Description

Technical Field

[0001] This application relates to the field of cutting machines, and more particularly to a steel structure cutting device. Background Technology

[0002] A cutting machine is a widely used processing equipment in the industrial field, mainly used for dividing metal or non-metal materials. With the development of modern machining industry, the requirements for cutting quality and precision are constantly increasing, as are the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions. The development of CNC cutting machines must adapt to the requirements of modern machining industry. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, water jet cutting machines, etc. Laser cutting machines are the most efficient, have the highest cutting precision, and generally cut thinner materials. Plasma cutting machines also have a fast cutting speed and a certain bevel on the cut surface. Flame cutting machines are suitable for thicker carbon steel materials. Cutting machines are often used for processing steel structures. When processing steel structures with a conventional cutting machine, after the base is installed stably, the cutting machine body is installed on the top of the base. One end of the cutting machine body is rotatably connected to the cutting disc. After the workpiece is placed on the top of the base, the cutting disc is rotated and cut into a suitable shape by the control of the cutting machine body.

[0003] Regarding the aforementioned technologies, the inventors believe that when conventional cutting machines process steel structures, the high-speed rotation of the cutting disc in contact with the steel structure easily generates a lot of sparks, and the debris generated during cutting is easily thrown out. The high-temperature sparks and debris can easily cause injury to people and objects in the vicinity, thus creating certain safety hazards when using the cutting machine.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

A handle is fixedly connected to the top of the shielding box, and a receiving cloth is snapped into the inner wall of the shielding box. A limit rod is fixedly installed at one end of the receiving cloth. The shielding box has an "L" shaped cross-section. The receiving cloth is made of fire-resistant fiber cloth, and the dimensions of the surface of the receiving cloth are compatible with the dimensions of the inner wall of the shielding box.

[0010] Preferably, an anti-slip sheet is fixedly connected to one end of the mounting frame and the limiting frame that are close to each other. The anti-slip sheet is a rubber sheet, and the size and specifications of the surface of the anti-slip sheet are adapted to the size and specifications of the surface of the mounting frame. One end of the anti-slip sheet is snapped into the surface of the receiving cloth.

[0011] Preferably, the surface of the connecting rod is slidably installed on the inner wall of the base, and the dimensions of the connecting rod surface are adapted to the dimensions of the inner wall of the base. The two connecting rods are symmetrically distributed about the shielding box.

[0012] Preferably, the base has a threaded connection with a fixing bolt, one end of which is engaged with the surface of the connecting rod, and the fixing bolt and the connecting rod are perpendicular to each other.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a steel structure cutting device, referring to... Figure 1 - Figure 2The system includes a base 1. When processing steel structures, after the base 1 is installed and stabilized, a cutting machine body 2 is installed on the top of the base 1. A cutting disc 3 is rotatably connected to one end of the cutting machine body 2. After the workpiece is placed on the top of the base 1, the cutting disc 3 is rotated and cut into a suitable shape by means of the cutting machine body 2. A shielding box 5 is installed on one end of the base 1 by means of a connecting rod 4. A receiving cloth 6 is installed on the inner wall of the shielding box 5, and a handle 7 is installed on the top of the shielding box 5. The handle 7 allows for easy control of the movement of the shielding box 5. The shielding box 5 shields the sparks and debris generated when the cutting disc 3 is cutting. The receiving cloth 6 made of fire-resistant fiber material prevents sparks and impurities from rebounding after contacting the shielding box 5, which could cause injury to the user. This effectively improves the safety of steel structure cutting.

[0024] Reference Figure 2 A limiting rod 8 is installed at one end of the receiving cloth 6. The surface of the limiting rod 8 is engaged with the surface of the shielding box 5. A fixing rod 9 is installed on the inner wall of the shielding box 5. The surface of the fixing rod 9 is connected to the surface of the receiving cloth 6. The position of the receiving cloth 6 is restricted by the limiting rod 8 and the fixing rod 9, connecting the receiving cloth 6 to the shielding box 5, thereby ensuring the shielding effect of sparks and debris. A mounting bracket 10 is connected to the surface of the connecting rod 4. A limiting bracket 11 is rotatably connected to the surface of the mounting bracket 10. Two springs 12 are installed at the bottom of the limiting bracket 11. The bottom of the springs 12 is connected to the inner wall of the mounting bracket 10. The springs 12 push the limiting bracket 11 to keep the limiting bracket 11 connected to the surface of the receiving cloth 6, thereby ensuring the fixing effect of the receiving cloth 6. Rubber anti-slip plates 13 are installed on the surfaces of the mounting bracket 10 and the limiting bracket 11. The rubber material of the anti-slip plates 13 has the property of increasing friction, thereby improving the fixing efficiency of the mounting bracket 10 and the limiting bracket 11 on the receiving cloth 6.

