Description

  The present invention relates to a metal material refinement apparatus that can refine the structure of a metal material.

  In Patent Document 1, a container having a material storage chamber for loading a metal material is made independent of an upper punch and a lower punch so that the container can be rotated, and the upper punch and / or the lower punch are pressed against the metal material. In addition, a technique is disclosed in which the lower punch is rotated about its axis to relatively shear the material, thereby repeatedly applying a strain to the metal material in the material accommodating chamber. According to this document, it is described that the structure of the metal material can be refined because the strain due to the shear deformation is repeatedly applied to the metal material in the material accommodation chamber.

In Patent Document 2, in a forward extrusion method in which a material loaded in a material storage chamber of a container having a die hole is pushed by a punch, the material in the container is punched from the die hole while rotating the container or the punch. A torsional forward extrusion method that pushes forward is disclosed. Also in this case, it is described that the structure of the metal material can be refined because the metal material in the material storage chamber is repeatedly subjected to strain due to shear deformation.
Japanese Patent No. 3616591 JP-A-2005-990

  According to the technology according to Patent Document 1, a method is adopted in which the material obtained by rotating the upper punch and / or the lower punch is relatively shear-deformed while the upper punch and / or the lower punch are pressed against the metal material. Therefore, the shear deformation imparted to the material is not necessarily sufficient, and the effect of miniaturizing the material is not necessarily sufficient.

  Further, according to the technique according to Patent Document 2, since a method of applying a shear deformation to a material by rotating a container or punch that accommodates the material is employed, the shear deformation applied to the material is not necessarily sufficient. Also, the effect of reducing the size is not always sufficient. Therefore, in the industry, further development of an apparatus for efficiently miniaturizing a metal material structure is underway.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a novel metal material refining apparatus capable of efficiently miniaturizing a structure of a metal-based material.

  A metal material refinement apparatus according to the present invention includes: (i) a base having a machining space having an axial core; and (ii) a processing space of the base that is fitted so as to be able to advance along the axial core. A pressure body having a pressure surface that pressurizes a metal-based material; and (iii) a pressure receiver having a pressure reception surface fitted in the processing space of the base so as to face the pressure surface of the pressure body with a predetermined interval. And (iv) provided in the processing space between the pressure surface of the pressure body and the pressure receiving surface of the pressure receiving body, dividing the processing space into the pressure space on the pressure body side and the pressure receiving space on the pressure body side, and And (v) the obstruction member is provided so as to communicate the pressurization space and the pressure reception space, and the pressurization body. While pressing the material of the pressurizing space by the advance of the obstruction member, the base and the pressurizing body It is characterized in that when at least one is rotated with respect to the axial center of the processing space, a material passage is provided that allows the material to flow into the pressure receiving space while applying shear deformation to the material from the pressure space toward the pressure receiving space. To do. The rotation can be appropriately adjusted depending on the material, the required degree of miniaturization, etc., and may be continuous rotation or intermittent rotation. The rotation angle is not particularly limited, and may be rotated around the axis at a plurality of 360 ° or more, or may be 360 ° or less depending on the material, the required degree of miniaturization, and the like.

  According to the metal material refinement apparatus according to the present invention, since the material of the pressurizing space is pressurized by the advancement of the pressurizing body, the material of the pressurizing space passes through the material passage of the obstacle member and receives the pressure receiving space. Head for. Furthermore, at least one of the obstruction member, the base, and the pressurizing body is rotated with respect to the axial center of the processing space. Thereby, when the material which goes to a pressure receiving space from a pressurization space passes the material passage way of an obstruction member, distortion by shear deformation is given to the material which passes a material passage way. For this reason, the structure of the material can be made fine.

  In particular, when the metal-based material is a material in which the hard phase is dispersed in the matrix phase, it can be expected that the hard phase is divided by shearing when the material is subjected to shear deformation. In this case, even when the hard phase contained in the structure of the material is coarsened, it can be expected to make the hard phase fine. The hard phase means a phase that is harder than the matrix of the material and dispersed in the matrix. Examples of the hard phase include primary crystals, intermetallic compounds, oxides, carbides, and silicides.

  By the way, when rotating at least one of the obstruction member, the base, and the pressurizing body with respect to the axial center of the processing space to give the material distortion due to shear deformation, the central region in the direction perpendicular to the axis in the pressurizing space And the outer edge region in the direction perpendicular to the axis in the pressurization space have different rotational radii from the shaft core, etc. May not be uniform.

  That is, in the central region in the direction perpendicular to the axis in the pressurizing space, the rotational radius from the axis is relatively small, so that the flow rate of the material is relatively low, and there is little or no shear force. It is easy to become a position or a pseudo neutral position. For this reason, the material refinement effect in the central region is relatively small compared to the material refinement effect in the outer edge region. On the other hand, in the outer edge region in the direction perpendicular to the axis in the pressurizing space, since the turning radius from the axis is relatively large compared to the central region in the direction perpendicular to the axis, the magnitude of the shearing force is large, The effect of miniaturization based on shear deformation, and hence strain due to shear deformation, is relatively large. For this reason, if the material is refined in both the central region and the outer edge region of the obstacle member, the variation in the refinement effect may be increased.

