Description

Technical Field

[0001] The following description relates to a method for repeatedly processing metal, and more specifically to a metal processing method in which metal in a hexahedral shape is repeatedly forged as a whole to be processed into a strict structure. Background Art

[0002] Generally speaking, the characteristics of metals vary depending on the state of their internal microstructures or aggregate structures. For example, as the microstructure becomes finer or the aggregate structure develops, the mechanical or physical properties of metal materials, such as strength, hardness, and durability, become better.

[0003] Therefore, the method of applying plastic deformation or additional heat treatment to metal materials to control the internal structure is one of the important processing methods in metal processing.

[0004] In addition, processing methods such as rolling, extrusion, and drawing will cause large plastic deformation and changes in shape inside the metal, so there are limitations on the shapes that can be achieved through other processes. In order to overcome the limitations on deformation, the ECAP (Equal Channel Angular Pressing) process can add plastic deformation without the size change of the test product, and can repeatedly add strong plastic deformation without the size change of the metal.

[0005] However, due to the characteristics of this process, a very high stress is required due to contact friction, and uniform deformation cannot be obtained at the beginning and end of the metal material, and the uneven parts at the beginning and end need to be removed. Therefore, there is a problem of large material loss as the process proceeds. Summary of the invention

[0006] An object of one embodiment is to provide a method for processing a metal to have a homogeneous ultra-fine microstructure.

[0007] Specifically, an embodiment aims to provide a metal processing method that solves the above-mentioned problems, and provides a metal processing method that minimizes the shape change of the metal's exterior by repeatedly processing the edges and corners of the hexahedral metal in three axial directions through diagonal forging and reset diagonal forging, adds uniform deformation inside the metal, and uniformly controls the fine structure and aggregate structure. The problems to be solved by the present invention are not limited to this.

[0008] A method for processing a hexahedral metal in one embodiment includes the following steps: an X-axis corner forging step, in which two X-axis corners formed in the X-axis direction and arranged on opposite surfaces based on the center of the hexahedral metal are pressurized to process the hexahedral metal into hexagonal pillar metal, and the hexagonal pillar metal is restored to the hexahedral metal again; a Y-axis corner forging step, in which two Y-axis corners formed in the Y-axis direction and arranged on opposite surfaces based on the center of the hexahedral metal are pressurized to process the hexahedral metal into hexagonal pillar metal, and the hexagonal pillar metal is restored to the hexahedral metal again; and a Z-axis corner forging step, in which two Z-axis corners formed in the Z-axis direction and arranged on opposite surfaces based on the center of the hexahedral metal are pressurized to process the hexahedral metal into hexagonal pillar metal, and the hexagonal pillar metal is restored to the hexahedral metal again, and the X-axis corner forging step, the Y-axis corner forging step and the Z-axis corner forging step are respectively performed twice.

[0009] The Y-axis corner forging step is performed after the X-axis corner forging step, and the Z-axis corner forging step is performed after the Y-axis corner forging step.

[0010] The X-axis corner forging step includes: a first X-axis corner forging step and a second X-axis corner forging step performed after the first X-axis corner forging step, wherein the first X-axis corner forging step and the second X-axis corner forging step respectively include: X-axis diagonal forging, pressurizing two X-axis corners formed in the X-axis direction and arranged on opposite surfaces based on the center of the hexahedral metal, so as to process the hexahedral metal into a hexagonal pillar metal; and an X-axis reset diagonal forging step, which is performed after the X-axis diagonal forging step, and restores the hexagonal pillar metal to a hexahedral metal again.

[0011] The two X-axis corners pressed in the X-axis diagonal forging step are flattened in the X-axis resetting diagonal forging step, respectively, and are arranged at the center of any one of the six faces constituting the hexahedral metal.

[0012] The two X-axis corners pressurized in the X-axis diagonal forging step of the first X-axis corner forging step constitute any one of the 12 corners forming the hexahedral metal after the X-axis restoring step of the second X-axis corner forging step.

[0013] The X-axis diagonal forging step is performed on a first die that accommodates any one of the edges formed in the X-axis direction and limits the deformation of the surface perpendicular to the edge formed in the X-axis direction. The X-axis reset diagonal forging step is performed on a side surface of the hexagonal pillar metal and limits the deformation of the surface perpendicular to the edge formed in the X-axis direction.

[0014] The Y-axis corner forging step includes a first Y-axis corner forging step and a second Y-axis corner forging step performed after the first Y-axis corner forging step, wherein the first Y-axis corner forging step and the second Y-axis corner forging step respectively include: Y-axis diagonal forging, pressurizing two Y-axis corners formed in the Y-axis direction and arranged on opposite surfaces based on the center of the hexahedral metal to process the hexahedral metal into hexagonal pillar metal; and Y-axis reset diagonal forging, which is performed after the Y-axis diagonal forging step and restores the hexagonal pillar metal to the hexahedral metal again.

