Description

Technical Field

[0001] This invention relates to the field of copper busbar production technology, specifically to a bending device for copper busbar production. Background Technology

[0002] Copper busbars are a type of conductive material mainly used in the manufacture of motor windings, high and low voltage electrical appliances, switch contacts, and conductors for power supply and distribution installations. Copper busbars typically need to be bent according to different applications. However, copper busbars are generally bent using specific shaped pressure blocks and dies. In the current technology, the dies used for bending copper busbars are difficult to replace and adjust, making it difficult to quickly change the bending size of the copper busbars and making them inconvenient to use.

[0003] Patent CN218310551U discloses a bending device for copper busbar production. The patent includes a base, with a fixing block fixedly connected to the top of the base. A receiving groove is provided on one side of the fixing block, and a U-shaped block is slidably connected within the receiving groove. Brushes are adhered to the inner walls of both sides of the U-shaped block. A support frame is fixedly connected to one side of the U-shaped block, and a pull rod is slidably inserted into one side of the support frame. A connecting piece is fixedly connected to one end of the pull rod, and a spring is sleeved on one end of the pull rod. One end of the spring is fixedly connected to the connecting piece, and the other end of the spring is fixedly connected to the support frame. Two locking rods are fixedly connected to one side of the connecting piece, and the other end of the locking rods is inserted into the U-shaped block. The inner wall of one side of the fixed block is provided with multiple locking grooves, and the locking rods are engaged with the locking grooves. By the friction between the copper busbar and the brush, the dust particles on the copper busbar are cleaned to prevent the dust particles on the surface of the copper busbar from being damaged under the bending pressure. Although this patent solves the above problems, it still has the problem that it is difficult to quickly adjust the bending size of the copper busbar and is not convenient to use. Therefore, a bending device for copper busbar production is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a bending device for copper busbar production, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a bending device for copper busbar production, comprising a V-shaped bending base, a support frame fixedly connected to the upper surface of the V-shaped bending base, a hydraulic rod fixedly connected to the upper surface of the support frame, a V-shaped pressure block fixedly connected to the telescopic end of the hydraulic rod, V-shaped limiting plates fixedly connected to the front and rear sides of the upper surface of the V-shaped bending base, a first cross groove and a second cross groove opened on the inner side of the V-shaped bending base, threaded holes opened on both sides of the V-shaped bending base, and screws threadedly connected to the inner surface of the threaded holes, with the two V-shaped limiting plates slidably connected. The system includes a movable inclined plate (first type), with a cross plate (first type) fixedly connected to its lower surface. A movable inclined plate (second type) is slidably connected between the two V-shaped limiting plates, with a cross plate (second type) fixedly connected to its lower surface. A linear motor is fixedly connected to the left side of the V-shaped bending base, with a supporting inclined rod fixedly connected to its lower surface. A moving block is fixedly connected to the moving end of the linear motor, and a positioning clamp is hinged to the upper surface of the moving block. A supporting limiting device for limiting and clamping the copper busbar during transport is provided on the left side of the V-shaped bending base. An application tool for applying stretching oil and other additives to the surface of the copper busbar is also provided on the left side of the V-shaped bending base. The additive spraying device has a V-shaped pressure block whose outer surface is slidably connected to the inner surface of the support frame, a V-shaped limiting plate whose upper surface is fixedly connected to the lower surface of the support frame, a support inclined rod whose bottom end is fixedly connected to the left side of the V-shaped bending base, a cross plate one and a cross groove two whose inner surfaces are in contact with each other, a cross plate two and a cross groove one whose inner surfaces are in contact with each other, a screw and a cross plate one whose inner surfaces are rotatably connected, and a screw and a cross plate two whose inner surfaces are rotatably connected. The copper busbar to be bent is placed on the V-shaped bending base, and the hydraulic rod is activated. The hydraulic rod drives the V-shaped pressure block to descend. After the V-shaped pressure block contacts the copper busbar, it passes through its own V-shaped surface and the V-shaped surface of the V-shaped bending base. When bending the copper busbar, to change the bending size, rotate the screw. The screw moves left and right through the threaded groove in the threaded hole, causing the movable inclined plate 1 and movable inclined plate 2 to move closer or further apart. When movable inclined plate 1 and movable inclined plate 2 move closer together, they cause cross plate 1 and cross plate 2 to cross each other and insert into cross groove 1 and cross groove 2. When movable inclined plate 1 and movable inclined plate 2 move further apart, they cause cross plate 1 and cross groove 2 to move further apart. Start the linear motor, which drives the moving block to the left end. At this time, insert the left end of the copper busbar into the positioning clamp and fix it. Then, the linear motor drives the moving block and positioning clamp to move to the right, so that the copper busbar moves under the V-shaped pressure block.

