And according to different requirements, the steel structure is processed. In one of the processing procedures, a cutting device is needed for processing. However, most of the current cutting devices do not have a structure for protecting the debris or metal melt generated during cutting, resulting in the debris or metal melt generated during cutting splashing everywhere. It is not only easy to splash everywhere on the workbench, but also splashes to the ground, making it difficult to clean up the splashed debris and metal melt, thus increasing the workload of the staff.

However, it will be apparent to those skilled in the art that the present utility model can be practiced without one or more of these details. In other instances, to avoid obscuring the present utility model, some well-known technical features are not described.

[0024] Unless otherwise defined, the up, down, left, right, front, back, inner, and outer directions referred to herein are based on the up, down, left, right, front, back, inner, and outer directions shown in the figures of the present utility model, and are hereby stated together for clarification.

[0025] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0026] As Figures 1 to 4 shown, a cutting device for steel structure processing includes a workbench 1. Support legs are fixedly provided on the bottom surface of the workbench 1. An electric push rod 2 is fixedly provided on one side of the top surface of the workbench 1 through a bracket. The bracket is arranged in an inverted L shape, and the electric push rod 2 is fixedly provided on the inner top surface of the bracket, so that the electric push rod 2 is directly above the workbench 1. A connecting rod 3 is longitudinally fixedly provided at the output end of the electric push rod 2. The bottom end of the connecting rod 3 is connected to a cutting disc 10 for cutting steel structures through a pin shaft. A motor is fixedly provided on one side surface of the connecting rod 3, and the output shaft of the motor penetrates through the connecting rod 3 and is connected to the pin shaft, so that the electric push rod 2 can drive the cutting disc 10 to move downward through the connecting rod 3, making the cutting disc 10 contact the steel structure. At this time, the motor is turned on, and the motor drives the cutting disc 10 to rotate to cut the steel structure.

[0027] A fixing plate 4 is fixedly arranged on the circumferential side of the connecting rod 3. Through holes 5 are respectively arranged through the top surface of the fixing plate 4 and on both sides of the connecting rod 3. Vertical rods 6 are slidably arranged in the inner cavities of the two through holes 5. The tops of the two vertical rods 6 respectively pass through the through holes 5 and are fixedly provided with limiting discs 7. The diameters of the two limiting discs 7 are both larger than the diameters of the two through holes 5. The bottoms of the two vertical rods 6 are connected with a protective cover 8 for restricting debris. The protective cover 8 is arranged below the connecting rod 3 and below the cutting disc 10. A through groove 9 for the cutting disc 10 to pass through is formed in the top surface of the protective cover 8. The size of the through groove 9 is larger than the size of the cutting disc 10. When the electric push rod 2 drives the connecting rod 3 to move downward, the fixing plate 4 will be driven to move downward synchronously. Due to gravity, the two vertical rods 6 will move downward synchronously, and then the two vertical rods 6 will drive the protective cover 8 to move downward. Since the protective cover 8 is arranged below the cutting disc 10, the protective cover 8 will contact the steel structure prior to the cutting disc 10. After the protective cover 8 abuts against the steel structure, continue to move the connecting rod 3 and the fixing plate 4. Since the protective cover 8 abuts against the steel structure, the protective cover 8 and the two vertical rods 6 will not move downward due to gravity. Then the fixing plate 4 can move downward on the circumferential sides of the two vertical rods 6 through the two through holes 5, thereby driving the cutting disc 10 to move downward and pass through the through groove 9, so that the cutting disc 10 enters the inner cavity of the protective cover 8. After the cutting disc 10 enters the inner cavity of the protective cover 8 and continues to move downward, the cutting disc 10 can abut against the steel structure. At this time, start the motor to drive the cutting disc 10 to rotate and cut the steel structure. The protective cover 8 will protect the cutting disc 10, and thus restrict the debris generated during cutting, reduce the problem that the debris is difficult to clean up due to splashing everywhere on the surface of the workbench 1, and reduce the workload of the staff during work.

[0028] After cutting is completed, the electric push rod 2 drives the connecting rod 3 and the fixing plate 4 to move upward. First, the cutting disc 10 can be driven to move upward, and then pass through the through groove 9 and be taken out from the inner cavity of the protective cover 8, and make the top surface of the fixing plate 4 abut against the bottom surface of the limiting disc 7. At this time, continue to move the connecting rod 3 and the fixing plate 4 upward, and the fixing plate 4 can drive the protective cover 8 to move upward through the limiting disc 7 and the vertical rod 6.

