Steel structure cutting refers to the process of cutting and processing steel structures according to needs in industrial production.

[0003] In the use of existing technology, workers place the steel structure on the platform of the cutting device and cut the steel structure by pressing down the cutting wheel, making the steel structure convenient for subsequent use.

[0004] However, in actual use, it is difficult to ensure that the cutting angle is completely consistent every time when the cutting machine is operated manually, which affects the quality of subsequent welding and requires frequent disassembly and assembly, thus affecting processing efficiency.

[0012] This utility model provides an adjustable-angle steel structure cutting device. It offers the following advantages: Through the cooperation of a rotating plate, bolts, and friction pads, this adjustable-angle steel structure cutting device allows the rotating plate to rotate during steel structure cutting, adjusting the cutting angle of the cutter.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In actual use, it is difficult to ensure that the cutting angle is completely consistent every time when the cutting machine is operated manually, which affects the quality of subsequent butt welding and requires frequent disassembly and assembly, thus affecting processing efficiency.

[0018] In view of this, the present invention provides an adjustable angle steel structure cutting device, which solves the problem that in actual use, it is difficult to ensure that the cutting angle is completely consistent every time when the cutting machine is operated manually, which affects the quality of subsequent butt welding and requires frequent disassembly and assembly, thus affecting processing efficiency.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Example 1: By Figure 1-4It is known that the adjustable angle steel structure cutting device includes a base 1, a cutter 2 is installed on the top of the base 1, an installation rod 8 is installed on the top of the cutter 2, a handle 10 is installed on the top of the installation rod 8, a rotating plate 3 is installed at the bottom of the installation rod 8, the bottom of the rotating plate 3 is rotatably connected to the top of the base 1 through a sealed bearing, a bolt 20 is threadedly connected to the inner wall of the rotating plate 3, a friction pad 13 is pressed against the end of the bolt 20 extending to the bottom of the rotating plate 3, the bottom of the friction pad 13 is fixedly connected to the top of the base 1, a slider 19 is fixedly connected to the bottom of the rotating plate 3 on one side of the bolt 20, the outer wall of the slider 19 is slidably engaged with the inner wall of the base 1, and a drive device is installed on the outer wall of the cutter 2. In the specific implementation process, it is worth noting that the installation rod 8 is used to support the cutter 2 to ensure that the cutter 2 is stable when cutting the steel structure. The cutter 2 is driven to cut the steel structure by pressing down the handle 10. A bearing is set at the bottom of the rotating plate 3 so that the rotating plate 3 drives the cutter 2 to rotate, and the cutting angle of the cutter to the steel structure can be adjusted. The friction pad 13 is made of rubber with a pattern on its surface, thereby increasing the friction between the bolt 20 and the friction pad 13. The rotating plate 3 is fixed to the top of the base 1, and with the cooperation of the slider 19, the rotating plate 3 is stable when rotating and will not jam. Furthermore, the drive device includes a support frame 6, the outer wall of the support frame 6 is movably connected to the outer wall of the cutter 2, a servo motor 7 is fixedly connected to one end of the cutter 2 extending to the outer wall of the support frame 6, the outer wall of the servo motor 7 is fixedly connected to the outer wall of the support frame 6, the top of the support frame 6 is fixedly connected to the bottom of the mounting rod 8, and a protective shell 5 is provided on the outer wall of the cutter 2, the outer wall of the protective shell 5 is fixedly connected to the outer wall of the mounting rod 8. In the specific implementation process, it is worth noting that the outer wall of the support frame 6 is rotatably connected to the outer wall of the cutter 2 through the bearing, and the cutter 2 is driven by the servo motor 7 to make the cutter 2 rotate rapidly to cut the steel structure. The protective shell 5 set in front of the cutter 2 will block the impurities generated when the cutter 2 comes into contact with the steel structure, and prevent the splashed debris from affecting the workers. Furthermore, the top of the mounting rod 8 is rotatably connected to the support rod 17 via a pin, the top of the support rod 17 is rotatably connected to the handle 10 via a pin, the end of the handle 10 is fixedly connected to the connecting shaft 9, and the bottom of the connecting shaft 9 is movably connected to the top of the mounting rod 8. In the specific implementation process, it is worth noting that when the handle 10 is pressed, the support rod 17 is squeezed against the mounting rod 8. When the support rod 17 squeezes against the mounting rod 8, the mounting rod 8 will drive the cutter 2 to move downward. The connecting shaft 9 can make the handle 10 rotate around it. Through the lever action, the support rod 17 squeezes against the mounting rod 8, causing the cutter 2 to move downward to cut the workpiece.

