Description

Technical Field

[0001] The utility model relates to the technical field of fire door production and manufacturing, in particular to a fire door hot pressing device. Background Art

[0002] 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 usually installed in some closed places such as stairways, elevator rooms, cable shafts, and smoke exhaust ducts, and have the function of preventing the spread of fire and smoke. When a fire occurs, fire doors can effectively delay the spread of fire and provide valuable time for personnel evacuation; fire doors can be divided into wooden fire doors, steel fire doors, steel-wood fire doors and fire doors of other materials according to their materials; they can be divided into normally closed fire doors and normally open fire doors according to their opening status. Normally closed fire doors are generally installed in places such as stairways, elevator rooms, and cable shafts, and remain closed. They are heavy when pushed open. Normally open fire doors are usually in an open state and can close automatically in case of fire, playing the role of smoke and fire blocking. At present, when fire doors are glued, hydraulic cylinders are mainly used to push semi-finished fire doors into the fire door hot press for high-temperature shaping and gluing during the pressing process. However, this method will cause deviation during the process of moving and hot pressing the semi-finished fire doors, making the fire doors unevenly glued, thereby affecting the fire performance of the fire doors; for example, "Utility Model CN211710281U A fire door hot pressing device. The device is provided with a positioning mechanism, which can drive two symmetrical positioning cylinders to work through an air compressor, push and pull the movable positioning block to clamp the fire door, position the workpiece, and prevent the phenomenon of misalignment, thereby ensuring the fireproof quality of the fire door; the device is provided with two heating sources, and the movable electric heating strip and the fixed electric heating strip work at the same time, and two-way heating is performed to improve the heating speed, which can greatly improve the heating speed of the workpiece, thereby improving the production efficiency of the fire door; the device is provided with two symmetrically arranged support rods, and the support rods are slidably connected with a sliding block adapted thereto, which can effectively limit the downward pressing position of the movable pressing plate, and avoid the phenomenon of inaccurate hot pressing caused by the left and right shaking during the downward pressing process.
