes checking the flatness, verticality, roundness and other shape parameters of the sheet metal parts to ensure that they meet the functional and aesthetic requirements of the product.
In addition, surface quality inspection is equally important. Check the surface of the sheet metal parts for scratches, depressions, protrusions and other defects by visual observation or using equipment such as microscopes to ensure that the surface quality meets the standards.
Material performance testing is also a key link in quality control. Testing the mechanical properties, chemical composition and other aspects of the materials of sheet metal parts can ensure that they meet the relevant standards and requirements, thereby improving the reliability and durability of the products.
Finally, for welded household appliances (special-shaped) sheet metal parts processing, visual inspection and non-destructive testing of the welds are also required. This can ensure that the quality of the welds meets the requirements and avoid cracking, breaking and other problems during use.
