[0040] This utility model proposes a terminal cutting device 1000.

[0041] Please see Figures 1 to 2 In one embodiment of this utility model, the terminal cutting device 1000 proposed by this utility model includes a mounting frame 1, a lifting mechanism 2, a cutting mechanism 3, and a platform 4. The lifting mechanism 2 is connected to the mounting frame 1; the cutting mechanism 3 is connected to the lifting mechanism 2 and has a cutting head 33; the platform 4 is connected to the mounting frame 1 and has a material hole 4a adapted to the cutting head 33; wherein, the lifting mechanism 2 is used to drive the cutting mechanism 3 to approach or move away from the platform 4, so that the cutting head 33 extends into or away from the material hole 4a.

[0042] In this embodiment, during the cutting operation, the terminal block is placed on the platform 4 with the terminals aligned with the material holes 4a. The lifting mechanism 2 moves the cutting mechanism 3 closer to the platform 4, and the cutting head 33 extends into the material hole 4a. The cutting head 33 cuts the terminal block against the periphery of the material hole 4a, causing the terminals to separate from the frame and fall from the material hole 4a. Then, the lifting mechanism 2 moves the cutting mechanism 3 away from the platform 4, allowing a new terminal block to be cut for the next round of cutting. This allows for the simultaneous cutting of multiple terminals on the terminal block, improving terminal production efficiency.

[0043] Specifically, the mounting frame 1 includes a base 11 and a cantilever 12. The base 11 serves as the mounting foundation for the entire device and adopts a plate-like structure. The cantilever 12 is inverted L-shaped, meaning it includes a horizontal section and a vertical section. The vertical section is connected to the top of the base 11, and the connection between the cantilever 12 and the base 11 can be achieved through welding or bolting. The lifting mechanism 2 can be driven by a servo motor or cylinder, and is installed at the end of the cantilever 12 furthest from the base 11, i.e., on the horizontal section. The cutting mechanism 3 is connected to the lifting mechanism 2, and the platform 4 is installed on the base 11 at a position corresponding to the cutting mechanism 3, so that the platform 4 is located on the path through which the lifting mechanism 2 drives the cutting mechanism 3 to move up and down. Due to the inverted L-shaped cantilever 12, the platform 4 is positioned below the horizontal section of the cantilever 12, which avoids the cantilever 12 obstructing the platform 4 and causing adverse effects on the loading operation. The cutting mechanism 3 has a cutter head 33, and the stage 4 has material holes 4a adapted to the cutter head 33. The shape of the material holes 4a is adapted to the shape of the cutter head 33 so that the cutter head 33 can be inserted. Each material hole 4a is located on the movement trajectory of a cutter head 33, ensuring that the periphery of the material hole 4a can cooperate with the cutter head 33 to cut the terminal block. The cutter head 33 can be made of cemented carbide material, which has high strength and wear resistance, ensuring cutting accuracy and service life.

[0044] The terminal cutting device 1000 provided in this embodiment can simultaneously cut multiple terminals on a terminal block, greatly improving production efficiency compared to traditional manual cutting methods. By using a servo motor or cylinder to drive the lifting mechanism 2, which in turn moves the cutting mechanism 3, automated control of the cutting process is achieved, reducing manual labor intensity. In summary, the terminal cutting device 1000 provided in this embodiment effectively improves terminal production efficiency, reduces manual labor intensity, and has good economic and social benefits.

[0045] Further, please refer to Figures 4 to 8 In one embodiment of the present invention, the cutting mechanism 3 further includes a first clamping member 31 and a second clamping member 32. The first clamping member 31 is connected to the lifting mechanism 2 and is detachably connected to the second clamping member 32. The side of the first clamping member 31 facing the second clamping member 32 is provided with a blind mounting hole 31a, and the second clamping member 32 is provided with a through mounting hole 32a. The side wall of the cutting head 33 is provided with a limiting protrusion 332. One end of the cutting head 33 is inserted into the inner wall of the blind mounting hole 31a, and the other end of the cutting head 33 passes through the through mounting hole 32a through the second clamping member 32 and is provided with a cutting edge 331. The limiting protrusion 332 is clamped between the first clamping member 31 and the second clamping member 32.

