Description
Technical field
The present invention relates to a kind of composite material taper equal thickness electric pole and its production methods.
Background technology
Wrapping formed is a kind of very important technique in composite molding, and Wrapping formed obtained composite material has
The excellent performance such as high intensity, low-density has extensive use in fields such as pipeline, pressure vessel, aerospaces.It is wound in
Type can be divided into thermosetting property winding and thermoplasticity winding again according to the different of matrix, and thermosetting property has been wrapped in the developing history in China
Through having decades, winding process and equipment all comparative maturities.But thermosetting property winding is thermosetting material due to its resin matrix
Material so that the material is in environmental protection and shock resistance etc. is short of, at the same time, as country is multiple to high-performance novel
Condensation material and environment-friendly products are greatly developed, and thermoplasticity winding will have wide development space.
Because of the up-small and down-big reason of tapered electric pole, but because be from small end to big end when longitudinal fiber is laid etc. quantity because
Element is inevitably formed during manufacturing：Longitudinal fiber forms big surface density in small end, and small surface density is formed in big end.
As a result it is that small end thickness is big to ultimately form product, the small product of big end thickness.Product in due to being that big end is fixed on ground,
Small end bears the pulling force of cable, so big end torque is big, small end torque is small.This is very unreasonable situation.
Invention content
The purpose of the present invention is to overcome the above shortcomings and to provide reasonable design, big end that when use withstands forces and small end
A kind of composite material taper equal thickness electric pole and its production method of the consistency of thickness of work fiber.
The object of the present invention is achieved like this：
A kind of composite material taper equal thickness electric pole, it includes big end and small end, the outer surface use cone of big end and small end
The interlude transition in shape face, the wall thickness of the big end, small end and interlude are consistent.
The thickness of circumferential fibrous layer from big end to small end is gradually thinned, and the thickness of longitudinal fiber layer gradually increases.
A kind of production method of composite material taper equal thickness electric pole：
Step 1: calculating product small end circumferential direction overlay thickness
Small end circumferential direction overlay thickness=pre-set product thickness-small end longitudinal fiber overlay thickness,
The surface density of small end circumferential direction laying yarn sheet width=standard yarn sheet width/(density of material * small end circumferential directions laying is thick
Degree)；
After known small end circumferential direction laying yarn sheet width, then screw pitch and yarn sheet width by changing circumferential fiber are needed
The circumferential overlay thickness wanted；
Above-mentioned screw pitch realizes that above-mentioned yarn sheet width is realized by change conductive filament head angle by the program setting of PLC；
Step 2: calculating product big end circumferential direction overlay thickness
Big end circumferential direction overlay thickness=pre-set product thickness-big end longitudinal fiber overlay thickness,
The surface density of big end circumferential direction laying yarn sheet width=standard yarn sheet width/(density of material * big end circumferential directions laying is thick
Degree)；
After known big end circumferential direction laying yarn sheet width, then screw pitch and yarn sheet width by changing circumferential fiber are needed
The circumferential overlay thickness wanted；
Above-mentioned screw pitch realizes that above-mentioned yarn sheet width is realized by change conductive filament head angle by the program setting of PLC；
Step 3: calculating product interlude circumferential direction overlay thickness
Due to basis between small end circumferential direction laying, the circumferential overlay thickness of interlude and thickness big end circumferential direction overlay thickness
Product space linear change, therefore obtain after small end circumferential direction overlay thickness and big end circumferential direction overlay thickness according to specific interlude
Position the circumferential overlay thickness of interlude can be calculated；
Step 4: when production, adjusting control PLC program adjusts corresponding position parameter.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of composite material taper equal thickness electric pole of the present invention and its production method do not change the feelings of quantity in longitudinal fiber
Under condition, change the surface density of circumferential fiber, the longitudinal fiber thickness for finally obtaining small end adds circumferential fiber thickness to be equal to big end
Longitudinal fiber thickness adds circumferential fiber thickness, and the consistency of thickness of the big end for the product for being and the work fiber of small end improves production
Quality.
