With the increasing global attention to environmental protection and sustainable development, the new energy vehicle market has risen rapidly. As the core component of new energy vehicles, the manufacturing quality of components has a decisive impact on the performance, safety and life of the vehicle. As an important forming technology, hot die forging plays an important role in the manufacturing of new energy automobile parts, but also faces a series of challenges. This paper will discuss the application of hot die forging process in the manufacturing of new energy automobile parts and the challenges it faces.
Application of hot die forging process in new energy automobile parts manufacturing
Lightweight parts manufacturing: New energy vehicles have extremely high requirements for lightweight in order to improve energy efficiency and driving performance. The hot die forging process can produce parts with complex shapes, high strength and light quality, such as aluminum alloy body components, titanium alloy engine parts, etc., to meet the lightweight needs of new energy vehicles.
High-strength connectors: Hot die forging process can produce connectors with excellent mechanical properties, such as high-strength bolts, connecting rods, etc. These connectors are critical to the structural stiffness and safety of new energy vehicles.
Large-scale production capacity: The hot die forging process has the characteristics of high efficiency and high precision, which is suitable for large-scale production. The rapid growth of the new energy vehicle market requires component manufacturers to have efficient production capacity, and the hot die forging process can meet this demand.
The challenge of hot die forging process in new energy auto parts manufacturing
Material selection and treatment: New energy vehicle parts need to have lightweight, high strength and corrosion resistance. Therefore, when selecting a suitable lightweight alloy material, it is necessary to take into account its formability, mechanical properties and corrosion resistance. At the same time, processing these materials to obtain excellent hot-die forging properties is also an important challenge.
High precision forming requirements: The precision requirements of new energy automobile parts are extremely high, especially those parts involving key connections and transmission parts. Hot die forging process needs to precisely control the flow behavior of the metal, ensure that the forming accuracy meets the design requirements, and prevent the performance reduction or safety risks caused by errors.
Production cost control: Although the hot die forging process has the advantages of high productivity, in the manufacturing of new energy automobile parts, it is still necessary to control production costs to meet the requirements of market competition. This involves process optimization, mold design and manufacturing, energy management and many other aspects.
Environmental protection and sustainable development: hot die forging process involves heating, cooling and other processes, and has certain energy consumption and emissions. In the manufacturing of new energy auto parts, environmental protection measures need to be taken to reduce energy consumption and reduce emissions, in line with the requirements of sustainable development.
The hot die forging process has a wide application prospect in the manufacturing of new energy automobile parts, which can meet the key needs such as lightweight and high strength, and has the potential for large-scale production. However, it also faces the challenges of material selection, high-precision forming requirements, production cost control and environmental protection and sustainable development. Through further research and technological innovation, these challenges can be overcome and the continuous development and application of hot die forging process in the manufacturing of new energy automobile parts can be promoted.
