Description
Technical field
The present invention relates to body-building apparatus field, relate to particularly a kind of magnetic conduction counterweight ring, magnetic control wheel and preparation method thereof.
Background technology
The magnetic control wheel of magnetic bike is the driven pulley on exercycle, and it has makes to trample the function that keeps inertia and great resistance exercise.It is mainly to provide resistance by magnetic force and electromagnetic induction for exercycle.According to the difference of magnet installation position, magnetic control wheel can be divided into outer magnetic control wheel, interior magnetic control wheel, side magnetic control wheel etc.
As shown in Figure 1, existing magnetic control wheel main body is mainly to be made by pig iron casting, and this kind of wheel body need to first be carried out sandbox, then by melt after casting of metals in sandbox, after shake out again, repair, the operations such as polishing.So not only shaping speed is slow, and it is large and cause waste of human resource to consume the energy, will be higher thereby the blank processing cost after casting is corresponding, the most important thing is, and production process can produce waste residue, waste gas and dust and contaminated environment a large amount of energy that consumes.
Summary of the invention
The object of the present invention is to provide a kind of magnetic conduction counterweight ring, magnetic control wheel and preparation method thereof, to solve the above-mentioned problems in the prior art.
Technical scheme provided by the invention is as follows:
A kind of magnetic conduction counterweight ring, is characterized in that, its raw material comprises by weight: 30-80 order iron powder, the graphite powder of the manganese sulfide of 3-8% iron powder weight, the sodium metasilicate of 3-8% iron powder weight and 6-12% iron powder weight.
The preparation method of aforesaid a kind of magnetic conduction counterweight ring, comprises the steps:
1), raw material is stirred;
2), hydraulic press is pressed into iron powder ring, adjust within the scope of 3000-6000 MPa according to iron hoop sectional area;
3), iron powder ring puts into electric furnace, electric furnace first adopts the heating of 400-800 degree, time 5-15 minute; Rear employing 1000-1200 degree heating, time 5-15 minute;
4) 300-600 ton hydraulic press secondary is compressing.Pressure is still adjusted within the scope of 3000-6000 MPa according to iron hoop sectional area.
A preparation method for magnetic control wheel main body, comprises the steps:
1) prepare magnetic conduction counterweight ring according to aforesaid method;
2) prepare round iron plate;
3) by round iron plate interlocking to magnetic conduction counterweight ring.
The present invention solves the problems referred to above that exist in existing magnetic control wheel main body, a kind of magnetic conduction counterweight ring is disclosed, this ring uses 30-80 order iron powder to add 3-8% manganese sulfide and 3-8% sodium metasilicate and 8% graphite powder to stir, through oil pressure extrusion modling, through flash baking, sintering, then the technique of hydrostatic profile, just can directly become qualified products.
Beneficial effect of the present invention is as follows:
1,30-80 object iron powder is mainly leftover pieces or the scrap iron slag of hardware, and through flour mill reprocessing, then magnetic separation screening obtains the iron powder of certain specification.Play like this twice laid, easily obtain, thereby reduce the cost, reduce the waste of the energy.
2, manganese sulfide and sodium metasilicate are all common raw material, also very easily obtain, and do not produce pollution.
3, sodium metasilicate (Na
2siO
3) be mainly to play adhesive effect, in the part that the repressed sintering of manganese sulfide (MnS) is made, manganese sulfide is mainly distributed near iron particle sintering neck or in iron inter-granular porosity, can obviously make up the additional percussion of hole.Increase the workpiece strength of cutting following process, also there is the greasy property that improves metal surface, can improve the fineness on processing metal surface, play the effect of kollag.Add sulfuration manganese powder, substantially do not affect raw-material other physical property and dimensional contraction and change.Graphite in composition is mainly in order to increase certain phosphorus content in sintering iron hoop process, thereby the hardness of iron hoop is increased.
4,, in heating up, CO is emitted in the oxygen molecule reaction in graphite powder and iron powder, prevents that iron powder is oxidized; Manganese sulfide plays the effect that reduces machined intensity in iron powder.
5, iron powder adds manganese sulfide, and sodium metasilicate and graphite powder etc. stirs, and is pressed into iron powder ring through 300 tons of hydraulic presses, and then electric furnace leading portion adopts 400-800 degree, and object is dried moisture fast, and back segment adopts 1100 degree, object Fast Heating.At this moment the inner semi liquid state that forms of iron powder ring, ferrous powder granules is bonded together naturally, and then compressing through 300-600 ton oil pressure secondary.Naturally cooling after coming out of the stove.Such product deformation is little, then passes through fine finishining, can use.And the tissue density of the part comparison mo(u)lded piece of producing is like this good.And because parts size precision is better, reduce machining workload, improved product percent of pass.
6, when the present invention has both made magnetic control wheel move, can produce enough resistances in magnetic field, again without the shaking out of background technology, repair, the operations such as polishing, have reduced production cost and environmental pollution.
