Metal fire door body manufacturing method

The invention relates to a metal fire door body manufacturing method, which mainly relates to an easy assembly and a better combination stability and consistency quality structure.

The conventional fireproof door mainly has two door panels, and the heat insulating material is arranged in the two door panels to have fireproof and heat-blocking effect. Figure 5 is one of the conventional fireproof door bodies, and shows a transverse sectional view, mainly having two opposite metal door panels 1', a core material 2', a number side fireproof panel 3', a plurality of metal plates 4', a number of metal reinforcing frames 5', a number of side frames 6', and a number of side fireproof materials 7', wherein the door panel 1' is bent at the side a portion 11', a side portion 12' is vertically disposed at one end of the bent portion 11', and the core material 2' is made of a fireproof material, and the concave portion 21' is cut on both sides of the periphery; the side fireproof plate 3', the metal plate 4' Superposed on the position of the recess 21' of the core material 2'; the reinforcement frame 5' is disposed outside the core material 2'; the side frame 6' provides the door body edge seal, and the center has a recess 61'; The fireproof material 7' is provided at the position of the recess 61'.

The assembly will be as shown in Fig. 5 from top to bottom, so that one door panel 1' is placed flat and the side fire board 3', the metal plate 4', and the reinforcing frame 5' are disposed inside the corresponding side panel portion 12' of the door panel 1'. And the side plate portion 12' is spot-welded with the metal plate 4' and the reinforcing plate 5' (as shown by the dot); the core material 2' is placed above the door plate 1', and then placed on the other side. The side fire board 3', the metal board 4', the reinforcing frame 5', and the other door panel 1' are placed above, and the side panel portion 12' of the upper door panel 1' and the metal panel 4', the reinforcing frame 5' point Welding, and the metal plate 4', the reinforcing frame 5' can improve the strength of the door body, and the side fireproof material 7' is accommodated in the recess 61' of the side frame 6', and the side frame 6' The side edge of the two door panels 1' is provided with an edge sealing treatment, and the two sides of the side frame 6' are respectively spot-welded and fixed with the two door panels 1' to complete the fire door finished product.

In the foregoing structural assembly process, the core material 2' is to be cut into the concave portion 21', and the reinforcing frame 5', the side fireproof plate 3', and the metal plate 4' are first placed on the door panel 1', and the insertion process is not easy to locate and is placed. After the spot welding combination, the two door panels 1' butt joints must be spot welded to set the side frame 6' edge seal, the overall solder joints are too much, which will greatly increase the manufacturing man-hours, and lead to incomplete quality and inconsistency.
