Abstract

The invention discloses biaxial orientation processing equipment for a thermoplastic plastic pipe. The equipment comprises an extruder, a cooling device, a front traction device, a heating device and a back traction device in turn according to a process flow, wherein an extension core mold is arranged in the heating device; and the heating device consists of a water groove which is partitioned into a preheating region, a heating region and a cooling region. The processing equipment takes the water groove as the heating device, has the characteristics of simple structure, easiness of manufacturing and low manufacturing cost, heats the pipe by water temperature, has the advantages of easiness of temperature control, stable temperature and uniform pipe heating and contributes to enhancing the quality of the pipe.

Description

technical field [0001] The invention belongs to the technical field of processing thermoplastic pipes, and in particular relates to a biaxial orientation processing equipment for thermoplastic pipes. Background technique [0002] Through biaxial orientation, the thermoplastic pipe can greatly enhance the strength and impact resistance of the pipe, so that the wall thickness of the pipe can be greatly reduced without reducing the hydraulic blast resistance strength of the pipe, so as to reduce the cost of pipe products and save raw materials. . [0003] In the prior art, the biaxial orientation processing device for thermoplastic pipes is relatively complicated, and the equipment cost is high. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a thermoplastic pipe biaxial orientation processing equipment with simple processing technology, simple equipment structure and low equipment cost, so as to overcome the short...
