Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy processing, and in particular to a bicycle aluminum alloy stretching forming method and system. Background Art

[0002] Aluminum alloy processing is an important branch in the field of metal processing, mainly involving various forms of processing using the excellent properties of aluminum alloys such as low density, high strength, excellent conductivity and corrosion resistance, including casting, welding, machining and forming of aluminum alloys, especially forming technologies such as stretch forming, extrusion and stamping. In modern industrial production, the development of aluminum alloy processing technology is constantly optimized to meet the needs of industries such as aerospace, transportation, construction and packaging, and promotes the design concept of lightweight, structural optimization and functional integration.

[0003] Among them, the bicycle aluminum alloy stretching forming method is to stretch and form the aluminum alloy material into specific bicycle parts through mechanical force. The main purpose is to produce lightweight, high-strength bicycle parts, such as frames, handlebars, etc. The use of stretching forming technology can ensure that the parts have good mechanical properties and durability, while also optimizing the overall structural design of the bicycle. It is a common method used in the bicycle manufacturing industry to maximize the use of materials and optimize product performance.

[0004] Existing aluminum alloy processing technologies generally lack the ability to monitor and dynamically adjust the temperature and stress distribution during the forming process in real time. This static processing method may lead to uneven mechanical properties of the finished product. For example, some areas may be insufficient or too hard due to inaccurate temperature control, affecting the overall performance and life. In addition, if the stretching speed is not adjusted in real time, the best forming effect is often not achieved for aluminum alloy parts of different thicknesses, which is particularly unfavorable in fields such as aerospace with high precision requirements. The lack of fine temperature control and stretching speed optimization will also increase material waste and production costs, because unqualified parts need to be reprocessed or scrapped, which has an adverse impact on the production efficiency and product competitiveness of enterprises in the highly competitive industrial market.