  Therefore, according to the present invention, in order to reduce the variation in the miniaturization effect, the central region in the direction perpendicular to the axis of the machining space axis is obstructed by the obstacle member against the material flow in the pressurizing space. Preferably, the material passage is located outside the obstacle region of the obstacle member in the direction perpendicular to the axis (claim 2). In this case, in the obstructing member, in the central region in the direction perpendicular to the axis, which causes variation in the refinement of the material structure, that is, in the obstructing region (prone to become a neutral position or a pseudo-neutral position), the structure refining process based on strain due to shear deformation Is suppressed. As a result, it is advantageous to reduce the variation in the structure refinement effect in the entire material.

  Further, according to the present invention, the obstruction member includes an obstruction area that can obstruct the flow of the material in the pressurization space in the central area in a direction perpendicular to the axis with respect to the axial center of the processing space. It is preferable that a material guide part for allowing the material to flow toward the material passage is provided in the obstacle region. In this case, since the material in the obstacle region flows toward the material passage by the material guide portion, the material guide portion suppresses the material from staying in the obstacle region. In this case, it is advantageous to achieve the miniaturization process while suppressing the stagnation of the material.

  Further, according to the present invention, it is preferable that a first drive unit that moves the pressure member in a direction to approach the obstacle member and a second drive unit that moves the pressure receiver in a direction to move away from the obstacle member are preferably provided. In this case, the pressure body can be moved away from the obstacle member by the second drive section while the pressure body is brought closer to the obstacle member by the first drive section. For this reason, it becomes easy to flow the material in the pressurizing space from the pressurizing space into the pressure receiving space through the material passage.

  According to the invention, there is provided a drive source for rotating at least one of the obstacle member, the base, and the pressurizing body around the axis of the processing space, and the drive source is the obstacle member, the base. The drive member having a drive tooth portion that meshes with a tooth portion formed on the outer peripheral portion of at least one of the pressurizing bodies and the engagement between the tooth portion and the drive tooth portion of the drive member are advanced, so that the processing space is increased. It is preferable to have a drive motor that rotates at least one of the obstacle member, the base, and the pressurizing body around the axis. In this case, when the drive motor is driven to rotate, the engagement between the drive tooth portion of the drive member and at least one tooth portion of the obstacle member, the base portion, and the pressurizing body proceeds. Accordingly, at least one of the obstacle member, the base, and the pressurizing body is rotated around the axis of the processing space. As a result, the material passing through the material passage of the obstacle member can be distorted by shear deformation, and the material structure can be made fine.

  Further, according to the present invention, in the cross section obtained by cutting the obstacle member in the thickness direction, the material passage is in a direction different from the first hole portion having the first hole core and the first hole core of the first hole portion. It is preferable that at least a second hole core that includes the inclined second hole core and communicates with the first hole portion is provided. In this case, distortion due to shear deformation is effectively applied to the material passing through the material passage, so that the structure of the material becomes fine.

  Further, according to the present invention, in the cross section obtained by cutting the obstacle member in the thickness direction, the material passage way allows the material to flow in a direction different from the direction in which the material flows relative to the obstacle member in the pressurized space. It is preferable to be inclined (claim 6). In this case, since the amount of strain applied to the material passing through the material passage becomes large, the material structure becomes fine.

  According to the present invention, in the cross section obtained by cutting the obstructing member in the thickness direction, the material passage path preferably includes a hole core along a direction parallel to the axial center of the processing space. In this case, since the material passing through the material passage is distorted by shear deformation, the material structure becomes fine.

  According to the present invention, when the material passage is viewed in a direction parallel to the axial center of the processing space, the material passage is at least one of a circular shape, a quadrangular shape, a triangular shape, a pentagonal shape, and a hexagonal shape. It is preferable to have a shape. The circular shape includes a perfect circle, an ellipse, an ellipse, and the like.

  According to the present invention, the obstacle member that divides the pressurizing space in which the material is pressurized and the pressure receiving space for receiving the material includes the material passage. The material passageway processes the at least one of the obstacle member, the base, and the pressurizing body while communicating the pressurizing space and the pressure receiving space and pressurizing the material of the pressurizing space by the advancement of the pressurizing body. Rotate with respect to the space axis. Thereby, distortion due to shear deformation can be applied to the material from the pressurizing space to the pressure receiving space, and the structure of the metal-based material flowing through the material passage can be efficiently refined.

(Embodiment 1)
Embodiment 1 of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, the metal material refinement apparatus according to the present embodiment includes a base 1, a pressure body 2, a pressure receiver 3, and an obstacle member 4. The base 1 includes a machining space 10 having a vertical cylindrical shape having an axial core P1 extending in the vertical direction. The base 1 is divided into two in the direction in which the axis P1 extends, and an upper cylindrical first base 11 that functions as a container and a lower cylindrical second base 12 that functions as a container. And.

