At this time, the punching head 9 can be disassembled and replaced to adapt to the use of punching cylinders 76 with different inner diameters, thereby realizing the stamping processing of catheters of different sizes, thereby improving the scope of application of the device.

[0068] Working principle: When using the device, first, Figure 1-Figure 11 As shown, the metal segment material to be processed is placed in the punching cylinder 76, and then the motor 1 610 and the motor 2 8 are started through the control cabinet 3.

[0070] Until the cam 612 pushes the top plate 65 to move the maximum distance, the end of the punch head 9 passes through the metal segment material and contacts the positioning rod 622. At this time, the punch head 9 completes the rotation and punching of the metal segment material.
