The invention belongs to the technical field of track link section machining, and particularly relates to a machining process of a large-size forging track link section, and the track link section. The machining process comprises the following machining steps that S1, annealing treatment is conducted, specifically, annealing equipment is prepared; S2, blanking is conducted; S3, phosphorization andsaponification treatment are conducted; S4, die forging forging-pressing forming is conducted, specifically, a blank is placed on a track link section die, the die is fixed to large forging equipment, the forging pressure of the forging equipment is greater than 10000 tons, during forging, the blank is heated to be within the range of 1200+/-25 DEG C, and the center and surface temperature difference is less than or equal to 50 DEG C; S5, punching and trimming are conducted; S6, quenching is conducted, specifically, the large-size forging track link section is quenched, continuous induction quenching is conducted, the continuous scanning heating speed is 350-380 mm/min, tap water serves as a quenching medium, and the water temperature is 20-40 DEG C; and S7, tempering is conducted. The large-size forging track link section is good in surface quality, good in mechanical performance, and not prone to brittle failure.

    本发明属于链轨节加工技术领域,尤其一种大尺寸锻造链轨节的加工工艺及链轨节,包括以下加工步骤:S1:退火处理,准备退火设备;S2:下料;S3:磷化皂化处理;S4:模锻锻压成型,将胚料放在链轨节模具上,模具固定在大型锻造设备上,锻造设备的锻造压力大于10000吨,在锻造时,对胚料加热,坯料要加热到1200±25℃的范围内,且心表温差≤50℃;S5:冲孔切边;S6:淬火,将大尺寸锻造链轨节淬火处理,进行连续感应淬火,连续扫描加热速度350‑380mm/min,淬火介质为自来水,水温20‑40℃;S7:回火;本发明的大尺寸锻造链轨节表面质量好,机械性能好、而且不易脆断。
