What are the precautions for the shell of sheet metal processing equipment?

1、 Precautions for Preparation Before Processing

Drawing verification: Carefully confirm the dimensions, hole positions, and surface treatment requirements marked on the drawing to avoid rework in the future.
Material selection: Select the corresponding material according to the usage scenario, such as 304/316 stainless steel for corrosive environments and aluminum alloy for lightweight scenarios.
Equipment adaptation: Based on the shape, size, and material characteristics of the casing, select corresponding processing equipment such as shearing machines and CNC bending machines.

2、 Core considerations during the processing

Cutting process: Match the cutting edge with the workpiece to avoid cutting vibration and thermal deformation, ensuring a straight and burr free cut.
Bending process: Determine the mold specifications in advance, adapt the material strength and toughness, and avoid parts fracture caused by too small bending radius.
Welding process: Select appropriate welding techniques such as TIG/MIG, clean the welding area before welding, control parameters to avoid burn through and porosity defects.
Precision control: Control the machining tolerance throughout the process to ensure that the flatness, perpendicularity, and other indicators of the shell meet the acceptance standards.

3、 Post processing and quality control precautions

Surface treatment: Thoroughly clean the surface of the shell before spraying and electroplating to ensure coating adhesion and appearance quality.
Finished product inspection: Verify assembly smoothness, sealing performance, electromagnetic shielding and other indicators to ensure compliance with design requirements.
Structural optimization: Make rounded corners and reserve reasonable heat dissipation holes to avoid sharp scratches and poor heat dissipation.

4、 Safety and operation precautions

Personnel protection: Wear goggles, earplugs, and protective clothing during operation, and ensure proper ventilation and dust removal on site.
Equipment maintenance: Regular maintenance of processing equipment, timely troubleshooting, and ensuring processing stability.
On site management: Keep away from flammable materials, equip with fire-fighting equipment, and keep the work area clean and free of oil stains.
