[0002] Compared to ordinary doors, fire doors also have the function of preventing the spread of fire and smoke, ensuring the safe evacuation of personnel. Fire doors are generally made of composite panels, so cold presses are usually used in their application. A cold press is a device that processes and shapes the material at room temperature and generally uses hydraulic transmission.

[0003] A cold press for sheet metal processing is disclosed in document CN221736464U, including a cold press table. The top of the cold press table has an installation groove, and a dust removal frame is snapped into the inner wall of the installation groove. The dust removal frame has a first dust removal chamber and a second dust removal chamber inside. Brush bristles are fixedly connected to the inner wall of the dust removal frame, and dust removal holes are opened in the inner wall of the dust removal frame.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The cold press mentioned above has a dust removal frame on its cold pressing table, and the dust removal frame is equipped with brushes. The dust removal frame and brushes are used to remove dust from the board. However, during use, it lacks a structure for limiting and aligning multi-layer boards, which requires the staff to manually limit and align the multi-layer boards. Its functionality is poor.

[0006] 2. The cold press mentioned above has a dust removal frame on its cold pressing table, and the dust removal frame is equipped with brushes. The dust removal frame and brushes are used to remove dust from the board. However, during use, it is not convenient to control the temperature of the board, and it cannot avoid the cold pressing effect of the board due to temperature changes. Its functionality is poor.

[0007] To address these issues, we provide a cold pressing machine for fire door panels. Utility Model Content