[0015] The Z-axis corner forging step includes: a first Z-axis corner forging step and a second Z-axis corner forging step performed after the first Z-axis corner forging step, wherein the first Z-axis corner forging step and the second Z-axis corner forging step respectively include: Z-axis diagonal forging, pressurizing two Z-axis corners formed in the Z-axis direction and arranged on opposite surfaces based on the center of the hexahedral metal to process the hexahedral metal into hexagonal pillar metal; and Z-axis reset diagonal forging, which is performed after the Z-axis diagonal forging step and restores the hexagonal pillar metal to the hexahedral metal again.

[0016] According to a method for processing hexahedral metal in one embodiment, the shape change of the metal exterior is minimized by repeatedly performing diagonal forging and resetting diagonal forging, and uniform deformation is added inside the metal to uniformly control the fine structure and aggregate structure, thereby being able to manufacture particulate metal materials such as tantalum or copper. Of course, the scope of the present invention is not limited by this effect. The effect of the present invention is not limited to this. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 A sequence diagram showing a method for processing a hexahedral metal according to an embodiment.

[0037] Reference Figure 1 , a metal processing method of an embodiment includes: an X-axis corner forging step S1, a Y-axis corner forging step S2, and a Z-axis corner forging step S3. The X-axis corner forging step S1, the Y-axis corner forging step S2, and the Z-axis corner forging step S3 are respectively performed twice.

[0038] Here, the hexahedral metal as the processing object is Figure 3 and Figure 4As shown in the figure, it refers to a hexahedral metal 1 having a hexahedral shape as a whole, with four corners E11, E12, E13, and E14 formed in the X-axis direction, four corners E21, E22, E23, and E24 formed in the Y-axis direction, and four corners E31, E32, E33, and E34 formed in the Z-axis direction.

[0040] Figure 2 To show processing more specifically Figure 1 Sequential diagram of the method for hexahedral metals.

[0041] Reference Figure 2 , the X-axis corner forging step S1 consists of two times. The X-axis corner forging step S1 includes: a first X-axis corner forging step, and a second X-axis corner forging step performed after the first X-axis corner forging step.

The second X-axis corner forging step includes a second X-axis diagonal forging step S13 and a second X-axis reset diagonal forging step S14.

[0042] The first X-axis diagonal forging step S11 and the second X-axis diagonal forging step S13 are performed by the first die M1 (refer to Figure 5 ) is performed, the first X-axis reset diagonal forging step S12 and the second X-axis reset diagonal forging step S14 use the second die M2 (refer to Figure 7 )conduct.

[0043] The Y-axis corner forging step S2 is composed of two times. The Y-axis corner forging step S2 includes a first Y-axis corner forging step and a second Y-axis corner forging step performed after the first Y-axis corner forging step. The first Y-axis corner forging step includes a first Y-axis diagonal forging step S21 and a first Y-axis reset diagonal forging step S22. The second Y-axis corner forging step includes a second Y-axis diagonal forging step S23 and a second Y-axis reset diagonal forging step S24.

[0044] The first Y-axis diagonal forging step S21 and the second Y-axis diagonal forging step S23 are performed by the first die M1 (refer to Figure 5 ) is performed, the first Y-axis reset diagonal forging step S22 and the second Y-axis reset diagonal forging step S24 use the second die M2 (refer to Figure 7 )conduct.

[0045] The Z-axis corner forging step S3 is composed of two times. The Z-axis corner forging step S3 includes a first Z-axis corner forging step and a second Z-axis corner forging step performed after the first Z-axis corner forging step. The first Z-axis corner forging step includes a first Z-axis diagonal forging step S31 and a first Z-axis reset diagonal forging step S32. The second Z-axis corner forging step includes a second Z-axis diagonal forging step S33 and a second Z-axis reset diagonal forging step S34.

[0046] The first Z-axis diagonal forging step S31 and the second Z-axis diagonal forging step S33 are performed by the first die M1 (refer to Figure 5 ) is performed, the first Z-axis reset diagonal forging step S32 and the second Z-axis reset diagonal forging step S34 use the second die M2 (refer to Figure 7 )conduct.

[0047] Figure 3 To display in steps Figure 1 Conceptual diagram of a part of the metal processing steps of the metal processing method, Figure 4 To show the steps for Figure 3 , Figure 1 A conceptual diagram of the remaining steps of the metalworking method.

[0048] Reference Figure 3 and Figure 4 The first X-axis diagonal forging step S11 is a step of forging the hexagonal pillar metal 2 as a whole by pressurizing two of the edges E11, E12, E13, and E14 in the X-axis direction of the hexahedral metal 1 in the diagonal direction, as shown in the upper left picture. Here, the case of being arranged in the "diagonal direction" refers to the case of being arranged on opposite surfaces based on the center of the hexahedral metal 1. The first X-axis diagonal forging step S11 is performed using a first die M1 that limits the deformation of the first surface F1 perpendicular to the X-axis (refer to Figure 5 ). Therefore, since the deformation of the first surface F1 is restricted, when the corners E11 and E13 are pressurized, the second surface F2 and the third surface F3 perpendicular to the first surface F1 are guided to deform, and a protrusion formed by the second surface F2 and the third surface F3 is formed.

