| titleOfInvention | A kind of piston cold extruding formation process |
| abstract | The invention discloses a kind of piston cold extruding formation process, this technique comprises the steps: that by raw material turning blanking be the blank meeting size；Being annealed blank processing, annealing temperature is 410～420 DEG C；Blank is carried out extruding front surface lubricated；Adopt extruder that blank is carried out Compound Extrusion, obtain the product meeting size that top is the both wings that thin-wall circular is cup-shaped, bottom is middle bifurcated；The product meeting size is carried out Quenching Treatment and timeliness, and hardening heat is 495 ± 5 DEG C.Adopting this technique can improve stock utilization, stock utilization reaches more than 80%, and percent defective is less than 0.5%. |
