Description

Technical Field

[0001] This utility model relates to the technical field of busbar bending, and in particular to a CNC busbar bending machine with adjustable feeding function. Background Technology

[0002] A busbar is a shared pathway through which multiple devices are connected in parallel branches. As the applications of busbars increase, higher demands are being placed on their shape to improve space utilization. Currently, busbar production typically involves using a busbar bending machine to bend the busbar multiple times to obtain the desired shape.

[0003] Existing CNC busbar bending machines generally consist of components such as a feeding rack, motor, conveyor rollers, and conveyor belt. The speed of the conveyor belt can be adjusted according to the processing rhythm of the bending machine to ensure that the busbar material can be accurately and timely supplied to the bending position. The busbar to be processed is placed on the worktable of the bending machine and fixed by a clamp or positioning device to ensure that the busbar does not shift during the bending process. According to the requirements of the busbar material, thickness, bending angle, and shape, a suitable bending die is selected and installed on the upper and lower die holders of the bending machine. Finally, through the squeezing action of the upper and lower dies, the busbar is bent and deformed according to the set angle and shape until the required bending angle is achieved.

[0004] Existing bending machines require manual removal of the processed busbar from the machine after each bending operation before the next loading and bending process can begin. This process is time-consuming and hinders overall production efficiency, especially during mass production. Therefore, a CNC busbar bending machine with adjustable feeding function is proposed to address these issues. Summary of the Invention

[0009] As a further description of the above technical solution: a material feeding bin is fixedly connected to the side of the top frame. The material feeding bin is rectangular in shape and has openings at the top and bottom.

[0010] As a further description of the above technical solution: the feeding box and the collection box are configured to cooperate, and an outlet is provided on one side of the top frame, the outlet being adapted to the size of the feeding box.

[0011] As a further description of the above technical solution: a stop block is fixedly connected to the inner side of the baffle plate, and the baffle plate is in the shape of an "L".

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting up a squeezing inclined block in conjunction with the movement of the feeding box, the longitudinal elastic potential energy of the No. 1 spring drives the two baffles and blocks to rebound. Through the cooperation of the baffles and blocks, the busbar is intermittently fed, reducing the need for personnel to frequently bend over, lift their hands, and perform other actions to move the busbar, thereby reducing labor intensity and improving the stability of product quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a CNC busbar bending machine with adjustable feeding function, including a base frame 1, a top frame 7 fixedly connected to the top of the base frame 1, and a feeding bin 9 fixedly connected to the side of the top frame 7, making the feeding bin 9 more stable on one side of the top frame 7. The feeding bin 9 is rectangular in shape and has openings at both the top and bottom. A limit block 11 is fixedly connected to one side of the top frame 7, and the bottom of the limit block 11 is movably connected through... A rack 12 is connected to the top frame 7, and a limiting block 11 limits the rack 12, making the rack 12 slide more stably inside the limiting block 11. A rotating rod 16 is rotatably connected to one side of the top frame 7 via a bearing, so that one end of the rotating rod 16 rotates on one side of the top frame 7. A driven gear 17 is fixedly sleeved on the surface of the rotating rod 16. The rotating rod 16 drives the driven gear 17 to rotate. The rack 12 meshes with the adjacent side of the driven gear 17, so that when the rack 12 moves up and down, it can drive the driven gear 17. 7. The rotating rod 16 rotates in both directions. One end of the rotating rod 16 is fixedly connected to a baffle plate 14, allowing the baffle plate 14 to rotate in both directions with the rotating rod 16. The bottom of the rack 12 is fixedly connected to a wedge block 10. The feeding box 3 presses the inclined surface of the wedge block 10, causing the wedge block 10 to move upward. A first spring 13 is sleeved on the surface of the rack 12. The two ends of the first spring 13 are fixedly connected to the limiting block 11 and the adjacent side of the wedge block 10, respectively. The longitudinal elastic potential energy of the first spring 13 drives the two baffle plates 14. The stop block 15 rebounds, and the inner side of the baffle plate 14 is fixedly connected to the stop block 15. The stop block 15 is used to intercept the excess busbars of the upper layer. The baffle plate 14 is "L" shaped, so that the two baffle plates 14 can rotate inward or outward. When the busbars at the end of the baffle plate 14 are perpendicular to the two baffle plates 14, the gap between the baffle plate 14 and the stop block 15 is used for material feeding. The top of the stop block 15 is used to intercept the upper busbars. The inner side of the top frame 7 is fixedly installed with a conveyor belt 2, which is used to transport the feeding box 3.