[0049] Here, the first X-axis reset diagonal forging step S12 refers to a step of rotating the hexagonal pillar metal 2 by 90 degrees as a whole, and pressurizing the protrusions of the remaining two corners E12 and E14 of the four corners E11, E12, E13, and E14 arranged in four four-axis directions, so as to restore the hexahedral metal 1 as a whole as shown in the fourth picture on the upper left. At this time, the first X-axis reset diagonal forging step S12 uses the second die M2 (refer to FIG. 2 ) that restricts the deformation of the first surface F1. Figure 7 ). Therefore, when the protrusion is pressurized by restricting the deformation of the first surface F1, the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0050] like Figure 3 As shown in the fourth picture on the upper left side, even though it is similar to the original shape, the internal fine structure is further refined, thereby improving the mechanical or material properties. However, in this step, all parts of the organization are not restored to their original positions. After the first X-axis reset diagonal forging step S12, the first edges E11 and E12 are flattened by squeezing the inside of the second face F2 perpendicular to the first face F1 of the forged hexahedral metal 1. In other words, the two edges E11 and E12 pressurized in the first X-axis diagonal forging step S11 are located in the center of one of the six faces constituting the hexahedral metal after the first X-axis reset diagonal forging step S12. That is, the organization is partially moved and not fully restored. Therefore, in order to fully restore the organization, the subsequent steps need to be performed.

[0051] The second X-axis diagonal forging step S13 is a step of forging the hexagonal metal 2 as a whole by pressing two corners E15, E17 arranged in the diagonal direction among the corners E15, E16, E17, and E18 in the X-axis direction, as shown in the first picture on the upper middle side. The second X-axis diagonal forging step S13 is performed using the first die M1 that restricts the deformation of the first surface F1 perpendicular to the X-axis (see Figure 5 ). Therefore, since the deformation of the first surface F1 is restricted, when the corners E15 and E17 are pressed, the second surface F2 and the third surface F3 perpendicular to the first surface F1 are guided to deform, thereby forming a protrusion formed by the second surface F2 and the third surface F3.

[0052] Furthermore, the second X-axis reset diagonal forging step S14 refers to Figure 3As shown in the third picture on the upper middle side, the hexagonal pillar metal 2 is rotated 90 degrees relative to the original metal 2, and the protrusions of the remaining two corners E16 and E18 are pressurized, as shown in the fourth picture on the upper middle side, to restore the hexahedral metal 1 as a whole. At this time, the second X-axis reset diagonal forging step S14 uses the second die M2 (refer to FIG. 1 ) which restricts the deformation of the first surface F1. Figure 7 ). Therefore, since the deformation of the first surface F1 is restricted, when the protrusion is pressurized, the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0053] After the second X-axis resetting diagonal forging step S14, the hexahedral metal Figure 3 As shown in the fourth picture on the upper middle side, it has a shape similar to the original shape, and the fine tissues inside are further miniaturized. While improving the mechanical and physical properties, it completely restores the original positions of all parts of the tissue, minimizes the deformation rate and prevents tissue damage.

[0054] Through the above steps, the X-axis corner forging step S1 for limiting the deformation of the first surface F1 perpendicular to the X-axis is completed.

[0055] Furthermore, the first Y-axis diagonal forging step S21 is a step of forging the hexagonal metal 2 as a whole by pressing two diagonally arranged edges E21, E22, E23, and E24 of the hexahedral metal 1 in the Y-axis direction as shown in the second picture on the upper right side. The first Y-axis diagonal forging step S21 is performed using the first die M1 that restricts the deformation of the second surface F2 perpendicular to the Y axis (see Figure 5 ). Therefore, since the deformation of the second surface F2 is restricted, when the corners E21 and E23 are pressurized, the first surface F1 and the third surface F3 perpendicular to the second surface F2 are guided to deform, thereby forming a protrusion formed by the first surface F1 and the third surface F3.

[0056] Furthermore, the first Y-axis reset diagonal forging step S22 refers to a step of rotating the hexagonal pillar metal 2 by 90 degrees as a whole, and applying pressure to the protrusions of the remaining two corners E22 and E24 of the four four-axis directions of the corners E21, E22, E23, and E24, as shown in the fourth picture on the upper left, to restore the hexahedral metal 1 as a whole. After the first Y-axis diagonal forging step S21, the two corners E22 and E24 are respectively located in the central part of one side surface rather than the corners of the hexagonal pillar metal 2. At this time, the first Y-axis reset diagonal forging step S22 uses the second die M2 (refer to Figure 7). Therefore, since the deformation of the second surface F2 is restricted, when the protrusion is pressurized, the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0057] like Figure 3 As shown in the fourth picture on the upper right side, even if the shape is similar to the original shape, the internal fine structure is further miniaturized, thereby improving the mechanical or material properties. However, this step is to restore all parts of the organization to the original position. In other words, the two corners E21 and E22 pressed in the first Y-axis diagonal forging step S21 are located in the center of one of the six faces constituting the hexahedral metal after the first Y-axis reset diagonal forging step S22. That is, the tissue part moves and is not fully restored. Therefore, in order to prevent the complete recovery of, it is necessary to perform the following steps.

