Technical Field

[0001] The utility model relates to a secondary molding die, in particular to a secondary molding die for a reinforcement plate of a front suspension bracket of an automobile, and belongs to the field of automobile parts production dies. Background Art

[0002] There are many kinds of auto parts. With the improvement of people's living standards, people's consumption of cars is increasing, and the market of auto parts is becoming larger and larger. In recent years, auto parts manufacturers have also developed rapidly. The suspension system is an important part of the vehicle and has a great influence on the driving smoothness and handling stability of the vehicle. As the guiding and force transmission element of the vehicle suspension system, the control arm transmits various forces acting on the wheel to the body, while ensuring that the wheel moves along a certain trajectory, and its layout and structural dimensions directly determine the motion characteristics and ride comfort of the suspension system. The front mounting bracket of the lower control arm of the front suspension of the car is a frequently used device in the automotive industry. The requirements for the front mounting bracket of the lower control arm of the front suspension of the car are very high in terms of auto parts. The front mounting bracket reinforcement plate of the lower control arm of the front suspension of the car is an auxiliary component of the front mounting bracket of the lower control arm of the front suspension of the car, which plays an important role in the operation and work of the car and has an important role.

[0003] As the automobile industry becomes more and more sophisticated, the requirements for automobile accessories are also getting higher and higher. This requirement is not only reflected in the quality of the accessories, but also in the control of the accessory manufacturing process. In the prior art, stamping dies are usually used to process and produce automobile front suspension lower control arm front mounting bracket reinforcement plates (referred to as automobile front suspension bracket reinforcement plates). Generally, stamping dies include upper dies and lower dies. When in use, the material is placed on the lower die, and the upper die is controlled to stamp downward to separate or plastically deform the material, thereby obtaining the required parts. The automobile front suspension bracket reinforcement plate is a special-shaped part composed of multiple curved surfaces, such as Figure 1 As shown in the figure, its structure is relatively complex, and multiple stamping dies are required for multiple stamping processes, including primary forming, secondary forming, side trimming, side repair, and secondary side trimming.

[0004] The existing secondary molding die for the reinforcement plate of the front suspension bracket of an automobile can usually only punch out a part of the structure. If the wing plates on both sides of the web and the tail plate at the rear of the web need to be initially punched out, multiple dies or multiple stamping processes are required, which is relatively complicated and affects the processing accuracy.
