Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal stamping dies, and more specifically, to a sheet metal stamping die with automatic positioning and calibration. Background Art

[0002] Sheet metal is a processing technology that mainly performs a series of comprehensive cold processing on metal sheets, including processes such as shearing, punching, compounding, folding, riveting, splicing, and forming. Its remarkable feature is that the thickness of the same part is consistent. Sheet metal processing is widely used in many fields, such as automobile manufacturing, aerospace, electronic equipment manufacturing, agricultural machinery manufacturing, and other industries.

[0003] When performing sheet metal stamping on metal sheets, sheet metal stamping dies are generally used. During the use of sheet metal stamping dies, feeding and positioning calibration are usually two independent steps. After the feeding is completed, the sheet metal parts need to be taken out separately for positioning calibration, and then put into the stamping equipment again for stamping processing. This traditional processing method not only has a cumbersome process, but also the traditional positioning calibration method usually relies on the experience and skills of operators. Due to the limitations of manual calibration, it will affect the accuracy and stability of stamping processing. Summary of the Utility Model
