Description

Technical Field

[0001] The utility model relates to the field of automobile molds, in particular to a continuous mold for rear reinforcement plates of left and right upper side beams of a pickup truck. Background Art

[0002] The main function of the upper side beam of a pickup truck is to connect the A-pillar, the front wheel housing, and the front cross beam, and to provide mounting points for the engine hood and fenders. At the same time, it can provide a drainage outlet for the water tank, and provide assistance for accidental collisions, transferring the collision force to the A-pillar. The upper side beam component is a slender structure, which contributes little to the collision. In order to meet the collision requirements, it is often necessary to design it into high-strength steel and increase the strength of other areas. Therefore, it is necessary to design a reinforcement plate in the left and right upper side beams, and the upper side beam reinforcement plate of a pickup truck has a certain curvature and includes left and right parts, which require a cutting and denting process. In addition, a right-angle connecting plate is provided at one end of the reinforcement plate, which requires stamping and bending, and a connecting hole needs to be set on the bent plate, which requires a side punching process. The current continuous die for the reinforcement plate cannot complete this type of stamping task with multiple types of complex processes, and usually requires a matching die for assistance, which increases the number of workstations and the turnover of workpieces. Therefore, the existing continuous die needs to be designed and improved. Utility Model Content
