Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a loading and unloading mechanism for a stamping device. Background Technology

[0002] Metal stamping is a processing method that uses dies and stamping equipment to apply pressure to metal sheets, causing them to undergo plastic deformation or separation, thereby obtaining parts with specific shapes, dimensions, and properties. Stamping is characterized by high processing speed and high precision, and is widely used in automobile manufacturing, electronic product housings, and other fields.

[0003] Chinese Utility Model Patent Publication No.: "CN 220880118 U" discloses a stamping device for metal parts processing. When performing stamping processing of metal parts, the device can first adsorb the raw material sheet onto the bottom end of the front electric suction cup, and then operate the rotary motor to drive the rotating block to rotate synchronously by 180 degrees. At this time, the raw material sheet is driven to the top of the lower mold, and the electric suction cup is de-energized to place the raw material sheet into the stamping cavity of the lower mold. Then, the translation motor is operated to drive the gear at its output end to rotate synchronously.

[0004] The above-mentioned device uses an electric suction cup to adsorb and load metal raw materials. However, some metal raw materials cannot be magnetically attracted. Therefore, the magnetic loading and unloading of the electric suction cup has certain limitations. In addition, there are some scraps after the metal raw materials are stamped. The above-mentioned device does not process them. During the stamping process, the stamped metal workpiece and the scraps are easily unloaded together, which requires subsequent sorting and affects the metal stamping efficiency.