  The pressurizing body 2 can function as an upper punch and is fitted in the machining space 10 of the first base portion 11 of the base portion 1 so as to be capable of moving forward and backward along the axis P1, and is a circle along the direction perpendicular to the axis. It has a flat pressure surface 20 that is shaped. The pressurizing body 2 pressurizes the metal-based material loaded in the machining space 10 by moving forward in the forward direction (arrow Y1 direction). The pressurizing body 2 has a bowl-shaped pressurizing portion 21 having a pressurizing surface 20 and a shaft portion 22 that is coaxially and continuously connected to the pressurizing portion 21 upward. The distal end portion of the shaft portion 22 is connected to a first drive portion 28 that moves the pressurizing body 2 forward and backward. The first drive unit 28 is a fluid pressure mechanism such as a hydraulic mechanism or a pneumatic mechanism.

  As shown in FIG. 1, the pressure receiving body 3 can function as a lower punch, and has a flat pressure receiving surface 30 having a circular shape along a direction perpendicular to the axis for receiving the pressurized material. The pressure receiving body 3 is fitted in the processing space 10 of the second base portion 12 of the base portion 1 so as to face the pressure surface 20 of the pressure body 2 with a predetermined interval. The pressure receiving body 3 includes a bowl-shaped pressure receiving portion 31 having a pressure receiving surface 30, and a shaft portion 32 connected to the pressure receiving portion 31. The distal end portion of the shaft portion 32 is connected to a second drive portion 39 that moves the pressure receiving surface 30 forward and backward. The second drive unit 39 is a fluid pressure mechanism such as a hydraulic mechanism or a pneumatic mechanism.

  As shown in FIG. 1, the obstruction member 4 has a plate shape having an upper surface 4 u and a lower surface 4 d facing each other, and between the pressure surface 20 of the pressure body 2 and the pressure surface 30 of the pressure body 3. It is provided in the processing space 10 located and traverses in the radial direction of the processing space 10. As a result, the obstacle member 4 partitions the processing space 10 into a pressurizing space 15 having a cylindrical shape on the pressure body 2 side and a pressure receiving space 16 having a cylindrical shape on the pressure body 3 side.

  FIG. 2 shows a plan view of the obstruction member 4. As shown in FIG. 2, the obstruction member 4 has a plurality of arm-shaped connecting portions 41 that can function as shear applying portions that form a plurality of material passage paths 40. The plurality of connecting portions 41 are arranged on the axis P1 of the obstacle member 4 so as to cross in the radial direction of the machining space 10 and to make an equal angle θ (120 °) in the circumferential direction with respect to the axis P1. On the other hand, it extends in the radial direction. The number of arm-shaped connecting portions 4 is not limited to three, and may be two, four, five or more.

  The material passageway 40 penetrates in the thickness direction of the obstacle member 4 so as to allow the pressurizing space 15 and the pressure receiving space 16 to communicate with each other. As shown in FIG. 2, the arcuate wall surface 40a and the radial wall surface are formed. It is divided by 40b and 40c. When the material passage 40 is viewed in a direction parallel to the axis P1 of the processing space 10, the material passage 40 is perpendicular to the axis P1 of the obstruction member 4 (arrow X direction, radial direction of the obstruction member 4). The shape gradually expands with increasing distance, that is, a substantially fan shape in which the axis P1 side is narrowed. The obstruction member 4 is configured to be able to rotate about the axis P1 independently of the base 1.

  As shown in FIG. 1, the ring portion 42 formed on the outer peripheral side of the obstacle member 4 makes one round around the axis P <b> 1, and forms a ring shape with the first sliding surface 47 that forms a ring shape. And a second sliding surface 48. Here, the ring member 42 is rotated around the axis P1 by an unillustrated drive source (for example, a drive motor or a fluid pressure cylinder device), and as a result, the obstacle member 4 is in the state where the base 1 is fixed. It rotates continuously or intermittently around P1.

  In FIG. 2, an arrow X direction indicates a direction perpendicular to the axis P <b> 1 of the machining space 10. In the obstruction member 4, an obstruction area 43 is formed in the central area 4 c in the direction perpendicular to the axis (arrow X direction, radial direction). The obstruction area 43 is an area that obstructs the material flow from the processing space 15 toward the pressure receiving space 16 and restricts the material flow. As shown in FIG. 2, the obstacle region 43 is a region that connects the inner ends of the connecting portion 41 that extends in the direction perpendicular to the axis (the direction of the arrow X, the radial direction). When the material of the pressurizing space 15 is pressed against the pressurizing surface 20 of the pressurizing body 2 and hits the obstacle region 43 and interferes with the obstacle region 43, the material in the pressurizing space 15 flows directly toward the pressure receiving space 16. Is restricted and flows from the obstacle region 43 toward the material passage 40 in the radially outward direction (arrow DA direction). For this reason, the material passage 40 is provided outside the obstacle region 43 of the obstacle member 4 in the direction perpendicular to the axis (the arrow X direction) (see FIG. 2).

  According to the present embodiment, the obstacle member 4 is rotatable around the axis P <b> 1 of the processing space 10, and is a rotating member that rotates in the direction of the arrow R <b> 1 with respect to the material in the pressurizing space 15. Can function as. According to the present embodiment, as shown in FIG. 1, the obstruction member 4 includes an inner member 44 and an outer member 45 connected to the inner member 44. The inner member 44 has a material passage 40, a connecting portion 41, and a failure region 43.

