Description
Technical field
The present invention relates to the production technical field of ball pen, and in particular to a kind of production technology for ball-pen point.
Background technology
3000 Duo Jiazhibi enterprises, more than 20 ten thousand working populations, produce per year ball pen more than 380 hundred million ... China has become system
Big country, but a succession of numeral is behind, is the embarrassment that core technology and material height dependence on import, fake products inferior spread unchecked
Situation, the ball of substantial amounts of ball-pen point and for supporting the ball seat of ball to also need to import causes the ball pen of the country
Cost is increased substantially.
The ball and ball seat of current import, use hard alloy and stainless steel, are manufactured and justified by Pattern In Grinding Cemented Carbide
Pearl, then prepares ball seat by the cutting of stainless steel, because hard alloy steel has good wearability and corrosion resistance, so
Obtained ball pen life-span and fluency are preferable.But, because the hardness of hard alloy steel is larger, grinding is more difficult, China
Current grinding technique is difficult to reach requirement, and the price of hard alloy and stainless steel is higher.Also there is Some Enterprises selection in China
Oneself production ball and ball seat, the common alloy steel of use, this material Cutting free are cheap, but hardness is not enough, variable
Shape, and be easily corroded, so causing the ball of domestic ball pens many at present easily to drop, greatly shorten the use longevity of ball pen
Life.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of production cost is low, hard
Spend, the production technology for ball-pen point that decay resistance is high.
The purpose of the present invention can be achieved through the following technical solutions：A kind of production technology for ball-pen point,
The technique includes following steps：
(1) common alloy steel is cut into ball and ball seat, and sorting placement；
(2) ball obtained by step (1) and ball seat are subjected to surface modification treatment, obtain hard ball and hard ball seat；
(3) top of written body will be arranged on after hard ball and the assembling of hard ball seat, ball-pen point is produced.
Because common alloy steel has free machining feature, and price is cheaper, thus use common alloy steel for
Raw material, can improve the cost of cutting.Then surface modification treatment is carried out to the ball and ball seat of the common alloy steel of shaping,
The hardness and corrosion resistance of product can be effectively improved, the quality of ball and ball seat is improved, the matter of final ball-pen point is lifted
Amount.
Containing one or more of alloying elements in Cr, Ti, Mn, V or Si in described common alloy steel, the alloy member
Total mass fraction≤10% of element.
Described surface modification treatment comprises the following steps：Ball and ball seat are placed in continuous modified gas environment
Row surface modification treatment, produces the hard ball and hard ball seat.
It is preferred that, described modified gas include NH3, CO, the one or more in hydrocarbon gas or boron-containing gas.
It is preferred that, the temperature of the surface modification treatment is 500~1000 DEG C, and processing time is 3~24h.
NH3It can decompose at high temperature and obtain the larger N atoms of activity, CO, hydrocarbon gas can be resolved at high temperature
The larger C atoms of activity, boron-containing gas is decomposed into the larger B atoms of activity at high temperature, and N atoms, C atoms or B atoms are logical
Cross and diffuse between the molecule of common alloy steel, and occur instead with Fe molecules therein and Cr molecules, Ti molecules, Mn molecules
Should, metal nitride, metal carbides or metal boride are generated, and the above-mentioned substance gradually extends internally from surface, and with
The passage of time, thickness becomes larger, metal nitride, metal carbides and metal boride be respectively provided with good hardness and
Corrosion resistance, so that the quality of hard ball and hard ball seat is greatly promoted.
Compared with prior art, beneficial effects of the present invention are embodied in：Using Cutting free and cheap common alloy
Steel is as raw material, and the cost for being processed into ball and ball seat is low, then carries out surface modification treatment to ball and ball seat, can carry significantly
The quality of high ball and ball seat, and processing cost is low, finally obtains the ball and ball seat of inexpensive high-quality, can large-scale application in circle
The production of pearl pen nib.
Embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out lower premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementations
Example.