[0029] A movable plate 11 is slidably sleeved on the peripheral side of the connecting rod 3 and located between the fixed plate 4 and the cutting disc 10. The size of the movable plate 11 is larger than that of the through groove 9. A plurality of springs 12 are equidistantly connected to the top surface of the movable plate 11. The free end of each spring 12 is connected to the bottom surface of the fixed plate 4. The height of the protective cover 8 is greater than the diameter of the cutting disc 10 and the distance from the bottommost surface of the cutting disc 10 to the movable plate 11. Therefore, when the cutting disc 10 enters the inner cavity of the protective cover 8 and does not contact the steel structure, the movable plate 11 will abut against the top surface of the protective cover 8. At this time, if the connecting rod 3 and the fixed plate 4 are moved downward continuously, the fixed plate 4 can squeeze the springs 12, and the resilience of the springs 12 will push the movable plate 11, enabling the movable plate 11 to tightly abut against the top surface of the protective cover 8, so that the movable plate 11 can limit the through groove 9, and thus prevent debris from flying out of the through groove 9.

[0030] On the top surface of the workbench 1 and symmetrically fixed on one side of the bracket are fixed blocks 13. Both fixed blocks 13 are L-shaped, and the steel structure to be cut can be placed on the inner bottom surfaces of the two fixed blocks 13.

[0031] On the top surfaces of the two fixed blocks 13 are fixedly provided connecting frames 14. Longitudinal grooves 15 are opened on the opposite side surfaces of the two connecting frames 14. The inner bottom surfaces of the two grooves 15 are rotatably connected with threaded shafts 16. The tops of the two threaded shafts 16 penetrate above the connecting frames 14 and are fixedly provided with turning handles. Threaded sleeves in the shape of L are sleeved on the peripheral sides of the two threaded shafts 16. The ends of the two movable frames 17 far from the threaded shafts 16 are horizontally fixedly provided with pressing plates 18 for fixing the steel structure. After the steel structure is placed on the inner bottom surfaces of the two fixed blocks 13, the operator turns the turning handle to drive the threaded shaft 16 to rotate, so that the threaded shaft 16 can drive the movable frame 17 to move downward, thereby enabling the movable frame 17 to drive the pressing plate 18 to move downward, so that the pressing plate 18 can abut against the top surface of the steel structure. At this time, if it is moved downward continuously, the pressing plate 18 can squeeze the steel structure, thus achieving the effect of pressing and fixing, which is convenient for subsequent cutting.

[0032] On the inner bottom surface of the groove 15 and longitudinally fixed on one side of the threaded shaft 16 is a limiting rod 19, and the movable frames 17 are slidably sleeved on the peripheral sides of the limiting rods 19, which can limit the movement of the movable frames 17.

[0033] Working principle:

[0034] For the cutting device used for steel structure processing, place the steel structure to be cut on the top surfaces of two fixed blocks 13, and rotate the turning handle. Then, the movable frame 17 and the pressing plate 18 can be driven to move downward by the threaded shaft 16, so that the pressing plate 18 presses and fixes the steel structure. At this time, turn on the electric push rod 2. The electric push rod 2 drives the connecting rod 3 to move downward, and then synchronously drives the fixed plate 4 to move downward. Due to the gravity relationship, the two vertical rods 6 move downward synchronously, so that the protective cover 8 first abuts against the surface of the steel structure. At this time, continue to move the connecting rod 3 and the fixed plate 4, so that the fixed plate 4 can move downward along the circumference of the vertical rod 6 through the through hole 5, so that the cutting disc 10 passes through the through groove 9 and enters the inner cavity of the protective cover 8. Just after the cutting disc 10 enters the inner cavity of the protective cover 8, the bottom surface of the movable plate 11 abuts against the top surface of the protective cover 8. Continue to move the connecting rod 3 and the fixed plate 4 downward, and the fixed plate 4 can press the spring 12, so that when the movable plate 11 is at the top surface of the protective cover 8, the cutting disc 10 can continue to move downward. When the cutting disc 10 abuts against the steel structure, turn on the motor, and the motor drives the cutting disc 10 to rotate to cut the steel component. The protective cover 8 can limit the debris generated during cutting, reduce the problem that the debris is difficult to clean up when splashing everywhere on the workbench 1 surface, and reduce the workload of the staff during work.
