Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, and in particular to a cutting device for steel structure processing. Background Technology

[0002] Various steel structures are frequently used in construction projects. Cutting devices are used to cut and process steel structures according to actual needs to obtain steel components of different sizes. Currently, most cutting devices mainly use saw blades for cutting. After cutting, burrs are inevitably generated at the cut points of the steel components. When workers handle the cut steel components, their hands are easily scratched by the burrs, which can affect their physical and mental health.

[0003] For example, there is a Chinese patent application with the number CN214417811U, which describes a cutting device for steel production: "It includes an operating table, a groove is opened along the length direction at the center of the top of the operating table, and a slider is slidably installed in the groove. A base plate is welded to the top outer wall of the slider, and a cutting motor is bolted to the top outer wall of the base plate. A cutting blade is bolted to the outer wall of one end of the output shaft of the cutting motor."

[0004] It is evident that the cited patent document has the problem of burrs at the cut edges that can easily scratch the hands of workers. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for steel structure processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for steel structure processing, comprising a workbench, a fixing mechanism for fixing steel components on the top surface of the workbench, a threaded shaft on the top surface of the workbench via an inverted U-shaped bracket, a movable block threaded around the circumference of the threaded shaft, a movable frame horizontally fixed on the bottom surface of the movable block, a bidirectional threaded rod rotatably connected to the inner walls of both sides of the movable frame, a moving block symmetrically threaded around the circumference of the bidirectional threaded rod, a hinge plate hinged to the bottom surface of each of the two moving blocks, a lifting plate hinged to the free end of each of the two hinge plates, the lifting plate being positioned directly below the movable frame, a drive motor fixedly mounted on the bottom surface of the lifting plate, and a grinding roller for deburring fixedly connected to the output shaft of the drive motor.

[0007] Preferably, the threaded shaft is positioned directly above the fixing mechanism, and the grinding roller is positioned on one side of the fixing mechanism.

[0008] Preferably, a cylinder is fixed to the inner side wall of the bracket, and the piston rod of the cylinder is fixed to an inverted U-shaped vertical block.

[0009] Preferably, the bottom surface of the vertical block is provided with a saw blade for cutting steel components via a rotating shaft, and a rotary motor is fixed to one side of the vertical block.

[0010] Preferably, one end of the output shaft and the rotating shaft of the rotary motor both extend to one side of the vertical block, and a belt connects the output shaft and the rotating shaft of the rotary motor.

[0011] Preferably, the top surface of the workbench is provided with a threaded rod via a vertical groove, and a bottom block is symmetrically threaded around the circumference of the threaded rod.

[0012] Preferably, both base blocks are arranged in an inclined U-shape, and the fixing mechanism includes a pressure block disposed in the inner cavity of the base block and a bolt rotatably connected to the top surface of the pressure block.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This cutting device for steel structure processing can remove burrs from the cut surface of steel components by setting a grinding roller, and the threaded shaft can drive the grinding roller to move along the cut surface to remove burrs.

[0015] By using a bidirectional threaded rod, a moving block, and a hinged plate, the grinding roller can be driven to move longitudinally. This allows for adjustment based on steel components of different thicknesses and those with irregular surfaces, reducing the risk of workers being scratched by burrs at the cut edges when handling the cut steel components and minimizing the impact on their physical and mental health.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 5 The cutting device shown includes a workbench 1 with legs mounted on its bottom surface to raise its height. A fixing mechanism for securing steel components is provided on the top surface of the workbench 1. A threaded rod 17 is rotatably mounted on the top surface of the workbench 1 via a vertical groove. Two base blocks 18 are symmetrically threaded around the threaded rod 17, both arranged in an inclined U-shape. The fixing mechanism includes a pressure block 19 disposed within the cavity of the base block 18 and a bolt rotatably connected to the top surface of the pressure block 19, the top end of the bolt penetrating to the bottom surface. The top surface of block 18 and the two ends of threaded rod 17 are machined with threads in opposite directions. By rotating threaded rod 17, the two bottom blocks 18 can be moved in opposite or relative directions to accommodate steel components of different sizes. After the steel component is placed on the top surface of the two bottom blocks 18, the bolt is rotated to move the pressure block 19 downward, so that the pressure block 19 and the bottom block 18 can clamp and fix the steel component, which is convenient for subsequent cutting. One side of the pressure block 19 is in frictional contact with the inner wall of the bottom block 18, which can restrict the position of the pressure block 19.

[0028] The top surface of the workbench 1 is provided with a threaded shaft 3 via an inverted U-shaped bracket 2. The threaded shaft 3 is positioned directly above the fixed mechanism. A movable block 4 is threaded around the periphery of the threaded shaft 3, so that when the threaded shaft 3 rotates, it can drive the movable block 4 to move. Limiting rods are fixed on the inner walls of both sides of the bracket 2 and directly above the threaded shaft 3. The movable block 4 is slidably sleeved around the periphery of the limiting rods, which can restrict the movement of the movable block 4.

