[0023] like Figures 1 to 5As shown, a sheet metal cutting and bending device includes a mold frame assembly 1, a drive assembly 2, a bending assembly 3, and a cutting assembly 4; the drive assembly 2 includes a movable plate 21, a first drive device 22, and a second drive device 23, the first drive device 22 and the second drive device 23 being fixedly mounted on the mold frame assembly 1; the output end of the first drive device 22 is fixedly connected to the movable plate 21, and the first drive device 22 drives the movable plate 21 to move up and down; The cutting assembly 4 includes a fixed plate 41, a lower cutter 42, and an upper cutter 43. The fixed plate 41 is fixedly mounted on the mold frame assembly 1. The lower cutter 42 is fixedly mounted on the fixed plate 41. The upper cutter 43 is fixedly mounted on the movable plate 21. The upper cutter 43 is located above the lower cutter 42, and the cutting end of the upper cutter 43 faces the lower cutter 42. The bending assembly 3 includes a bending die base plate 31, a movable seat 32, a lower bending template 33, a lower bending cutter 34, and an upper bending cutter 35. The bending die base plate 31 is fixedly mounted on the mold frame assembly 1. The lower bending template 33 is fixedly mounted on the bending die base plate 31. The movable seat 32 is movably connected to the lower bending template 33. The lower bending cutter 34 is fixedly mounted on the movable seat 32. The output end of the second driving device 23 is fixedly connected to the movable seat 32. The second driving device 23 drives the movable seat 32 to move up and down. The upper bending blade 35 is fixedly mounted on the movable plate 21. The upper bending blade 35 is correspondingly mounted to the lower bending template 33. The upper bending blade 35 is located above the lower bending blade 34, and the upper bending blade 35 is located on the side of the lower bending blade 34 away from the cutting assembly 4. A bending gap 5 is formed between the end face of the lower bending template 33 facing the lower bending blade 34 and the cutting end of the upper cutting blade 43.

[0024] The sheet metal cutting and bending device is used to process sheet metal 8, and the length of sheet metal 8 can be the length required to manufacture multiple sheets, such as... Figure 5 As shown, in the long board material 8 (the board material 8 shown in the figure can be cut to obtain two boards; the actual length of the board material 8 in processing can be the length that yields more boards), cutting is usually performed between the boards to be formed to obtain multiple boards. In the board material 8 shown in the figure, there is a cutting point 81 and a rear bending point 82 between the two boards to be formed. During processing, as... Figure 1As shown, the sheet material 8 is conveyed from back to front. Using an existing feeding conveyor, the sheet material 8 can be fed to the sheet material cutting and bending device. The sheet material 8 is conveyed along the feeding direction (from back to front) to the bending assembly 3 and the cutting assembly 4. The driving assembly 2 drives the bending assembly 3 and the cutting assembly 4 to move, simultaneously cutting and bending the sheet material 8. During cutting and bending of the sheet material 8, the first driving device 22 drives the movable plate 21 to move downwards. The movable plate 21 simultaneously drives the upper cutting blade 43 and the upper bending blade 35 to move downwards. The upper cutting blade 43 moves downwards until its cutting end is tangent to the cutting end of the lower cutting blade 42. With the cooperation of the upper cutting blade 43 and the lower cutting blade 42, the sheet material 8 is cut. When the upper bending blade 35 moves downward, since the upper bending blade 35 is correspondingly set with the lower bending template 33, the upper bending blade 35 presses the sheet metal 8 tightly against the upper end face of the lower bending template 33. The second driving device 23 synchronously drives the movable seat 32 to move upward, and the movable seat 32 drives the lower bending blade 34 to move upward. Since the upper bending blade 35 is located on the side of the lower bending blade 34 away from the cutting component 4, that is, the lower bending blade 34 is located on the side of the rear bending point 82 of the sheet metal 8 close to the cut-out point, when the lower bending blade 34 moves upward, since the cutting and bending are synchronous, when the sheet metal 8 is cut, the upward movement of the lower bending blade 34 immediately realizes the upward folding of the sheet metal 8 between the cut-out point 81 and the rear bending point 82 from back to front, thereby realizing the bending of the sheet metal 8. After one cutting and bending is completed, a processed board is obtained. It continues to be conveyed forward by the feeding conveyor to continue cutting and bending the cutting point 81 between the two boards to be formed and the bending point 82 at the rear end of the long board 8, so as to realize the cutting and bending processing of multiple boards.

[0025] Specifically, a bending gap 5 is formed between the end face of the lower bending template 33 facing the lower bending blade 34 and the cutting end of the upper cutting blade 43. After the upper cutting blade 43 cuts the sheet material 8, the sheet material 8 located between the cutting end of the upper cutting blade 43 and the end face of the lower bending template 33 facing the lower bending blade 34 is the part that needs to be bent.

