Description

Technical Field

[0001] This utility model relates to the field of CNC wire bending technology, and in particular to a wire feeding mechanism for a CNC wire bending robot. Background Technology

[0002] CNC wire bending robots are automated equipment widely used in construction steel bar processing, metal forming, and other industrial fields. They achieve wire bending through a precise CNC system, offering significant advantages in improving production efficiency, saving labor costs, and ensuring product quality. However, during the wire feeding process, the wire feeding mechanism, as a key component, directly affects the working efficiency and processing accuracy of the wire bending robot.

[0003] Traditional wire feeding mechanisms do not effectively limit the ends of the reinforcing bars during clamping, relying solely on the clamping force in the middle to fix the bars. This easily causes the reinforcing bars to shake or even slip during transport, resulting in reduced wire feeding accuracy, affecting the consistency of bending angles, and ultimately leading to product defects. Although some mechanisms have structures to limit the reinforcing bars, changing to reinforcing bars of different diameters requires complex replacement of limiting components of different diameters, making it impossible to adapt to different specifications of reinforcing bar diameters. This is time-consuming and labor-intensive, leading to decreased production efficiency and inconvenience in use. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a CNC wire bending robot wire feeding mechanism to solve the problem that traditional wire feeding mechanisms do not effectively limit the two ends of the steel bar during the clamping process, and only rely on the clamping force of the middle part to fix the steel bar, which affects the consistency of the bending angle, and cannot limit the steel bars of different specifications.

[0005] To achieve the above objectives, this utility model provides a wire feeding mechanism for a CNC wire bending robot, comprising a support platform, a fixed plate fixedly connected to the side wall of the support platform, two wire feeding drive wheels fixedly connected to the side wall of the fixed plate, a belt sleeved between the shafts of the two wire feeding drive wheels via pulleys, a first motor fixedly connected to the side wall of the support platform, the output end of the first motor fixedly connected to the shaft of one of the wire feeding drive wheels, an adjusting plate fixedly connected to the side wall of the fixed plate, two clamping wheels fixedly connected to the side wall of the adjusting plate, the wire feeding drive wheels and the clamping wheels being on the same vertical line, and a limiting mechanism for limiting the movement of the reinforcing bar fixedly connected to the side wall of the fixed plate.

[0006] Preferably, the limiting mechanism includes a support plate fixedly connected to the side walls of both sides of the support platform. Multiple evenly distributed fixed columns are fixedly connected to the side walls of each support plate. A fixed disk is fixedly connected to one end of each fixed column. Multiple evenly distributed slide rails are fixedly connected to the side walls of each fixed disk. Limiting rods are slidably connected inside each slide rail. A stabilizing wheel is rotatably connected to one end of each limiting rod. A sliding rod is fixedly connected to the side walls of each limiting rod. An adjusting gear is provided between the support plate and the fixed disk. Multiple evenly distributed arc-shaped through slots and rotating slots are formed on the side walls of the adjusting gear. One end of each fixed column penetrates the interior of the rotating slot. One end of each sliding rod extends into the interior of the arc-shaped through slot. A rotating rod is rotatably connected between the opposing surfaces of the two support plates. Gears are fixedly connected to both ends of the rotating rod. The adjusting gears mesh with each other. A second motor is fixedly connected to the side wall of the support platform. The output end of the second motor is fixedly connected to one end of the rotating rod.

[0007] Preferably, the side wall of the adjusting plate is provided with an inclined groove, the outer wall of the rotating rod is provided with a threaded groove, and a push post is threadedly fitted on the outer wall of the threaded groove. One end of the push post passes through the interior of the inclined groove and is slidably connected to the side wall of the fixed plate.

[0008] Preferably, the middle part of the support plate, the fixed plate, and the adjusting gear are all provided with a connecting groove.

[0009] Preferably, the outer walls of both the wire feeding drive wheel and the clamping wheel are provided with multiple anti-slip grooves that are evenly distributed at equal intervals.

[0010] Preferably, the diameter of the gear is smaller than the diameter of the adjusting gear.

[0011] Preferably, one end of the stabilizing wheel is in contact with the outer wall of the reinforcing bar.

