Description

Technical Field

[0001] This utility model relates to the field of steel sheet processing technology, and in particular to a shearing device for processing silicon steel sheets. Background Technology

[0002] A steel sheet shearing device is a mechanical device used to cut steel sheets or other metal plates. It is commonly used in industrial production, especially in metal processing, automobile manufacturing, and steel processing. Steel sheet shearing devices use strong mechanical pressure to cut metal plates into sheets of the required size, and are often used in mass production, material processing, and parts manufacturing.

[0003] In existing technologies, steel sheet shearing devices use a fixed cutting speed for shearing. This may prevent the shearing speed from being adjusted for steel sheets of different materials. Excessive shearing speed may cause cracks or other damage to the surface of the silicon steel sheet, resulting in unnecessary damage to the steel sheet surface and affecting product quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a shearing device for processing silicon steel sheets.

[0005] This utility model is achieved by the following technical solution: a shearing device for processing silicon steel sheets, comprising a shearing mechanism, a fixing mechanism and a conveying mechanism, wherein the shearing mechanism is located at the top of the conveying mechanism and the fixing mechanism is located at the top of the conveying mechanism;

[0006] The shearing mechanism includes a workbench, a support plate fixedly connected to the top of the workbench, a threaded rod rotatably connected inside the support plate, a handle fixedly connected to the top of the threaded rod, a connecting plate threadedly connected to the threaded rod, a motor fixedly connected to the top of the connecting plate, a gear fixedly connected to the output end of the motor, a gear meshing with the gear, a connecting rod fixedly connected inside the gear, a fixing block rotatably connected to the outer wall of the connecting rod, the fixing block fixedly connected to the top of the connecting plate, a turntable fixedly connected to the end of the connecting rod away from the gear, a threaded rod rotatably connected inside the turntable, a handle fixedly connected to the top of the threaded rod, a slider threadedly connected to the threaded rod, a fixing rod fixedly connected to the end of the slider away from the connecting rod, a connecting rod rotatably connected to the outer wall of the fixing rod, a fixing rod rotatably connected to the end of the connecting rod away from the fixing rod, and a cutter fixedly connected to the outer wall of the fixing rod.

[0007] Through the above technical solution, the motor drives the gears to rotate. Gears mesh with each other, and gear one drives the turntable to rotate via a connecting rod. The turntable, in turn, drives a fixed rod to rotate via the connecting rod. The fixed rod is fixed to the cutter. When cutting steel sheets of different materials, the operator rotates the threaded rod via the handle. The threaded rod is threadedly connected to the slider, changing the slider's position relative to the turntable's center point. The varying circumference of the slider's rotation around the turntable alters the cutter's vertical movement, thus changing the cutting speed. Different thicknesses, hardnesses, or types of silicon steel sheets may require different cutting speeds. Adjusting the speed ensures optimal cutting results on different materials, thereby improving production efficiency, reducing surface damage to the steel sheet, and improving product quality.

[0008] As a further improvement to the above solution, the fixing mechanism includes a fixing plate, which is fixedly connected to the top of the workbench. A pressure block is slidably connected to the inner wall of the fixing plate, and a fixing rod is fixedly connected to the top of the pressure block.

[0009] As a further improvement to the above solution, the second fixing rod is slidably connected inside the fixing plate, and a cylinder is fixedly connected to the end of the second fixing rod away from the pressure block. A first support plate is fixedly connected to the outer wall of the cylinder, and the first support plate is fixedly connected to the top of the fixing plate.

[0010] Through the above technical solution, the cylinder is fixed to the second fixing rod, which slides inside the fixing plate. At the same time, the second fixing rod is fixed to the pressure block, which fixes the steel sheet and prevents the steel sheet from shifting during the shearing process, thus improving the shearing accuracy and ensuring consistent product quality.

[0011] As a further improvement to the above solution, the conveying mechanism includes a motor, which is fixedly connected inside the workbench. A connecting rod is fixedly connected to the output end of the motor, and a wheel is fixedly connected to the outer wall of the connecting rod.

[0012] As a further improvement to the above scheme, a belt is rotatably connected to the outer wall of the wheel, a first wheel is rotatably connected to the outer wall of the belt, and a third connecting rod is rotatably connected inside the first wheel.

[0013] As a further improvement to the above solution, the connecting rod three is fixedly connected to the right side of the workbench, the inner wall of the belt is rotatably connected to the wheel three, and the connecting rod four is fixedly connected inside the wheel three.

[0014] As a further improvement to the above solution, a fixing block is rotatably connected to the outer wall of the connecting rod, the fixing block is fixedly connected to the top of the workbench, and a conveying wheel is fixedly connected to the outer wall of the connecting rod.

[0015] Through the above technical solution, motor one drives the rotating wheel to rotate via connecting rod two. The rotating wheel drives rotating wheel one and rotating wheel three to rotate simultaneously via belt. Rotating wheel one and connecting rod three rotate, while rotating wheel three drives the conveyor wheel to rotate via connecting rod four. The conveyor wheel contacts the steel sheet, thereby realizing automatic feeding. Motor one can accurately control the feeding speed and quantity, thereby ensuring consistent quality of each feeding, facilitating the cutting of steel sheets of different sizes, and improving the product qualification rate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a motor to drive gears, which mesh with each other. Gear 1 drives a turntable via a connecting rod, which in turn drives a fixed rod via the connecting rod. The fixed rod is fixed to the cutter. When cutting steel sheets of different materials, the operator rotates a threaded rod via a handle. This threaded rod is threaded onto a slider, changing the slider's position relative to the turntable's center. The slider's circumference around the turntable varies, altering the cutter's vertical movement and thus the cutting speed. Different thicknesses, hardnesses, or types of silicon steel sheets may require different cutting speeds. Adjusting the speed ensures optimal cutting results on different materials, thereby improving production efficiency, reducing surface damage to steel sheets, and enhancing product quality.

