Abstract
The present invention is one novel weaving steel heald with alloy surface. The steel heald is manufactured by alloying the surface of common steel heald. The alloy layer has high hardness, high wear resistance, good lubricant performance and high anticorrosive property, so that the steel heald of the present invention has increased service life.
Description
It is the vitals of loom warp thread that steel is combined.
Shown in figure (1), in the loom running, to sum up descend the forward travel of reciprocating motion and yarn by the what steel, produce the intense attrition of the comprehensive and yarn of steel.On industrial production, by this intense attrition of what, steel is combined using three months to half a year, combines guidewire port at steel, i.e. the breach (or fast mouthful) of formation shown in figure (2) cause frequent broken string, and it is comprehensive to need more to renew steel again.Like this, not only influence the quality of product, increased weaver's labour intensity, and increased production cost, reduced labor productivity.Above-mentioned situation to the modern loom fast of what, influences even more serious.
Generally, the production that steel is combined is to adopt elastic alloy steel or ordinary carbon steel through punching press, and quenching forms.Yet, use the prepared steel of these class steel to combine by traditional method, by wearing no resistance of what base material, be difficult to bear the intense attrition that yarn is combined steel, thereby cause the quick formation of breach.
Prolong the long wire heald method in service life as solution, people can adopt high strength, highly wear-resisting alloy steel, yet, this has not only increased steel and has combined the production difficulty that factory's steel is combined, and, use such steel to combine for the weaving mill that every loom of what is combined with regard to up to ten thousand steel of need, just need pay the high cost that increases cost.
The present invention finds through long-term experiment, need not use high strength, the high-wearing feature steel alloy is made steel and is combined, only ordinary steel must be combined, handle through surface alloying process provided by the present invention, the surface that steel is combined forms alloy-layer, can delay the formation that steel is combined breach greatly, prolongs the service life of long wire heald exponentially.
The above-mentioned discovery of prison what, the present invention proposes a kind of combining with ordinary steel handles through surface alloying, combine the surface alloying layer of surface formation shown in figure (3) at steel, thereby form novel high-wearing feature weaving steel heald with alloy surface and the production method thereof that a kind of different what conventional steel is combined.
The hardness of being combined surface alloying layer by the what steel can reach Vickers hardness more than 600, and anti-wear performance is good, thereby has delayed greatly to form and development with the breach that the steel of this alloy-layer surface bearing is combined, and has prolonged the service life that steel is combined.Simultaneously, have very high lubricity and corrosion stability by the what alloy-layer, combine thereby not only reduced yarn and steel, steel is combined with steel the friction between comprehensive, combines etch resistant properties in Weaving Shop but also can increase steel.By the increase of what case hardness, the stiffness that steel is combined also increases, thereby can reduce thickness and weight that steel is combined, reduces the production cost that steel is combined.
As the method that obtains surface alloying layer, the present invention is once to vacuum ion membrane plating, electro-deposition, the element heat leak, the displacement plating, all methods such as chemical deposition and alloy-layer performance thereof have been carried out many-sided investigation, and according to the size of investing, the difficulty or ease of operation, the impact analysis that the performance of alloy-layer is combined combination property to steel found that, use electro-deposition, the element heat leak, displacement plating, vacuum ion membrane plating, any method in the methods such as chemical deposition, or its combination, and be aided with pre-process and post-process, all can make steel combine the surface and form alloy-layer, and acquisition has certain degree of hardness, ABRASION RESISTANCE, the steel of lubricity and corrosion stability is combined, and preferably includes the element heat leak when using combined method.
The anti-wear performance that the composition of surface alloying layer is combined steel has significant effects.The present invention screens numerous elements in the periodic table, selects metallic element group Cr at last, Fe, Co, Ni, Ti and nonmetalloid group C, N, B, S, the element combinations in P two group elements is formed as the best of alloy-layer, thereby obtains the surface alloying layer of high comprehensive performance.And except above-mentioned element combinations, can add or not add other elements.
Except above-mentioned element combinations feature, the present invention also contrasts the ratio of metallic element and nonmetalloid, confirms that nonmetalloid optimum weight content in alloy-layer is 0～30%, is preferably 0～20%.
Combine according to steel that the present invention obtained, not only delayed the formation that steel is combined breach greatly, prolonged steel and combined service life, and, reduced the friction between steel is combined simultaneously, improved the etch resistant properties that steel is combined by the good lubricity and the corrosion stability of what alloy-layer.It implements Comparative Examples as showing (1):
Table (1) is implemented Comparative Examples
| Steel is combined type | Hardness (Hv) | The formation 0.1mm breach time (my god) | General service time (moon) |
| Ordinary steel is combined | ????500-550 | ????30 | ????3-6 |
| The surface alloying steel is combined | ????＞600 | ????150 | ????＞24 |
Claims (4)
1. the invention provides a kind of common Weaving steel and combine through the surface alloying processing, and good novel surface weaving steel heald with alloy and the production method thereof of a kind of abrasion resistance that obtains.
2. according to claim 1, it can be electro-deposition that steel is combined the surface alloying process, vacuum ion membrane plating, element heat leak, displacement plating, the combination of one or more in the methods such as chemical deposition.But preferably include the element heat leak.
