Description

Technical Field

[0001] This utility model relates to the field of copper wire cutting technology, specifically a copper wire cutting device. Background Technology

[0002] In industrial fields such as electronic component manufacturing and wire and cable processing, copper wire cutting is a key process to ensure the accuracy of subsequent production. Existing copper wire cutting devices are mostly composed of a feeding mechanism, cutting tools and a frame. The copper wire is transported by a feeding wheel driven by a motor, and the cutting action is completed by a cylinder or hydraulic mechanism. This can meet the basic batch cutting needs and is widely used in the production lines of small and medium-sized processing enterprises.

[0003] Most current copper wire cutting devices have shortcomings in controlling the cutting length. They lack precise length limiting mechanisms and rely on operators to visually observe the extension length of the copper wire or manually measure and mark it before starting the cutting program. This not only makes it difficult to ensure the consistency of the length of each copper wire segment, but also requires a large amount of labor costs to monitor the cutting process. At the same time, the automation level of the device is low, and it cannot achieve continuous automated operation of feeding, length detection and cutting. It is easy for the product qualification rate to decrease due to human judgment errors. Utility Model Content

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figs. 1 to 4 This utility model provides a technical solution: a copper wire cutting device, including a fixed plate 1, a first support plate 2 fixedly connected to the upper side of the fixed plate 1, an auxiliary wire feeding mechanism 3 provided on one side of the first support plate 2, a second support plate 4 fixedly connected to the upper side of the fixed plate 1, a driving mechanism 5 provided on one side of the second support plate 4, a copper wire guide plate 6 fixedly connected to the upper side of the fixed plate 1, a cutting blade 7 provided on one side of the copper wire guide plate 6, and an L-shaped frame 8 fixedly connected to the upper side of the fixed plate 1. A slider 9 is slidably fitted on one side of the L-shaped frame 8, and a lever 10 is rotatably fitted on one side of the slider 9. An L-shaped push plate 11 is mounted on the upper end of the lever 10. An mounting rod 12 is fixedly connected to the upper side of the fixing plate 1. A sleeve 13 is fitted on the upper end of the mounting rod 12. An L-shaped pad 14 that cooperates with the drive mechanism 5 is fixedly connected to the outer side of the sleeve 13. One end of the L-shaped push plate 11 cooperates with one side of the L-shaped pad 14. A spring 15 is fitted on the mounting rod 12 and abuts against the lower end of the sleeve 13. A tension spring 16 is fixedly connected to one side of the L-shaped frame 8, and one end of the tension spring 16 is fixedly connected to the lower side of the L-shaped pad 14. A U-shaped limiting frame 17 is fixedly connected to one side of the L-shaped frame 8, and the L-shaped push plate 11 is slidably fitted on the inner wall of the U-shaped limiting frame 17. An auxiliary support plate 18 located on one side of the copper wire guide plate 6 is fixedly connected to the upper side of the fixed plate 1. Two cylindrical grooves 19 are opened on the upper side of the copper wire guide plate 6. Guide rods 20 are slidably and elastically fitted on the inner wall of the cylindrical grooves 19. The upper ends of the two guide rods 20 are fixedly connected to one side of the cutting blade 7. The copper wire is fed to the copper wire guide plate 6 via the auxiliary wire feeding mechanism 3. As the copper wire is continuously fed, one end of it gradually presses against the lower end of the lever 10. The lever 10 rotates around the slider 9, causing the upper L-shaped push plate 11 to slide along the U-shaped limit frame 17. At the same time, it pushes the L-shaped pad 14 to move to the position above the cutting blade 7. At this time, the sleeve 13 moves slightly along the mounting rod 12 and the spring 15 is in a pre-compression state. When the drive mechanism 5 operates, its pressure plate 56 moves down and cooperates with the already positioned L-shaped pad 14 to jointly apply downward pressure to the cutting blade 7. The cutting blade 7 moves down under the pressure, and the guide rod 20 slides along the cylindrical groove 19 and provides elastic support to ensure stable cutting of the copper wire. After cutting is completed, the drive mechanism 5 resets, and the tension spring 16 pulls the L-shaped pad 14 back up, causing the lever 10 and the L-shaped push plate 11 to reset, preparing for the next copper wire feeding and cutting, effectively improving cutting accuracy and action coordination.

