Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to an ultra-thin metal sheet clamping processing mechanism. 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] For example, the Chinese utility model patent with publication number CN219542413U discloses a steel cutting fixture, comprising 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 contoured 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 contoured groove connected to the first contoured 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.

[0103] Effect:

[0104] 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 inclined arc surface 42, 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 inclined arc surface 42 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 right side of the tool 31 is empty and there is no device set, which is conducive to chip removal and the operation of the industrial production line.

The tool is driven by the tool driving mechanism to approach the ultra-thin metal sheet processing area and process the 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 compression 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.
