[0002] The greatest success of containers lies in the standardization of their products and the entire transportation system established as a result, which can standardize a huge product with a load capacity of dozens of tons, and gradually realize a logistics system that matches ships, ports, routes, roads, transfer stations, bridges, tunnels, and multimodal transport on a global scale. Container doors are usually connected to the container through hinges, and the round steel on the hinges usually needs to be cut off by a round steel cutting machine during the processing process.

[0003] The existing round bar cutting machine, when in use, uses a hydraulic cylinder to drive an upper cutter to cut the round steel. However, the upper cutter frequently contacts the end face of the round steel, which causes friction, resulting in wear on the opposite sides of the upper and lower cutters, thereby reducing the round steel cutting accuracy and shortening the life of the upper and lower cutters of the cutting machine. In addition, the rear end face of the round steel is relatively sharp after cutting, and workers may cut their hands during the centralized collection process. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4In the embodiment of the utility model, the automatic round steel cutting device for processing container door hinges includes an operating table 1, a conveying mechanism 2 is arranged on the top surface of the operating table 1, a profile frame 11 is fixedly connected to one end of the top surface of the operating table 1, a lower cutter 12 is fixedly connected to the top surface of the operating table 1 and located inside the profile frame 11, hydraulic cylinders 13 are fixedly connected to both ends of the inner top surface of the profile frame 11, a connecting plate 14 is fixedly connected to the output ends of the two hydraulic cylinders 13, an upper cutter 15 is fixedly connected to the bottom surface of the connecting plate 14, an oiling mechanism 3 is arranged on the top surface of the profile frame 11, and an oiling mechanism 3 is arranged on the top surface of the operating table 1 and located inside the profile frame 11. A grinding mechanism 4 is provided on one side, and the oiling mechanism 3 includes a stabilizing plate 31 fixed between two opposite sides of the mold frame 11, and a sponge 32 in contact with the upper cutter 15 is fixedly connected to one side of the stabilizing plate 31, and a sleeve 33 is fixedly connected to the top surface of the mold frame 11, and a piston is slidably connected inside the sleeve 33, and an oil outlet pipe 34 plugged into the sponge 32 is fixedly penetrated and fixed on the inner bottom surface of the sleeve 33, and an oil storage tank 35 is fixedly connected to one end of the top surface of the mold frame 11, and an oil inlet pipe 36 is fixedly connected between the interior of the oil storage tank 35 and the interior of the sleeve 33, and a one-way valve is fixed inside the oil inlet pipe 36 and the oil outlet pipe 34.

[0022] Specifically, firstly, the long round steel is placed on the conveying mechanism 2, and the long round steel is conveyed by the conveying mechanism 2. When one end of the round steel moves between the upper cutter 15 and the lower cutter 12, the conveying mechanism 2 is closed, and then the two hydraulic cylinders 13 are started to enable the connecting plate 14 to drive the upper cutter 15 and the lower cutter 12 to move until the upper cutter 15 cuts the round steel. Since the upper cutter 15 will generate friction with the cross-section lower cutter 12 of the round steel during the process of cutting the round steel, when the two hydraulic cylinders 13 drive the connecting plate 14 and the upper cutter 15 to move upward, the piston is moved downward in the sleeve 33, so that the lubricating oil in the sleeve 33 can flow into the sponge 32 through the oil outlet pipe 34. Since the upper cutter 15 is in contact with the sponge 32, the sponge 32 that has absorbed the lubricating oil can apply a part of the lubricating oil to the upper cutter 15. The upper cutter 15 is on the knife 15, so the friction between the upper cutter 15 and the cross section of the round steel and the lower cutter 12 can be reduced, thereby improving the accuracy of round steel cutting, and improving the service life of the upper cutter 15 and the lower cutter 12. When the upper cutter 15 moves down again, the piston moves up in the sleeve 33 at this time. Since the inside of the oil inlet pipe 36 and the oil outlet pipe 34 are fixed with a one-way valve, the upward movement of the piston can draw the lubricating oil in the oil storage tank 35 into the sleeve 33, and the downward movement of the piston can press the lubricating oil in the sleeve 33 into the sponge 32. Since the rear end surface of the round steel is relatively sharp when it is cut, in order to prevent the staff from being cut by the cross section of the round steel when holding the cut round steel by hand, in order to prevent the staff from being cut by the cross section of the round steel, when the conveying mechanism 2 conveys the round steel to between the upper cutter 15 and the lower cutter 12, the cross section of the round steel can be polished by the polishing mechanism 4.

