DETAILED DESCRIPTION

[0029] The following will be combined with the attached embodiment of the present utility model Figure 1-12 , the technical solutions in the embodiments of the utility model are described in detail.

[0030] like Figure 1 As shown, a metal sheet shearing device includes a mounting frame 1 for fixing a shearing component 3, a workbench 2 for supporting, a shearing component 3 for shearing sheets, a clamping device 4 for clamping sheets of different thicknesses, a tensioning component 5 for tensioning, a conveying device 6 for conveying sheets of different thicknesses, and a clamping component 7 for clamping and fixing sheets of different thicknesses. The mounting frame 1 is vertically fixed to the workbench 2 by screws, the shearing component 3 is arranged inside the mounting frame 1 along the length direction of the mounting frame 1, and the shearing component 3 is fixedly connected to the top plate of the mounting frame 1, so that the metal sheet input into the mounting frame 1 by the clamping device 4 is cut by the shearing component 3, the clamping device 4 is located on one side of the mounting frame 1 and is rotatably connected to the workbench 2 along the width direction of the workbench 2, so that the metal sheet clamped and fixed by the clamping device 4 will be fed into the interior of the mounting frame 1 under the action of the clamping device 4.

[0031] like Figure 1As shown, the metal sheet will then be sheared through the shearing component 3. The tensioning component 5 is located at one end of the clamping device 4 and the tensioning component 5 is fixedly connected to the workbench 2. When the clamping component adjusts its position up and down according to the thickness of the plate, the tensioning component 5 can correctly tension the first chain 46 inside the clamping device 4 to avoid the first chain 46 being too loose, thereby causing the clamping device 4 to slip. The conveying device 6 is located on the side of the clamping device 4 close to the clamping device 4 and one end of the conveying device 6 is connected to the workbench 2. Therefore, after the metal sheet is placed on the conveying device 6, it can be conveyed into the interior of the clamping device 4 through the conveying device 6. The clamping component 7 has two groups located on both sides of the conveying device 6 and slidably connected to the conveying device 6. Therefore, when working, the clamping device can clamp the metal sheet according to the width of the metal sheet so that it can be correctly fed into the interior of the clamping device 4. The gear box 8 is located at one end of the clamping device 4 and is vertically fixedly connected to the workbench 2. The clamping device 4 is rotatably connected to the workbench 2 through the gear box 8.

[0032] like Figure 2-3 As shown, the shearing assembly 3 includes a cylinder 31, a tool holder 32, a tool seat 33, a fixing bolt 34 and a shearing blade 35. The cylinder 31 is vertically arranged inside the mounting frame 1, and the cylinder 31 is fixedly connected to the center position of the top plate of the mounting frame 1 by screws. The tool holder 32 is arranged at the bottom end of the cylinder 31 according to the length direction of the mounting frame 1, and the tool holder 32 is fixedly connected to the output end of the cylinder 31 by screws. Therefore, under the action of the cylinder 31, the tool holder 32 can move up and down. The tool seat 33 is also arranged inside the mounting frame 1 according to the length direction of the mounting frame 1, and the tool holder 33 is located below the tool holder 32 and is slidably connected to the inside of the tool holder 32. Therefore, when the tool holder 33 needs to be replaced, it only needs to slide the tool holder 33 horizontally to remove the tool holder 33 from the tool holder 32. There are two groups of fixing bolts 34 and they are respectively arranged at both ends of the tool holder 32. The end parts of the two groups of fixing bolts 34 pass through the tool holder 33 and are threadedly connected to the inside of the tool holder 33.

