Dongguan sheet metal processing factory: Introduction to sheet metal chassis processing _ hardware shell processing refers to the general term for Shell Processing of five metal materials: gold, silver, copper, iron and tin. Hardware is the mother of industry and the foundation of national defense. The products produced by hardware materials are usually divided into two categories: big hardware and small hardware. Big hardware refers to steel plates, steel bars, flat iron, universal angle steel, slot iron, I-iron and various types of steel materials, hardware is building hardware, tin, lock nails, wire, steel wire mesh, wire scissors, Home Hardware, all kinds of things and so on. Sheet metal chassis processing refers to the technology of processing uniform thickness plates. Sheet metal chassis processing is fundamentally different from hardware, mainly in the production steps of cutting, punching, folding, welding and sticking. The hardware side naturally contains sheet metal and various sheet metal parts. Stamping is the most commonly used method in sheet metal chassis processing. Stamping technology is generally divided into two categories: separation process and forming process. 1. The separation process is to separate the stamping parts and blanks along a certain contour line during the stamping process, and the quality of the separated sections of the stamping parts must also meet certain needs, these needs are all determined by the needs of the previous customers. 2. The forming process is to make the stamping blank plastic deformation without damage and convert it into the required product shape, which should also meet the needs of scale tolerance and other aspects. Sheet metal is a comprehensive cold processing technology for metal sheets, including shearing, punching/cutting/compounding, folding, welding, riveting, splicing, forming, etc. Its remarkable feature is the same part thickness together. Generally speaking, the basic equipment includes shearing machine, numerical control punching machine, plasma and water jet cutting machine, composite machine, bending machine and various auxiliary equipment such as unwinding machine, leveling machine, depilation machine, spot welding machine, etc.