  As shown in FIG. 1, the outer member 45 is integrated with the inner member 44 so as to be positioned outside the inner member 44 in the direction perpendicular to the axis (the direction of the arrow X). The ring portion 42 of the outer member 45 includes a first sliding surface 47 that rotates while being guided by the first guide surface 11 i on the outer peripheral side of the first base portion 11, and a second guide surface 12 i on the outer peripheral side of the second base portion 12. And a second sliding surface 48 that is guided and rotated. Therefore, the obstruction member 4 is guided by the first guide surface 11i of the first base portion 11 and the second guide surface 12i of the second base portion 12 together with the inner member 44 and the outer member 45, and rotates around the axis P1. . In addition, the rotation attitude | position of the obstruction member 4 is stabilized by the 1st guide surface 11i and the 2nd guide surface 12i.

  A lubricant 47r is interposed between the first guide surface 11i and the first sliding surface 47. A lubricant 48r is interposed between the second guide surface 12i and the second sliding surface 48. The lubricants 47r and 48r may be solid lubricants such as graphite and molybdenum disulfide, or liquid lubricants such as lubricating oil. A bearing may be interposed instead of the lubricant.

  In use, a metal material of a predetermined size is accommodated in the pressurized space 15. The material loaded in the pressurized space 15 may be any of a hot state, a warm state, and a cold state, but the hot state and the warm state are preferable in order to ensure the fluidity of the material. . In a state where the material is accommodated in the pressurizing space 15, the pressurizing body 2 is advanced in the pressurizing direction (arrow Y1 direction, downward direction) along the axis P1 by the first driving unit 28. As a result, the material of the pressurizing space 15 passes through the material passage 40 of the obstructing member 4 little by little while contacting the obstructing member 4, and the arrow DB direction from the pressurizing space 15 toward the pressure receiving space 16 (see FIG. 1). To flow. Further, the obstacle member 4 rotates continuously or intermittently with respect to the axis P1 of the machining space 10.

  According to this embodiment, the rotation speed and total number of rotations of the obstruction member 4 are the composition of the material, the volume of the material loaded in the pressurized space 15, the material of the hard phase when the material has a hard phase, etc. Although it selects suitably according to, 0.1-20 rpm, 0.3-10 rpm, 0.5-5 rpm is illustrated. However, it is not limited to these. In processing the material of the pressurized space 15, the total number of rotations is 2 to 100 times, 3 to 50 times, 5 to 20 times, and 7 to 12 times. However, it is not limited to these. The rotation may be continuous rotation or intermittent rotation.

  As described above, when the obstruction member 4 rotates, the material that passes from the pressurizing space 15 through the material passage 40 toward the pressure receiving space 16 is strained by shear deformation. Since the pressurizing space 15 communicates with the pressure receiving space 16 via the material passage 40, all or most of the material passing from the pressurizing space 15 through the material passage 40 toward the pressure receiving space 16 is strained by shear deformation. Is given. As a result, refinement of the texture of the processed material proceeds.

  In particular, when the metal-based material is a material in which a hard phase is dispersed in the matrix phase, when the material is subjected to strain due to shear deformation, the hard phase dispersed in the matrix phase of the material is separated by shearing. By making it, it can be expected to make the hard phase fine. For this reason, even if a hard phase is coarse, a hard phase can be refined | miniaturized. Therefore, mechanical properties such as the strength of the material can be improved, and the quality of the material can be improved.

  Here, the hard phase is harder than the parent phase, and although it can improve wear resistance, there is a risk of excessive attack on the other party and loss of the hard phase, so avoid coarse hard phases. Is often preferred. As described above, even when the metal-based material is a material in which the hard phase is dispersed in the matrix phase, when the material is subjected to strain due to shear deformation, not only the structure of the material is refined, The hard phase dispersed in the matrix phase can be separated by shearing, and it can be expected to make the hard phase fine. For this reason, mechanical properties such as strength, wear resistance, and slidability of the material can be further improved, and the quality of the material can be further improved.

  According to the present embodiment, when the processing for refining the material as described above is performed, the material that has passed through the material passage 40 is received by the pressure receiving surface 30 of the pressure receiving body 3 when reaching the pressure receiving space 16. The pressure receiving body 3 that has received the material at the pressure receiving surface 30 is biased in a pressure receiving direction (arrow Y2 direction, upward) opposite to the pressurizing direction (arrow Y1 direction, downward) of the pressure body 2.

  According to this embodiment, examples of the material loaded in the pressurizing space 15 include an aluminum alloy, a magnesium alloy, a copper alloy, a zinc alloy, and an iron alloy. However, it is not limited to these. In this case, a hypoeutectic composition, a hypereutectic composition, or a eutectic composition may be used. Examples of the aluminum alloy include an Al—Si alloy, an Al—Mg alloy, an Al—Cu alloy, and an Al—Zn alloy. Accordingly, the aluminum alloy can contain one or more of Si, Mg, Cu, and Zn. In the case of an Al—Si alloy, one containing silicon particles as the hard phase can be employed. In the case of an aluminum alloy, one or two of Si: 0.5 to 20%, Cu: 0.5 to 7%, Mg: 0.5 to 5%, Fe: 1 to 7% by mass ratio The above can be included. Examples of the magnesium alloy include Mg—Al alloys, Mg—Zn alloys, Mg—Cu alloys, Mg—Si alloys, and the like. Accordingly, the magnesium alloy can contain one or more of Al, Si, Mg, Cu, and Zn.

