UTILITY MODEL CONTENT

[0004] In order to overcome the defects of the prior art, the utility model provides a cutting device, which solves the technical problems of large manual operation workload, high labor intensity and low cutting efficiency in the segmented cutting and polishing process of metal bars.

[0005] In order to achieve the above object, the utility model is realized through the following technical scheme: a cutting device is used for segmented cutting and polishing of metal bars, and comprises a workbench corresponding to the feeding direction of the metal bars, and the workbench is sequentially provided with:

[0007] A polishing mechanism is used for polishing the outer surface of the metal bars.

[0008] A cutting mechanism is used for cutting the polished metal bars to a preset length.

[0009] A collecting assembly is used for collecting the cut metal bars.

[0010] Based on the above structure, the principle of the cutting device is that first, the operator places the metal bar in a specific feeding position of the feeding mechanism, starts the feeding mechanism, and the metal bar moves along the set track towards the polishing mechanism at a stable speed; then, when the metal bar enters the polishing mechanism area, the driving device of the polishing mechanism starts to remove the impurities on the surface of the metal bar, and the outer surface of the metal bar is polished by the polishing parts of the polishing mechanism during continuous conveying; then, the polished metal bar continues to convey forward to the cutting mechanism, which can cut the polished metal bar according to the preset length, realizing segmented processing of the metal bar and meeting the specific needs of different metal bar lengths; finally, the material collecting assembly collects the cut metal bar, so that the processed metal bar can be effectively arranged and stored, facilitating subsequent handling and use; the cutting device integrates multiple functional modules such as feeding, polishing, cutting and material collecting, and can realize automatic segmented cutting and polishing of the metal bar, reducing the workload and labor intensity of manual operation, improving the production cutting efficiency, and the metal bar can pass through the feeding, polishing, cutting and material collecting on the workbench in turn, realizing continuous and uninterrupted processing and further improving the production cutting efficiency.

[0011] Furthermore, in this application, a cutting device includes a feeding mechanism comprising: a loading platform, a mounting vertical plate, a first driving device, an adjusting component, and a pair of conveyor belts. The mounting vertical plate is mounted on a workbench, and the pair of conveyor belts are mounted vertically at intervals on the mounting vertical plate. The upper conveyor belt is vertically movable and adjustable. The adjusting component is mounted on the mounting vertical plate and is used to adjust the position of the upper conveyor belt. The loading platform is mounted on the mounting vertical plate, and when the pair of conveyor belts abut in the vertical direction, the discharge port of the loading platform is directly opposite the contact point of the pair of conveyor belts. The first driving device is mounted on the workbench and drives the pair of conveyor belts to rotate via a set of gears. As a preferred embodiment of this application, the cutting device of this application provides an initial placement position for the metal rods on a loading platform, ensuring that the metal rods can be stably supported in the initial stage. Its discharge port is directly opposite the contact point of a pair of conveyor belts, allowing the metal rods to be accurately transferred onto the conveyor belts, achieving accurate conveying and docking of the metal rods and avoiding deviation or jamming of the metal rods during the initial transmission. The upper conveyor belts are vertically adjustable, a design that can accommodate metal rods of different diameters. For thinner metal rods, the vertical distance between the two conveyor belts can be reduced, enhancing the clamping and conveying stability of the metal rods. For thicker rods, the distance is increased, ensuring that the metal rods can pass smoothly and be effectively transmitted, improving the versatility of the feeding mechanism for metal rods of different specifications. The gear set ensures efficient power transmission and ensures that the two conveyor belts rotate synchronously. Synchronous rotation ensures that the metal rods are subjected to uniform force during transmission, preventing twisting or tilting due to differences in conveyor belt speeds, and ensuring that the metal rods move stably and uniformly towards the grinding mechanism.

