Description

Technical Field

[0001] The invention relates to the technical field of processing and production, in particular to an ultra-thin metal sheet processing production line and a processing method. Background Art

[0002] 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 is a battleground for related companies.

[0003] 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.

[0004] 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:

[0005] Traditional methods, such as screw locking and pressure fixation with a pressure plate, cannot be used. When metal sheets are processed (milling or grinding), vibrations will definitely occur. Due to the ultra-thin characteristics of ultra-thin metal sheets, the vibrations will directly lead to processing failures.

[0006] Because the thickness of ultra-thin metal sheets is very thin, it is very difficult to process them into special-shaped sheets with uneven thickness and to make pipes with them. For example, the traditional metal pipe making process is to cut the stainless steel sheets into the required width, and then roll and weld them through the pipe making equipment. The metal pipes obtained by this traditional process are relatively thick, with the thinnest diameter being around 2.00mm-4.00mm. On this basis, if you want to get a metal pipe with a thinner diameter, you must stretch the metal pipe several times. During the stretching process, the diameter of the metal pipe will become thinner and the wall thickness of the metal pipe will become thinner. However, the difficulty of each stretching is related to the ratio of the wall thickness of the metal pipe after the stretching to the wall thickness of the metal pipe before the stretching. After several stretchings, the stretching difficulty of the metal pipe becomes greater, which is similar to exponential growth, and the metal pipe is easy to break during stretching, and it is impossible to make an ultra-thin and strong metal pipe.

[0007] The Chinese patent with publication number CN219052473U is a production line for ultra-fine seamless metal tubes applied by the inventor 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 to obtain seamless metal tubes. The rolled metal sheets are used as production raw materials. The ultra-thin metal sheets are irregular in shape, and the thinnest end of the metal sheet is not less than 0.02mm and not more than 0.3mm. 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 of the processing equipment are high, and it has not yet been domestically produced. Although foreign countries have been able to produce 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.
