Preparation method of special-shaped veneer

The invention discloses a preparation method of a special-shaped veneer, and relates to the field of veneer preparation. The preparation method of the special-shaped veneer comprises the following steps that a long veneer flat plate is placed on a lower mold of a molding press; the upper mold and the lower mold are heated, so that the temperature of the long veneer flat plate is kept at 50-80 DEG C in the mold pressing process; pressing the upper die downwards; the top surface of the upper mold is connected with a plurality of linearly arranged hydraulic cylinders; the multiple hydraulic cylinders comprise two side cylinders fixedly connected with the two ends of the top face of the upper die correspondingly, and at least one main cylinder arranged between the two side cylinders. And when the pressure of the main cylinder reaches 11-12 Mpa and the pressure of the side cylinders reaches 7-8 Mpa, pressure maintaining is conducted, and after pressure maintaining is finished, the special-shaped veneer is manufact
