The sheet metal processing process should be careful to avoid waste. In sheet metal processing raw materials are the basis and one of the cost charges, so care should be taken to avoid waste when accounting for them.
In the whole process of sheet metal processing, according to the basic processing methods of sheet metal, the following are used: undercutting, sheet metal bending, lashings, forming and welding. According to the different processing methods, the material can be divided into general punching, digital punching, shearing machine cutting, fibre optic laser cutting and wind cutting, because the processing methods are different, the processing performance of the material is also different.
The key to sheet metal parts undercutting methods for CNC machine tools and fibre laser cutting. Fiber laser cutting advantage is processing to the plate only thin thickness large, laser cutting product workpiece appearance design faster, processing dexterity, defect is unable to process forming, mesh parts are not suitable for processing with this method, processing costs increase. The key to the welding process are electric arc welding, electroslag welding, gas welding, low temperature plasma argon arc welding, fusion welding, work pressure welding, fibre welding.
Sheet metal parts products electric welding welding key for electric arc welding, gas welding. Electric arc welding has the advantages of handy, mobility, universal scope of application, can carry out all bits of electric welding welding; all machine and equipment simple, good durability, maintenance fee inferior. However, the labour efficiency is large, the quality is not smooth enough, the decision is made on the level of the operator. Gas welding flame temperature and characteristics can be adjusted, and argon arc welding heat original pressure than the thermal hazard area wide, heat generation than electric solitary centralization, low production efficiency. Therefore, in the whole process of sheet metal processing, we must pay attention to the different processing technology regulations according to the processing method.
Sheet metal processing factory production process, according to the raw materials of the product is not the same used raw materials but also take into account the processing level of the product, the use of punching CNC lathe of the board only the parts for a large number of production and manufacturing, will be made to carry out the processing process of a number of cutting generally used to cut the thickness of the board, and then carry out the production and manufacturing of the product, so that the sheet metal processing of laser equipment can be completed in the technical nature of the processing of the laser equipment to give full play to the effectiveness.
CNC machining technology in sheet metal parts CNC lathe has been widely used, it has solved the sheet metal processing in the existence of parts of high precision, look complicated, large quantities of large and other difficulties. Along with the sheet metal processing products in aerospace, high-speed railway, environmental protection machinery, central air conditioning household appliances, tobacco machinery, printing and packaging, engineering machinery and equipment, textile equipment, home furniture and many other fields of extensive use. Sheet metal processing must also be carried out by a large number of high-tech workers to carry out the actual operation, excellent machinery and equipment coupled with technical professional staff to produce and manufacture excellent products.
