Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to a cutting auxiliary clamp. Background Art
[0002] Metal sheets can be used to manufacture various products and parts for industries such as construction, automobiles, electronics, and aerospace. Ultra-thin metal sheets refer to sheets with a thickness of no more than 0.2 mm, which are often used in the electronics industry. Ultra-thin metal sheets can also be used to manufacture high-precision connectors through precision machining in the electronics industry to ensure reliable connection of electronic equipment. When processing ultra-thin metal sheets, an auxiliary clamping device for ultra-thin metal sheet wire cutting is required to fix the sheet to prevent the sheet from moving and affecting the processing accuracy.
[0003] Traditional processing methods are limited to cutting ultra-thin metal sheet parts with metal tools. Since the material itself is too thin, ultra-thin metal sheet parts are very easy to deform during the mechanical cutting process, making the traditional mechanical processing process very difficult, thus affecting the size and precision of the ultra-thin metal sheet. This processing method makes the parts very rough and difficult to form in one go. They are often scrapped due to the inability of mechanical processing to meet the process size requirements, resulting in waste.
