Description

Technical Field

[0001] The utility model relates to the technical field of magnetic ring production, in particular to a magnetic ring mold. Background Art

[0002] Magnetic rings are essential components in the electrical and electronic fields, with crucial applications in low-voltage electrical equipment, electromagnetic shielding, and anti-electromagnetic interference. Special-shaped magnetic rings, as a crucial component, hold an irreplaceable position in certain specific areas. Nanocrystalline magnetic rings are typically produced by winding extremely thin nanocrystalline amorphous ribbon into a shape, followed by heat treatment using a specialized process to achieve specific performance. While common annular magnetic rings can be directly heat-treated, special-shaped magnetic rings, such as rectangular or racetrack-shaped ones, require molds to secure them before heat treatment to achieve their desired shape.

[0003] The magnetic ring molds in the existing technology have a single size and poor compatibility. One magnetic ring mold can only assemble a magnetic ring of a specific size. If the size of the magnetic ring changes, the mold needs to be re-made, which also increases the production and processing costs. Utility Model Content

[0060] This embodiment provides a magnetic ring mold. Figures 1 to 7 As shown, the magnetic ring mold is used to fix the magnetic ring 9. Specifically, the magnetic ring 9 includes two first ring parts 92 arranged opposite to each other and two second ring parts 91 arranged opposite to each other.

[0061] For the racetrack magnetic ring 9, the two first ring parts 92 are set to be semicircular arcs, and the two second ring parts 91 are set to be straight lines. For the rectangular magnetic ring 9, the two first ring parts 92 are set to be straight lines, and the two second ring parts 91 are also set to be straight lines. For example, Figure 6 The magnetic ring 9 shown in FIG. 1 is a racetrack-shaped magnetic ring 9 , and its first ring portion 92 is configured as a circular arc segment. Figure 7 The magnetic ring 9 shown in FIG. 1 is a rectangular magnetic ring 9 , and the first ring portion 92 thereof is configured as a straight line segment.

[0062] In this embodiment, the magnetic ring mold includes a first outer limiter 1, a second outer limiter 2, a first inner limiter 3, a second inner limiter 4, a first adjustment mechanism 51, and a second adjustment mechanism 52. The first outer limiter 1 and the second outer limiter 2 are arranged opposite to each other, and the first inner limiter 3 and the second inner limiter 4 are arranged opposite to each other. The first inner limiter 3 and the second inner limiter 4 are located between the first outer limiter 1 and the second outer limiter 2. The first adjustment mechanism 51 includes a first abutting portion and a first pressing portion. One end of the first abutting portion abuts against the outer side of the first outer limiter 1, and the other end of the first abutting portion passes through the first outer limiter 1 and the second outer limiter 2 and is movably connected to the first pressing portion on the outer side of the second outer limiter 2, so that the first outer limiter 1 and the second outer limiter 2 abut against the outer side of the magnetic ring 9 along the first direction. The second adjustment mechanism 52 is connected to the first inner limiter 3 and the second inner limiter 4 and is used to adjust the distance between the first inner limiter 3 and the second inner limiter 4 so that the first inner limiter 3 and the second inner limiter 4 abut against the inner side of the magnetic ring 9 along the first direction.

[0063] For example, direction a in the drawings indicates a first direction, which is the spacing direction between the first outer stopper 1 and the second outer stopper 2, and between the first inner stopper 3 and the second inner stopper 4, and is also the width direction of the magnetic ring 9 when the magnetic ring 9 is fixed. Direction b in the drawings indicates a second direction, which is the extension direction of the first outer stopper 1, the second outer stopper 2, the first inner stopper 3, and the second inner stopper 4, and is also the length direction of the magnetic ring 9 when the magnetic ring 9 is fixed.

[0064] In this embodiment, by adjusting the distance between the first abutting portion and the first pressing portion in the first adjustment mechanism 51, the first abutting portion and the first pressing portion press against the first outer limiting member 1 and the second outer limiting member 2 at different distances along the first direction, so that the first outer limiting member 1 and the second outer limiting member 2 respectively abut against the two outer sides of the magnetic ring 9, thereby adapting to magnetic rings 9 of different widths and ensuring that the outer side of the magnetic ring 9 is fixed in the first direction. By adjusting the distance between the first inner limiting member 3 and the second inner limiting member 4 through the second adjustment mechanism 52, the first inner limiting member 3 and the second inner limiting member 4 respectively abut against the two inner sides of the magnetic ring 9, thereby adapting to magnetic rings of different thicknesses and ensuring that the inner side of the magnetic ring 9 is fixed in the first direction. This makes it possible to adapt to magnetic rings 9 of different sizes and specifications, and has a simple structure, strong practicality and compatibility.

