The left and right ends of the material discharge chute 2 are provided with second sliding grooves 30. Two second sliding blocks 31 are fixedly connected to the two support seats 26. The two second sliding blocks 31 slide and cooperate with the two second sliding grooves 30 respectively, which supports the support seats 26 and facilitates the stable back-and-forth sliding of the support seats 26.

[0027] Specifically, during the movement of the U-shaped frame 4, the U-shaped frame 4 drives the U-shaped seat 28 to move, and the U-shaped seat 28 slides on the support seat 26. At the same time, the U-shaped seat 28 drives the support seat 26 to move back and forth, and the support seat 26 supports the bottom of the U-shaped frame 4 to prevent the U-shaped frame 4 from bending under the force of stamping.

[0028] In summary, when using the overall equipment: The sheet metal part is placed on two support plates 9, and the position of the sheet metal part to be stamped is aligned with the position of the blanking groove 2. Then, the second electric cylinder 11 pushes the clamping plate 12 downward to press and fix the sheet metal part. Then, the first motor 16 drives the first screw 15 to rotate. The rotation of the first screw 15 causes the convex seat 14 to slide back and forth inside the convex groove 13. The convex seat 14 drives the support frame 3, U-shaped frame 4, stamping head 7 and stamping die 8 to adjust their front and back positions. The second motor 21 drives the second When the screw 20 rotates, the second screw 20 rotates, causing the first slide block 19 to slide inside the first slide groove 18. The first slide block 19 drives the U-shaped frame 4, the stamping head 7, and the stamping die 8 to adjust their left and right positions, adjusting the stamping head 7 and the stamping die 8 to the position where the sheet metal part needs to be stamped. Then, the first electric cylinder 5 pushes the stamping head 7 to move downward. Through the cooperation of the stamping head 7 and the stamping die 8, the stamping is performed on the sheet metal part. The waste generated by stamping falls into the collection box placed below through the mounting seat 6, the discharge port 29, and the discharge groove 2.
