Description

Technical Field

[0001] The invention relates to the field of stamping technology, and in particular to a stamping device and a method for stamping automobile stamping parts with a guide support. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

[0003] The prior art (CN118455410A) discloses a stamping device for automobile stamping parts with a guide column, which realizes stamping of automobile profile plates to be processed by moving a movable punch seat toward a fixed die seat, and adopts a concave groove to place the automobile profile plate, which can prevent the automobile profile plate from shifting during the stamping process and improve the yield rate of stamping parts; the top fixed seat, the middle movable seat, and the bottom fixed seat of the guide drive mechanism are respectively connected to the stamping drive column, the movable punch seat, and the fixed die seat. During stamping, it is only necessary to control the extension of the stamping drive column. The downward stamping of the movable punch seat can be achieved by driving the guide pillar, and the moving direction is determined by driving the guide pillar to ensure the alignment of the stamping position, thereby ensuring the stability of the movable punch seat during movement and improving the stamping quality of the stamped parts. The airflow control mechanism of the shaping and demoulding mechanism is used to control the gas pressure between the movable punch seat and the fixed die seat, thereby avoiding negative pressure deformation during demoulding of the automobile stamping parts, and quickly cooling the automobile stamping parts after stamping is completed.
