Abstract
The utility model discloses a powder metallurgy friction disc, including powder metallurgical material frictional layer and backplate, be equipped with a plurality of archs on the surface of backplate, the powder metallurgical material frictional layer passes through protruding with backplate shaping suppression, a sintering body structure. The utility model discloses a powder metallurgy friction disc through setting up protruding structure, can strengthen the shear strength between friction material and the backplate, can effectively cushion brake pressure, alleviates the friction disc and phenomenons such as piece and mill partially because of what abominable operating mode caused, have simple structure, low cost, pressed compact place the degree of difficulty little, need not to design in addition advantages such as frock, work load reduce greatly.
Description
Technical field
The utility model belongs to friction plate technical field, particularly relates to a kind of powder metallurgy friction plate.
Background technique
The friction plate of prior art is by friction metallurgical material being put into cold stamping die compacting, obtaining pressed compact, then be fixed on backboard by pressed compact, and pressure sintering in hydrogen sintering furnace, namely obtain friction plate.Fig. 1, Fig. 2 are certain bullet train friction plate schematic diagram existing, be sintered in after friction material is compressing on backboard, the device that periphery is sheared without other restrictions, bonding only by powdered metallurgical material and backboard of bonding strength, under extreme working position, friction material easily falls block, and cause the phenomenons such as eccentric wear, be unfavorable for the product work life-span, bring very large hidden danger to Product Safety.Meanwhile, sinter together owing to being placed on backboard after pressed compact compacting, periphery can arbitrarily move freely again, and makes pressed compact place difficulty comparatively greatly, separately need design frock, increase workload and cost.
Model utility content
Technical problem to be solved in the utility model is, overcome the deficiency and defect mentioned in above background technique, provide that a kind of structure is simple, with low cost, pressed compact place difficulty little, without the need to designing frock in addition, powder metallurgy friction plate that workload reduces greatly.
For solving the problems of the technologies described above, the technological scheme that the utility model proposes is:
A kind of powder metallurgy friction plate, comprise powdered metallurgical material friction layer and backboard, a surface of described backboard is provided with multiple projection, and described powdered metallurgical material friction layer is suppressed by described projection and described backboard, be sintered into one structure.
Further, the angle between described projection and described backboard is 30 ° ~ 90 °.
Further, the height of described projection is 0.5 ~ 5mm.
Further, the profile of described backboard is equilateral triangle or regular polygon or circle, and its size is less than the boundary dimension of powdered metallurgical material friction layer, and described backboard embeds described powdered metallurgical material friction layer.
Further, described backboard and described projection are punching press integrated formed structure.
Further, the outside of described backboard forms multiple groove, and described projection takes shape on the side of described groove.
Further, described backboard is also provided with more than one aperture be filled with for powdered metallurgical material.
Compared with prior art, the utility model has the advantage of:
Powder metallurgy friction plate of the present utility model, by arranging multiple projection on backboard, powdered metallurgical material friction layer is suppressed by this projection and backboard, be sintered into one structure, multiple projection can strengthen the shearing strength between friction material and backboard, can effective buffer-braking pressure, what alleviate that friction plate causes because of bad working environments the phenomenon such as block and eccentric wear.The size of backboard is less than powdered metallurgical material friction layer, and backboard embeds powdered metallurgical material friction layer, puts the problem of location difficulty when can solve existing structure sintering.And backboard is provided with aperture, during sintering, powdered metallurgical material can embed in aperture, make powdered metallurgical material better and backboard combine closely.The utility model has that structure is simple, with low cost, pressed compact place difficulty little, without the need to designing the advantages such as frock, workload reduce greatly in addition.

Embodiment
For the ease of understanding the utility model, hereafter will do to describe more comprehensively, meticulously to the utility model in conjunction with Figure of description and preferred embodiment, but protection domain of the present utility model is not limited to following specific embodiment.
It should be noted that, when a certain element is described on " be fixed on, be fixed in, be connected to or be communicated in " another element, it can be directly fixing, affixed, connect or be communicated with on another element, also can be by other intermediate connectors indirectly fixing, affixed, connection or connection on another element.
Unless otherwise defined, hereinafter used all technical terms are identical with the implication that those skilled in the art understand usually.The object of technical term used herein just in order to describe specific embodiment is not be intended to limit protection domain of the present utility model.
Embodiment 1:
As shown in Fig. 3, Fig. 4, Fig. 5, a kind of powder metallurgy friction plate of the present utility model, comprise powdered metallurgical material friction layer 1 and backboard 2, a surface of backboard 2 is provided with multiple protruding 3, powdered metallurgical material friction layer 1 on the surface of backboard 2, forms integrative-structure by multiple protruding 3 compactings, sinter molding.Powdered metallurgical material friction layer is suppressed by this projection and backboard, be sintered into one structure, multiple projection can strengthen the shearing strength between friction material and backboard, can effective buffer-braking pressure, what alleviate that friction plate causes because of bad working environments the phenomenon such as block and eccentric wear.
In the present embodiment, backboard 2 is equilateral triangle, and three angles of backboard 2 all form a groove, protruding 3 take shape on the side of groove, itself and backboard 2 are punching press integrated formed structure, and protruding 3 is highly 0.5 ~ 5mm, and the angle between protruding 3 and backboard 2 is 30 ° ~ 90 °.The size of backboard 2 is less than the boundary dimension of powdered metallurgical material friction layer 1, and backboard 2 embeds powdered metallurgical material friction layer 1, can strengthen the shearing strength between friction material and backboard, and puts the problem of location difficulty when can solve existing structure sintering.In the present embodiment, backboard 2 is also provided with an aperture 4 be filled with for powdered metallurgical material, powdered metallurgical material when powdered metallurgical material friction layer 1 sinters, can be made to be filled with in aperture 4, make powdered metallurgical material better and backboard combine closely.In other embodiments, also can uniform multiple aperture 4 on backboard 2.
