Description

Technical Field

[0001] This invention relates to copper busbar bending equipment, specifically to a copper busbar production equipment and method. Background Technology

[0002] Copper busbars, also known as copper busbars or copper busbars, are long conductors made of copper with a rectangular or chamfered (rounded) rectangular cross-section. Copper busbars are used in circuits to transmit current and connect electrical equipment. They are widely used in electrical equipment, especially in complete sets of power distribution equipment, particularly in electrical cabinets in substations. However, due to the special application of copper busbars, the manufactured copper busbars need to be bent to adapt to installation requirements.

[0003] Traditional copper busbar production equipment requires manual handling of the copper busbars during bending; the busbars cannot advance independently for bending. The pressing head at the front of the hydraulic device in traditional bending machines is usually fixed and cannot be adjusted as needed, failing to meet the production requirements of different copper busbars. Furthermore, traditional bending devices require multiple forming processes, resulting in burrs and other defects. Therefore, we propose a copper busbar production equipment and method. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide copper busbar production equipment to solve the technical problem that the current extrusion head needs to be adjusted according to different copper busbars, requiring multiple forming processes that produce burrs.

[0005] To achieve the objectives of this invention, the technical solution adopted is as follows: A copper busbar production equipment is designed, comprising a base, an upper telescopic tube, and a hydraulic rod installed inside the upper telescopic tube. A bending die is provided at one end of the base. Several evenly spaced guide rollers are rotatably arranged in a groove at the upper end of the base. An upper support frame is fixedly provided on the outer wall of the base. At least two lower telescopic tubes are fixedly provided at the lower end of the upper support frame. A conveyor belt frame is fixedly provided at the telescopic end of the lower telescopic tubes. A conveyor belt corresponding to the guide rollers is provided at the lower end of the conveyor belt frame. An L-shaped plate is laterally movable at one end of the upper support frame. The L-shaped plate is fixed to the fixed end of the upper telescopic tube. A bracket is fixedly provided at the telescopic end of the upper telescopic tube. A detachable and rotatable extrusion head adapted to the bending die is provided at the lower end of the bracket, and multiple dies for extrusion are provided on the surface of the extrusion head.

[0006] Preferably, a drive roller is rotatably arranged on the side of the upper support frame near the bracket, and multiple driven rollers are rotatably arranged on the other side of the lower end of the upper support frame. The drive roller abuts against the surface of the driven roller and the inner surface of the conveyor belt and can roll. There is a space between the conveyor belt and the guide roller to accommodate the copper busbar.

[0007] Preferably, a lower servo motor is fixedly mounted on one end of the conveyor belt frame and on the side corresponding to the axis of the drive roller by screws. The output shaft of the lower servo motor movably passes through the side wall of the conveyor belt frame and is fixed to the central axis of the drive roller.

[0008] Preferably, the support has a first through hole on one side and a threaded hole on the other side, and the end of the extrusion head has at least four second through holes of the same size as the first through hole.

[0009] Preferably, a half-threaded screw is inserted inside the second through hole and the first through hole, and the threaded end of the half-threaded screw is threaded with the threaded hole.

[0010] Preferably, springs are fixedly installed at both ends of the inner cavity of the lower telescopic tube, and the springs are made of high-strength material.

[0011] Preferably, the lower end of the L-shaped plate is provided with a groove for the lateral sliding of the upper telescopic tube. Both ends of the groove are rotatably provided with screws threaded to the fixed end of the upper telescopic tube. An upper servo motor is fixedly provided at one end of the L-shaped plate, and the output shaft of the upper servo motor passes through the L-shaped plate, is located in the groove, and is fixed to one end of the screw through a coupling.

[0012] Preferably, a pressure sensor is fixedly installed between the telescopic end of the upper telescopic tube and the bracket.

[0013] A method for using copper busbar production equipment:

[0014] S1. During automatic conveying, the worker first inserts the copper busbar between the conveyor belt and the guide roller. This process will compress the spring. Under the reaction of the spring, the conveyor belt presses the copper busbar tightly onto the guide roller. The lower servo motor receives a signal from the compiler and its output shaft rotates, which drives the drive roller to rotate. The drive roller drives the conveyor belt to rotate, thereby moving the copper busbar forward on the upper end of the guide roller. During this process, the guide roller rotates around its own axis. The lower servo motor can act when it receives a signal. It can be used in conjunction with a bending device and its pressure sensor. After bending is completed, the lower servo motor receives a signal and continues to work.

