In order to solve described problem, the inventor etc. conscientiously study repeatedly, the final discovery, melts is flowed out in the fused mass flowing nozzle used in the device of the small spherical particle of back formation, the stream internal surface of melts is made as the regulation shape that diminishes towards the smelt flow outlet, can improve the intensity of nozzle thus, also be easy to processing, and the situation that melts soak into to rise can take place hardly, can high precision and form small spherical particles such as melt drop stably in a large number, thus the present invention finished.
More specifically, the invention provides:
(1) a kind of fused mass flowing nozzle, it is formed with the stream of melts in inside, when being made as flowing path section with the stream shape that the vertical cross section of smelt flow outgoing direction is presented, and when the area of this flowing path section is made as flow path cross sectional area, the stream shape of described melts comprises at least: first internal surface, and it has the first flow path cross sectional area a1 of outflow side; Second internal surface, it links to each other with described first internal surface, and its sectional area changes to the second flow path cross sectional area a2 from the described first flow path cross sectional area a1; And the 3rd internal surface, it links to each other with described second internal surface, and has the described second flow path cross sectional area a2, and the relation of described first flow path cross sectional area a1 and the described second flow path cross sectional area a2 satisfies a1＜a2.
The stream shape of fused mass flowing nozzle of the present invention is: flow path cross sectional area towards contracted downstream, and has the part of flow path cross sectional area less than the inflow side from the part with regulation flow path cross sectional area of inflow side, and this part is connected to spout.
According to described form, even when reducing the area of spout, the upstream portion of spout still has bigger flow path cross sectional area, so can obtain to have high-intensity fused mass flowing nozzle.
And in the manufacturing process of fused mass flowing nozzle, when the drill bit that uses minor diameter was left spout, in most cases the length of the drill bit of this kind minor diameter was not enough.Be difficult to utilize this working method to form and have the long stream of small flow path area, but according to form of the present invention, because need not form the long stream with small flow path area, so can easily make fused mass flowing nozzle.
In addition, fused mass flowing nozzle is to be made by the material of costlinesses such as precious metal mostly.Therefore, consider the problem of cost, the wall thickness of fused mass flowing nozzle is restricted, and the profile of final fused mass flowing nozzle can be subjected to the considerable influence of stream shape.According to the stream shape of fused mass flowing nozzle of the present invention,, also can easily make the external surface shape of fused mass flowing nozzle become the shape that melts is difficult to soak into rising even have described restriction and influence.
In described structure, first internal surface has the peristome that melts is flowed out with the join opposition side of a side of second internal surface, and peristome links to each other with end face portion, and this end face portion links to each other with the fused mass flowing nozzle outside surface.
And, for fear of stress concentration etc. and make the intensity of fused mass flowing nozzle stronger, and in order easily to make external surface shape become the shape that melts is difficult to soak into rising, more preferably the flow path cross sectional area of first internal surface is certain, more preferably flowing path section is certain, most preferably first internal surface be shaped as cylindric.
Moreover in the present invention, so-called melts comprises the material that obtains after the fusions such as making inorganic composition, metal or organic composition thing, also can be melten glass, molten metal, molten resin etc.
(2) as (1) described fused mass flowing nozzle, when being made as exterior cross-section with the nozzle profile that the vertical cross section of smelt flow outgoing direction is presented, the area that exterior cross-section is thus surrounded is made as exterior cross-section when long-pending, the external surface shape of described fused mass flowing nozzle comprises at least: first outside surface, and it has the long-pending b1 of first exterior cross-section of outflow side; Second outside surface, it links to each other with described first outside surface, and its sectional area changes to the long-pending b2 of second exterior cross-section from the long-pending b1 of described first exterior cross-section; The 3rd outside surface, it links to each other with described second outside surface, and its sectional area changes to the long-pending b3 of the 3rd exterior cross-section from the long-pending b2 of described second exterior cross-section; And the surface all round, it links to each other with described the 3rd outside surface, and has the long-pending b3 of described the 3rd exterior cross-section, and described first exterior cross-section amass b1, described second exterior cross-section and is amassed the relation that b2, described the 3rd exterior cross-section amass b3 and satisfy b3＞b2＞b1.
(3) as (1) described fused mass flowing nozzle, when being made as exterior cross-section with the nozzle profile that the vertical cross section of smelt flow outgoing direction is presented, the area that exterior cross-section is thus surrounded is made as exterior cross-section when long-pending, the external surface shape of described fused mass flowing nozzle comprises at least: first outside surface, and it has the long-pending b1 of first exterior cross-section of outflow side; Second outside surface, it links to each other with described first outside surface, and its sectional area changes to the long-pending b3 of the 3rd exterior cross-section from the long-pending b1 of described first exterior cross-section; And the surface all round, it links to each other with described second outside surface, and has the long-pending b3 of described the 3rd exterior cross-section, and the long-pending b 1 of described first exterior cross-section satisfies b3＞b1 with the relation that described the 3rd exterior cross-section is amassed b3.