[0033] like Figure 2-3As shown, after the knife seat 33 is placed in the interior of the knife holder 32, the knife seat 33 can be fixed to the interior of the knife holder 32 by the fixing bolts 34 to prevent the knife seat 33 from falling off the knife holder 32 when the cylinder 31 drives the shear blade 35 to cut the plate. At the same time, when the knife seat 33 needs to be replaced, it is only necessary to remove the fixing bolts 34 from the knife holder 32 to replace the knife seat 33. The shear blade 35 is arranged in the interior of the knife seat 33 according to the length direction of the knife seat 33, and the shear blade 35 is fixedly connected to the interior of the knife seat 33 by screws. Therefore, when the shear blade 35 needs to be replaced after the shear blade 35 collapses, it is only necessary to replace the knife seat 33, and the knife seat 33 will drive the shear blade 35 to be replaced together. At the same time, when the shear blade 35 is needed to cut the plate, it is only necessary for the cylinder 31 to drive the knife holder 32 to move up and down. When the knife holder 32 moves up and down, the shear blade 35 can be driven by the knife seat 33 to move up and down to cut the plate.

[0034] like Figure 4-5 As shown, the gear box 8 includes a box body 81, a rotating shaft 82, a main gear 83, a sub gear 84 and a driven wheel 85. The box body 81 is located at one end of the active roller 41 and is vertically fixedly connected to the workbench 2 by screws. The rotating shaft 82 is rotatably connected to the inside of the box body 81 through a bearing seat rotating shaft 82. The main gear 83 is sleeved on the rotating shaft 82 and is fixedly connected to the rotating shaft 82 by a clamp block. Therefore, when the main gear 83 rotates, the main gear 83 will drive the rotating shaft 82 to rotate together. The sub gear 84 is located on one side of the main gear 83 and is also fixedly connected by a clamp block. On the rotating shaft 82, therefore, when the main gear 83 drives the rotating shaft 82 to rotate, the rotating shaft 82 will synchronously drive the sub-gear 84 to rotate, and the driven wheel 85 is located below the sub-gear 84 and is fixedly connected to the rotating shaft of the active roller 41 of the clamping device 4 through a clamping block, and the sub-gear 84 and the driven wheel 85 are meshed with each other, so when the sub-gear 84 is driven to rotate by the rotating shaft 82, the sub-gear 84 will synchronously drive the driven wheel 85 to rotate, and the rotation directions of the sub-gear 84 and the driven wheel 85 are opposite, and the first chain 46 of the clamping device 4 is sleeved on the main gear 83.

[0035] like Figure 4-5As shown, the clamping device 4 includes an active roller 41, a first motor 42, a hydraulic cylinder 43, a driven roller 44, a first gear 45 and a first chain 46. The active roller 41 is arranged on one side of the mounting frame 1 according to the width direction of the workbench 2, and the active roller 41 is rotatably connected to the workbench 2. The first motor 42 is located on one side of the active roller 41 and is arranged on the outside of the workbench 2. The first motor 42 is fixedly connected to the workbench 2 by screws, and the output end of the first motor 42 passes through the workbench 2 and is plugged into the rotating shaft of the active roller 41. Therefore, the first motor 42 will drive the active roller 41 to rotate when it is started. There are two groups of hydraulic cylinders 43, both of which are vertically arranged on the workbench 2. The two groups of hydraulic cylinders 43 are fixedly connected to the workbench 2 by screws, and the two groups of hydraulic cylinders 43 are respectively arranged at the two ends of the active roller 41. The driven roller 44 is located above the active roller 41, and the two ends of the rotating shaft of the driven roller 44 are respectively rotatably connected to the output ends of the two groups of hydraulic cylinders 43.

[0036] like Figure 4-5 As shown, when in use, the distance between the driven roller 44 and the active roller 41 can be adjusted up and down by two groups of hydraulic cylinders 43 according to the thickness of the metal plate, so that when shearing the plate, the active roller 41 and the driven roller 44 can correctly press the plate. The first gear 45 is located above the gear box 8 and is fixedly connected to the rotating shaft of the driven roller 44 through a block. Therefore, when the first gear 45 rotates, the first gear 45 will synchronously drive the driven roller 44 to rotate. The first chain 46 is sleeved on the first gear 45, the main gear 83 and the tensioning wheel 54 of the tensioning assembly 5. Therefore, when the first motor 42 is started, the first motor 42 will drive the active roller 41 to rotate.