[0015] S2. When adjusting the extrusion head mold according to the copper busbar, the worker selects the extrusion head mold according to the copper busbar specifications. The worker removes the half-threaded screw with tools, allowing the extrusion head to rotate in the bracket. The user rotates the required extrusion head mold downwards to align it with the bending die, and aligns the second through hole of the extrusion head with the first through hole. Then, the half-threaded screw is inserted into the second and first through holes, so that the threaded end of the half-threaded screw is screwed into the threaded hole provided in the bracket, thereby achieving fixation. The head size of the half-threaded screw should be larger than the diameter of the first through hole, so that the extrusion head can be fixed on the bracket. At the same time, the contact position between the half-threaded screw and the second and first through holes is a smooth surface, and the outer diameter of the half-threaded screw is the same as the inner diameter of the second and first through holes, so that they can be inserted and fixed.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The lower servo motor drives the drive roller, which in turn rotates the conveyor belt. The conveyor belt moves the copper busbar forward on the upper end of the guide roller. The pressure sensor determines the degree of bending based on the pressure received. When the pressure is reached, a signal is sent to cause the hydraulic rod and the lower servo motor to perform their respective actions, so that the conveying device can run automatically and realize the feeding and material speed of the copper busbar, thus facilitating the bending of the copper busbar.

[0018] 2. The extrusion head can rotate in the bracket. The user rotates the extrusion head mold to be used directly downwards so that it corresponds with the bending die. Different extrusion dies can be selected according to different copper busbars and can be adjusted as needed to meet the production of different copper busbars. This bending device can form in one step. When the extrusion die and the bending die are matched, the stamping will not cause burrs. Attached Figure Description

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

[0025] like Figures 1 to 4 As shown, a copper busbar production equipment includes a base 1, an upper telescopic tube 5, and a hydraulic rod 20 installed inside the upper telescopic tube 5. A bending die 8 is provided at one end of the base 1. Several guide rollers 15 are rotatably arranged at even intervals in the groove at the upper end of the base 1. An upper support frame 2 is fixedly provided on the outer wall of the base 1. At least two lower telescopic tubes 11 are fixedly provided at the lower end of the upper support frame 2. A conveyor belt frame 6 is fixedly provided at the telescopic end of the lower telescopic tubes 11. A conveyor belt 17 corresponding to the guide rollers 15 is provided at the lower end of the conveyor belt frame 6. An L-shaped plate 3 is laterally movable at one end of the upper support frame 2. The L-shaped plate 3 is fixed to the fixed end of the upper telescopic tube 5. A bracket 10 is fixedly provided at the telescopic end of the upper telescopic tube 5. An extrusion head 7 that is adapted to the bending die 8 and can be detached and rotated is provided at the lower end of the bracket 10. The surface of the extrusion head 7 is provided with multiple molds for extrusion.

[0026] Among them, the upper servo motor 4 and the lower servo motor 14 are matched with a compiler, microcomputer and other devices. The pressure sensor 24 and the hydraulic rod 20 are connected to the microcomputer, so that the four can be linked together and the equipment can realize automatic feeding. The pressure sensor 24 is designed. The extrusion mold on the surface of the extrusion head 7 and its fixing device can be integrally cast or integrally precision machined. The conveyor belt 17 can be made of a soft material with high friction, such as PU material.

[0027] This invention mainly provides two operating methods: automatic conveying and an extrusion head 7 that can be adjusted according to different copper busbar sizes, as detailed below:

[0028] During automatic conveying, the worker first inserts the copper busbar between the conveyor belt 17 and the guide roller 15. This process compresses the spring 12. Under the reaction of the spring 12, the conveyor belt 17 presses the copper busbar tightly onto the guide roller 15. The lower servo motor 14 receives a signal from the compiler and its output shaft rotates, driving the drive roller 13 to rotate. The drive roller 13 drives the conveyor belt 17 to rotate, thereby moving the copper busbar forward on the upper end of the guide roller 15. During this process, the guide roller 15 rotates around its own axis. The lower servo motor 14 can act upon receiving the signal. It can work in conjunction with the bending device and its pressure sensor 24. After bending is completed, the lower servo motor 14 receives a signal and continues to work. This setting allows the conveying device to run automatically, realizing the feeding and feeding speed of the copper busbar, thus facilitating the bending of the copper busbar.

[0029] When adjusting the die for the extrusion head 7 according to the copper busbar specifications, the worker selects the die for the extrusion head 7 based on the copper busbar specifications. The worker removes the half-threaded screw 9 using tools, allowing the extrusion head 7 to rotate within the bracket 10. The user rotates the die for the extrusion head 7 directly downwards, aligning it with the bending die 8, and aligning the second through hole 23 of the extrusion head 7 with the first through hole 22. Then, the half-threaded screw 9 is inserted into the second through hole 23 and the first through hole 22, so that the threaded end of the half-threaded screw 9 is screwed into the threaded hole 21 provided in the bracket 10, thereby achieving fixation. The head size of the half-threaded screw 9 must be larger than the diameter of the first through hole 22, so that the extrusion head 7 can be fixed on the bracket 10. At the same time, the contact area between the half-threaded screw 9 and the second through hole 23 and the first through hole 22 is a smooth surface. In addition, the outer diameter of the half-threaded screw 9 is the same as the inner diameter of the second through hole 23 and the first through hole 22, so that they can be inserted and fixed. In summary, this device can be adjusted as needed to meet the production of different copper busbars. This bending device can form in one step, and the stamping will not cause burrs.

