The invention can save manpower and effectively improve work efficiency.
Description
technical field [0001] The invention relates to the technical field of production and manufacture of tunnel protective doors, in particular to a door panel trimming device for tunnel protective doors. Background technique [0002] In high-speed rail and subway tunnels, in order to resist the air pressure brought by the passage of trains in the tunnel, so that the internal equipment is intact and free from the hazards of air pressure shock waves, protective doors are often installed. [0003] During the production of tunnel protection doors, accessories such as door panels, door frames and hinges need to be mass-produced separately; after the door panels of the protection doors are molded according to the temperature, pressure and pressure holding time required by the process, they need to be trimmed to remove excess Fly edge, trim the edge of the door panel to a flat state, and then proceed to the next process. When the door panel is trimmed, the staff uses grinding wheels ...
