[0002] One of the main functions of coal mine sealing rings is to effectively isolate external flammable gases and prevent them from entering the interior of electrical equipment. This can prevent the accumulation of flammable gases inside the equipment and reduce the risk of fire or explosion. Since it is difficult to lower large equipment into coal mines, the current production of explosion-proof sealing rings in coal mines is generally done manually, and during the production process, tools such as files and iron cones are needed to cut the explosion-proof sealing rings into the required shape and size. In this process, the following problems are common:

[0003] 1. Difficult to ensure accuracy: When manually making explosion-proof sealing rings, due to factors such as the operator's technical level, experience, and fatigue level during work, the size and shape of the produced sealing rings may deviate, making it difficult to meet precise requirements. This may affect the sealing effect of the sealing ring and increase the risk of gas leakage in the mine.

[0004] 2. Low production efficiency: Compared with mechanized or automated production methods, manual production of explosion-proof sealing rings is slower and less efficient. This may hinder the mine production progress and affect the overall production plan.

[0005] 3. Unstable quality: During the manual production process, due to individual differences among operators and changes in the working environment, the quality of the produced explosion-proof sealing rings may be unstable. Some sealing rings may meet the requirements, while others may have defects, increasing the risk during use.

[0006] 4. Great safety hazard: The underground working environment is complex and there are many dangerous factors, such as gas, coal dust, etc. When manually making explosion-proof sealing rings, workers need to perform delicate operations underground for a long time, which not only increases the labor intensity of workers, but also may cause safety accidents due to careless operation.
