[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0035] like Figure 1 As shown, the existing two-piece cutting blade includes a fixed blade 200 and a movable blade 300, which are arranged opposite to each other. Both the fixed blade 200 and the movable blade 300 have cavities 400. The product passes through the cavities 400 of the fixed blade 200 and the movable blade 300. The fixed blade 200 and the movable blade 300 are hydraulically offset and cut at a 45° angle. Affected by factors such as the thickness of the product material, the product material, and the product model, the thicker the product material, the higher the yield strength of the product, and the smaller the product model, the greater the required cutting shearing force, which makes the fixed blade 200 and / or the movable blade 300 prone to breakage. In addition, in order to cover products of different sizes, the design dimensions of the fixed blade 200 and the movable blade 300 that are conventionally matched with the equipment are generally 250mm*200mm*60mm, made of C12MoV material, and heat treated with HRC50-55, resulting in a high overall manufacturing cost. Therefore, it is necessary to design a cutting device that is both cost-effective and reduces the risk of damage to meet daily production needs.

[0036] The following is for reference. Figures 2-8 A cutting device 100 according to an embodiment of this application is described.

[0037] like Figure 2 and Figure 3 As shown, the cutting device 100 according to an embodiment of this application includes: a fixed blade assembly 1 and a moving blade assembly 2. The fixed blade assembly 1 includes: a fixed blade body 10 and a fixed blade box 20. The fixed blade box 20 is sleeved on the outside of the fixed blade body 10 and is detachably engaged with the fixed blade body 10. The fixed blade body 10 defines a first cavity 103. The moving blade assembly 2 includes: a moving blade body 30 and a moving blade box 40. The moving blade box 40 is sleeved on the outside of the moving blade body 30 and is detachably engaged with the moving blade body 30. The moving blade body 30 defines a second cavity 303. The first cavity 103 and the second cavity 303 are adapted to jointly accommodate a portion of the workpiece to be cut. The moving blade assembly 2 is movable relative to the fixed blade assembly 1.

[0038] like Figure 2 and Figure 3As shown, the fixed blade assembly 1 of the cutting device 100 may include a fixed blade body 10 and a fixed blade housing 20, wherein the fixed blade housing 20 is sleeved on the outside of the fixed blade body 10, that is, at least a portion of the fixed blade body 10 is housed inside the fixed blade housing 20. The fixed blade body 10 and the fixed blade housing 20 are detachably coupled; for example, the fixed blade body 10 and the fixed blade housing 20 can be fixed by bolts, or the fixed blade body 10 and the fixed blade housing 20 can be fixed by snap-fit ​​connection. The fixed blade body 10 defines a first cavity 103, the first cavity 103 being along the thickness direction of the fixed blade body 10 (i.e., Figure 2 and Figure 4 The X direction shown penetrates through the fixed blade body 10. The first cavity 103 is used to accommodate the part to be cut. In other words, the part to be cut can be inserted into the first cavity 103.

[0039] like Figure 2 and Figure 3 As shown, the moving blade assembly 2 of the cutting device 100 may include a moving blade body 30 and a moving blade housing 40, wherein the moving blade housing 40 is sleeved on the outside of the moving blade body 30, that is, at least a portion of the moving blade body 30 is housed inside the moving blade housing 40. The moving blade body 30 and the moving blade housing 40 are detachably coupled; for example, the moving blade body 30 and the moving blade housing 40 can be fixed by bolts, or the moving blade body 30 and the moving blade housing 40 can be fixed by snap-fit ​​connection. The moving blade body defines a second cavity 303. The second cavity 303 extends along the thickness direction of the moving blade body 30 (i.e., Figure 2 and Figure 4 The second cavity 303 is used to accommodate the part to be cut (in the X direction shown). In other words, the part to be cut can be inserted into the second cavity 303.

[0040] As some embodiments of this application, the first cavity 103 of the fixed blade body 10 and the second cavity 303 of the movable blade body 30 may have the same shape and size, and the shapes of the first cavity 103 and the second cavity 303 are adapted to the shape of the workpiece to be cut, and the first cavity 103 of the fixed blade body 10 and the second cavity 303 of the movable blade body 30 together accommodate a portion of the workpiece to be cut.