  According to the present embodiment, the material loaded in the pressurized space 15 may be any one of a hot state, a warm state, and a cold state. However, in order to ensure the fluidity of the material, etc. A hot state and a warm state are preferable. For example, when the material is an aluminum alloy, the temperature of the material can be maintained at 150 to 400 ° C, 300 to 370 ° C, and 340 to 360 ° C. However, it is not limited to these. When the material is in a hot state or a warm state, it is preferable that the first base portion 11 and the second base portion 12 are also heated in the temperature region or in the vicinity of the temperature region. Similarly, the pressurizing body 2 and the pressure receiving body 3 are preferably heated in the temperature range or in the vicinity of the temperature range. However, it may not be heated depending on conditions, and the first base portion 11, the second base portion 12, the pressurizing body 2 and the pressure receiving body 3 may be in a normal temperature region.

  As described above, according to the present embodiment, since the material of the pressurizing space 15 is pressurized by the advancement of the pressurizing body 2, the material of the pressurizing space 15 passes through the material passage 40 of the obstacle member 4. To the pressure receiving space 16. Here, although the bases 11 and 12 are fixed, the obstacle member 4 is rotated continuously or intermittently around the axis P <b> 1 of the machining space 10. Thereby, when the material which goes to the pressure receiving space 16 from the pressurization space 15 passes the material passageway 40 of the obstruction member 4, the material which passes the material passageway 40 is given distortion by shear deformation. In this way, since the material passing through the material passage 40 is distorted by shear deformation, the material structure becomes fine.

  In particular, when the metal-based material is a material in which the hard phase is dispersed in the matrix phase, when the material is strained by shear deformation, the hard phase is divided by shearing to make the hard phase fine. I can expect that.

  By the way, when the obstacle member 4 is rotated around the axis P1 of the processing space 10 to refine the material structure, the central region 4c in the direction perpendicular to the axis (arrow X direction, radial direction) in the pressurizing space 15 is used. And the magnitude of the shearing force is not necessarily uniform between the outer edge region 4p in the direction perpendicular to the axis in the pressurizing space 15 (arrow X direction). The reason for this is that in the central region 4c in the direction perpendicular to the axis in the pressurizing space 15 (in the direction of the arrow X), the turning radius from the axis P1 is relatively small, so the material flow rate is relatively low. The strain due to the shear deformation applied to the material is small as compared with the outer edge region 4p, and the neutral position or the pseudo neutral position where the strain due to the shear deformation is small or not generated.

  On the other hand, in the outer edge region 4p in the direction perpendicular to the axis in the pressurizing space 15 (arrow X direction), the rotational radius from the axis P1 is relatively large. It is relatively large compared to the fault area 43 on the side. In this case, if the structure is refined in the central region 4c and the outer edge region 4p of the obstacle member 4, the strain due to the shear deformation applied to the material may be a factor of variation. For this reason, there is a possibility that the material refinement effect may vary in the central region 4c and the outer edge region 4p of the obstacle member 4. In this case, there is room for improvement from the viewpoint of homogenization of the entire material.

  In this regard, according to the present embodiment, in the obstacle member 4, the central region 4c (region in which the micronization effect is relatively low) in the direction perpendicular to the axis P1 of the machining space 10 with respect to the axis P1 (arrow X direction, radial direction). In addition, an obstacle region 43 that obstructs the flow of material in the pressurized space 15 is provided. In the direction perpendicular to the axis (the direction of the arrow X), the material passage 40 is provided outside the obstacle region 43 of the obstacle member 4. According to the present embodiment in which such a configuration is adopted, in the central region 4c that is the neutral position or the pseudo-neutral position in the vicinity of the axis P1 of the obstacle member 4, the material facing the obstacle region 43 is fine in structure. The materializing effect is not sufficiently performed, and the material is directed to the material passage 40 located on the outside and having a high tissue refining effect, and is refined by the material passage 40. For this reason, the dispersion | variation in the refinement | miniaturization effect with respect to the whole material is reduced. For this reason, even when the material has a coarse hard phase (for example, primary crystal silicon particles), the hard phase can be divided and reduced in size, and the material characteristics such as strength, wear resistance, opponent attack, etc. Can be improved.

