Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
Its step of technical scheme that the present invention adopts is as follows:
(1) on metal-cored, groove and termination chamfering is processed;
(2) with fluoroplastics heat-shrinkable tubes metal-cored coated, two ends are being sealed, ensure metal-cored can not seepage;
(3) coated good metal-cored mold injection of putting into is gone out " ten " font holder part; (4) be support with support, injection moulding secondary is coated;
(5) adopt the welding manner such as ultrasonic wave or hot plate, send out protruding support section rivet welding, in aggregates with outer layer plastic structure.
In processing step of the present invention (1), the chamfering of metallic rod termination is the intensity increasing end portion.
In processing step of the present invention (2), adopt the fluoroplastics heat-shrinkable tube that Thickness Ratio is thicker, fluoroplastics can be the heat-shrinkable tubes such as PVDF, PFA, ETFE, FEP, ECTFE, and the fusing point of this material is higher than the plastics fusing point of outer cladding.
In processing step of the present invention (2), inner heating or other mode of heating be adopted, the complete melting in the two ends of plastic tube is welded again, also can use the plug consistent with collapsible tube material, then heating makes collapsible tube and plug be connected, and makes it seal;
In processing step of the present invention (3), at metallic rod trench portions injection moulding support section, after injection moulding completes, holder part diameter and metallic rod diameter want consistent;
In processing step of the present invention (4), the coated plastics of injection moulding secondary will lower than holder part;
In 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 is coated can increase, and such pull bar diametric(al) is oval, use during ultrasonic bonding and can be connected with support section better, intensity increases;
In processing step of the present invention (4), coating plastic is the good material of corrosion resistance normally, such as PVDF, PFA, ETFE, FEP, ECTFE, PP etc.In order to increase material weldability, usually increase glass fibre or carbon black etc. in the material.
In processing step of the present invention (5), during rivet welding, whole support to be done in the metal-cored bottom after injection moulding secondary is coated, to avoid welding, product be damaged.
The present invention also comprises and a kind ofly adopts plastics entirely coated and have the processing technology of the corrosion resistant metal bar of distinctive appearance.One of this processing technology application is the pull bar of large scale assembling silicon chip flower basket.Large scale assembling silicon chip flower basket, its structure is 2 side plates, and have some pull bars (such as 6,5 etc.) in the middle of side plate, has metallic strength member, metal-cored outer cladding plastics in the middle of pull bar, a lot of teeth of plastics profile are used to fixing silicon chip.An other application of this technique is corrosion resistant equipment, the power transmission shaft of such as chain type Wafer Cleaning, the agitator, supporting traverse etc. of reactor.Also have reinforcement metal core in the middle of them, contour structures is complicated.
This technique is that the metal-cored mould of putting into of coated good plastics is injected support section, then is support the overall pull bar of quadric injection mould with support section.Support portion branch exceeds injection moulding appearance, smooth with ultrasonic wave rivet welding, makes support section and appearance plastics be linked to be entirety.
This processes product can be the pull bar of the gaily decorated basket, pull bar together with end plate welding, is made into the gaily decorated basket, is applicable to various corrosive environment, as hydrofluoric acid, the concentrated sulfuric acid etc.; Also can using this pull bar and other equipment connection as support member, the such as power transmission shaft of chain type Wafer Cleaning, the agitator etc. of reactor.Because there be the metal-cored of strong support in the middle of converted products, have good intensity, the plastics of outside can prevent the intrusion of corrosive liquid.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