[0058] Furthermore, if Figure 4 As shown in the figure, the second Y-axis diagonal forging step S23 is a step of forging the hexagonal pillar metal 2 as a whole by pressurizing the two diagonally arranged edges E25, E26, E27, and E28 of the hexahedral metal 1 in the Y-axis direction as shown in the first picture on the upper left side. The second Y-axis diagonal forging step S23 is performed using the first die M1 that restricts the deformation of the second surface F2 perpendicular to the Y axis (refer to Figure 5 ). Therefore, since the deformation of the second surface F2 is restricted, when the corners E25 and E27 are pressurized, the first surface F1 and the third surface F3 perpendicular to the second surface F2 are guided to deform, forming a protrusion formed by the first surface F1 and the third surface F3.

[0059] Furthermore, the second Y-axis reset diagonal forging step S24 refers to Figure 4 As shown in the third picture on the upper left side, the hexagonal pillar metal 2 is rotated 90 degrees relative to the whole, and the protrusions of the remaining two corners E26 and E28 of the four four-axis directions of the corners E25, E26, E27, and E28 are pressurized, as shown in FIG. Figure 4 As shown in the fourth picture on the upper left side of the figure, the whole is restored to the step of the hexahedral metal 1. At this time, the second Y-axis reset diagonal forging step S24 uses the second die M2 (refer to Figure 7 ). Therefore, the deformation of the second surface F2 is restricted, and when the protrusion is pressurized, the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0060] After the second Y-axis resetting diagonal forging step S24, the hexahedral metal Figure 4As shown in the fourth picture on the upper left side, it has a shape similar to the original shape, and the internal fine tissues are further miniaturized, thereby improving the mechanical and physical properties. At the same time, all parts of the tissue are completely restored to their original positions, thereby minimizing the deformation rate and preventing tissue damage.

[0061] Through the above steps, the Y-axis corner forging step S2 of limiting the deformation of the second surface F2 perpendicular to the Y-axis of the initial hexahedral metal is completed.

[0062] Furthermore, the first Z-axis diagonal forging step S31 refers to Figure 4 As shown in the upper middle picture, two corners E31 and E33 arranged in the diagonal direction among the corners E31, E32, E33, and E34 of the hexahedral metal 1 in the Z-axis direction are pressurized, such as Figure 4 As shown in the second picture on the middle upper side, the whole is forged into a hexagonal pillar metal 2. The first Z-axis diagonal forging step S31 is performed using the first die M1 that limits the deformation of the third surface F3 perpendicular to the Z axis (refer to Figure 5 ). Therefore, since the deformation of the third surface F3 is restricted, when the corners E31 and E33 are pressurized, the first surface F1 and the second surface F2 perpendicular to the third surface F3 are guided to deform, thereby forming a protrusion formed by the first surface F1 and the second surface F2.

[0063] Furthermore, the first Z-axis reset diagonal forging step S32 refers to Figure 4 As shown in the third picture on the middle upper side, the hexagonal pillar metal 2 is rotated 90 degrees relative to the whole, and the protrusions of the remaining two corners E32 and E34 of the four four-axis directions of the corners E31, E32, E33, and E34 are pressurized, as shown in FIG. Figure 4 As shown in the fourth picture on the middle upper side, the whole is restored to the hexahedral metal 1. After the first Z-axis diagonal forging step S31, the two corners E32 and E34 are respectively located in the center of one side, not the corners of the hexagonal pillar metal 2. At this time, the first Z-axis reset diagonal forging step S32 uses the second die M2 (refer to Figure 7 ). Therefore, since the deformation of the third surface F3 is restricted, when the protrusion is pressurized, the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0064] like Figure 4As shown in the fourth picture on the middle upper side, even though it is similar to the original shape, the internal fine tissue is more refined, thereby improving the mechanical or material properties. However, this step does not restore all parts of the tissue to their original positions. In other words, the two corners E31 and E32 pressurized in the first Z-axis diagonal forging step S31 are located in the center of one of the six faces constituting the hexahedral metal after the first Z-axis reset diagonal forging step S32. That is, the tissue partially moves and is not fully restored. Therefore, in order to fully restore the tissue, the subsequent steps need to be performed.