[0037] like Figure 4-5 As shown, when the active roller 41 rotates, it will drive the driven wheel 85 to rotate. When the driven wheel 85 rotates, it will drive the sub-gear 84 and the main gear 83 to rotate. The first chain 46 is mounted on the first gear 45 and the main gear 83. Therefore, when the sub-gear 84 rotates, the sub-gear 84 will drive the first gear 45 to rotate through the main gear 83 and the first chain 46. Therefore, the rotation direction of the sub-gear 84 is opposite to that of the driven wheel 85, and the rotation direction of the main gear 83 and the first gear 45 is the same as that of the sub-gear 84. Therefore, the rotation direction of the driven wheel 85 is opposite to that of the first gear 45, that is, the options of the active roller 41 and the driven roller 44 are opposite.

[0038] like Figure 6-7As shown, the tensioning assembly 5 includes a fixed seat 51, a hinge 52, a torsion spring 53 and a tensioning wheel 54. The fixed seat 51 is located on one side of the active roller 41 and is welded on the workbench 2. The hinge 52 is vertically arranged on one side of the fixed seat 51 and the rotating shaft at one end of the hinge 52 is rotatably connected to the inside of the fixed seat 51, so that the hinge 52 can rotate with the rotating shaft as the center of the circle. The torsion spring 53 is horizontally arranged inside the fixed seat 51 and sleeved on the rotating shaft of the hinge 52. On, one end of the torsion spring 53 is inserted into the inner wall of the fixed seat 51, and the other end of the torsion spring 53 is inserted into the rotating shaft of the hinge 52. The tensioning wheel 54 is located above the fixed seat 51 and is rotatably connected to the other end of the hinge 52, and the first chain 46 is sleeved on the tensioning wheel 54. Therefore, when the first gear 45 rotates, the first gear 45 will drive the tensioning wheel 54 to rotate synchronously through the first chain 46, and the rotation direction of the tensioning wheel 54 is the same as that of the first gear 45.

[0039] like Figure 6-7 As shown, when the hydraulic cylinder 43 lifts the driven roller 44 upward and the distance between the driven roller 44 and the active roller 41 increases, the hinge 52 starts to rotate forwardly around the rotating shaft at one end of the hinge 52 under the drive of the tension wheel 54. At this time, the tension wheel 54 starts to move laterally toward the axial position of the first gear 45. When the rotating shaft at one end of the hinge 52 rotates, it drives one end of the torsion spring 53 to start rotating synchronously, and the other end of the torsion spring 53 is inserted into the fixed seat 51. When the hinge 52 rotates, the torsion spring 53 will begin to deform and accumulate force, and when the hydraulic cylinder 43 adjusts the height of the driven roller 44 downward and the distance between the driven roller 44 and the active roller 41 decreases, the torsion spring 53 will use the force accumulated during deformation to drive the hinge 52 to reset. At this time, the tensioning wheel 54 will drive the first chain 46 to move toward the workbench 2 to ensure that the first chain 46 can be properly tensioned to prevent the first chain 46 from being too loose and causing the active roller 41 and the driven roller 44 to slip.

[0040] like Figure 8-9As shown, the conveying device 6 includes a base 61, a driven conveying roller 62, an active conveying roller 63, a second motor 64, a second gear 65, a third gear 66, a second chain 67, a fourth gear 68 and a third chain 69. There are multiple groups of driven conveying rollers 62 and they are evenly arranged inside the base 61 according to the length direction of the base 61, and all the driven conveying rollers 62 are rotatably connected inside the base 61. The active conveying roller 63 is arranged inside the base 61 and located at one end of the base 61, and the active conveying roller 63 is also rotatably connected inside the base 61. The second motor 64 is located at one end of the active conveying roller 63 and is arranged below the active conveying roller 63, and the second motor 64 is fixedly connected to the base 61 by screws. The second gear 65 is plugged into the output end of the second motor 64 by a card block. Therefore, when the second motor 64 is working, the second motor 64 will synchronously drive the second gear 65 to rotate. The third gear 66 is located above the second gear 65 and is also plugged into the rotating shaft of the active conveying roller 63 by a card block.