[0025] Reference Figure 3 - Figure 4 A connecting rod 4 is installed at one end of the shielding box 5. The surface of the connecting rod 4 is slidably connected to the inner wall of the base 1. The connecting rod 4 facilitates the adjustment of the position of the shielding box 5, thereby avoiding obstruction when cutting materials of different sizes. A fixing bolt 14 is threadedly connected to the surface of the base 1. One end of the fixing bolt 14 is engaged with the surface of the connecting rod 4. The length of the connecting rod 4 is fixed by the fixing bolt 14, thereby improving the stability of the shielding box 5. Several connecting blocks 15 are installed on the surface of the shielding box 5. A pulley 16 is rotatably connected to the inner wall of the connecting block 15. The bottom end of the pulley 16 is slidably connected to the ground. The pulley 16 reduces the friction between the shielding box 5 and the ground, making it more convenient to move the shielding box 5.

[0026] The implementation principle of the steel structure cutting device in this application embodiment is as follows: A shielding box 5 is installed at one end of the base 1 via a connecting rod 4. A receiving cloth 6 is installed on the inner wall of the shielding box 5, and a handle 7 is installed on the top of the shielding box 5. The handle 7 allows for convenient control of the shielding box 5's movement, thus shielding the sparks and debris generated during cutting by the cutting disc 3. The receiving cloth 6, made of refractory fiber material, prevents sparks and impurities from rebounding after contact with the shielding box 5, thus avoiding injury to the user. A limiting rod 8 is installed at one end of the receiving cloth 6, and the surface of the limiting rod 8 engages with the surface of the shielding box 5. A fixing rod 9 is installed on the inner wall of the shielding box 5, and the surface of the fixing rod 9 connects with the surface of the receiving cloth 6, allowing the limiting rod 8 and the fixing rod to engage. 9 restricts the position of the receiving cloth 6 and connects the receiving cloth 6 to the shielding box 5 to ensure the shielding effect of sparks and debris. The surface of the connecting rod 4 is connected to the mounting bracket 10. The surface of the mounting bracket 10 is rotatably connected to the limiting bracket 11. Two springs 12 are installed at the bottom of the limiting bracket 11. The bottom of the springs 12 is connected to the inner wall of the mounting bracket 10 so that the limiting bracket 11 can be pushed by the springs 12 to keep the limiting bracket 11 connected to the surface of the receiving cloth 6, thereby ensuring the fixing effect of the receiving cloth 6. Rubber anti-slip plates 13 are installed on the surfaces of the mounting bracket 10 and the limiting bracket 11 so that the rubber material of the anti-slip plates 13 has the property of increasing friction, thereby improving the fixing effect of the mounting bracket 10 and the limiting bracket 11 on the receiving cloth 6.

[0027] The connecting rod 4 can also be installed at one end of the shielding box 5. The surface of the connecting rod 4 is slidably connected to the inner wall of the base 1, so that the position of the shielding box 5 can be easily adjusted with the help of the connecting rod 4. This avoids the shielding box 5 from obstructing the cutting of materials of different sizes. The surface of the base 1 is threaded with a fixing bolt 14. One end of the fixing bolt 14 is engaged with the surface of the connecting rod 4, so that the length of the connecting rod 4 can be fixed with the fixing bolt 14, thereby improving the stability of the shielding box 5. Several connecting blocks 15 are installed on the surface of the shielding box 5. The inner wall of the connecting block 15 is rotatably connected with a pulley 16. The bottom end of the pulley 16 is slidably connected to the ground, so that the friction between the shielding box 5 and the ground can be reduced with the help of the pulley 16, making it more convenient to move the shielding box 5.

[0028] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
