Ultra-thin metal sheet processing production line and processing method

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the Patent Office of China on January 12, 2024, with application number 202420093089.X and application name “A kind of ultra-thin metal sheet processing production line”, and the Chinese patent application filed with the Patent Office of China on June 10, 2023, with application number 202310683981.3 and application name “A kind of ultra-thin metal sheet processing production line and processing method”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of ultra-thin metal sheets, and in particular to an ultra-thin metal sheet processing production line and a processing method. Background Art

[0004] Traditional steel-related processes often use "thick, tough, and heavy industry" as quality standards, but in order to be suitable for high-tech industries, the field of ultra-thin metal sheet technology has become a battleground for related companies.

[0005] The concept of ultra-thin metal sheet is rooted in ultra-thin precision strip steel. Different from the thickness of conventional stainless steel sheets, stainless steel strip steel with a thickness of ≤0.3mm and as thin as 0.01mm is generally called ultra-thin precision strip steel. It belongs to the field of stainless steel specialization, and the definition of "ultra-thin" thickness of ultra-thin metal sheet is similar to this.

[0006] Reprocessing the surface of ultra-thin metal sheets is a very difficult technology in itself. This is because there are the following technical obstacles when processing ultra-thin metal sheets:

[0007] Traditional methods, such as screw tightening and pressure fixation with a pressure plate, cannot be used. When processing (milling or grinding) metal sheets, vibration will inevitably occur. Due to the ultra-thin nature of ultra-thin metal sheets, the vibration will directly lead to processing failure.

[0008] Because ultra-thin metal sheets are so thin, processing them into irregularly shaped sheets with uneven thickness and using them to make pipes is extremely difficult. For example, the traditional metal pipe-making process involves cutting stainless steel sheets into the required width, then rolling and welding them through pipe-making equipment. The metal pipes produced using this traditional process are relatively thick, with the thinnest diameter being around 2.00mm-4.00mm. Therefore, if you want a metal pipe with a finer diameter, you must stretch it multiple times. During the stretching process, the diameter of the metal pipe becomes thinner and the wall thickness of the metal pipe becomes thinner. However, the difficulty of each stretching is related to the ratio of the metal pipe wall thickness before and after the stretching. After several stretchings, the difficulty of stretching the metal pipe increases exponentially, and the metal pipe is prone to breakage during stretching, making it impossible to produce an ultra-thin and strong metal pipe.

[0009] The Chinese patent with publication number CN219052473U is a production line for ultra-fine seamless metal tubes applied by the applicant on October 13, 2022, including: a material rack, a feeding mechanism, a positioning mechanism, a pre-pressing mechanism, a second positioning mechanism, a forming mechanism, a third positioning mechanism, and a welding mechanism. The seamless metal tube is produced using rolled metal sheets as production raw materials. The ultra-thin metal sheet has an irregular shape, the thinnest end of the metal sheet is not less than 0.02mm and not more than 0.3mm, and the thickest end of the metal sheet is not less than 0.05mm and not more than 0.5mm, preferably 0.02mm-0.2mm. The thickest end and the thinnest end have a uniform thickness transition range. The precision requirements for the processing equipment are high, and it has not yet been domestically produced. Although foreign countries have been able to produce such irregularly shaped metal sheets, their production process is not public, and it is difficult to discharge processing debris during processing, which can easily cause damage to mechanical equipment.

[0010] Therefore, the ultra-thin metal sheet processing production line in the prior art needs to be improved.
