CN201400522Y - Free forged lifting hook - Google Patents

Abstract

The utility model relates to a free forged lifting hook, which is mainly used for hoisting. The shape of the lifting hook is that the middle part is a long and thin bent cylinder (1), the two ends areflat blocks (2), and the middle of the flat blocks (2) are processed with round holes (2.1). The lifting hook belongs to the important part when in work and needs to bear heavier load; the long and thin bent cylinder in the middle part can ensure the weight of the lifting hook at the left side and the right side to be consistent, so that the lifting hook can not turn over when in use. Therefore,the free forged lifting hook can bear heavier load.

Description

The suspension hook that open die forging is shaped

(1) technical field

The utility model relates to a kind of suspension hook.Belong to the suspender technical field.

(2) background technology

Before the utility model was made, it is hook-shaped that suspension hook in the past all is.It can not bear the greater weight load.Cause traditional hook-shaped suspension hook not to be suitable for.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, the suspension hook that provides a kind of open die forging that can bear big mass loading to be shaped.

The purpose of this utility model is achieved in that the suspension hook that a kind of open die forging is shaped, and is the elongate cylinder of bending in the middle of being shaped as of described suspension hook, and two ends are flat, and described flat centre is processed with circular hole.

Suspension hook belongs to vitals when work, need to bear the greater weight load.Middle curved elongate cylinder can guarantee the right and left weight unanimity of suspension hook, in use unlikely generation overturning phenomenon.Therefore the suspension hook of the utility model open die forging shaping can bear big mass loading.

(4) description of drawings

Fig. 1 is the overall structure scheme drawing of the suspension hook of the utility model open die forging shaping.

Among the figure: elongate cylinder 1, flat 2, circular hole 2.1.

(5) specific embodiment

Referring to Fig. 1, the suspension hook that open die forging that the utility model relates to is shaped is the elongate cylinder 1 of bending in the middle of being shaped as of this suspension hook, and two ends are flat 2, is processed with circular hole 2.1 in the middle of described flat 2.

The manufacturing process of the utility model suspension hook is as follows:

Forging into earlier two ends has upright piece, and the centre is the solid forging crude green body of elongate cylinder, designs a cover bending die again, counterdie is made two perpendicular squares, square of patrix, and an end is processed into semicircle, find crude green body accurately center and be placed on the counterdie, by on be molded into, make two ends K/UP moulding.

Claims (1)

1, the suspension hook that is shaped of a kind of open die forging is characterized in that in the middle of being shaped as of described suspension hook be the elongate cylinder (1) of bending, and two ends are flat (2), are processed with circular hole (2.1) in the middle of described flat (2).
