1. a kind of processing technology of open type die cavity forging die working face, it is characterised in that step is as follows:

  • Step one:

    MachiningDie cavity, and the transition cavity surface (120) and end cavity surface (130) of the die cavity milled out are milled out on forging die base material (100)At grade, central cavity face (110) protrude from above-mentioned plane;

    Step 2:

    Pre-welding heat treatmentForging die base material (100) after machining is heat-treated;

    Step 3:

    Work surface build-up weldingThe transition circle segmental arc (222) of forging die working face (200) uses well word built-up welding unit (310) lattice built-up welding, forging die working face(200) middle part arc section (221) and end arc section (223) uses grid built-up welding unit (320) built-up welding;

    Step 4:

    Post weld heat treatmentThe forging die that built-up welding completes forging die working face (200) is heat-treated;

    Step 5:

    Digital control processing is polishedThe wlding for removing excess surface after welding is processed to forging die cavity, and polishing is carried out to working face and receives light.
