Abstract
The present invention relates to solve the mold of the commutator of extra meat and the processing commutator at crotch.Round and smooth structure including commutator ontology (1) and the crotch (2) being arranged on commutator ontology (1), on the inside of the crotch (2) at hook line for indent.Mold includes formed punch (3) and directional commutator cavity plate (4), the cavity plate (4) has following structure type: two interdigital (41) in fork configuration including being fastened on commutator ontology (1) and crotch (2) contact portion, and the positioning mobile jib (42) to form a fixed connection with two interdigital (41).The difficulties that the drawbacks of that the present invention overcomes the amounts of labour used for perplexing commutator industry due to commutator segment crotch technology for a long time is big, abrasion enameled wire, quality are not easy to guarantee, have the characteristics that protrusion, significant technological progress and beneficial effect.
Description
Technical field
The present invention relates to the mold of the commutator of extra meat and the processing commutator at crotch is solved, it is applied to motor skill
Art field.
Background technique
Currently, processing procedure process (including crotch) post of commutator (also known as commutator) industry of motor be commutator most
The link of crucial importance that finished product generates, in the structure with orderly cylinder packings, there is the differentiations of upper and lower directionality
And the insulation sexual intercourse between copper body and copper body.In motor, enameled wire is determined by hook at the commutator segment crotch of Hooked reverser
It is wrapped on rotor, the voltage for making motor generate rectification runs well.The commutator segment of well known Hooked reverser is in crotch
The two sides of preceding commutator segment hook portion be it is linear, it is unsmooth at commutator segment crotch crotch after molding and there are fold, extra meat
With burr etc., then easily make that enameled wire is damaged during hook is determined, incised wound, the naked copper of enameled wire is caused to aoxidize and affect motor
Quality of cummutation, and shorten motor service life.Therefore, commutator requires smooth, impulse- free robustness at commutator segment crotch, in manufacture
The techniques such as burring, polishing should also be increased.These are undoubtedly also that the amount of labour used is big, benefit is not high, quality is not easy to protect in industry process
Card, post management cost are difficult to the difficulties compressed.
Summary of the invention
The present invention during, and it is an object of the present invention to provide one kind makes enameled wire, hook is determined at commutator segment crotch in view of the foregoing drawbacks not
The mold of meeting is damaged, hurts Hooked reverser and the processing commutator.
Thus the technical solution adopted by the present invention is that: the present invention include commutator ontology (1) and be arranged in commutator ontology
(1) crotch (2) on is the round and smooth structure of indent at hook line on the inside of the crotch (2).
A kind of mold for processing the commutator, the cavity plate (4) including formed punch (3) and directional commutator, the cavity plate (4)
Have following structure type: including be fastened on commutator ontology (1) and crotch (2) contact portion in the two interdigital of fork configuration
(41), the positioning mobile jib (42) and with two interdigital (41) to form a fixed connection.
Two interdigital (41) angle is 120 degree, the transition position rounding off of two interdigital (41).
Two interdigital (41) are symmetrical arranged about the positioning mobile jib (42).
The invention has the advantages that the present invention overcomes perplex commutator industry due to commutator segment crotch technology for a long time
The amount of labour used it is big, benefit is not high, quality is not easy to guarantee, cost is difficult to the difficulties compressed, have the characteristics that prominent, significantly
Technological progress and beneficial effect.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the mold structure diagram for processing commutator of the present invention.
Fig. 3 is the structural schematic diagram of cavity plate of the present invention.
1 it is commutator ontology in figure, 2 be crotch, 3 be formed punch, 4 is cavity plate；
41 for it is interdigital, 42 be positioning mobile jib.
Specific embodiment
The present invention includes commutator ontology 1 and the crotch 2 that is arranged on commutator ontology 1, at the 2 inside hook line of crotch
For the round and smooth structure of indent.
A kind of mold for processing the commutator, the cavity plate 4 including formed punch 3 and directional commutator, the cavity plate 4 have with
Flowering structure form: including be fastened on 2 contact portion of commutator ontology 1 and crotch in the two interdigital 41 of fork configuration, and with two
The interdigital 41 positioning mobile jibs 42 to form a fixed connection.
Two interdigital 41 angle is 120 degree, two interdigital 41 transition position rounding off.
Described two interdigital 41 are symmetrical arranged about the positioning mobile jib 42.
The process of commutator of the invention are as follows: the present invention is fastened on 1 He of commutator ontology for the two of cavity plate 4 interdigital 41
The contact portion of crotch 2, two interdigital 41 are symmetrically arranged in the two sides of contact portion, then realize crotch 2 by positioning mobile jib 42
Positioning, then the bending of crotch 2 is realized in the downward punching press of formed punch 3.
Claims (4)
