[0035] See also Figure 1-7 The present invention provides a technical solution: a sheet metal comprehensive experimental table, including an experimental table body 1, and two drawers 2 are slidably connected to one side of the experimental table body 1 to provide a storage space for the replaced structure.

[0036] The surface of the experimental bench body 1 is provided with a punching, shearing and buckling mechanism 3, which includes a mounting frame 301. The surface of the mounting frame 301 is fixedly connected to the surface of the experimental bench body 1. A first mounting plate 306 is provided at the bottom of the mounting frame 301. A buckling plate 303 is provided at the bottom of the first mounting plate 306 to buckle the material. A second mounting plate 304 is fixedly connected to one side of the first mounting plate 306.

[0037] A third mounting plate 309 is fixedly connected to one side of the second mounting plate 304 away from the first mounting plate 306 . The first mounting plate 306 , the second mounting plate 304 and the third mounting plate 309 are arranged in a stepped shape. A shearing knife 307 is arranged at the bottom of the third mounting plate 309 for cutting materials.

[0038] A mounting groove 302 is provided on the surface of the experimental table body 1, and three mounting frames 312 are slidably connected to the inner wall of the mounting groove 302. The three mounting frames 312 correspond to the first mounting plate 306, the second mounting plate 304 and the third mounting plate 309 respectively. The three mounting frames 312 are respectively provided with buckle frames 311, punching plates 314 and shear plates 315, which correspond to the buckle plates 303, punches 310 and shear knives 307 respectively, so that the device can smoothly perform corresponding processing on the materials.

[0039] Furthermore, the inner walls of the three mounting frames 312 are fixedly connected with four connecting rods 316, and the surfaces of the connecting rods 316 slide with the inside of the buckle plate 303, the punch 310 and the shear knife 307. Then, through the setting of the connecting rods 316, the connection between the buckle plate 303, the punch 310 and the shear knife 307 and the mounting frame 312 can be achieved more quickly, thereby reducing the difficulty of using the device and making it more suitable for students.

[0040] The bottom of the three mounting frames 312 are all rotatably connected with a lifting screw 317, the surface of the lifting screw 317 is connected to the internal thread of the laboratory bench body 1, the surface of the laboratory bench body 1 is rotatably connected with a first operating rod 313, and the first operating rod 313 is located at one end inside the laboratory bench body 1 and is fixedly connected to a first bevel gear 319, the interior of the laboratory bench body 1 is rotatably connected with a second bevel gear 318, the surface of the first bevel gear 319 is meshed with the surface of the second bevel gear 318, the surface of the lifting screw 317 is slidably connected with the interior of the second bevel gear 318, and the lifting screw 317 and the second bevel gear 318 are connected by a spline, so that when the second bevel gear 318 rotates, it can smoothly push the lifting screw 317 to rotate, and at the same time does not affect the mutual sliding between the lifting screw 317 and the second bevel gear 318, thereby ensuring the smooth operation of the device.

[0041] Furthermore, a cylinder 4 is fixedly connected to the top of the mounting frame 301, and the output end of the cylinder 4 passes through the surface of the mounting frame 301 and is slidably connected to the inside of the mounting frame 301, providing power for the punching, shearing and buckling mechanism 3 to operate, ensuring that the device has sufficient power to punch, shear and buckle the material, thereby ensuring the use effect of the device.

Thus, by providing the reinforcing plate 308, the connection strength between the first mounting plate 306 and the second mounting plate 304 and between the second mounting plate 304 and the third mounting plate 309 is strengthened, thereby preventing the cylinder 4 from driving the second mounting plate 304 to descend, causing the first mounting plate 306 and the third mounting plate 309 to be affected by the strength of the material when processing the material, resulting in the first mounting plate 306 and the third mounting plate 309 being broken from the second mounting plate 304, thereby ensuring the strength of the device structure and ensuring the smooth processing of the material by the device.

