Description

[0002] Steel cord is a reinforcing material used in rubber products such as tires. It is usually made of high-carbon steel and has high strength, high toughness, and good fatigue resistance. It is generally made of multiple steel wires twisted together. Depending on the application requirements, there can be different twisting structures and specifications. In order to improve the mechanical properties of steel cord and its adhesion to the tire, the steel wires are pre-deformed during the twisting process. Currently, there is a deformation structure using the steel cord deformer disclosed in patent number CN220149956U. Its main mode is that the deformation column and the guide wheel are both inclined. However, it has been found that the deformation effect of this structure is insufficient, the stress is not uniform enough, and there is still room for improvement in the deformation effect and the guide wheel efficiency.