[0019] In this embodiment, the auxiliary wire feeding mechanism 3 includes a fixed wire feeding wheel 31 rotatably engaged with one side of the first support plate 2. An adjustment groove 32 is provided on one side of the first support plate 2, and an adjustment block 33 is slidably engaged with the inner wall of the adjustment groove 32. An adjustment screw 34 is threadedly engaged with the upper end of the first support plate 2, and a movable wheel 35, which engages with the fixed wire feeding wheel 31, is rotatably engaged with one side of the adjustment block 33. The lower end of the adjustment screw 34 is located inside the adjustment groove 32, and the lower end of the adjustment screw 34 rotatably engages with the upper side of the adjustment block 33. Rotating the adjustment screw 34 causes its lower end to drive the adjustment block 33 to slide up and down along the adjustment groove 32 of the first support plate 2, adjusting the distance between the movable wheel 35 and the fixed wire feeding wheel 31. When the copper wire passes between the fixed wire feeding wheel 31 and the movable wheel 35, the two work together to guide and limit the copper wire, allowing for flexible adjustment of the spacing according to the copper wire diameter. This prevents the copper wire from shifting or loosening during feeding, ensuring smooth copper wire transport and laying the foundation for subsequent precise cutting, thus adapting to the processing needs of copper wires of different specifications.

[0020] In this embodiment, the drive mechanism 5 includes a drive motor 51 mounted on one side of the second support plate 4. The output end of the drive motor 51 extends to one side of the second support plate 4 and is fixedly connected to a drive disk 52. A connecting rod 53 is rotatably engaged at the outer edge of the drive disk 52. A dovetail guide rail 54 is vertically mounted on one side of the second support plate 4. A slide block 55 is slidably engaged on the dovetail guide rail 54. A pressure plate 56 that mates with the L-shaped pad 14 is fixedly connected to one side of the slide block 55. The upper end of the connecting rod 53 is rotatably engaged with one side of the slide block 55, and the pressure plate 56 is located above the cutting blade 7. Start the drive motor 51, whose output drives the drive disk 52 to rotate. The drive disk 52 pulls the slide block 55 up and down along the dovetail guide rail 54 through the connecting rod 53 on the edge. The slide block 55 drives the pressure plate 56 to move down. The pressure plate 56 presses the L-shaped pad 14 to trigger the cutting action. The drive disk 52 continues to rotate, and the connecting rod 53 pushes the slide block 55 and the pressure plate 56 to rise, completing one drive cycle. This mechanism realizes automated transmission through motor drive, replaces manual operation, improves the stability and automation of the cutting action, and reduces human error.

[0021] When using the device, first adjust the distance between the movable wheel 35 and the fixed feeding wheel 31 by adjusting the screw 34 of the auxiliary feeding mechanism 3 according to the diameter of the copper wire. Pass the copper wire through the two and send it to the copper wire guide plate 6. The copper wire is continuously fed on the guide plate. One end of the wire presses the lower end of the lever 10, causing the lever 10 to rotate around the slider 9, which in turn pushes the L-shaped pad 14 to move above the cutting blade 7. The sleeve 13 moves slightly along the mounting rod 12 and pre-compresses the spring 15. The drive motor 51 of the drive mechanism 5 is started. The drive disk 52 drives the slide 55 and the pressure plate 56 to move down along the dovetail guide rail 54 through the connecting rod 53. The pressure plate 56 and the L-shaped pad 14 cooperate to apply pressure, pushing the cutting blade 7 down along the guide rod 20 and the cylindrical groove 19 to complete the cutting of the copper wire of the specified length. After cutting, the drive motor 51 drives the drive disk 52 to reset. The tension spring 16 pulls the L-shaped pad 14 to rise. The lever 10 and the L-shaped push plate 11 reset synchronously. The copper wire continues to be fed into the next cycle, realizing automated and precise continuous cutting.
