Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a universal cutting tool for PVC pipe fittings. Background Art

[0002] PVC pipe (PVC-U pipe) is a rigid polyvinyl chloride pipe, which is made of polyvinyl chloride resin, stabilizer, lubricant, etc. and then extruded by hot pressing. It is the earliest plastic pipe to be developed and applied. PVC-U pipe has strong corrosion resistance, easy bonding, low price and hard texture. However, due to the leakage of PVC-U monomer and additives, it is only suitable for water supply systems with a conveying temperature not exceeding 45°C. Plastic pipes are used for drainage, wastewater, chemicals, heating and cooling liquids, food, ultra-pure liquids, mud, gas, compressed air and vacuum system applications.

[0003] During the long-term cutting of PVC pipe fittings, the surface of the cutting tool will be contaminated with and accumulate more and more debris and impurities. These debris and impurities cannot be effectively cleaned for a long time, which will affect the subsequent cutting work and reduce the quality of the cut PVC pipe fittings. However, when the cutting tool is cleaned, the cutting work cannot be carried out. Cutting can only be continued after the cleaning is completed, resulting in reduced work efficiency. Therefore, the present application proposes a universal cutting tool for PVC pipe fittings. Summary of the invention
