The invention discloses a forming die assembly and a forming process of a double-radian bumper. The forming die assembly and the forming process are suitable for bumpers which are hollow parts with openings at two ends and are internally provided with reinforcing ribs parallel to the thickness direction and extending along the length direction. The forming die assembly of the double-radian bumpercomprises a primary bending die, a secondary bending die, a rib cutting and punching die and a shaping die. Through the forming die assembly of the double-radian bumper, double-radian bending of the bumper can be achieved, machining forming of the double-radian bumper is completed, machining operation is easy, implementation is easy, the machining efficiency is high, the die repairing frequency islow, product stability and uniformity are high, product quality is high, product quality and production efficiency are ensured, large-batch production of double-radian bumpers can be achieved, and practicability is high.
Description
technical field [0001] The invention belongs to the technical field of punching and forming, and in particular relates to a combination of forming dies and a forming process of a double-curved 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 car bumpers currently on the market are designed to be curved in order to match the shape of the hood and the front skin, but generally only one arc, that is, only bend in one direction. In order to better adapt to the exterior design of the front of the car, a double-curved bumper is now available, which is bent in two mutually perpendicular directions. The structure is complex and difficult to form. The molding process of the double-...
