Problems solved by technology

During the pre-stacking process, due to the soft nature of the nylon air duct, the composite material layer cannot be effectively supported. When the composite material is pre-stacked, the composite material is easy to squeeze the nylon air duct, causing deformation and making the structure of the composite material layer unstable. , the thickness of the formed pipe fittings cannot be effectively guaranteed, and the defective rate of the product is relatively high

Embodiment Construction

[0027] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0028] Such as figure 1 Shown, a kind of method for manufacturing composite pipe fittings, it comprises the following steps:

[0029] Step 1. Material production: form the polymer composite material into a sheet; heat and pressurize the fast-melting metal to liquefy it, pour it into a metal core mold, and then cool down to solidify it into a metal core whose shape matches the inner cavity of the pipe fitting 1 , and then the metal core 1 is obtained by demoulding;

[0030] Step 2, pre-stacked composite materials: such as figure 2 As shown, several layers of composite materials are stacked on the outer surface of the metal core 1 to form a preformed pipe fitting;

[0031] Step 3, mold entry: place the preformed pipe fitting in the cavity of the pipe fitting mold, and close the mold;

[0032] Step 4, thermos...

Abstract

The invention discloses a method for manufacturing a composite pipe fitting. The method comprises the following steps of material producing, composite pre-stacking, mould entering, thermosetting molding, pipe fitting demolding and inner core taking out. When a composite is pre-stacked, a metal core is utilized to support an air hose and the composite to ensure the structural stability of a composite material layer, so that preformed pipe fitting has a stable shape, thereby improving the excellence rate of pipe fitting production.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a method for manufacturing composite pipe fittings. Background technique [0002] Composite pipe fittings refer to pipe fittings composed of two or more different materials combined in different ways. It can take advantage of the advantages of various materials and overcome the defects of a single material, thereby expanding the application range of materials. Due to the characteristics of light weight, high strength, excellent elasticity, chemical corrosion resistance and good weather resistance, composite pipe fittings have gradually replaced metal alloys and are widely used in aerospace, automotive, electrical and electronic, construction, fitness equipment and other fields. In the past few years, it has developed rapidly. [0003] The existing production method of composite pipe fittings is to form polymer composite materials into sheets, and pre-stack several sheets of co...
