Technical Field
[0001] The utility model relates to the technical field of aviation plate cutting tools, in particular to a strip cutter for soft and thin aviation plate. Background Art
[0002] For hard plates with a thickness of more than 1mm, shearing machines are currently used in workshops for cutting and trimming. However, in the aviation field, small soft plates with a thickness of less than 1mm are often encountered, such as the embedded copper strips in the rubber jackets on aircraft used to release static electricity on metal parts. For such soft and thin plates, the thickness is thin, the material is soft, and the cutting size is small. Generally, they are required to be cut into slender and narrow strips, and shearing machines are not applicable.
[0003] For this type of soft and thin aviation sheet, the current method of cutting is mainly manual marking and then cutting with scissors. However, this method is time-consuming and the cutting efficiency is not high. In addition, because the sheet is soft and thin, the scissors are prone to getting stuck when cutting, and the cutting quality is not high. Therefore, it is urgent to design a soft and thin aviation sheet cutter to improve the above problems and meet the production and use requirements. Summary of the invention