[0012] Furthermore, in a cutting device of this application, the mounting vertical plate includes: a first mounting vertical plate, which is mounted on a workbench; the adjusting component includes: a rotating plate, which is rotatably mounted on the first mounting vertical plate; a protrusion is provided on the side of the rotating plate near the first mounting vertical plate; the protrusion passes through the first mounting vertical plate; when a pair of conveyor belts abut in the vertical direction, the rotation axis of the rotating plate is horizontally collinear with the protrusion; a movable block is floating on the side of the first mounting vertical plate away from the rotating plate; a groove extending in the vertical direction is provided on the first mounting vertical plate; a connector is provided in the groove; the two ends of the connector are respectively connected to the movable block and the conveyor belt above; an extension corresponding to the protrusion is provided on the side of the movable block near the first mounting vertical plate; when the rotating plate rotates around the rotation axis of the first mounting vertical plate and the rotating plate, the protrusion slides on the extension in the X direction, and in the vertical direction, the protrusion drives the movable block to move upward. As a preferred embodiment of this application, a cutting device is provided. When the position of the upper conveyor belt needs to be adjusted, an external force causes a rotating plate to rotate around the rotation axis of the first mounting vertical plate and the rotating plate. A protrusion is provided on the side of the rotating plate near the first mounting vertical plate, and a moving block has an extension corresponding to the protrusion on the side near the first mounting vertical plate. The two work together; during rotation, the protrusion slides on the extension under the influence of the rotating plate, and the protrusion drives the extension to move upward in the vertical direction, thereby causing the moving block to move upward. Simultaneously, the moving block is connected to the upper conveyor belt via a connecting member. The connection mechanism allows the moving block to move vertically, synchronously driving the upper conveyor belt to move up and down via the connecting piece. This enables the upper conveyor belt's vertical position to be adjusted by rotating the rotating plate to accommodate metal rods of different diameters, ensuring the metal rods are stably clamped between the upper and lower conveyor belts for transport. When it is necessary to reduce the distance between the upper and lower conveyor belts, the rotating plate is rotated in the opposite direction, causing the protrusion to slide in the opposite direction on the extension, driving the moving block downwards, and thus causing the upper conveyor belt to move downwards, reducing the distance between it and the lower conveyor belt.

[0013] Furthermore, in a cutting device of this application, a pair of guide posts are provided on the side of the first mounting vertical plate away from the rotating plate. The pair of guide posts are mounted on the first mounting vertical plate via a pair of mounting blocks. The pair of guide posts are spaced apart in the X direction. The moving block is sleeved on the pair of guide posts. A first elastic element is provided between the pair of guide posts. The two ends of the first elastic element abut against the mounting block and the moving block, respectively. As a preferred embodiment of this application, in a cutting device of this application, the guide posts provide guidance for the movement of the moving block, ensuring that the moving block can only move in the vertical direction along the axial direction of the guide posts. This ensures the accuracy and stability of the moving block's movement during adjustment, making the position adjustment of the upper conveyor belt more precise and avoiding deviations that could affect the clamping and conveying of the metal rod. During the adjustment process, after the rotating plate stops rotating, the first elastic element can use its own elasticity to keep the upper transmission belt pressed against the lower conveyor belt.

[0014] Furthermore, in one cutting device of this application, the grinding mechanism includes: a pair of mounting brackets, the pair of mounting brackets being spaced apart on a worktable in the X direction, each of the pair of mounting brackets having a floating grinding component, the pair of grinding components being arranged opposite each other in the vertical direction, and the metal rod being located between the pair of grinding components. As a preferred embodiment of this application, the floating grinding components in the cutting device ensure that the grinding components are always in contact with the outer surface of the metal rod during the grinding process, guaranteeing that the grinding work can be carried out uniformly and effectively. Simultaneously, the grinding components can move flexibly within a certain range to adapt to metal rods of different specifications and sizes, improving the adaptability of the grinding mechanism to metal rods of different specifications and thus improving the versatility of the cutting device.

[0015] Furthermore, in a cutting device of this application, the grinding assembly includes: a mounting plate, a grinding belt, and a second driving device. A set of rotating columns is arranged in a circumferential array on the mounting plate, and the grinding belt is sleeved on the set of rotating columns. The second driving device is installed on the side of the mounting plate away from the grinding belt, and the driving end of the second driving device is connected to the rotating columns. The mounting frame includes: a top plate and a pair of uprights. The pair of uprights are spaced apart on the worktable in the Y direction. The top plate is installed on the pair of uprights. A movable block is provided between the pair of uprights. The movable block is connected to the mounting plate. A set of second elastic members is provided between the movable block and the top plate. The set of second elastic members is spaced apart in the Y direction, and the two ends of the second elastic members abut against the movable block and the top plate, respectively. As a preferred embodiment of this application, a cutting device comprises a second driving device that drives a rotating column to rotate a grinding belt to grind the surface of a metal rod. The rotating columns arranged circumferentially on the mounting plate ensure stable tension and operation of the grinding belt, achieving uniform grinding. The second elastic element enables the grinding assembly to float. When there is a deviation in the diameter of the metal rod or an uneven surface, the grinding assembly can adaptively adjust through the elastic deformation of the second elastic element, always maintaining appropriate grinding pressure with the surface of the metal rod. This ensures the grinding effect while avoiding damage to the metal rod or wear on the grinding belt due to excessive pressure, thus extending the service life of the equipment.