[0012] The beneficial effects of this utility model are:

[0013] 1. The wire feeding mechanism of the CNC wire bending robot uses gears in the limiting mechanism to drive the adjusting gears to rotate. The adjusting gears drive the limiting rods to slide on the fixed plate and, through the stabilizing wheels, limit the two ends of the rebar in multiple directions. This ensures that the rebar remains stable during the feeding process, increasing the wire feeding accuracy. It solves the problem that most existing wire feeding mechanisms do not effectively limit the two ends of the rebar during clamping, relying only on the clamping force in the middle to fix the rebar. This easily causes the rebar to shake or even slip during feeding, leading to reduced wire feeding accuracy, affecting the consistency of the bending angle, and resulting in unqualified products. Therefore, it ensures that the angle and position of the rebar are accurate and stable when fed into the bending mechanism. At the same time, the limiting mechanism can clamp rebars of different specifications, improving the flexibility and production efficiency of the equipment and reducing complex operations in production.

[0014] 2. The wire feeding mechanism of the CNC wire bending robot, when the size of the steel bar is clamped by adjusting the limit rod in the limiting mechanism, will drive the rotating rod to rotate. Through this linkage structure, the clamping force of the clamping wheel on the middle of the steel bar can be precisely adjusted without the need for an additional power source. This design not only simplifies the complexity of the overall structure, but also makes maintenance more convenient. At the same time, since it does not rely on an additional power source, its wire feeding structure is more stable and easy to operate, and can maintain high efficiency and reliability during long-term operation.

[0024] like Figures 1 to 4 As shown, a CNC wire bending robot wire feeding mechanism includes a support platform 1, a fixed plate 2 fixedly connected to the side wall of the support platform 1, two wire feeding drive wheels 3 fixedly connected to the side wall of the fixed plate 2, a belt 4 sleeved between the shafts of the two wire feeding drive wheels 3 via pulleys, a first motor 5 fixedly connected to the side wall of the support platform 1, the output end of the first motor 5 fixedly connected to the shaft of one of the wire feeding drive wheels 3, an adjusting plate 6 fixedly connected to the side wall of the fixed plate 2, two clamping wheels 7 fixedly connected to the side wall of the adjusting plate 6, the wire feeding drive wheels 3 and the clamping wheels 7 being on the same vertical line, and a limiting mechanism for limiting the movement of the reinforcing bars fixedly connected to the side wall of the fixed plate 2.

[0025] Further, see attached document. Figures 2 to 4As shown, the limiting mechanism includes a support plate 8 fixedly connected to the side walls of the support platform 1. Multiple evenly distributed fixed posts 9 are fixedly connected to the side walls of the support plate 8. A fixed plate 10 is fixedly connected to one end of each fixed post 9. Multiple evenly distributed slide rails 11 are fixedly connected to the side walls of the fixed plate 10. Limiting rods 12 are slidably connected inside each slide rail 11. A stabilizing wheel 13 is rotatably connected to one end of each limiting rod 12. One end of each stabilizing wheel 13 contacts the outer wall of the reinforcing bar. Sliding rods 14 are fixedly connected to the side walls of each limiting rod 12. An adjusting gear 15 is provided between the support plate 8 and the fixed plate 10. Multiple evenly distributed arc-shaped through slots 16 and rotating slots 17 are provided on the side walls of the adjusting gear 15. One end of each fixed post 9 passes through... Inside the rotating groove 17, one end of the slide rod 14 extends into the interior of the arc-shaped through groove 16. A rotating rod 18 is rotatably connected between the opposing surfaces of the two support plates 8. Gears 19 are fixedly connected to both ends of the rotating rod 18. The adjusting gear 15 and the gear 19 mesh with each other. A second motor 20 is fixedly connected to the side wall of the support platform 1. The output end of the second motor 20 is fixedly connected to one end of the rotating rod 18. An inclined groove 21 is opened on the side wall of the adjusting plate 6. A threaded groove 22 is opened on the outer wall of the rotating rod 18. A push column 23 is threadedly fitted on the outer wall of the threaded groove 22. One end of the push column 23 passes through the interior of the inclined groove 21 and is slidably connected to the side wall of the fixed plate 2. A connecting groove 24 is opened in the middle part of the support plate 8, the fixed plate 10, and the adjusting gear 15.

