Description
Technical field:
The utility model relates to part used on a kind of open-end spinning---and the textile machinery cup belongs to field of textile machinery.
Background technology:
At textile machine---the cup that open-end spinning uses is the critical component that compiles fiber, cohesion in the rotor spinning and close, twist resultant yarn, and it will adapt at a high speed, and the balance that turns round again guarantees evenly cohesion and twisting.Rotor spinning machine cup rotating speed is very high, and its centrifugal force is bigger, and the negative pressure in the cup is very high again, thereby the suffered air drag in twisting process of the yarn in the cup is also bigger.When fibrous ring also be in the yarn stage be stripped from leave the fibre-condensing groove after because its turn just just begun to form, so this moment, its anti-jamming capacity was very poor.If the brute force of yarn is less than the frictional resistance in the cup, air drag and be subjected to the influence of other factors, sliver promptly can produce broken end.Therefore, require cup in light weight, smooth surface had so both reduced the friction with air, reduced power consumption, and the fiber that helps entering cup again successfully enters collection surface along slide surface, and not yielding under the high speed rotary action of centrifugal force; More harsh is that requirement cup collection surface can stand the friction in the fiber resultant yarn process, guarantees its ABRASION RESISTANCE, delays the variation of collection surface shape and surface property.
At present, cup is many to be raw material with the aluminum alloy material, generally forms with LY12 or the turning of LC4 duralumin bar, and for reducing the wearing and tearing of cup, working face adopts hard anodized to handle; In addition, minority steel blank cup, working face adopt chemical Ni-P plating or composite chemical plating Ni-P-SiC coating to improve the abrasion resistance of cup inner surface, perhaps the collection surface place are carried out processing such as local boronising, carburizing, improve abrasion resistance.But adopt the cup of these conventional art means preparations, in the reality spinning is produced, usually find following situation:
(1) collection surface abrasion deformation.The geometry and the surface characteristics of wearing and tearing back collection surface change.The form of accumulating fiber bundle becomes irregular before the twisting resultant yarn, makes twist transmission, peels off, the mechanism of resultant yarn process is damaged, and spinning quality progressively worsens with the wearing and tearing of collection surface.Significantly reflected on this bar evenness, thickness joint and the end breakage rate at resultant yarn.
(2) slide surface surface abrasion.The surface treatment of this and material is closely related, and is not enough as case hardness, the impact of impurity in can't stand fiber, and behind the wildness, spinning just can not be carried out smoothly.
(3), make the very difficulty of peeling off of the cotton fiber that is embedded in the fibre-condensing groove because cup exceeds the time limit to use or improper use causes oxide layer in the fibre-condensing groove or coating to peel off easily to become coarse.This situation has been destroyed the contact power between yarn and has been increased the difficulty that turn forms and transmits, and sliver can not produce broken end when the brute force of yarn overcomes the frictional resistance of fibre-condensing groove.
(4) cup top mouth is damaged.The cup mouth is easy to generate and the proportional slub yarn of cup circumference if any indenture or rounding not.
Because cup is in Frotteurism in the course of the work, various fatigue wears easily take place, it is uneven to reach the very fast appearance of slippage working surface near the cup collection surface, this can cause yarn tension to be undergone mutation, make textiles flaws such as broken end, bar evenness difference occur, reduced the quality of textile product.
In order to ensure the quality of textile product, need often to change cup.General cup uses will be repaired once in about 6 to 10 months, used and upgraded to a year and a half in 12 months.Owing to the life cycle weak point, cause spinning shortening stationary phase, product quality fluctuates variation greatly, and especially cup uses the later stage spinning quality to be difficult to assurance, the dried inequality of bar can occur, break end and increase.And new cup also needs a period of time " walking ripe " after installation, and during this " walked ripe ", the quality instability of textile product must be just can ordinary production through " walking ripe " after date.As can be seen, frequently changing cup makes production cost increase greatly.At present, have only half a year many average life of cup product.
The utility model content:
In order to improve the cup surface property, increase the service life, the utility model provides a kind of novel textile machinery cup, solves problems such as the surface property that has the cup existence of using in the textile machine now is low, service life is short.
The technical solution of the utility model is as follows:

In the utility model, ceramic coating formed by micro-arc oxidation (PEO) is set earlier at cup matrix working surface, more outside the layer chemical plating nanometer Ni-P alloy (EP).
The beneficial effects of the utility model are as follows:
1, the utility model is matrix with the alumina-base material, because the heat dispersion of alumina-base material is better than steel, therefore can reduce the cup heat fatigue degree of wear at work, weaken in the collection surface deposition of impurity in the fiber and, help prolonging the service life of cup and improve spinning quality the impact of working face.
2, the ceramic membrane on alumina-base material cup top layer has good surface property, makes yarn form more evenly rule, make the transmission of the yarn twist, peel off, resultant yarn is steady, continuous and smooth and easy.Through test, common steel cup surface composite plating microhardness is below the HV900, and surface roughness is for being preferably 0.05 μ m, and thickness of coating is no more than 20 μ m near the collection surface, and be 1 year average life; Conventional aluminium matter cup surface hard anode oxidation film microhardness is below the Hv500, and surface roughness is preferably 0.1 μ m, and oxide thickness is less than 5 μ m near the collection surface, and be 8 months average life; Alumina-base material cup surface microhardness of the present utility model is Hv1000, and surface roughness is 0.01 μ m, and composite film thickness can reach more than the 30 μ m near the collection surface, and be more than 4 years average life.
3, the raising of cup surface property can reduce the probability that broken end, the dried unequal flaw of bar appear in textiles, promotes the quality of textile product, and cup is promoted service life simultaneously, has reduced the maintenance frequency of textile machine, has reduced production cost.Wherein, main performance index is as follows: average brute force/powerful CV:307.3/6.7; The twist: 68.1; Twist inequality: 1.57; The uneven rate of weight: 2.21%; Bar is done CV:13.02; Km slubbing: 15; Km details: 19; Cotton knot: 12; The blackboard bar is done cotton assorted (cotton mixing/impurity): 24/45; Wu Site communique 5% level.
