The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with the specific embodiment, further set forth the present invention.
Its step of technical scheme that the present invention adopts is following:
(1) on metal-cored, processes groove and termination chamfering;
(2) with the fluoroplastics heat-shrinkable tube metal-cored coating, sealed at both ends, guarantee metal-cored can seepage;
(3) go out " ten " font holder part coating the good metal-cored mold injection of putting into; (4) with the support be support, the injection moulding secondary coats;
(5) adopt welding manners such as ultrasonic wave or hot plate, send out protruding support section rivet welding, constitute an integral body with outer layer plastic.
In the processing step of the present invention (1), the chamfering of Metallic rod termination is the intensity that increases end portion.
In the processing step of the present invention (2), adopt the thicker fluoroplastics heat-shrinkable tube of thickness, fluoroplastics can be heat-shrinkable tubes such as PVDF, PFA, ETFE, FEP, ECTFE, and the fusing point of this material will be higher than the outer plastics fusing point that coats.
In the processing step of the present invention (2), adopt inner heating or other mode of heating, the complete melting in two ends of plastic tube is welded again, also can use the plug consistent with the collapsible tube material, heating fuses collapsible tube and plug again, makes its sealing;
In the processing step of the present invention (3), at Metallic rod trench portions injection moulding support section, after injection moulding was accomplished, the holder part diameter wanted consistent with the Metallic rod diameter;
In the processing step of the present invention (4), the plastics that the injection moulding secondary coats will be lower than holder part;
In the processing step of the present invention (4); In order to increase the intensity of material, the parts of plastics diameter that the injection moulding secondary of holder orientation coats can increase, and the pull bar diametric(al) is oval like this; Can fuse with support section better when using ultrasonic bonding, intensity increases;
In the processing step of the present invention (4), coating plastic is corrosion resistance material preferably normally, such as PVDF, PFA, ETFE, FEP, ECTFE, PP etc.In order to increase the material weldability, in material, increase glass fibre or carbon black etc. usually.
In the processing step of the present invention (5), to do whole supports in the metal-cored bottom after the injection moulding secondary coats during rivet welding, product damaged to avoid welding.
The present invention also comprises a kind of processing technology that adopts plastics to coat entirely and have the corrosion resistant metal bar of distinctive appearance.One of this processing technology application is the pull bar of the large scale assembling silicon chip gaily decorated basket.The large scale assembling silicon chip gaily decorated basket, its structure is 2 distolateral plates, and some pull bars (such as 6,5 etc.) are arranged in the middle of the side plate, and the metal strengthening core is arranged in the middle of the pull bar, the metal-cored outer plastics that coat, a lot of teeth of plastics profile are to be used for fixing silicon chip.An other application of this technology is corrosion resistant equipment, the power transmission shaft that cleans such as the chain type silicon chip, the agitator of agitated reactor, supporting traverse etc.The reinforcement metal core is also arranged in the middle of them, and contour structures is complicated.
This technology is to inject support section to the metal-cored mould of putting into that has coated plastics, with the support section is again to support the whole pull bar of quadric injection mould.Support portion branch exceeds the injection moulding appearance, and is smooth with the ultrasonic wave rivet welding, makes support section and appearance plastics be linked to be integral body.
This processes product can be the pull bar of the gaily decorated basket, welds pull bar and end plate together, is made into the gaily decorated basket, is applicable to various corrosive environments, like hydrofluoric acid, the concentrated sulfuric acid etc.; Also can be connected this pull bar as support member with other equipment, such as the power transmission shaft of chain type silicon chip cleaning, the agitator of agitated reactor etc.Because in the middle of the converted products the metal-cored of strong support arranged, good intensity is arranged, the plastics of outside can prevent the intrusion of corrosive liquid.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
