[0002] Stamping is a forming processing method that applies external forces to plates, strips, tubes, profiles, etc. by a press and a die, causing them to undergo plastic deformation or separation, so as to obtain workpieces (stamped parts) with the required shapes and sizes.

[0003] For an existing stamping and forming device, such as a stamping device for machining of mechanical parts disclosed in the utility model patent with the application number 202122101326.1, its main structure includes a workbench, a support frame is arranged on the upper side of the workbench, a stamping cylinder is arranged on the upper side of the support frame, a stamping head is arranged in the middle of the mounting plate, the lower ends of a plurality of telescopic rods are fixedly connected to a pressing plate together, the vertical height of the pressing plate is lower than that of the stamping head, springs are sleeved on a plurality of telescopic rods, a stamping table is arranged on the upper side of the workbench, and a punching hole matching the stamping head is arranged in the middle of the stamping table; during use, a staff member can place a circular plate part to be stamped on the stamping table, and the retaining ring can limit the part. The stamping cylinder extends to work, driving the mounting plate to move downward, thereby driving the stamping head to move downward. Before the stamping head contacts the part, the pressing plate first contacts the part. At this time, the mounting plate continues to move downward, and a plurality of springs and a plurality of telescopic rods are compressed until the stamping head penetrates the part and punches a hole in the middle of the part. After stamping is completed, the stamping cylinder contracts, driving the mounting plate and the stamping head to move upward.

[0004] However, after stamping is completed by the existing stamping device, the workpiece is easily stuck in the die and difficult to take out, and manually taking out the stamped workpiece is not only very dangerous. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a stamping and forming device for engineering machinery parts that not only prevents the workpiece from being stuck in the die, ensures the stamping effect, but also can automatically discharge the material, avoids taking by the staff member by hand, and improves the safety of using the device.
