Abstract
The invention discloses a kind of novel forming technologies of commutator segment, it draws row-punching press middle part-punching-to tear slot the following steps are included: squeezing, the present invention is directed to " rise piece " structure of starting motor of automobile commutator, play the role of improving copper material utilization rate, simultaneously, the difference of outer diameter up and down for being somebody's turn to do " rise piece " structure commutator is bigger, and the utilization rate of raising is more.
Description
Technical field
The present invention relates to motor parts technical fields, and in particular to a kind of novel forming work of commutator segment
Skill.
Background technique
Commutator is direct current generator, commutates as electric current on A.C. series motor, in order to allow motor persistently to turn
The component moved down, is commonly called as commutator, round, each touching being separately connected on rotor that commutator is that several contact chips surround
Head, two electrodes of outside connection are known as brush and contact, while only contacting two therein.After coil passes through electric current,
It can be rotated by attracting with repulsive force under the action of permanent magnet, when it goes to magnet balance, lead to line a little originally
Contact on more corresponding commutator is just separated with brush, two brushes be connected to meet generate motive force that group of coil it is corresponding
It on contact, ceaselessly repeats down in this way, direct current generator is just turned over, and commutator is mainly used on electric tool, commutation
The Key Performance Indicator of device refers to its hypervelocity performance, and the high commutator of hypervelocity performance can guarantee product quality, improve and produce
Product service life.Has high hypervelocity performance, product first will have high mechanical strength, i.e. commutator segment and commutator
Bond strength between ontology wants high.
In the prior art, since automobile starting motor commutator largely uses " rise piece " structure commutator, copper bar exists
There are mainly two types of structures in forming process: the first is a direct straight line copper bar, and " rise piece " finishes turning molding；Second
Kind be copper bar at the time of molding, the punching of rise piece redundance removes；But either vehicle falls redundance and still washes out redundance,
For commutator segment at molding aspect, the utilization rate of copper material all can be relatively low, and it is 3-4 times of practical materials that copper material, which feeds intake,.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the present invention provides a kind of commutator segment it is novel at
Type technique, by the principle of waste material at two panels commutator segment public one, to increase copper material utilization rate of the commutator segment in forming process.
Technical solution: in order to achieve the goal above, a kind of novel forming technology of commutator segment of the present invention,
It the following steps are included:
Step 1: copper material obtains copper bar by Warm Extrusion process and the row's of drawing process；
Step 2: being removed punching in the middle part of copper bar by way of punching press, and obtain 2 " 7 " word row's structures divides copper bar；
Step 3: the waste part for dividing copper bar of punching press " 7 " word row's structure；
Step 4: " 7 " word row is torn dividing at copper bar sheet for structure by mold, angle needed for forming commutator segment.
As present invention further optimization, in the step one, the shape of copper bar is diamond shape.
As present invention further optimization, in the step four, by hydraulic press and tearing groove mould will divide copper bar to tear
It opens.
As present invention further optimization, in the step four, the required angle torn be equally divided into carry out for 3 times by
Step is torn, and the effect for the angle torn is exactly in order to which the angle of commutator segment can form circumference after combining.
The utility model has the advantages that a kind of novel forming technology of commutator segment of the present invention, for starting motor of automobile
" rise piece " structure of commutator plays the role of improving copper material utilization rate, meanwhile, above and below " rise piece " the structure commutator
Outer diameter difference is bigger, and the utilization rate of raising is more.
Detailed description of the invention
Fig. 1 is process flow chart of the invention.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated.
As shown in Figure 1, a kind of novel forming technology of commutator segment, it the following steps are included:
Step 1: copper material obtains copper bar by Warm Extrusion process and the row's of drawing process, and the shape of copper bar is diamond shape；
Step 2: being removed punching in the middle part of copper bar by way of punching press, and obtain 2 " 7 " word row's structures divides copper bar；
Step 3: the waste part for dividing copper bar of punching press " 7 " word row's structure；
Step 4: by hydraulic press and tear groove mould by " 7 " word row dividing at copper bar sheet for structure tear, formed commutator segment
Required angle, the required angle torn are equally divided into 3 times and are gradually torn.
Start motor, rise piece outer diameter Φ 42, small outer diameter: Φ 29.8 the following is the comparative experiments before improving and after improving
Data
The technical concepts and features of above embodiment only to illustrate the invention, the purpose is to allow be familiar with the technical field
Technical staff cans understand the content of the present invention and implement it accordingly, and can not limited the scope of the invention with this.All
The equivalent changes or modifications made according to spirit of the invention, should be covered by the protection scope of the present invention.