[0006] Preferably, the support and limiting device includes a first limiting seat, a connecting column, a second limiting seat, a sliding rod, and a flexible semi-clamp. The first limiting seat is fixedly connected to the left side of the V-shaped bent base, the connecting column is fixedly connected to the left side of the first limiting seat, the second limiting seat is fixedly connected to the left end of the connecting column, the sliding rod is slidably connected to the inner surface of the second limiting seat, and the flexible semi-clamp is fixedly connected to the end of the sliding rod near the second limiting seat. The support and limiting device also includes a pressure plate, an abutting inclined plate, a limiting guide rail, a trapezoidal push plate, and a connecting inclined plate. The pressure plate is fixedly connected to the left side of the base. The sliding rod is fixedly connected to the end away from the second limiting seat. The abutting inclined plate is fixedly connected to the left side of the pressure plate. The limiting guide rail is fixedly connected to the side of the pressure plate away from the second limiting seat. The connecting inclined plate is fixedly connected to the front and rear sides of the moving block. The trapezoidal push plate is fixedly connected to the top of the connecting inclined plate. The circumferential surface of the sliding rod is slidably connected to the inner surface of the first limiting seat. A spring is provided between the pressure plate and the second limiting seat. A spring is provided between the pressure plate and the first limiting seat. The inclined surface of the trapezoidal push plate is in contact with the inclined surface of the abutting inclined plate. The upper and lower sides and the inner surface of the limiting guide rail are in contact with each other. The positioning hoop drives the copper busbar to move to the right and insert into the limiting seat 2 and the limiting seat 1. By pushing the slide rod, the slide rod drives the flexible semi-clamp to contact the copper busbar. When the moving block moves to the right, it drives the connecting inclined plate to move to the right. The connecting inclined plate drives the trapezoidal push plate to move to the right and slide between the limiting guide rails. When the trapezoidal push plate moves to the right, it pushes the abutting inclined plate closer to the limiting seat 2 through the guide of the inclined surface. The abutting inclined plate drives the pressure plate closer to the limiting seat 1 and the limiting seat 2. The pressure plate drives the slide rod to move between the limiting seat 1 and the limiting seat 2. The limit seat slides inward and approaches the copper busbar. The slide rod then drives the flexible semi-clamp to approach the copper busbar, so that the flexible semi-clamp automatically supports the copper busbar. Through the flexible deformation of the flexible semi-clamp, it can deform when it touches copper busbars of different diameters. When the moving block moves to the left, it drives the connecting inclined plate and the trapezoidal push plate to move to the left. At this time, the contacting inclined plate and the pressure plate lose the contact of the trapezoidal push plate, so that the elastic reset action of the spring drives the pressure plate to reset, thereby causing the slide rods to move away from each other. The slide rod then drives the flexible semi-clamps to move away from each other.

