The damping adjustment pad 10 is made of elastic material, and the wrapping area and the extrusion force of the damping adjustment pad 10 on the drum shaft 20 are increased in the process of extruding the damping adjustment pad 10 by the drum shaft 20, so that the rotation resistance of the drum shaft 20 in the damping adjustment pad 10 is also increased under the condition that the two can rotate relatively and are subjected to sliding friction force.
When the device is specifically used, firstly, a user needs to pass one end of a casing to be detected through the front end guide pipe 22 and pass through the dynamic damping type biaxial stretching mechanism 1 to pass through the rear end guide pipe 29 under the state that the bending amplitude of the arched main body expansion frame 8 is not large, and the casing to be detected is folded and stored for a certain length on the rear end guide pipe 29;
then the sleeve is extended into the rear end conduit 29, and the adjusting stud 33 is rotated through the hexagonal cap 37 of the stud, and the front end conduit 22 and the rear end conduit 29 can only slide relatively and cannot rotate relatively, so that the rear end conduit 29 slides towards the front end conduit 22 under the guidance of the double-pipe guide rail 26 and the double-pipe guide hole 36 in the rotating process of the adjusting stud 33, and the adjusting stud 33 also has a certain supporting and guiding function in the rotating process;
when the front end conduit 22 and the rear end conduit 29 are close to each other, the expansion frame hinge rings 13 at the two ends of the arch main body expansion frame 8 are also close to each other, and the arch main body expansion frame 8 has small bending amplitude towards the outer side, so that the bending amplitude of the arch main body expansion frame 8 can be further increased, the test standards of casings with different specifications are different, and the rear end conduit 29 can be adjusted to a proper position according to the specifications;
through the internal propping of the dynamic damping type biaxial stretching mechanism 1, the casing is tightly wrapped on the arched main body expansion frame 8 and the supporting roller 11, the sleeve is removed, the casing wrinkled on the rear end conduit 29 is pulled out and fixed on the next process (winding or other compression storage modes) and then the next storage process is started;
the driving force of winding can be used as a power source of the detection process and a tensile force source for testing the axial strength;
if the strength of the casing is qualified and standard high, the distance between the front end conduit 22 and the rear end conduit 29 is short, the bending amplitude of the arched main body expansion frame 8 is large, the extrusion force of the casing to the supporting roller 11 is also large at the moment, so the roller shaft 20 can slide along the annular hole 16 of the base, the rotation resistance of the supporting roller 11 is also increased at the moment because the wrapping surface and the pressure of the damping adjusting pad 10 to the roller shaft 20 are both increased, the rotation resistance is the tensile force for testing the axial strength of the casing, the extrusion force of the supporting roller 11 to the casing is the tensile force for testing the radial strength of the casing, and the axial tensile force and the radial tensile force of the device are increased and reduced simultaneously and are matched with each other.
If no tearing occurs when the casing passes through the device, the radial and axial tearing resistances of the product are qualified.
The whole working flow of the invention is just the above, and the step is repeated when the invention is used next time.
