Contact mechanics, heat generation die

Contact mechanics is a study of the deformation of parts that come into contact with each other at one or more points. An important part is to avoid the stresses that occur perpendicular (normal direction) or parallel (tangential direction) to the contact surface. In the case of drawing stones, the wire will be deformed by pulling it through a cone-like structure. During this deformation process, the temperature can rise sharply in a short time. If the temperature becomes too high, the wear process will increase significantly. A correct choice of the materials surrounding the diamond drawing stone can greatly improve its lifespan, up to 300%. Physixfactor has extensive experience to realize this.

Temperature prediction in wire die

The FEM simulations of wire dies provide results that can be used to improve the production process. The opening angle and pulling speed can be varied in the software, as well as the friction coefficient. In this way, the results of a simulation provide cost savings for the wire drawing process. These simulations improved the speed by 25% for a process to make jet wires. In addition, the service life of the product has increased by more than 300%. The competitive position is therefore assured. Significant improvements have also been achieved for copper wire drawing, ask Physixfactor about this.

 

Heat generation wire die.

Drawing dies are used for the manufacture of metal wires for all kinds of applications. Wear on drawing dies must be low in order to keep the production lines running for a long time before they have to be shut down to replace the worn drawing dies. Simulations can map the quality of the drawing stones, and by making the right choice of the physical aspects of the drawing process and the material properties of the coating of the diamond stones, the service life or lifespan of the drawing stone can be greatly increased.
