Description
Technical field
It the utility model is related to powder material compact technique field, and in particular to a kind of powder material pressure setting.
Background technology
Powder metallurgy friction material is using metal and its alloy as matrix, adds friction component and lubricant component, uses powder
Composite made of metallurgical method.Powder metallurgy friction material has enough intensity, suitable and stable coefficient of friction, work
The advantages that work is steady reliable, and wear-resisting and pollution is few, is one of widely used material in modern brake material family.It is existing
The powder metallurgical technique that generally uses of bullet train brake pad be to suppress the compound containing different component in die cavity
It is combined together into the effigurate briquet of tool, then by briquet with steel back by HTHP (sintering), steel back is in sintering
Preceding progress copper coating processing.As railroad train is to the trend of high speed development, the load that brake pad is subject to increases, and lock
The smelting with steel back can not be realized in pressure sintering process containing nonmetalloid, these nonmetalloids such as a large amount of graphite in piece
Gold combines, and is easily separated from the junction between brake lining friction material and steel back, causes great traffic safety hidden danger.In order to solve
Above-mentioned technical problem, Chinese patent CN201779183U discloses a kind of powder metallurgy brake pad with transition zone, by lock
Increase by one layer of 1-2mm transition zone between the friction material and steel back of piece, improve the bond strength of friction material and steel back.But
It is that prior art needs artificial cloth twice when producing brake lining in the form of transition zone, i.e., friction material first is put into mould
In tool, then transition zone is put into mould, greatly reduces production efficiency.
Although prior art discloses the pressure setting of some mechanizations, such as Chinese patent literature CN203919764U public affairs
A kind of disc brake pad pressure setting is opened, including support and the telescoping mechanism for being placed in frame bottom, pushing away at the top of telescoping mechanism
Bar is placed in compression chamber through the bottom plate of compression chamber, and compression chamber top middle portion is provided with charging aperture.By driving telescoping mechanism
Push rod moving up and down in compression chamber is suppressed the brake block in mould, and solution is manually taken caused by brake block
The problem of labor intensity height and poor safety performance, but because the compacting object brake block in the patent document is to clamp in advance
In a mold, it is not related to being separately added into and addition sequence problem for various materials.
And Chinese patent literature CN203542964U discloses a kind of brake block multi-cavity bilayer material injecting device, promotion is first passed through
Lower movement only logical plate and in place, makes the friction material in lower moulds fed template die chamber all be injected by own wt in mould cavity,
Again by mobile only logical plate in promotion and in place, the friction material in moulds fed template die chamber is made all to inject mould by own wt
Have in die cavity.Although being separately added into for two kinds of different materials, the structure of whole device can be completed in the patent document
It is more complicated, it is necessary to which upper movement stops the material hole on logical plate, the through hole in lower charging template, lower movement stop logical material on logical plate
Material hole and number, the shape of the die cavity on brake block press-moulding die on hole, base is identical with position, Cai Nengbao
Card friction material is smoothly injected in die cavity, and only after the friction material injection of lower floor, the friction material on upper strata could inject,
Flexibility is poor.
Utility model content
Therefore, the technical problems to be solved in the utility model is to overcome various powders material of the prior art injecting
Operation when in same die cavity is more complicated, higher to the required precision of device in itself, at the same injection order flexibility it is poor lack
Fall into, a kind of simple in construction so as to provide, various powders material can be implanted sequentially the powder material pressure setting in die cavity on demand.
In order to solve the above-mentioned technical problem, the utility model provides a kind of powder material pressure setting, including：
Support component, form at least one die cavity；
At least two feeding material components, it is movably disposed in the support component, at least two feeding material component exists

On bar 134, the core bar 135 is extended in the through hole through hole reserved on the insertion section 123.Such powder material
It will inject in the space before core bar 135 and die cavity 11, compressing and after ejecting, hole among one will be formed
Finished product.Whether core bar 135 can need middle pore-forming flexibly to install according to finished product.
Insertion section 123 is the low punch that intermediary form has cavity, and the upper punching to match with low punch is provided with pressing assembly 3
First 31, upper punch 31 and low punch act on simultaneously so that compacting is more uniform.
Powder metallurgy brake pad with transition zone includes steel back, transition zone and friction material, wherein transition zone and friction material
After material compacting forms briquet, then it is sintered together by HTHP with steel back, the compressing process of briquet is specific as follows：
Base 12 is fixed on work top first, top installation low punch.Then by two bars of ejecting mechanism 13
Part 133 is arranged in the first cavity 1221 of base 12, while in the through hole of low punch insertion ejecting mechanism 13, the top of the two
Flush, the certain space of distance between low punch and knock-pin 134.Magazine 21 mounted with feed bin 23 is placed on again
On the top plate 131 of ejecting mechanism 13, friction material and buffer layer material are injected separately into two feed bins 23.Finally by hydraulic cylinder
The push rod 22 with magazine 21, the knock-pin 134 of ejecting mechanism 13 and pressing assembly 3 are connected respectively.Drive the edge of ejecting mechanism 13
First cavity 1221 moves upwards, through hole top is formed die cavity 11, move distance with the friction material that will inject number
It is adjusted, can so reduces the movement travel of pressing assembly 3 as far as possible.Then driving push rod 22 promotes be loaded with friction forward
The opening that the magazine 21 of material moves to die cavity 11 starts material feeding, after shot reaches requirement, drives it to leave die cavity 11
Opening；Ejecting mechanism 13 is driven to be continued up along the first cavity 1221 again, transition zone of the move distance that will inject
The number of material is adjusted, and then drives another push rod 22 to promote the magazine 23 for being loaded with buffer layer material to move to mould forward
The opening material feeding of chamber 11, and drive it to leave the opening of die cavity 11 after shot reaches requirement.Hydraulic package band is driven again
Dynamic upper punch 31 moves towards the direction of low punch, now can continue to active force to knock-pin 134 by hydraulic cylinder, this
Sample upper punch 31 and low punch are suppressed the material in die cavity 11, after compressing, drive ejecting mechanism 134 again
Continue up, briquet is ejected into die cavity 11, carries out subsequent processing.
As alternative embodiment, feed bin 23 can also be connected with magazine 21 by connecting rod, the both ends point of connecting rod
It is not pivotally connected with feed bin 23 and magazine 21, ensures that magazine 21 can move freely between storing position and feeding position.
As alternative embodiment, die cavity 11 can be set on ejecting mechanism 13 it is multiple, can be with multigroup powder material
It is simultaneously compressing, improve operating efficiency.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