[0026] To further explain, since the bending upper blade 35 and the upper cutting blade 43 are respectively fixedly mounted on the movable plate 21, when the movable plate 21 is driven to move downward by the first driving device 22, the bending upper blade 35 and the upper cutting blade 43 can be driven to move downward simultaneously. With the cooperation of the second driving device 23, the bending component 3 can bend the rear bending point 82 of the plate 8 while the cutting component 4 cuts the plate material 8.

[0027] The sheet metal cutting and bending device can cut two sheets of long sheet metal 8 in the same device, and bend the rear edge of the sheet metal separated from the long sheet metal 8. The cutting and bending of the rear edge of the sheet metal are performed simultaneously, which has high processing efficiency and solves the technical problem that existing sheet metal processing devices cannot perform cutting and bending of sheet metal 8 at the same time.

[0028] To further explain, the end face of the lower bending template 33 facing the lower bending blade 34 is tangent to the lower bending blade 34, and the end of the upper bending blade 35 is flush with the end face of the lower bending template 33 facing the lower bending blade 34.

[0029] This configuration allows the first upper bending blade 35 to press the sheet metal 8 as close as possible to the bending point. In other words, when the upper bending blade 35 presses the sheet metal 8 against the lower bending template 33, the end face of the upper bending blade 35 near the lower bending blade 34 is precisely in contact with the point where bending is required. The first lower bending blade 34 can then bend the sheet metal 8 upwards at the bending point, effectively ensuring the bending effect.

[0030] To further explain, the horizontal plane at which the lower end face of the bending upper blade 35 is located is higher than the horizontal plane at which the lower end face of the upper cutting blade 43 is located.

[0031] This configuration ensures that while the upper bending blade 35 and the lower bending template 33 are in close contact and pressing down on the sheet material 8, the upper cutting blade 43 can complete the cutting of the sheet material 8.

[0032] Furthermore, the bending assembly 3 also includes a pad 36 and a spring 37. The pad 36 is fixedly disposed on the bending die base plate 31, and the lower bending template 33 is fixedly disposed on the upper end face of the pad 36. The lower bending template 33 is located above the movable seat 32. The upper end of the spring 37 is fixedly connected to the bottom end face of the lower bending template 33, and the lower end of the spring 37 is fixedly connected to the upper end face of the movable seat 32.

[0033] The pad 36 is used to support the lower bending template 33. The spring 37 is located between the lower bending template 33 and the movable seat 32. When the second driving device 23 drives the movable seat 32 to move upward, the spring 37 is compressed. When the second driving device 23 drives the movable seat 32 to move downward, the movable seat 32 is assisted in resetting under the elastic action of the spring 37.

[0034] Preferably, multiple springs 37 are provided, and the multiple springs 37 are spaced apart along the length direction of the bending lower template 33, so that the multiple springs 37 can all assist the movable seat 32 in resetting along the length direction of the bending lower template 33.

[0035] Furthermore, the cutting assembly 4 also includes a support plate 44, which is fixedly disposed on the fixing plate 41 and located on the side of the lower cutter 42 away from the bending assembly 3. The upper end face of the support plate 44 is flush with the upper end face of the lower cutter 42.

[0036] By setting the pallet 44, the sheet material 8 can be supported on the pallet 44 when it is fed. The upper end face of the pallet 44 is flush with the upper end face of the lower cutter 42, so that the sheet material 8 can be placed flat during cutting. When the upper cutter 43 moves downward, the upper cutter 43 and the lower cutter 42 are tangent to the end face of the bending assembly 3, thereby realizing the cutting of the sheet material 8.

[0037] Specifically, the cutting end of the upper cutter 43 is a blade-shaped blade that slopes downward toward the lower cutter 42.

[0038] To further explain, the pallet 44 is provided with a guide slope 441, which is inclined downward in a direction away from the lower cutter 42.

[0039] By setting the guide slope 441, and the guide slope 441 is inclined downward in a direction away from the lower cutter 42, the sheet material 8 is fed from one side of the cutting assembly 4. The guide slope 441 can guide the sheet material 8 into the cutting assembly 4, so that the sheet material 8 can smoothly enter the sheet cutting and bending device for processing.

[0040] Furthermore, the sheet metal cutting and bending device also includes a synchronization component 6, which includes a guide post 61, a movable bushing 62, a synchronization shaft 63, a synchronization gear 64, and a synchronization rack 65. The guide post 61 is fixedly disposed on the mold frame assembly 1 in the vertical direction, and the guide post 61 is disposed on both sides of the movable plate 21 in the length direction. The movable bushing 62 is fixedly connected to both ends of the movable plate 21 in the length direction. The movable bushing 62 is slidably disposed on the corresponding guide post 61. The synchronous shaft 63 is horizontally disposed in the length direction of the movable plate 21. The synchronous shaft 63 is fixedly connected to the movable bushing 62, and the synchronous gear 64 is fixedly connected to both ends of the synchronous shaft 63. The synchronous rack 65 is fixedly disposed on the mold frame assembly 1, and the synchronous rack 65 is located on both sides of the length direction of the movable plate 21. The synchronous gear 64 meshes with the corresponding synchronous rack 65.

