The metal enclosure manufacturing industry specializes in producing and supplying a diverse range of cabinets designed to store and safeguard electronic equipment, network devices, servers, and related components. Enclosures not only serve a protective function for internal electronics but also emphasize aesthetic presentation to users. As a result, precision sheet metal processing of chassis and cabinets has emerged as a critical segment within process manufacturing.
Electrical panels typically comprise shells, doors, bottom plates, back plates, partitions, and other components. These are crafted from cold-rolled and hot-rolled steel plates, ensuring durability and structural integrity.
Hydraulic guillotine shearing machine process
- Material Procurement: Source sheet metal materials like cold-rolled steel plates or stainless steel plates, ensuring that the material quality meets required standards.
- Shearing Process: Place the sheet metal on the hydraulic guillotine shearing machine and cut it according to the design's specified dimensions and shapes. This ensures precise sizing and clean edges.
- Inspection: Visually inspect the sheared metal parts to confirm that edges are straight and angles are accurate.
CNC Turret Punching or Laser Cutting Process
- Preparation: Verify the design drawings with the sheared materials before commencing turret punching production. Ensure all specifications align.
- Punching and Cutting: For materials less than 3mm thick, the CNC turret punch can handle various punching, forming, and cutting tasks. For thicker materials, use traditional punching equipment for embossed holes, formed holes, or notches. A laser cutting machine can also handle standard flat holes.
CNC Press Brake Bending
- Preparation and Setup: Before bending, inspect the design drawings and select the appropriate tooling, bending program, and process. Plan the bending sequence to ensure precise dimensional relationships between bent surfaces.
- Bending Process: Perform bending according to specifications, ensuring dimensional accuracy.
- Quality Control: Conduct appearance and quality inspections. Make any adjustments or corrections as needed.
CNC Fiber Laser Welding Process
- Welding Process: After bending, the metal panels proceed to welding. Choose from arc welding, gas-shielded welding, or fiber laser welding.
- Laser Welding: Preferred for its ease of use, laser welding provides precise seams that require minimal finishing, resulting in aesthetically pleasing welds.
