They can precisely control the punching gap to ensure cut quality and are suitable for finishing automotive body panels, forging burrs, or injection molding flash.
[0003] The cutting component of the cutting die is used to cut off the excess edge material of the workpiece. In related technologies, when the workpiece is a heat sink, the upper die is prone to damage to the fins of the heat sink during the mold closing process with the lower die. Utility Model Content
[0004] This application discloses a trimming component and a trimming die to solve the technical problem that the trimming process of workpieces in related technologies is prone to damage.
[0005] To solve the above problems, the present invention adopts the following technical solution:
[0006] In a first aspect, this application discloses a cutting assembly for a cutting die, comprising:
[0007] A first abutting structure is provided on the upper mold; the first abutting structure has a cavity for accommodating the workpiece;
[0008] The second abutment structure is located in the lower mold and is used to place the workpiece;
[0009] The cutting tool is positioned on the upper mold and surrounds the first abutment structure;
[0010] The deformable part is disposed inside the cavity and has a gap between it and the inner wall of the cavity;
[0011] During the process of closing the upper and lower molds, the top of the workpiece comes into contact with the deformable part, causing the deformable part to deform and fill the gap in the workpiece.
[0012] In some designs, the deformable component includes a deformable part and a mounting block;
[0013] The mounting block is detachably installed inside the cavity, and the deformable part is located at the bottom of the mounting block, with a gap between it and the inner wall of the cavity.
[0014] In some designs, the second abutting structure is provided with a positioning part corresponding to the geometric features of the workpiece, so as to position the workpiece at the location of the second abutting structure.
[0015] In some designs, the first abutting structure is slidably connected to the upper mold along the height direction of the upper mold and can move between a first position and a second position;
[0016] During the process of the upper and lower molds closing, the first abutting structure moves from the first position to the second position.
[0017] In some designs, the top of the first abutting structure is provided with a first guide post, and the first abutting structure is slidably connected to the upper mold through the first guide post.
[0018] In some designs, a connecting plate is provided at the top of the first guide post, and the connecting plate is connected to the upper mold through a first elastic element.
[0019] In some designs, the upper mold is equipped with a second guide post, and the connecting plate is slidably connected to the upper mold through the second guide post;
[0020] The first elastic element is fitted onto the second guide post.
[0021] In some designs, the cutting assembly of the cutting die also includes a buffer, which is positioned on the lower die corresponding to the part of the workpiece to be cut.

[0023] Secondly, this application also discloses a cutting die, including a cutting component of the cutting die.
[0024] The technical solution adopted in this utility model can achieve the following beneficial effects:
[0025] The cutting assembly of the cutting die of this application, when shearing a workpiece, places the workpiece on top of the lower die. After the upper and lower dies close, the first abutting structure abuts against the workpiece, forcing the workpiece into a stable stress state before cutting, effectively suppressing elastic slippage and stress release during the shearing process. After the upper and lower dies close, under the pressure of the upper die, the cutter arranged around the first abutting structure cuts the workpiece located outside the first and second abutting structures to remove excess parts of the workpiece. Furthermore, during the closing process of the upper and lower dies, the deformable component adaptively fills the gaps (gap between fins) of the workpiece using its compressive deformation and makes soft contact with the workpiece, significantly reducing the risk of hard contact, uniformly distributing pressure to protect the integrity of the thin-walled fins, thereby protecting the workpiece and reducing the probability of workpiece damage.

[0043] During the process of trimming the edges of a radiator, the inventor discovered that because the radiator has multiple fins, which are numerous, thin, and have a certain gap between adjacent fins, the upper mold will make hard contact with the fins during trimming. If the mold closing force is too large, it can easily cause scratches or bending of the fins.
[0044] The following is in conjunction with the appendix Figures 1 to 6 The present application provides a detailed description of the edge trimming component and edge trimming mold through specific embodiments and application scenarios.
[0045] Some embodiments of this application disclose a cutting assembly for a cutting die, including a first abutment structure 210, a second abutment structure 110, a cutting tool 300, a deformable part 600, and a buffer part 400.
[0046] like Figure 1 and Figure 4 As shown, the first abutting structure 210 is disposed on the upper mold 200, and the second abutting structure 110 is disposed on the lower mold 100; the workpiece 500 is placed on the top of the lower mold 100. After the upper mold 200 and the lower mold 100 are closed, the first abutting structure 210 abuts against the workpiece 500, forcing the workpiece 500 to enter a stable stress state before cutting, effectively suppressing elastic slippage and stress release during the shearing process.