[0030] Specifically, a drive roller 13 is rotatably mounted on the side of the upper support frame 2 near the bracket 10, and multiple driven rollers 16 are rotatably mounted on the other side of the lower end of the upper support frame 2. The surfaces of the drive roller 13 and driven rollers 16 abut against and can roll on the inner surface of the conveyor belt 17. A space for accommodating copper busbars is left between the conveyor belt 17 and the guide roller 15. In this invention, the drive roller 13 can drive the conveyor belt 17 to rotate under the action of friction, thereby realizing the conveying of copper busbars. Multiple driven rollers 16 can be set. The more rollers, the better the contact between the conveyor belt 17 and the surface of the copper busbar, making the copper busbar conveying more stable. If the number of driven rollers 16 is set too small, the contact between the conveyor belt 17 and the surface of the copper busbar will not be complete, which will reduce the friction between the conveyor belt 17 and the copper busbar, and may cause the copper busbar to slip.

[0031] Furthermore, a lower servo motor 14 is fixedly mounted on one end of the conveyor belt frame 6, corresponding to the axis of the drive roller 13, by screws. The output shaft of the lower servo motor 14 movably passes through the side wall of the conveyor belt frame 6 and is fixed to the central axis of the drive roller 13. In this invention, the lower servo motor 14 receives a compiler signal to rotate its output shaft, which in turn drives the drive roller 13 to rotate. Due to the high rotational precision of the servo motor, the conveyor belt 17 moves the copper busbar a specified distance, thereby increasing the bending effect and accuracy of the bending device. The conveyor belt frame 6 can also support the output shaft of the lower servo motor 14.

[0032] Furthermore, the bracket 10 has a first through hole 22 on one side and a threaded hole 21 on the other side. The end of the extrusion head 7 has at least four second through holes 23 with the same size as the first through hole 22. In this invention, the more second through holes 23 are provided, the more molds can be installed on the extrusion head 7. New second through holes 23 can be provided at the corresponding positions of the molds, thereby making the connection more stable when fixing the extrusion head 7. Since the half-thread screw 9 is compatible with the size of the first through hole 22 and the second through hole 23, the structural stability of the extrusion head 7 is further improved.

[0033] It is worth noting that a half-thread screw 9 is inserted inside the second through hole 23 and the first through hole 22, and the threaded end of the half-thread screw 9 is threaded with the threaded hole 21.

[0034] 6. The copper busbar production equipment according to claim 1, characterized in that: springs 12 are fixedly installed at both ends of the inner cavity of the lower telescopic tube 11, and the springs 12 are made of high-strength material. In this invention, when the copper busbar enters between the guide roller 15 and the conveyor belt 17, because the gap between the guide roller 15 and the conveyor belt 17 is at its minimum, the copper busbar will push the driven roller 16 and the conveyor belt frame 6 inside the conveyor belt 17 upwards, thereby squeezing the springs 12 inside the lower telescopic tube 11. Because the springs 12 have high strength, their reaction force can make the copper busbar and the guide roller 15 fit more tightly, making the copper busbar more stably fixed.

[0035] It is worth noting that the lower end of the L-shaped plate 3 is provided with a groove 19 for the lateral sliding of the upper telescopic tube 5. Inside the groove 19, two ends are rotatably fitted with screws 18 threaded to the fixed ends of the upper telescopic tube 5. An upper servo motor 4 is fixedly mounted on one end of the L-shaped plate 3, and the output shaft of the upper servo motor 4 passes through the L-shaped plate 3, is located within the groove 19, and is fixed to one end of the screws 18 via a coupling. In this invention, different bending dies 8 are selected depending on the size of the copper busbar. At this time, the appropriate extrusion head 7 die needs to be matched with it. The upper servo motor 4 receives a compiler signal, and its output shaft drives the screws 18 to rotate, thereby moving the upper telescopic tube 5 within the groove 19. After the extrusion head 7 die aligns with the bending die 8, the upper servo motor 4 stops working. At this time, hydraulic oil flows inside the hydraulic rod 20, causing the hydraulic rod 20 to work. The telescopic end of the hydraulic rod 20 extends and pushes the extrusion head 7 die to extrude and bend the copper busbar.

[0036] It is worth mentioning that a pressure sensor 24 is fixedly installed between the telescopic end of the upper telescopic tube 5 and the bracket 10. In this invention, when the telescopic end of the hydraulic rod 20 continues to extend, the pressure of the pressure sensor 24 increases and transmits the signal to the microcomputer controller through the wiring harness. The microcomputer controls the working state of the hydraulic rod 20 and the lower servo motor 14, thereby stopping the copper busbar conveying and then bending it, thus achieving the integrated copper busbar bending effect.

[0037] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
