Abstract

The utility model relates to lifting hook pliers for a ring forging piece, which comprises two L-shaped bent pliers arms. The bending positions of the two pliers arms are connected through hinge shafts II, the upper ends of the pliers arms are respectively provided with the hinge shafts II, the lower ends of the pliers arms are clamping portions, the hinge shafts II are connected with a hinge shaft I through connecting rods, and a hanging ring is arranged on the hinge shaft I. The lifting hook pliers for the ring forging piece is suitable for carrying a forged ring forging piece to the next working place to be processed, simple in structure and convenient to operate.

Description

A kind of ring rolling spare clamps with suspension hook

Technical field

The utility model relates to a kind of suspension hook pincers, is meant that especially a kind of ring rolling spare clamps with suspension hook.

Background technology

In the forging process of ring rolling spare; Need be carried to next work place to ring rolling spare after forging finishes handles; And just forged the ring rolling spare that finishes because temperature height and quality are heavy, and be inappropriate for a dead lift, carry out handling so need hang with instrument; This just needs a kind of special hanging use anchor clamps, and present hang too complicated and be not easy to operate with the most structure of anchor clamps.

The utility model content

The utility model technical matters to be solved is: a kind of operation of being convenient to is provided, and forging simple in structure clamps with suspension hook.

For addressing the above problem; The technical scheme that the utility model adopts is: a kind of ring rolling spare clamps with suspension hook, comprises the tong arm of two L types bending, and two tong arm bending parts connect through the hinge III; The upper end of tong arm is respectively equipped with the hinge II; The lower end of tong arm is a holding part, and the hinge II is connected with the hinge I through pipe link respectively, and the hinge I is provided with link.

It is outer hook-shaped that the holding part afterbody of said tong arm is.

The beneficial effect of the utility model is: above-mentioned suspension hook wrench structure is simple, be convenient to operation, and use cost is low, and this suspension hook pincers afterbody is outer hook-shaped, and clamping is more firm, thereby has strengthened safety performance, has improved work efficiency.

Description of drawings

Fig. 1 is the structural representation of a kind of ring rolling spare of the utility model with the suspension hook pincers;

Among the figure: 1, hinge II, 2, pipe link, 3, link, 4, the hinge I, 5, tong arm, 6, the hinge III, 7, holding part.

The specific embodiment

Through specific embodiment a kind of forging of the utility model is done further to describe in detail with the suspension hook pincers below.

As shown in Figure 1, a kind of ring rolling spare clamps with suspension hook, comprises the tong arm 5 of two L types bending; The bending part of two tong arms 5 connects through hinge III 6; The upper end of tong arm is respectively equipped with hinge II 1, and the lower end of tong arm 5 is a holding part 7, and hinge II 1 is connected with hinge I 4 through pipe link 2 respectively; Hinge I 4 is provided with link 3, and it is outer hook-shaped that holding part 7 afterbodys of said tong arm 5 are.

The principle of work of the utility model is: during handling ring rolling spare, above-mentioned suspension hook is clamped the centre hole that the lower end places ring rolling spare, link 3 is connected with loop wheel machine; Stretching link 3, link 3 upward movements are because of two pipe links 2 are connected through hinge II 1 with two tong arms 5 respectively; When link 3 upward movements, hinge II 1 drives pipe link 2 respectively and comes closer with tong arm 5 upper ends, because tong arm 5 is the L type; When tong arm 5 upper ends came closer respectively, the holding part 7 of its lower end outwards moved respectively ring rolling spare is grasped, and its holding part 7 afterbodys are outer hook-shaped; Thereby holding ring forging that can be more firm, thus safety performance strengthened, improved work efficiency.

The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.

Claims