  According to this embodiment, as shown in FIG. 1, the 1st drive part 28 which drives the pressurization body 2 is provided. The first drive unit 28 can move the pressurizing body 2 in a direction (arrow Y1 direction) approaching the obstacle member 4 and can move in a direction away from the obstacle member 4 (arrow Y2 direction). Further, a second drive unit 39 for driving the pressure receiving body 3 is provided. The second drive unit 39 moves the pressure receiving body 3 in the direction approaching the obstruction member 4 (arrow Y2 direction) and moves the pressure receiving body 3 away from the obstruction member 4 (arrow Y1 direction). Here, the driving force F1 for driving the pressurizing body 2 in the pressurizing direction (arrow Y1 direction, downward) is made larger than the driving force F2 for driving the pressure receiving body 3 in the pressure receiving direction (arrow Y2 direction, upward). (F1> F2). For this reason, the pressurizing body 2 and the pressure receiving body 3 can be moved in the processing advancing direction (arrow Y1 direction, downward) while urging the pressurizing body 2 and the pressure receiving body 3 in opposite directions. For this reason, it is suppressed that the material in the pressurization space 15 passes the material passage 40 rapidly. Therefore, while suppressing the speed at which the material in the pressurizing space 15 passes through the material passage 40, the material in the pressurizing space 15 can be effectively strained by the shear deformation by the rotation of the obstacle member 4, As a result, the material can be effectively miniaturized. Therefore, even when the material includes a hard phase, the hard phase can be effectively divided.

  The driving forces F1 and F2 are appropriately set according to the moving speed at which the pressurizing body 2 and the pressure receiving body 3 are moved in the processing progress direction. By adjusting the driving forces F1 and F2, the speed at which the material passes through the material passage 40 can be adjusted. That is, basically, if F1−F2 = ΔF is reduced while satisfying the condition of F1> F2, the speed at which the material passes through the material passage 40 can be reduced. If F1−F2 = ΔF is increased, the speed at which the material passes through the material passage 40 can be increased.

  Furthermore, according to the present embodiment, the upper surface 4u of the obstruction member 4 has a planar shape along the direction perpendicular to the axis, and the pressing surface 20 of the pressing body 3 also has a planar shape along the direction perpendicular to the axis. And the upper surface 4 u can effectively hold the material, which is advantageous for carrying out the miniaturization process by passing all or most of the material of the pressurized space 15 through the material passage 40.

  According to this embodiment, the first base portion 11 and the second base portion 12 can be made of metal or ceramics. The pressurizing body 2 and the pressure receiving body 3 can be formed of metal or ceramics. In the case of metal, heat resistant steel can be used. An example of the heat resistant steel is an SKD material.

(Embodiment 2)
3 to 5 show the second embodiment. This embodiment has basically the same configuration and the same function and effect as the first embodiment. The metal material refinement apparatus includes a base 1, a pressure body 2, a pressure receiver 3, and an obstacle member 4. In the obstructing member 4, portions other than the plurality of material passage paths 40 have a plurality of connecting portions 41 that can function as a shearing applying portion that imparts strain due to shear deformation to the material. The obstruction member 4 has a plate shape having an upper surface 4u and a lower surface 4d. The material passageway 40 penetrates the obstacle member 4 in the thickness direction thereof so that the pressurizing space 15 and the pressure receiving space 16 communicate with each other.

  FIG. 4 is a plan view in which the material passage 40 is visually recognized in a direction parallel to the axis P1 of the machining space 10. FIG. 5 shows a sectional view of the vicinity of the material passage 40 cut along a direction parallel to the axis P1. As shown in FIG. 4, the material passage 40 has an inner wall surface 40f having a circular shape (including a perfect circle and a pseudo perfect circle), and has a hole core ma parallel to the axis P1. The inner wall surface 40f is formed along the hole core ma. The obstruction member 4 is configured to be able to rotate about the axis P1 independently of the base 1.

  In the obstruction member 4, an obstruction area 43 is formed in the central area 4 c in the direction perpendicular to the axis P 1 of the machining space 10 with respect to the axis P <b> 1. The obstruction area 43 corresponds to an area that can obstruct the material flow. As shown in FIG. 4, the plurality of material passages 40 surround the obstacle region 43. Here, when the material of the pressurizing space 15 hits the obstacle region 43 and interferes, the advance of the material in the pressurizing space 15 toward the pressure receiving space 16 is limited. The material passage 40 is provided outside the obstacle region 43 of the obstacle member 4 in the direction perpendicular to the axis (the direction of the arrow X). The obstruction member 4 is rotatable in the direction of the arrow R1 around the axis P1 of the processing space 10, and can function as a rotation member that rotates with respect to the material in the pressurizing space 15.

  According to the present embodiment, as illustrated in FIG. 3, the obstacle member 4 includes an inner member 44 and an outer member 45 that is connected to the inner member 44. The inner member 44 has a material passage 40, a connecting portion 41, and a failure region 43. The outer member 45 is integrated with the inner member 44 so as to be positioned outside the inner member 44 in the direction perpendicular to the axis (the arrow X direction).

