Description

Technical Field

[0001] The invention relates to the technical field of machining, in particular to a clamping unit and a clamping device for machining ultra-thin metal sheets. Background Art

[0002] 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.

[0003] 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:

[0004] 1. Traditional methods such as screw tightening and pressure plate fixing cannot be used

[0005] As disclosed in the Chinese utility model patent with publication number CN219542413U, a steel cutting fixture comprises a base, two positioning assemblies are arranged on the base at intervals, the positioning assembly comprises a base body and a cover body rotatably connected to the base body, the base body is provided with a first limit block, and a first profiling groove is arranged on a side of the first limit block close to the cover body, the cover body is provided with a movable second limit block and a first elastic member driving the second limit block close to the first limit block, the second limit block is provided with a second profiling groove connected to the first profiling groove, the cover body is also provided with a rotatable locking rod, and a limit rod perpendicular to the locking rod is arranged at one end of the locking rod close to the base body, the base body is provided with a locking plate and a locking hole penetrating the locking plate, the locking hole is for one end of the locking rod with the limit rod to pass through the locking plate, the locking rod is also sleeved with a second elastic member, and after the limit rod passes through the locking hole, the second elastic member drives the limit rod to move in a direction close to the locking plate and abut against the locking plate. The locking rod locking and the limit block pressing and 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.

[0006] 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.

[0007] The existing technologies focusing on this change in processing state include Chinese utility model patent with application number 202122375112.3, Chinese utility model patent with application number 201920389406.1 and Chinese utility model patent with application number 202222534355.1, but 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.

[0078] The pressing member in this embodiment is the front roller 452, and the abutting member is the rear roller 442, so that the ultra-thin metal sheet is not easily scratched, but the blade of the tool is at a certain distance from the contact area where the roller presses the ultra-thin metal sheet, which is not conducive to controlling the vibration of the sheet when processing the ultra-thin metal sheet.

[0079] Embodiment 6

[0080] This embodiment provides a clamping device for processing ultra-thin metal sheets, such as Fig.10 As shown, the ultra-thin metal sheet processing clamping device of this embodiment is provided with a first clamping unit on the left side and a second clamping unit on the right side.

[0081] In this embodiment, the first clamping unit includes an adjusting device, a pressing member and a supporting member. The pressing member presses the ultra-thin metal sheet against the supporting member through the adjusting device. The adjusting device includes an elastic device that provides adaptive elastic deformation force for processing the ultra-thin metal sheet.

[0085] The pressure plate includes a first pressure plate 451, which has through holes on the upper and lower parts respectively. The bottom plate 441 is fixedly connected to the connecting column 661, and the through holes correspond to the connecting column 661. The first pressure plate 451 is movably connected to the bottom plate 441 through the through holes. There is a flat surface between the through holes of the first pressure plate 451. A channel 41 is arranged between the first pressure plate 451 and the bottom plate 441, and the channel 41 is used to place ultra-thin metal sheets.

[0086] The structural difference between the second clamping unit of the present embodiment and the first clamping unit of the present embodiment is that the clamping member is a pressure plate combination, and the pressure plate combination includes a second pressure plate 453 and a third pressure plate 454, which are arranged in sequence, and a spring 64 is arranged between the second pressure plate 453 and the third pressure plate 454, and 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, and the bottom plate 441 is fixedly connected to the connecting column 661, and the through hole corresponds to the connecting column 661, and the second pressure plate 453 and the third pressure plate 454 are both movably connected to the bottom plate 441 through the through hole, and a channel 41 is arranged between the first pressure plate 451 and the bottom plate 441, and the channel 41 is used to place an ultra-thin metal sheet, and a groove is formed between the through holes of the third pressure plate 454, such as Fig.11a shown.

A processing window 421 is provided near the ultra-thin metal sheet to be processed in the tool groove 42. The tool groove 42 is communicated with the groove. The tool groove 42 is specifically a U-shaped groove. The U-shaped groove is a preferred implementation method of the tool groove 42, which can be composed of two parts as shown in FIG. Fig.11c The inclined arc surfaces of the pressing plate shown are spliced ​​together, or can be formed in one piece without splicing.

[0088] Effect:

[0089] 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 hand wheel 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 extends 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 pressed as tightly as possible over the largest area when being processed, thereby 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.

[0090] The ultra-thin metal sheet to be processed passes through the first clamping unit to the area where the tool is located. After the processing operation, 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 can prevent the wear of the processed ultra-thin metal sheet and protect the processed ultra-thin metal sheet. As mentioned above, the processing of ultra-thin metal sheets is a process that requires feeding and unloading. The setting of the elastic device solves the problem of sheet pressing and transmission transportation, so that the sheet can be fixed and in a state that can be processed, and gives the sheet a certain adaptive elastic deformation force, so that the sheet can be transported in and out.

[0091] This embodiment effectively positions the ultra-thin metal sheet and has a stronger effect of 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.

[0092] In some other embodiments, the structural difference between the second clamping unit and the first clamping unit lies in that the clamping member is a pressure plate combination, which 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, 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 are all slidably matched with the threaded adjustment column, a spring is arranged between the fifth pressure plate and the fourth pressure plate, a spring is arranged between the sixth pressure plate and the fourth pressure plate, the fourth pressure plate has through holes at the top and bottom, the fifth pressure plate has a through hole corresponding to the through hole above the fourth pressure plate, 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, 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, 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 arranged between the fifth pressure plate and the sixth pressure plate. A tool groove is formed between the first pressing plate, the fifth pressing plate and the sixth pressing plate. A processing window is provided near the ultra-thin metal sheet to be processed in the tool groove, and the tool groove is connected to the gap. That is, to a certain extent, the third pressing plate is split into two upper and lower pressing plates, which can better facilitate chip removal and reduce the situation of chip blockage, which is more conducive to the discharge and cleaning of the chips generated during processing, and is more conducive to the industrialization of ultra-thin metal sheet processing.
