Description

A kind of carbon brush manufacturing device
Technical field
The present invention relates to carbon brush manufacturing technology fields, and in particular to a kind of carbon brush manufacturing device.
Background technique
Carbon brush is also referred to as brush, is a kind of slide contact member being widely used in electrical equipment.The master of carbon brush is made Wanting material includes graphite, leaching rouge graphite, metal (cupric, silver) graphite.According to the characteristic that graphitic conductive is good and heat conductivity is good, Carbon brush is made by three of the above material, usually apply to motor or generator and other rotating mechanisms fixed part or Energy or signal are transmitted between person's rotating part.Therefore, the demand of carbon brush is very big, needs largely to produce.
There are two types of the manufactures of carbon brush, one is by mixing graphite powder according to a certain percentage with metal powder, so Carbon brush is solidified by the way that freezing plastic is added afterwards, since this kind of mode is solidified by freezing plastic, freezing plastic is easy under the high temperature conditions Thawing causes carbon brush working effect bad.Another way is to be pressed into carbon according to a certain percentage by graphite powder and metal powder Brush will appear metal powder and mix the working effect for unevenly causing conduction or transmitting signal with graphite powder during compacting It is bad.Traditional two kinds of manufactures are all that the graphite powder for being 99% by purity prepares carbon brush, still, in the process of preparation In bulky grain present in graphite powder is not removed, there are bulky grains will cause whole uneven of carbon brush in carbon brush, To influence the working effect of carbon brush.In carbon brush preparation process, there is also metal powders, and non-uniform situation is mixed with graphite powder, gold The mixing for belonging to powder and powdered graphite is uneven, influences the uniformity of carbon brush and influences the electric conductivity of carbon brush and transmit signal Ability.
Summary of the invention
The purpose of the present invention is to provide one kind to mix non-uniform carbon brush manufacturing device to solve carbon brush raw material.
In order to achieve the above objectives, the technical scheme is that a kind of carbon brush manufacturing device, including rack, motor, shaft And rotating cylinder, the motor side are fixedly installed with air blower, the rotating cylinder is located above motor and is installed in rack, rotating cylinder with Gantry rotation connection, rotating cylinder outer sheath are equipped with the sand cylinder connecting with drum rotation, and sand cylinder is fixed with positioned at sand cylinder and turns Mill ball between cylinder, sand cylinder are fixedly installed in rack, and the side wall of rotating cylinder is equipped with the centrifugal hole being connected to sand cylinder, rotating cylinder Bottom is fixed with hollow shaft, shaft is connected to rotating cylinder, and shaft is connected to motor, and air blower is equipped with and is connected to shaft Tracheae, rotating cylinder top are fixed with the material path being installed in rack and punching press case, and the material path is connected to rotating cylinder, the punching press case Interior vertical equipped with by the closed staking punch of punching press case, staking punch is connected with fixation and is satisfied with to provide kinetic energy in rack and for staking punch Power mechanism, punching press case side wall are equipped with the plup inlet being connected to material path;Punching press bottom portion is equipped with Die and mould plate, and Die and mould plate is equipped with Carbon brush mould for carbon brush sizing.
Technical principle of the invention: graphite powder and a certain proportion of metal powder are placed in rotating cylinder, start motor and drum Blower works, and motor drives shaft to be rotated, and shaft drives rotating cylinder to be rotated, and graphite powder and metal powder are in rotating cylinder Be subject to centrifugal forces and uniformly mixed, in graphite powder and metal powder biggish particle by centrifugal force act on, particle from It is detached from rotating cylinder and is entered in sand cylinder by centrifugal hole.Under the action of rotating cylinder and sand cylinder, bulky grain by rotating cylinder and The extruding of mill ball between sand cylinder is ground, and ground graphite powder and metal powder are collected in sand cylinder.Air blower Work simultaneously blast a large amount of gas to rotating cylinder, the gas blasted using air blower again by rotating cylinder graphite powder and metal powder it is equal Even mixing.Under the action of air blower, the mixed powder of a large amount of graphite powder and metal powder is blown in material path, and mixed powder is in material path It is interior to be blown at punching press case by air blower, entered in punching press case by the plup inlet of punching press case.Punching press case collects mixed powder and reaches one Fixed amount starts power mechanism as staking punch punching press straight down and provides kinetic energy, staking punch in punching press case to stone mixed powder into Row compacting.Staking punch moves downward, the extruding in punching press case by staking punch, the gas in punching press case be discharged from plup inlet and Only remaining mixture.Staking punch squeezes the mixed powder in punching press case to Die and mould plate, and mixed powder is on Die and mould plate, because by punching press The punching press of head can form carbon brush in carbon brush mould, complete carbon brush and manufacture work.
Beneficial effects of the present invention: (1) blasting the gas in rotating cylinder using air blower can be hit in rotating cylinder inner sidewall, To form turbulent flow, turbulent flow mixes the graphite powder for manufacturing carbon brush and metal powder uniformly, to improve the quality of carbon brush.
(2) under the influence of centrifugal force, graphite powder and metal powder bulky grain are screened into grinding case for graphite powder and metal powder Inside ground.The bulky grain in graphite powder and metal powder is reduced, so that carbon brush surface is more smooth, improves carbon brush to reach Quality.
(3) rotating cylinder rotation can using centrifugal force to graphite powder and metal powder progress the first uniform stirring mixing, air blower to Rotating cylinder blasts gas and forms turbulent flow, carries out second of uniformly mixing to graphite powder and metal powder.Repeatedly mixing is manufactured to guarantee Carbon brush graphite and metal are uniform, guarantee the quality of carbon brush.
On the above base case:
Preferred embodiment one: opposite arc bump keeps shaft middle part formation one negative there are two setting in the middle part of in the shaft Mouth is pressed, the sand cylinder is equipped with the conduit being connected to negative pressure mouth.When air blower dries to rotating cylinder and passes through shaft, the wind of flowing exists Negative pressure is formed at negative pressure mouth, it, will be in sand cylinder by the graphite powder of rotating cylinder and sand cylinder grinding by conduit under the action of negative pressure It is drawn onto shaft with metal powder, the wind blown by air blower takes in rotating cylinder.
Preferred embodiment two: the nitrogen box being fixed on the air blower and rack is connected to and air blower to rotating cylinder is passed through nitrogen Gas.Because graphite powder and metal powder can be dispelled by air blower in rotating cylinder, it is full of in entire rotating cylinder and mutual frictional heat generation, It is easy to cause powder explosion.A large amount of nitrogen is passed through to the storage space that air is reduced in rotating cylinder, oxygen contains in reduction air Amount, to avoid powder explosion.
Preferred embodiment three: being equipped with exhaust fan on the staking punch, exhaust fan is equipped with the exhaust column being connected to punching press case.It is logical It crosses exhaust fan to take the air in punching press case away, punching press box-shaped can be made at negative pressure, to accelerate to graphite powder and metal powder Sucking, improve working efficiency.
Preferred embodiment four: the carbon brush mould at least two.It, can when staking punch carries out punching press to graphite powder and metal powder Carbon brush is formed in multiple carbon brush moulds to improve working efficiency.
