[0061] Working principle:

[0062] Structure and movement of the rolling rolls: The left main shaft and the right main shaft are respectively inclined at a certain angle to each other and rotate in the same direction around their own axis lines during operation. At the same time, the spiral grooves on the rolling rolls form a spiral pass in the deformation zone.

[0063] Rotation and advancement of the rolled piece: Relying on the frictional contact force between the rolling rolls and the aluminum rod, the rolling rolls drive the aluminum rod to rotate in the opposite direction and advance axially. In this process, under the action of the spiral pass, the aluminum rod continuously rotates and moves axially.

[0064] Deformation and forming of metal: As the aluminum rod rotates and advances, the metal gradually fills the spiral pass. Under the constraint of the spiral pass and the pressure of the rolls, the aluminum rod undergoes plastic deformation, its diameter is gradually compressed, and it extends axially, gradually forming a spherical shape. During the forming process, the connecting neck part between the spheres becomes thinner and thinner.

[0065] Separation of aluminum balls: After the aluminum rod is rolled into spherical shapes, in the finishing section, the spheres are further finished and separated from the rod, and finally the required aluminum balls are obtained.

[0066] Working process:

[0067] As shown in the figure, the aluminum rod enters the metal rod inlet on the guide plate seat from the feeding end. Under the spatial limitation of the upper guide plate, the lower guide plate, the left roll, and the right roll, the aluminum rod completes plastic deformation in a limited space, finally forms aluminum balls, and is discharged from the discharging end.