[0047] It should be noted that in this embodiment, workpiece 500 is a heat sink, such as... Figure 7 As shown, the same applies below.
[0048] In this embodiment, there can be multiple first abutting structures 210 and second abutting structures 110, which can be flexibly set according to actual usage requirements. This embodiment does not limit this.
[0049] like Figure 1 , Figure 3 and Figure 4 As shown, the cutting tool 300 is disposed on the upper mold 200 and surrounds the first abutment structure 210. The cutting tool 300 is used to cut off the excess part of the workpiece 500. After the upper mold 200 and the lower mold 100 are closed, under the pressure of the upper mold 200, the cutting tool 300 disposed around the first abutment structure 210 cuts the workpiece 500 located outside the first abutment structure 210 and the second abutment structure 110 to cut off the excess part of the workpiece 500.
[0050] like Figure 4 and Figure 6 As shown, the first abutment structure 210 has a cavity 220 for accommodating the workpiece 500. During the mold closing process of the upper mold 200 and the lower mold 100, the cavity 220 is used to accommodate the workpiece 500 so that the cutter 300 can cut off the excess part of the workpiece 500.
[0051] like Figure 5 and Figure 6 As shown, the deformable part 600 is disposed within the cavity 220. During the mold closing process of the upper mold 200 and the lower mold 100, the top of the workpiece 500 contacts the deformable part 600, causing the deformable part 600 to deform and fill the gap 230 of the workpiece 500. By disposing of the deformable part 600 within the cavity 220, during the mold closing process of the upper mold 200 and the lower mold 100, the deformable part 600 adaptively fills the gap 230 (the gap between the fins) of the workpiece 500 using its compressive deformation, and makes soft contact with the workpiece 500, significantly reducing the risk of hard contact, uniformly distributing pressure to protect the integrity of the thin-walled fins, thereby protecting the workpiece 500 and reducing the probability of damage to the workpiece 500.
[0052] like Figure 6 As shown, there is a gap 230 between the deformable part 600 and the inner wall of the cavity 220. By setting a reasonable gap 230 between the deformable part 600 and the inner wall of the cavity 220, deformation space is reserved for the thermal expansion and lateral extension of the deformable part 600 under pressure, and the assembly accuracy requirements are reduced, making maintenance and replacement easier.
[0053] like Figure 5 and Figure 6As shown, the deformable part 600 includes a deformable portion and a mounting block 610. The mounting block 610 is detachably disposed within the cavity 220, and the deformable portion is disposed at the bottom of the mounting block 610, with a gap 230 between it and the inner wall of the cavity 220. By detachably disposing of the mounting block 610 within the cavity 220, the deformable portion can be quickly replaced by removing the mounting block 610 when needed. The gap 230 between the deformable portion and the inner wall of the cavity 220 provides space for the deformable portion's thermal expansion and lateral extension under pressure, while also reducing assembly precision requirements and facilitating maintenance and replacement.
[0054] In this embodiment, the deformable part can be memory foam, memory rubber or other materials, and can be flexibly selected according to the usage requirements. This embodiment does not limit this.
[0055] like Figure 5 As shown, the second abutment structure 110 has a positioning part 120 corresponding to the geometric features of the workpiece 500 to position the workpiece 500 within the second abutment structure 110. By precisely matching the geometric features of the workpiece 500 with the positioning part 120 of the second abutment structure 110, the placement of the workpiece 500 is ensured to be strictly aligned with the pressure area of the deformation part. This ensures that the deformation of the deformation part is well-matched to the height distribution of the gap 230 between the workpiece 500 and the mold during mold closing. This avoids local overload caused by positioning deviations and ensures more uniform deformation filling, ultimately improving the support stability of the workpiece 500. This is suitable for machining complex contour workpieces 500. Furthermore, the cooperation between the positioning part 120 and the workpiece 500 increases the lateral constraint on the workpiece 500, thereby improving stability during the shearing process of the workpiece 500.
[0056] In this embodiment, the top of the workpiece 500 has a groove structure, and the positioning part 120 is a protrusion corresponding to the groove structure.
[0057] like Figure 1 and Figure 4 As shown, the first abutting structure 210 is slidably connected to the upper mold 200 along the height direction of the upper mold 200, and can move between a first position and a second position; during the mold closing process of the upper mold 200 and the lower mold 100, the first abutting structure 210 moves from the first position to the second position. The first abutting structure 210, through its sliding connection along the height direction of the upper mold 200, moves from the first position to the second position during mold closing, achieving dynamic adjustment of the contact pressure. This allows the deformable part 600 to flexibly abut against the workpiece 500 in the initial stage of mold closing, avoiding hard impact, and provides stable support for the workpiece 500 in the final pressing stage, thereby protecting the workpiece 500 while ensuring cutting accuracy.
