Description

Technical Field

[0001] This invention relates to the field of corner bending machine technology, and more particularly to a material changing mechanism for a corner bending machine. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four main types: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles. Promoting new energy vehicles is necessary to address environmental protection and the oil crisis, reducing or abandoning current mainstream models that burn traditional gasoline or diesel engines. The production process of existing new energy vehicle power batteries requires the use of a folding machine to fold the tin foil on the outer wall of the power battery.

[0003] In the use of existing corner bending machines for the production of new energy vehicle power batteries, it has been found that some corner bending machines still use manual feeding and discharging methods. In order to ensure production efficiency, the speed of feeding and discharging materials is very fast. Since the cylinder is located directly above the work area, the operators need to maintain a high level of concentration at all times. Otherwise, safety accidents are very likely to occur. At the same time, the long-term high concentration work has a huge impact on human function, causing operator fatigue and creating great safety hazards when changing materials. Based on the above problems, this application proposes a material changing mechanism for corner bending machines. Summary of the Invention

[0008] Preferably, the material changing assembly includes a fixing plate, which is fixedly installed on the rear side of the mounting plate. A mounting block is fixedly installed at the bottom of the fixing plate, and a mounting shaft is fixedly installed on one side of the mounting block. A flipping push plate is rotatably installed on the surface of the mounting shaft, and a connecting shaft is rotatably installed inside the flipping push plate. Limiting rings are fixedly installed on the surfaces of both the connecting shaft and the mounting shaft, and the limiting rings are in contact with the flipping push plate. A mounting column is fixedly installed at the end of the connecting shaft away from the limiting ring. A guide sleeve is fixedly installed at the bottom of the mounting column, and a guide rail is slidably installed inside the guide sleeve. The guide rail is fixedly installed on the lower side wall of the mounting frame.

[0010] Preferably, the sealing assembly includes a rectangular sleeve fixedly installed on the side of the storage bin, a rectangular slider slidably disposed inside the rectangular sleeve, a return spring connected between the front side of the rectangular slider and the front sidewall of the rectangular sleeve, a rectangular moving column fixedly disposed on the rear side of the rectangular slider, a connecting block fixedly disposed at the rear end of the rectangular moving column, a rectangular plate fixedly disposed between the facing surfaces of the connecting blocks, a sealing plate fixedly disposed on the front side of the rectangular plate, and the top of the sealing plate overlapping the bottom of the storage bin.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The material changing mechanism of this corner bending machine works by driving the material changing plate in the material changing component to move backward when the corner bending component closes the mold to bend the sheet metal. When the corner bending component closes the mold, the bending component drives the material changing plate in the material changing component to move forward, so that the material changing plate pushes the sheet metal that does not need to be bent into the lower mold. Moreover, by continuously bending the sheet metal by the corner bending component, the material changing component can continuously drive the sheet metal into the corner bending component and push out the formed sheet metal in the corner bending component. Therefore, there is no need for manual loading and unloading of the corner bending machine, making the corner bending machine more convenient to use.

[0016] 2. The material changing mechanism of the corner bending machine drives the sealing plate in the sealing component to move backward when the material changing component moves backward, so that the material in the storage box falls to the top of the placement plate. Moreover, when the material changing plate in the material changing component moves forward, the sealing plate in the sealing component will move forward with the material changing plate due to the rebound of the return spring, thereby sealing the bottom of the storage box and preventing the material from falling out of the storage box when the material changing plate reaches the predetermined position.

[0017] 3. The material changing mechanism of the corner bending machine weighs the material in the storage bin when the material is consumed. The weight of the material is weighed by the weighing component and the quantity of material in the storage bin is displayed by emitting different colored lights. This allows the quantity of material in the storage bin to be observed, so that the material can be replenished in time when the material is too low, thus avoiding the situation where the corner bending component cannot work due to the depletion of material.

[0027] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 1-8A material changing mechanism for a corner bending machine includes a mounting frame 1. A corner bending component is mounted on the surface of the mounting frame 1 for bending sheet metal. A weighing component is mounted on the lower side wall of the mounting frame 1. A placement plate 20 is mounted inside the mounting frame 1 via the weighing component. A U-shaped plate 21 is fixedly mounted on the side of the placement plate 20. A storage bin 22 is fixedly mounted between the facing surfaces of the U-shaped plates 21. A sealing component is mounted on the surface of the storage bin 22 for sealing the bottom opening of the storage bin 22. A material changing component is mounted above the mounting frame 1 for changing the corner bending component. For feeding and unloading, when the cornering component closes the mold to bend the sheet metal, the cornering component drives the material changing plate 19 in the material changing component to move backward. When the cornering component opens the mold, the bending component drives the material changing plate 19 in the material changing component to move forward, so that the material changing plate 19 pushes the sheet metal that does not need to be bent into the lower mold 5. Moreover, by continuously bending the sheet metal with the cornering component, the material changing component can continuously drive the sheet metal into the cornering component and push out the formed sheet metal in the cornering component. Therefore, there is no need for manual feeding and unloading of the cornering machine, making the cornering machine more convenient to use.