[0041] The fixed blade assembly 1 is movable relative to the moving blade assembly 2 to cut the workpiece. In some embodiments of this application, when the cutting device 100 is operating, the moving blade assembly 2 moves offset relative to the fixed blade assembly 1 to cut the workpiece; when the cutting device 100 is idle, the moving blade assembly 2 and the fixed blade assembly 1 are relatively stationary. In some embodiments of this application, the workpiece to be cut can be a C-shaped steel.

[0042] It should be noted that by fitting the fixed blade box 20 onto the outside of the fixed blade body 10 and detachably engaging with it, and by fitting the movable blade box 40 onto the outside of the movable blade body 30 and detachably engaging with it, the fixed blade box 20 and the movable blade box 40 can be used as common parts of the cutting device 100. Furthermore, since the fixed blade box 20 is fitted onto the outside of the fixed blade body 10 and the movable blade box 40 is fitted onto the outside of the movable blade body 30, the length and width dimensions of the fixed blade body 10 and the movable blade body 30 can be significantly reduced. Therefore, the thickness of the fixed blade body 10 and the movable blade body 30 can be increased without increasing or even reducing manufacturing costs. This can increase the thickness of the weak points of the first cavity 103 and the second cavity 303, reducing the risk of breakage at the weak points of the first cavity 103 and the second cavity 303.

[0043] Furthermore, since the fixed blade box 20 and the moving blade box 40 are common parts of the cutting device 100, a larger number of fixed blade bodies 10 and moving blade bodies 30 can be produced and a smaller number of fixed blade boxes 20 and moving blade boxes 40 can be produced, which helps to reduce processing and transportation costs, and also reduces the difficulty of handling and installation during production changeover.

[0044] Therefore, the fixed blade box 20 and the moving blade box 40 can be used as general-purpose parts of the cutting device 100, and the length and width of the fixed blade body 10 and the moving blade body 30 can be greatly reduced. This allows the thickness of the fixed blade body 10 and the moving blade body 30 to be increased without increasing or even reducing manufacturing costs, thereby reducing the risk of breakage of the fixed blade body 10 and the moving blade body 30, improving reliability, and facilitating processing and transportation. In addition, the fixed blade body 10 and the moving blade body 30 can be replaced according to different sizes and materials of the workpiece to be cut, resulting in good adaptability.

[0045] In some embodiments of this application, such as Figures 2-4 As shown, the fixed tool box 20 includes: a first box body 201 and a first fixing member 202. The first fixing member 202 is disposed on the first box body 201. Along the thickness direction of the first box body 201, the first box body 201 has a first through hole 2011. A portion of the fixed tool body 10 is accommodated in the first through hole 2011. The first fixing member 202 is used to fix the fixed tool body 10.

[0046] The fixed tool box 20 may include a first box body 201 and a first fixing member 202. The first fixing member 202 may be disposed on the first box body 201. As some embodiments of this application, the first fixing member 202 may be disposed on the first box body 201 by means of, but not limited to, bolt connection, snap connection, etc. Along the thickness direction of the first box body 201 (i.e., along the thickness direction of the first box body 201) Figure 2 and Figure 4(As shown in the X direction), the first housing body 201 has a first through hole 2011, that is, the first through hole 2011 penetrates the first housing body 201 along the thickness direction of the first housing body 201, and part of the structure of the fixed blade body 10 is accommodated in the first through hole 2011. The first fixing member 202 is used to fix the fixed blade body 10. As some embodiments of this application, the first fixing member 202 can limit the fixed blade body 10 to restrict the displacement of the fixed blade body 10 relative to the fixed blade box 20.

[0047] By housing a portion of the fixed blade body 10 within the first through hole 2011, the thickness of the fixed blade body 10 can be greater than the thickness of the first housing body 201. This allows for a smaller thickness of the first housing body 201, reducing its manufacturing cost. Furthermore, the larger thickness of the fixed blade body 10 reduces the risk of breakage. Additionally, fixing the fixed blade body 10 with the first fixing member 202 improves its installation stability, reduces the risk of displacement of the fixed blade body 10 relative to the first housing body 201, and enhances the reliability of the cutting device 100.

[0048] In some embodiments of this application, such as Figure 5 As shown, the fixed blade body 10 includes: a first blade body 101 and a second blade body 102. The first blade body 101 is connected to the second blade body 102 and is housed in the first through hole 2011. The surface area of ​​the second blade body 102 facing the first blade body 101 is larger than the surface area of ​​the first blade body 101 facing the second blade body 102. The second blade body 102 can abut against the first housing body 201.

