[0038] Working principle: First, the cylindrical copper ingot 7 to be punched is placed on the second slide 12. At this time, the fourth hydraulic cylinder 15 is activated, and the second slide 12 rises within the third guide rail 11 and the second chute 10 until the cylindrical copper ingot 7 contacts and clamps the multiple inverted trapezoidal connecting blocks 68 in the circular bracket 65. Since the multiple first springs 67 are in a compressed state, they generate elastic force to fix the cylindrical copper ingot 7. Then, the piston rod of the fourth hydraulic cylinder 15 drives the second slide 12 to move downward;

[0039] Then start the third hydraulic cylinder 610, the piston rod drives the second connecting plate 69, the first connecting plate 63, the circular bracket 65 and the cylindrical copper ingot 7 to slide along the direction of the second guide rail 61.

The outer wall of the cylindrical copper ingot 7 is smeared with stamping and stretching oil through friction with the brushes 13. When the cylindrical copper ingot 7 moves to the top of the first chute 9, the piston rod stops stretching. Simultaneously, the two screw-type support rods 83 are pressed, and the two screw-type support rods 83 move downward, causing the cylindrical copper ingot 7 to fall off from the circular bracket 65 and enter the first guide rail 2 through the first chute 9. Then, the second hydraulic cylinder 32 drives the semi-annular connecting plate 31 to move, and the semi-annular connecting plate 31 pushes the cylindrical copper ingot 7 onto the stamping groove. The semi-annular connecting plate 31 is tightly attached to the stamping groove to form a cylindrical mold. After stamping is completed, the semi-annular connecting plate 31 moves back to the back of the first chute 9.

[0040] The copper tube moves upward along with the hydraulic pipe of the punching machine 1, ready for demolding. At this time, the piston rod of the first hydraulic cylinder 51 drives the trapezoidal box 53 to move to the bottom of the copper tube, catches the demolded copper tube, moves forward to push the copper tube out, and the worker takes out the copper tube and moves it to the next process.
