[0042] 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.

[0043] The following is for reference. Figures 1-9 A punching mechanism 100 according to an embodiment of this application is described.

[0044] like Figures 1-9 As shown, the punching mechanism 100 according to an embodiment of this application includes: a mold frame 10, a first sub-mold 20, and a drive assembly 60.

[0045] The mold base 10 includes a first mold base 11 and a second mold base 12, along the height direction of the punching mechanism 100 (i.e., Figure 1 The first mold frame 11 and the second mold frame 12 are spaced apart and movable relative to the second mold frame 12; the first sub-mold 20 is movably disposed on the mold frame 10; the drive assembly 60 includes: a drive rod 61, which is assembled with the first sub-mold 20, and the drive rod 61 is used to drive the first sub-mold 20 along a first direction (i.e., the Z direction shown). Figure 1 Move in the X direction (as shown).

[0046] It should be noted that the punching mechanism 100 of this application can be used, but is not limited to, for punching the strip material before forming C-shaped steel rod products. This application will use the application of the punching mechanism 100 for punching the strip material before forming C-shaped steel rod products as an example for illustration, and will not be repeated below.

[0047] The mold frame 10 includes a first mold frame 11 and a second mold frame 12, which are located along the height direction of the punching mechanism 100 (i.e., Figure 1 (As shown in the Z direction), the first mold frame 11 and the second mold frame 12 are spaced apart. Specifically, there is a certain distance between the first mold frame 11 and the second mold frame 12, and the first mold frame 11 is positioned above the second mold frame 12. The first mold frame 11 is movable relative to the second mold frame 12. Specifically, the first mold frame 11 moves along the height direction of the punching mechanism 100 (i.e., along the Z direction). Figure 1 The Z-direction shown can be close to the second mold base 12, or the first mold base 11 along the height direction of the punching mechanism 100 (i.e., Figure 1 The Z direction shown can move away from the second mold frame 12.

[0048] The first sub-mold 20 is movably disposed on the mold frame 10. As some embodiments of this application, the mold frame 10 has a first direction (i.e., Figure 1 The first slide rail 42 extends in the X direction (as shown), and a portion of the first sub-mold 20 is located in the first slide rail 42, so that the first sub-mold 20 is along the first direction (i.e., Figure 1 The mold frame 10 is movable along the X direction (as shown in the diagram). As some embodiments of this application, the mold frame 10 has a first direction (i.e., the X direction shown in the diagram) and is mounted on the mold base 10. As part of some embodiments of this application, the mold base 10 has a first direction (i.e., the X direction shown in the diagram) and is movable along the mold base 10. Figure 1 A slide rail extending in the X direction (as shown) is provided. The first sub-mold 20 has a slider that engages with the slide rail to allow the first sub-mold 20 to move along the first direction (i.e., the X direction). Figure 1 The part shown in the X direction is movable and located on the mold frame 10.

[0049] The drive rod 61 can be engaged with the first sub-mold 20 by means of, but not limited to, snap-fit ​​or bolt connection. As some embodiments of this application, the drive rod 61 and the first sub-mold 20 are engaged by snap-fit.

[0050] Drive rod 61 can drive the first sub-mold 20 along the first direction (i.e. Figure 1 As some embodiments of this application, the drive assembly 60 further includes a drive member capable of driving the drive rod 61 to move along a first direction (i.e., the X direction shown). Figure 1 The first sub-module 20 is moved in the X direction (as shown) to change the direction along the first direction (i.e., Figure 1 The position shown in the X direction.

[0051] As some embodiments of this application, the drive rod 61 is constructed as a lead screw, and the drive assembly 60 further includes: a drive member and a fixing nut. The fixing nut is fixedly connected to the first sub-mold 20, and the drive rod 61 is threadedly engaged with the fixing nut. The drive member can control the drive rod 61 to rotate, so that the fixing nut rotates in a first direction (i.e., ...). Figure 1 The first sub-module 20 is moved in the X direction (as shown) to change the direction along the first direction (i.e., Figure 1The position shown in the X direction.

[0052] As some embodiments of this application, the drive rod 61 is constructed as a lead screw, and a fixing nut is fixedly provided on the second mold frame 12. The drive rod 61 cooperates with the first sub-mold 20, and the drive rod 61 can be rotated to move the drive rod 61 along a first direction (i.e., Figure 1 The first sub-module 20 is moved in the X direction (as shown) to change the direction along the first direction (i.e., Figure 1 The position shown in the X direction.

[0053] This configuration facilitates adjustment of the first sub-mold 20 along the first direction (i.e. Figure 1 The position in the X direction (as shown) allows the punching mechanism 100 to easily adjust the punching spacing, which helps improve the ease of use of the punching mechanism 100.