[0029] Specifically, the angle-bending assembly includes a hydraulic push rod 2 fixedly installed on the top of the mounting frame 1. A mounting plate 3 is fixedly installed at the output end of the hydraulic push rod 2. A bending head 4 is fixedly installed at the bottom of the mounting plate 3. A lower mold 5 is installed below the bending head 4 and is fixedly installed on the lower side wall of the mounting frame 1. Guide rings 6 are fixedly installed on both the left and right sides of the mounting plate 3. Guide posts 7 are slidably installed inside the guide rings 6 and are fixedly installed inside the mounting frame 1. Buffer rings 8 are slidably installed on the surface of the guide posts 7. A buffer spring 9 connects the bottom of the buffer ring 8 and the lower side wall of the mounting frame 1. The material-changing assembly includes a fixing plate 10, which is fixedly installed on the rear side of the mounting plate 3. A mounting block 11 is fixedly installed at the bottom of the 10. A mounting shaft 12 is fixedly installed on one side of the mounting block 11. A flipping push plate 13 is rotatably installed on the surface of the mounting shaft 12. A connecting shaft 14 is rotatably installed inside the flipping push plate 13. There are two flipping push plates 13, which are symmetrically distributed. A connecting hole for connecting with the mounting shaft 12 and the connecting shaft 14 is provided through the surface of the flipping push plate 13. The flipping push plate 13 is made of metal. Limiting rings 15 are fixedly installed on the surfaces of both the connecting shaft 14 and the mounting shaft 12. The limiting rings 15 are in contact with the flipping push plate 13. A mounting post 16 is fixedly installed at the end of the connecting shaft 14 away from the limiting ring 15. A guide sleeve 17 is fixedly installed at the bottom of the mounting column 16. A guide rail 18 is slidably installed inside the guide sleeve 17. The guide rail 18 is fixedly installed on the lower side wall of the mounting frame 1. A material exchange plate 19 is connected between the facing surfaces of the mounting columns 16. The material exchange plate 19 overlaps the top of the placement plate 20. The hydraulic push rod 2 drives the guide ring 6 to slide on the surface of the guide column 7 through the mounting plate 3, and drives the bending head 4 to move downward. The guide ring 6 is buffered by the buffer ring 8 and the buffer spring 9, so that the mounting plate 3 buffers the bending head 4, and the bending head 4 cooperates with the lower mold 5 to bend the plate. Moreover, the mounting plate 3 will drive the mounting block 11 to move downward through the fixing plate 10. This causes the mounting shaft 12 to move by pushing the connecting shaft 14 through the flipping push plate 13, causing the mounting column 16 to drive the guide sleeve 17 to slide on the surface of the guide rail 18. When the material changing plate 19 is removed from the bottom of the storage box 22, the plate material in the storage box 22 falls to the top of the placement plate 20. When the bending head 4 and the lower mold 5 are separated, the mounting plate 3 drives the mounting block 11 to reset through the fixing plate 10, causing the mounting shaft 12 to move the connecting shaft 14 forward through the flipping push plate 13, causing the material changing plate 19 to push the plate material that has fallen to the top of the placement plate 20 to move to the top of the lower mold 5. By repeating the above operation, the corner component can be continuously changed, thereby bending the corner of the plate material.

[0030] Specifically, the weighing assembly includes a U-shaped plate 23 fixedly installed at the bottom of the placement plate 20. A connecting stud 24 is interlocked inside the U-shaped plate 23, and a limit nut 25 is threaded on the surface of the connecting stud 24. A weighing sensor 26 is fixedly installed at the bottom of the connecting stud 24 and is fixedly installed on the lower side wall of the mounting frame 1. A support plate 39 is installed above the U-shaped plate 23 and is fixedly installed on the right side of the storage bin 22. A multi-color indicator light 27 is fixedly installed on the top of the support plate 39. After the material changing plate 19 is reset, the weight of the material inside the storage bin 22 is directly applied to the placement plate 20 through the U-shaped plate 21, and the weight is transferred to the placement plate 20. The weight is applied to the shaped plate 23, which, through the connecting stud 24 and the limiting nut 25, applies the weight to the detection end of the weighing sensor 26. The weighing sensor 26 measures the weight of the plates inside the storage bin 22. Since the weight of plates of the same specification is basically the same, the quantity of plates inside the storage bin 22 can be calculated by weight. The multi-color indicator light 27 emits different colored lights to show the quantity of plates inside the storage bin 22. This allows for timely replenishment of plates inside the storage bin 22 when the quantity of plates is too low, ensuring the quantity of plates inside the storage bin 22 and preventing the corner assembly from malfunctioning due to the depletion of plates inside the storage bin 22.