[0007] Preferably, the additive spraying device includes an upper connecting seat, a lower connecting seat, a fixed plate, an elastic liquid reservoir, and a three-way spray pipe. The upper connecting seat is fixedly connected to the circumferential surface of the connecting column, the lower connecting seat is fixedly connected to the circumferential surface of the connecting column, the fixed plate is fixedly connected to the upper surface of the upper connecting seat, the elastic liquid reservoir is fixedly connected to the side of the fixed plate near the pressure plate, and the three-way spray pipe is rotatably connected to the lower surface of the elastic liquid reservoir. The additive spraying device also includes a rotating shaft, rollers, applicator cotton, connecting plate, clamping rod, and extrusion shaft. The rotating shaft is fixedly connected to the lower surface of the upper connecting seat, the rollers are rotatably connected to the circumferential surface of the rotating shaft, the applicator cotton is fixedly connected to the circumferential surface of the rollers, the connecting plate is fixedly connected to the upper surface of the pressure plate, the clamping rod is fixedly connected to the side of the connecting plate near the elastic liquid reservoir, and the extrusion shaft is fixedly connected to the side of the clamping rod away from the connecting plate. One end of the plate, the top of the rotating shaft and the upper surface of the lower connecting seat are fixedly connected. The side of the extrusion shaft away from the clamping rod is in contact with the elastic accumulator. When the copper busbar is inserted between the first and second limiting seats, the three-way nozzle is rotated to make the nozzle align with the copper busbar, and then the elastic accumulator is extruded. After being compressed, the elastic accumulator sprays the internal stretching oil onto the surface of the copper busbar. When the pressure plate approaches the first and second limiting seats, it drives the connecting plate to approach the elastic accumulator. The connecting plate drives the extrusion shaft to approach and extrude the elastic accumulator through the clamping rod. The three-way nozzle is rotated to make the nozzle align with the coating cotton. Then the three-way nozzle sprays the stretching oil onto the coating cotton. During the process of moving to the right, the copper busbar contacts the coating cotton and generates friction. The coating cotton is affected by the friction and rotates on the rotating shaft through the roller, so that the stretching oil sprayed onto the coating cotton is evenly coated onto the surface of the copper busbar.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This bending device for copper busbar production uses a V-shaped pressure block to bend the copper busbar through its own V-shaped surface and the V-shaped bending base after contact with the copper busbar. The movable inclined plate one and movable inclined plate two move away from each other, thereby changing the bottom support area of ​​the copper busbar and thus changing the bending size produced by the V-shaped pressure block after pressing the copper busbar. This improves the applicability of the device. The positioning hoop moves the copper busbar under the V-shaped pressure block, eliminating the need for manual placement of the copper busbar under the V-shaped pressure block and improving safety during use.

[0010] 2. The bending device for copper busbar production features a flexible semi-clamp that contacts the copper busbar, increasing the support area during busbar movement and preventing deviation of the busbar during movement, which would lead to bending angle deviation and improve bending accuracy. The flexible semi-clamp automatically supports the copper busbar, and through its flexible deformation, it can deform when it touches copper busbars of different diameters, thus supporting them and improving the device's applicability. The sliding rod moves the flexible semi-clamps away from each other, preventing larger diameter copper busbars from being blocked by the flexible semi-clamps during rightward movement.

