Sheet metal fabrication is a common metalworking technique that is widely used in a variety of industries. Taking Yuehuihao as an example, the process of sheet metal processing of charging pile shell includes the following steps:
The first step is sheet metal blanking. This step usually uses techniques such as laser cutting or CNC stamping to cut the sheet metal into parts of the desired shape and size. Laser cutting is achieved by shining a high-energy laser beam on a metal plate, causing it to melt or vaporize locally. CNC stamping is the precise stamping operation through CNC machine tools to obtain parts of the desired shape and size.
The second step is to bend the shapes and parts of the charging pile shell. This step is usually carried out using a press brake, where the cut sheet metal is bent at the desired angle and shape. During the bending process, care needs to be taken to protect the metal surface to avoid scratches or deformations.
The third step is to weld. This step is to assemble and weld the bent parts to form a complete structure. In the welding process, it is necessary to pay attention to the welding quality and accuracy to avoid false welding, missing welding or welding deformation.
The fourth step is to polish. This step is to remove impurities such as burrs, weld nodules, and oxide scale generated during the welding process, making the surface smoother and smoother. During the sanding process, care needs to be taken to use suitable sandpaper or abrasive tools to avoid scratches or damage to the metal surface.
The fifth step is pre-processing. This step is to ensure the cleanliness and adhesion of the metal surface in preparation for subsequent painting and assembly. Pre-treatment typically includes operations such as degreasing, rusting, phosphating, and passivating to remove grease, rust, and other impurities from metal surfaces.
The sixth step is to spray. This step involves spraying one or more layers of paint on the metal surface to protect and decorate the metal surface. In the process of spraying, it is necessary to pay attention to factors such as the selection, thickness and uniformity of the coating to avoid uneven coating, blistering or falling off.
The seventh step is to assemble it. This step is to assemble and debug the sprayed parts to make them a complete charging pile shell. During the assembly process, it is necessary to pay attention to the coordination and accuracy of each component to ensure the stability and reliability of the charging pile.
In short, the process of sheet metal processing of charging pile shell includes steps such as blanking, bending, welding, grinding, pre-treatment, spraying and assembly. Each step has its own specific requirements and precautions, which need to be operated in strict accordance with the process requirements. At the same time, in order to improve production efficiency and product quality, it is also necessary to use advanced equipment and technology to support and guarantee.