Form according to (2) and (3), even it is long-pending that the inflow side has big exterior cross-section, the intensity that also can keep mass flowing nozzle, and the exterior cross-section that can reduce the part of joining with end face portion is long-pending, and can make the outer shape that continues towards upstream side under the long-pending state of its little exterior cross-section keeping that forms of mass flowing nozzle front end, therefore, the situation tapered with directly upwards forming the scarp from the smelt flow outlet compared, and can suppress to rise from the infiltration of the effusive melts of fused mass flowing nozzle.Therefore, can stably flow out the melts of buttress shaft shape, the little melt drop of perhaps can stably dripping is so can form the spherical particle or the formed body of small melt drop or glass elements etc. with high weight precision.
Just in case melts soaks into when rising to first outside surface, can produce described devitrification problem, perhaps can't stably flow out melts, therefore the situation of the melts removing of rising can appear soaking into for the moment.
Form as (2), with the 3rd outside surface that links to each other with second outside surface is set between the surface all round at second outside surface, thus, this the 3rd outside surface plays a role as soaking into the rising return portion, described infiltration rising return portion is used to suppress to soak into the melts that rises and continues to soak into rising, even soaking into from first outside surface, melts rises to second outside surface, but owing to prevent that with this 3rd outside surface melts from soaking into rising, therefore can reduce and soak into the amount that rises, thereby be easy to remove the melts that soaks into rising.
And, soak into and to rise to first outside surface in order easily to suppress melts, more preferably the exterior cross-section of first outside surface is long-pending is certain, more preferably exterior cross-section is certain, most preferably first outside surface be shaped as cylindric.
(4) as each described fused mass flowing nozzle in (1) to (3), when area is made as d with the circular diameter that the flow path cross sectional area of close outflow side of described first internal surface equates, and when the long-pending circular diameter that equates of exterior cross-section of the most close outflow side of area and described first outside surface is made as D, the relation of the satisfied following numerical formula (1) of the relation of described d and D:
[numerical formula 1]
0.4＜d/D＜0.9 (1)。
According to this form, be easy to process accurately first internal surface of fused mass flowing nozzle, and fully improve the intensity of spout easily.And the wall thickness attenuation of end face portion rises to first outside surface thereby can more easily suppress the melts infiltration.
Improve intensity for further, and be easy to carry out high precision processing, the upper limit of the value of described d/D is more preferably below 0.88, most preferably below 0.85.
And, rising to first outside surface in order more easily to suppress the melts infiltration, the lower limit of the value of described d/D is more preferably more than 0.5, most preferably more than 0.55.
(5) as (2) or (4) described fused mass flowing nozzle, described exterior cross-section is similar shape, and the exterior cross-section of described second outside surface is long-pending to increase continuously towards described surperficial all round direction.
According to described form, exterior cross-section is similar shape, and the exterior cross-section of second outside surface is long-pending to increase continuously towards surperficial all round direction, promptly, the exterior cross-section of second outside surface is long-pending dwindles continuously towards the direction of first outside surface, therefore, outside surface shrinks to the outflow side from the inflow side of melts successively with level and smooth shape.When make it softening to soaking into operations such as the melts that rises to second outside surface heats through first outside surface, and utilize gravity etc. that this melts is fallen and when it is removed, because second outside surface shrinks successively with level and smooth shape, soak into the melts that rises so can easily remove.
(6) as each described fused mass flowing nozzle in (1) to (5), described flowing path section is similar shape, and the flow path area of described second internal surface increases continuously towards the direction of described the 3rd internal surface.
According to described form, flowing path section is similar shape, and the flow path area of second internal surface increases continuously towards the direction of the 3rd internal surface, promptly, the flow path area of second internal surface dwindles continuously towards the direction of first internal surface, therefore, the stream internal surface of smelt flow warp shrinks to the outflow side from the inflow side of melts successively with level and smooth shape.Therefore, when melts flows out, even smelt flow is shunk to the little outflow side of flow path area from the big inflow side of flowing path section, melts is not flowed in stream by also can on opposing ground, and the part that melts can not occur is trapped in the interior situation of stream of fused mass flowing nozzle, thereby change and the uniform spherical particle of quality do not take place to form in formation easily.
(7) as (5) described fused mass flowing nozzle, by being parallel on smelt flow outgoing direction and the cross section that the plane intercepted by described fused mass flowing nozzle center, the angle θ 1 that described second outside surface is become is 5～120 degree.
If be limited on the angle θ 1 that second outside surface is become below 120 degree, then can more easily remove and soak into the melts that rises to second outside surface through first outside surface.Its reason is, soak into the melts that rises softening after, melts can not isolate into island, but can with on every side the remollescent melts flow and fall downwards.In order more easily to obtain described effect, the upper limit of the angle θ 1 that second outside surface is become is more preferably below 110 degree, most preferably below 100 degree.
