Automobile lightweight refers to the use of new materials, new designs and new processes to reduce the weight of the whole vehicle, thereby improving the power and fuel economy of the car and reducing emission pollution. Electric vehicles place new demands on lightweight. New energy vehicles have high requirements for lightweight, and the cruising range can be increased by 10% per 100kg of weight reduction, and it is expected that the use of aluminum alloy bicycles in new energy vehicles will increase to 250kg by 2020. The body and chassis are the two parts with the greatest weight reduction, which can reduce weight by more than 190kg and 160kg respectively.
Automotive lightweight technology has become one of the important directions for the development of China's new energy vehicle industry, which is also the basic technology for the development of new energy vehicles. Experiments have shown that if the weight of the vehicle is reduced by 10%, the energy efficiency can be increased by 6%-8%, and the cruising range can be increased by 5.5%.
When it comes to automobile lightweight, we have to mention the three-dimensional five-axis laser cutting machine, with the gradual rise of electric vehicles, laser technology plays an increasingly important role in the automobile manufacturing process. In particular, the three-dimensional five-axis laser cutting machine that has gradually emerged in recent years has become an important processing tool in the automotive processing industry.
Senfeng Laser's three-dimensional five-axis laser cutting machine can effectively solve the "pain points" of three-dimensional curved surfaces, special-shaped surfaces and other workpiece molding, like a pearl, which plays a key role in helping automobiles lightweight.
Senfeng three-dimensional five-axis laser cutting machine conducts high-density, high-energy beam through optical fiber, adopts non-contact three-dimensional flexible and rapid processing of parts, trimming, hole cutting, replacing trimming die and punching die, helping to shorten the production cycle of new models and reduce manufacturing costs. Its flexibility, speed and high stability solve the problems of many molds and high loss rate in the traditional stamping method, and truly realize the flexible processing of intelligence, multi-function, high efficiency and low energy consumption.
(1) High-strength steel three-dimensional parts with high precision, high quality and high efficiency.
(2) No secondary processing is required, and the comprehensive efficiency is 3-5 times higher.
(3) Not limited by mold, arbitrary cutting scalability.
(4) There is no need to replace the mold, and the cost of use is reduced by more than 1 times.
(5) Complete multiple processes such as cutting, trimming die, punching die, six-axis robot three-dimensional cutting machine and wire cutting at one time.
The new energy automobile industry is the transformation of the mainland from a major automobile country to an automobile power, a strategic measure to address climate change and promote green development, and has also become one of the important forces in the development and transformation of the world's automobile industry. According to the "New Energy Vehicle Industry Development Plan (2021-2035)", new energy vehicles will bring greater changes, and Senfeng three-dimensional five-axis laser cutting machine will continue to improve and innovate under this wave, bursting with greater energy and light for the automotive industry!