[0016] Furthermore, in this application, a cutting device is provided, wherein the cutting mechanism includes: a cutting blade, a blade holder, a linear drive device, and a pair of material carriers. The pair of material carriers are spaced apart on a worktable in the X direction. The blade holder is movably disposed between the pair of material carriers. The cutting blade is detachably mounted on the blade holder. The linear drive device is mounted on the worktable, and the drive end of the linear drive device is connected to the blade holder. Each of the pair of material carriers is provided with a corresponding material hole, through which the metal rod passes axially. As a preferred embodiment of this application, a cutting device is provided in which the cutting blade is detachably mounted on the blade holder. When the blade wears or is damaged due to frequent use, the operator can quickly remove it from the blade holder and replace it with a new blade, improving the economy of the cutting device. The blade holder is movably positioned between a pair of material carriers. After the metal bar passes through the material hole and is positioned, the linear drive device drives the blade holder to move and cut the metal bar. According to the preset length requirements, the polished metal bar is accurately cut into small segments. During the cutting process, the metal bar is located within the material hole, ensuring the accuracy of the cutting position and preventing the metal bar from shifting or shaking during the cutting process, thereby improving the cutting accuracy.

[0017] Furthermore, in one cutting device of this application, the collecting assembly includes: a collecting cover and a collecting box with an open top. The collecting cover is mounted on a material carrier on the side away from the cutting mechanism. The collecting cover includes an inlet and an outlet. The inlet is connected to a material hole, and the outlet is directly opposite the opening of the collecting box. As a preferred embodiment of this application, in one cutting device, after a metal bar is cut by the cutting mechanism, the cut segments of the metal bar fall from the material hole. At this time, the inlet of the collecting cover can accurately receive these fallen segments and guide them to the outlet through an internal channel. This design ensures that the cut segments of the bar can smoothly enter the collecting assembly, improving the efficiency and accuracy of collection.

[0018] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0019] This utility model provides a cutting device that integrates multiple functional modules such as a feeding mechanism, a grinding mechanism, a cutting mechanism, and a collecting component to achieve automated segmented cutting and grinding of metal bars. At the same time, the design of each mechanism is optimized to adapt to metal bars of different diameters, thereby improving production efficiency and equipment versatility.

Detailed Implementation

[0027] like Figure 1 As shown, a cutting device for segmenting and grinding a metal rod 1 includes: a worktable 2, corresponding to the feeding direction of the metal rod 1, the worktable 2 being provided with:

[0028] Feeding mechanism 3, which is used to convey metal rod 1;

[0029] Grinding mechanism 4 is used to grind the outer surface of the metal rod 1.

[0030] The material cutting mechanism 5 is used to cut the polished metal rod 1 to a preset length.

[0031] The material collection component 6 is used to collect the cut metal rods 1.

[0032] Based on the above structure, the principle of the cutting device is as follows: First, the operator places the metal rod 1 at a specific feeding position of the feeding mechanism 3 and starts the feeding mechanism 3. The metal rod 1 will move along the set track at a stable speed towards the grinding mechanism 4. Then, when the metal rod 1 enters the area of ​​the grinding mechanism 4, the drive device of the grinding mechanism 4 is activated to remove impurities from the surface of the metal rod 1. During the continuous conveying process, the outer surface of the metal rod 1 is fully ground by the grinding components of the grinding mechanism 4. Next, the ground metal rod 1 continues to be conveyed forward to the cutting mechanism 5, which can cut the ground metal rod 1 to a preset length. The cutting process enables segmented processing of the metal rod 1, meeting the specific requirements for different lengths of the metal rod 1. Finally, the collecting component 6 collects the cut metal rod 1, allowing for effective organization and storage of the processed metal rod 1, facilitating subsequent handling and use. This cutting device integrates multiple functional modules such as feeding, grinding, cutting, and collecting, enabling automated segmented cutting and grinding of the metal rod 1. This reduces the workload and labor intensity of manual operation, improves production cutting efficiency, and allows the metal rod 1 to undergo continuous and uninterrupted processing on the workbench 2 through feeding, grinding, cutting, and collecting, further enhancing production cutting efficiency.