[0054] Thus, by enabling the drive component 60 to drive the first sub-module 20 along the first direction (i.e. Figure 1 The first sub-module 20 can be moved along the first direction (i.e., the X direction shown), which facilitates adjustment. Figure 1 The position of the punching mechanism 100 (in the X direction shown) can be adjusted to facilitate the adjustment of the punching spacing, enabling the punching mechanism 100 to be adapted to different products, thereby improving the versatility of the punching mechanism 100 and reducing the production cost of the products.

[0055] In some embodiments of this application, the first sub-mold 20 includes: a first template 21, a second template 22, and an ejector plate 23. The first template 21 is assembled with the first mold frame 11, the second template 22 is assembled with the second mold frame 12, and the ejector plate 23 is located at one end of the second template 22 near the first template 21 and together with the second template 22 defines the feeding space 24.

[0056] The first sub-mold 20 includes a first template 21, a second template 22, and an ejector plate 23. The first template 21 is assembled with the first mold frame 11. In some embodiments of this application, the first template 21 and the first mold frame 11 are connected by a snap-fit ​​mechanism. The second template 22 is assembled with the second mold frame 12. In some embodiments of this application, the second template 22 and the second mold frame 12 are connected by a snap-fit ​​mechanism.

[0057] The ejector plate 23 is located at one end of the second template 22 near the first template 21 and together with the second template 22 defines the feeding space 24. That is, the ejector plate 23 is located between the second template 22 and the first template 21. In some embodiments of this application, the ejector plate 23 and the second template 22 are connected by bolts. Furthermore, the ejector plate 23 and the second template 22 together define the feeding space 24, which can accommodate at least a portion of the strip material before forming.

[0058] This configuration makes the punching mechanism 100 simple and reasonable, facilitates its installation and disassembly, and allows the strip to be ejected by the ejector plate 23, reducing the risk of the strip moving toward the first template 21 during punching, thus improving the reliability of the punching mechanism 100.

[0059] In some embodiments of this application, such as Figures 2-4 , Figure 8 As shown, the punching mechanism 100 further includes: a first pressure plate 41, which is disposed on the first mold frame 11 and together with the first mold frame 11 defines a first direction (i.e., Figure 1 The first slide rail 42 extends in the X direction (as shown), and a portion of the first template 21 is located in the first slide rail 42, and along the height direction of the punching mechanism 100 (i.e., Figure 1 (As shown in the Z direction), part of the first template 21 is located between the first pressure plate 41 and the first mold frame 11.

[0060] The first pressure plate 41 is disposed on the first mold frame 11. The connection between the first pressure plate 41 and the first mold frame 11 can be, but is not limited to, welding, bolt connection, etc. As some embodiments of this application, the first pressure plate 41 and the first mold frame 11 are connected by bolt connection.

[0061] The first pressure plate 41 and the first mold frame 11 together define the area along the first direction (i.e. Figure 1 The first slide rail 42 extends in the X direction (as shown), specifically, a portion of the first pressure plate 41 and the first mold frame 11 are along the height direction of the punching mechanism 100 (i.e., Figure 1 The Z-direction shown has a certain interval to define the first slide rail 42, the first slide rail 42 along the first direction (i.e. Figure 1 The first template 21 is extended along the X direction (as shown), and a portion of its structure is located on the first slide rail 42, so that the first template 21 can extend along the first direction (i.e., Figure 1 (Movement in the X direction as shown).

[0062] Along the height direction of the punching mechanism 100 (i.e. Figure 1 As shown in the Z direction, part of the first template 21 is located between the first pressure plate 41 and the first mold frame 11. That is to say, part of the structure of the first template 21 can be along the height direction of the punching mechanism 100 (i.e., Figure 1 The first template 21 (shown in the Z direction) is sandwiched between the first pressure plate 41 and the first mold frame 11. Under the action of the first pressure plate 41, the first template 21 can follow the first mold frame 11 along the height direction of the punching mechanism 100 (i.e., the Z direction). Figure 1 (The movement is in the Z direction as shown).

[0063] This configuration facilitates the first template 21 along the first direction (i.e. Figure 1The movement (in the X direction shown) can improve the stability of the sliding of the first template 21, and can also improve the stability of the first template 21 along the height direction (i.e., Figure 1 The first template 21 is constrained in the Z direction (as shown) so that it can follow the movement of the first mold frame 11, which helps to improve the reliability of the punching mechanism 100.

[0064] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the punching mechanism 100 further includes: a second pressure plate 43, which is disposed on the second mold frame 12 and together with the second mold frame 12 defines a direction along the first direction (i.e., Figure 1 The second slide rail 44 extends in the X direction (as shown), and a portion of the second template 22 is located in the second slide rail 44, and along the height direction of the punching mechanism 100 (i.e., Figure 1 (As shown in the Z direction), part of the second template 22 is located between the second pressure plate 43 and the second mold frame 12.

[0065] The second pressure plate 43 is disposed on the second mold frame 12. The connection between the second pressure plate 43 and the second mold frame 12 can be, but is not limited to, welding, bolt connection, etc. As some embodiments of this application, the second pressure plate 43 and the second mold frame 12 are connected by bolt connection.

