Abstract
The present invention relates to a method for producing a commutator with a cold-extruded end surface, which is characterized in that circular copper wires are cut and are extruded by cold into a commutator blank; after cleaned, the commutator blank is pressed and injected to a shaping; the shaping is bent into a hook after turning and channeling processes. The commutator with a cold-extruded end surface, which is produced according to the method, has a simple manufacturing process and overcomes the problems of spark generation, high noise, etc. when a motor commutates in a commutator produced by transmission technique due to the asymmetry of corresponding commutating segments on a line. The commutator with a cold-extruded end surface, which is produced according to the present invention, has the advantages of short work hour, material saving and long service life, and compared with the prior art, the commutator with a cold-extruded end surface has outstanding substantive characteristics and marked progress.
Description
Technical field
The present invention relates to the invention of the manufacture method of commutator, being specifically related to is the whole invention of adopting cold extrusion method to manufacture end commutator of commutator.
Background technology
In the prior art, end commutator is the ladder row commutator segment group after four road drawing procedure moulding, in accordance with regulations behind the size stamping-out, by manual every ladder row commutator group interval a slice mica sheet is become a commutator by design sheet array, because the tolerance that in the drawing forming process, produces, add the tolerance of mica sheet thickness, must be that a slice is milled in a feed when milling mica slot, can not carry out diagonal angle two cloudlet grooves and once carry out groove milling, the processing technology complexity, the commutator segment that its manual commutator of forming is corresponding in twos is not symmetrical on same straight line, thereby cause carbon brush for electric machine to produce deviation when commutation, produce spark, noise increases, cause commutator minimizing in useful life, motor properties and then descends.
Summary of the invention
Problem in view of the known technology existence, purpose of the present invention aims to provide the simple science of a kind of technology, the saving working hour is the material saving again, institute's product processed long service life, and a kind of cold extrusion commutator production process of scientific structure and products thereof, for achieving the above object, the present invention finishes as follows: the manufacture method of this kind commutator with cold-pressed end face, it is characterized in that after the round copper wire cutting, carry out cold-extruded and be pressed into the commutator blank, with it injection-compression molding, after turning, groove milling, milling hook, last crotch forms after the cleaning; Described injection-compression molding process is to carry out extrusion modling filling up phenolic moulding powder in the cavity volume of blank; Described turning operation is the end commutator of moulding to be carried out inside and outside circle cut edge; The commutator with cold-pressed end face product that causes as stated above, during groove milling, end face is carried out five equilibrium, only need on the symmetrical five equilibrium straight line with a groove milling of milling cutter, overcome commutator that traditional handicraft is processed into because of the commutator segment of correspondence point-blank symmetry cause motor commutation the time produce spark, problem such as noise is big, and the useful life of improving commutator, effectively keeping motor properties simultaneously, is the quantum jump on the commutator production technology.Compared with prior art, have outstanding substantive distinguishing features and obvious improvement.
Description of drawings
The present invention has following accompanying drawing:
Fig. 1 is the cold-extruded blank end face structure figure of product of the present invention;
Fig. 2 is the cutaway view of the cold extrusion blank end face of product of the present invention;
Fig. 3 is the end face structure figure of product of the present invention;
Fig. 4 is the cross-sectional end view of product of the present invention;
Fig. 5 is a process chart of the present invention.
Embodiment
Accompanying drawing has been represented technological process of the present invention, further describe the process of embodiment below again in conjunction with theme of the present invention, the manufacture method of this commutator with cold-pressed end face, at first the steel wire of circle is cut by designing requirement, copper section after the cutting is placed on the cold extrusion press that mould is installed pushes, the existing commutator blank of copper section after the extruding (as Fig. 3), after this blank pickling, in the cavity volume of blank, insert phenolic moulding powder 3, be placed on and carry out injection-compression molding on the press injector, described injection-compression molding is that thermosetting phenolic moulding powder 3 and blank is agglomerated together, then its inside and outside circle being carried out turning cuts edge, the end face of these moulding product is carried out five equilibrium, commutator segment 2 behind the five equilibrium is corresponding in twos, its corresponding bisector is on same straight line, milling cutter is placed on carries out groove milling on the collinear bisector, the groove that is milled is insulation tank 1, after groove milling is finished, it is milled hook, the hook 3 that mills is positioned at the mid point of commutator segment 2 cambered surfaces, at last to its crotch, the commutator with cold-pressed end face product, whole production technology is promptly all finished.The cold extrusion commutator product of finishing by manufacture method of the present invention, not only saving working hour but also material saving, not can because of the commutator segment of correspondence not point-blank, symmetry and produce shortcomings such as spark, hot-tempered sound are big when causing motor commutation, the useful life of also having improved motor simultaneously, according to the commutator with cold-pressed end face product that theme of the present invention is produced, making for vast motor and bring positive result of use.
Claims (3)
1, a kind of manufacture method of commutator with cold-pressed end face, it is after the round copper wire cutting, carry out cold-extruded and be pressed into the commutator blank, after the cleaning with it injection-compression molding, after turning, groove milling, milling hook, last crotch forms, when it is characterized in that groove milling, end face is carried out five equilibrium, on symmetrical five equilibrium straight line, use a groove milling of milling cutter.
2, the manufacture method of a kind of commutator with cold-pressed end face as claimed in claim 1 is characterized in that described injection-compression molding process is to carry out extrusion modling filling up phenolic moulding powder in the cavity volume of blank, obtains the end commutator of moulding.
3, the manufacture method of a kind of commutator with cold-pressed end face as claimed in claim 2 is characterized in that described turning operation is the end commutator of moulding to be carried out inside and outside circle cut edge.
