Abstract
The invention discloses a centrifugal pressure casting process of a copper lining bearing. The centrifugal pressure casting process of the copper lining bearing comprises the following steps: firstly an outer circle of a shaft sleeve manufactured according to design is chamfered and cast bronze is added to an inner hole, and meanwhile borax and charcoal dust in a volume ratio of 2:1 are added; then steel plates with venting holes are welded at two ends of the shaft sleeve for sealing; the sealed shaft sleeve is placed in an electric furnace for heating, heat preservation and reheating, after the process of heat preservation, the shaft sleeve is taken out from the electric furnace in a state of maintaining a horizontal axis; then the shaft sleeve is sleeved and clamped on a taper clamp head of a casting machine, a copper liner is evenly solidified in the process of rotating, a cooling system is opened for cooling, the shaft sleeve is demounted after rotating back for 3 minutes in a cooling state, the steel plates at the two ends of the shaft sleeved are cut out by a cutting knife in a lathe, and centrifugal pressure casting of the copper lining bearing is completed. The centrifugal pressure casting process of a copper lining bearing has the advantages of being simple in process, reliable in quality, saving in copper materials, and high in efficiency.
Description
Technical field
The present invention relates to Machining Technology field, especially a kind of centrifugal casting technique of brass bearing.
Background technology
All power transmission shafts operated under high speed or heavy load, all require that its sliding bearing has certain bearing capacity, wearability and stationarity, in order to save axle bush material and reduce bearing volume, be generally all that axle bush is cast directly on brearing bore now, but use traditional moulding pouring procedure, need to strengthen bush thickness, also can cause the number of drawbacks such as pore, gage distortion, not only do not reach the object of saving axle bush material, and its process complexity falls behind, and is difficult to reach quality requirement.
Summary of the invention
The object of the present invention is to provide a kind of centrifugal casting technique of brass bearing, the bearing quality made by this technique is reliable.
Technical scheme of the present invention is: a kind of centrifugal casting technique of brass bearing, its step: first by by the sleeve outer circle chamfering manufactured and designed, its diameter of bore is determined by the external diameter equaling brass, and inner bore surface roughness is Ra10, and cleans endoporus with gasoline; Then in endoporus, add cast bronze, also add borax and charcoal powder that volume ratio is 2:1 simultaneously, need before borax adds dry through 100 DEG C and be incubated 20 ~ 30 minutes, need before charcoal powder adds dry through 320 DEG C and be incubated 20 ~ 30 minutes; Then the steel plate having air-vent of burn-oning at axle sleeve two ends respectively seals; The axle sleeve sealing mouth is put into electric furnace and be heated to 920 DEG C ± 10 DEG C, be incubated and be heated to 1100 DEG C ± 10 DEG C again after 40 ~ 50 minutes, after being incubated 40 ~ 45 minutes, axle sleeve takes out under the state keeping its axis horizontal from electric furnace; Again by axle sleeve clamping on the conical chuck of casting machine, in rotation, make brass obtain even solidification, open hydraulic means, make tailstock to left dislocation lifting axe cover, starter motor, drive main shaft and axle sleeve with 1400 ~ 1500 revs/min of revolutions, after having turned 15 ~ 35 seconds, open cooling system and cooled, turn round 3 minutes again under the state of cooling after, unloaded Lower shaft sleeve, lathe prescinds with cutter the steel plate at axle sleeve two ends, and the centrifugal casting technique of brass bearing completes.
The invention has the advantages that: technique is simple, reliable in quality, saving copper material, efficiency are high.
Accompanying drawing explanation
Fig. 1 is the centrifugal casting process equipment connection layout of a kind of brass bearing of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail: a kind of centrifugal casting technique of brass bearing, it is characterized in that: first by by the outer rounded corner of axle sleeve 6 manufactured and designed, its diameter of bore is according to large 2 ~ 6 ㎜ of the copper layer thickness car of brass 8, inner bore surface roughness is Ra10, and cleans endoporus with gasoline, then add in endoporus by poured into a mould volume computing and comprise the cast bronze ZQSnPb30 of the required weight of allowance, also adding 100 DEG C of boraxs of drying and 320 DEG C of charcoal powders of drying that volume ratio is 2:1 simultaneously, then the steel plate 4 having air-vent 9 of burn-oning at axle sleeve 6 two ends respectively seals, and the size of pore 9 should be advisable to ensure that the copper liquid melted does not overflow and can breathe freely, the axle sleeve 6 sealing mouth is put into electric furnace and is heated to 920 DEG C ± 10 DEG C, be incubated and be heated to 1100 DEG C ± 10 DEG C again after 40 ~ 50 minutes, after being incubated 40 ~ 45 minutes, from electric furnace, level is taken out, by on the conical chuck 5 of axle sleeve 6 clamping on casting machine 2, brass 8 is solidified again, its process of setting is: open hydraulic means 11, tailstock 10 is moved to the left, thus hold out against axle sleeve 6, restart motor 1, motor 1 drives main shaft 3, conical chuck 5 and axle sleeve 6 turn round with 1400 ~ 1500r/min, liquid brass 8 is in this pivotal process, under the influence of centrifugal force, got rid of equably and solidify stick to axle sleeve 6 inner hole wall on, after having turned 15 ~ 35 seconds, open cooling system 7 to cool, Lower shaft sleeve 6 is unloaded turn round 3 minutes again under the state of cooling after, lathe prescinds with cutter the steel plate 4 at axle sleeve 6 two ends, the centrifugal casting technique of brass bearing completes.
