The two-piece automobile hub includes aluminum spokes and steel rims. The aluminum spokes are provided with arc-shaped cavities along the periphery of the spokes. There are iron inserts in the arc-shaped cavities. The iron inserts protrude from the arc cavity. The steel ring is welded to the iron inserts. Above, the iron insert is embedded into the arc-shaped cavity through a low-pressure mold. The iron insert is U-shaped and the cross-section is L-shaped. The arc-shaped part has an arc-shaped cavity. There are positioning holes. The low-pressure mold includes an upper mold and a lower mold. The upper mold is provided with a detachable positioning rod, and the upper mold groove is provided with upper and lower positioning rods. Iron, the positioning rod enters the groove on the upper die through the positioning hole on the iron insert from bottom to top. Limited by the welding performance of aluminum and steel, the steel rim can be welded on the iron insert after adding the iron insert. The steel rim has the advantages of greater strength and longer service life; and the design of the aluminum spoke center plate makes the weight less Lighter, can reduce fuel consumption, welded rim size can be changed according to customer requirements, and the products are more diversified.
The material of the lower mold is mold steel. There is a positioning hole for the positioning rod on the lower mold. The positioning rod can be detachably installed in the positioning hole of the positioning rod. Everyone solves the problem. Tags: car hub.
