Abstract
The present invention relates to zinc alloy collecting ring for electric motor and its production. Compared with available collecting rings of copper and stainless steel, the said one is wear resistant, inexpensive and long in service life. The said collecting ring is produced through pressure diecasting and this results in simplified technological process and raised finished product rate.
Description
The present invention relates to a kind of motor with ring header and manufacture method thereof, particularly metallurgical with having reached the three-phase asynchronous motor of reusing, Zinc alloy collecting ring of using in the wound rotor three-phase asynchronous motor and manufacture method thereof.
Ring header is to be complementary with brush in the motor to be communicated with the important conductive component of the outer circuit of rotor and machine, mainly is made up of conducting ring, insulating plastics, lead-in wire three parts.Wherein the quality of conducting ring quality directly influences the effect of ring header.Past, what the material of manufacturing conducting ring was used is copper alloy, but copper material costs an arm and a leg, and wears no resistance the cost height, work-ing life is short, on January 25th, 1989, CN1030673A discloses " stainless steel collector ring " of our factory invention, though the ring header that this material is made can overcome all deficiencies of copper material basically, but made in the use at it in recent years, its some critical defect comes out gradually.The one, because itself interior tissue inhomogeneous, usually cause the imbalance of ring header three-phase resistance, in the installation operation process, often can't repair and scrap because of the flashing dross.In addition, stainless material is difficult for processing, is easy to generate crackle, the scrap rate height.
Making at present stainless steel collector ring has casting, forging or rolling etc. with the method for conducting ring, and these methods all need be made long tubular blank material earlier, are cut into monocycle after precision work again, and formality is numerous and diverse, and is time-consuming, and yield rate is very low, and overall economic efficiency is poor.
The present invention promptly is at the problems referred to above, and more superior ring header of a kind of over-all properties and manufacture method thereof are provided.
The present invention is to be raw material with the zinc alloy, once makes the monocycle blank of conducting ring by extrusion process, and through precision work, solder taul is pressed into insulating plastics, makes Zinc alloy collecting ring.
Ring header of the present invention had both had good electrical conductivity, wear resistance, and light specific gravity (being 2/3 of copper alloy, stainless 3/4), price low (be about copper 2/5), be easy to processing, homogeneous microstructure had both overcome the deficiency of copper material ring header, the three-phase imbalance of having avoided stainless steel collector ring to exist again, easily crack and mass defects such as flashing dross, prolonged the work-ing life of product widely.Simultaneously, owing to adopt extrusion process, its monocycle blank of making can be realized chipless or few smear metal processing, has simplified manufacturing procedure widely, has improved yield rate and production efficiency, and overall economic efficiency is significantly improved.
Fig. 1 is the ring header structural representation, and 1 is conducting ring, and 2 is insulating plastics, and 3 are lead-in wire.
Fig. 2 is the conducting ring parts drawing, and it is a garden ring body, inner diameter d, and outer diameter D, the size of high B is decided according to power of electric motor, rotating shaft size, can be processed into the product and the various electric drilling match of a series of different sizes.
Employed kirsite in the Zinc alloy collecting ring of the present invention is take zinc as primary raw material, Be aided with the elements such as aluminium, copper, magnesium and melt by a certain percentage and form, it is pointed out that and to select The preparation of the high raw material of purity must be selected aluminium ingot more than the 3# such as aluminium. If material purity is low, make Collector ring compactness is poor, easily debacle.
Zinc alloy collecting ring of the present invention manufacture method---the extrusion process of conducting ring, more The middle-size and small-size collector ring of suitable manufacturing.
Embodiment: elements such as zinc, aluminium, copper, magnesium are got material in following ratio, AL23-28%, Cu1.5-2.5%, Mg0.01-0.03%, impurity F e≤0.2%, pb≤0.03%, Cd≤0.02%, surplus is Zn.After then all batchings being melted in crucible oven or line frequency furnace, constantly make the single-piece blank with die casting interlock unit, make conducting ring 1 through precision work by Fig. 2, solder taul 3, be pressed into insulating plastics 2 promptly make a kind ofly conduct electricity very well, price is low, be easy to process, long service life, Zinc alloy collecting ring that overall economic efficiency is high.
Claims (3)
1. electric motor ring header, particularly metallurgical with and rise and reuse the ring header that three-phase asynchronous motor, wound rotor three-phase asynchronous motor are used, be made up of conducting ring (1), insulating plastics (2), lead-in wire (3), the material that it is characterized in that making conducting ring is a zinc alloy.
2. ring header according to claim 1 is characterized in that: the main composition (weight percent) of zinc alloy conducting ring is: AL23-28%, Cu1.5-2.5%, Mg0.01-0.03%, impurity F e≤0.2%, pb≤0.03%, Cd≤0.02%, surplus are Zn.
3. method of making claim 1 or 2 described ring headers comprising that batching dissolves system single-piece conducting ring finished product, solder taul, be pressed into insulating plastics etc., it is characterized in that adopting extrusion process once to make single-piece conducting ring blank, after precision work, make conducting ring again.