[0033] In this embodiment, as Figure 2 , 3As shown, the feeding mechanism 3 includes: a loading platform 31, a mounting vertical plate 32, a first driving device 33, an adjusting component 34, and a pair of conveyor belts 35. The mounting vertical plate 32 is mounted on the workbench 2. The pair of conveyor belts 35 are mounted vertically at intervals on the mounting vertical plate 32. The upper conveyor belt 35 is vertically movable and adjustable. The adjusting component 34 is mounted on the mounting vertical plate 32 and is used to adjust the position of the upper conveyor belt 35. The loading platform 31 is mounted on the mounting vertical plate 32. When the pair of conveyor belts 35 abut in the vertical direction, the discharge port of the loading platform 31 is directly opposite the contact point of the pair of conveyor belts 35. The first driving device 33 is mounted on the workbench 2 and drives the pair of conveyor belts 35 to rotate through a set of gears 36. The loading platform 31 provides an initial placement position for the metal rod 1, ensuring that the metal rod 1 can be stably supported in the initial stage. Its discharge port is directly opposite the contact point of the pair of conveyor belts 35, allowing the metal rod 1 to accurately transition onto the conveyor belts 35, achieving accurate conveying and docking of the metal rod 1 and avoiding deviation or jamming during the initial transmission. The upper conveyor belts 35 are vertically adjustable, a design that can accommodate metal rods 1 of different diameters. For thinner metal rods 1, the vertical distance between the two conveyor belts 35 can be reduced. The spacing enhances the stability of clamping and conveying the metal rod 1; for thicker rods, the spacing is increased to ensure that the metal rod 1 can pass smoothly and be effectively transported, improving the versatility of the feeding mechanism 3 for metal rods 1 of different specifications; the gear set 36 ensures efficient power transmission and ensures that the two conveyor belts 35 rotate synchronously. Synchronous rotation ensures that the metal rod 1 is subjected to uniform force during transmission, and will not twist or tilt due to speed differences of the conveyor belts 35, ensuring that the metal rod 1 moves stably and uniformly towards the grinding mechanism 4. The first drive device 33 uses a motor.

[0034] In this embodiment, the mounting vertical plate 32 includes a first mounting vertical plate 321, which is mounted on the workbench 2. The adjusting assembly 34 includes a rotating plate 341, which is rotatably mounted on the first mounting vertical plate 321. A protrusion 342 is provided on the side of the rotating plate 341 near the first mounting vertical plate 321. The protrusion 342 passes through the first mounting vertical plate 321. When a pair of conveyor belts 35 abut in the vertical direction, the rotation axis of the rotating plate 341 is horizontally collinear with the protrusion 342. A movable adjustment mechanism is floating on the side of the first mounting vertical plate 321 away from the rotating plate 341. Block 343, the first mounting vertical plate 321 is provided with a groove 3210 extending in the vertical direction, the groove 3210 is provided with a connector 344, the two ends of the connector 344 are respectively connected to the moving block 343 and the conveyor belt 35 above. The moving block 343 is provided with an extension 345 corresponding to the protrusion 342 on the side near the first mounting vertical plate 321. When the rotating plate 341 rotates around the rotation axis of the first mounting vertical plate 321 and the rotating plate 341, in the X direction, the protrusion 342 slides on the extension 345, and in the vertical direction, the protrusion 342 drives the moving block 343 to move upward. When the position of the upper conveyor belt 35 needs to be adjusted, an external force causes the rotating plate 341 to rotate around the rotation axis of the first mounting vertical plate 321 and the rotating plate 341. The rotating plate 341 has a protrusion 342 on the side near the first mounting vertical plate 321, while the moving block 343 has an extension 345 corresponding to the protrusion 342 on the side near the first mounting vertical plate 321. The two work together; during rotation, the protrusion 342 slides on the extension 345 under the influence of the rotating plate 341, and the protrusion 342 drives the extension 345 upward in the vertical direction, thereby causing the moving block 343 to move upward. Simultaneously, the moving block 343 is connected to the upper conveyor belt 35 via the connecting member 344. When the moving block 343 moves vertically, it will synchronously drive the upper conveyor belt 35 to move up and down through the connecting piece 344. This allows the position of the upper conveyor belt 35 in the vertical direction to be adjusted by rotating the rotating plate 341 according to actual needs, so as to accommodate metal rods 1 of different diameters and ensure that the metal rods 1 can be stably clamped between the upper and lower conveyor belts 35 for conveying. When it is necessary to reduce the distance between the upper and lower conveyor belts 35, the rotating plate 341 is rotated in the opposite direction, and the protrusion 342 will slide in the opposite direction on the extension 345, driving the moving block 343 to move downward, thereby causing the upper conveyor belt 35 to move downward and reduce the distance between it and the lower conveyor belt 35.