[0011] 3. The bending device for copper busbar production uses an elastic accumulator that, under pressure, sprays the internal stretching oil onto the surface of the copper busbar, reducing abrasion during bending, minimizing metal fatigue, and improving the processing quality of the copper busbar. The extrusion shaft approaches and squeezes the elastic accumulator, causing the stretching oil inside to be automatically sprayed onto the surface of the copper busbar, improving ease of use. The stretching oil on the applicator is evenly applied to the surface of the copper busbar, further enhancing the protective effect of the stretching oil and improving the processing quality of the copper busbar.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-8One embodiment of the present invention is as follows: a bending device for copper busbar production, comprising a V-shaped bending base 1, a support frame 2 fixedly connected to the upper surface of the V-shaped bending base 1, a hydraulic rod 3 fixedly connected to the upper surface of the support frame 2, a V-shaped pressure block 4 fixedly connected to the telescopic end of the hydraulic rod 3, V-shaped limiting plates 41 fixedly connected to the front and rear sides of the upper surface of the V-shaped bending base 1, a cross groove 42 and a cross groove 43 formed on the inner side of the V-shaped bending base 1, and threaded holes 44 formed on both sides of the V-shaped bending base 1, with the inner surface of the threaded holes 44 threadedly connected to... There is a screw 45, a movable inclined plate 46 slidably connected between two V-shaped limiting plates 41, a cross plate 47 fixedly connected to the lower surface of the movable inclined plate 46, a movable inclined plate 48 slidably connected between the two V-shaped limiting plates 41, a cross plate 49 fixedly connected to the lower surface of the movable inclined plate 48, a linear motor 410 fixedly connected to the left side of the V-shaped bending base 1, a supporting inclined rod 411 fixedly connected to the lower surface of the linear motor 410, a moving block 412 fixedly connected to the moving end of the linear motor 410, and a positioning clamp 413 hinged to the upper surface of the moving block 412. The V-shaped pressure... After block 4 contacts the copper busbar, it bends the copper busbar through its own V-shaped surface and the V-shaped surface of the V-shaped bending base 1. A support limiting device 5 for limiting and clamping the copper busbar during transport is provided on the left side of the V-shaped bending base 1. An additive spraying device 6 for applying stretching oil and other additives to the surface of the copper busbar is also provided on the left side of the V-shaped bending base 1. The outer surface of the V-shaped pressure block 4 and the inner surface of the support frame 2 are slidably connected. The upper surface of the V-shaped limiting plate 41 and the lower surface of the support frame 2 are fixedly connected. The bottom end of the support diagonal rod 411 is fixedly connected to the left side of the V-shaped bending base 1. The cross plate 47 and the cross... The inner surfaces of the fork slot 43 are in contact with each other, the inner surfaces of the cross plate 49 and the cross slot 42 are in contact with each other, the screw 45 and the inner surface of the cross plate 47 are rotatably connected, the screw 45 and the inner surface of the cross plate 49 are rotatably connected, and the movable inclined plate 46 and the movable inclined plate 48 are far apart from each other, thereby changing the bottom support area of ​​the copper busbar, and thus changing the bending size of the copper busbar after the V-shaped pressure block 4 presses it, improving the applicability of the device. The positioning hoop 413 drives the copper busbar to move under the V-shaped pressure block 4, eliminating the need for manual placement of the copper busbar under the V-shaped pressure block 4, thus improving the safety of use.

[0023] Working principle: Place the copper busbar to be bent on the V-shaped bending base 1. Activate the hydraulic rod 3, which drives the V-shaped pressure block 4 to descend. After contacting the copper busbar, the V-shaped pressure block 4 bends the copper busbar through its own V-shaped surface and the V-shaped surface of the V-shaped bending base 1. When the bending size of the copper busbar needs to be changed, rotate the screw 45. The screw 45 moves left and right through the threaded groove in the threaded hole 44, causing the movable inclined plate 1 46 and movable inclined plate 2 48 to move closer or further apart. When the movable inclined plate 1 46 and movable inclined plate 2 48 move closer together, they cause the cross plate 1 47 and cross plate 2 49 to cross each other and insert into the cross groove 1 42 and cross groove 2 43. When the first movable inclined plate 46 and the second movable inclined plate 48 move away from each other, they also cause the first cross plate 47 and the second cross plate 49 to move away from each other, thereby changing the bottom support area of ​​the copper busbar. This changes the bending size of the copper busbar after the V-shaped pressure block 4 presses it, improving the applicability of the device. The linear motor 410 is started, and the linear motor 410 drives the moving block 412 to move to the left end. At this time, the left end of the copper busbar is inserted into the positioning hoop 413 for fixation. Then, the linear motor 410 drives the moving block 412 and the positioning hoop 413 to move to the right, so that the copper busbar is moved under the V-shaped pressure block 4. There is no need to manually place the copper busbar under the V-shaped pressure block 4, which improves the safety of use.

