Description
Technical field
The present invention relates to a kind of electric connector connector processing method, particularly relate to a kind of pin groups component processing method.
Background technology
Contact pin is a kind of common part of electric connector, also claims pin, is widely used in electron trade, but contact pin conventional is at present mostly adopt integral type processing method, and by its seriation, this brings great convenience to user.But this integral type contact pin processing method needs to carry out Drilling operation and external diameter processing, and processing cost is high, and waste of raw materials is large.Along with the fast development of modern electronics industry, the application of contact pin is increasingly extensive, so propose baptism to the processing cost of contact pin, the processing cost and the raw-material waste of minimizing that therefore how to reduce contact pin are vast machinery or electronic technology field urgent problem.
Summary of the invention
For solving the problem, the invention provides a kind of pin groups component processing method, achieving no waste mine processing, thus greatly cutting down finished cost.
The object of the invention is to be achieved by following technical solution.
A kind of pin groups component processing method, the method is that integral type contact pin is adopted segmental machining, and one section is sleeve pipe, another section is tailpin, tailpin adopts and directly bends shaping with the isometrical bar of sleeve pipe, and then two sections are linked into an integrated entity by riveted joint processing, and its process steps is as follows:
The processing of a, sleeve pipe: sleeve pipe adopts minor diameter capillary brass pipe to cut off, and remove cut-out burr, then process chamfering A and the chamfering B at sleeve pipe two ends;
The processing of b, tailpin: tailpin processing mainly comprises the processing of contracting bar, the chamfer machining of tailpin afterbody and the formed machining of tailpin sweep of head;
C, surface treatment: the sleeve pipe machined and tailpin are carried out gold-plated process;
D, crimping are shaped: after sleeve pipe and tailpin assembling, the two be crimped together by riveting method.
Described step a sleeve pipe adopts minor diameter capillary brass pipe to cut off on miniature precision lathe, and removes the burr after cutting off, and the chamfering A at sleeve pipe two ends and chamfering B adopts on small-size punching machine compressing with mould.
Contracting bar is carried out by crimp by thread rolling machine after being processed as and adopting blanking die to cut off in tailpin one end by the contracting bar of described step b head, thus reaches and finally require size.
The chamfer machining of described step b tailpin afterbody is for adopting pressing die that afterbody is compressing, and pressing die cavity shape by spark machined out.
Being configured as of described step b tailpin sweep adopts bending die drawing.
Carry out after described steps d sleeve pipe and tailpin are crimped together drawing and dial test, under the 40N pulling force of regulation, tailpin does not allow to deviate from from sleeve pipe.
The beneficial effects of the utility model are:
Compared with prior art, common contact pin is decomposed into sleeve pipe in the present invention and contact pin two parts carry out split type processing, has the following advantages:
(1) head changes barrel forms processing into, can greatly save material.
(2) sleeve pipe adopts the capillary brass pipe of customization, decreases the time of car endoporus, and hole size consistency improves, and cost of labor, cutter and lathe loss simultaneously reduces, and production efficiency is improved greatly.
(3) sleeve pipe two chamfer adopts punch press reaming, and process velocity is fast, and consistency is good.
(4) afterbody uses copper wire wire rod instead, adopts the method for extruding, punching press, completes processing and the bending forming of tail dimension, and achieve no waste mine processing, production cost reduces.
(5), after sleeve pipe and tailpin are riveted, connect reliable.
In sum, after connector pin changes split type processing into by integral type, achieve no waste mine processing, the raw materials consumption of contact pin is reduced greatly; Meanwhile, the processing of each part, realize primarily of punch press, production efficiency and quality conformance are improved; Therefore, the economic benefit that split-type structural produces is considerable.And the method is safe and reliable, easy to implement, successful, can be popularized and applied to various machinery, electron trade.