[0035] In this embodiment, a pair of guide posts 346 are provided on the side of the first mounting vertical plate 321 away from the rotating plate 341. The pair of guide posts 346 are mounted on the first mounting vertical plate 321 via a pair of mounting blocks 347. The pair of guide posts 346 are spaced apart in the X direction. The moving block 343 is sleeved on the pair of guide posts 346. A first elastic member 348 is provided between the pair of guide posts 346. The two ends of the first elastic member 348 abut against the mounting blocks 347 and the moving block 343, respectively. The guide posts 346 provide guidance for the movement of the moving block 343, ensuring that the moving block 343 can only move in the vertical direction along the axial direction of the guide posts 346. This ensures the accuracy and stability of the movement of the moving block 343 during adjustment, making the position adjustment of the upper conveyor belt 35 more precise and avoiding deviations that could affect the clamping and conveying of the metal rod 1. During the adjustment process, after the rotating plate 341 stops rotating, the first elastic member 348 can use its elasticity to keep the upper conveyor belt 35 pressed against the lower conveyor belt 35. A pair of mounting blocks 347 are respectively mounted on the upper and lower ends of the guide post 346, and the first elastic element 348 is a spring.

Grinding components 42 are floatingly mounted on each of the mounting brackets 41, and the grinding components 42 are arranged opposite each other in the vertical direction. The metal rod 1 is located between the pair of grinding components 42. The floating grinding components 42 ensure that they remain in contact with the outer surface of the metal rod 1 during grinding, guaranteeing uniform and effective grinding. Simultaneously, the grinding components 42 can move flexibly within a certain range to accommodate metal rods 1 of different sizes, improving the adaptability of the grinding mechanism 4 to different specifications of metal rods 1 and thus enhancing the versatility of the cutting device.

[0037] In this embodiment, the polishing assembly 42 includes: a mounting plate 421, a polishing belt 422, and a second driving device 423. A set of rotating columns 424 are arranged circumferentially on the mounting plate 421. The polishing belt 422 is sleeved on the set of rotating columns 424.

A set of second elastic members 426 is provided between the movable block 425 and the top plate 411. The set of second elastic members 426 are spaced apart in the Y direction. The two ends of the second elastic members 426 respectively abut against the movable block 425 and the top plate 411. The second drive unit 423 drives the rotating columns 424 to rotate the grinding belt 422, grinding the surface of the metal rod 1. The rotating columns 424, arranged circumferentially on the mounting plate 421, ensure the stable tension and operation of the grinding belt 422, achieving uniform grinding. The second elastic element 426 makes the grinding assembly 42 float. When there is a deviation in the diameter of the metal rod 1 or the surface is uneven, the grinding assembly 42 can adaptively adjust through the elastic deformation of the second elastic element 426, always maintaining an appropriate grinding pressure with the surface of the metal rod 1. This ensures the grinding effect while avoiding damage to the metal rod 1 or wear on the grinding belt 422 due to excessive pressure, thus extending the service life of the equipment. There are three rotating columns 424 in one set, two second elastic elements 426 in one set, and a motor in the second drive unit 423.

[0038] In this embodiment, as Figure 6As shown, the material cutting mechanism 5 includes: a cutting blade 51, a tool holder 52, a linear drive device 53, and a pair of material carriers 54.

The drive end of the linear drive device 53 is connected to the tool holder 52. Each of the pair of material carriers 54 is provided with a corresponding material hole 50, through which the metal rod 1 passes axially. The cutting blade 51 is detachably mounted on the blade holder 52. When the blade wears or is damaged due to frequent use, the operator can quickly remove it from the blade holder 52 and replace it with a new blade, improving the economy of the cutting device. The blade holder 52 is movably positioned between a pair of material carriers 54. After the metal rod 1 passes through the material hole 50 and is positioned, the linear drive device 53 drives the blade holder 52 to move the cutting blade 51, cutting the metal rod 1 accurately into small segments according to the preset length requirements. During the cutting process, the metal rod 1 is located within the material hole 50, ensuring the accuracy of the cutting position and preventing the metal rod 1 from shifting or shaking during the cutting process, thereby improving the cutting accuracy.