[0046] In this embodiment, the cutting mechanism 3 further includes a first clamping member 31 and a second clamping member 32. The first clamping member 31 is connected to the lifting mechanism 2 and detachably connected to the second clamping member 32. The first clamping member 31 and the lifting mechanism 2 can be fixedly connected by welding or other methods, or detachably connected by threads or bolts to improve maintenance convenience. To achieve locking and detachable connection between the first clamping member 31 and the second clamping member 32, multiple holes for threading screws are provided on the first clamping member 31 and the second clamping member 32, and locking is achieved by screws. It should be noted that, to improve the readability of other structures, the holes for threading locking screws and the locking screws on the first clamping member 31 and the second clamping member 32 are not shown in the accompanying drawings. The second clamping member 32 and the second clamping member 32 can adopt a rectangular block structure. It is understood that the shapes of the second clamping member 32 and the second clamping member 32 can be...

[0047] To achieve the mounting and limiting of the cutting head 33 on the first clamping member 31 and the second clamping member 32, a blind mounting hole 31a is provided on the side of the first clamping member 31 facing the second clamping member 32, and a through mounting hole 32a is provided on the second clamping member 32. One end of the cutting head 33 is inserted into the inner wall of the blind mounting hole 31a, and the other end of the cutting head 33 passes through the through mounting hole 32a through the second clamping member 32 and has a cutting edge 331, thus achieving radial limiting of the cutting head 33. A limiting protrusion 332 is provided on the side wall of the cutting head 33, and the limiting protrusion 332 is clamped between the first clamping member 31 and the second clamping member 32, achieving radial limiting of the cutting head 33. Furthermore, the shape of the cutting head 33 can also be set to square, rectangular, or other shapes to prevent the cutting head 33 from rotating. Taking a square cutter head 33 as an example, when setting a cutting edge 331 on the square cutter head 33, a square opening can be set at the end of the cutter head 33 facing the stage 4, and the cutting edge 331 can be formed by trimming, grinding, quenching and other processes around the square opening. The cutting edge 331 can be set in a U-shape, so multiple terminals can be set on the four sides of the frame hole of the terminal block. The U-shaped cutting edge 331 can cut the terminals on the four sides in one punch, which improves production efficiency.

[0048] Further, please refer to Figure 6 In one embodiment of the present invention, the second clamping member 32 is provided with a limiting groove 32b on the side facing the first clamping member 31. The limiting groove 32b is connected to the mounting through hole 32a. The limiting protrusion 332 is accommodated in the limiting groove 32b and engages with the inner wall of the limiting groove 32b.

[0049] In this embodiment, considering that after the first clamping member 31 and the second clamping member 32 clamp the limiting protrusion 332, a gap is formed between the first clamping member 31 and the second clamping member 32, which is not conducive to the fit of the end faces of the first clamping member 31 and the second clamping member 32. Under long-term continuous impact, the existence of the gap makes the structure prone to deformation and wear, thus causing positioning deviation. Furthermore, stress concentration is prone to occur at the limiting protrusion 332, affecting the service life of the cutter head 33 and the clamping members. Therefore, in this embodiment, a limiting groove 32b is provided on the side of the second clamping member 32 facing the first clamping member 31. The limiting groove 32b is connected to the mounting through hole 32a. The limiting protrusion 332 is accommodated in the limiting groove 32b and engages with the inner wall of the limiting groove 32b. When the first clamping member 31 and the second clamping member 32 are locked together, the end faces of the two clamping members can fit together to eliminate gaps, optimize the structural stress, reduce stress concentration, and the engagement of the limiting protrusion 332 with the inner wall of the limiting groove 32b can limit the cutting head 33, reduce the radial rotation and movement of the cutting head 33, and improve the installation accuracy of the cutting head 33.

