Q: What are the key stamping process parameters for DC04?
A: Recommended blanking clearance is 6%–8%, elongation coefficient ≥0.65, and blank holder force is moderate; preheating to 60–80℃ before deep drawing can improve formability.
Q: What problems are prone to occur during DC04 stamping?
A: Wrinkling, cracking, springback; Countermeasures: Optimize die corner radius, adjust blank holder force, use draw beads, and control material thickness uniformity.
Q: Can DC04 be slitting and leveling?
A: Yes; slitting width ≥100mm, leveling accuracy according to GB/T 708, avoid edge burrs and deformation.
Q: What are the bending radius requirements for DC04?
A: Minimum inner bending radius R ≥0.5t (t is thickness) at room temperature to avoid cracking; R ≥1.0t for high surface finish requirements.
Q: What are the machinability properties of DC04?
A: Suitable for laser cutting, plasma cutting and CNC punching. The tool rake angle is 15°–20° and the cutting speed is 100–150m/min.