[0024] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the supporting limiting device 5 includes a limiting seat 51, a connecting column 52, a limiting seat 53, a sliding rod 54, and a flexible semi-clamp 55.

At the end of the slide rod 54 near the second limiting seat 53, the flexible semi-clamp 55 contacts the copper busbar, increasing the support area when the copper busbar moves, preventing the copper busbar from shifting during movement, which would lead to a shift in the bending angle and improve the bending accuracy. The supporting limiting device 5 also includes a pressure plate 56, an abutting inclined plate 57, a limiting guide rail 58, a trapezoidal push plate 59, and a connecting inclined plate 510. The pressure plate 56 is fixedly connected to the end of the slide rod 54 away from the second limiting seat 53, and the abutting inclined plate 57 is fixedly connected to the pressure plate 56. On the left side of plate 56, the limiting guide rail 58 is fixedly connected to the side of pressure plate 56 away from limiting seat 2 53. The connecting inclined plate 510 is fixedly connected to the front and rear sides of the moving block 412. The trapezoidal push plate 59 is fixedly connected to the top of the connecting inclined plate 510. The circumferential surface of the slide rod 54 is slidably connected to the inner surface of limiting seat 1 51. A spring is provided between pressure plate 56 and limiting seat 2 53. A spring is provided between pressure plate 56 and limiting seat 1 51. The inclined surface of the trapezoidal push plate 59 is in contact with the inclined surface of the contacting inclined plate 57. The upper and lower sides of the trapezoidal push plate 59 and the inner surface of the limiting guide rail 58 are in contact with each other. The flexible semi-clamp 55 automatically supports the copper busbar. Through the flexible deformation of the flexible semi-clamp 55, it can deform when it touches copper busbars of different diameters, thereby supporting copper busbars of different diameters and improving the applicability of the device. The slide rod 54 drives the flexible semi-clamps 55 to move away from each other, preventing copper busbars with larger diameters from being blocked by the flexible semi-clamps 55 during the movement to the right.

[0025] Working principle: The positioning clamp 413 drives the copper busbar to move to the right and inserts it into the limiting seat 2 53 and the limiting seat 1 51. By pushing the slide rod 54, the slide rod 54 drives the flexible semi-clamp 55 to contact the copper busbar, increasing the support area of ​​the copper busbar during movement and preventing the copper busbar from shifting during movement, which would lead to the deviation of the bending angle and improve the bending accuracy. When the moving block 412 moves to the right, it drives the connecting inclined plate 510 to move to the right. The connecting inclined plate 510 drives the trapezoidal push plate 59 to move to the right and slide between the limiting guide rails 58. When the trapezoidal push plate 59 moves to the right, it pushes the abutting inclined plate 57 closer to the limiting seat 2 53 through the guide of the inclined surface. The abutting inclined plate 57 drives the pressure plate 56 closer to the limiting seat 1 51 and the limiting seat 2 53. The pressure plate 56 drives the slide rod 54 to move between the limiting seat 1 51 and the limiting guide rails 58. The slide bar 53 slides inward and approaches the copper busbar. The slide bar 54 then drives the flexible semi-clamp 55 to approach the copper busbar, so that the flexible semi-clamp 55 automatically supports the copper busbar. Through the flexible deformation of the flexible semi-clamp 55, it can deform when it touches copper busbars of different diameters, thereby supporting copper busbars of different diameters and improving the applicability of the device. When the moving block 412 moves to the left, it drives the connecting inclined plate 510 and the trapezoidal push plate 59 to move to the left. At this time, the contacting inclined plate 57 and the pressure plate 56 lose the contact of the trapezoidal push plate 59, so that the elastic reset action of the spring drives the pressure plate 56 to reset, thereby causing the slide bar 54 to move away from each other. The slide bar 54 then drives the flexible semi-clamp 55 to move away from each other, preventing the copper busbar with a larger diameter from being blocked by the flexible semi-clamp 55 during the movement to the right.

