Abstract
Umbrella frame umbrella bar material of the present invention is a kind of glass fiber reinforced plastic shapes that is made of glass fiber strand and injection moulding integument, described umbrella frame parts preparation method be a kind of be core rod with the fiberglass umbrella frame, injection moulding forms additional member, and finishes the method for umbrella frame parts assembling.This umbrella frame umbrella bar material proportion is little, not corrosion, and after the autofrettage of glass fiber strand drawn, the rigidity of section bar and elasticity improve.This method makes umbrella rib structure integrated, and each member connects fastness and improves, and therefore, adopts this umbrella frame umbrella bar material and method; Not only can make parachute kit lightness, attractive in appearanceization, improve the class of product, and can enhance productivity greatly.
Description
The method that the present invention relates to a kind of umbrella frame umbrella bar material and make the umbrella frame parts.
The system umbrella is already made the material of umbrella frame umbrella bar, and major part also adopts steel wire and steel pipe at present, and in the use, there are four problems in steel wire umbrella frame and steel tube umbrella pole: the one, and the antirust processing cost height of steel wire steel tube surface, in case the top layer is destroyed, umbrella frame still can corrosion; The 2nd, the rigidity of steel wire is weak, poor flexibility, and easy deformation influences the attractive in appearance of parachute kit; The 3rd, the Heavy Weight of umbrella frame umbrella bar, parachute kit seem not light and handy; The 4th, thunderstorm season uses dangerous.
The objective of the invention is for the system umbrella provides already that a kind of in light weight, rigidity is strong, good springiness, lightning-arrest electricity, and the umbrella frame umbrella bar material of not corrosion and when adopting this umbrella frame material, the preparation method of umbrella frame parts.
This umbrella frame umbrella bar material is a glass fiber reinforced plastic shapes, and its architectural feature constitutes by having the injection moulding integument that stretching Yu Ying Li And becomes the glass fiber of boundling shape and resin and filler to form.
The umbrella frame parts are made up of umbrella frame and additional member, the preparation method of umbrella frame parts is: the position making groove that additional member at first is installed at the fiberglass umbrella frame, then the trench portions of umbrella frame is put in the pattern of additional member, make core rod with the fiberglass umbrella frame, injecting high-intensity plastics in pattern, is the cooling mould unloading at last.
The accompanying drawing of this specification has:
Fig. 1: fiberglass umbrella frame material structure figure;
Fig. 2: fiberglass umbrella bar material structure chart;
Fig. 3: long umbrella rib modular construction figure;
Fig. 4: short umbrella frame modular construction figure;
Fig. 5: umbrella frame parts preparation method step 1 figure.
Accompanying drawing has been expressed content ， And of the present invention and has been specifically described embodiments of the invention.
Fiberglass umbrella frame and umbrella bar are made on wire drawing pattern machine; with glass fiber La Shen And boundling; make glass fiber (1) before injection moulding, have stretching prestressing force; in the mould of placing pencil glass fiber (1), inject high-intensity resin and filler then; form injection moulding integument (2), so promptly made fiberglass umbrella frame and umbrella bar.Round material is made umbrella frame, and pipe profile is made the umbrella bar.
The umbrella frame of parachute kit divides long umbrella rib and short umbrella frame, the long umbrella rib parts are by long umbrella rib (3), joint (4) and saddle (5) are formed, joint (4) and saddle (5) are additional member, be located at the end and the middle suitable position of long umbrella rib (3) respectively: short umbrella frame parts are made up of short umbrella frame (6) and joint (7), joint (7) is an additional member, be located at two of short umbrella frame (6), the long umbrella rib parts are the same with the preparation method of short umbrella frame parts, at first make groove (8) at the position of umbrella frame erection joint (4 or 7) and saddle (5), be that umbrella frame is put into joint mould or saddle mould then, follow the injection moulding ABS plastic, behind the cooling mould unloading, promptly obtain the umbrella frame parts.
Little (the 1.3-1.4 gram per centimeter of above-mentioned glass steel profile proportion3), can corrosion, non-conductive, but thunder-and lightning protection, after the long glass fibres tow drawn autofrettage of section bar core, rigidity and the elasticity of section bar are improved greatly, just make umbrella frame umbrella bar material with this glass die, saving steel has not only improved the performance of umbrella frame and umbrella bar, and make parachute kit lightness, attractive in appearanceization, improve the class of product. In addition, make the umbrella frame parts with the method for injection mo(u)lding assembling, both can make umbrella rib structure integrated, improve the connection fastness between each member, also can greatly enhance productivity.
Claims (2)
1, a kind of umbrella frame umbrella bar material is characterized in that: be a kind of by glass fiber (1) with stretching prestressing force ， And one-tenth boundling shape and the glass fiber reinforced plastic shapes that is made of the injection moulding integument (2) that resin and filler are formed.
2, a kind of preparation method of fiberglass umbrella frame parts, it is characterized in that: the position making groove (8) that additional member at first is installed at the fiberglass umbrella frame, then the trench portions of umbrella frame is put in the pattern of additional member, make core rod with the fiberglass umbrella frame, in pattern, inject high-intensity plastics, cool off mould unloading at last.
