Introduction
Metal plastic processing is a process of forming metal thin wall parts that have complex shapes and a variety of performances through stamping, bending, punching, welding and other processes. Generally, metal plastic processing materials are metal materials, generally with iron and aluminum materials, but also can be stainless steel, copper and other materials, according to the actual product processing requirements.
Processing techniques
1. Stamping
Stamping is the process of using a punch to press the sheet metal into a shape according to the pre-designed shape, shape and size of the mold. It is a process of forming parts after the material is placed in the mold. The stamping parts processed by this process have the advantages of high precision, strong rigidity, uniform thickness and good surface quality.
2. Bending
Bending is a process of continuously deforming the sheet material to form arc-shaped parts or components by means of a certain mold or tooling. Bending is a thermal processing process that requires a certain pressure, each bend requires a gradient some different forces to hold the material down. The processed parts generally have the characteristics of uniform clamping force, reasonable bending shape and high precision.
3. Punching
Punching is the process of extruding and forming parts of a certain shape and size through the mold cavity in a certain cutting force. Punching is the basic forming process of plastic processing. The punching method can be divided into three types: single-operation punching, multi-station punching and continuous punching. Continuous punching is a punching method for forming a large number of similar parts at one time.
4. Welding
Welding is a process in which parts and components are processed by heat and plastic deformation. Generally, the heat is generated by electrical spark, mechanized heat, laser and other heat sources, which makes the individual parts of the parts to be processed liquefied, and then completed by a tooling mold with a certain pressure. Welding is a key technology in the production of plastic parts, and generally requires higher accuracy than other plastic processing methods.
Advantages and application of metal plastic processing
Metal plastic processing has the following advantages: first, with high precision and good quality; second, it can be used for parts with complex shapes; third, it can be used for large-scale production of parts; fourth, it can be used for welding of thicker materials; fifth, it can be used for material savings and cost reduction; sixth, it can be used for processing of non-metal materials.
Metal plastic processing technology is widely used in modern industry and is one of the most widely used processing technologies. It is mainly used for the processing and assembling of frame parts, such as automobiles, bicycles, electric vehicles, motors, household appliances and electric tools, etc. It is also used for the processing of small parts, such as batteries, small electromechanical parts and shells, as well as for the manufacturing of civil and industrial pressure vessels.
Conclusion
Metal plastic processing is a process of forming complex shapes and a variety of performances through stamping, bending, punching and welding. Its main advantages are its high precision, good quality, saving materials, cost reduction and its wide application range. Metal plastic processing technology is an important technology in the current industrial production, and plays an important role in many fields.
