The invention belongs to the technical field of HDPE (high-density polyethylene) pipeline manufacturing equipment, and particularly relates to a self-centering clamping device for HDPE pipeline manufacturing. The self-centering clamping device for HDPE pipeline manufacturing comprises a supporting seat and an outer gear ring, wherein supporting rollers and a driving gear are arranged in the supporting seat, the outer gear ring is embedded into the upper end of the supporting seat, the outer diameter side of the outer gear ring abuts against the supporting rollers, an outer gear is arranged on the outer diameter side of the outer gear ring, the diameter of the addendum circle of the outer gear is smaller than the diameter of the outer edge of the outer gear ring, the driving gear is driven by a driving piece arranged in the supporting seat and meshed with the outer gear arranged on the outer gear ring, a plurality of telescopic assemblies are embedded in the inner diameter side of the outer gear ring, the side, away from the outer gear ring, of each telescopic assembly is connected with a curvature adjusting wheel, and each curvature adjusting wheel is used for adapting to pipes with different diameters by adjusting the curvature radius of the generatrix of the curvature adjusting wheel. The self-centering clamping device for HDPE pipeline manufacturing is simple in structure and reasonable in design, axial movement and axial rotation of the pipeline can be achieved, machining convenience is greatly improved, centering can be rapidly conducted, and the axis of the pipeline is kept unchanged all the time.
Description
technical field [0001] The invention belongs to the technical field of HDPE pipe preparation equipment, in particular to a self-centering clamping device for HDPE pipe preparation. Background technique [0002] With the rapid progress of polymer material science and technology, the deepening of the development and utilization of plastic pipes, and the continuous improvement of production technology, plastic pipes have fully demonstrated their excellent performance. Today, plastic pipes are no longer mistaken for "cheap substitutes" for metal pipes. In this revolution, polyethylene pipes are favored and are increasingly shining brightly. They are widely used in gas transmission, water supply, sewage discharge, agricultural irrigation, fine particle solid transportation in mines, as well as oil fields, chemicals, post and telecommunications, etc., especially in fields such as It has been widely used in gas transportation. [0003] HDPE is a thermoplastic polyolefin produced ...
