The invention belongs to the field of high-temperature equipment and provides visual hot-forming equipment. The middle of a front door of the hot-forming equipment is provided with a window, aluminumsilicate fiber cotton is attached to the outer periphery of the window and surrounds the window to form a closed ring, and a pair of guide rails are symmetrically mounted on the outer periphery of thealuminum silicate fiber cotton. A glass door is attached to the guide rails, the outer side of each guide rail is provided with an annular groove in fixed connection with the corresponding guide rail, an opening direction of each groove faces the front door of the hot-forming equipment, each groove is internally provided with an inflatable seal strip, and the height of each groove is smaller thanthat of the corresponding inflated inflatable seal strip. When the inflatable seal strips are not fully inflated, the glass door is capable of sliding along the guide rails; when the inflatable sealstrips are inflated, the glass door and the front door of the hot-forming equipment are connected hermetically. The visual hot-forming equipment is applicable to visualization in a product forming process and heat loss control in feeding and taking of large-batch products.
