with the current social development, the application of sheet metal processing is becoming more and more common, and the design concept of sheet metal has become a key stage in the whole process of commodity development and design. every mechanical engineer stipulates that the design concept method of sheet metal must be mastered skillfully, this promotes the design concept of sheet metal parts can not only consider the role of goods and appearance and other hardware configuration provisions, but also promote the metal mold production and manufacturing methods are simple, need to reduce the cost.

sheet metal has the characteristics of light weight, high compressive strength, electrical conductivity (can be used as magnetic shielding material), low cost, good scale burning characteristics, etc. it has been widely used in electronic and electrical, communication, automobile industry, medical machinery and other industries, for example, in the main chassis, mobile phones, MP3, speakers, sheet metal is an indispensable composition.

various difficult problems and reasons in sheet metal processing and stamping parts processing 1. burrs: the burrs caused by the lower position of the thick steel plate disconnection surface are taken as the standard, when the aspect ratio of the burr is about 0.3mm, the copper powder generated will destroy the grinding tool and cause unevenness. 2. The broken pipe material will or may wrinkle the edge: the guiding roller of the unwinder line will cause the wrinkle scene caused by the gap between the guiding roller on the grinding tool, which is caused by the tenacious balance of the pipe material. 3. Drag print: caused by the drag of the roller, and most of them are generated when they suddenly terminate or accelerate. 4 Scratches: The key reason for causing scratches on parts is that sharp scars on abrasive tools must have metal dust falling into abrasive tools. The countermeasures to avoid scratches are to sharpen scars on abrasive tools and eliminate metal dust. 5. Concave-convex: abnormal protrusions or dents on the surface of the material are caused by the infiltration of dirt (iron pins and dust) into the unwinder line. Stainless steel sheet metal processing. 6. Bottom cracking: The key reason for the bottom cracking of the parts is that the plastic deformation of the raw material is weak or the grinding tool hemming strip is too tight to be extruded. The countermeasures are to replace the raw material with good plastic deformation or release the hemming strip under some pressure. 7. Roller printing: It is caused by cleaning the roller or feeding roller sticking dirt (generated by fixed pitch diameter), but under normal circumstances, it is only possible to remove the roller printing dirt on the steel plate. 8. Wrinkles on the outer wall: The key reason for the wrinkles on the outer wall of the parts is the insufficient thickness of the raw materials (the smaller allowable thickness is still thinner) or the axial force occurs during the installation of the upper and upper dies, resulting in a large gap on one side and a small gap on the other side. Its avoidance countermeasure is to disassemble and replace the raw materials in time or adjust the grinding tool again.

numerical control processing technology is applied to the numerical control lathe of sheet metal parts. numerical control processing technology deals with some difficult problems such as high precision, complicated appearance and large quantity of parts existing in sheet metal processing. cnc machine tool sheet metal parts cnc lathe, it contains cnc shearing machine, cnc machine fiber laser cutting, cnc machine tools, cnc machine bending machine, automatic welding machine, cnc flame cutting and other cnc lathe. Their use in manufacturing has further improved the ability of sheet metal processing, ensured the quality and production of sheet metal, and reduced the labor efficiency of workers much better. Sheet metal processing due to the technical, and more and more intelligent, production and processing of raw materials, but also more and more high precision.
