Description

Technical Field

[0001] The utility model relates to the field of sheet metal stamping, in particular to a sheet metal stamping tool. Background Art

[0002] Sheet metal stamping tooling is an indispensable part of the sheet metal stamping process, which involves the mold, fixture and related auxiliary equipment during the stamping process. The main function of sheet metal stamping tooling is to provide a stable processing environment to ensure the quality and precision of stamped parts. It can keep the material in the correct position and shape during the stamping process to prevent the material from moving or deforming during the processing. The mold is one of the most important tools in the stamping process. It is designed according to the shape and size of the product and is used to punch the material into the required shape.

[0003] A sheet metal stamping tool disclosed in the Chinese utility model (Announcement No.: CN219724249U) includes an operating table and a stamping device. The bottom of the base is movably equipped with an anti-slip cover, and the bottom of the operating table is provided with a collecting device. The upper and lower dies can be easily disassembled through the cooperation of bolts and threaded holes, and different dies can be replaced according to different needs. The anti-slip cover at the bottom of the support column prevents the device from sliding, thereby improving the stability of the device.

[0004] In the above technical solution, the upper and lower dies can be disassembled and replaced with different dies through the cooperation of bolts and threaded holes. However, when using it, the operator usually needs to hold the end of the sheet metal away from the stamping with his hand and place it on the stamping die for stamping. Although this method is simple, it has many shortcomings. For example, the sheet metal and the lower die of the tooling cannot be placed flat, resulting in local deformation during stamping. Therefore, a sheet metal stamping tooling is now proposed. Utility Model Content