[0066] The second pressure plate 43 and the second mold frame 12 together define the area along the first direction (i.e. Figure 1 The second slide 44 extends in the X direction (as shown), specifically, a portion of the second pressure plate 43 and the second mold frame 12 extend along the height direction of the punching mechanism 100 (i.e., Figure 1 The Z-direction shown has a certain interval to define the second slide 44, which is along the first direction (i.e. Figure 1 The second template 22 is extended along the X direction (as shown), and a portion of its structure is located in the second slide rail 44, so that the second template 22 can extend along the first direction (i.e., Figure 1 (Movement in the X direction as shown).

[0067] Along the height direction of the punching mechanism 100 (i.e. Figure 1 As shown in the Z direction), part of the second template 22 is located between the second pressure plate 43 and the second mold frame 12. That is to say, part of the structure of the second template 22 can be along the height direction of the punching mechanism 100 (i.e., Figure 1 The Z direction shown is located between the second pressure plate 43 and the second mold frame 12. Under the action of the second pressure plate 43, the second template 22 can be constrained to the second mold frame 12 so as to stabilize the sliding of the first sub-mold 20.

[0068] This arrangement facilitates the second template 22 along the first direction (i.e. Figure 1The movement (in the X direction shown) can improve the stability of the sliding of the second template 22, and can also improve the stability of the second template 22 along the height direction (i.e., Figure 1 The Z-direction shown is constrained to reduce the risk of the second template 22 following the movement of the first mold frame 11, which is beneficial to improving the reliability of the punching mechanism 100.

[0069] In some embodiments of this application, such as Figures 2-4 As shown, there are multiple first pressure plates 41, along the second direction (i.e. Figure 1 In the Y direction shown, at least one first pressure plate 41 is provided on both sides of the first template 21, and in the second direction (i.e. Figure 1 The Y-direction shown), the height direction of the punching mechanism 100 (i.e., the height direction of the punching mechanism 100) Figure 1 The Z direction shown), the first direction (i.e. Figure 1 Any two of the X directions shown are perpendicular to each other.

[0070] The number of first pressure plates 41 can be multiple, including but not limited to two, three, four, etc. In some embodiments of this application, the number of first pressure plates 41 is two. Along the second direction (i.e....) Figure 1 As shown in the Y direction), at least one first pressure plate 41 is provided on both sides of the first template 21, that is, along the second direction (i.e. Figure 1 As shown in the Y direction), a first pressure plate 41 is provided on both sides of the first template 21, or, along the second direction (i.e. Figure 1 As shown in the Y direction), the first template 21 has multiple first pressure plates 41 on both sides. As some embodiments of this application, along the second direction (i.e. Figure 1 (As shown in the Y direction), a first pressure plate 41 is provided on both sides of the first template 21.

[0071] The second direction (i.e.) Figure 1 The Y-direction shown), the height direction of the punching mechanism 100 (i.e., the height direction of the punching mechanism 100) Figure 1 The Z direction shown), the first direction (i.e. Figure 1 Any two of the X directions shown are perpendicular to each other, that is, the second direction (i.e., Figure 1 The Y-direction shown is parallel to the height direction of the punching mechanism 100 (i.e., the direction of the punching mechanism 100). Figure 1 The Z-direction shown is perpendicular to each other, and the second direction (i.e. Figure 1 The Y direction shown) and the first direction (i.e. Figure 1 The X directions shown are perpendicular to each other, and the first direction (i.e. Figure 1 The X direction shown is perpendicular to the height direction of the punching mechanism 100 (i.e., the direction of X). Figure 1 The Z-direction shown is perpendicular to each other.

[0072] This configuration allows the first template 21 to slide stably along the first slide rail 42, reducing the risk of the first template 21 detaching from the first slide rail 42 and the risk of the first template 21 shifting or deviating, thus improving the stability of the sliding of the first template 21. Furthermore, this also improves the stability of the first template 21 moving with the first mold frame 11.

[0073] In some embodiments of this application, such as Figures 2-4 As shown, there are multiple second pressure plates 43, along the second direction (i.e. Figure 1 As shown in the Y direction), at least one second pressure plate 43 is provided on both sides of the second template 22, in the second direction (i.e. Figure 1 The Y-direction shown), the height direction of the punching mechanism 100 (i.e., the height direction of the punching mechanism 100) Figure 1 The Z direction shown), the first direction (i.e. Figure 1 Any two of the X directions shown are perpendicular to each other.

[0074] The number of second pressure plates 43 is multiple, including but not limited to two, three, four, etc. In some embodiments of this application, the number of second pressure plates 43 is two. Along the second direction (i.e....) Figure 1 As shown in the Y direction), at least one second pressure plate 43 is provided on both sides of the second template 22, that is, along the second direction (i.e. Figure 1 As shown in the Y direction), a second pressure plate 43 is provided on both sides of the second template 22, or, along the second direction (i.e., Figure 1 As shown in the Y direction), the second template 22 has multiple second pressure plates 43 on both sides. As some embodiments of this application, along the second direction (i.e. Figure 1 (As shown in the Y direction), a second pressure plate 43 is provided on both sides of the second template 22.

