Description

Technical Field

[0001] The utility model relates to a stamping and shaping die, in particular to a stamping and shaping die for the left half of a lower thrust rod bracket plate, and belongs to the field of automobile accessory die design. 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 getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. Thrust rods are commonly used in the automotive industry, and the requirements for thrust rods in auto parts are very high. The thrust rod bracket plate is an auxiliary component of the thrust rod, which plays an important role in the operation and work of the car. The left / right bracket plate of the lower thrust rod of the car is one of the indispensable parts of the car.

[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 the left / right bracket plates (inner or outer plates of the bracket) of the automobile lower thrust rod. Generally, the stamping die includes an upper die and a lower die. 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 lower thrust rod bracket plate is a special-shaped part composed of multiple curved surfaces (and includes left and right parts), which includes a central plate body and a bent wall on the plate body. The central plate body is provided with a matching hole groove, such as Figure 1 The structure of the lower thrust rod bracket plate is relatively complex, and multiple stamping dies are required for multiple stamping processes, including primary forming (stamping the central plate), secondary forming (bending the wall, etc.), separation (separation of the left and right parts and punching, etc.) and shaping, among which stamping and shaping play an important role in the entire product production process.

[0004] During the production process of the lower thrust rod bracket plate, the raw material plate is prone to plane bending or edge warping after a series of processing operations such as folding, punching and separation, which affects the product quality and is not convenient for later assembly and use. In order to ensure the quality of the product, a stamping shaping mold is usually used for shaping. The existing stamping shaping molds for the lower thrust rod bracket plate have complex structures and high costs. When used, the yield rate is low and the part quality is not high. Some of them also require multiple shaping, which leads to cumbersome shaping steps, an increase in mold parts, and further increases in mold costs.
