Fireproof door sheet and manufacturing process thereof
The invention relates to a fireproof door sheet and a manufacturing process of the fireproof door sheet. The fireproof door sheet comprises a left door leaf and a right door leaf. A left door rear board comprises a transverse portion and a vertical portion, the tail end of the vertical portion is downwards and outwards bent to form a first structure, and the tail end of the transverse portion is inwards bent to form a second structure; a left door front board comprises a transverse portion and a vertical portion, the tail end of the transverse portion is upwards and inwards bent to form a third structure, and the tail end of the vertical portion is outwards bent to form a fourth structure; the first structure and the third structure are matched; the second structure and the fourth structure are matched. A right door rear board comprises a transverse portion and two vertical portions, the two vertical portions are arranged in the same direction, the tail end of one of the vertical portions is outwards bent to form a fourth structure, and the tail end of the other vertical portion is downwards and outwards bent to form a first structure; a right door front board comprises a transverse portion, one end of the transverse portion is inwards bent to form a second structure, and the other end of the transverse portion is inwards bent to form a third structure; the first structure is matched with the third structure; the second structure is matched with the fourth structure. The fireproof door sheet and the manufacturing process of the fireproof door sheet reduce the production cost and improve the production efficiency.
