The heat generation is mainly concentrated in the deformation zone and sizing zone, in which the deformation area is mainly deformation heat work, the sizing is mainly the role of friction heat, drawing about 70% of the heat is about deformation heat, the remaining about 30% Frictional heat, but the impact of the two kinds of heat on the system is completely different, in which the deformation of the metal wire in the wire structure changes, the mold is much larger than the hardness of the metal so almost no changes in the crystal structure So it is almost no heat, so the mold heat generated by the deformation of the metal heat and heat generated by the heat, because the process of drawing high-speed drawing into the mold into the mold and the line temperature is much lower than the mold Of the temperature, when the heat generated when the deformation is more heat is to make the wire temperature rise rather than the mold temperature rise, when the wire temperature increases into the mold after the second part of the deformation zone is the second half and sizing Here is the area where the system temperature is the highest.

And a considerable amount of deformation heat is taken away with the wire leaving the mold, but the residual heat through the deformation zone and sizing the conduction of the system to make heat, so that the mold inlet cone and lubrication cone temperature, The temperature distribution of the inlet cone and the lubrication cone can have a significant effect on the lubrication of the lubricating powder.
