The Main Reasons For Wire Breakage In Drawing Dies Include The Following Points

Die wear: During long-term use, drawing dies will naturally wear out due to friction, resulting in plastic deformation and fatigue cracks on the die surface, which affects its normal service life.

Die damage: Dies may be damaged due to certain reasons or accumulate damage to a certain extent, making them unable to continue serving. This situation is called die failure.

Stress concentration: During the drawing process, if the force is overly concentrated in a certain area, it may cause the stress in that area to exceed the wire's tolerance, leading to breakage.

Temperature impact: Frequent wire breaks in winter may be due to the oil in use being affected by temperature, with decreased permeability and adhesion, resulting in uneven coating and insufficient anti-wear protection.

Preventive and solution measures: 

Regular inspection and maintenance: Regularly inspect the wear condition of the drawing dies, and replace severely worn dies in a timely manner to avoid wire breakage caused by die damage.

Proper use of lubricating oil: Select appropriate lubricating oil and regularly check its penetration and adhesion to ensure sufficient anti-wear protection during the drawing process.

Adjust process parameters: Adjust process parameters based on the drawing principle to ensure the service life of the dies and the drawing quality of the wire.