[0065] Specifically, the first contact portion and the first pressing portion press the first outer limiting member 1 and the second outer limiting member 2 along the first direction, so that the first outer limiting member 1 and the second outer limiting member 2 respectively abut against the outer sides of the two second ring portions 91 of the magnetic ring 9. The second adjustment mechanism 52 adjusts the distance between the first inner limiting member 3 and the second inner limiting member 4, so that the first inner limiting member 3 and the second inner limiting member 4 respectively abut against the inner sides of the two second ring portions 91 of the magnetic ring 9.

[0066] In addition, no spring is required in the mold. Even if the magnetic ring 9 is subsequently subjected to high-temperature treatment, the spring elasticity will not be deactivated and will not need to be replaced, further reducing the cost of use.

[0067] In this embodiment, the first abutting portion includes a first screw 511, the first pressing portion includes a first locking nut 512, the first outer limiting member 1 is provided with a first through-hole 11, and the second outer limiting member 2 is correspondingly provided with a second through-hole 21. The first screw 511 penetrates the first through-hole 11 and the second through-hole 21 and is threadedly connected to the first locking nut 512. Specifically, the first screw 511 penetrates the first outer limiting member 1 and the second outer limiting member 2 respectively, and the first locking nut 512 is threadedly connected thereto. By screwing the first locking nut 512, the distance between the first locking nut 512 and the screw head of the first screw 511 can be adjusted, thereby adjusting the distance between the first outer limiting member 1 and the second outer limiting member 2, thereby adapting to magnetic rings 9 of different widths.

[0068] Furthermore, the first inner limit member 3 is provided with a third through hole 31 , the second inner limit member 4 is provided with a fourth through hole 41 , and the first screw 511 passes through the first through hole 11 , the third through hole 31 , the fourth through hole 41 and the second through hole 21 and is threadedly connected to the first locking nut 512 .

[0069] Specifically, in the process of penetrating the first outer limit member 1 and the second outer limit member 2, the first screw 511 also penetrates the first inner limit member 3 and the second inner limit member 4, thereby connecting the first outer limit member 1, the second outer limit member 2, the first inner limit member 3 and the second inner limit member 4 to ensure that the entire mold structure is reliable and stable.

[0070] Exemplarily, the first screw 511 , the first through-hole 11 , the second through-hole 21 , the third through-hole 31 , and the fourth through-hole 41 are provided in a one-to-one correspondence.

[0071] For example, the diameter of the first through-hole 11 and the second through-hole 21 is preferably set to 4.93 mm. The diameter of the third through-hole 31 and the fourth through-hole 41 is preferably set to 5 mm. The first screw 511 is preferably set to an M5 screw.

[0072] In some other optional embodiments, the first adjustment mechanism 51 can also be configured as a telescopic cylinder, an electric push rod, a linear servo module, etc. Taking the case where the first adjustment mechanism 51 is configured as an electric push rod as an example, the electric push rod (not shown) is located between the first outer limit member 1 and the second outer limit member 2. The electric push rod includes a fixed portion and a telescopic portion, one of which is connected to the first outer limit member 1, and the other is connected to the second outer limit member 2. The telescopic portion is telescopic relative to the fixed portion, and can drive the first outer limit member 1 and the second outer limit member 2 to move closer to or farther from each other along the first direction, thereby adjusting the distance between the first outer limit member 1 and the second outer limit member 2.

[0073] In some other optional embodiments, the spacing between the first outer limit member 1 and the first inner limit member 3, and between the second outer limit member 2 and the second inner limit member 4 can be adjusted by a sixth screw (not shown) and a second locking nut (not shown). Specifically, taking the spacing between the first outer limit member 1 and the first inner limit member 3 as an example, the first outer limit member 1 is provided with a ninth through-hole (not shown), and the first inner limit member 3 is correspondingly provided with a tenth through-hole (not shown). The sixth screw passes through the ninth through-hole and the tenth through-hole and is threadedly connected to the second locking nut. By screwing the second locking nut, the spacing between the screw head of the sixth screw and the second locking nut can be adjusted, and the spacing between the first outer limit member 1 and the first inner limit member 3 can be adjusted, and the spacing between the first outer limit member 1 and the first inner limit member 3 can be adjusted.

