Abstract

The invention discloses a forming process for an automobile high-strength plate chassis part. The forming process comprises the following steps of: S1, manufacturing a hub mould: designing the hub mould according to a three-dimensional model, processing blank to form the hub mould, uniformly coating zinc stearate powder on the surface of the hub mould, and sintering the hub mould; S2, weighing rubraw materials in parts by weight; S3, mixing the hub raw materials; S4, forming a hub; and S5, performing surface treatment on the hub: soaking and passivating the hub with zinc plating liquid, vacuum-drying the electrostatic-sprayed hub and performing baking varnish processing. The forming process can improve operation efficiency of hub forming processing, shortens rub forming time, reduces hubprocessing production cost, and meets batch production requirements of the hub; and mixed processing is selected for the hub materials, so that hardness, rigidity, impact resistance and tensile strength of the formed hub are improved, the using performance of the hub is improved, and the usage period of the hub is prolonged.

Description

technical field [0001] The invention relates to the technical field of molding and processing of auto parts, in particular to a molding process for chassis parts of high-strength boards of automobiles. Background technique [0002] With the widespread application of high-strength plates in automotive chassis components, product design has become more complex, making product processing more difficult. High strength is a material with high yield strength, low elongation, and poor plasticity. With the increase of sheet strength, the traditional cold stamping process is prone to cracking during the forming process, which cannot meet the processing requirements of high-strength steel plates. The wheel hub is a part of the chassis components. The wheel hub is a barrel-shaped metal part with the center mounted on the shaft that supports the tire inner profile. It is also called a wheel rim, a steel ring, a wheel, and a tire bell. There are many different methods and materials. In...
