Abstract
The utility model discloses packet carbon commutator copper sheets, it is characterized by: being composed of copper piece and carbon part, carbon part has the appearance profile of copper segment, the copper piece is fixedly linked with carbon part, copper piece is from top to bottom through the centre of the carbon part, the upper end of copper piece exposes to carbon part, the upper end of copper piece forms the bonding wire crotch of commutator after being bent, the centre of copper piece is equipped with upper and lower punching press fenestra, copper piece blanking in upper punching press fenestra forms the upper fixed feet of copper segment in 90 degree of upward bendings, one end of upper fixed feet connects logical copper piece, the other end exposes to the medial surface of the carbon part；Copper piece blanking in lower punching press fenestra forms the lower fixed feet of copper segment in 90 degree of downward bendings, and one end of lower fixed feet connects logical copper piece, and the other end exposes to the medial surface of the carbon part.The utility model solves the problems, such as that the commutator segment of carbon commutator needs two sections of welding, guarantees commutator segment integral strength and energy conservation and environmental protection.
Description
Technical field
The utility model relates to a kind of commutators, and in particular to a kind of commutation copper sheet of carbon commutator.
Background technique
Commutator is mainly used on various motors, the motor of fuel pump, due to using under fuel oil environment, and in fuel oil
The surface of the copper commutator segment of commutator can inevitably be made added with alcohols materials, these alcohols materials such as some ethyl alcohol
At corrosion, so seriously affecting the service life of fuel oil pump motor.Currently, carbon commutator is mainly used in flat commutator, put down
Face carbon commutator, carbon plate, which will be brazed, to be fixed on the commutation copper sheet with bonding wire crotch, since contact area is big, so can protect
Bonding strength is demonstrate,proved, but for the Hooked reverser for carrying out Cylindrical Surfaces Contact with carbon brush for electric machine, the sectional dimension of commutator segment is small,
Carbon plate is directly the lower section of commutator segment, and so, the contact area between carbon plate and welding crotch can be smaller, it is difficult to guarantee to connect
Intensity is connect, so carbon commutator is rarely applied to the Hooked reverser of periphery, unless carrying out complicated design.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of commutator segments for solving carbon commutator to need
The problem of wanting two sections of welding guarantees commutator segment integral strength and energy-saving and environment-friendly packet carbon commutator copper sheet.
The utility model adopts the following technical scheme that complete:
Packet carbon commutator copper sheet, it is characterised in that: be composed of copper piece and carbon part, carbon part has the outer of copper segment
Shape profile, the copper piece are fixedly linked with carbon part, and for copper piece from top to bottom through the centre of the carbon part, the upper end of copper piece is exposed
In carbon part, the upper end of copper piece forms the bonding wire crotch of commutator after being bent, and the centre of copper piece is equipped with upper and lower punching press fenestra, on
Copper piece blanking in punching press fenestra forms the upper fixed feet of copper segment in 90 degree of upward bendings, and one end of upper fixed feet connects
Copper piece is connected, the other end exposes to the medial surface of the carbon part；Copper piece blanking in lower punching press fenestra is in 90 degree of downward bendings
The lower fixed feet of copper segment is formed, one end of lower fixed feet connects logical copper piece, and the other end exposes to the inside of the carbon part
Face.
The carbon commutator copper sheet of above-mentioned technical proposal, is composed of copper piece and carbon part, and carbon part has copper segment
The copper piece of bonding wire crotch is arranged from top to bottom through the centre of the carbon part in appearance profile, and being not required to welding can be realized copper piece
Being fixedly linked between carbon part, and then guarantee the integral strength of carbon commutator copper sheet and reach energy-saving and environment-friendly effect；Simultaneously
Copper piece forms securely knot when commutator is formed by the fixed feet up and down of its blanking punched formation between the matrix of commutator
It closes, guarantees the mechanical performance of carbon commutator.
It is arranged preferably, the fixed feet up and down is symmetrical above and below and there is same shape.
Preferably, the upper end that the copper piece exposes to carbon part has lesser width.Above-mentioned design can make bonding wire crotch
It is easier to form, while saving material.
Detailed description of the invention
Fig. 1 is the shape assumption diagram of the utility model,
Fig. 2 is the overlook direction figure of Fig. 1,
Fig. 3 is the axial sectional view of copper piece in Fig. 1,
Fig. 4 is the right view direction figure of Fig. 3.
Specific embodiment
As shown, the packet carbon commutator copper sheet of the utility model, is composed of, carbon part 1 has copper piece 2 and carbon part 1
The appearance profile of copper segment, carbon part 1 use graphite fluoride composite material, and the copper piece 2 is fixedly linked with carbon part 1, can lead to
It crosses carbon part 1 and is implanted into copper piece 2 in compression molding；Copper piece 2 is from top to bottom through the centre of the carbon part 1, outside the upper end of copper piece 2
It is exposed to carbon part 1, the upper end that copper piece 2 exposes to carbon part 1 forms commutation after there is lesser width, the upper end of copper piece 2 to be bent
The bonding wire crotch 3 of device, the centre of copper piece 2 are equipped with upper and lower punching press fenestra 6 and 7, and the copper piece blanking in upper punching press fenestra 6 is in upward
90 degree of bendings form the upper fixed feet 4 of copper segment, one end of upper fixed feet 4 connects logical copper piece 2, and the other end exposes to institute
State the medial surface of carbon part 1；Copper piece blanking in lower punching press fenestra 7 forms the lower fixation of copper segment in 90 degree of downward bendings
Foot 5, one end of lower fixed feet 5 connect logical copper piece 2, and the other end exposes to the medial surface of the carbon part 1, the upper and lower fixed feet 4
With 5 settings symmetrical above and below and with same shape.