[0058] like Figure 4As shown, the top of the first abutting structure 210 is provided with a first guide post 240, and the first abutting structure 210 is slidably connected to the upper mold 200 through the first guide post 240. The first guide post 240 on the top of the first abutting structure 210 and its slidable connection with the upper mold 200 guide the movement of the first abutting structure 210 in the height direction, ensuring that the first abutting structure 210 slides smoothly.
[0059] Correspondingly, the upper mold 200 has a guide hole, and the first guide post 240 is slidably disposed in the guide hole to realize the sliding connection between the first abutting structure 210 and the upper mold 200.
[0060] In this embodiment, multiple first guide posts 240 can be provided to further increase the smoothness of the sliding of the first abutment structure 210. It should be noted that the number of first guide posts 240 can be flexibly set according to actual usage requirements, and this embodiment does not limit this.
[0061] like Figure 1 and Figure 4 As shown, a connecting plate 250 is provided at the top of the first guide post 240, and the connecting plate 250 is connected to the upper mold 200 through a first elastic member 270. When the upper mold 200 and the lower mold 100 are closed, during the process of the first abutting structure 210 moving from the first position to the second position, the connecting plate 250 compresses the first elastic member 270, and the first elastic member 270 stores elastic potential energy; after the upper mold 200 and the lower mold 100 are separated, the first elastic member 270 releases the elastic potential energy, causing the first abutting structure 210 to move from the second position to the first position.
[0062] In this embodiment, there are multiple first elastic elements 270, which can be flexibly set according to actual usage requirements. This embodiment does not limit this.
[0063] In this embodiment, the first elastic element 270 is preferably a spring.
[0064] like Figure 1 and Figure 4 As shown, the upper mold 200 is provided with a second guide post 260, and the connecting plate 250 is slidably fitted to the second guide post 260. By setting the second guide post 260 in the upper mold 200, the connecting plate 250 is kept horizontal during the up and down movement, eliminating the problem of asynchronous movement of multiple first guide posts 240 caused by the tilt of the connecting plate 250.
[0065] like Figure 1 and Figure 4 As shown, the first elastic element 270 is sleeved on the second guide post 260. By sleeved on the second guide post 260, the stress concentration caused by the eccentric compression of the spring is reduced, the risk of fatigue fracture is lowered, and the service life of the first elastic element 270 is increased.
[0066] like Figure 1 and Figure 2 As shown, the cutting assembly of the cutting die also includes a buffer 400, which is disposed on the lower die 100 corresponding to the part 510 of the workpiece 500 to be cut. During the closing process of the upper die 200 and the lower die 100, the part 510 of the workpiece 500 to be cut comes into contact with the buffer 400. When the cutter 300 cuts the excess part of the workpiece 500, the part 510 of the workpiece 500 to be cut is prone to splashing due to shearing force. Therefore, by providing the buffer 400 on the lower die 100, the part 510 of the workpiece 500 to be cut comes into contact with the buffer 400 during the cutting process, so as to avoid the workpiece 500 from splashing.
[0067] In this embodiment, there can be multiple buffers 400, which can be flexibly set according to usage requirements. This embodiment does not limit this.
[0068] like Figure 2 As shown, the buffer 400 includes a push rod 410 and a second elastic element 420. The push rod 410 is slidably connected to the lower mold 100 along the height direction of the lower mold 100, and the push rod 410 is connected to the lower mold 100 through the second elastic element 420. During the mold closing process of the upper mold 200 and the lower mold 100, the cut portion 510 of the workpiece 500 contacts the top of the push rod 410. During the cutting process of the workpiece 500 by the cutter 300, the cut portion 510 of the workpiece 500 contacts the push rod 410 under the action of the shearing force of the cutter 300, causing the push rod 410 to move downward. During the downward movement, the push rod 410 compresses the second elastic element 420, thereby buffering the shearing force of the cut portion 510 of the workpiece 500 and preventing the cut portion 510 of the workpiece 500 from splashing.
[0069] Some embodiments of this application also disclose a trimming die, such as Figure 1 , Figure 3 and Figure 4 As shown, a cutting assembly including a cutting die is included.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0071] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved.
