Technical Field

[0001] This application relates to the field of metal cutting technology, and in particular to a CNC flame cutting machine with improved safety. Background Technology

[0002] A CNC flame cutting machine is a machine tool driven by a digital program, equipped with a flame cutting system, and uses a CNC system to control the switching of the flame cutting system to cut metal materials such as steel plates; this type of mechatronic cutting equipment is called a CNC flame cutting machine.

[0003] Existing CNC flame cutting machines cut metal parts by igniting a mixture of gas and oxygen to generate a high-temperature flame after the operating program is set on the CNC console.

[0004] Regarding the aforementioned technologies, the inventors believe that during the cutting operation of the CNC flame cutting machine, the phenomenon of sparks and molten metal slag splashing inevitably occurs when the high-temperature flame comes into contact with the metal parts. This not only poses a direct threat to the working environment, equipment, and personnel, but may also cause serious safety hazards such as fires, resulting in low equipment safety. Utility Model Content

[0005] The purpose of this application is to provide a CNC flame cutting machine with improved safety, in order to address the problem of low safety in CNC flame cutting machines.

[0006] The CNC flame cutting machine with improved safety provided in this application adopts the following technical solution:

[0007] A CNC flame cutting machine with improved safety includes a machine body with a gantry frame. A CNC table and a drive unit are respectively located at both ends of the gantry frame. The machine body is characterized by: a CNC nozzle positioned between the CNC table and the drive unit; a cutting platform for placing metal parts positioned below the gantry frame; a cutting torch at the output end of the CNC nozzle; a baffle plate at the end of the cutting torch near the CNC nozzle; and several extended baffles on the baffle plate; the ends of the extended baffles away from the baffle plate are inclined downwards.

[0009] Optionally, the bottom of both ends of the gantry frame is provided with a sliding frame, and the machine tool body is provided with a slide rail for the sliding frame to slide along the length of the machine tool body.

[0010] By adopting the above technical solution, a sliding frame structure is added to the bottom of the gantry, enabling it to slide smoothly back and forth along the slide rails on the machine tool body. This flexible sliding method allows for precise adjustment of the gantry's position on the machine tool body according to actual needs, effectively improving its ease of use and flexibility.

[0011] Optionally, the blocking plate is rotatably connected to the extension baffle, and a positioning block is provided below the blocking plate to abut against the extension baffle.

[0012] By adopting the above technical solution and setting positioning blocks to limit the tilt angle of the extension baffle, the extension baffle can prevent sparks and molten metal slag from splashing while not affecting the normal operation of the cutting torch.

[0013] Optionally, the extended baffle is provided with a number of ventilation holes.

[0014] By adopting the above technical solution, small-diameter ventilation holes are opened on the extension baffle, so that the cutting torch can still fully contact oxygen while blocking sparks, thus maintaining the normal operation of the CNC flame cutting machine.

[0015] Optionally, a flame arrestor pad is provided on the side of the extended baffle near the cutting torch corresponding to the ventilation hole.

[0016] By adopting the above technical solution, a fire-arresting pad is installed on the extension baffle. The fire-arresting pad has holes corresponding to the ventilation holes, which reduces the impact of sparks on the extension baffle and increases the service life of the extension baffle.

[0017] Optionally, the cutting platform is provided with several guide plates and guide ramps.

[0018] By adopting the above technical solution, the molten metal slag produced by the CNC flame cutting machine after cutting metal parts can fall more dispersedly from the cutting platform, reducing the impact of the molten metal slag on the CNC flame cutting machine.

[0019] Optionally, a plurality of receiving plates are inserted into the cutting platform; the receiving plates are located below the guide plate and the guide ramp.

[0020] By adopting the above technical solution, the inserted receiving plate collects the falling molten metal slag, thus improving the environmental pollution caused by molten metal slag.

[0021] Optionally, the receiving plate is provided with a receiving baffle.

[0022] By adopting the above technical solution, the problem of molten metal slag sliding off the receiving plate when being pulled out of the CNC flame cutting machine, causing pollution to the working environment, can be improved by setting a receiving baffle.

[0023] Optionally, the receiving baffle is provided with a handle at one end near the edge of the cutting platform to facilitate the sliding of the receiving baffle.