[0065] Furthermore, if Figure 4 As shown in the figure, the second Z-axis diagonal forging step S33 is a step of applying pressure to two corners E35, E37 arranged in the diagonal direction among the corners E35, E36, E37, and E38 in the Z-axis direction of the hexahedral metal 1, and forging the whole into a hexagonal pillar metal 2 as shown in the second picture on the upper middle side. The second Z-axis diagonal forging step S33 is performed using the first die M1 that restricts the deformation of the third surface F3 perpendicular to the Y axis (refer to Figure 5 ). Therefore, since the deformation of the third surface F3 is restricted, when the corners E35 and E37 are pressurized, the first surface F1 and the second surface F2 perpendicular to the third surface F3 are guided to deform, thereby forming a protrusion formed by the first surface F1 and the second surface F2.

[0066] Furthermore, the second Z-axis reset diagonal forging step S34 refers to Figure 4 As shown in the third picture on the upper right side, the hexagonal pillar metal 2 is rotated 90 degrees relative to the whole, and the protrusions of the remaining two corners E36 and E38 of the four four-axis directions of the corners E35, E36, E37, and E38 are pressurized, as shown in FIG. Figure 4 As shown in the fourth picture on the upper right side of the figure, the whole is restored to the step of hexahedral metal 1. At this time, the second Z-axis reset diagonal forging step S34 uses the second die M2 (refer to Figure 7 ). Therefore, since the deformation of the third surface F3 is restricted, when the protrusion is pressurized, the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0067] After the second Z-axis reset diagonal forging step S34, the hexahedral metal Figure 4 As shown in the fourth picture on the upper right side, it has a shape similar to the original shape, and the internal fine tissues are further miniaturized, thereby improving the mechanical and physical properties. At the same time, all parts of the tissue are completely restored to their original positions, thereby minimizing the deformation rate and preventing tissue damage.

[0068] Through the above steps, the Z-axis corner forging step S3 of limiting the deformation of the third surface F3 perpendicular to the Z axis of the initial hexahedral metal is completed.

[0069] Therefore, after the X-axis edge forging step S1, the Y-axis edge forging step S2 and the Z-axis edge forging step S3, the hexahedral metal minimizes the external shape change and adds uniform deformation inside the metal, uniformly controlling the fine structure and aggregate structure, thereby enabling the manufacture of particulate metal materials such as tantalum or copper.

[0070] Figure 5 This is a perspective view showing a state before X-axis diagonal forging of a first die of a metal processing method according to an embodiment. Figure 6 The invention is a three-dimensional view showing a state of a first die after X-axis diagonal forging applicable to a metal processing method according to an embodiment.

[0071] Reference Figure 5 and Figure 6 The first mold M1 includes: a receiving fixture 10, including a receiving portion A having two opposite inner side surfaces to limit the deformation of the surface in any direction; a lower portion 20, formed at the lower portion of the receiving portion A, forming a first concave inclined surface C1 and a second concave inclined surface C2 that are symmetrical based on the portion in contact with the hexahedral metal 1; an upper portion 30, sliding in a direction of inserting into the lower portion 20 or in a direction away from the lower portion 20, and forming a third concave inclined surface C3 and a fourth concave inclined surface C4 that are symmetrical based on the portion in contact with the hexahedral metal 1.

[0072] In the case of using the first die M1, in the X-axis diagonal forging step, the Y-axis diagonal forging step, and the Z-axis diagonal forging step, the hexahedral metal 1 is placed in the receiving portion A so that the corners are in contact with the lower portion 20, and then the hexahedral metal 1 is mounted on the lower portion 20. Figure 6 As shown, the hexahedral metal 1 is pressed by the upper portion 30 to be processed into the hexagonal pillar metal 2. Thus, the first die M1 is used to perform diagonal forging, which minimizes the deformation of the structure and refines the structure.

[0073] Figure 7 This is a perspective view showing a state of the second die before X-axis reset diagonal forging applicable to a metal processing method of an embodiment. Figure 8 The present invention is a three-dimensional view showing a state of a second die after X-axis resetting diagonal forging applicable to a metal processing method according to an embodiment.

[0075] In the case of using the second die M2, in the X-axis reset diagonal forging step, the Y-axis reset diagonal forging step, and the Z-axis reset diagonal forging step, the hexagonal pillar metal 2 is put into the receiving portion B and installed in the lower part 50, and then the hexagonal pillar metal 2 is pressurized by the upper part 60 to be restored to the hexahedral metal 1. The reset diagonal forging is performed by the second die M2, and the reset diagonal forging minimizes the deformation of the structure and makes the structure finer.

[0076] Fig. 9 A sequence diagram showing a method for processing metal according to an embodiment.

[0077] Reference Fig. 9 , a metal processing method of an embodiment includes an X-axis corner forging step, a Y-axis corner forging step, and a Z-axis corner forging step. The X-axis corner forging step, the Y-axis corner forging step, and the Z-axis corner forging step are respectively performed twice. The X-axis corner forging step, the Y-axis corner forging step, and the Z-axis corner forging step are performed in two cycles. In other words, after the X-axis corner forging step S1-1, the Y-axis corner forging step S2-1, and the Z-axis corner forging step S3-1 are performed once in sequence, then the X-axis corner forging step S1-2, the Y-axis corner forging step S2-2, and the Z-axis corner forging step S3-2 are performed again.

