Abstract

The utility model relates to a pultruded fiber reinforced pipe forming machine, comprising a lengthwise coil holder, a resin pool, an internal core mold, an electric heating external mold and a tube stretcher, which is characterized in that: a winder, which rotates around the internal core mold and winds spiral fiber yarns on the longitudinal fiber yarns, is arranged at the front part of the eclectic heating external mold; two or more bobbins are arranged on the winder. The utility model has the advantages of simple structure, ability to be refitted on basis of prior forming machines, low cost, good efficiency, and capability of producing fiber reinforced profiled pipes resistance to bending, internal pressure and rupture.

Description

Stretching fiber strengthens tube-forming machine

Technical field

The utility model relates to product moulding machinery, particularly is the make-up machine that a kind of producd fibers strengthens the resin section bar.

Background technology

With resin and fiber is raw material, the fiber-reinforced resin tubing that pultrusion on make-up machine, heating, curing form comprises pipe, oblate pipe, rectangular tube, polygon pipe, and the section bar in various cross sections, because having, it is easy to be shaped, have certain intensity, numerous advantages such as corrosion-resistant, easy processing, good insulation preformance, can substituted metal pipe and section bar, range of application is more and more wider.But because the restriction of production process equipment has only glass fiber yarn longitudinally in the existing fiber-reinforced resin tubing.Though hot strength is good, anti-fracture, counter-bending, antiknock is split, press poor-performing in anti-, influence is used.Because existing extruding fiberglass reinforced pipe make-up machine only is made of ordinate frame, resin pool, interior core, electrical heating external mold and tube stretcher, this has just limited the structure and the performance of fiber reinforced pipe.

Summary of the invention

The utility model designs at the defective that has fiber reinforcement tube forming machine now.This make-up machine is made of ordinate frame, resin pool, interior core, electrical heating external mold and tube stretcher, is provided with core rotation in the ring before the electrical heating external mold, twines the wrapping head of yarn on the longitudinal fiber yarn, on the wrapping head two or more bobbins can be arranged.But winding screw shape glass fiber yarn.But the utility model is owing to set up the wrapping head of winding screw shape silvalin, in the section bar of producing, the longitudinal fiber yarn is arranged not only, also have one deck, two-layer, even the multi-layer spiral yarn, thereby the bend resistance of fiber-reinforced resin pipe, the performance that resists interior pressure, antiknock to split have been improved greatly.The utility model is simple and reasonable, can change a social system on the basis of existing make-up machine.Cost is low, profitable.
