Description
[technical field]
The present invention relates to a kind of manufacture method of strengthening ring for commutator.
[background technology]
Commutator is applicable to universal motor, and its structure is to be formed alternately by commutator segment and mica sheet, because the temperature rise behind the motor high speed rotating makes the commutator of known technology be difficult to bear the normally operation under the environment of high-speed and high-temperature of huge centrifugal force.
In order to overcome deficiency of the prior art, people try one's best and improve the quality and the useful life of commutator, have also obtained certain effect.Look into Chinese patent, its patent No. just provides the steel reinforcing ring has been set on the commutator medial axis for 99103798.7, but this steel reinforcing ring easily and commutator be short-circuited.Looking into the patent No. is the commutator of 96180521.8 band reinforcing rings, is to constitute knockdown stiffening device by becket and dead ring, should be more satisfactory, but the processing technology complexity.Looking into the patent No. is 02112020.X, name is called the patent of " manufacture method of high-strength stiffening ring of commutator ", it discloses following content: " a kind of manufacture method of high-strength stiffening ring of commutator; prescription is weighed with weight; it is characterized in that: selecting dilution F51 epoxy resin for use is that raw material is weighed as 1; add 304 liquid curing agent 60～80% again, fully stirs and makes the reinforcing ring resin; On the screwed rod in two ends, tightly overlap the thin slice that requirement is made by metal material again, the width of thin slice equals the width of desire processing reinforcing ring, and with nut all thin slices is tightened to one at the rod end; Selecting the E27/3 non-alkali yarn for use is that raw material is weighed as 1, be immersed in the groove that ring winding machine is added with 50～70% reinforcing ring resins, the non-alkali yarn that will contain the reinforcing ring resin through ring winding machine automatically is around being with thin slice and becoming flake rod with nut on the screwed rod in fastening good two ends to aforementioned, again the flake rod that winds was put into baking oven 3～12 hours, temperature is controlled at 80～250 ℃; The flake rod of oven dry is taken out from baking oven, after the cooling, processed, polish, unclamp flake rod then, the reinforcing ring that makes is taken out with the machining equipment outer surface."; this manufacture method; because what adopt is 304 curing agent; described 304 curing agent are that raw material makes through condensation, addition reaction with aliphatic cyclic amine TAC; it and epoxy resin cure; though thermal discharge is lower, also heating curable, the electrical property of its solidfied material, chemical property and physical and mechanical properties still do not reach requirement; This manufacture method adopts the E27/3 alkali-free glass fibre yarn, and its ultimate strength is less, thereby its tensile strength of reinforcing ring product that makes is also lower; Particularly with flake rod in the process of curing, employing be that single-point is heated, that is to say with stationary temperature to cure that the reinforcing ring product resistance to elevated temperatures that it obtains is relatively poor.
[summary of the invention]
In view of the resulting reinforcing ring product of the high-strength stiffening ring of commutator manufacture method in the background technology has above-mentioned deficiency, the technical problem to be solved in the present invention provides a kind of manufacture method of strengthening ring for commutator, makes the reinforcing ring product heat resistance that obtains good and tensile strength is high.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme to finish: a kind of manufacture method of high-temperature-resisting reinforced ring of commutator, and prescription is weighed with weight, it is characterized in that this manufacture method has following steps:
1) 8～10 parts of F51 epoxy resin, 4～8 parts in 504 curing agent and the titanium dioxide that takes by weighing dilution is raw material for 0.4～1 part;
2) raw material in the step 1) is fully mixed together, and place it in the charge groove of ring winding machine, add 30～80 ℃ of hot mixts; Then
3) select the SC8-960 alkali-free glass fibre yarn for use, this glass fiber yarn be immersed in step 2) in mixture in;
4) alkali-free glass fibre yarn that contains epoxy resin composition after will soaking is with the reinforcing ring mould coiled flake rod on the ring winding machine; Then
5) flake rod being placed in the baking oven temperature increases progressively at times step by step and cures, described temperature increases progressively at times step by step cures, promptly be at first temperature to be controlled at 80 ℃ to cure 1 hour, temperature being elevated to 150 ℃ cured 1 hour again, again temperature is increased to 200 ℃ and cured 2 hours, at last temperature is elevated to 240 ℃ and cured 3 hours; After the cooling
6) metal bar of flake rod from ring winding machine broken away from, flake rod process punch press punching the becoming commutator strengthening ring semi-finished product after breaking away from;
7) with the polishing of commutator strengthening ring semi-finished product process, size; At last
8) reinforcing ring of turning being put into again in the baking oven temperature increases progressively at times step by step and cures, at first temperature being controlled at 150 ℃ cured 1 hour, temperature is elevated to 200 ℃ cured 2 hours, temperature being elevated to 250 ℃ cured 2 hours again, at last temperature is elevated to 280 ℃ cure 3 hours after, take out and promptly to get the commutator strengthening ring product.
Preferably, above-mentioned composition of raw materials takes by weighing 10 parts for the F51 epoxy resin of dilution, and 504 curing agent take by weighing 6 parts, and titanium dioxide takes by weighing 0.6 part.
In the above-mentioned manufacture method, owing to adopted 504 curing agent, 504 curing agent are modified methyl tetrahydrophthalic anhydride, solidifying point is low, the exothermic heat of reaction temperature is extremely low, thereby its solidfied material is that the reinforcing ring product has good electrical property, chemical property and physical and mechanical properties are arranged, adopted the SC8-960 alkali-free glass fibre yarn simultaneously, because the ultimate strength of SC8-960 alkali-free glass fibre yarn itself is greater than 350 Ns, so adopting this alkali-free glass fibre yarn is that prepared its tensile strength of reinforcing ring product of raw material is high especially; Simultaneously, in its manufacture method, utilize temperature to increase progressively the method for curing at times step by step, changed the physical property of reinforcing ring product, improved its heat resistance greatly, through test, its tensile strength reaches 800Kg/cm
2, high temperature resistantly reach 350 ℃.Compare with the reinforcing ring in the background technology, very big breakthrough is all arranged.