[0041] like Figure 8-9 As shown, when the third gear 66 rotates, the third gear 66 will synchronously drive the active conveying roller 63 to rotate, and the second chain 67 is sleeved on the second gear 65 and the third gear 66. Therefore, when the motor is started, the second gear 65 will drive the third gear 66 to rotate synchronously through the second chain 67, and the second gear 65 and the third gear 66 have the same rotation direction. The other end of the rotating shaft of the active conveying roller 63 is plugged with a fourth gear 68 by a block, and the rotating shaft of the driven conveying roller 62 and the same end of the rotating shaft of the active conveying roller 63 are also connected. The fourth gear 68 is inserted with a card block, and the third chain 69 is sleeved on the fourth gear 68 of the driven conveying roller 62 and the active conveying roller 63. Therefore, when the third gear 66 drives the active conveying roller 63 to rotate, the active conveying roller 63 will drive all the driven conveying rollers 62 to rotate through the fourth gear 68 and the third chain 69, and all the driven conveying rollers 62 have the same rotation direction as the active conveying roller 63. Slots are provided at both ends of the base 61, and the two groups of electric slides 74 of the clamping assembly 7 are respectively arranged in the slots at both ends of the base 61.

[0042] like Figure 10-12As shown, the clamping assembly 7 includes a first baffle 71, a second baffle 72, a clamping wheel 73 and an electric slide 74, the first baffle 71 is located above the base 61 and is arranged on one side of the base 61 according to the length direction of the base 61, and the first baffle 71 is fixedly connected to the base 61 by screws, the second baffle 72 is located on the other side of the base 61 and is slidably connected to the base 61, and the inner walls of the first baffle 71 and the second baffle 72 are vertically provided with a plurality of groups of The clamping wheel 73 is provided with a plurality of clamping wheels, and each group of clamping wheels 73 is fixedly connected to the first baffle plate 71 and the second baffle plate 72 by screws. Therefore, when the second baffle plate 72 slides laterally, the clamping wheel 73 will be driven to move synchronously. There are two groups of electric slides 74, which are respectively located in the slide grooves at both ends of the base 61. The two groups of electric slides 74 are fixedly connected to the inside of the base 61, and the two ends of the second baffle plate 72 are respectively fixedly connected to the sliders of the two groups of electric slides 74, so that when the electric slide 74 is started, the second baffle plate 72 will be driven to move laterally.

[0043] The movement process of this embodiment is as follows: first, the distance between the active roller 41 and the driven roller 44 is adjusted by the hydraulic cylinder 43 according to the thickness of the metal plate to be cut, and then the hydraulic cylinder 43 is started, so that the hydraulic cylinder 43 can drive the driven roller 44 to rotate synchronously through the driven wheel 85, the auxiliary gear 84 and the main gear 83 inside the gear box 8. When the hydraulic cylinder 43 adjusts the distance between the active roller 41 and the driven roller 44, the tensioning assembly 5 will always tension the first chain 46 to prevent the first chain 46 from being too loose, thereby causing the active roller 4 1 and the driven roller 44 slip, and then the second motor 64 is started to drive the driven conveying roller 62 to rotate synchronously through the active conveying roller 63, and then the distance between the first baffle plate 71 and the second baffle plate 72 is adjusted according to the width of the metal sheet to be cut and the electric slide 74 is used to adjust the distance between the first baffle plate 71 and the second baffle plate 72 so that the metal sheet can be clamped correctly, and then the metal sheet can be placed on the driven conveying roller 62, and after the driven conveying roller 62 drives the metal sheet to the position of the shearing assembly 3, the cylinder 31 can be used to drive the shear blade 35 to move up and down to cut the sheet.
