Abstract
The invention relates to a double-injection sleeve and a machining technology. The double-injection sleeve comprises a large-head end and a small-head end; a quincuncial hole is formed in the end face of the large-head end; an annular texture is arranged on the surface of the large-head end; a rectangular hole is formed in the end face of the small-head end; the machining technology comprises an earlier stage processing technology and an electroplated machining technology; chromium plating parameters are adjusted, and therefore the color difference sense between the shiny surface and the matt surface of the sleeve is strong; the shiny surface is smooth and flat; the overall anti-rust capability of the sleeve is improved, and the service life of the sleeve is prolonged; and due to the design of the surface texture, the shiny surface and the matt surface are remarkably separated. The double-injection sleeve is stable in structure, excellent in performance and suitable for large-scale popularization.
Description
Technical field
The present invention relates to double-colored sleeve, particularly relate to a kind of double-colored sleeve and processing technology.
Background technology
Double-colored sleeve is box spanner important composition parts, plays the effect of connection and driving force, uses frequent in the daily production operation of people.It is simple that it has structure, easy to use, the advantage that transmission efficiency is high.Can various operating environment be adapted to, be particularly useful for twisting bolt or the nut of the very narrow and small or very depths of caving in, status.When operating the nut of different size or bolt, the double-colored sleeve engagement sleeves barrel spanner of dimension is selected to fulfil assignment.
Double-colored sleeve comprises minute surface and cloudy surface two parts, and qualified double-colored cylinder mirror portion, its any surface finish is smooth, free from admixture, crackle.Need to use electroplating technology when actual production, this technique is the critical process that double-colored of impact finally becomes chromatic effect, the electroplating technology effect of the double-colored sleeve of tradition is undesirable, the aberration of minute surface and cloudy surface is little, boundary is unclear, and people easily produce the collimation error when selecting use, affects operating efficiency, surface gets rusty easily, and then affects service life.
Summary of the invention
For the present situation of above-mentioned prior art, technical problem to be solved by this invention is to provide a kind of Stability Analysis of Structures, and minute surface and cloudy surface are demarcated obviously, and aberration sense is strong, and double-colored sleeve processing technology that can be antirust.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of double-colored sleeve, comprises large women's head-ornaments and little women's head-ornaments, and this stub end end face is provided with plum blossom hole, and stub end side is provided with annular texture, and this little head end end face is provided with rectangular opening.
A kind of double-colored sleeve processing technology, the processing technology of described double-colored sleeve comprises process in early stage and electroplating processing process.
Further, described electroplating processing process comprises pre-electroplating treatment and plating line.
Further, described pre-electroplating treatment comprises following steps:
A, to deoil: except surface and oil contaminant, use normal temperature degreaser, the time is 10-20 minute;
B, washing: spray washing;
C, activation: use hydrochloric acid, time 2-8 minute;
D, washing: spray washing;
E, change are thrown: use and bore industry polishing powder, the time is 20-150 second;
F, washing, spray washing;
G, antirust: NaOH or natrium nitrosum.
Further, plating line comprises following steps:
A, upper hanger: by work piece on hanger;
B, cleaning: spray washing;
C, activation: use hydrochloric acid, time 2-8 minute;
D, half light nickel: time 5-20 minute;
E, bright nickel: time 5-15 minute;
F, recovery;
G, cleaning: spray washing;
H, nickel plating: time 15-150 second;
I, recovery;
J, cleaning: spray washing;
K, lower hanger.
Compared with prior art, the invention has the advantages that: by adjustment chromium plating parameter, make sleeve minute surface and the sense of cloudy surface aberration strongly, minute surface is bright and clean smooth, and promote the overall antirust ability of sleeve, lengthening sleeve service life, in addition, the design of superficial makings, minute surface cloudy surface is made to demarcate obviously, Stability Analysis of Structures of the present invention, excellent performance, is applicable to large-scale promotion.
