Abstract
The utility model discloses a straight arm forged piece which comprises a first end junction part and a second end junction part, wherein the first end junction part and the second end junction part are connected through a straight arm part; the first end junction part is provided with a first borehole end part through a bent arm part. The straight arm part protrudes between the first end junction part and the second end junction part to form a second borehole end part and a third borehole end part. Bowl-shaped grooves are arranged on both upper and lower surfaces of the first end junction part and the second end junction part, wherein the axes of the first end junction part and the second end junction part and the borehole axes of the second borehole end part and the third borehole end part are positioned in the same plane; an included angle of 72 degrees is formed between the borehole axis of the first borehole end part and the plane; an included angle of 11 degrees is formed between the axis of the bowl-shaped groove of the second end junction part and the borehole axis of the third borehole end part; and the axis of the bowl-shaped groove of the first end junction part is parallel to the bore axes of the second borehole end part and the third borehole end part. The technical scheme has the advantages that the structure is reasonable, the straight arm forged piece is convenient to process and manufacture and is reliable to use, the cost performance is high, and the like.