[0049] The fixed blade body 10 may include a first blade body 101 and a second blade body 102. The first blade body 101 and the second blade body 102 of the cutting device 100 may be connected by welding or integrally formed. The first housing body 201 is sleeved on the first blade body 101, or in other words, the first blade body 101 is received in the first through hole 2011 of the first housing body 201.

[0050] like Figure 5 As shown, the first blade body 101 is connected to the second blade body 102, and the surface area of ​​the second blade body 102 facing the first blade body 101 is greater than the surface area of ​​the first blade body 101 facing the second blade body 102. In other words, a plane is defined that is perpendicular to the thickness direction of the first box body 201 (i.e., Figure 2 and Figure 4 The X-direction shown is perpendicular to the plane, meaning the normal to this plane is perpendicular to the thickness direction of the first box body 201 (i.e., the X-direction shown). Figure 2 and Figure 4Parallel to the X direction shown, the projected area of ​​the surface of the second blade 102 facing the first blade 101 on this plane is larger than the projected area of ​​the surface of the first blade 101 facing the second blade 102 on this plane, and the projection of the surface of the second blade 102 facing the first blade 101 on this plane encompasses the projection of the surface of the first blade 101 facing the second blade 102 on this plane. The second blade 102 can abut against the first housing body 201.

[0051] This configuration facilitates quick identification of the portion of the fixed blade 10 housed in the first through hole 2011. Furthermore, when the first blade 101 is installed in place, the second blade 102 can abut against the surface of the first housing body 201, which facilitates the rapid positioning of the fixed blade 10 and reduces the risk of the fixed blade 10 being installed too deeply, thereby improving ease of use.

[0052] Understandably, the thickness of the fixed blade body 10 can be adjusted according to actual production needs. For example, the thicker and smaller the C-shaped steel material, the higher its yield strength and the greater the required shearing force. In such cases, the thickness of the fixed blade body 10 can be appropriately increased to reduce the risk of breakage.

[0053] In some embodiments of this application, such as Figures 2-4 As shown, there are multiple first fixing members 202, which are arranged around the fixed tool body 10.

[0054] The number of first fixing members 202 can be multiple, for example, two, four, six, etc. Multiple first fixing members 202 are arranged around the fixed tool body 10, and all multiple first fixing members 202 are used to fix the fixed tool body 10. In some embodiments of this application, the number of first fixing members 202 is two, and the two first fixing members 202 are distributed on opposite sides of the fixed tool body 10. In some embodiments of this application, the number of first fixing members 202 is four, and the four first fixing members 202 are arranged circumferentially and surround the fixed tool body 10.

[0055] This configuration can significantly improve the installation stability of the fixed blade body 10, further reduce the risk of displacement of the fixed blade body 10 relative to the first box body 201, and improve the reliability of the cutting device 100.

[0056] In some embodiments of this application, such as Figure 7 As shown, the first fixing member 202 includes: a first fixing part 2021 and a second fixing part 2022. The first fixing part 2021 is connected between the second fixing part 2022 and the first housing body 201. The second fixing part 2022 and the first fixing part 2021 have an included angle. The second fixing part 2022 is located on the side of the fixed blade body 10 away from the moving blade assembly 2 and corresponds to the fixed blade body 10.

[0057] The first fixing member 202 may include a first fixing part 2021 and a second fixing part 2022. The first fixing part 2021 and the second fixing part 2022 may be connected by means of, but not limited to, bolts, snap-fit, etc. As some embodiments of this application, the first fixing part 2021 and the second fixing part 2022 are constructed as an integrally formed part. As some embodiments of this application, the first fixing part 2021 and the first box body 201 may be connected by means of, but not limited to, bolts, snap-fit, etc. The first fixing part 2021 may extend along the thickness direction of the first box body 201. As some embodiments of this application, one end of the first fixing part 2021 contacts the first box body 201, and the other end of the first fixing part 2021 (the end of the first fixing part 2021 closer to the second fixing part 2022) is connected to the second fixing part 2022. The second fixing part 2022 and the first fixing part 2021 have an included angle, for example, the first fixing part 2021 and the second fixing part 2022 are arranged in a "L" shape. The second fixing part 2022 is located on the side of the fixed blade body 10 away from the moving blade body 30 and corresponds to the fixed blade body 10. In other words, a plane is set that is perpendicular to the thickness direction of the first box body 201 (i.e., Figure 2 and Figure 4 The X-direction shown is perpendicular to the plane, meaning the normal to this plane is perpendicular to the thickness direction of the first box body 201 (i.e., the X-direction shown). Figure 2 and Figure 4 Parallel to the X direction shown, the projection of the fixed blade 10 on this plane and the projection of the second fixed part 2022 on this plane have an overlapping area.

