Description
Technical field
The utility model belongs to powder metallurgy die field, is powder metallurgy vibration shaping mould specifically.
Background technology
Metal dust is loaded steel mold cavity by die forming, powder is pressurizeed by stamping is allowed to shape.
Powder of the mold process in die cavity can produce so-called " arch due to intergranular friction and mechanical engagement effect
Bridge " phenomenon, forms many holes not of uniform size.During pressurization, the volume of body of powder is compressed, and its process is general relative with pressed compact
Density-pressing pressure curve is represented (Fig. 1).Relatively move and redistribute in incipient stage powder particle, hole is filled, from
And green density is sharply increased, reach maximum loading density；At this moment powder particle has been pressed tightly against each other, therefore when pressing pressure increases
When big, green density is almost unchanged, and curve presents flat.Increase pressing pressure is continued thereafter with, powder particle will occur elastic and plastic properties
Deformation or brittle fracture, make pressed compact further be densified.Due between the metallic atom on intergranular mechanical engagement and contact surface
Gravitation, body of powder after compacting turns into the pressed compact with some strength.The compacting of relevant powder is theoretical, from fertile gram of nineteen twenty-three
(E.E.Walker) argument for announcing him starts, and has had a tens of kinds of theoretical and empirical equations, wherein A Ji (L.F.Athy,
1930), the formula of Bali Shen (Μ Ю Б а л ь ш и н, 1938), river north public affairs husband (1963) et al. has certain Practical significance；
Even so, these theories are so far still in the exploratory stage.Pressing pressure is distributed in mold process with green density and suppresses pressure
Power is mainly consumed in following two parts：1. the change of the frictional force (referred to as internal friction) and powder particle between powder particle is overcome
Shape drag；2. powder particle is overcome to the frictional force (referred to as external friction power) of die wall.Due to the presence of external friction power, die forming
Green density distribution be actually it is uneven.It is for example during unidirectional compacting, higher from the partial density applied close to die punch,
Partial density farther out is relatively low.In two-way compacting (really two combinations of unidirectional compacting), pressed compact is along pressure parallel direction
Two ends density it is higher, centre is relatively low.Lubricant is added in powder or is applied on die wall and can be improved green density not
Uniformity.
The pressing process of prior powder metallurgy, powder metallurgy plastic fluidity is poor, and in compacting, simple leveling is suppressed
The finished product rate come is low, of low quality, and the mold releasability of existing powder metallurgy is cumbersome.
