Description

Technical Field

[0001] The utility model relates to the technical field of profile sawing tools, in particular to a flexible self-cleaning sawing tool. Background Art

[0002] Currently, cold cutting with a metal circular saw (or band saw) is the most common method for cutting pipes and profiles. The jig cavity used for sawing is typically contoured to the workpiece being cut, with jigs of varying sizes corresponding to different sizes of pipe. This design necessitates replacing the jig with a corresponding size each time a workpiece size changes, which is not only time-consuming and labor-intensive, but also extremely costly. Furthermore, during the sawing process, traditional jigs also suffer from the problem of residual iron filings adhering to the jig cavity, which is difficult to clean. This can cause pitting and other unsightly effects on the workpiece clamping area. Currently, manual cleaning is often used, which is time-consuming and labor-intensive. Consequently, a sawing jig with a multi-size application and a cavity that is easy to clean is urgently needed. Utility Model Content
