Description

Technical Field

[0001] This utility model relates to the field of automotive roof molding technology, and in particular to a three-dimensional automotive roof vacuum adsorption molding device. Background Technology

[0002] The forming of car roofs is usually done by stamping. Stamping refers to the processing and forming method that uses a press and mold to apply external force to sheet metal, strip, tube and profile, etc., to make them plastically deform or separate, thereby obtaining a workpiece with the required shape and size. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and sheets.