  Also in the present embodiment, the material is accommodated in the pressurizing space 15 during use. The material loaded in the pressurized space 15 may be any of a hot state, a warm state, and a cold state, but the hot state and the warm state are preferable in order to ensure the fluidity of the material. . For example, when the material is an aluminum alloy, the temperature of the material can be maintained at 200 to 400 ° C, 300 to 380 ° C, and 340 to 360 ° C. However, it is not limited to these. In this state, the pressurizing body 2 is advanced in the forward direction (arrow Y1 direction, downward direction) along the axis P1 by the first drive unit 28. Thereby, the material of the pressurizing space 15 passes through the material passage 40 of the obstacle member 4 and flows from the pressurizing space 15 toward the pressure receiving space 16. Further, the obstacle member 4 rotates with respect to the axis P1 of the machining space 10. As a result, strain due to shear deformation is imparted to the material passing from the pressurizing space 15 through the material passage 40 toward the pressure receiving space 16. As a result, the refinement of the material structure proceeds. In particular, since the pressurizing body 2 advances in the forward direction, the material is gradually moved from the pressurizing space 15 to the pressure receiving space 16.

  As described above, according to the present embodiment, as described above, since the material of the pressurizing space 15 is pressurized by the advancement of the pressurizing body 2, the material of the pressurizing space 15 passes through the material of the obstacle member 4. It passes through the path 40 toward the pressure receiving space 16. Further, the obstacle member 4 is rotated around the axis P1 of the processing space 10. As a result, when the material from the pressurizing space 15 toward the pressure receiving space 16 passes through the material passage 40 of the obstacle member 4, the obstacle member 4 rotates around the axis P <b> 1. The material passing through 40 is distorted by shear deformation. In this way, since the material passing through the material passage 40 is distorted by shear deformation, the material structure becomes fine. In particular, when the metal-based material is a material in which the hard phase is dispersed in the matrix phase, when the material is strained by shear deformation, the hard phase is divided by shearing to make the hard phase fine. I can expect that.

  By the way, as in the case of the first embodiment, when the obstacle member 4 is rotated around the axis P1 of the processing space 10 to refine the material structure, the direction perpendicular to the axis in the pressurizing space 15 (arrow) In the central region 4c in the X direction) and the outer edge region 4p in the direction perpendicular to the axis in the pressurizing space 15 (in the direction of the arrow X), the magnitude of the shearing force is not necessarily uniform, and thus the degree of the refinement effect is not necessarily limited. It is not uniform. The reason for this is that in the central region 4c in the direction perpendicular to the axis in the pressurizing space 15 (in the direction of the arrow X), the turning radius from the axis P1 is relatively small, so the material flow rate is relatively low. In addition, the degree of strain caused by shear deformation applied to the material is small as compared with the outer edge region 4p, and is in a neutral position or pseudo-neutral position with respect to shear. On the other hand, in the outer edge region 4p in the direction perpendicular to the axis in the pressurizing space 15 (the direction of the arrow X), the rotational radius from the axis P1 is relatively large. It is relatively larger than the obstacle region 43 on the center side. In this case, there is a possibility that the effect of refining the structure on the material is a cause of variation in the central region 4c and the outer edge region 4p.

  In this regard, according to the present embodiment, the obstacle member 4 is less pressurized in the central region 4c in the direction perpendicular to the axis P1 (the arrow X direction and the radial direction) of the machining space 10 because the structure refinement effect is small. A failure region 43 that is an obstacle to reduce the flow of material in the space 15 is provided. In the direction perpendicular to the axis (the direction of the arrow X), the material passage 40 is provided outside the obstacle region 43 of the obstacle member 4. The material facing the obstacle region 43 easily flows into the material passage 40 and is refined in the material passage 40.

  As a result, it is advantageous to reduce variation in strain due to shear deformation in the direction perpendicular to the axis of the pressurizing space 15 (arrow X direction). That is, the material portion to which only a small amount of strain is applied is eliminated from flowing into the pressure receiving space 16, and the variation in the miniaturization effect is reduced in the entire material.

  According to the present embodiment, the rotation speed and the total number of rotations of the obstruction member 4 are determined based on the composition of the material, the volume of the material loaded in the pressurized space 15, and the hard phase when the material has a hard phase. Although it selects suitably according to a material etc., 0.1-20 rpm, 0.3-10 rpm, 0.5-5 rpm is illustrated. However, it is not limited to these. In processing the material of the pressurized space 15, the total number of rotations is 2 to 100 times, 3 to 50 times, 5 to 20 times, and 7 to 12 times. However, it is not limited to these.

(Test example)
The test which refines | miniaturizes a test piece using the apparatus shown in FIG. 3 and FIG. 4 was implemented. The material of the test piece formed from the material before processing is a cast material of an aluminum-silicon alloy, and by mass ratio, Si is 16.4%, Cu is 2.9%, and Mg is 1.01%. Fe was 3.8%, Ti was less than 0.2%, and the balance was Al. The test piece before processing had a cylindrical shape with an outer diameter of 10 millimeters and a length of 15 millimeters, and the temperature was about 350 ° C. The outer diameters of the first base portion 11 and the second base portion 12 were 45 millimeters, and the inner diameters of the pressure space 15 and the pressure receiving space 16 were 10 millimeters, respectively. The axial length of the first base portion 11 and the second base portion 12 in the arrow Y1 direction was 50 millimeters. The material passage 40 has a circular shape, and the inner diameter of the material passage 40 is 3 millimeters. The driving force of the pressure member 2 in the forward direction (arrow Y1 direction) was 300 MPa. FIG. 6 shows an example of a photograph of the structure of the test example observed with a microscope. As shown in FIG. 6, the whole aluminum alloy was refined like the structure of FIG. In particular, although the cast material contains 16.4% of Si, coarse primary crystal silicon particles were not dispersed.

