Description

Technical Field

[0001] The utility model belongs to the technical field of automobile front longitudinal beam processing, in particular to a punching concave rib tool for automobile front longitudinal beam. Background Art

[0002] The longitudinal beam is a relatively important metal component on a car. It runs from the front to the rear of the car. After opening the engine compartment, it supports the engine. The two rectangular pillars in the same direction as the car body are the front longitudinal beams of the car.

[0003] When the existing stamping rib tooling processes the front longitudinal beam of an automobile, the front longitudinal beam workpiece to be stamped is placed on the lower die, and the upper die is driven to move downward by the output shaft of the cylinder in the energized state. The upper die in the descending state performs the first stamping on the front longitudinal beam workpiece to be stamped placed on the lower die, and the operator trims the edge of the front longitudinal beam workpiece after the first stamping, and then performs a second stamping on the trimmed front longitudinal beam workpiece, so that the processing of the automobile front longitudinal beam is completed. However, the automobile front longitudinal beam is in a deformed state after being stamped and is engaged with the module of the lower die. Among the existing production equipment, there are old-fashioned stamping machines that do not have a lifting mechanism. The operator needs to use tools such as wrenches to lift the engaged automobile front longitudinal beam to complete the unloading of the automobile front longitudinal beam, which makes it more laborious for the operator to tilt the automobile front longitudinal beam and affects the processing efficiency of the device on the front longitudinal beam workpiece. Therefore, a stamping tool that is easy to modify is proposed. Utility Model Content