[0075] This configuration allows the second template 22 to slide stably along the second slide rail 44, reduces the risk of the second template 22 detaching from the second slide rail 44, and also reduces the risk of the second template 22 shifting or deviating, which helps to improve the stability of the sliding of the second template 22.

[0076] In some embodiments of this application, such as Figure 3 As shown, the first mold frame 11 has a first groove 45, and part of the structure of the first template 21 is disposed in the first groove 45.

[0077] The first groove 45 is along the height direction of the punching mechanism 100 (i.e. Figure 1 The Z-direction shown is recessed in the direction away from the first template 21, and part of the structure of the first template 21 is located in the first groove 45.

[0078] By forming a first groove 45 in the first mold frame 11 and setting part of the structure of the first template 21 in the first groove 45, the first template 21 is placed stably in the first slide rail 42. Thus, the movement direction of the first template 21 can be restricted by the first groove 45, reducing the risk of the first template 21 moving off-center.

[0079] In some embodiments of this application, such as Figure 3 , Figure 8 As shown, the second mold frame 12 has a second groove 46, and part of the structure of the second template 22 is disposed in the second groove 46.

[0080] Wherein, the second groove 46 is along the height direction of the punching mechanism 100 (i.e. Figure 1 The Z-direction shown is recessed in the direction away from the second template 22, and part of the structure of the second template 22 is located in the second groove 46.

[0081] By forming a second groove 46 in the second mold frame 12 and setting part of the structure of the second template 22 in the second groove 46, the second template 22 is placed stably in the second slide rail 44. Thus, the movement direction of the second template 22 can be restricted by the second groove 46, reducing the risk of the second template 22 shifting.

[0082] In some embodiments of this application, such as Figure 2 , Figures 4-6 , Figure 8 As shown, the punching mechanism 100 further includes a first guide post 51, which is disposed in one of the first mold frame 11 and the second mold frame 12 and passes through the other of the first mold frame 11 and the second mold frame 12, so that the first mold frame 11 and the second mold frame 12 are guided and engaged.

[0083] The first guide post 51 is disposed in one of the first mold frame 11 and the second mold frame 12 and passes through the other of the first mold frame 11 and the second mold frame 12. That is, the first guide post 51 can be disposed in the first mold frame 11 and pass through the second mold frame 12, or the first guide post 51 can be disposed in the second mold frame 12 and pass through the first mold frame 11. As some embodiments of this application, the first guide post 51 is disposed in the first mold frame 11 and passes through the second mold frame 12 so that the first mold frame 11 and the second mold frame 12 are guided and matched.

[0084] By including a first guide post 51 in the punching mechanism 100, the movement of the first mold base 11 can be guided so that the movement direction of the first punch 313 is accurate and the risk of the first punch 313 moving off-center is reduced.

[0085] As some embodiments of this application, such as Figure 2 , Figures 4-6 , Figure 8 As shown, the punching mechanism 100 further includes: a first guide bushing 52; a first guide post 51 disposed in one of the first mold frame 11 and the second mold frame 12; the first guide bushing 52 passing through the other of the first mold frame 11 and the second mold frame 12; the first guide post 51 passing through the first guide bushing 52 and guidingly engaging with the first guide bushing 52, so that the first mold frame 11 and the second mold frame 12 are guidedly engaged. For example, the first guide post 51 is disposed in the first mold frame 11, the first guide bushing 52 passes through the second mold frame 12, and the first guide post 51 passes through the first guide bushing 52 and guidingly engaging with the first guide bushing 52, so that the first mold frame 11 and the second mold frame 12 are guidedly engaged.

[0086] This design improves guiding stability and increases guiding stroke, which in turn enhances the reliability of the punching mechanism 100.

[0087] In some embodiments of this application, such as Figure 5 As shown, the first sub-mold 20 also includes a pad 53, which is disposed between the ejector plate 23 and the second template 22 to define a feeding space 24 between the ejector plate 23 and the second template 22.

[0088] Among them, along the height direction of the punching mechanism 100 (i.e. Figure 1 (As shown in the Z direction), the pad 53 is disposed between the ejector plate 23 and the second template 22. The pad 53, the ejector plate 23, and the second template 22 can define the feeding space 24 so that the feeding space 24 can accommodate the material strip. That is, the pad 53 can be disposed between the ejector plate 23 and the second template 22 so that there is a certain distance between the ejector plate 23 and the second template 22, and the material strip can move along the second direction (i.e., the Z direction). Figure 1 (As shown in the Y direction) it enters the feeding space 24 to be punched. As some embodiments of this application, the pad 53, the ejector plate 23, and the second template 22 are connected by bolts.

[0089] This setup allows for a simple and reliable definition of the feeding space 24 between the ejector plate 23 and the second template 22, reducing the structural design difficulty of the first sub-mold 20.

