Abstract
The utility model discloses a rotor combined element which is used on an air spinning spinner, wherein a layer of tungsten carbide with 0.5-2.0mm thickness is seeped on a rotor rod, and the combined element of the rotor rod and a rotor adopts the interference fitness tight connection. The utility model significantly simplifies the production technique of a common rotor combined element, increases the hardness and abrasion resistance of the rotor rod, reduces the production cost, and meets the long service life requirements of the rotor combined element in the production process of the spinner.
Description
Technical field
The utility model relates to the parts on a kind of open-end spinning frame (also claiming rotor spinning machine), specifically a kind of revolving cup conjunction, and it is applicable to the pellet type revolving cup.
Background technology
The revolving cup bar of used revolving cup component is Buddha's warrior attendant plating again after the employing boronising on the existing open-end spinning frame, the manufacturing cost height, and need depend on import, the price height, and homemade revolving cup bar is because of the defective of boronizing technology, Buddha's warrior attendant plating and process materials aspect, cause the hardness of revolving cup bar easily and wear no resistance, just wear and tear after the use of short time, service life is shorter.
Summary of the invention
The utility model is exactly that will to overcome the existing revolving cup bar hardness of domestic production not enough, the shortcoming that wears no resistance, overcome the high defective of external import revolving cup bar price simultaneously, a kind of revolving cup conjunction is provided, on the revolving cup bar, annotate and ooze hardness and the ABRASION RESISTANCE that the thick carbide layers of 1.7mm increases the revolving cup bar, reach the effect that prolongs revolving cup bar service life and reduce production costs.In addition, the utility model has adopted a compression moulding of revolving cup bar and revolving cup interference fit for overcoming between revolving cup bar and the revolving cup in conjunction with untight defective.
The utility model is for improving the hardness and the ABRASION RESISTANCE of revolving cup bar, take following technical scheme to realize: at first with ordinary carbon steel or steel alloy car system revolving cup bar blank, revolving cup bar blank and tungsten material are put into an airtight bulge, vacuumize, applying argon gas is to 0.1Pa, carry out glow discharge with airtight cylinder as negative electrode, the ionization in discharge process of tungsten material produces tungsten ion, be diffused in the revolving cup bar matrix, at last infiltration revolving cup bar is carried out carbonization treatment, make revolving cup bar surface form the thick carburization zone of one deck 1.7mm and annotate infiltration layer, the revolving cup bar that notes are impregnated with the charing tungsten layer cleans decontamination with gasoline or kerosene and handles, and combines closely into the revolving cup conjunction after the deformation place of revolving cup bar 1 in annotating the infiltrate journey carried out reconditioning processing back and revolving cup 2 adopts interference fit to suppress.
The revolving cup conjunction that utilizes the utility model to make has following beneficial effect: easy to make, with low cost, ABRASION RESISTANCE is good, ABRASION RESISTANCE improves at least 2 times than domestic existing revolving cup bar, reach equal wear resistance level with the revolving cup bar of external import and cost reduces by more than 50, satisfied the long-life requirement in the spinning machine production process.

The specific embodiment
Below in conjunction with example the utility model is specifically described:
Adopt ordinary carbon steel or steel alloy car system revolving cup bar blank 1, regrind and cut revolving cup bar cylindrical and its roughness is reached or be higher than Ra0.8, revolving cup bar blank and tungsten material are put into an airtight bulge, vacuumize, applying argon gas is to 0.1Pa, carry out glow discharge with airtight cylinder as negative electrode and produce tungsten ion, tungsten ion is made a bet in the effect of discharge electric field and is infiltrated in the revolving cup bar matrix, the notes time of oozing is 3～4 hours, the revolving cup bar that then notes is impregnated with tungsten forms the charing tungsten layer 1000 ℃ of following charings 2 hours.The hardened layer 1-2 that measures tungsten carbide tool is 1.2mm, tungsten carbide tool enriched layer 1-1 thickness is 0.5mm, total tungsten carbide tool layer thickness 1.7mm, hardness HRC62, the revolving cup bar that notes ooze the charing tungsten layer cleans after decontamination handles with gasoline or kerosene, the deformation place of revolving cup bar in annotating the infiltrate journey carried out reconditioning repair, last revolving cup bar adopts the compacting of H6/r5 interference fit to combine closely into the revolving cup conjunction with revolving cup.
Claims (3)
1, a kind of revolving cup conjunction is made up of revolving cup bar (1) and revolving cup (2), it is characterized in that described revolving cup bar surface notes are impregnated with the charing tungsten layer.
2, revolving cup conjunction according to claim 1 is characterized in that it is 1.7mm that the tungsten carbide tool layer thickness that oozes is annotated on revolving cup bar surface.
3, revolving cup conjunction according to claim 1 is characterized in that interference fit is adopted in the combination of revolving cup bar and revolving cup.