[0074] In some other optional embodiments, the spacing between the first outer limiter 1 and the first inner limiter 3, as well as between the second outer limiter 2 and the second inner limiter 4, can be adjusted by providing components such as a telescopic cylinder, an electric push rod, and a linear servo module. Taking the provision of an electric push rod to adjust the spacing between the first outer limiter 1 and the first inner limiter 3 as an example, the electric push rod (not shown) is located between the first outer limiter 1 and the first inner limiter 3, and the electric push rod includes a fixed portion and a telescopic portion, one of which is connected to the first outer limiter 1, and the other is connected to the first inner limiter 3. The telescopic portion is telescopic relative to the fixed portion, and can drive the first outer limiter 1 and the first inner limiter 3 to move closer to or away from each other along the first direction, thereby achieving adjustment of the spacing between the first outer limiter 1 and the first inner limiter 3.

[0075] In this embodiment, the second adjustment mechanism 52 includes a second abutting portion and a third abutting portion. The second abutting portion is movably provided along the first direction through the first outer limit member 1 and the first inner limit member 3 and abuts against the inner side of the second inner limit member 4. The third abutting portion is movably provided along the first direction through the second outer limit member 2 and the second inner limit member 4 and abuts against the inner side of the first inner limit member 3, so that the first inner limit member 3 and the second inner limit member 4 abut against the inner side of the magnetic ring 9 along the first direction. Specifically, by providing the second abutting portion and the third abutting portion, the inner sides of the first inner limit member 3 and the second inner limit member 4 can be abutted, so that the first inner limit member 3 and the second inner limit member 4 abut against the inner side of the magnetic ring 9 along the first direction. The second abutting portion is movable relative to the first outer limiting member 1 and the first inner limiting member 3 along the first direction, and the third abutting portion is movable relative to the second outer limiting member 2 and the second inner limiting member 4 along the first direction, so that the abutting distance between the second abutting portion and the third abutting portion can be adjusted, thereby abutting the first inner limiting member 3 and the second inner limiting member 4 at different intervals, thereby adapting to magnetic rings 9 of different thicknesses and ensuring that the first inner limiting member 3 and the second inner limiting member 4 fix the inner side of the magnetic ring 9 along the first direction. Specifically, the second abutting portion and the third abutting portion press the first inner limiting member 3 and the second inner limiting member 4 along the first direction, so that the first inner limiting member 3 and the second inner limiting member 4 respectively abut against the inner sides of the two second ring portions 91 of the magnetic ring 9.

[0076] In this embodiment, the second abutting portion includes a second screw 521, and the third abutting portion includes a third screw 522. The first outer limiting member 1 is provided with a first screw hole 12, and the first inner limiting member 3 is correspondingly provided with a fifth through-hole 32. The second screw 521 is threadedly connected to the first screw hole 12, and is passed through the fifth through-hole 32 to abut against the inner side of the second inner limiting member 4. The second outer limiting member 2 is provided with a second screw hole 22, and the second inner limiting member 4 is correspondingly provided with a sixth through-hole 42. The third screw 522 is threadedly connected to the second screw hole 22, and is passed through the sixth through-hole 42 to abut against the inner side of the first inner limiting member 3. Specifically, the first screw hole 12 and the fifth through-hole 32 are coaxially arranged, the second screw hole 22 and the sixth through-hole 42 are coaxially arranged, and the common axis of the first screw hole 12 and the fifth through-hole 32 is offset from the common axis of the second screw hole 22 and the sixth through-hole 42.

[0077] Specifically, by screwing the second screw 521, the distance between the second screw 521 and the inner portion of the first inner stopper 3 is adjusted, thereby adjusting the distance between the second screw 521 and the second inner stopper 4. By screwing the third screw 522, the distance between the third floor cabinet and the inner portion of the second inner stopper 4 is adjusted, thereby adjusting the distance between the third screw 522 and the first inner stopper 3. The second screw 521 and the third screw 522 cooperate to adjust the distance between the first inner stopper 3 and the second inner stopper 4, so that the first inner stopper 3 and the second inner stopper 4 can abut against the inner side of the second ring portion 91 of the magnetic ring 9, thereby adapting to the requirements of magnetic rings 9 of different thicknesses.

