Description
Technical field
The utility model relates to carbon brush production fields, and in particular to a kind of carbon brush press device.
Background technique
Carbon brush is also brush, as a kind of slide contact member, is widely used in many electrical equipments.Carbon brush
Material mainly has graphite, leaching rouge graphite and metal (cupric, silver) graphite etc..Carbon brush is motor, generator or other whirlers
The device of energy or signal is transmitted between the fixed part and rotating part of tool, carbon brush can be suppressed using powdered graphite,
External form is usually square, is stuck on metallic support, and there is spring handle in the inside, and it is pressed in shaft, will be electric when motor rotates
Coil can be conveyed to by commutator.
When producing carbon brush, generally requires for powdered graphite to be added in mold and suppress, but powdered graphite granularity is small,
Conglomeration is easy when being under pressure in fill process, the raw material of conglomeration can not cause after entering in grinding tool full of entire mold inner-cavity
The carbon brush specification finally suppressed is smaller than standard component, and this carbon brush is substandard products, so needing to make in charging the raw material of conglomeration
Dispersion, to reduce defect rate.
Utility model content
The purpose of this utility model is to provide a kind of powder compacting pushers that the powdered graphite for making conglomeration disperses.
To achieve the above purpose, the technical solution of the present invention is: powder compacting pushing structure, including rack, into
Expect mechanism and rabbling mechanism, feeding mechanism include two closing springs, can along housing slide feed block, be each attached in rack
Rack gear and magnet, feed block be equipped with downward opening feed cavity；Feed block is equipped with feed inlet, is slidably connected in feed block
There are the first sealing plate and the second sealing plate that can close off feed cavity opening and feed inlet, two closing spring one ends are fixed on charging
On block, the other end is separately fixed on the first sealing plate and the second sealing plate, adsorbable second sealing plate of magnet, and makes the second door open structure
Discharge port；Rack is equipped with sliding slot and can be fixed with and can slide along the chute on the first sealing plate with the discharge port of feed cavity register
Dynamic sliding block；Rabbling mechanism includes the shaft being located in feed cavity, the gear and multiple stirring blades that are each attached in shaft, is turned
Axis and stir chamber are rotatablely connected, wheel and rack engagement.
The principle of this programme are as follows:
When initial, the first sealing plate closes the opening of feed cavity, work of second sealing plate in magnet under the action of closing spring
With lower opening feed inlet.When feed block being pushed to slide along rack to discharge port, after feed block and magnet distance increase, the second envelope
Plate closes feed inlet under closing spring effect.Since wheel and rack engages, in feed block sliding process, gear rotation,
Shaft rotation is driven, stirring blade is stirred the raw material in feed block, avoids raw material conglomeration.In feed block sliding process
In, sliding block is slided along sliding slot, when sliding block slides into sliding slot end, blocking of the sliding block by sliding slot, and fixed with sliding block the
One sealing plate can not continue to slide with feed block, and feed cavity opening is opened.Feed block is moved to the opening and discharge port of feed cavity
At alignment, the raw material in feed cavity falls into discharge port from opening, from the mold that discharge port falls into compacting carbon brush.Feed block is opposite
When rack reverse movement, the first sealing plate closes the opening of feed cavity under closing spring effect, and leans near magnet in feed block
When, magnet adsorbs the second sealing plate, and the second door open structure feed inlet completes primary charging.
This programme has the beneficial effect that
(1) before suppressing carbon brush, first make raw material full of feed cavity, then the raw material in feed cavity is added from discharge port again
Mold can so guarantee that the amount for the raw material being added in mold every time is all equal, and the carbon brush specification suppressed is identical.
(2) when mobile feed block, wheel and rack engagement, gear can be rotated, and shaft rotates with it, stirring blade pair
Raw material in feed cavity is stirred, and avoids raw material conglomeration, so that the raw material for avoiding enter into mold can not be full of in entire mold
Chamber suppresses the substandard products of part under gauge.
(3) two are closed the opening and feed inlet that springs can make the first sealing plate and the second sealing plate close off feed cavity,
When avoiding feed block relative to housing slide, the raw material in feed cavity is revealed between feed block and rack and stirring blade
When stirring, raw material is revealed from feed inlet, further avoids the material quantity entered in mold deficiency, produces specification less than standard component
Substandard products.
(4) when feed block leans near magnet, magnet can adsorb the second sealing plate, make the second door open structure feed inlet, can save
The time for slightly opening feed inlet, improve powder feeding efficiency.
Preferred embodiment one, as the further improvement to base case, stirring blade outer rim thickness is less than interior thickness.It stirs
It mixes in blade rotation process, raw material is moved along the surface of stirring blade, and stirring blade surface is arc-shaped at this time, can extend original
Expect the travel relative to stirring blade, keeps mixing effect more preferable.
Preferred embodiment two, as the further improvement to preferred embodiment one, multiple stirring blades in shaft are in difference
Highly.Stirring blade is sequentially arranged in shaft, is stirred to the raw material of feed cavity everywhere, is further increased mixing effect.
Preferred embodiment three, as the further improvement to preferred embodiment two, rack is equipped with reset spring, reset spring two
End is separately fixed in rack and feed block.After raw material in feed cavity is dropped out from discharge port, reset spring can make feed block
It resets, reduces the workload of worker.
Preferred embodiment four is fixed with limit plate as the further improvement to preferred embodiment three in rack, limit plate is located at
Above feed block.Limit plate can avoid feed block along the vertical direction relative to machine frame movement by feed block pressure on the rack, from
And sliding block is avoided to deviate from from sliding slot, guarantee that feed block can be slided along sliding slot, and can finally be aligned with discharge port.
Preferred embodiment five is fixed with locating piece as the further improvement to preferred embodiment four in rack, feed block and fixed
When position block offsets, feed block opening is connected to discharge port.When feed block and locating piece offset, feed cavity opening connects with discharge port
Logical, the raw material in feed cavity is fallen into discharge port.It only needs that feed block and locating piece is made to offset when charging, does not need artificial
The opening for judging feed cavity whether be connected to discharge port, avoided while reducing the workload of worker artificially judge generate mistake
Difference.
