Description

technical field [0001] The invention relates to a post-processing machine for plastic pipes, in particular to a vertical high-precision post-processing machine for plastic pipes. Background technique [0002] After some large plastic pipes are injection molded and cooled, the surface will partially shrink, resulting in uneven surface roundness, or some plastic pipes have a slightly larger outer diameter after injection molding, which cannot meet the use requirements. Secondary processing of the tubing is required to achieve uniform roundness on the outer surface or to a specified outer diameter. The existing technology is to put the injection-molded plastic pipe on the machine tool for secondary processing, and the processing efficiency is low, which affects the production efficiency, and the processing of large-diameter pipes requires a large machine tool, which is large in size, takes up a lot of space, and the manufacturing cost high.

[0002] After some large plastic pipes are injection molded and cooled, the surface will partially shrink, resulting in uneven surface roundness, or some plastic pipes have a slightly larger outer diameter after injection molding, which cannot meet the use requirements. Requires secondary processing of the tubing to achieve uniform roundness on the outer surface or an outer diameter of the specified size

The existing technology is to put the injection-molded plastic pipe on the machine tool for secondary processing, and the processing efficiency is low, which affects the production efficiency, and the processing of large-diameter pipes requires a large machine tool, which is large in size, takes up a lot of space, and the manufacturing cost high
