How to avoid waste in the sheet metal processing process?

In all kinds of sheet metal processing, materials are the basis and one of the costs, so we must pay attention to avoid waste when calculating.


In the process of sheet metal processing, according to the basic processing methods of sheet metal parts, such as material, bending, stretching, forming, and welding. According to the different processing methods, the blanking can be divided into general punching, number punching, shear cutting, laser cutting, and wind cutting. Due to the different processing methods, the processing technology of the blanking is also different. Sheet metal blanking methods are mainly digital punching and laser cutting. The advantage of laser cutting is that the thickness of the processed plate is large, the shape of the cut workpiece is fast, and the processing is flexible. The disadvantage is that it cannot be processed into shape. Mesh parts are not suitable for processing in this way, and the processing cost is high. Welding methods mainly include arc welding, electroslag welding, gas welding, plasma arc welding, fusion welding, pressure welding, and brazing. The welding of sheet metal products is mainly arc welding and gas welding. Arc welding has the advantages of flexibility, mobility, wide applicability, and all-position welding; all equipment is simple, durable, and low maintenance costs. However, the labor intensity is large and the quality is not stable enough, which depends on the level of the operator. The temperature and nature of the gas welding flame can be adjusted. Because the heat source of arc welding is wider than the heat affected zone, the heat is not as concentrated as the arc, and the productivity is low. Therefore, in the sheet metal processing process, we must pay attention to the different process requirements according to the needs of the processing method.


To meet the processing requirements, the equipment must meet certain requirements. The large laser cutting machine can cut carbon steel, stainless steel and other materials, or laser cutting can be used. After the workpiece is processed, the section is neat, smooth and beautiful, and the size is accurate. . The process flow of sheet metal processing, according to the different materials of the product, the degree of processing of the product should also be considered. The plate parts of the punching machine are used to develop a large number of production, and the drawn expanded digits are used for process cutting and cutting. The cutting of the plate thickness and the production of the product enable the laser technology of sheet metal processing to realize the role of laser technology in the processing technology.


Numerical control technology has been widely used in sheet metal machine tools, which solves the problems of high precision, complex shapes, and large batches of parts in sheet metal processing. As sheet metal processing products are widely used in many industries such as aerospace, railway transportation, environmental protection equipment, air-conditioning appliances, tobacco machinery, packaging and printing, engineering machinery, textile machinery, and household appliances. Sheet metal processing also requires more high-skilled workers to operate, and good equipment and excellent employees can produce good products.