[0018] This invention uses a cylinder to fix the second fixing rod, which slides inside the fixing plate. At the same time, the second fixing rod is fixed to the pressure block, which fixes the steel sheet and prevents the steel sheet from shifting during the shearing process, thus improving the shearing accuracy and ensuring consistent product quality.

At the top of the connecting plate 105, a turntable 111 is fixedly connected to the end of the connecting rod 109 away from the gear 108. A threaded rod 112 is rotatably connected inside the turntable 111. A handle 113 is fixedly connected to the top of the threaded rod 112. A slider 114 is threadedly connected to the threaded rod 112. A fixing rod 115 is fixedly connected to the end of the slider 114 away from the connecting rod 109. A connecting rod 116 is rotatably connected to the outer wall of the fixing rod 115. A fixing rod 117 is rotatably connected to the end of the connecting rod 116 away from the fixing rod 115. A cutter 118 is fixedly connected to the outer wall of the fixing rod 117.

[0030] The fixing mechanism 2 includes a fixing plate 201, which is fixedly connected to the top of the workbench 101. A pressure block 202 is slidably connected to the inner wall of the fixing plate 201, and a fixing rod 203 is fixedly connected to the top of the pressure block 202.

[0031] The second fixing rod 203 is slidably connected inside the fixing plate 201. The end of the second fixing rod 203 away from the pressure block 202 is fixedly connected to the cylinder 204. The outer wall of the cylinder 204 is fixedly connected to the first support plate 205. The first support plate 205 is fixedly connected to the top of the fixing plate 201.

[0032] The conveying mechanism 3 includes a motor 301, which is fixedly connected inside the workbench 101. A connecting rod 302 is fixedly connected to the output end of the motor 301, and a wheel 303 is fixedly connected to the outer wall of the connecting rod 302.

[0033] A belt 304 is rotatably connected to the outer wall of the wheel 303, a wheel 305 is rotatably connected to the outer wall of the belt 304, and a connecting rod 306 is rotatably connected inside the wheel 305.

[0034] Connecting rod 306 is fixedly connected to the right side of workbench 101. The inner wall of belt 304 is rotatably connected to wheel 307, and connecting rod 408 is fixedly connected inside wheel 307.

[0035] The outer wall of the connecting rod 308 is rotatably connected to the fixing block 309, which is fixedly connected to the top of the workbench 101. The outer wall of the connecting rod 308 is fixedly connected to the conveying wheel 310.

[0036] The implementation principle of the shearing device for silicon steel sheet processing in this embodiment is as follows: The steel sheet is placed on the top of the workbench 101. Simultaneously, motor 301 drives the rotating wheel 303 to rotate via connecting rod 302. The rotating wheel 303, via belt 304, simultaneously drives rotating wheels 305 and 307 to rotate. Rotating wheel 305 rotates with connecting rod 306, while rotating wheel 307 rotates with connecting rod 308, driving the conveying wheel 310 to rotate. The conveying wheel 310 contacts the steel sheet, thus achieving automatic feeding. Motor 301 can precisely control the feeding speed and quantity, ensuring consistent quality for each feeding, facilitating the cutting of steel sheets of different sizes, and improving product qualification rate. When the sheet is conveyed to a certain position, cylinder 204 is fixed to fixing rod 203, causing fixing rod 203 to slide inside the fixing plate 201. Simultaneously, fixing rod 203 is fixed to pressure block 202, which secures the steel sheet and prevents it from slipping during shearing. During the cutting process, steel sheet displacement causes product defects, thereby improving cutting accuracy and ensuring consistent product quality. Motor 106 drives gear 107 to rotate, gear 107 meshes with gear 108, gear 108 drives turntable 111 to rotate via connecting rod 109, turntable 111 drives fixed rod 117 to rotate via connecting rod 116, and fixed rod 117 is fixed to cutter 118, thus completing the cutting. When cutting steel sheets of different materials, different cutting speeds are required. At this time, the operator rotates threaded rod 112 via handle 113. Threaded rod 112 is threadedly connected to slider 114, changing the position of slider 114 from the center point of turntable 111. This ensures that the circumference of slider 114 rotating around turntable 111 is different, thus changing the up and down movement distance of cutter 118, thereby changing the cutting speed. Different thicknesses, hardnesses, or types of silicon steel sheets may require different cutting speeds. Adjusting the speed ensures optimal cutting results on different materials, thereby improving production efficiency, reducing damage to the steel plate surface, and improving product quality. At the same time, when the vertical movement distance of the cutter 118 changes, the operator drives the threaded rod 103 to rotate through the handle 104. The threaded rod 103 is threadedly connected to the connecting plate 105, and the connecting plate 105 is fixed to the motor 106 to prevent the cutter 118 from directly colliding with the worktable 101, thus preventing tool damage and extending tool life.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
