A punch 1 is arranged in the combining cylinder 2, and the punch 1 is output from the top of the combining cylinder 2. A piston shaft 3 for driving the punch 1 to move is arranged in the driving cylinder 6, and the piston shaft 3 enters the combining cylinder 2 from the top of the driving cylinder 6 and is fixed at the bottom of the punch 1. A connecting plate 7 is also provided at the bottom of the driving cylinder 6.
The pipe body sensor 5 is arranged in the driving cylinder 6 along the axial direction, the bottom of the pipe body sensor 5 extends to the bottom of the driving cylinder 6 and is flush with the bottom of the driving cylinder 6, the upper end of the pipe body sensor 5 enters the combining cylinder 2 after being output from the upper port of the driving cylinder 6, and the piston shaft 3 is sleeved on the outer ring of the pipe body sensor 5 and moves relative to the pipe body sensor 5 in the reciprocating motion process of the driving punch 1.
A metal cylinder 4 is provided inside the piston shaft 3, and the metal cylinder 4 is preferably made of copper. The metal cylinder 4 extends inside the piston shaft 3 from the upper port of the piston shaft 3 downward to the lower port of the piston shaft 3. When the piston shaft 3 drives the punch 1 to reciprocate, the metal cylinder 4 and the tube body sensor 5 are driven to move relatively.
Referring to fig. 2, the tube sensor 5 includes a tube, which is preferably made of ceramic. Coat by interior and outer coating has two-layer copper product's coating on the inner wall of body: the first copper layer 8 and the second copper layer 10 are further coated with an insulating layer 9 for insulation between the first copper layer 8 and the second copper layer 10, and a capacitor structure is formed between the first copper layer 8 and the second copper layer 10 due to the existence of the insulating layer 9. The first copper layer 8, the second copper layer 10 and the insulating layer 9 extend downwards from the upper port of the tube body to the lower part of the tube body along the axial direction of the tube body on the inner wall of the tube body, and the first copper layer 8, the second copper layer 10 and the insulating layer 9 are located on the action track of the metal cylinder 4.