[0078] Exemplarily, the number of the second screws 521, the first screw holes 12, and the fifth through holes 32 is set in one-to-one correspondence, and the number of the third screws 522, the second screw holes 22, and the sixth through holes 42 is set in one-to-one correspondence.

[0079] For example, the first screw hole 12 and the second screw hole 22 are configured as M5 screw holes. The diameter of the fifth through hole 32 and the sixth through hole 42 is configured as 5 mm. The second screw 521 and the third screw 522 are configured as M5 screws.

[0080] In this embodiment, the first inner limit member 3 includes a first support member 33 and a first limit plate 34, and the first limit plate 34 is slidably provided on the first support member 33 along the second direction; the second inner limit member 4 includes a second support member 43 and a second limit plate 44, and the second limit plate 44 is slidably provided on the second support member 43 along the second direction. The first limit plate 34 and the second limit plate 44 are both in contact with the inner side of the magnetic ring 9. Specifically, the third through-hole 31 and the fifth through-hole 32 are provided on the first support member 33, and the fourth through-hole 41 and the sixth through-hole 42 are provided on the second support member 43. The cooperation between the second screw 521 and the third screw 522 can adjust the distance between the first support member 33 and the second support member 43, and thereby correspondingly adjust the distance between the first limit plate 34 and the second limit plate 44 along the first direction. Specifically, the first outer limiting member 1 and the first limiting plate 34 can abut against the inner and outer sides of one of the second ring portions 91 of the magnetic ring 9; the second outer limiting member 2 and the second limiting plate 44 can abut against the inner and outer sides of the other second ring portion 91 of the magnetic ring 9. Specifically, the number of first limiting plates 34 on the first support member 33 is set to at least two; the number of second limiting plates 44 on the second support member 43 is set to at least two. For magnetic rings 9 of different lengths, the extension lengths of their side walls along the second direction are different. By providing at least two first limiting plates 34 and second limiting plates 44, the positions of the first limiting plates 34 and the second limiting plates 44 along the second direction can be adjusted, thereby being able to adapt to the clamping requirements of magnetic rings 9 of different lengths and ensuring reliable fixation of the magnetic ring 9.

[0081] In this embodiment, the first support member 33 defines a first slot 331 extending along the second direction, and the first limiting plate 34 is slidably connected to the first slot 331. The second support member 43 defines a second slot 431 extending along the second direction, and the second limiting plate 44 is slidably connected to the second slot 431.

[0082] In some other optional embodiments, the second adjustment mechanism 52 can also be configured as a telescopic cylinder, an electric push rod, a linear servo module, etc. Taking the second adjustment mechanism 52 as an electric push rod as an example, the electric push rod (not shown) is located between the first inner limiter 3 and the second inner limiter 4. The electric push rod includes a fixed portion and a telescopic portion, one of which is connected to the first inner limiter 3, and the other is connected to the second inner limiter 4. The telescopic portion is extended and retracted relative to the fixed portion, which can drive the first inner limiter 3 and the second inner limiter 4 to move closer to or farther away from each other along the first direction, thereby adjusting the distance between the first inner limiter 3 and the second inner limiter 4.

[0083] For example, the first outer limit member 1 is provided with a first clearance groove 14 on the side facing the first inner limit member 3, and the first support member 33 is adapted to enter the first clearance groove 14 when adjusting the spacing. The second outer limit member 2 is provided with a second clearance groove 24 on the side facing the second inner limit member 4, and the second support member 43 is adapted to enter the second clearance groove 24 when adjusting the spacing. The provision of the first clearance groove 14 and the second clearance groove 24 can avoid interference with the movement of the first support member 33 and the second support member 43, ensuring that the first limit plate 34 on the first support member 33 can further approach the first outer limit member 1 along the first direction until the two are in contact, and the second limit plate 44 on the second support member 43 can further approach the second outer limit member 2 along the first direction until the two are in contact, thereby further expanding the width adaptation range of the magnetic ring 9.

