[0002] Fire doors are defined as those that have passed the fire resistance test of the new national standard GB_12955-2008 for fire doors implemented on January 1, 2009 by the laboratories designated by the Ministry of Fire Protection and the Ministry of Economic Affairs, and have obtained the verification registration certificate and authorization mark issued by the Bureau of Standards, Metrology and Inspection of the Ministry of Economic Affairs. Fire doors defined by the US NFPA and IBC specifications are any combination of fireproof door leaves, door frames, hardware and other accessories that can provide a certain degree of fire protection for the opening.

[0003] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are fireproof partitions with certain fire resistance, located between fire compartments, evacuation stairwells, vertical shafts, etc.

[0004] In addition to the functions of ordinary doors, fire doors can also prevent the spread of fire and smoke. They can prevent the spread of fire for a certain period of time and ensure the evacuation of personnel.

[0005] Wooden fire doors are made of flame-retardant wood or flame-retardant wood products as door frames, door leaf frames, and door leaf panels. If the door leaf is filled with material, it is filled with fire-proof and heat-insulating materials that are non-toxic and harmless to the human body, and is equipped with fire-proof hardware accessories to form a door with certain fire resistance.

[0006] A wooden fire door refers to a door whose door frame, door leaf frame, and door leaf panel are made of wood or wood products, and whose fire resistance limit meets national regulations.

[0007] During the production process of fire doors, it is necessary to punch holes in the raw materials of fire doors, and the raw materials need to be fixed. However, most of the raw material fixing devices for fire doors are too simple, which is not convenient for batch fixing of raw materials of the same size on the assembly line, and it is not convenient for alignment, which easily causes punching deviation.
