[0003] In the prior art, the stamping process of sheet metal parts is usually to move the sheet metal part above the stamping die, fix the sheet metal part through a clamping device, and then start stamping. Some sheet metal parts need double-sided stamping and require flipping. After removing the sheet metal part from the die and flipping it, it will increase additional working steps, resulting in a delay in work efficiency. At the same time, removing the sheet metal part from the die and then flipping it easily causes damage to the die and the sheet metal part. Therefore, this application provides a rotatable sheet metal part stamping clamping device to meet the requirements. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a rotatable sheet metal part stamping clamping device to solve the existing stamping process of sheet metal parts. Usually, the sheet metal part is moved above the stamping die, fixed through a clamping device, and then stamping starts. Some sheet metal parts need double-sided stamping and require flipping. After removing the sheet metal part from the die and flipping it, it will increase additional working steps, resulting in a delay in work efficiency. At the same time, removing the sheet metal part from the die and then flipping it easily causes damage to the die and the sheet metal part.

After the sheet metal part is completely separated from the stamping die, start the driving part 11, drive the rotating shaft 10 to rotate. The rotating shaft 10 is installed on one side of the connecting plate 9 close to the middle of the clamping table 1 and is rotatably connected to the connecting plate 9.
