Technological process:

(1) Use grinding wheel cutting machine to cut the material, turn the end face and fillet R5.

(2) The furnace temperature is (450 ± 10) ℃ and the holding time is 136min.

(3) Die forging and die forging equipment is 6300kN friction press. Firstly, the blank is flattened to h = 24mm on the upsetting table of the forging die, and then the blank is placed horizontally in the groove for die forging, and the under pressure is 2 ~ 3mm.

(4) The heating temperature is (450 ± 10) ℃ and the holding time is 30min (second fire).

(5) Die forging and pressing to dimension.

(6) The heating temperature is (450 ± 10) ℃ and the holding time is 10-15min.

(7) Hot edge

(8) Pickling shall be carried out according to the general pickling process.

(9) Heat treatment: quenching and artificial aging according to heat treatment process.

(10) Pickling shall be carried out according to the general pickling process.

(11) Forging repair

(12) forging inspection: 100% inspection of material grade, shape and surface quality; 100% hardness (HB ≥ 140); Low power inspection.

Matters needing attention:

(1) The pre forging process mainly includes blanking and heating. In the blanking process, the original blank is prepared according to the specifications and sizes required for forging, and the rust removal, surface defects removal, anti-oxidation and lubrication treatment should be carried out when necessary; The heating process heats the blank according to the heating temperature and production rhythm required by forging deformation.

(2) forging deformation process: plastic deformation of the blank is carried out on various forging equipment to meet the basic internal and external quality requirements of forgings. The process may include several processes.

(3) After forging deformation, the cooling process of forging is followed by forging deformation.