[0078] Here, the hexahedral metal as the processing object is Figure 3 and Figure 4 As shown in the figure, it refers to a hexahedral metal 1 having a hexahedral shape with four corners E11, E12, E13, and E14 formed in the X-axis direction, four corners E21, E22, E23, and E24 formed in the Y-axis direction, and four corners E31, E32, E33, and E34 formed in the Z-axis direction.

For example, the hexahedral metal 1 is made of tantalum or copper.

The Y-axis corner forging step refers to a step of pressurizing the four corners E21, E22, E23, and E24 formed in the Y-axis direction of the hexahedral metal 1. The Z-axis corner forging step refers to a step of pressurizing the four corners E31, E32, E33, and E34 formed in the Z-axis direction of the hexahedral metal 1.

[0082] The first X-axis diagonal forging step S11 and the second X-axis diagonal forging step S13 are performed by the first die M1 (refer to Figure 5 ) is performed, the first X-axis reset diagonal forging step S12 and the second X-axis reset diagonal forging step S14 use the second die M2 (refer to Figure 7 )conduct.

[0083] The Y-axis corner forging step includes a first Y-axis corner forging step S2-1 and a second Y-axis corner forging step S2-2. The first Y-axis corner forging step S2-1 includes a first Y-axis diagonal forging step S21 and a first Y-axis reset diagonal forging step S22, and the second Y-axis corner forging step S2-2 includes a second Y-axis diagonal forging step S23 and a second Y-axis reset diagonal forging step S24.

[0084] The first Y-axis diagonal forging step S21 and the second Y-axis diagonal forging step S23 are performed by the first die M1 (refer to Figure 5 ) is performed, the first Y-axis reset diagonal forging step S22 and the second Y-axis reset diagonal forging step S24 use the second die M2 (refer to Figure 7 )conduct.

[0085] The Z-axis corner forging step S3 includes a first Z-axis corner forging step S3-1 and a second Z-axis corner forging step S3-2. The first Z-axis corner forging step S3-1 includes a first Z-axis diagonal forging step S31 and a first Z-axis reset diagonal forging step S32, and the second Z-axis corner forging step S3-2 includes a second Z-axis diagonal forging step S33 and a second Z-axis reset diagonal forging step S34.

[0086] The first Z-axis diagonal forging step S31 and the second Z-axis diagonal forging step S33 are performed by the first die M1 (refer to Figure 5 ) is performed, the first Z-axis reset diagonal forging step S32 and the second Z-axis reset diagonal forging step S34 use the second die M2 (refer to Figure 7 )conduct.

[0087] Fig.11 To display in steps Fig. 9 Conceptual diagram of a part of the metal processing steps of the metal processing method, Fig.12 Display in steps Fig.11 In Fig. 9 A conceptual diagram of the remaining steps of the metalworking method.

[0088] Fig.11 and Fig.12 In the case where the pattern does not exist, the drawings shown are for convenience of explanation, and the display in the case where the pattern does not exist does not necessarily mean the same surface. For example, the surfaces displayed in the case where the pattern does not exist in step S11 and step S12 are the same surface, but the surfaces displayed in the case where the pattern does not exist in step S12 and step S13 are different surfaces.

[0089] Reference Fig.11 and Fig.12 The first X-axis diagonal forging step S11 is a step of forging the hexagonal pillar metal 2 as a whole by pressurizing two edges E11, E13 arranged in the diagonal direction among the edges E11, E12, E13, and E14 in the X1-axis direction of the hexahedral metal 1 as shown in the second picture from the upper left. Here, the case of being arranged in the "diagonal direction" refers to being arranged on opposite surfaces based on the center of the hexahedral metal 1. The first X-axis diagonal forging step S11 is performed using a first die M1 that limits the deformation of the first surface F1 perpendicular to the X1 axis (refer to Figure 5 ). Therefore, since the deformation of the first surface F1 is restricted, when the corners E11 and E13 are pressurized, the second surface F2 and the third surface F3 perpendicular to the first surface F1 are guided to deform, forming a protrusion formed by the second surface F2 and the third surface F3.

[0090] Furthermore, the first X-axis reset diagonal forging step S12 is a step of rotating the hexagonal pillar metal 2 by 90 degrees as a whole, and applying pressure to the protrusions of the remaining two corners E12 and E14 of the four corners E11, E12, E13, and E14 arranged in four four-axis directions, so as to restore the hexahedral metal 1 as a whole as shown in the fourth picture on the upper left side. At this time, the first X-axis reset diagonal forging step S12 uses the second die M2 (refer to Figure 7 ). Therefore, since the deformation of the first surface F1 is restricted, when the protrusion is pressurized, the hexahedral metal 1 is restored to a shape similar to the original shape as a whole.