[0058] As some embodiments of this application, such as Figures 2-4 As shown, there are two first fasteners 202, which are arranged opposite each other and spaced apart. The second fastening part 2022 of each first fastener 202 extends toward the other first fastener 202.

[0059] This configuration allows the first fixing member 202 to limit the fixed blade body 10 in the thickness direction of the first housing body 201 (i.e., Figure 2 and Figure 4 The movement of the fixed blade 10 in the X direction (as shown) reduces the risk of the fixed blade 10 detaching from the first housing body 201, and restricts the movement of the fixed blade 10 in the direction perpendicular to the thickness of the first housing body 201, thereby significantly improving the installation stability of the fixed blade 10 and enhancing the reliability of the cutting device 100. It is understood that the first blade 101 mates with the first through hole 2011, and the second blade 102 mates with the first fixing member 202.

[0060] In some embodiments of this application, such as Figures 2-4 As shown, the first fastener 202 is detachably connected to the first box body 201.

[0061] The first fixing member 202 and the first box body 201 can be fixed by bolts or snap-fit ​​connection, so that the first fixing member 202 and the first box body 201 are detachably connected. As some embodiments of this application, the first fixing member 202 and the first box body 201 are fixed by bolts. For example, the first box body 201 has threaded holes, the first fixing member 202 has mating holes, and there are multiple threaded holes, multiple mating holes, and multiple bolts. The number of threaded holes, mating holes, and bolts are the same and correspond one-to-one. The bolts pass through the corresponding mating holes and are threadedly connected to the corresponding threaded holes. It is understood that bolts can also be replaced by screws or other connecting parts.

[0062] By making the first fixing member 202 detachably connected to the first box body 201, it is convenient to disassemble and assemble the fixed blade body 10, and the operation is convenient. Furthermore, the damaged first fixing member 202 or the first box body 201 can be replaced, which helps to save costs and has good economic efficiency. In addition, the first fixing member 202 of different sizes can be replaced according to the thickness of the fixed blade body 10, which helps to improve the versatility and compatibility of the fixed blade box 20.

[0063] In some embodiments of this application, such as Figures 2-4 As shown, the movable tool box 40 includes: a second box body 401 and a second fixing member 402. The second fixing member 402 is disposed on the second box body 401. Along the thickness direction of the second box body 401, the second box body 401 has a second through hole 4011. Part of the structure of the movable tool body 30 is accommodated in the second through hole 4011. The second fixing member 402 is used to fix the movable tool body 30.

[0064] The moving tool box 40 may include a second box body 401 and a second fixing member 402. The second fixing member 402 may be disposed on the second box body 401. As some embodiments of this application, the second fixing member 402 may be disposed on the second box body 401 by means of, but not limited to, bolt connection, snap connection, etc. Along the thickness direction of the second box body 401 (i.e., along the thickness direction of the second box body 401) Figure 2 and Figure 4 (As shown in the X direction), the second housing body 401 has a second through hole 4011, that is, the second through hole 4011 penetrates the second housing body 401 along the thickness direction of the second housing body 401, and part of the structure of the moving blade 30 is accommodated in the second through hole 4011. The second fixing member 402 is used to fix the moving blade 30. As some embodiments of this application, the second fixing member 402 can limit the moving blade 30 to restrict the displacement of the moving blade 30 relative to the moving blade box 40.

[0065] By housing a portion of the moving blade body 30 within the second through hole 4011, the thickness of the moving blade body 30 can be greater than the thickness of the second housing body 401. This allows for a smaller thickness of the second housing body 401, reducing its manufacturing cost. Furthermore, the larger thickness of the moving blade body 30 reduces the risk of breakage. Additionally, fixing the moving blade body 30 with the second fastener 402 improves its installation stability, reduces the risk of displacement of the moving blade body 30 relative to the second housing body 401, and enhances the reliability of the cutting device 100.