And, if the angle θ 1 that second outside surface is become is that then surperficial all round exterior cross-section is amassed and become big, obtains high-intensity fused mass flowing nozzle easily more than 5 degree.In order to obtain the higher fused mass flowing nozzle of intensity, the lower limit of the angle θ 1 that second outside surface is become is more preferably more than 30 degree, most preferably more than 60 degree.
(8) as (7) described fused mass flowing nozzle, by being parallel on smelt flow outgoing direction and the cross section that the plane intercepted by described fused mass flowing nozzle center, the angle θ 2 that described second internal surface is become is 5～120 degree.
If be limited to 120 degree on the angle θ 2 that second internal surface is become, the part that then will more be difficult to take place melts is trapped in the situation in the stream of fused mass flowing nozzle.In order more easily to obtain described effect, the upper limit of the angle θ 2 that second internal surface is become is more preferably below 110 degree, most preferably below 100 degree.
On the other hand, when the length of the smelt flow outgoing direction of guaranteeing first outside surface is length more than the certain numerical value, and the wall thickness of guaranteeing the fused mass flowing nozzle of the part that clipped by second outside surface and second internal surface is when being thickness more than the certain numerical value, the angle θ 2 that is become along with second internal surface diminishes, must increase the length of the smelt flow outgoing direction of first internal surface, therefore, make the perforate processing that utilizes drill bit to carry out become difficult easily.Therefore, from being easy to carry out described processing view, more than the lower limit of the angle θ 2 that second internal surface is become preferred 5 is spent, more preferably more than 30 degree, most preferably more than 60 degree.
(9) as (8) described fused mass flowing nozzle, described angle θ 1 is identical with described angle θ 2.
According to described form, second outside surface is parallel with second internal surface, and the interval of second outside surface and second internal surface is certain, that is, the wall thickness of rake that constitutes second outside surface and second internal surface is certain, therefore, stress can not concentrated and be created in the little part of wall thickness, therefore forms good intensity.And, can reduce material cost.
(10) as (2) described fused mass flowing nozzle, by being parallel on smelt flow outgoing direction and the cross section that the plane intercepted by described fused mass flowing nozzle center, described the 3rd outside surface with described all round the angle θ 3 that become of surface be 70～110 degree.
If as the 3rd outside surface that soaks into the rising return portion with all round the angle θ 3 that become of surface on be limited to 110 spend below, even then rise to first outside surface just in case melts soaks into, even soak into when rising to second outside surface, also can easily stop melts to soak into to rise to the surface all round, and can easily remove and soak into the melts that rises.In order more easily to obtain described effect, the upper limit of the angle θ 3 that is become is more preferably below 100 degree, most preferably below 95 degree.
If the 3rd outside surface with all round the following of angle θ 3 that become of surface be limited to more than 70 degree, then processing is used for forming the 3rd outside surface that soaks into the rising return portion easily.In order to make described processing more easy, the lower limit of the angle θ 3 that is become is more preferably more than 80 degree, most preferably more than 85 degree.
(11) as each described fused mass flowing nozzle in (1) to (10), described flowing path section is circle.
(12) as (2) to (5), and (7) to (10) in each described fused mass flowing nozzle, described exterior cross-section for the circle.
According to the form of (11) and (12), because flowing path section and exterior cross-section are circle, thus excellent in workability, nor can waste employed material.And, because the outflow shape of the melts after flowing out from the spout of fused mass flowing nozzle is cylindric, so can make spherical particle accurately.
(13) as (4) described fused mass flowing nozzle, described diameter d is 0.15～3.5mm.
The diameter of the internal surface of fused mass flowing nozzle spout, can be according to the size of the spherical particle of wanting to make and suitably design, and when first internal surface with the vertical direction of smelt flow outgoing direction on the cross-sectional shape that intercepts when circular, if the following of the diameter of first internal surface is limited to more than the 0.15mm, then can easily obtain the fused mass flowing nozzle that when making small spherical particle, has abundant intensity.In order easily to obtain described effect, the lower limit of inner surface diameter is more preferably more than the 0.16mm, most preferably more than the 0.17mm.
And, with regard to fused mass flowing nozzle of the present invention, when first internal surface with the vertical direction of smelt flow outgoing direction on the cross-sectional shape that intercepts when circular, even the diameter of first internal surface is greater than 3.5mm also no problem, if but the diameter of first internal surface is below the 3.5mm, then can more highlight problem of the present invention, and effect of the present invention is also bigger.In order easily to obtain small spherical particle, the diameter of the internal surface of fused mass flowing nozzle spout is more preferably below the 3.0mm, most preferably below the 2.0mm.
(14) as (2) described fused mass flowing nozzle, length that described the 3rd outside surface demonstrates on following cross section 1 is for more than the 0.01mm, and described cross section is by being parallel to the smelt flow outgoing direction and the plane by described fused mass flowing nozzle center is intercepted.
If the length of the 3rd outside surface 1 is more than the 0.01mm, then suppresses melts easily and soak into and to rise to the surface all round.In order more easily to obtain described effect, the lower value of the length 1 of the 3rd outside surface is more preferably more than the 0.1mm, most preferably more than the 0.3mm.