[0029] A movable frame 5 is horizontally fixed to the bottom surface of the movable block 4. Two-way threaded rods 6 are rotatably connected to the inner walls of both sides of the movable frame 5. Moving blocks 7 are symmetrically threaded around the periphery of the two-way threaded rods 6. The bottom surfaces of the two moving blocks 7 are hinged to hinge plates 8. Lifting plates 9 are hinged to the free ends of the two hinge plates 8. The lifting plates 9 are located directly below the movable frame 5. When the two-way threaded rods 6 rotate, they will synchronously drive the two moving blocks 7 to move in opposite or relative directions, so that the two moving blocks 7 can drive the two hinge plates 8 to move. When the two moving blocks 7 move in opposite directions, they will drive the lifting plates 9 to move downward through the hinge plates 8. Conversely, when the two moving blocks 7 move in opposite directions, they will drive the lifting plates 9 to move upward through the hinge plates 8, so that the lifting plates 9 can perform longitudinal reciprocating motion below the movable frame 5.

[0030] A drive motor 10 is fixedly mounted on the bottom surface of the lifting plate 9. The output shaft of the drive motor 10 is fixedly connected to a grinding roller 11 for cleaning burrs. The grinding roller 11 is located on one side of the fixed mechanism. The drive motor 10 can drive the grinding roller 11 to rotate. In conjunction with the threaded shaft 3 driving the movable block 4 to move, the grinding roller 11 can enter the cutting area of ​​the steel structure and fit against the cutting area. With the drive motor 10 driving the grinding roller 11 to rotate, the burrs at the cutting area can be cleaned. The longitudinal reciprocating motion of the lifting plate 9 will drive the grinding roller 11 to perform longitudinal reciprocating motion, so that the grinding roller 11 can clean the cutting areas of thicker steel structures and irregular steel components, reducing the possibility of workers being scratched by burrs at the cutting area when handling the cut steel components, and reducing the impact on the physical and mental health of workers.

[0031] The threaded rod 17 enables the two bottom blocks 18 to move in opposite directions, thereby separating the steel structures cut into two, making it easier to move the grinding roller 11 between the two steel structures.

[0032] Motors are installed on one side of the bracket 2, the movable frame 5, and the worktable 1, respectively. The output shafts of the three motors pass through the bracket 2, the movable frame 5, and the worktable 1 and are fixedly connected to one end of the threaded shaft 3, the double-threaded rod 6, and the threaded rod 17, respectively, so as to provide power for the rotation of the threaded shaft 3, the double-threaded rod 6, and the threaded rod 17.

[0033] A cylinder 12 is fixedly mounted on the inner wall of the support 2. An inverted U-shaped vertical block 13 is fixedly mounted on the piston rod of the cylinder 12. A saw blade 14 for cutting steel components is rotatably mounted on the bottom surface of the vertical block 13 via a rotating shaft. The saw blade 14 is located on one side of the two bottom blocks 18. A rotary motor 15 is fixedly mounted on one side of the vertical block 13. The output shaft of the rotary motor 15 and one end of the rotating shaft both extend through one side of the vertical block 13. A belt 16 is connected between the output shaft of the rotary motor 15 and the rotating shaft. Pulleys are installed on the periphery of the output shaft of the rotary motor 15 and the periphery of the rotating shaft. The belt 16 is located on the periphery of the two pulleys, and one pulley is larger than the other. When it is necessary to cut the steel structure, the rotary motor 15 is turned on, so that the output shaft of the rotary motor 15 drives the saw blade 14 to rotate through the belt 16 and the rotating shaft. The cylinder 12 drives the saw blade 14 to move, so that the saw blade 14 cuts the steel structure.

[0034] Working principle:

[0035] This cutting device for steel structure processing places the steel component to be cut on the top surface of two base blocks 18 and clamps and fixes it with bolts and pressure blocks 19. Then, the rotary motor 15 is turned on, causing the saw blade 14 to rotate via the belt 16 and the shaft. Simultaneously, the cylinder 12 is activated, causing the saw blade 14 to move and cut the steel component. After cutting, the cylinder 12 returns the saw blade 14 to its original position. Then, by rotating the threaded rod 17 via the motor, the two base blocks 18 move in opposite directions, allowing the two cut steel components to move together. The distance is sufficient for the grinding roller 11 to pass through. At this time, the motor connected to the threaded shaft 3 is turned on, which allows the threaded shaft 3 to rotate and drive the movable block 4 to move. The movable block 4 can then drive the grinding roller 11 to move between the two steel components and press against the cut edges of the two steel components. At this time, the drive motor 10 is turned on, which drives the grinding roller 11 to rotate and, together with the threaded shaft 3, drives the grinding roller 11 to move. This allows the grinding roller 11 to clean the burrs at the cut edges of the steel components, reducing the risk of workers being scratched by burrs when handling the cut steel components and minimizing the impact on the physical and mental health of the workers.
