The invention discloses a bush
forging technology, including the following steps of: 1, chamfering one end of a steel
ingot workblank, pressing feeder head at the other end to form pincers handles,
cutting off excessive length,
cutting water gap, and burring; 2, vertically placing the workblank into an upsetting plate part in a mold; 3, taking out the mold,
punching a through hole by using a punch; 5, leveling the end face, penetrating a rod into an inner hole to press to be hexagonal and
rounding, clearing angles, and enlarging the hole to the designed size; 6; leveling the end face, penetrating the rod again, pressing the small end to be hexagonal and drawing out, chamfering and
rounding, leveling the end face, and slight enlarging the inner hole again to the designed size; 7, leveling and reshaping; 8, thermal
processing after the
infrared measured size is qualified. The bush
forging technology has the advantages of being simple and convenient in technology, according to the bush
forging technology, qualified product can be directly obtained by forging, the tissue fibers of the product is prevented from being damaged by turning
processing, the service life is improved, and meanwhile, the
processing amount is reduced, the material is saved, and the cost is lowered.
