[0023] See also Figures 1-4 , the utility model provides a technical solution:
[0024] A machine tool fire extinguishing device includes a machine tool housing 101, a lifting frame 201 fixedly connected to one side of the machine tool housing 101, and a fire extinguishing cover 205 mounted on the bottom of the top side of the lifting frame 201. The bottom side of the fire extinguishing cover 205 is in contact with the top side of the machine tool housing 101. The top side of the fire extinguishing cover 205 is provided with multiple heat transfer plates 210. The outer edges of the heat transfer plates 210 are wrapped with multiple coils of heat pipes 206. Liquid heat dissipation agent flows within the heat pipes 206. In this embodiment, the heat pipes 206 are generally made of copper to achieve good heat transfer performance. The heat dissipation agent flowing in the heat pipes 206 can be a common heat dissipation liquid such as water or silicone oil. It is used to quickly absorb heat from the heat transfer plates 210, cool the interior of the machine tool housing 101, and eliminate the three elements of combustion, thereby achieving the purpose of extinguishing the fire.
[0025] The top side of the machine tool housing 101 is provided with multiple working position slots 102, and the top side of the fire extinguishing cover 205 is provided with multiple heat transfer ports 211. The inner wall of each heat transfer port 211 is fixedly connected to the outer edge of a heat transfer plate 210, and each heat transfer plate 210 directly faces a working position slot 102, allowing each heat transfer plate 210 to absorb heat from within a specific working position. A sealing ring 104 is fixedly connected to the outer edge of the machine tool housing 101, and a sealing top ring 103 is fixedly connected to the top side of the sealing ring 104. The side of the lifting frame 201 facing the machine tool housing 101 contacts the outer edge of the sealing ring 104. A sealing groove ring 204 is fixedly connected to the bottom side of the fire extinguishing cover 205, and a lifting sealing ring 203 is fixedly connected to the inner wall of the bottom side of the sealing groove ring 204, with the bottom side of the lifting sealing ring 203 in close contact with the top side of the sealing top ring 103. In this embodiment, the provision of an elastic lifting seal ring 203 and a sealing top ring 103 prevents external air from entering the combustion area, further accelerating the extinguishing of the fire. A plurality of evenly distributed heat dissipation brackets 208 are fixedly connected to the top side of the fire extinguishing housing 205. The outer walls of all heat dissipation pipes 206 are fixedly connected to the inner walls of the heat dissipation brackets 208. A collection sleeve 209 is fixedly connected to each end of each heat dissipation pipe 206. A liquid pump 212 is fixedly connected to one side of the fire extinguishing housing 205. The output end of the liquid pump 212 is connected to one end of the heat dissipation pipe 206, and the input end of the liquid pump 212 is connected to the corresponding collection sleeve 209. The provision of the liquid pump 212 allows the heat dissipation agent to quickly pass through the heat dissipation pipe 206, accelerating the heat absorption effect on the heat transfer plate 210.
[0026] A lifting cylinder 207 is fixedly connected to the top of the lifting frame 201. The output end of the lifting cylinder 207 is fixedly connected to a lifting connecting frame 202. The bottom of the lifting connecting frame 202 is fixedly connected to the fire extinguishing cover 205. In this embodiment, the fire extinguishing cover 205 is lowered by the lifting cylinder 207 to extinguish the fire only after the machine tool catches fire. Normally, the fire extinguishing cover 205 is raised, exposing the machine tool housing 101.
[0027] It should be noted that, as a machine tool fire extinguishing device, the present invention achieves the following technical effects: by setting the heat transfer plates 210 corresponding to each workstation of the machine tool, after the fire extinguishing cover 205 descends to cover the entire machine tool shell 101, the heat transfer plates 210 are extended into the machine tool workstations, and the heat in the workstations is conducted to the outside of the fire extinguishing cover 205, and in conjunction with the setting of the heat dissipation agent flowing in the heat dissipation pipe 206, the heat conducted on the heat transfer plates 210 is quickly taken away, so that a closed low-temperature space is formed inside the machine tool, thereby preventing the fire from continuing to develop, and completing the fire extinguishing work while ensuring the internal structure of the machine tool.