[0090] In some embodiments of this application, such as Figure 5 , Figure 8 As shown, the punching mechanism 100 further includes a second guide post 54, which is disposed in one of the first template 21 and the second template 22 and passes through the other of the first template 21 and the second template 22. The second guide post 54 passes through the ejector plate 23 so that the first template 21 and the second template 22 are guided and cooperated.

[0091] The second guide post 54 is disposed in one of the first template 21 and the second template 22 and passes through the other of the first template 21 and the second template 22. That is, the second guide post 54 can be disposed in the first template 21 and pass through the second template 22, or the second guide post 54 can be disposed in the second template 22 and pass through the first template 21. As some embodiments of this application, the second guide post 54 is disposed in the second template 22 and passes through the first template 21 so that the first template 21 and the second template 22 are guided and matched.

[0092] By including a second guide post 54 in the punching mechanism 100, the movement of the first template 21 can be guided, so that the movement direction of the first punch 313 is accurate, reducing the risk of the first punch 313 moving off-center, which helps to improve the reliability of the punching mechanism 100.

[0093] As some embodiments of this application, such as Figure 5 , Figure 8 As shown, the punching mechanism 100 further includes: a second guide bushing 55, a second guide post 54 disposed in one of the first template 21 and the second template 22, the second guide bushing 55 passing through the other of the first template 21 and the second template 22, and the second guide post 54 passing through the second guide bushing 55 and guidingly engaging with the second guide bushing 55, so that the first template 21 and the second template 22 are guidedly engaged. For example, the second guide post 54 is disposed in the first template 21, the second guide bushing 55 passes through the second template 22, and the second guide post 54 passes through the second guide bushing 55 and guidingly engaging with the second guide bushing 55, so that the first template 21 and the second template 22 are guidedly engaged.

[0094] This design improves guiding stability and increases guiding stroke, which in turn enhances the reliability of the punching mechanism 100.

[0095] In some embodiments of this application, such as Figures 1-8 As shown, the drive assembly 60 also includes a mounting plate 62 and two fastening nuts 63. The mounting plate 62 is fixed to the second mold frame 12. The drive rod 61 passes through the mounting plate 62 and has external threads. The two fastening nuts 63 are threadedly engaged with the drive rod 61 and are respectively located on both sides of the mounting plate 62.

[0096] The mounting plate 62 is fixed to the second mold frame 12. The connection between the mounting plate 62 and the second mold frame 12 can be, but is not limited to, welding or bolt connection. As some embodiments of this application, the mounting plate 62 and the second mold frame 12 are connected by bolts. As some embodiments of this application, the mounting plate 62 and the second mold frame 12 are positioned by locating pins and then connected by bolts, which can improve the positioning accuracy of the mounting plate 62.

[0097] The drive rod 61 passes through the mounting plate 62 and has external threads. Two fastening nuts 63 are threadedly engaged with the drive rod 61. The two fastening nuts 63 are located on opposite sides of the mounting plate 62. In some embodiments of this application, the drive rod 61 has external threads, the mounting plate 62 has mounting holes, and the two fastening nuts 63 are threadedly engaged with the drive rod 61. Furthermore, along the first direction (i.e.... Figure 1 (As shown in the X direction), two fastening nuts 63 are respectively disposed on both sides of the mounting plate 62. The drive rod 61 can pass through the mounting hole and drive the first sub-mold 20 to move. The drive rod 61 can be fixed by tightening the fastening nuts 63 to fix the first sub-mold 20.

[0098] As some embodiments of this application, the head of the drive rod 61 on the side away from the punching mechanism 100 is hexagonal, which facilitates the rotation and pushing / pulling of the drive rod 61 with a socket wrench.

[0099] As some embodiments of this application, the number of driving components 60 and the number of first sub-modules 20 are the same and they are arranged in a one-to-one correspondence. Each driving component 60 can drive one first sub-module 20 along a first direction (i.e., Figure 1 Move in the X direction (as shown).

[0100] This setting allows for adjustment of the first sub-mold 20 along the first direction (i.e. Figure 1 After positioning the drive rod 61 in the X direction (as shown), the first sub-die 20 is fixed, thereby reducing the risk of displacement of the first sub-die 20 during the punching process and improving the reliability of the punching mechanism 100.

[0101] In some embodiments of this application, such as Figure 5 and Figure 7 As shown, the second template 22 has a mating groove 121 and a clearance groove 122, along the first direction (i.e. Figure 1 (in the X direction shown), the clearance groove 122 is connected to the mating groove 121 and the end facing away from the mating groove 121 is open. One end of the drive rod 61 is provided with a mating part 611. The drive rod 61 passes through the clearance groove 122 and the mating part 611 is located in the mating groove 121. The mating part 611 can abut against the wall of the mating groove 121 facing the clearance groove 122 and the wall away from the clearance groove 122.