[0026] Reference Figure 5A movable rod 21 is movably connected to the inclined surface of the baffle plate 14, allowing the movable rod 21 to slide on the inner wall of the baffle plate 14. One end of the movable rod 21 is fixedly connected to a partition plate 20. During the unloading process, the partition plate 20 is used to intercept the upper busbar. A limiting ring 22 is fixedly sleeved on the surface of the movable rod 21, and a second spring 23 is sleeved on the surface of the movable rod 21. One end of the second spring 23 is fixedly connected to the end face of the limiting ring 22. The elastic potential energy of the second spring 23 allows the movable rod 21 to rebound. A sliding groove is formed on the inner wall of the baffle plate 14, and the limiting ring 22... The edge of the slide is in contact with and slidably connected to the wall of the chute. The chute provides a limiting function for the limiting ring 22, making the limiting ring 22 slide more stably in the chute. The other end of the second spring 23 is fixedly connected to the chute. When the two baffles 14 are perpendicular, the two moving rods 21 are squeezed by the limiting block 11, which drives the limiting ring 22 on the moving rod 21 to slide in the chute. The limiting ring 22 squeezes the second spring 23, thereby driving the partition 20 to move. The partition 20 intercepts the upper busbar. The conveyor belt 2 is equipped with a positioning component.

[0027] Reference Figure 1 , Figure 2 The positioning component includes a feeding box 3, which is fixedly connected to the top of the conveyor belt 2. Electric telescopic rods 4 are fixedly installed on all four sides of the feeding box 3. Positioning plates 5 are fixedly connected to the telescopic ends of the electric telescopic rods 4. The electric telescopic rods 4, in conjunction with the positioning plates 5, achieve the positioning effect of the busbar in the feeding box 3. The feeding box 3 is configured to cooperate with the inclined block 10. The side of the feeding box 3 can press against the inclined surface of the inclined block 10. A collection box 19 is fixedly connected to one side of the base frame 1. The top opening of the collection box 19 is used to collect the bent busbar. With the feeding box 3 and collection box 19 working together, as the conveyor belt 2 continues to operate, the internal busbar is tilted by the feeding box 3, causing it to fall into the collection box. The material is collected in the collection box 19, and finally the feeding box 3 returns to the top of the conveyor belt 2 under the operation of the conveyor belt 2. An outlet is opened on one side of the top frame 7. The outlet is adapted to the size of the feeding box 3 so that the feeding box 3 can pass through the outlet. With the help of the first spring 13, the baffle plate 14 is rotated in the opposite direction. An electric cylinder 8 is fixedly installed on the top of the top frame 7. The extension end of the electric cylinder 8 is fixedly connected to the pressure block 18. The bottom of the pressure block 18 is opened with a groove. The bottom of the feeding box 3 is fixedly connected to the pressure sill 6. The pressure block 18 is set to cooperate with the pressure sill 6 through the groove. The extension end of the electric cylinder 8 drives the pressure block 18 to move downward. The groove at the bottom of the pressure block 18 is used to squeeze the pressure sill 6 downward, thereby pressing and bending the busbar.

[0028] Working principle: Turning on the control switch of conveyor belt 2 starts it into operation. The control switch controls the speed of conveyor belt 2. Conveyor belt 2 transports the material box 3, which in turn presses against the inclined surface of the inclined block 10, causing it to move upwards. The rack 12 follows the upward movement of the inclined block 10. Through the meshing of the rack 12 with the driven gear 17, the rack 12 drives the driven gear 17 to rotate. The driven gear 17 then drives the rotating rod 16 to rotate, which in turn drives the baffle plate 14 to move in the opposite direction. As the stop block 15 and the baffle plate 14 are fixedly connected, material is fed through the top opening of the feeding hopper 9. The top of the stop block 15 is piled up to the inside of the feeding hopper 9. When the two baffle plates 14 rotate in opposite directions, the bottom of the baffle plate 14 is perpendicular to the two baffle plates 14. The two moving rods 21 are squeezed by the limiting block 11, which drives the limiting ring 22 on the moving rod 21 to slide in the groove. The limiting ring 22 squeezes the second spring 23, thereby driving the partition plate 20 to move. The partition plate 20 feeds the upper baffle plate. The feed cable at the end of the baffle plate 14 falls into the feeding box 3. Then, the collecting box 19 squeezes the inclined block 10 and passes through the outlet. The longitudinal elastic potential energy of the first spring 13 causes the two baffle plates 14 and the stop block 15 to rebound. Excess feed cable on the upper layer is intercepted by the stop block 15. By activating the electric telescopic rod 4, the telescopic end of the electric telescopic rod 4 achieves a positioning effect on the feed cable in the feeding box 3. When the feeding box 3 enters below the pressure block 18, the operation of the conveyor belt 2 stops, and then the electric cylinder 8 is activated. The telescopic end of cylinder 8 drives the pressure block 18 to move downwards. The bottom groove of the pressure block 18 presses down on the pressure sill 6, thereby pressing and bending the busbar. After the busbar is bent on the inner wall of the feeding box 3, the electric telescopic rod 4 is activated in the opposite direction, so that the telescopic end of the electric telescopic rod 4 loosens the busbar around. Then, as the conveyor belt 2 continues to operate, the busbar inside the feeding box 3 tilts, causing it to fall into the collection box 19 for collection. Finally, the feeding box 3 returns to the top of the conveyor belt 2 under the operation of the conveyor belt 2.
