As the most common mode of transportation in the 21st century, the car is greatly changing people's travel, and the concept of car cover is also more into the hearts of the public.
Automotive panels are sheet metal sheets composed of metal and composite materials that cover the surface of the engine, chassis, cab and body. According to the function and position, it can be divided into three categories: external covering, internal covering, and skeleton covering.
Automobile panels have different characteristics from general stamping parts in terms of process design, mold processing, equipment selection and quality control.
Metal: Metal is one of the main materials for automotive panels, and common metal materials include steel plate and aluminum plate. Steel sheets are usually made through a cold stamping process, while aluminum sheets are made through a cold rolling process. The metal cover has enough strength and stiffness to protect the paint finish on the hood surface and prevent ageing.
Composites: In higher-end cars, especially high-performance sports cars, the commonly used hood material is composites, such as carbon fiber. Composites are lightweight, high strength and heat resistant, making them suitable for covering high-performance sports cars.
In addition to the above-mentioned materials, automotive covering materials also include sound-absorbing cotton, engineering plastics, etc.
In CNC machining, the stamping process is the most important link in the processing process of the entire automobile panel, and its quality directly affects the quality and service life of the product. The basic processes of stamping and forming of automobile panels include blanking, pre-bending, drawing, trimming, punching, flanging, shaping and other processes. In this process, it is necessary to pay attention to the selection of punches, the design and optimization of shearing dies and forming molds, etc., to ensure production efficiency and processing quality.
Die is one of the keys to stamping processing, and its design and manufacturing have a great impact on machining accuracy and cost. In the stamping process of cover parts, special attention should be paid to the design and manufacture of molds to ensure that they are suitable for materials and reasonable with process production requirements, so as to improve the yield and reduce manufacturing costs.
Fourth, surface treatment.
After the stamping of the cover is completed, surface treatment is also required, that is, leveling, polishing, spraying and other links. Surface treatment can not only enhance the decorative performance of the product beautifully, but also improve the wear resistance, corrosion resistance and corrosion resistance of the product, and ensure the stability and long-term service life of the product.
To sum up, the stamping process of the cover is a relatively complex process, involving materials, stamping process, mold design and surface treatment. In order to obtain high-quality automotive panels in this process, it is necessary to carry out detailed planning and implementation of each link to improve processing efficiency and product quality, while also laying a solid foundation to better meet market demand.