[0102] Among them, the mating groove 121 and the clearance groove 122 are connected and arranged along the first direction (i.e. Figure 1 (in the X direction shown), the clearance groove 122 has one end close to the mating groove 121 and one end away from the mating groove 121, and the end of the clearance groove 122 away from the mating groove 121 is open.

[0103] One end of the drive rod 61 is provided with a mating part 611. The drive rod 61 can pass through the relief groove 122. The mating part 611 is located in the mating groove 121. The mating part 611 can abut against the wall of the mating groove 121 facing the relief groove 122, so that the wall of the mating groove 121 facing the relief groove 122 serves as the force point of the first sub-mold 20. Moreover, the mating part 611 can abut against the wall of the mating groove 121 away from the relief groove 122, so that the wall of the mating groove 121 away from the relief groove 122 serves as the force point of the first sub-mold 20, thereby driving the first sub-mold 20 to move.

[0104] As some embodiments of this application, the ejector plate 23 has a clearance notch 231 with the same structure as the mating groove 121 and the clearance groove 122. During assembly, the ejector plate 23 can be assembled with the second template 22 by bolt connection first, and then the drive rod 61 is driven along the height direction of the punching mechanism 100 (i.e., Figure 1 (As shown in the Z direction) passes through the clearance notch 231 of the ejector plate 23, so that the mating part 611 mates with the mating groove 121 of the second template 22.

[0105] This arrangement facilitates the assembly of the drive rod 61 with the first sub-mold 20, reduces the installation difficulty of the drive rod 61, and improves the assembly efficiency of the punching mechanism 100.

[0106] As some embodiments of this application, the pad 53 has a clearance hole, which communicates with and has the same shape as the clearance notch 231. The clearance hole is also connected to the mating groove 121 and the clearance groove 122. The drive rod 61 can move along the height direction of the punching mechanism 100 (i.e., Figure 1 The Z-direction shown passes sequentially through the clearance notch 231 of the ejector plate 23 and the clearance hole of the pad plate 53, so that the mating part 611 mates with the mating groove 121 of the second template 22.

[0107] In some embodiments of this application, such as Figure 2 , Figures 4-6 As shown, the punching mechanism 100 also includes a first punching assembly 30, which includes a first insert 31 and a first punch 313. The first insert 31 is disposed on the first template 21, and the first punch 31 is disposed on the first insert 31. The first mold frame 11 can drive the first template 21 along the height direction of the punching mechanism 100 (i.e., Figure 1 The punch 313 moves in the Z direction (as shown) to extend into or out of the feeding space 24, and the punching mechanism 100 moves in the height direction (i.e., the height direction) of the punching mechanism 100. Figure 1 The Z direction shown) and the first direction (i.e. Figure 1 The X direction shown is perpendicular to it;

[0108] The first insert 31 has a first mating hole 311, and a first boss 312 is provided in the first mating hole 311. The first punch 313 passes through the first mating hole 311 and has a second boss 314, along the height direction of the punching mechanism 100 (i.e., Figure 1 (As shown in the Z direction), the first boss 312 is located below the second boss 314 and limits the second boss 314.

[0109] The first punching assembly 30 includes a first insert 31 and a first punch 313. The first insert 31 is disposed on the first template 21. Specifically, the first insert 31 is embedded in the first template 21. As some embodiments of this application, the first template 21 has a first insert groove 76, and the first insert 31 can be embedded in the first insert groove 76 so that the first insert 31 is disposed on the first template 21. The first punch 313 is disposed on the first insert 31. The first punch 313 is disposed on the first insert 31 in a manner that can be, but is not limited to, snap-fit, interference fit, etc. As some embodiments of this application, the first punch 313 and the first insert 31 are engaged by snap-fit.

[0110] The first mold frame 11 can drive the first template 21 along the height direction of the punching mechanism 100 (i.e., Figure 1 The first punch 313 moves in the Z direction (as shown) to extend into or retract from the feeding space 24. As some embodiments of this application, the first die frame 11 can be connected to a hydraulic assembly, which can drive the first die frame 11 along the height direction of the punching mechanism 100 (i.e., in the Z direction). Figure 1 The first template 21 moves along the height direction of the punching mechanism 100 (i.e., the Z direction shown) to move the Z direction, thereby driving the first template 21 along the height direction of the punching mechanism 100 (i.e., the Z direction shown). Figure 1 The first punch 313 moves along the height direction of the punching mechanism 100 (i.e., the Z direction shown) to move the first punch 313 along the height direction of the punching mechanism 100 (i.e., the Z direction shown). Figure 1 The first punch 313 moves in the Z direction (as shown) to extend into or retract from the feeding space 24, thereby punching the strip material in the feeding space 24. As some embodiments of this application, the first die frame 11 can be connected to a drive motor, which can drive the first die frame 11 along the height direction of the punching mechanism 100 (i.e., in the Z direction). Figure 1 The first punch 313 moves in the Z direction (as shown) to extend into or out of the feeding space 24, thereby punching the material strip in the feeding space 24. By setting the ejector plate 23, when the first punch 313 drives the material strip to move upward, the ejector plate 23 can block the material strip so that the material strip is in the feeding space 24.

