This is a production line designed for Harman. The overall design adopts design techniques such as wrapping and stacking.
Key Process--
Laser cutting: high precision hole, suitable for special-shaped contour.
CNC bending: the use of multi-tool sequence programming, to achieve complex bending (such as Z-shaped structure).
Riveting/pressure riveting: instead of welding, avoid deformation (such as nut column pressure riveting process).
Sheet Metal Design Material--
Cold rolled steel sheet (SPCC): low cost, suitable for internal structural parts (thickness 1.5mm).
Galvanized sheet (SECC): Anti-rust, used in humid environments.
Aluminum alloy (6061-T6): Lightweight, corrosion resistant, locally applicable.
