[0002] Automobile longitudinal beam is the load-bearing part of the automobile, and it is also a safety part during the driving process of the automobile. Therefore, the automobile longitudinal beam is usually made of high-strength steel plate. Rebound phenomenon, so after the longitudinal beam is bent and formed, it is easy to get stuck on the lower mold base due to the rebound force at both ends of the longitudinal beam, and it is difficult to remove

The invention discloses a forming die for an automobile high-strength steel plate longitudinal beam, and relates to the technical field of automobile longitudinal beam machining. The forming die comprises a bending forming die for the longitudinal beam; two movable die ends move upwards obliquely through retraction of a hydraulic cylinder piston rod by means of a first transmission component and asecond transmission component to be matched with downward movement of a pressing die head, and the two ends of the longitudinal beam are bent; and the two movable die ends move downwards obliquely through stretching of the hydraulic cylinder piston rod by means of the first transmission component and the second transmission component to be matched with upward movement of the pressing die head, and the bent longitudinal beam is ejected out of the position between the two movable die ends. Through the matching of the structures, a traditional lower die holder fixed in position is replaced by the two movable die ends capable of moving obliquely, so that the bent longitudinal beam can be ejected out of the position between the two movable die ends when the two movable die ends move downwardsobliquely and is matched with upward movement of the pressing die head.
Description
technical field [0001] The invention relates to the technical field of automobile longitudinal beam processing, in particular to a forming die for automobile high-strength steel plate longitudinal beams. Background technique [0002] The car longitudinal beam is the load-bearing part of the car, and it is also the safety part during the driving process of the car. Therefore, the car longitudinal beam is usually made of high-strength steel plate. One of the characteristics of the high-strength steel plate longitudinal beam is the high strength of the plate, which is easy to occur Springback phenomenon, so after the longitudinal beam is bent and formed, it is easy to get stuck on the lower mold base due to the rebound force at both ends of the longitudinal beam and it is difficult to remove it. Contents of the invention [0003] The object of the present invention is to provide a forming die for the longitudinal beam of the high-strength steel plate of the automobile, which ...
