Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] see Figure 2-9 As shown, a processing mold of a lined X-shaped cross HDPE winding pipe includes a mold body 200 connected to a supply of molten HDPE raw material equipment, and the molten HDPE raw material is supplied from one end of the mold body 200, and from the mold body 200 The other end of the tube is extruded to form an X-shaped square tube 100 with an X-shaped cross structure inside. The mold body 200 includes a rectangular outer core 201 penetratin...

Abstract

The invention discloses a machining mold for a lining X-shaped crossed HDPE winding pipe, belongs to the technical field of pipeline machining, and discloses an X-shaped square pipe with an X-shaped crossed structure inside, which is formed by supplying a molten HDPE raw material from one end of a mold body and extruding the molten HDPE raw material from the other end of the mold body. Right-angle triangular prism-shaped inner cores are arranged in the outer core, one ends of the inner cores are connected and supported with the end cover, the four inner cores are symmetrically arranged up and down and left and right, the inclined planes of the inner cores are parallel to the inner wall planes of the corresponding outer core, and first channels are reserved between the inclined planes of the inner cores and the inner wall planes of the corresponding outer core; the right-angle planes of the adjacent inner cores are parallel to each other, a second channel is reserved between the right-angle planes of the adjacent inner cores, the first channel and the second channel jointly form a cavity, and the winding pipe manufactured by winding the square pipe with the X-shaped structure inside is high in compression resistance and has deformation prevention and fracture prevention performance.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a processing die for an inner-lined X-shaped cross HDPE winding pipe. Background technique [0002] Winding pipes account for about 20% of municipal drainage pipes. The production process of winding pipes is simple, which can realize the production of large-diameter (3000mm) drainage pipes. At the same time, winding pipes are environmentally friendly, economical and durable, and are suitable for large-scale promotion in municipal drainage pipes. , has broad market prospects and economic value. The existing winding pipe production process is as follows: high-density polyethylene (HDPE) is used as the main raw material for the pipe produced, and the extruder first extrudes the molten raw material in the form of a hollow square tube, then cools the hollow square tube, and finally Enter the winding forming machine to glue the hollow square tubes in the form of spiral wires. ...
