1. The fully enclosed round pipe polishing machine adopts a production line with weldable continuous longitudinal section shape and an integrated production line without welding joints, with a relatively simple process. All are continuous longitudinal section shapes. The thickness is about 5-8mm, and the number of inner and outer circular cross sections is about 12, which is basically the same as that of the traditional round pipe polishing machine. When undertaking the outer circular elbow with two corners on three shafts, it is mainly for forming and working procedures.


Therefore, the renovation of three pipe jacking grooves and the production of two bearing sealing grooves have been completed with high efficiency and dual function groove pipe, and the interface is relatively simple.


2. The fully enclosed round tube polishing machine requires more production machinery than the traditional round tube polishing machine. The automatic management of multiple machines in the production line has been realized, and the semi epoxy resin, seam filling and molten resin products from the mold have been completed respectively. Advantages: it is mainly different from the traditional round pipe method. After heat treatment, it can better realize automatic management both internally and externally.