[0066] In some embodiments of this application, such as Figure 6 As shown, the moving blade body 30 includes a third blade body 301 and a fourth blade body 302. The third blade body 301 and the fourth blade body 302 are connected and housed in the second through hole 4011. The surface area of ​​the fourth blade body 302 facing the third blade body 301 is larger than the surface area of ​​the third blade body 301 facing the fourth blade body 302. The fourth blade body 302 can abut against the second housing body 401.

[0067] The moving blade body 30 may include a third blade body 301 and a fourth blade body 302. The third blade body 301 and the fourth blade body 302 of the cutting device 100 may be connected by welding or integrally formed. The second housing body 401 is sleeved on the third blade body 301, or in other words, the third blade body 301 is received in the second through hole 4011 of the second housing body 401.

[0068] like Figure 6 As shown, the third blade 301 is connected to the fourth blade 302, and the surface area of ​​the fourth blade 302 facing the third blade 301 is greater than the surface area of ​​the third blade 301 facing the fourth blade 302. In other words, a plane is defined that is perpendicular to the thickness direction of the second box body 401 (i.e., Figure 2 and Figure 4 The X direction shown is perpendicular to the plane, meaning the normal to this plane is perpendicular to the thickness direction of the second box body 401 (i.e., the X direction shown). Figure 2 and Figure 4 Parallel to the X direction shown, the projected area of ​​the surface of the fourth cutter 302 facing the third cutter 301 on this plane is larger than the projected area of ​​the surface of the third cutter 301 facing the fourth cutter 302 on this plane, and the projection of the surface of the fourth cutter 302 facing the third cutter 301 on this plane encompasses the projection of the surface of the third cutter 301 facing the fourth cutter 302 on this plane. The fourth cutter 302 can abut against the second box body 401.

[0069] This arrangement facilitates quick identification of the portion of the movable blade 30 housed in the second through hole 4011. Furthermore, when the third blade 301 is installed in place, the fourth blade 302 can abut against the surface of the second housing body 401, which facilitates the rapid positioning of the movable blade 30 and reduces the risk of the movable blade 30 being installed too deeply, thereby improving ease of use.

[0070] Understandably, the thickness of the moving cutter body 30 can be adjusted according to actual production needs. For example, the thicker and smaller the C-shaped steel material, the higher its yield strength and the greater the required shearing force. In such cases, the thickness of the moving cutter body 30 can be appropriately increased to reduce the risk of breakage.

[0071] In some embodiments of this application, such as Figures 2-4 As shown, there are multiple second fixing members 402, which are arranged around the moving cutter body 30.

[0072] The number of second fixing members 402 can be multiple, for example, two, four, six, etc. Multiple second fixing members 402 are arranged around the moving cutter body 30, and all of them are used to fix the moving cutter body 30. In some embodiments of this application, there are two second fixing members 402, distributed on opposite sides of the moving cutter body 30. In some embodiments of this application, there are four second fixing members 402, arranged circumferentially and surrounding the moving cutter body 30.

[0073] This configuration can significantly improve the installation stability of the moving blade body 30, further reduce the risk of displacement of the moving blade body 30 relative to the second housing body 401, and improve the reliability of the cutting device 100.

[0074] In some embodiments of this application, such as Figure 8 As shown, the second fixing member 402 includes a third fixing member 4021 and a fourth fixing member 4022. The third fixing member 4021 is connected between the fourth fixing member 4022 and the second housing body 401. The fourth fixing member 4022 and the third fixing member 4021 have an included angle. The fourth fixing member 4022 is located on the side of the moving blade body 30 away from the moving blade assembly 2 and corresponds to the moving blade body 30.