[0091] like Fig.11 As shown in the fourth picture on the upper left side, even though it is similar to the initial shape, the internal fine structure is further refined, thereby improving the mechanical or material properties. However, all parts of the structure of this step are not restored to the initial position. After the first X-axis reset diagonal forging step S12, the remaining initial corners E11 and E12 are squeezed inside the second face F2 perpendicular to the first face F1 of the forged hexahedral metal 1 and flattened. In other words, the two corners E11 and E12 pressed in the first X-axis diagonal forging step S11 are located in the center of one of the six faces constituting the hexahedral metal after the first X-axis reset diagonal forging step S12.

[0092] The first Y-axis diagonal forging step S21 is as follows Fig.11 As shown in the first picture in the middle, two edges E21 and E23 arranged in the diagonal direction among the edges E21, E22, E23, and E24 in the Y1-axis direction of the hexahedral metal 1 are pressurized, such as Fig.11 The second picture from the middle upper side shows the step of forging the whole into a hexagonal pillar metal 2. The first Y-axis diagonal forging step S21 is performed using the first die M1 that restricts the deformation of the second surface F2' perpendicular to the Y1 axis (see Figure 5 ). Therefore, since the deformation of the second surface F2' is restricted, when the corners E21 and E23 are pressed, they are guided to deform toward the first surface and the third surface F3' perpendicular to the second surface F2', forming a protrusion formed by the first surface and the third surface F3'.

[0093] Furthermore, the first Y-axis reset diagonal forging step S24 refers to Fig.11 As shown in the third picture on the upper middle side, the hexagonal pillar metal 2 is rotated 90 degrees relative to the outside, and the protrusions of the remaining two corners E26 and E28 of the corners E21, E22, E23, and E24 arranged in the four axial directions are pressurized, and as shown in the fourth picture on the upper middle side, the whole is restored to the hexahedral metal 1. At this time, the first Y-axis reset diagonal forging step S24 uses the second die M2 (refer to Figure 7 ). Therefore, since the deformation of the second surface F2' is restricted, when the protrusion is pressurized, the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0094] After the first Y-axis resetting diagonal forging step S24, the hexahedral metal Fig.11 As shown in the fourth picture on the upper middle side, it has a shape similar to the original shape, and the internal fine tissues are smaller, improving the mechanical and physical properties, while minimizing the deformation rate, thereby preventing tissue damage.

[0095] Furthermore, the first Z-axis diagonal forging step S31 refers to Fig.11 As shown in the upper rightmost picture, two corners E31 and E33 arranged in the diagonal direction among the corners E31, E32, E33, and E34 of the hexahedral metal 1 in the Z1 axis direction are pressurized, such as Fig.11 As shown in the second picture on the upper right side, the whole is forged into a hexagonal pillar metal 2. The first Z-axis diagonal forging step S31 is performed using the first die M1 that limits the deformation of the third surface F3" perpendicular to the Z1 axis (refer to Figure 5 ). Therefore, due to the limitation of the deformation of the third surface F3", when the corners E31 and E33 are pressurized, the first surface F1" and the second surface perpendicular to the third surface F3" are guided to deform, forming a protrusion composed of the first surface F1" and the second surface.

[0096] Furthermore, the first Z-axis reset diagonal forging step S32 refers to Fig.11 As shown in the third picture on the upper right side, the hexagonal pillar metal 2 is rotated 90 degrees relative to the original metal 2, and the protrusions of the remaining two corners E32 and E34 of the four four-axis directions are pressurized to restore the hexahedral metal 1 as a whole. At this time, the first Z-axis reset diagonal forging step S32 uses the second mold M2 (refer to 7) that limits the deformation of the third surface F3". Therefore, due to the limitation of the deformation of the third surface F3", when the protrusion is pressurized, the hexahedral metal 1 as a whole is restored to a shape similar to the original shape.

[0097] like Fig.11 As shown in the fourth picture on the upper right, even though the shape is similar to the original, the internal fine structures are further miniaturized, thereby improving the mechanical and material properties.

[0098] Furthermore, if Fig.12As shown in the display, the second X-axis diagonal forging step S13 refers to a step of forging the hexagonal metal 2 as a whole by pressurizing two diagonally arranged edges E15, E16, E17, and E18 of the hexahedral metal 1 in the X2-axis direction, as shown in the first picture on the upper left side, as shown in the second picture on the upper middle side. The X2 axis refers to an axis different from the X1 axis. The second X-axis diagonal forging step S13 is performed using a first die M1 that limits the deformation of the first surface f1 perpendicular to the X-axis (refer to Figure 5 ). Therefore, since the deformation of the first surface f1 is restricted, when the corners E15 and E17 are pressed, the second surface f2 and the third surface f3 perpendicular to the first surface f1 are guided to deform, thereby forming a protrusion formed by the second surface f2 and the third surface f3.

