3. a kind of oil fracturing according to claim 1 pumps forging process method, it is characterised in that: in the step (1) Rare earth is quality proportioning lanthanum 10%, cerium 30%, praseodymium 20%, samarium 10%, europium 10%, gadolinium 10%, terbium 10%.
4. a kind of oil fracturing according to claim 1 pumps forging process method, it is characterised in that: step (4) heat Processing includes: first normalizing: workpiece being heated to 750 DEG C of heat preservations 15-20 minutes, takes out in air or sprays water from furnace, spray Mist or quenching are to 200-300 DEG C;Normalizing again: being heated to 850 DEG C of heat preservations 15-20 minutes for workpiece, takes out from furnace In air or water spray, spraying or quenching are to 200-300 DEG C;Normalizing three times: workpiece is heated to 950 DEG C of heat preservation 15-20 points Clock takes out in air from furnace or water spray, spraying or quenching is to 200-300 DEG C;
Oil quenching: by workpiece be heated to 920 ° of c carry out oil quenchings taken out from furnace in air or water spray, spraying or quenching to 200-300℃;Workpiece is heated to 780 ° of c oil quenchings to take out from furnace in air or water spray, spraying or quenching to 200- 300℃;
High tempering: after part oil quenching, 500~650 DEG C are heated to, 20-30 minutes are kept the temperature, to reduce by 20 DEG C per minute Speed is cooled to room temperature.
5. a kind of oil fracturing according to claim 1 pumps forging process method, it is characterised in that: described on forging surface Before sputtering, successively forging surface is cleaned by acetone, dehydrated alcohol and deionized water.
