High and low temperature tire cord bending fatigue testing machine cord dynamic cycling testing machine

High and low temperature cord bending fatigue testing machine
1、 Product Overview:
The testing standard of this testing machine is made according to the requirements for determining the bending fatigue of the cord. Its function is to measure the number of cycles required for the specimen to undergo repeated bending deformation until fracture at a specified bending strain and temperature.
2、 Action principle:
It is to subject the cord or rope sample to reciprocating up and down through two freely rotating guide rollers A and B under certain load conditions, causing the cord to undergo reciprocating bending fatigue, simulating the fatigue effects of repeated stretching, compression, and bending of the cord or rope in rubber products. Record the number of fracture fatigue cycles for each sample.
