The cooperation between the driving gear 17 and the first gear 18 enables the first pressure wheel 11 and the second pressure wheel 12 to rotate synchronously in the opposite direction under the drive of the hydraulic motor 13, thereby The aluminum wire is squeezed and thinned by the first pressing wheel 11 and the second pressing wheel 12. A first gear 18 is provided on the outer side of the first fixed plate 5, and a second gear 19 meshing with the outer side of the first gear 18 is provided on the outer side of the third fixed plate 7. By cooperating with the first gear 18 and the second gear 19, the first pressing wheel 11 and the second pressing wheel 12 can be driven by the hydraulic cylinder 153 to rotate around the axial direction of the driven shaft 3 and the driving shaft 4 respectively, so as to close and open the first pressing wheel 11 and the second pressing wheel 12.
