Abstract
The invention relates to the field of metal plastic shaping. The invention discloses a continuous squeezing method of directly cooling squeeze wheel race and material stop block surfaces. A squeeze wheel or a material stop block is cooled with the method that liquid cooling medium directly cools the surface of squeezed metal covered by a squeeze wheel groove or the outer surface of the material stop block; before the squeezed metal covered by the squeeze wheel groove rotates to a compaction wheel and the cooling medium contacts the squeezed metal rod material, no cooling medium is left on the surface of the squeezed metal covered by the surface layer of the squeeze wheel. The continuous squeezing method of the invention more effectively lowers the temperature of the squeeze wheel and the material stop block, improves the production rotation speed of the squeeze wheel, improves the production efficiency of the device and improves the utilization ratio of the material and the service life of the squeeze wheel.
