When the slider 2212 moves to the front end of the movable slide rail 2209, it stops moving, and the material picking position is determined, which is located directly above the sheet metal. When picking up the material, the single-axis cylinder 2211 is started, and the single-axis cylinder 2211 cooperates with the material picking suction cup 2213 to suck the sheet metal, and then the single-axis cylinder 2211 is retracted.

In the process of the sheet metal part moving toward the top mold 15 and the bottom mold 14, the first positioning plate 2218 will contact the second positioning plate 2215 to position the rearmost side of the sheet metal part when it moves. The first positioning plate 2218 limits the sheet metal part to the middle position of the top mold 15 and the bottom mold 14. At this time, the movement of the sheet metal part is stopped, so as to ensure the position of the sheet metal part. At the center position of the top mold 15 and the bottom mold 14, start the single-axis cylinder 2211 to drive the sheet metal part down to the bottom mold 14, release the material suction cup 2213, and then put the sheet metal part into the bottom mold 14.
