Description
Technical field
The invention belongs to Machining Technology field, be specifically related to a kind of semi-metallic lining preparation facilities and preparation technology.
Background technology
As everyone knows, automotive disc brake is by the friction material on friction plate under external force and produce frictional force between brake disc surface and implement to brake, and therefore friction material can produce wearing and tearing, after this wearing and tearing reach certain level, friction plate can be thinning, therefore want regularly to change friction plate, otherwise the formulation usefulness of automobile can be affected.But because automobile brake disc is collar plate shape, usually also friction plate is made into fan-shaped, fan-shaped external arc (radius is R) is more smaller than disc outer diameter, (radius is r) large than brake disc internal diameter to fan-shaped Inner arc, R is greater than r obviously, and brake disc is rotating in the middle of running car, according to linear velocity computing formula, increase gradually with the linear velocity of friction plate from Inner arc to external arc of brake disc, this will certainly cause the wearing and tearing of friction plate from Inner arc to external arc also to increase gradually, the uneven of this wearing and tearing also must impact vehicle brake efficacy.
Summary of the invention
Technical problem to be solved by this invention is for the uneven problem of friction disc wear, provides a kind of semi-metallic lining preparation facilities and preparation technology, makes the wearing and tearing trend of whole friction plate evenly.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
Semi-metallic lining preparation facilities of the present invention, comprise pedestal, described pedestal is fixedly connected with column, column is provided with quill, described sleeve is provided with wire support, described wire support is fixed with some circle wires, described wire support is provided with at least two binding posts, wire one end connects one of them binding post, the wire other end connects another binding post, the described wire that often encloses is provided with switch-dividing and resistance, and all wires connect a master switch, are provided with the workbench placing semi-metallic lining grinding tool below described wire support.
Described wire support is right-angled intersection support, is provided with line card below described right-angled intersection support.
Described resistance is adjustable resistance.
Described wire is circularly and evenly distributed.
Semimetal sheet preparation facilities of the present invention prepares the preparation technology of semimetal sheet, comprises the following steps:
(1) semi-metallic lining is by the material formulation of following parts by weight: resin 8 ~ 10, steel fibre 32 ~ 38, glass fibre 5 ~ 7, copper powder 4 ~ 5, reduced iron powder 4 ~ 6, synthetic rubber 2 ~ 4, graphite 5 ~ 7, molybdenum bisuphide 3 ~ 5, aluminium oxide 1 ~ 3, barium sulfate 12 ~ 15, diatomite 2 ~ 3, zinc oxide 2 ~ 3, alcohol 8 ~ 10;
(2) material preparing semi-metallic lining in step (1) to be mixed at normal temperatures and after stirring, form semisolid and to dissociate shape mixture, according to differentiated friction sheet specification, 350g ~ 700g mixture is put into corresponding plastic friction sheet grinding tool;
(3) friction plate grinding tool is placed on workbench, movable sleeve is regulated to make the induction coil in supporting construction be positioned at 2 ~ 5mm position above plastics grinding tool, open master switch and switch-dividing, according to different friction plate specification regulating resistance sizes, interior loop current is 0.5 ~ 2A, increase progressively often to enclose 0.1 ~ 0.3A from inside to outside, after 3 ~ 5s, close master switch;
(4) friction plate grinding tool is moved to baking oven, dries to solid-state, then change grinding tool and carry out hot-forming, after cooling, then carry out friction plate polish post processing.
Because each point of circuit size of current is from inside to outside in trapezoidal increase, the electromagnetic field intensity of each point of circuit generation also becomes gradient to increase, under the effect of electromagnetic induction, metallic fiber in mixture in friction plate grinding tool chamber is progressively separated out, its metallic fiber separate out density not only diametric(al) from inside to outside density increase gradually, and also become gradient to increase at thickness direction the closer to friction surface, because friction plate usual thickness wearing and tearing 3mm just needs to change, and friction plate gross thickness will at more than 10mm, therefore, by adjusting the size of each point of line current and induction coil wire and friction plate grinding tool upper surface distance size, the precipitation density of metallic fiber in mixture just can be made not only larger in diametric(al) density, this be distributed be beneficial to the closer to external diameter direction more wear-resisting, effectively can resist the wearing and tearing more caused because linear velocity increases close to outer radius and increase phenomenon, and be also conducive to more greatly improving its wearability the closer to rubbing surface density in through-thickness Density Distribution.Friction plate is less the closer to the another side metallic fiber density that rubbing surface is corresponding, because this face is directly connected with steel backing, only plays interconnective effect, and thus the minimizing of its metallic fiber also can not affect it and normally uses.
Beneficial effect of the present invention: the present invention utilizes electromagnetic induction principle, the distribution density of metallic fiber in semi-metallic lining is increased gradually from Inner arc to external arc, to improve the antiwear property from Inner arc to external arc surface gradually, make the wearing and tearing trend of whole friction plate evenly, whole preparation facilities structure is simple, easy to operate, preparation technology operates easy, practical.