[0026] When using the limiting mechanism, first, the reinforcing bar is inserted into the connecting groove 24 and placed on top of the wire feeding drive wheel 3. Then, the power is turned on, and the second motor 20 is started. The second motor 20 drives the rotating rod 18 to rotate. When the rotating rod 18 rotates, it drives the gears 19 at both ends to rotate. When the gears 19 rotate, they drive the adjusting gear 15 to rotate counterclockwise. The adjusting gear 15 drives the arc-shaped through groove 16 to rotate. The arc-shaped through groove 16 pushes the sliding rod 14 to slide inside the arc-shaped through groove 16. When the sliding rod 14 slides, it drives the limiting rod 12 to slide on the slide rail 11 and contact the reinforcing bar through the stabilizing wheel 13, thereby limiting the limiting rod 12. The reinforcing bar can only slide laterally. Simultaneously, when the rotating rod 18 rotates, it drives the pushing column 23 to move to the right via the threaded groove 22. The pushing column 23 then slides within the inclined groove 21 and pushes the adjusting plate 6 downwards via the inclination of the groove 21. As the adjusting plate 6 slides, it drives the two clamping wheels 7 downwards and into contact with the outer surface of the reinforcing bar. Then, the first motor 5 is activated, driving one of the wire feeding drive wheels 3 to rotate. When the wire feeding drive wheel 3 rotates, it synchronously drives the other wire feeding drive wheel 3 to rotate via the belt 4, thereby driving the reinforcing bar to slide to the right, allowing one end of the reinforcing bar to enter the bending mechanism for bending. This is achieved by limiting... In the positioning mechanism, gear 19 drives adjusting gear 15 to rotate. Adjusting gear 15 drives limiting rod 12 to slide on fixed plate 10 and limits both ends of the reinforcing bar in multiple directions through stabilizing wheel 13. This ensures that the reinforcing bar remains stable during the conveying process, increasing wire feeding accuracy. This solves the problem that most existing wire feeding mechanisms do not effectively limit both ends of the reinforcing bar during clamping, relying only on the clamping force in the middle to fix the reinforcing bar. This can easily cause the reinforcing bar to shake or even slip during conveying, resulting in reduced wire feeding accuracy, affecting the consistency of bending angle, and thus leading to product defects. Therefore, this mechanism ensures that the angle and position of the reinforcing bar are within acceptable limits when it is fed into the bending mechanism. With precise and stable operation, the limiting mechanism can clamp steel bars of different specifications, improving the flexibility and production efficiency of the equipment and reducing complex operations in production. When the limiting rod 12 is adjusted to clamp the size of the steel bar, the limiting mechanism will drive the rotating rod 18 to rotate. Through this linkage structure, the clamping force of the clamping wheel 7 on the middle of the steel bar can be precisely adjusted without the need for an additional power source. This design not only simplifies the complexity of the overall structure, but also makes maintenance more convenient. At the same time, since it does not rely on an additional power source, its wire feeding structure is more stable and easier to operate, and can maintain high efficiency and reliability during long-term operation.

[0027] Further, see attached document. Figure 2 As shown, the outer walls of the wire feeding drive wheel 3 and the clamping wheel 7 are provided with multiple anti-slip grooves that are evenly distributed at equal intervals. The anti-slip grooves on the outer walls of the wire feeding drive wheel 3 and the clamping wheel 7 increase the friction between the outer walls of the wire feeding drive wheel 3 and the clamping wheel 7 and the outer wall of the reinforcing bar, thus facilitating the conveying of the reinforcing bar.

[0028] Further, see attached document. Figure 4 As shown, the diameter of gear 19 is smaller than the diameter of adjusting gear 15. By making gear 19 smaller than the diameter of adjusting gear 15, the rotation speed of adjusting gear 15 is reduced, thereby achieving deceleration. This facilitates the clamping of the limit rod 12 with the steel bar, avoids clamping too fast, and increases clamping accuracy.