[0021] Example 2: From Figure 1-4 It can be seen that the top of the rotating plate 3 is fixedly connected to the mounting post 11, the top of the mounting post 11 is fixedly connected to the limiting post 18, the outer wall of the limiting post 18 is inserted into the inner wall of the mounting rod 8, the end of the limiting post 18 extending to the top of the mounting rod 8 is fixedly connected to the bottom of the connecting shaft 9, and the outer wall of the limiting post 18 is sleeved with a spring 12, which abuts against the mounting post 11 and the mounting rod 8. In the specific implementation process, it is worth noting that the outer wall of the limiting post 18 is provided with a protrusion, which allows the mounting rod 8 to slide stably on its outer wall without shaking. In addition, the elastic force of the spring 12 is greater than the weight of the parts installed on the mounting rod 8, ensuring that the mounting rod 8 can be raised to its original position. When the operator presses the handle 10, he rotates around the part where the handle 10 is connected to the connecting shaft 9, so that the support rod 17 squeezes the mounting rod 8, causing the mounting rod 8 to drive the cutter 2 to move on the outer wall of the limiting post 18 and squeeze the spring 12. After cutting, after releasing the handle 10, the mounting rod 8 drives the cutter 2 back to its original position under the support of the elastic force of the spring 12. This avoids the problem of the operator not being able to lift it to the correct position after use, which could easily cause danger. It is also worth noting that a counterweight is installed on the side of the mounting rod 8 away from the cutter 2 to ensure the stability of the mounting rod 8 when it moves downward, and to prevent the inner wall of the mounting rod 8 from getting stuck between the outer wall of the limiting post 18. Furthermore, a limiting frame 14 is fixedly connected to the top front side of the base 1, a fixing frame 15 is fixedly connected to the top of the limiting frame 14, a pressure plate 16 is provided below the fixing frame 15, a magnet 21 is embedded in the bottom of the pressure plate 16, and a screw 22 is rotatably connected to the top of the pressure plate 16 through a bearing. The upper part of the outer wall of the screw 22 is connected to the inner wall of the fixing frame 15 through a thread. In the specific implementation process, it is worth noting that the position of the steel structure is limited by the limiting frame 14, and the pressure plate 16 is pressed against the steel structure by rotating the screw 22. The inner wall of the fixing frame 15 is provided with the same thread as the outer wall of the screw 22. When the screw 22 is rotated, the pressure plate 16 is pressed against the top of the steel structure, and under the attraction of the magnet 21, the pressure plate 16 moves stably towards the steel structure. This prevents the screw 22 from rotating along with the pressure plate 16 due to the friction between the screw 22 and the pressure plate 16, ensuring that the pressure plate 16 is fixed and stable to the steel structure. When cutting the steel structure, the cutting angle of the cutter 2 is adjusted first, and then the steel structure is placed on the limiting frame 14 and aligned directly below the cutter 2 to ensure that the cutter 2 is stable when cutting the steel structure. It is worth noting that the limiting frame 14 is relatively long, which allows the steel structure to be cut at different angles of the cutter 2. Furthermore, a limit rod 4 is provided below the cutter 2, and the outer wall of the limit rod 4 is fixedly connected to the outer wall of the rotating plate 3; In the specific implementation process, it is worth noting that there are two limit rods 4, which are located on both sides of the end of the rotating plate 3 respectively. After the cutter 2 finishes cutting the steel structure, it can prevent the cutter 2 from damaging the top of the base 1, ensuring that the cutter 2 and the base 1 will not be damaged.