7 to 9 show Embodiment 3 of the present invention. The obstruction member 4 includes an inner member 44 and an outer member 45, and the inner member 44 includes a plurality (three) of material passage paths 40. The obstruction member 4 is continuously rotated around the axis P1 in the direction of the arrow R1. FIG. 9 shows a cross section taken along the line IX-IX in FIG. 8, that is, a cross section obtained by cutting the obstacle member 4 in the thickness direction thereof.

  As shown in FIG. 9, the material passage 40 includes a first passage portion 40f having a first hole core mf and a second passage portion 40s having a second hole core ms. The first hole core mf and the second hole core ms are inclined in different directions. The first passage portion 40f and the second passage portion 40s communicate with each other.

  Here, the direction of the arrow Ra indicates the direction in which the material in the pressurizing space 15 flows relative to the obstacle member 4. In this case, since the obstacle member 4 rotates together with the material passageway 40, the material passing through the material passageway 40 is subjected to distortion due to shear deformation, so that the material structure becomes fine. As shown in FIG. 9, since the inclination direction is different between the first hole core mf of the first passage portion 40f and the second hole core ms of the second passage portion 40s, the obstacle member 4 is rotated in the direction of the arrow R1. The strain due to shear deformation applied to the material is complicated and large, which is advantageous for making the material fine. Even when the material includes a hard phase, the hard phase can be effectively divided.

  As shown in FIG. 9, the first hole core mf on the pressurizing space 15 side is inclined so as to go in the direction opposite to the arrow Ra direction from the pressurizing space 15 toward the pressure receiving space 16. The second hole core ms on the pressure receiving space 16 side is inclined so as to go in the same direction as the arrow Ra direction from the pressurizing space 15 toward the pressure receiving space 16.

As shown in FIG. 10, the hole core mt of the material passage 40 is inclined in the direction opposite to the arrow Ra direction as it goes from the pressurizing space 15 to the pressure receiving space 16. In this case, distortion due to shear deformation is effectively applied to the material passing through the material passage 40.

As shown in FIG. 11, the hole core mu of the material passage 40 is inclined in the same direction as the direction of the arrow Ra as it goes from the pressurizing space 15 to the pressure receiving space 16. In this case, when the obstacle member 4 rotates, when the material passes through the material passage 40, the material is strained by shear deformation, so that the material structure becomes fine. This method is suitable when it is not desired to excessively increase the strain due to shear deformation applied to the material depending on the type of material.

(Embodiment 8)
FIG. 14 shows an eighth embodiment. This embodiment has basically the same configuration and the same function and effect as the first embodiment. According to the metal material refinement apparatus according to the present embodiment, as shown in FIG. 14, the base 1 is divided into two in the direction in which the shaft core P <b> 1 extends, and the cylindrical first that functions as a container is used. 1 base part 11 and the cylindrical 2nd base part 12 which functions as a container are provided. A drive source 5 for rotating the obstacle member 4 around the axis P1 of the machining space 10 is provided.

  The drive source 5 includes a first drive gear 51 as a drive member having a first drive tooth portion 51 a that meshes with a tooth portion 42 a formed on the ring portion 42 of the outer member 45 of the obstacle member 4, A second drive gear 53 as a drive member having a coaxial intermediate gear 52, a second drive tooth portion 53a meshing with the intermediate tooth portion 52a of the intermediate gear 52, and a drive source for rotating the second drive gear 53 And a drive motor 54.

  When the motor shaft 54c of the drive motor 54 is rotationally driven, the second drive gear 53 is rotationally driven, the intermediate gear 52 is rotated, and the first drive tooth portion 51a of the first drive gear 51 and the tooth portion 42a of the obstacle member 4 are rotated. The obstruction member 4 rotates around the axis P <b> 1 of the machining space 10. Thereby, as described above, the material in the processing space 10 can be miniaturized. The first drive gear 51, the intermediate gear 52, and the second drive gear 53 constitute a speed reduction mechanism. For this reason, the driving force of the drive motor 54 can be decelerated and transmitted to the obstruction member 4 as rotational power, and the torque force that rotates the obstruction member 4 about the axis P1 can be increased. Here, when the pitch circle diameter of the tooth portion 42a formed on the ring portion 42 of the outer member 45 of the obstacle member 4 is PD1, and the pitch circle diameter of the first drive gear 51 is PD2, PD1 <PD2. Thus, the torque force for rotating the obstacle member 4 around the axis P1 can be increased. Therefore, the material structure can be refined by effectively giving strain due to shear deformation to the material.

As shown in FIG. 15, the obstacle region 43 includes a material guide portion 43 x that is inclined so as to expand radially outward from the axis P <b> 1 as it goes in the forward direction (arrow Y <b> 1 direction) of the pressurizing body 2. . Since the material whose flow is restricted by the obstacle region 43 in the pressurizing space 15 can flow well toward the material passage 40 along the inclination of the material guide portion 43x, the flow resistance of the material is reduced. .

(Embodiment 10)