[0084] In this embodiment, the magnetic ring mold further includes two third inner stoppers 6 supported on the first support member 33 and the second support member 43. The two third inner stoppers 6 are respectively used to abut against the inner side of the magnetic ring 9 along the second direction. Specifically, by providing two third inner stoppers 6, the two third inner stoppers 6 abut against the inner sides of the two second ring portions 91 of the magnetic ring 9 in a one-to-one correspondence, further ensuring the fixation of the inner side of the second ring portion 91 of the magnetic ring 9 along the second direction.

[0085] For example, the third inner stopper 6 is primarily used for a racetrack-shaped magnetic ring 9 having a semicircular first ring portion 92. The third inner stopper 6 is a semicircular plate, and the first ring portion 92 abuts against the outer side of the third inner stopper 6. The semicircular plate is able to fully fit the inner side of the semicircular first ring portion 92, ensuring that the magnetic ring 9 is fully fixed and that the two opposing sides of the magnetic ring 9 along the second direction are reliably and effectively positioned to prevent movement of the magnetic ring 9.

[0086] The third inner stopper 6 can theoretically also be applied to a rectangular magnetic ring 9 with a linear first ring portion 92. The third inner stopper 6 is configured as a rectangular plate, with the first ring portion 92 abutting against the outer side of the third inner stopper 6. The rectangular plate can fully fit within the inner side of the linear first ring portion 92, ensuring full fixation of the magnetic ring 9 and reliable and effective positioning of the two opposing sides of the magnetic ring 9 along the second direction, preventing movement of the magnetic ring 9.

[0087] In this embodiment, the magnetic ring mold further includes a third outer limiter 7, a fourth outer limiter 8, and a third adjustment mechanism 53. The third adjustment mechanism 53 is connected between the third outer limiter 7 and the fourth outer limiter 8 and is used to adjust the distance between the third outer limiter 7 and the fourth outer limiter 8 so that the third outer limiter 7 and the fourth outer limiter 8 abut against the outer side of the magnetic ring 9 along the second direction. Specifically, the third adjustment mechanism 53 adjusts the distance between the third outer limiter 7 and the fourth outer limiter 8 so that the third outer limiter 7 and the fourth outer limiter 8 abut against the outer sides of the two first ring portions 92 of the magnetic ring 9 in a one-to-one correspondence, thereby adapting to magnetic rings 9 of different lengths and ensuring that the outer sides of the first ring portions 92 of the magnetic ring 9 are fixed along the second direction.

[0088] Exemplarily, the third outer limiting member 7 and the fourth outer limiting member 8 are mainly applied to the rectangular magnetic ring 9 having a linear first ring portion 92. The third outer limiting member 7 and the fourth outer limiting member 8 are respectively configured as straight rods, and the third outer limiting member 7 and the fourth outer limiting member 8 abut against the outer sides of the two first ring portions 92 along the second direction. The third outer limiting member 7 and the fourth outer limiting member 8 can fully fit with the inner side of the first ring portion 92 to ensure that the magnetic ring 9 is fully fixed and prevent the magnetic ring 9 from moving.

[0089] Furthermore, the first outer stopper 1 defines a first elongated hole 13, and the second outer stopper 2 defines a second elongated hole 23. Both the first elongated hole 13 and the second elongated hole 23 extend in the second direction. One end of the third outer stopper 7 and the fourth outer stopper 8 are slidably connected to the first elongated hole 13, while the other end of the third outer stopper 7 and the fourth outer stopper 8 are slidably connected to the second elongated hole 23. The provision of the first elongated hole 13 and the second elongated hole 23 ensures that the third outer stopper 7 and the fourth outer stopper 8 can slide strictly in the second direction, ensuring reliable and stable movement of the third outer stopper 7 and the fourth outer stopper 8.

[0090] Optionally, the portion of the third outer limiting member 7 located between the first long hole 13 and the second long hole 23 is set as a straight line segment or a circular arc segment; the portion of the fourth outer limiting member 8 located between the first long hole 13 and the second long hole 23 is set as a straight line segment or a circular arc segment. Figure 7 The runway-shaped magnetic ring 9 shown in FIG. 1 is provided with a third outer stopper 7 and a fourth outer stopper 8 located between the first long hole 13 and the second long hole 23 as a straight line segment. Figure 4 Suitable for Figure 6 The runway-shaped magnetic ring 9 shown in FIG, the third outer limiter 7 and the fourth outer limiter 8 are located between the first long hole 13 and the second long hole 23 as arc segments, and the specific schematic diagram can be referred to Figure 5 shown.