[0075] The second fixing member 402 may include a third fixing member 4021 and a fourth fixing member 4022. The third fixing member 4021 and the fourth fixing member 4022 may be connected by means of, but not limited to, bolts, snap-fit, etc. As some embodiments of this application, the third fixing member 4021 and the fourth fixing member 4022 are constructed as an integrally formed part. As some embodiments of this application, the third fixing member 4021 and the second box body 401 may be connected by means of, but not limited to, bolts, snap-fit, etc. The third fixing member 4021 may extend along the thickness direction of the second box body 401. As some embodiments of this application, one end of the third fixing member 4021 contacts the second box body 401, and the other end of the third fixing member 4021 (the end of the third fixing member 4021 closer to the fourth fixing member 4022) is connected to the fourth fixing member 4022. The fourth fixing member 4022 and the third fixing member 4021 have an included angle. For example, the third fixing member 4021 and the fourth fixing member 4022 are arranged in a "L" shape. The fourth fixing member 4022 is located on the side of the moving cutter body 30 away from the moving cutter body 30 and corresponds to the moving cutter body 30. In other words, a plane is set that is perpendicular to the thickness direction of the second box body 401 (i.e., Figure 2 and Figure 4 The X direction shown is perpendicular to the plane, meaning the normal to this plane is perpendicular to the thickness direction of the second box body 401 (i.e., the X direction shown). Figure 2 and Figure 4 Parallel to the X direction shown, the projection of the moving blade 30 on this plane overlaps with the projection of the fourth fixing member 4022 on this plane.

[0076] As some embodiments of this application, such as Figures 2-4 As shown, there are two second fasteners 402, which are arranged opposite each other and spaced apart. The fourth fastener 4022 of each second fastener 402 extends toward the other second fastener 402.

[0077] This configuration allows the moving cutter body 30 to be limited in the thickness direction of the second housing body 401 by the second fixing member 402 (i.e., Figure 2 and Figure 4 The movement of the moving blade 30 in the X direction (as shown) reduces the risk of the moving blade 30 detaching from the second housing body 401, and restricts the movement of the moving blade 30 in the direction perpendicular to the thickness of the second housing body 401, thereby significantly improving the installation stability of the moving blade 30 and enhancing the reliability of the cutting device 100. It is understood that the third blade 301 mates with the second through hole 4011, and the fourth blade 302 mates with the second fixing member 402.

[0078] In some embodiments of this application, such as Figures 2-4 As shown, the second fastener 402 is detachably connected to the second box body 401.

[0079] The second fixing member 402 and the second box body 401 can be fixed by bolts or snap-fit ​​connection, so that the second fixing member 402 and the second box body 401 are detachably connected. As some embodiments of this application, the second fixing member 402 and the second box body 401 are fixed by bolts. For example, the second box body 401 has threaded holes, the second fixing member 402 has mating holes, and there are multiple threaded holes, multiple mating holes, and multiple bolts. The number of threaded holes, mating holes, and bolts are the same and correspond one-to-one. The bolts pass through the corresponding mating holes and are threadedly connected to the corresponding threaded holes. It is understood that bolts can also be replaced by screws or other connecting parts.

[0080] By making the second fixing member 402 detachably connected to the second box body 401, it is convenient to disassemble and assemble the moving blade body 30, making the operation convenient. Furthermore, the damaged second fixing member 402 or the second box body 401 can be replaced, which helps to save costs and has good economic efficiency. In addition, the second fixing member 402 of different sizes can be replaced according to the thickness of the moving blade body 30, which helps to improve the versatility and compatibility of the moving blade box 40.

[0081] As some embodiments of this application, the fixed tool box 20 and the moving tool box 40 may have the same structure, and the fixed tool body 10 and the moving tool body 30 may have the same structure.

[0082] The shearing mechanism according to the embodiments of this application includes: a cutting device 100, a fixing device, and a driving device. The cutting device 100 is the cutting device 100 of the above embodiments. The fixed blade assembly 1 is disposed on the fixing device, and the moving blade assembly 2 is disposed on the driving device. The driving device can drive the moving blade assembly 2 to move relative to the fixed blade assembly 1.

[0083] As some embodiments of this application, the driving device can be configured as a hydraulic driving device, which can drive the moving blade assembly 2 to move in a staggered manner relative to the fixed blade assembly 1 to cut the C-shaped steel in a staggered cutting manner.

[0084] Therefore, the fixed blade box 20 and the moving blade box 40 can be used as general-purpose parts of the cutting device 100, and the length and width of the fixed blade body 10 and the moving blade body 30 can be greatly reduced. This allows the thickness of the fixed blade body 10 and the moving blade body 30 to be increased without increasing or even reducing manufacturing costs, thereby reducing the risk of breakage of the fixed blade body 10 and the moving blade body 30, improving reliability, and facilitating processing and transportation. In addition, the fixed blade body 10 and the moving blade body 30 can be replaced according to different sizes and materials of the workpiece to be cut, resulting in good adaptability.