[0050] Further, please refer to Figure 4 and Figure 6 In one embodiment of the present invention, the cutting mechanism 3 includes a plurality of blades 33, each blade 33 being connected to a first clamping member 31 and a second clamping member 32 respectively; or, the cutting mechanism 3 includes a plurality of blades 33, the plurality of blades 33 being connected in sequence and connected to the first clamping member 31 and the second clamping member 32.

[0051] In this embodiment, two methods of setting the cutting head 33 are provided. The first method sets each cutting head 33 as a separate unit, where each cutting head 33 is an independent unit. Each cutting head 33 is inserted into a blind mounting hole 31a on the first clamping member 31 and into a corresponding through mounting hole 32a on the second clamping member 32. This allows each cutting head 33 to be replaced individually, facilitating maintenance. The second method sets each cutting head 33 as a single unit, improving the overall rigidity, deformation resistance, and impact resistance of the cutting head 33. Therefore, it can withstand greater impacts, is more suitable for long-term continuous machining operations, and is more convenient and quick to load and unload. Multiple cutting heads 33 can be set as a single molded structure arranged linearly, with a connecting portion formed between every two cutting heads 33. A clearance groove 32c is provided on the side of the second clamping member 32 facing the first clamping member 31 to accommodate the connecting portion.

[0052] Further, please refer to Figure 4In one embodiment of this utility model, the terminal cutting device 1000 further includes a buffer cleaning mechanism 5, which includes a buffer member 51 and a spring 52. The buffer member 51 is located on the side of the cutting mechanism 3 facing the platform 4 and is slidably connected to the cutting mechanism 3. The buffer member 51 is provided with a cutter head through hole 51a that is adapted to the cutter head 33. The spring 52 connects the buffer member 51 and the cutting mechanism 3. When the spring 52 is in a free state, the cutter head 33 extends into the cutter head through hole 51a.

[0053] In this embodiment, the buffer cleaning mechanism 5 serves both a buffering and cleaning function. On one hand, the buffer member 51 and the spring 52 can absorb part of the impact force through their own structure and the elasticity of the spring 52, preventing the cutting mechanism 3 and the lifting mechanism 2 from being directly damaged by hard impact. On the other hand, the cutter head 33 extends into the cutter head through hole 51a of the buffer member 51. When punching the terminal block, the buffer member 51 abuts against the platform 4, compresses the spring 52, and moves closer to the second clamping member 32. The cutter head 33 passes through the buffer member 51 and is exposed to cut the terminal block. The scrap material such as the frame after the terminals are cut off is easy to stick to the cutter head 33. When the lifting mechanism moves the cutting mechanism 3 away from the platform 4, under the action of the elasticity of the spring 52, the spring 52 gradually returns from the compressed state to the free state. The buffer member 51 gradually moves away from the second clamping member 32 and pushes the frame off the cutter head 33. Understandably, when the spring 52 is not subjected to external force, it is in a free state; when the spring 52 is subjected to axial pressure, it is in a compressed state; and when the spring 52 is subjected to axial tension, it is in a stretched state.

[0054] Specifically, the buffer 51 can be made of high-strength wear-resistant materials, such as tungsten steel or alloy tool steel (e.g., SKD61, SKD11). A first spring hole 32d is provided on the side of the second clamping member 32 facing the buffer 51, and a second spring hole 51b is provided on the side of the buffer 51 facing the second clamping member 32. The two ends of the spring 52 are respectively inserted into the first spring hole 32d and the second spring hole 51b to achieve limiting. The buffer 51 can be slidably connected to the cutting mechanism 3 via a slide rail or slide rod 53 to guide and limit the sliding path of the buffer 51 relative to the cutting mechanism 3, preventing interference and collision between the buffer 51 and the cutter head 33, thus avoiding damage.

[0055] Further, please refer to Figure 4 In one embodiment of the present invention, the buffer cleaning mechanism 5 further includes a slide rod 53, one end of which is connected to the buffer member 51, and the other end of which is provided with a boss 531; the slide rod 53 slides through the cutting mechanism 3, and the cutting mechanism 3 is limited between the boss 531 and the buffer member 51; when the spring 52 is in a free state, the distance between the cutting mechanism 3 and the buffer member 51 reaches its maximum.

