Device and method for testing softness of wire-guide metal hose

[0028] Describe the present invention below in conjunction with specific embodiment:

[0029] The structural parameters of the wire-conducting metal hose in this embodiment are: outer diameter the inside diameter of Pitch 6.5mm±0.5mm, minimum bending radius ≤60mm.

[0030] figure 1 Shown is the metal hose softness test principle tooling, the metal hose is coiled on the diameter On the disk, the metal hose and the outer surface of the disk are completely in conformity. The metal hose is erected and perpendicular to the ground. A weight with a mass of 0.95kg and a height of 300mm at the lower end is hung on the uppermost end of the metal hose. Remove the disk, and use the height where the weight falls to indicate the softness of the metal hose. When testing the softness of metal hoses, it is required to test a point every 5m. For metal hoses of 50m or longer, the strength of the test directly using the principle tooling is relatively high, the test efficiency is low, and it