[0041] Because the movable plate 21 is relatively long, by setting the synchronization component 6, when the first driving device 22 drives the movable plate 21 to move downward, the two ends of the movable plate 21 can move downward synchronously under the action of the synchronization gear 64 and the synchronization rack 65 meshing. For example, when one end of the movable plate 21 moves downward in the length direction, it will drive the movable bushing 62 at that end to move downward. The downward movement of the movable bushing 62 will drive the synchronization shaft 63 to move downward. The synchronization gear 64 on the synchronization shaft 63 moves downward along the synchronization rack 65. Since the synchronous shaft 63 moves downward, it can also link the movable bushing 62 at the other end to move downward, thereby realizing the linkage movement of the movable plate 21 in the length direction. This avoids the situation where one end moves downward to the correct position while the other end does not, resulting in one end of the plate 8 being cut and bent while the other end is not.

[0042] In addition, the guide post 61 can also guide the movable plate 21.

[0043] Preferably, there are two first driving devices 22, which are spaced apart along the length of the movable plate 21. The two first driving devices 22 drive the movable plate 21 to move synchronously on both sides of the movable plate 21, thereby improving the synchronicity of the downward movement of both ends of the movable plate 21 in the length direction. Two second driving devices 23 are provided, and the two second driving devices 23 are spaced apart along the length direction of the movable seat 32. The two second driving devices 23 synchronously drive the movable seat 32 to move on both sides of the movable seat 32, so as to ensure the synchronicity of the movement of the two ends of the movable seat 32 in the length direction.

[0044] Preferably, the first drive device 22 and the second drive device 23 are hydraulic cylinders, which have the characteristics of strong load-bearing capacity and reliable operation.

[0045] To further explain, the mold frame assembly 1 includes a mold frame base plate 11, a mold frame side plate 12, and a mold frame top plate 13. The mold frame side plates 12 are fixedly disposed on both sides of the mold frame base plate 11 along its length, and the mold frame top plate 13 is fixedly disposed on the upper end surface of the mold frame side plates 12. The first driving device 22 is fixedly mounted on the top plate 13 of the mold frame, thereby fixing the first driving device 22 to the mold frame assembly 1; The fixing plate 41, the bending die base plate 31 and the second driving device 23 are respectively fixedly disposed on the die frame base plate 11, so that the fixing plate 41, the bending die base plate 31 and the second driving device 23 are respectively fixedly disposed on the die frame assembly 1; The synchronous rack 65 is fixedly disposed on the mold frame side plate 12, thereby realizing the fixed disposal of the synchronous rack 65 on the mold frame assembly 1; The guide post 61 is fixedly disposed between the mold base plate 11 and the mold top plate 13, thereby fixing the guide post 61 to the mold assembly 1.

[0046] Furthermore, the sheet metal cutting and bending device also includes a limiting component 7, which includes an adjusting seat 71, a proximity switch group 72, a first sensing plate 73, and a second sensing plate 74. The adjusting seat 71 is installed on the mold frame top plate 13. The adjusting seat 71 is arranged in the vertical direction. Two groups of proximity switches 72 are detachably installed on the adjusting seat 71. Each group of proximity switches 72 includes two proximity switches 721 arranged at intervals. The first sensing plate 73 is fixedly installed on the movable plate 21, and the second sensing plate 74 is fixedly installed on the movable seat 32. The first sensing plate 73 is correspondingly disposed with the proximity switch group 72 located on the upper part of the adjusting seat 71, and the first sensing plate 73 is used to sense the proximity switch 721 of the proximity switch group 72 located on the upper part of the adjusting seat 71; the second sensing plate 74 is correspondingly disposed with the proximity switch group 72 located on the lower part of the adjusting seat 71, and the second sensing plate 74 is used to sense the proximity switch 721 of the proximity switch group 72 located on the lower part of the adjusting seat 71.

[0047] Specifically, the proximity switch 721 can be used to control the upward and downward positions of the movable plate 21 and the movable seat 32. For example, when the first sensing plate 73 moves downward with the movable plate 21 to sense the proximity switch 721 below the corresponding proximity switch group 72, the first driving device 22 controls the movable plate 21 to stop moving, and the movable plate 21 moves into position; when the movable plate 21 moves upward to sense the proximity switch 721 above the corresponding proximity switch group 72, the first driving device 22 controls the movable plate 21 to stop moving, and the movable plate 21 completes its reset; the control of the movable seat 32 is similar. In this way, the moving positions of the movable plate 21 and the movable seat 32 can be controlled to ensure that the cutting and bending are in place and the reset is in place.

[0048] Specifically, the adjusting seat 71 is made of aluminum profile and has a through groove for mounting the proximity switch 721. The through groove is arranged in the vertical direction. The proximity switch 721 can be detachably mounted to the adjusting seat 71 by bolts, thereby realizing the adjustment of the position of the proximity switch 721 according to production needs, so as to adjust the moving position of the movable plate 21 and the movable seat 32.

[0049] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