[0111] This setup allows for adjustment of the punch hole size by replacing the first punching component 30, eliminating the need to remake the entire mold and thus saving on punching costs.

[0112] The number of first mating holes 311 can be multiple, including but not limited to two or three. In some embodiments of this application, the number of first mating holes 311 is two. In some embodiments of this application, the number of first mating holes 311 is two, and the number of first punches 313 is also two. The number of first mating holes 311 and first punches 313 is the same and they are set in a one-to-one correspondence.

[0113] The first mating hole 311 has a first boss 312, and the first punch 313 has a second boss 314. The first punch 313 passes through the first mating hole 311 and extends along the height direction of the punching mechanism 100 (i.e., Figure 1 (as shown in the Z direction), the first boss 312 is located below the second boss 314 and limits the second boss 314. That is to say, the second boss 314 can form a stop and limit with the first boss 312. When the first mold frame 11 is along the height direction of the punching mechanism 100 (i.e., Figure 1 When the Z-direction (as shown) moves upward, it can drive the first template 21 along the height direction of the punching mechanism 100 (i.e., Figure 1 The first template 21 moves upward along the height direction of the punching mechanism 100 (i.e., the Z direction shown), and moves upward along the Z direction. Figure 1 The upward movement of the first mold base 11 (in the Z direction shown) can cause the first insert 31 to move accordingly. When the first insert 31 moves upward, it can drive the second boss 314 to move upward through the first boss 312, thereby driving the first punch 313 to move upward. Furthermore, when the first mold base 11 moves along the height direction of the punching mechanism 100 (i.e., along the Z direction shown), the first insert 31 can move upward. Figure 1 When the Z-direction shown moves downward, it can push the first template 21, the first insert 31, and the first punch 313 downward.

[0114] This arrangement facilitates the assembly of the first insert 31 and the first punch 313, reduces the assembly difficulty of the first punch 313, and enables the first insert 31 to drive the first punch 313 to move upward. The ingenious design reliably drives the first punch 313 to perform punching operations.

[0115] As some embodiments of this application, such as Figure 9 As shown, the first template 21 has a first insert groove 76, the first insert groove 76 has a fifth boss 77, and the first insert 31 is received in the first insert groove 76 and located above the fifth boss 77. That is to say, the fifth boss 77 can form a stop and limit with the first insert 31. When the first mold frame 11 is along the height direction of the punching mechanism 100 (i.e., Figure 1 When the Z-direction (as shown) moves upward, it can drive the first template 21 along the height direction of the punching mechanism 100 (i.e., Figure 1The first template 21 moves upward along the height direction of the punching mechanism 100 (i.e., the Z direction shown). Since the first insert 31 is located above the fifth boss 77 and is stopped and limited by the fifth boss 77, the first template 21 moves upward along the height direction of the punching mechanism 100 (i.e., the Z direction shown). Figure 1 The upward movement of the first mold base 11 (in the Z direction shown) can cause the first insert 31 to move accordingly. When the first insert 31 moves upward, it can drive the second boss 314 to move upward through the first boss 312, thereby driving the first punch 313 to move upward. Furthermore, when the first mold base 11 moves along the height direction of the punching mechanism 100 (i.e., along the Z direction shown), the first insert 31 can move upward. Figure 1 When the Z-direction shown moves downward, it can push the first template 21, the first insert 31, and the first punch 313 downward.

[0116] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, the first punching assembly 30 further includes: a second insert 32 and a third insert 33. The second insert 32 is disposed on the ejector plate 23 and has a second mating hole 321. The third insert 33 is disposed on the second template 22 and has a third mating hole 331. Along the height direction of the punching mechanism 100 (i.e., Figure 1 (As shown in the Z direction), the first mating hole 311, the second mating hole 321, and the third mating hole 331 are directly opposite each other, and the first punch 313 passes through the first mating hole 311, the second mating hole 321, and the third mating hole 331.

[0117] The second insert 32 is mounted on the ejector plate 23. The second insert 32 has a second mating hole 321. The number of the second mating holes 321 can be multiple, and the number of the second mating holes 321 can be, but is not limited to, two or three. As some embodiments of this application, the number of the second mating holes 321 is two.

[0118] The third insert 33 is installed on the second template 22. The third insert 33 has a third mating hole 331. The number of third mating holes 331 can be multiple, and the number of third mating holes 331 can be, but is not limited to, two or three. As some embodiments of this application, the number of third mating holes 331 is two.

[0119] The number of first mating holes 311, second mating holes 321, and third mating holes 331 are the same and they are arranged in a one-to-one correspondence. In some embodiments of this application, the number of first mating holes 311 is two, the number of second mating holes 321 and third mating holes 331 is the same as the number of first mating holes 311 and they are arranged in a one-to-one correspondence. The number of first punches 313 is two, and the two first punches 313 can be respectively inserted into the first mating holes 311, second mating holes 321, and third mating holes 331.