[0099] Furthermore, the second X-axis reset diagonal forging step S14 refers to Fig.12 As shown in the third picture on the upper left side, the hexagonal pillar metal 2 is rotated 90 degrees relative to the whole, and the protrusions of the remaining two corners E16 and E18 of the four four-axis corners E15, E16, E17, and E18 are pressurized, as shown in FIG. Fig.12 As shown in the fourth picture on the upper left side of the figure, the whole is restored to the step of the hexahedral metal 1. At this time, the second X-axis reset diagonal forging step S14 uses the second die M2 (refer to Figure 7 ). Therefore, since the deformation of the first surface F1 is restricted, when the protrusion is pressurized, the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0100] After the second X-axis resetting diagonal forging step S14, the hexahedral metal Fig.12 As shown in the fourth picture on the upper left side, it has a shape similar to the original shape, and the internal fine structure is further miniaturized, thereby improving the mechanical and physical properties.

[0101] Furthermore, the second Y-axis diagonal forging step S23 refers to Fig.12 As shown in the uppermost middle picture, two corners E25 and E27 arranged in the diagonal direction among the corners E25, E26, E27, and E28 of the hexahedral metal 1 in the Y2-axis direction are pressurized, such as Fig.12 As shown in the second picture on the middle upper side, the whole is forged into a hexagonal pillar metal 2. Here, the Y2 axis is an axis different from the Y1 axis. The second Y-axis diagonal forging step S23 is performed using the first die M1 that limits the deformation of the second surface f2' perpendicular to the Y2 axis (refer to Figure 5). Therefore, since the deformation of the second surface f2' is restricted, when the corners E25 and E27 are pressurized, the first surface and the third surface f3' perpendicular to the second surface f2' are guided to deform, thereby forming a protrusion composed of the first surface and the third surface f3'.

[0102] Furthermore, the second Y-axis reset diagonal forging step S24 refers to Fig.12 As shown in the third picture on the upper middle side, the hexagonal pillar metal 2 is rotated 90 degrees relative to the whole, and the protrusions of the remaining two corners E26 and E28 of the four corners E25, E26, E27, and E28 in the Y2-axis direction are pressurized, as shown in FIG. Fig.12 As shown in the fourth picture on the middle upper side, the whole is restored to the hexahedral metal 1. After the second Y-axis diagonal forging step S24, the two corners E26 and E28 are respectively located in the central part of one side, rather than the corners of the hexagonal pillar metal 2. At this time, the second Y-axis reset diagonal forging step S24 uses the second die M2 (refer to Figure 7 ). Therefore, since the deformation of the second surface f2' is restricted, when the protrusion is pressurized, the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0103] like Fig.12 As shown in the fourth picture on the upper middle side, although the shape is similar to the original one, the internal fine structures are further miniaturized, thereby improving the mechanical and material properties.

[0104] Furthermore, if Fig.12 As shown in the figure, the second Z-axis diagonal forging step S33 refers to a step of forging the hexagonal pillar metal 2 as a whole by pressurizing two diagonally arranged edges E35, E36, E37, and E38 of the hexahedral metal 1 in the Z2-axis direction, as shown in the first picture on the upper right side, using the first die M1 that restricts the deformation of the third surface f3" perpendicular to the Y axis (see Figure 5 ). Therefore, due to the limitation of the deformation of the third surface f3", when the corners E35 and E37 are pressurized, the first surface f1" and the second surface perpendicular to the third surface f3" are guided to deform, forming a protrusion composed of the first surface f1" and the second surface.

[0105] Furthermore, the second Z-axis reset diagonal forging step S34 refers to Fig.12 As shown in the third picture on the upper right side, the hexagonal pillar metal 2 is rotated 90 degrees relative to the whole, and the protrusions of the remaining two corners E36 and E38 of the four four-axis corners E35, E36, E37, and E38 are pressurized, as shown in FIG. Fig.12As shown in the fourth picture on the upper right side, the whole is restored to the step of hexahedral metal 1. At this time, the second Z-axis reset diagonal forging step S34 uses the second die M2 (refer to Figure 7 ). Therefore, when the protruding portion is pressurized due to the restriction of the deformation of the third surface f3", the hexahedral metal 1 as a whole returns to a shape similar to the original shape.

[0106] After the second Z-axis reset diagonal forging step S34, the hexahedral metal Fig.12 As shown in the fourth picture on the upper right side, it has a shape similar to the original shape, and the internal fine structure is further miniaturized to improve the mechanical and physical properties.

[0107] Through the above steps, the Z-axis corner forging step S3 of limiting the deformation of the third face f3" perpendicular to the Z2 axis of the initial hexahedral metal is completed. Here, the Z2 axis refers to an axis different from the Z1 axis.

[0108] Therefore, the hexahedral metal minimizes the external shape change and adds uniform deformation inside the metal, uniformly controlling the fine structure and aggregate structure, thereby manufacturing ultra-fine grain metal materials such as tantalum or copper.

[0109] In summary, even if the embodiments are described by limited drawings, ordinary technicians in the corresponding technical field can apply various technical modifications and variations based on the above. For example, the described technology is executed in a different order from the described method, and / or the described system, structure, device, circuit and other components are combined or combined in a different form from the described method, or symmetrically or replaced by other components or equivalents, and appropriate results can also be achieved.