[0024] By adopting the above technical solution and setting a handle, the insertion and sliding of the receiving plate in the CNC flame cutting machine can be facilitated, thereby improving work efficiency.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By adding a baffle plate and extending the baffle plate on the flame cutting torch, the spread range of sparks and molten metal slag splashes can be effectively controlled, thereby improving the problem of sparks or molten metal slag splashing onto the operator or equipment surface during the cutting process and improving the safety of CNC flame cutting machines;

[0027] 2. By setting positioning blocks, the tilt angle of the extension baffle is limited, so that the extension baffle can prevent sparks and molten metal slag from splashing while not affecting the normal operation of the cutting torch;

[0028] 3. The inserted receiving plate collects the falling molten metal slag. The receiving baffle prevents the molten metal slag from sliding off the receiving plate when it is pulled out of the CNC flame cutting machine, thus reducing the pollution of the environment by the molten metal slag.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0035] A CNC flame cutting machine with improved safety, as described in reference Figure 1 The machine tool body 1 is horizontal, and a gantry 3 is slidably mounted on the machine tool body 1. The gantry 3 is long and narrow. Sliding frames 31 are fixedly mounted at the bottom of both ends of the gantry 3 by welding. The machine tool body 1 is fixedly mounted with a slide rail 32 for the sliding frames 31 to slide along the length of the machine tool body 1 by welding.

[0036] Reference Figure 1 The gantry 3 has a CNC table 11 and a drive unit 12 installed at both ends. In this embodiment, the drive unit 12 is a motor. The CNC table 11, the drive unit 12 and the CNC nozzle 13 are electrically connected. The CNC nozzle 13 is installed on the crossbeam of the gantry 3 between the CNC table 11 and the drive unit 12. The machine tool body 1 is located below the gantry 3 and is fixedly installed with a cutting platform 2 for placing metal parts during processing by welding. The cutting platform 2 is in the shape of a horizontal hollow boss.

[0037] Reference Figure 1 and Figure 2 The cutting platform 2 is fixedly provided with a number of long strip-shaped guide plates 21 by welding along the length direction of the gantry frame 3. In this embodiment, the guide plates 21 are preferably 4. The cutting platform 2 is provided with a number of long strip-shaped guide inclined plates 22 by welding along the length direction of the machine tool body 1. In this embodiment, the inclination of the guide inclined plates 22 is preferably 5 degrees, and the number is preferably 8.

[0038] Reference Figure 2 The guide plate 21 is provided with an inclined groove for the guide sloping plate 22 to be inserted, and the guide sloping plate 22 is provided with a matching groove that fits into the inclined groove, so that the fit between the guide plate 21 and the guide sloping plate 22 is more stable; the design of the guide plate 21 and the guide baffle interlocking makes the metal parts more stably placed on the cutting platform 2.

[0039] Reference Figure 1 and Figure 3 The output end of the CNC nozzle 13 is connected to a cutting torch 4. A baffle plate 41 is fixedly fitted onto the end of the cutting torch 4 near the CNC nozzle 13 by welding. The baffle plate 41 is square plate-shaped. Several extension baffles 42 are provided on the baffle plate 41 by hinge rotation. The extension baffles 42 are square plate-shaped. In this embodiment, the number of extension baffles 42 is preferably 4. The end of the extension baffle 42 away from the baffle plate 41 is inclined downward.

[0040] Reference Figure 3A positioning block 43 is installed below the baffle plate 41 to abut against the extension baffle 42. The positioning block 43 is in the shape of a long strip. The tilt angle between the extension baffle 42 and the cutting torch 4 in the length direction can be adjusted by changing the type of positioning block 43. In this embodiment, the tilt angle is preferably 30 degrees.

[0041] Reference Figure 3 The extended baffle 42 is provided with a number of ventilation holes 44. Under the premise of ensuring sufficient oxygen supply, it effectively blocks the sparks and molten metal slag splashes generated by the CNC flame cutting machine during the cutting process through scientific hole diameter parameters, while maintaining a stable combustion environment for the torch 4 in the CNC flame cutting machine. In this embodiment, the number of ventilation holes 44 is preferably 6. A flame arrestor pad 45 is provided on the side of the extended baffle 42 near the torch 4.

In this embodiment, the number of receiving plates 5 is preferably 4. The receiving plates 5 are horizontal plates. The receiving plates 5 are fixedly provided with receiving baffles 51 by welding around their edges. The receiving baffles 51 prevent molten metal slag from leaking from the receiving plates 5 when they slide away from the cutting platform 2. The receiving baffles 51 are fixedly provided with a handle 52 by welding at one end near the edge of the cutting platform 2 to facilitate the sliding of the receiving plates 5.

[0043] The implementation principle of this application embodiment is as follows: A baffle plate 41 is welded onto the cutting torch 4. The baffle plate 41 is rotatably connected to the extension baffle 42 via a hinge welded on top. The positioning block 43 below the baffle plate 41 restricts the tilt of the extension baffle 42, ensuring that the extension baffle 42 can block sparks and molten metal slag splashes without affecting the normal operation of the CNC flame cutting machine. This effectively controls the diffusion range of sparks and molten metal slag splashes, thereby improving the problem of sparks or molten metal slag splashing onto the operator or equipment surface during the cutting process and improving the safety of the CNC flame cutting machine.
