The invention discloses a combination of molding dies and a molding process for a double-curved bumper, which is suitable for a bumper which is a hollow part with two ends open and has reinforcing ribs inside which are parallel to the thickness direction and extend along the length direction. The forming die combination of the bumper includes a primary bending die, a secondary bending die, a rib cutting punching die and a shaping die. Through the forming die combination of the double-arc bumper, the bending of the bumper’s secondary radian can be realized, and the double-curve is completed. The processing and molding of the bumper is simple, easy to implement, high processing efficiency, less mold repair times, strong product stability and consistency, high product quality, and guaranteed product quality and production efficiency. It is suitable for large double-curved bumpers. Mass production, strong practicability.
Description
technical field [0001] The invention belongs to the technical field of stamping and forming, and in particular relates to a forming die combination and forming process of a double arc bumper. Background technique [0002] The car bumper is the main safety component that protects the occupants and the car body when the car collides. The structural design of the bumper should not only take into account the safety performance, but also the structure of other parts around the bumper and the overall appearance of the car. design. Various automobile bumpers currently on the market are designed to have a curved structure in order to match the shape of the hood and the front skin, but generally only one arc, that is, only one direction is bent. In order to better adapt to the design of the front of the car, a double-curved bumper has appeared, which is bent in two mutually perpendicular directions, with a complex structure and great difficulty in forming. The molding process of th...
