Description

A kind of forging die used for forging automobile steering arm

technical field

The utility model relates to a forging die, in particular to a forging die used for forging an automobile steering arm.

Background technique

Automobile steering arm is an important safety component in automobile steering system, and every automobile uses two symmetrically shaped automobile steering arms. The steering arm of a car plays the role of connecting the wheel and the body. During the driving process of the car, the steering arm is subject to frequent and complex variable stresses. Once damaged, it may cause serious traffic accidents. relatively high.

At present, automobile steering arms are mainly processed by die forging with forging dies, and in production, they are usually forged individually, that is, one pair of forging dies can only forge one automobile steering arm. Such a mold structure is that a curved billet groove and a final forging groove are arranged on a mold. Therefore, for the manufacture of a pair of symmetrically shaped automobile steering arms, two pairs of forging molds are required for forging respectively. This forging method not only reveals the production efficiency, but also wastes mold materials.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a forging die for forging an automobile steering arm, so that the forging die can be used to process two symmetrically shaped automobile steering arms.

In order to achieve the above object, the utility model adopts the following technical solutions:

A forging die for forging a steering arm of an automobile is characterized in that it includes: an upper die plate with a punch at the bottom, and a lower die plate with a die set at the top, wherein two dies are formed between the punch die and the die It is used for forging the die chamber of the steering arm of the automobile, and the two die chambers are symmetrically distributed about the center line of the forging die.

Further, in the forging die for forging the steering arm of an automobile provided by the utility model, it may also have such a feature: the punch includes two bosses, the die includes two grooves, and each boss respectively A corresponding groove forms a cavity.

Further, in the forging die used for forging the steering arm of the automobile provided by the utility model, it may also have such a feature: two bosses are symmetrically distributed about the center line of the punch, and two grooves are about the center line of the die. The center line is symmetrically distributed.

Further, in the forging die used for forging the steering arm of the automobile provided by the utility model, it can also have such a feature: the side wall of the upper template is provided with a curved upper groove, and the side wall of the lower template is provided with a curved lower groove. and the curved upper groove and the curved lower groove form a curved groove.

The positive effect that the utility model has on the above-mentioned basis is:

The forging die provided by the utility model forms two symmetrical mold cavities between the punch and the concave die, so that a pair of automobile steering arms can be forged on a pair of forging dies. Not only greatly improves the production efficiency of the steering arm of the automobile, but also saves the mold material and reduces the mold changing time.

Detailed ways

In order to make the technical means realized by the utility model, creation features, reach purpose and effect easy to understand, the forging die provided by the utility model is set forth in detail in the following embodiments in conjunction with the accompanying drawings.

The forging die provided in this embodiment is used for forging the automobile steering arm 10 as shown in FIG. 1 and FIG. 2 .

As shown in Figures 3 and 4, the forging die provided in this embodiment includes: an upper template 1 with a punch at the bottom, and a lower template 2 with a die at the top, wherein two dies are formed between the punch and the die. The die chamber is used for forging the steering arm of the automobile, and the two die chambers are distributed symmetrically about the center line of the forging die.

The male mold includes two bosses, the female mold includes two grooves (21, 22), and each boss and a corresponding groove (21, 22) respectively form a cavity.

The grooves 21 and 22 are distributed symmetrically about the center line of the die. Then, correspondingly, the two bosses are distributed symmetrically about the center line of the punch.

In addition, in the forging die provided in this embodiment, a curved upper groove is provided on the side wall of the upper template 1 , and a curved lower groove 23 is provided on the side wall of the lower template 2 accordingly. That is, a curved groove 3 is formed by the curved upper mold groove and the curved lower mold groove 23, through which two symmetrical automobile steering arms can be bent and made into billets.

The forging die provided in this embodiment forms two symmetrically shaped die cavities between the male die and the female die, so that a pair of forging dies can complete the forging of a pair of automobile steering arms. Not only greatly improves the production efficiency of the steering arm of the automobile, but also saves the mold material and reduces the mold changing time.

The above is only a preferred example of the utility model. Of course, the forging die involved in the utility model is not limited to the structure in this embodiment. For those skilled in the art, it should be able to realize The solutions obtained by equivalent replacements and obvious changes made in the contents of the illustrations shall all be included in the protection scope of the present utility model.
