In the whole process of sheet metal processing, according to the basic processing method of sheet metal, the following materials are used: sheet metal bending, deep drawing, forming and electric welding. According to different processing methods, blanking can be divided into ordinary punching, digital punching, shearing machine cutting, optical fiber sheet metal cutting and air cutting. Due to different processing methods, the processing performance of blanking is also different.
The key to the sheet cutting method is CNC machine tool and fiber laser cutting. The advantage of fiber laser cutting is that the processing board is thin and thick. The appearance design speed of laser cutting products is faster and the processing is convenient. The disadvantage is that it cannot be processed and formed. Mesh parts are not suitable for machining by this method, and the machining cost increases. Key welding processes include arc welding, electroslag welding, gas welding, low temperature plasma argon arc welding, fusion welding, working pressure welding and fiber welding
The key to electric welding of sheet metal products is arc welding and gas welding. Arc welding is convenient, flexible and widely applicable, and can be welded in all positions; all machines and equipment have the advantages of simplicity, durability and low maintenance costs. However, the labor efficiency is high, the quality is unstable, and the decision-making depends on the level of the operator. The temperature and characteristics of the gas welding flame can be adjusted. Compared with the constant pressure heat source of argon arc welding, its thermal hazard range is wider, the heating capacity is smaller than that of arc welding, and the production efficiency is lower. Therefore, in the whole process of sheet metal processing, we must pay attention to different processing technology regulations according to the processing method.
According to the production process of the sheet metal processing manufacturer, according to the different raw materials of the product, the raw materials used should also take into account the processing level of the product, use the plate parts of the CNC lathe for mass production, and cut the produced parts during the processing process. It is generally used to cut the thickness of the sheet, and then carry out the production and manufacture of the product. The laser equipment used for sheet metal processing can complete the functions of the laser equipment in the processing technology.
CNC machining technology has been widely used in sheet metal CNC lathes. It solves the problems of high precision, complex shape and large batch in sheet metal processing. With the wide application of sheet metal processing products in aerospace, high-speed railway, environmental protection machinery, central air-conditioning appliances, tobacco machinery, printing and packaging, construction machinery and equipment, textile equipment, household furniture and many other fields. Sheet metal processing must also be carried out by a large number of high-tech workers. Only with excellent mechanical equipment and professional technicians can we produce excellent products.
