As the effect of sheet metal chassis is very critical, the processing of sheet metal chassis is very critical and rigorous. Only by fully mastering all processes involved and complying with relevant regulations can we better ensure that the processing quality of sheet metal chassis meets the requirements. What processes will be involved in the processing of sheet metal chassis?
1. Assembly process. In the processing of sheet metal chassis, the common assembly methods are ground pattern assembly, copy assembly, vertical assembly, column assembly and inverted sentence assembly.
2. Cutting process. For the blanking process of sheet metal chassis processing, the key is to blanking the materials according to the drawings that have completed the construction setting out. The usual cutting methods are: manual cutting, mechanical equipment cutting, blanking parts processing, CNC flame cutting, low-temperature plasma oxygen cutting, etc. Cutting can be selected according to different technical standards, large-scale scale scale and cost. With different cutting methods, there will be different choices for cutting and processing of leftover materials according to the drawings.
3. Forming process. Shandong sheet metal manufacturers remind us that the forming process is a very core stage in the processing of sheet metal chassis. Design scheme specification plays an extremely important role in improving processing efficiency, product quality and cost control. The forming process includes:
Human body forming, mechanical equipment forming, top pressing forming, blasting, etc. Among them, manpower is a professional skill that traditional sheet metal workers must master; Mechanical equipment forming is now a particularly common process, bending equipment and molds to complete the forming of sheet metal workpiece.
During the processing of sheet metal chassis, pay attention to the following aspects:
During bending, the production and processing of the sheet metal chassis shall be carried out in accordance with the specifications on the engineering drawings. During the processing of sheet metal chassis, the surface treatment shall be carried out after bending, riveting and other processes. Different materials have different surface treatment methods. After the production and processing of cold rolled steel plate, the surface electroplating process is generally carried out. Paint spraying is not required after electroplating. Clean, degrease and paint the substrate surface. The stainless steel plate can be finished with metal drawing before bending, but it has not been sprayed. If spraying is required, roughening is required; Choose different air oxidation base colors for different colors of paint.
During the processing of sheet metal chassis, it is usually necessary to realize blanking before entering the next process. Different workpieces enter the corresponding process according to the requirements of production and processing. There are bending, riveting, counter attack, welding, flashing, height difference, etc. Sometimes the bolts or studs should be bent once or twice and then pressed tightly, with the flash and height difference of the mold shell in the middle. Production and processing must be considered first to prevent other technological processes from interfering with diseases after production, and the required production and processing cannot be carried out. If the upper cover or lower shell has a hook and cannot be butt welded after bending, it must be produced and processed before bending.
In general, we can see that the processing of sheet metal chassis generally involves three processes: assembly, blanking and forming. For more information, you can follow our website www.jrjmockup COM, check the information, contact us to meet the purchase demand!