[0043] The surface of the first mounting plate 306 is threadedly connected with a connecting screw 305, and the surface of the third mounting plate 309 is also provided with a connecting screw 305, and the number of connecting screws 305 on the third mounting plate 309 is four, and the lower end of the connecting screw 305 is also connected to the internal thread of the buckle plate 303 and the shear knife 307, so that the user can disassemble and assemble the buckle plate 303 and the shear knife 307 by rotating the connecting screw 305, thereby facilitating the user to replace the buckle plate 303 and the shear knife 307, so that students can process materials of different sizes, which improves the versatility of the device and is worthy of promotion. At the same time, the arrangement of the four connecting screws 305 on the third mounting plate 309 enables the shear knife 307 to be installed longitudinally and transversely, so that the device can cut the material longitudinally and transversely, further improving the scope of application of the device.

[0044] Furthermore, a bending mechanism 5 is provided on the surface of the experimental bench body 1, and the bending mechanism 5 includes a rotating disk 501, and the surface of the rotating disk 501 is rotatably connected to the inside of the experimental bench body 1, and a fixing rod 503 is fixedly connected to the inside of the experimental bench body 1, and the surface of the fixing rod 503 is rotatably connected to the inside of the rotating disk 501, and a through groove 507 is opened at the upper end of the fixing rod 503 to provide a placement space for the material to be bent, and clamping plates 504 are slidably connected to both sides of the inner wall of the through groove 507, and the opposite sides of the two clamping plates 504 are rotatably connected to adjust screws 505, and the surface of the adjusting screw 505 is connected to the internal thread of the fixing rod 503, and then through the setting of the adjusting screw 505, the user can adjust the distance between the two clamping plates 504 by rotating the adjusting screw 505, so that the device can clamp and fix materials of different thicknesses, thereby further improving the scope of application of the device, and then being able to better satisfy the curiosity of students, bend any material, and further improve the use effect of the device.

[0045] A fixed shaft 506 is fixedly connected to the surface of the rotating disk 501 , and can be used in conjunction with the fixed rod 503 to bend the material.

[0046] Furthermore, the surface of the laboratory bench body 1 is rotatably connected to a second operating rod 502 protruding from the surface of the laboratory bench body 1, and one end of the second operating rod 502 located inside the laboratory bench body 1 is fixedly connected to a worm 509, and the bottom of the rotating disk 501 is fixedly connected to a worm wheel 508, and the surface of the worm 509 is meshingly connected to the surface of the worm wheel 508.

[0047] Specifically, when bending the material, the user places the material in the through groove 507, and clamps the material with the clamping plate 504, and then rotates the second operating rod 502, thereby driving the rotating disk 501 to rotate, and then driving the fixed shaft 506 to squeeze and push one end of the protruding through groove 507, thereby bending the material. Secondly, a scale can be set on the experimental table body 1, that is, around the rotating disk 501, so as to facilitate the user to have a specific understanding of the bending angle of the material, making the use of the device clearer.

[0048] Secondly, when punching, shearing or buckling the material, the user operates the corresponding first operating rod 313, thereby driving the mounting frame 312 to rise to a certain height so that the structures on the remaining mounting plates will not contact the corresponding mounting frame 312, and then place the material on the corresponding mounting frame 312, and then start the cylinder 4 to drive all the mounting plates to descend and process the material, and then by arranging a punching, shearing and buckling mechanism 3 and a bending mechanism 5 on the experimental table body 1, punching, bending, buckling and shearing can be performed on the experimental table, so that students do not need to move back and forth, saving teaching time. At the same time, it reduces the area occupied by various equipment settings, thereby reducing the space occupied by sheet metal internships, making it more suitable for use in schools and worthy of promotion.

[0049] Working principle: When bending the material, the user places the material in the through slot 507, and clamps the material with the clamping plate 504, and then rotates the second operating rod 502, thereby driving the rotating disk 501 to rotate, and then driving the fixed shaft 506 to squeeze and push one end of the protruding through slot 507, thereby bending the material. When punching, shearing or buckling the material, the user operates the corresponding first operating rod 313, thereby driving the mounting frame 312 to rise to a certain height, so that the structures on the remaining mounting plates will not contact the corresponding mounting frame 312, and then place the material on the corresponding mounting frame 312, and then start the cylinder 4 to drive all the mounting plates to descend and process the material.