[0031] Specifically, the sealing assembly includes a rectangular sleeve 28 fixedly installed on the side of the storage bin 22. A rectangular slider 29 is slidably disposed inside the rectangular sleeve 28. A return spring 30 is connected between the front side of the rectangular slider 29 and the front sidewall of the rectangular sleeve 28. A rectangular moving column 31 is fixedly disposed on the rear side of the rectangular slider 29. A connecting block 32 is fixedly disposed at the rear end of the rectangular moving column 31. A rectangular plate 33 is fixedly disposed between the facing surfaces of the connecting blocks 32. A sealing plate 34 is fixedly disposed on the front side of the rectangular plate 33. The top of the sealing plate 34 overlaps with the bottom of the storage bin 22. The material changing plate 19 pushes the sealing plate 34 to move rearward, and the rectangular plate 33 is moved rearward by the sealing plate 34. Plate 33 drives connecting block 32 to move rearward, causing connecting block 32 to drive rectangular moving column 31 to move inside rectangular sleeve 28. Then, rectangular moving column 31 drives rectangular slider 29 to stretch reset spring 30, causing sealing plate 34 to move away from bottom of storage box 22. This allows the material in storage box 22 to fall to top of placement plate 20. Material changing plate 19 pushes the material that has fallen to top of placement plate 20 to move to lower mold 5. Moreover, reset spring 30 pushes rectangular moving column 31 forward through rectangular slider 29, causing connecting block 32 to reset sealing plate 34 through rectangular plate 33, so that sealing plate 34 seals bottom of placement plate 20.

[0032] Specifically, a discharge assembly is provided on the lower side wall of the mounting frame 1. The discharge assembly includes a fixed base plate 35 fixedly installed on the lower side wall of the mounting frame 1. A rectangular column 36 is fixedly installed on the top of the fixed base plate 35. A discharge plate 37 is fixedly installed on the top of the rectangular column 36. A protective pad 38 is fixedly installed inside the discharge plate 37. The discharge plate 37 has a U-shaped structure and is inclined. The protective pad 38 has a rectangular structure and is made of elastic rubber. When the plate material enters the lower mold 5, the corner-shaped plate material will be pushed out from the lower mold 5 and fall into the discharge plate 37, so that the corner-shaped plate material comes into contact with the protective pad 38. The protective pad 38 protects the corner-shaped plate material that falls into the discharge plate 37. The corner-shaped plate material slides into the external collection box through the protective pad 38, which facilitates the collection of the corner-shaped plate material and facilitates the centralized transportation of the corner-shaped plate material in the future.

[0033] In use: The hydraulic push rod 2 drives the output end to move the mounting plate 3 downward. The mounting plate 3 drives the guide ring 6 to slide on the surface of the guide post 7, and the mounting plate 3 drives the bending head 4 downward. When the bending head 4 contacts the plate, the guide ring 6 first contacts the buffer ring 8. The guide ring 6 pushes the buffer ring 8 to compress the buffer spring 9. The buffer ring 8 and the buffer spring 9 buffer the guide ring 6, thereby allowing the mounting plate 3 to buffer the bending head 4. The bending head 4 then cooperates with the lower die 5 to bend the plate at an angle. The mounting plate 3 also drives the fixing plate 10 downward, causing the fixing plate 10 to bend downward. Plate 10 drives mounting block 11 to move downwards, which in turn drives mounting shaft 12 to move downwards. Mounting shaft 12 then pushes the top of flipping push plate 13 downwards. The bottom of flipping push plate 13 pushes connecting shaft 14, causing connecting shaft 14 to push mounting column 16, which in turn pushes material changing plate 19 to move rearwards. Mounting column 16 then drives guide sleeve 17 to slide on guide rail 18, allowing guide sleeve 17 and guide rail 18 to limit and guide mounting column 16. This causes material changing plate 19 to push sealing plate 34 rearwards, and the sealing plate 34, along with its moving rectangular plate 33, moves rearwards. The rectangular plate 33 moves to the side, and the connecting block 32 moves to the rearward side, causing the connecting block 32 to move the rectangular moving column 31 inside the rectangular sleeve 28. Then, the rectangular moving column 31 drives the rectangular slider 29 to stretch the return spring 30, causing the sealing plate 34 to move away from the bottom of the storage box 22. When the material changing plate 19 moves away from the bottom of the storage box 22, the material in the storage box 22 falls to the top of the placement plate 20. When the bending head 4 and the lower mold 5 separate, the mounting plate 3 drives the mounting block 11 to reset through the fixing plate 10, so that the mounting shaft 12 drives the connecting shaft 14 forward through the flipping push plate 13. Lateral movement: the connecting shaft 14 drives the material changing plate 19 to move forward through the mounting column 16, and drives the guide sleeve 17 to slide forward on the surface of the guide rail 18 through the mounting column 16, so that the material changing plate 19 pushes the plate that falls to the top of the placement plate 20 to move to the top of the lower mold 5. Moreover, the return spring 30 pushes the rectangular moving column 31 to move forward through the rectangular slider 29, so that the connecting block 32 drives the sealing plate 34 to reset through the rectangular plate 33, so that the sealing plate 34 seals the bottom of the placement plate 20. By repeating the above operation, the corner component can be continuously changed, thereby folding the corners of the plate.
