Description

Ultra-thin metal sheet processing clamping unit, clamping device and processing equipment

[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 9, 2024, with application number 202410036844.5 and application name “A ultra-thin metal sheet processing clamping unit and clamping device”, and the Chinese patent application filed with the Patent Office of China on June 9, 2023, with application number 202310683094.6 and application name “A ultra-thin metal sheet processing equipment”, 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 clamping unit, a clamping device and processing equipment. Background Art

[0004] 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.

[0005] 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:

[0006] 1. Traditional methods such as screw tightening and pressure plate fixing cannot be used.

[0007] The cam is secured to the base with a first end secured to a first position and a second end secured to a second position relative to the first cam, the cam being secured to the base with a second end secured to a second position relative to the first cam. The locking rod locking and the limit block pressure fixing in this patent are the aforementioned traditional methods. This method can be applied to thicker materials, such as steel or thicker sheets. When processing ultra-thin metal sheets, this traditional clamping method will give the ultra-thin metal sheets excessively strong clamping force, causing deformation of the ultra-thin metal sheets or surface wear.

[0008] 2. When metal sheets are processed (milling or grinding), vibration will definitely occur. Due to the ultra-thin characteristics of ultra-thin metal sheets, the vibration will directly lead to processing failure.

[0009] Existing technologies that focus on this change in processing state include Chinese utility model patent application number 202122375112.3, Chinese utility model patent application number 201920389406.1, and Chinese utility model patent application number 202222534355.1. However, these only address the problem of how to detect, alarm, or record changes when the product to be processed expands during processing, and do not address the problem of vibration of ultra-thin metal sheets.

[0010] In addition, the 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 first positioning mechanism, a pre-pressing mechanism, a second positioning mechanism, a forming mechanism, a third positioning mechanism, a welding mechanism, to produce seamless metal tubes, and use rolled metal sheets as production raw materials. The ultra-thin metal sheet has an irregular 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. The thickest end and the thinnest end have a uniform thickness transition range. Therefore, the precision of the processing equipment is required to be 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.

[0011] Therefore, the ultra-thin metal sheet processing equipment in the prior art needs to be improved.

The second pressure plate 453 has through holes on the top and bottom, and the third pressure plate 454 also has through holes on the top and bottom. The bottom plate 441 is fixedly connected to the connecting column 661, and the through holes correspond to the connecting column 661. The second pressure plate 453 and the third pressure plate 454 are both movably connected to the bottom plate 441 through the through holes. A channel 41 is provided between the first pressure plate 451 and the bottom plate 441. The channel 41 is used to place ultra-thin metal sheets. A groove is formed between the through holes of the third pressure plate 454, as shown in Figure 11a.

[0107] As shown in Figures 11a and 11b, a tool groove 42 is formed between the first pressing plate 451 and the third pressing plate 454. A processing window 421 is provided in the tool groove 42 near the ultra-thin metal sheet to be processed, and the tool groove 42 communicates with the groove. Tool groove 42 is specifically a U-shaped groove. As a preferred implementation of tool groove 42, the U-shaped groove can be formed by splicing the oblique curved surfaces of two pressing plates, as shown in Figure 11c, or it can be formed integrally without splicing.

[0108] Effect:

[0109] The ultra-thin metal sheet is arranged in the channel 41, and the distance between the movable plate 621 and the fixed plate 61 is adjusted by rotating the handwheel 63, thereby adjusting the distance between the movable plate 621 and the pressure plate, so that the pressure plate limits and squeezes the ultra-thin metal sheet to prevent the ultra-thin metal sheet from falling off from the channel 41 and preventing the ultra-thin metal sheet from vibrating; the tool 31 is extended into the U-shaped groove, and the tool 31 partially passes through the processing window 421 and abuts against the ultra-thin metal sheet to process the sheet; the design of the U-shaped groove enables the ultra-thin metal sheet to be compressed over the largest possible area when being processed, avoiding the problem of vibration during the processing of the ultra-thin metal sheet; the groove designed on the third pressure plate 454 is used for chip removal, which is beneficial to the operation of the industrial production line.

[0110] The ultra-thin metal sheet to be processed passes through the first clamping unit to the cutting tool area. After processing, the processed ultra-thin metal sheet is transported out through the second clamping unit. The groove in the middle of the third pressing plate 454 prevents wear on the processed ultra-thin metal sheet, protecting the processed ultra-thin metal sheet. As mentioned above, the processing of ultra-thin metal sheet requires feeding and unloading. The provision of the elastic device solves the problems of sheet compression and transmission and transportation, ensuring that the sheet is fixed and ready for processing, while also providing the sheet with a certain adaptive elastic deformation force, allowing the sheet to be transported in and out.

[0111] This embodiment effectively positions the ultra-thin metal sheet and has a stronger effect in preventing the ultra-thin metal sheet from vibrating during processing. However, compared with the fifth embodiment, the pressing member is more likely to scratch the ultra-thin metal sheet.

[0112] In some other embodiments, the structural difference between the second clamping unit and the first clamping unit is that the clamping member is a pressure plate combination, and the pressure plate combination includes a fourth pressure plate, a fifth pressure plate and a sixth pressure plate. The fourth pressure plate is arranged before the fifth pressure plate and the sixth pressure plate, and the rear side walls of the fourth pressure plate, the fifth pressure plate and the sixth pressure plate are arranged in sequence from top to bottom. The fourth pressure plate, the fifth pressure plate and the sixth pressure plate all slide with the threaded adjustment column, a spring is arranged between the fifth pressure plate and the fourth pressure plate, and a spring is arranged between the sixth pressure plate and the fourth pressure plate. The fourth pressure plate has through holes above and below, the fifth pressure plate has a through hole corresponding to the through hole above the fourth pressure plate, and the sixth pressure plate has a through hole corresponding to the through hole below the fourth pressure plate. The bottom plate is fixedly connected to the connecting column, and the through hole corresponds to the connecting column. The fourth pressure plate and the fifth pressure plate are movably connected to the bottom plate through the through holes in sequence, and the fourth pressure plate and the sixth pressure plate are movably connected to the bottom plate through the through holes in sequence, and a gap is provided between the fifth pressure plate and the sixth pressure plate. A tool groove is formed between the first, fifth, and sixth pressure plates. A processing window is located near the ultra-thin metal sheet to be processed, and the tool groove communicates with the gap. This essentially splits the aforementioned third pressure plate into two, upper and lower plates. This facilitates chip removal and reduces chip blockage, facilitating the removal and removal of debris generated during processing and further facilitating the industrialization of ultra-thin metal sheet processing.