[0026] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the additive spraying device 6 includes an upper connecting seat 61, a lower connecting seat 62, a fixing plate 63, an elastic liquid storage bag 64, and a three-way spray pipe 65. The upper connecting seat 61 is fixedly connected to the circumferential surface of the connecting column 52, the lower connecting seat 62 is fixedly connected to the circumferential surface of the connecting column 52, the fixing plate 63 is fixedly connected to the upper surface of the upper connecting seat 61, the elastic liquid storage bag 64 is fixedly connected to the side of the fixing plate 63 near the pressure plate 56, and the three-way spray pipe 65 is rotatably connected to the lower surface of the elastic liquid storage bag 64. After being pressed, the elastic liquid storage bag 64 sprays the internal stretching oil onto the surface of the copper busbar, reducing the abrasion generated during the bending process of the copper busbar, reducing metal fatigue, and improving the processing quality of the copper busbar. The additive spraying device 6 also includes a rotating shaft 66, a roller 67, an applicator cotton 68, a connecting plate 69, a clamping rod 610, and a pressing shaft 611. A rotating shaft 66 is fixedly connected to the lower surface of the upper connecting seat 61. A roller 67 is rotatably connected to the circumferential surface of the rotating shaft 66. An applicator 68 is fixedly connected to the circumferential surface of the roller 67. A connecting plate 69 is fixedly connected to the upper surface of the pressure plate 56. A clamping rod 610 is fixedly connected to the side of the connecting plate 69 near the elastic reservoir 64. A pressing shaft 611 is fixedly connected to the end of the clamping rod 610 away from the connecting plate 69. The top of the rotating shaft 66 is fixedly connected to the upper surface of the lower connecting seat 62. The side of the pressing shaft 611 away from the clamping rod 610 is in contact with the elastic reservoir 64. The pressing shaft 611 approaches and presses the elastic reservoir 64, so that the stretching oil in the elastic reservoir 64 is automatically sprayed onto the surface of the copper busbar, improving ease of use. The stretching oil on the applicator 68 is evenly applied to the surface of the copper busbar, thereby improving the protective effect of the stretching oil on the copper busbar and further improving the processing quality of the copper busbar.

[0027] Working principle: When the copper busbar is inserted between limit seat 1 51 and limit seat 2 53, the three-way nozzle 65 is rotated to align the nozzle with the copper busbar, and then the elastic accumulator 64 is squeezed. After being compressed, the elastic accumulator 64 sprays the internal stretching oil onto the surface of the copper busbar, reducing the abrasion generated during the bending process of the copper busbar, reducing metal fatigue, and improving the processing quality of the copper busbar. When the pressure plate 56 approaches the limit seat 1 51 and limit seat 2 53, it drives the connecting plate 69 to approach the elastic accumulator 64. The connecting plate 69 drives the extrusion shaft 611 to approach and squeeze the elastic accumulator 64 through the clamping rod 610. This allows the stretching oil in the elastic reservoir 64 to be automatically sprayed onto the surface of the copper busbar, improving ease of use. By rotating the three-way nozzle 65, the nozzle is aligned with the coating cotton 68, and then the three-way nozzle 65 sprays the stretching oil onto the coating cotton 68. As the copper busbar moves to the right, it comes into contact with the coating cotton 68 and generates friction. The coating cotton 68 is affected by the friction and rotates on the rotating shaft 66 via the roller 67, thereby evenly coating the stretching oil sprayed onto the coating cotton 68 onto the surface of the copper busbar, thus improving the protective effect of the stretching oil on the copper busbar and further improving the processing quality of the copper busbar.
