Description

a forging mold

technical field

The utility model relates to a die, in particular to a forging die.

Background technique

The car steering knuckle is one of the main parts of the car steering axle. When the car is running, it can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to bear the front load of the car and the variable impact load, support and Drive the front wheel to rotate around the kingpin to make the car turn.

At present, automobile steering knuckles are usually processed by die forging. Specifically, in production, the billet is usually made by free forging hammer, and then forged on the die forging hammer. This forging method requires the use of multiple forging equipment in stages Therefore, the production of automobile steering knuckles has the problems of scattered processes and relatively low production efficiency. Moreover, free forging blanks require a high level of operational skills for technicians, which can easily lead to the scrapping of automobile steering knuckle blanks.

Utility model content

In order to solve the above-mentioned problem of low forging efficiency in the automobile steering knuckle, the purpose of the utility model is to provide a forging die that can complete the forging process on the same forging equipment, thereby improving production efficiency.

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

A forging die is used for forging automobile steering knuckles, which has such features, including: a punch, and a concave die corresponding to the punch, wherein a billet cavity and a pre-forging die are formed between the punch and the concave die Chamber, and final forging die chamber.

Further, in the forging die provided by the utility model, it may also have such a feature: the cavity of the billet, the cavity of the pre-forging cavity, and the cavity of the final forging are arranged in the shape of "pin".

Further, in the forging die provided by the utility model, it can also have such a feature: the punch includes a first upper die cavity, a second upper die cavity, and a third upper die cavity, and the concave die includes a first lower die cavity , the second lower die cavity, and the third lower die cavity; the first upper die cavity and the first lower die cavity form the billet cavity, the second upper die cavity and the second lower die cavity form the pre-forging die cavity, and the third The upper die cavity and the third lower die cavity form the final forging die cavity.

Further, in the forging die provided by the utility model, it may also have such a feature: the convex die is installed at the lower end of the upper template, and the concave die is installed at the upper end of the lower template.

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

The forging die provided by the utility model forms a billet-making die chamber, a pre-forging die chamber, and a final forging die chamber between the punch and the die, so that the automobile steering knuckle can be completed on the same forging equipment. Pre-forging, and final forging processing, the process is concentrated. In addition, the forging die provided by the utility model can respectively perform billet making, pre-forging, and final forging processing on three automobile steering knuckles in one die forging process, thereby greatly improving the production efficiency of the automobile steering knuckles.

Detailed ways

In order to make the technical means, creative features, goals and effects of the utility model easy to understand, the following examples will specifically illustrate the forging die provided by the utility model in conjunction with the accompanying drawings.

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

As shown in Figures 3 and 4, the forging die in this embodiment includes: a punch, and a die corresponding to the punch, wherein the punch is installed at the lower end of the upper template 1, and the die is installed at the upper end of the lower template 2 .

A billet-making die cavity, a pre-forging die cavity, and a final forging die cavity are formed between the punch die and the concave die. Moreover, in order to reduce the volume and weight of the forging die as much as possible and to facilitate the forging operation, in this embodiment, the billet cavity, the pre-forging cavity, and the final forging cavity are arranged in the shape of a "product".

Specifically, the punch includes a first upper die cavity 11, a second upper die cavity 12, and a third upper die cavity 13, and the concave die includes a first lower die cavity 21, a second lower die cavity 22, and a third lower die cavity chamber 23. The first upper die cavity 11 and the first lower die cavity 21 form the blank forming die cavity, the second upper die cavity 12 and the second lower die cavity 22 form the pre-forging die cavity, the third upper die cavity 13 and the third lower die cavity 23 form the final forging die cavity.

The forging die provided in this embodiment forms a billet-making die chamber, a pre-forging die chamber, and a final forging die chamber between the punch and the die, so that the automobile steering knuckle can be completed on the same forging equipment. Pre-forging, and final forging processing, the process is concentrated. In addition, the forging die provided in this embodiment can respectively perform billet making, pre-forging, and final forging processing on three automobile steering knuckles in one die forging process, thereby greatly improving the production efficiency of the automobile steering knuckles.

Of course, the forging die involved in the utility model is not limited to the structure in this embodiment, and any equivalent modification and replacement of the utility model are also within the category of the utility model.