[0024] like Figure 2-3 As shown, in this embodiment, the top surface of the mold frame 11 is fixedly connected to two symmetrical support plates 16, the top surface of the piston is fixedly connected to a push rod that slides through the top surface of the sleeve 33, the top of the push rod is fixedly connected to a rack 37, a gear 38 meshing with the rack 37 is rotatably connected between the two support plates 16, the top surface of the connecting plate 14 is fixedly connected to a vertical plate 39 that slides through the top surface of the mold frame 11, and the top of the vertical plate 39 is fixedly connected to a rack 391 that meshes with the gear 38.

[0025] In this embodiment, the upward movement of the two hydraulic cylinders 13 can drive the vertical plate 39 and the rack 2 391 to move upward, and the upward moving rack 2 391 can cause the gear 1 38 to rotate. Since the gear 1 38 is meshed with the rack 1 37, the rotating gear 1 38 can cause the rack 1 37 to move downward, and the downward moving rack 1 37 can cause the push rod to drive the piston to move downward in the sleeve 33, so that the lubricating oil in the sleeve 33 can be pressed into the sponge 32. Conversely, the downward movement of the upper cutter 15 can cause the piston to move upward in the sleeve 33, so that the lubricating oil in the oil storage tank 35 can be drawn into the sleeve 33.

[0026] Embodiment 2

[0027] like Figure 2 and Figure 4 As shown, in this embodiment, the grinding mechanism 4 includes a rectangular sleeve 41 slidably connected to the top surface of the operating table 1, the inner sliding sleeve of the rectangular sleeve 41 is connected to a telescopic plate 42, and the bottom surface of the telescopic plate 42 is fixedly connected to multiple springs 421 fixed to the inner bottom surface of the rectangular sleeve 41 at equal intervals, and the telescopic plate 42 is rotatably connected to a cylindrical tube 43 on the side opposite to the mold frame 11, and the inner sliding sleeve of the cylindrical tube 43 is connected to a cylindrical block 44, and one end of the cylindrical block 44 is provided with a jack of a conical structure, and sandpaper is detachably connected to the jack, and a spring 441 is fixedly connected between the cylindrical block 44 and the cylindrical tube 43, and one end of the top surface of the operating table 1 is fixedly connected to a baffle 17, and one end of the top surface of the operating table 1 is provided with two pairs of Two symmetrical electric push rods 47 are fixedly connected between the slide groove 18, the baffle plate 17 and the rectangular sleeve 41, the bottom surface of the rectangular sleeve 41 is fixedly connected with a slider 411 slidably connected to the slide groove 18 at the corresponding position, the outer wall of the cylindrical tube 43 is fixedly connected with a gear ring 431, one side of the telescopic plate 42 is rotatably connected with a rotating shaft, the outer wall of the rotating shaft is fixedly connected with a gear 2 45 meshing with the gear ring 431, one side of the telescopic plate 42 is fixedly connected with a motor 46, the output end of the motor 46 passes through the telescopic plate 42 and is fixedly connected to the rotating shaft, a plurality of limit grooves are provided in annular shapes at equal angles on the inner wall of the cylindrical tube 43, and the outer wall of the cylindrical block 44 is fixed with two limit blocks slidably connected to the limit grooves at corresponding positions.

[0028] In this embodiment, when the conveying mechanism 2 conveys the round steel to between the upper cutter 15 and the lower cutter 12, the two electric push rods 47 drive the rectangular sleeve 41 to drive the telescopic plate 42 and the cylindrical block 44 to move toward the mold frame 11 until the end of the round steel is inserted into the jack, and then the motor 46 is started to drive the gear 2 45 to drive the gear ring 431 to rotate, so that the cylindrical barrel 43 can rotate. Since the cylindrical block 44 is under the action of the limit block and the limit groove at the corresponding position, the rotation of the cylindrical barrel 43 can cause the cylindrical block 44 to rotate. Since sandpaper is provided in the socket and the socket is a conical structure, the rotating cylindrical block 44 can grind the edge of the cross section of the round rod with sandpaper, thereby preventing the staff from cutting their hands at the edge of the cross section of the round steel when manually taking the cut round rod. Since the upper cutter 15 is pressing down to cut the round steel, part of the round steel inserted into the socket will also move downward, so the part of the round steel that moves downward will drive the telescopic plate 42 to be retracted into the rectangular sleeve 41. When the round steel is cut and slides out of the socket, the telescopic plate 42 returns to its original position under the action of multiple springs 421.
