The invention discloses a whole fiber copying forging forming method of a multi-jaw member, and belongs to the technical field of forging. The problems that large-scale multi-jaw members have poor integral performance, jaw root parts are prone to cracking, and the quality of the surface is poor in the prior art are solved. The whole fiber copying forging forming method of the multi-jaw member comprises the following steps that S1, a lifting hook forging piece drawing is drawn; S2, a blank material is subjected to heating and upsetting; S3, sectioning and forging are carried out; S4, drawing out forging is carried out; S5, parallel leveling and upsetting are carried out; S6, a forming ring body is placed on the blank material and centering is carried out, and the forming ring body is pressed down; S7, the forming ring body after pressed down and the blank material are both lifted to a lower mould, and the forming ring body is pressed down again to obtain U-shaped bending and a middle cone; and S8, a punch is placed at the upper end of the middle cone and centering is carried out, and punching operation is carried out to obtain a lifting hook forging piece. The whole fiber copying forging forming method of the multi-jaw member is suitable for the preparation of the large-scale multi-jaw members with 3000 tons and more than 3000 tons.