[0056] In this embodiment, in order to guide and limit the sliding path of the buffer 51 relative to the cutting mechanism 3 and avoid interference and collision between the buffer 51 and the cutter head 33 causing damage, the buffer cleaning mechanism 5 of this embodiment also includes a slide rod 53. Specifically, one end of the slide rod 53 is provided with a thread, and the other end of the slide rod 53 is provided with a boss 531. The side of the buffer 51 facing the second clamping member 32 is provided with a threaded hole. The first clamping member 31 and the second clamping member 32 are provided with through holes. The threaded end of the slide rod 53 passes through the first clamping member 31 and the second clamping member 32 in sequence and is screwed into the threaded hole. The slide rod 53 is slidably connected to the first clamping member 31 and the second clamping member 32, and the first clamping member 31 and the second clamping member 32 are limited to the boss 531 and the buffer 51. Furthermore, the length of the slide bar 53 can be precisely controlled. When the spring 52 is in a free state, the distance between the cutting mechanism 3 and the buffer 51 reaches its maximum, so as to ensure that when the spring 52 is in a free state, the cutter head 33 can retract into the cutter head through hole 51a on the buffer 51, so as to ensure that the buffer 51 can push off the edge scraps such as the frame of the terminal block that are stuck to the cutter head 33 under the action of the spring force of the spring 52.

[0057] Further, please refer to Figure 9 In one embodiment of this utility model, the platform 4 includes a base 42, two support members 43, and a table surface 44. The table surface 44 is provided with a material hole 4a. The base 42 is connected to the mounting frame 1. The two support members 43 are spaced apart on the base 42. The table surface 44 is located on the side of the support members 43 facing away from the base 42. The table surface 44 connects the two support members 43. The base 42, the two support members 43, and the table surface 44 enclose a material collection space 4b. A receiving tray 6 is slidably provided in the material collection space 4b.

[0058] In this embodiment, to facilitate the collection of the terminals obtained after cutting, the platform 4 integrates a movable receiving tray 6. Specifically, the base 42, serving as the mounting foundation for the platform 4, can be a block structure made of high-strength steel. Two support members 43 are respectively located at both ends of the base 42. The support members 43 can be columnar or block-shaped structures, the purpose of which is to increase the distance between the platform 44 and the base 42 so that the receiving tray 6 can be set between the platform 44 and the base 42. The platform 44 is provided with a material hole 4a. Since the platform 44 needs to cooperate with the cutter head 33 for shearing and is subjected to the impact of the buffer member 51, the platform 44 can be made of a high-hardness, wear-resistant, and impact-resistant material, such as SKD11, Cr12MoV, tungsten steel, etc. The base 42, the two support members 43 and the table surface 44 enclose a material collection space 4b. The receiving tray 6 can be placed in the material collection space 4b by means of a guide rail or slide in contact with the bottom wall of the material collection space 4b, so as to be removed and replaced.

[0059] Further, please refer to Figures 9 to 10In one embodiment of the present invention, a positioning groove 44a is provided on the side of the table surface 44 facing away from the base 42, and a material hole 4a is provided on the bottom wall of the positioning groove 44a. The positioning groove 44a is used to position the terminal block on the table surface 44.

[0060] In this embodiment, to further limit the terminal block and prevent it from shifting during punching and affecting punching accuracy, a positioning groove 44a is provided on the side of the table 44 facing away from the base 42. A material hole 4a is provided on the bottom wall of the positioning groove 44a, and the shape of the positioning groove 44a is adapted to the shape of the terminal block. Thus, the edge of the terminal block can be locked into the positioning groove 44a for limiting, and when the terminal block is placed on the table 44, it can be quickly positioned by the engagement of the edge with the positioning hole, ensuring that the terminal corresponds to the material hole 4a, thereby improving production efficiency.

