Embodiment

[0026] This embodiment is based on the liquid die forging process in CN106345984B with the publication number, the difference is that the extrusion of the spokes is added in step E, including the following steps:

[0027] A. Alloy composition optimization;

[0028] B. Melting: Melt the A357 aluminum ingot in a fast melting furnace and keep it warm;

[0029] C. Deslagging and degassing: Degas and deslag the melt obtained in step A with a high-efficiency refining agent in the furnace to make the melt clean and free of impurities; remove impurities and gases inside the aluminum alloy melt, which can further improve the purity of the alloy. Improve the metallographic structure of the alloy, eliminate internal defects such as shrinkage cavities, porosity, pores, and cracks in the product, and improve the surface quality of the workpiece at the same time;

[0030] D. Liquid die forging: the wheel hub blank 11 is obtained, the wheel hub blank 11 includes the rim and the spokes, and ...

Abstract

The invention belongs to the technical field of vehicle hubs, and relates to a spoke performance improving method applied to a liquid die forging hub product, the hub is formed by integrating a rim and a spoke, and the spoke is extruded after liquid die forging and before heat treatment. The problem that the mechanical performance of the spoke part of an existing liquid die forging hub product islower than that of a flange and a rim part is solved, and the overall performance of the hub is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle wheels, and relates to a method for improving the performance of spokes applied to liquid die forging wheel products. Background technique [0002] The wheel hub is one of the most important safety parts on the car. The wheel hub bears the pressure of the car and the load, is affected by the dynamic torque of the vehicle when starting and braking, and also withstands the turning of the car during driving, uneven roads, and road surfaces. Irregular alternating force generated by dynamic loads from different directions such as obstacle impact. The quality and reliability of the wheel not only affect the safety of the vehicle and the personnel and materials on the vehicle, but also affect the stability, maneuverability, comfort and other performance of the vehicle during driving. This requires the wheel hub to have good dynamic balance, high fatigue strength, With good rigidity and elasticity, high ...
