At present, the common connection methods of sheet metal parts of the car seat back panel usually have a wire-wire, a wire-plate, a plate-wire-plate, and a plate-plate connection structure. For steel wire-steel and steel wire-plate connection structures, arc welding is usually adopted; for board-wire-plate and board-plate connection structures, spot welding or laser welding is usually adopted.
Automotive sheet metal partsProcessing is the processing of plates of uniform thickness, and the processing technology is different from that of hardware. The main production steps are cutting, punching, folding, welding and bonding, and the hardware naturally includes sheet metal. The stamping process can be roughly divided into two categories: separation process and forming process (also divided into bending, drawing, and forming). The separation process is to separate the stamping part and the blank along a certain contour line during the stamping process. At the same time, the quality of the separated section of the stamping part must meet certain requirements; the forming process is to make the stamping blank undergo plastic deformation without damage. And transformed into the required finished shape, but also should meet the requirements of dimensional tolerances.
According to the temperature during stamping, there are two methods: cold stamping and hot stamping. This depends on the material’s strength, plasticity, thickness, degree of deformation and equipment equipment equipment capabilities, etc., while the original heat treatment state and use conditions of the material should be considered.
Sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing, punching/cutting/compounding, folding, welding, riveting, splicing, forming (such as car body), etc. Its notable feature is the uniform thickness of the same part. Generally speaking, the basic equipment includes shearing machine, CNC punching machine, plasma, water jet cutting machine, composite machine, bending machine and various auxiliary equipment such as: decoiler, leveling machine, deburring machine, spot welding machine, etc.