[0061] Further, please refer to Figure 1 , Figure 2 and Figure 9 In one embodiment of this utility model, a guide post 41 is provided on the platform 4. The guide post 41 extends along the direction from the platform 4 to the cutting mechanism 3. The cutting mechanism 3 is provided with a guide hole 3a. The guide post 41 extends into the guide hole 3a and slides in connection with the inner wall of the guide hole 3a.

[0062] In this embodiment, in order to improve the punching accuracy and ensure that the cutter head 33 is precisely aligned with the material hole 4a, a guide post 41 is provided on the platform 4. The extension direction of the guide post 41 is consistent with the direction in which the lifting mechanism 2 drives the cutting mechanism 3 to move. That is, the guide post 41 extends along the direction from the platform 4 to the cutting mechanism 3. The cutting mechanism 3 is slidably connected to the guide post 41. When the lifting mechanism 2 drives the cutting mechanism 3 to move, the cutting mechanism 3 slides along the guide post 41 and the cutter head 33 is precisely inserted into the material hole 4a.

[0063] For example, the guide post 41 can be fixedly connected to the base 42, such as by welding or by using an integral molding process. The guide post 41 extends through the support member 43 and the table surface 44 in sequence. The buffer member 51, the second clamping member 32 and the first clamping member 31 are provided with coaxial and sequentially connected guide holes 3a. Through the guide holes 3a, the guide post 41 can be inserted into the buffer member 51, the second clamping member 32 and the first clamping member 31 in sequence, and slidably connected with the buffer member 51, the second clamping member 32 and the first clamping member 31 respectively.

[0064] Further, please refer to Figure 2 and Figure 3In one embodiment of the present invention, the lifting mechanism 2 includes a drive motor 21 and a lifting rod 22. The drive motor 21 is mounted on the mounting frame 1 and is connected to the lifting rod 22. One end of the lifting rod 22 is provided with a connecting hole 22a. The cutting mechanism 3 is provided with a fixing protrusion 311, which extends into the connecting hole 22a and is detachably connected to the inner wall of the connecting hole 22a.

[0065] In this embodiment, a through hole aligned with the direction of the lifting rod 22 is provided on the straight section of the cantilever 12. The drive motor 21 is mounted on the top of the horizontal section of the cantilever 12 by bolts or the like, and the lifting rod 22 passes through the through hole. The platform 4 is located directly below the through hole. The drive motor 21 can be a servo motor or a cylinder, etc. The drive motor 21 is connected to the lifting rod 22 for transmission, and the drive motor 21 can drive the lifting rod 22 to move closer to or away from the platform 4. This embodiment also provides two series-connected control switches 7, which are connected to the drive motor 21 to control the activation of the drive motor 21. When both control switches 7 are pressed simultaneously, the drive motor 21 drives the lifting rod 22 to move towards the platform 4, and then drives the lifting rod 22 away from the platform 4 in the opposite direction, corresponding to one punching action. To perform the next punching action, both control switches 7 need to be pressed simultaneously again. This can prevent accidental switch activation that could cause incorrect punching actions, leading to danger or product damage.

[0066] A connecting hole 22a is provided on the end face of the lifting rod 22 away from the drive motor 21. The inner wall of the connecting hole 22a has a through hole with internal threads. The side of the first clamping member 31 facing away from the second clamping member 32 has a protrusion that matches the shape of the connecting hole 22a. This protrusion can extend into the connecting hole 22a and be locked to the lifting rod 22 by setting a bolt in the through hole with internal threads. Furthermore, a groove can be provided on the protrusion, and the bottom wall of the groove is flat so that the bottom wall of the groove abuts more firmly against the end face of the bolt. Optionally, an external thread can be provided on the outer peripheral wall of the protrusion, and a matching internal thread can be provided in the connecting hole 22a, so that the protrusion is directly screwed to the inner wall of the connecting hole 22a. In this embodiment, by detachably connecting the fixing protrusion 311 to the inner wall of the connecting hole 22a, the drive motor 21 or the cutting mechanism 3 can be quickly replaced when it malfunctions, avoiding the impact on production efficiency.