[0091] It is worth mentioning that if the third outer stopper 7 and the fourth outer stopper 8 are lower in vertical height than the first ring portion 92 of the magnetic ring 9, that is, the upper portion of the first ring portion 92 of the magnetic ring 9 is exposed outside the third outer stopper 7 and the fourth outer stopper 8, curling may occur after the upper half of the magnetic ring 9 is heat-treated. To avoid this problem, a baffle structure can be placed between the third outer stopper 7 and the first ring portion 92 on the corresponding side, and between the fourth outer stopper 8 and the first ring portion 92 on the corresponding side. The height of the baffle structure should not be lower than the overall height of the first ring portion 92, thereby preventing curling.

[0092] In this embodiment, the third adjustment mechanism 53 includes a fourth screw 531 and a fifth screw 532. The third outer stopper 7 has a seventh through-hole 71 and a third screw hole 72 at its ends, respectively. The fourth outer stopper 8 has an eighth through-hole 81 and a fourth screw hole 82 at its ends, respectively. Along the second direction, the seventh through-hole 71 corresponds to the fourth screw hole 82, and the eighth through-hole 81 corresponds to the third screw hole 72. The fourth screw 531 passes through the seventh through-hole 71 and is threadedly connected to the fourth screw hole 82. The fifth screw 532 passes through the eighth through-hole 81 and is threadedly connected to the third screw hole 72.

[0093] Specifically, the third outer limiting member 7 is provided with a first connector 73 and a second connector 74 at opposite ends thereof, the first connector 73 is provided with a third screw hole 72, and the second connector 74 is provided with a seventh through-hole 71. The fourth outer limiting member 8 is provided with a third connector 83 and a fourth connector 84 at opposite ends thereof, the third connector 83 is provided with a fourth screw hole 82, and the fourth connector 84 is provided with an eighth through-hole 81. The third screw hole 72 and the fourth screw hole 82 are distributed on both sides of the magnetic ring mold along the second direction, and the seventh through-hole 71 and the eighth through-hole 81 are distributed on both sides of the magnetic ring mold along the second direction. For example, by screwing the fourth screw 531, the other fifth screw 532 can slide in the eighth through-hole 81, thereby adjusting the distance between the third outer limiting member 7 and the fourth outer limiting member 8 along the second direction, thereby being able to adapt to magnetic rings 9 of different lengths.

[0094] For example, the first connector 73 and the fourth connector 84 are located outside the first slot 13, and the second connector 74 and the third connector 83 are located outside the second slot 23. The dimensions of the first connector 73 and the fourth connector 84 are greater than the width of the first slot 13, and the dimensions of the second connector 74 and the third connector 83 are greater than the width of the second slot 23. This arrangement can also effectively limit the third and fourth outer limiting members 7 and 8, preventing them from falling out of the first and second slots 13 and 23, thereby ensuring the reliability and stability of the overall structural connection.

[0095] For example, the diameter of the seventh through hole 71 and the eighth through hole 81 is set to 5 mm. The third screw hole 72 and the fourth screw hole 82 are set to M5 screw holes, and the fourth screw 531 and the fifth screw 532 are set to M5 screws.

[0096] In some other optional embodiments, the third adjustment mechanism 53 can also be configured as a telescopic cylinder, an electric push rod, a linear servo module, etc. Taking the third adjustment mechanism 53 as an electric push rod as an example, the electric push rod (not shown) is located between the third outer limiter 7 and the fourth outer limiter 8. The electric push rod includes a fixed portion and a telescopic portion, one of which is connected to the third outer limiter 7, and the other is connected to the fourth outer limiter 8. The telescopic portion is extended relative to the fixed portion, which can drive the third outer limiter 7 and the fourth outer limiter 8 to move closer to or away from each other along the second direction, thereby adjusting the distance between the third outer limiter 7 and the fourth outer limiter 8.

[0097] Exemplarily, the material of the first outer limit member 1, the second outer limit member 2, the third outer limit member 7, the fourth outer limit member 8, the first inner limit member 3, the second inner limit member 4 and the third inner limit member 6 are all set to 304 stainless steel, which has the beneficial effects of high strength, corrosion resistance and long service life.

[0098] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