[0120] It should be noted that the ejector plate 23 and the second template 22 can define the feeding space 24. By allowing the first punch 313 to pass through the first mating hole 311, the second mating hole 321, and the third mating hole 331, the first punch 313 can punch holes in the material strip in the feeding space 24. Furthermore, by aligning the first mating hole 311, the second mating hole 321, and the third mating hole 331, the movement of the first punch 313 can be guided, thereby improving the accuracy of the punching and enhancing the reliability of the punching mechanism 100.

[0121] In some embodiments of this application, such as Figure 1 and Figure 2 , Figures 4-7 As shown, the punching mechanism 100 also includes a second sub-mold 70 and a second punch 71. The second sub-mold 70 includes a third template 72 and a fourth template 74. The third template 72 is fixed to the first mold frame 11, the fourth template 74 is fixed to the second mold frame 12, and the second punch 71 is disposed on the third template 72. The first mold frame 11 can drive the third template 72 to move along the height direction of the punching mechanism 100, so as to drive the second punch 71 to move.

[0122] The third template 72 is fixed to the first mold frame 11. The connection between the third template 72 and the first mold frame 11 can be, but is not limited to, snap-fit ​​or bolt connection. As some embodiments of this application, the third template 72 and the first mold frame 11 are connected by bolt connection. The fourth template 74 is fixed to the second mold frame 12. The connection between the fourth template 74 and the second mold frame 12 can be, but is not limited to, snap-fit ​​or bolt connection. As some embodiments of this application, the fourth template 74 and the second mold frame 12 are connected by bolt connection.

[0123] The second punch 71 is disposed on the third template 72. As in some embodiments of this application, the third template 72 has a fourth mating hole 73, and the fourth mating hole 73 has a fourth boss 731. The second punch 71 passes through the fourth mating hole 73 and has the third boss 711, along the height direction of the punching mechanism 100 (i.e., Figure 1 (As shown in the Z direction), the fourth boss 731 is located below the third boss 711 and limits the third boss 711.

[0124] The number of fourth mating holes 73 can be multiple, including but not limited to two or three. In some embodiments of this application, the number of fourth mating holes 73 is two. The fourth template 74 has a fifth mating hole 75, located along the height direction of the punching mechanism 100 (i.e.,...). Figure 1(As shown in the Z direction), the number of fourth mating holes 73 and fifth mating holes 75 are the same and they are directly opposite each other. The number of second punches 71 is the same as the number of fourth mating holes 73 and fifth mating holes 75. The second punches 71 are inserted into the corresponding fourth mating holes 73 and fifth mating holes 75. This arrangement can guide the movement of the second punches 71, improve the accuracy of the second punches 71 in drilling, and help improve the reliability of the punching mechanism 100.

[0125] The first mold frame 11 can drive the third mold plate 72 along the height direction of the punching mechanism 100 (i.e., Figure 1 The third template 72 moves along the height direction of the punching mechanism 100 (i.e., in the Z direction shown), and engages with the third boss 711 via the fourth boss 731. Figure 1 When the first die set 11 moves upward along the height direction of the punching mechanism 100 (i.e., the Z direction shown), it can drive the second punch 71 to move upward, and when the first die set 11 moves upward along the height direction of the punching mechanism 100 (i.e., the Z direction shown), it can drive the second punch 71 to move upward. Figure 1 When the Z-direction (as shown) moves downward, it can push the third template 72 and the second punch 71 downward.

[0126] As some embodiments of this application, the punching mechanism 100 includes two first sub-dies 20, one second sub-die 70, and two drive assemblies 60. The two first sub-dies 20 are aligned along a first direction (i.e., Figure 1 The two first sub-molds 20 (shown in the X direction) are respectively located on both sides of the second sub-mold 70, and the two first sub-molds 20 are relative to the second sub-mold 70 along the first direction (i.e., Figure 1 The X-direction shown is movable, and the two drive components 60 correspond one-to-one with the two first sub-modules 20.

[0127] This configuration makes the punching mechanism 100 structurally sound. By adjusting the position of the first die 20, the position of the first punch 313 can be adjusted along the first direction, allowing the punching mechanism 100 to adapt to different products, improving its versatility and reducing production costs. Furthermore, it allows for the punching of multiple holes on the strip at once, which improves punching efficiency.

[0128] As some embodiments of this application, such as Figure 8 As shown, the mold frame 10 also includes a third mold frame 13, which is disposed between the first mold frame 11 and the second mold frame 12 and fixed to the second mold frame 12. The third mold frame 13 has a direction along the second direction (i.e., Figure 1 The groove extends in the Y direction (as shown), and the second punch 71 can pass through the groove. This arrangement can guide the movement of the second punch 71, improve the punching accuracy of the second punch 71, and help improve the reliability of the punching mechanism 100.
