Technical Field
[0001] The utility model relates to a cold pressing device, in particular to a cold pressing forming device for a wooden door. Background Art
[0002] In order to ensure the firmness of the adhesion between the various panels of the wooden door, or for the flatness and stability of the wooden door, the wooden door generally needs to be pressed and fixed as a whole during the production process. Conventional wooden door cold pressing generally uses a large cold press machine to drive the pressing plates through a hydraulic cylinder to press the surface of the wooden door. However, due to the size of the wooden door, the shape of the wooden door, and the position where the user places the wooden door, it is very easy for the pressing plate driven by the hydraulic cylinder to fail to press the surface of the wooden door evenly, and it is very easy for the force to be uneven or the edge of the wooden door cannot be fully stressed, resulting in partial bending or cracking of the various panels of the wooden door after pasting.
