Embodiment 1

[0016] A wheel hub casting molding process includes the following steps:

[0017] (1) Preparation of aluminum alloy melt: it is composed of the following substances by mass percentage: 1% magnesium, 1% silicon, 2% iron, 0.5% copper, 1% manganese, 2% nickel-chromium alloy , Additives 0.5%, the rest is aluminum;

[0018] (2) Melting: Add the aluminum alloy melt in step (1) to the melting furnace and adjust the temperature to 725°C. Use an electromagnetic stirrer to stir the melt for 10 minutes to make the temperature in the molten pool uniform. Add a refining agent to the aluminum alloy The melt is refined for 10 minutes, the surface scum is removed, the temperature is adjusted to 700 ℃, and the argon gas is used for degassing and refining for 10 minutes;

[0019] (3) Casting: Put the aluminum liquid slag in step (2) to stand for 20 minutes, first preheat the mold, the preheating temperature is 180 ℃, and then hydraulically insert the aluminum into the mold for casting, the casting te...

Abstract

The invention discloses a hub casting and forming technology and relates to the field of automobile spare part casting. The hub casting and forming technology comprises four technology steps of aluminium alloy melting stock preparation, melting, casting and cooling and forming. The process route is simple; the process conditions are easy to meet; the appearance of a casting which is cast has no casting flaw, no pore and no impurity; the internal tissue is compact; the quality of a hub can be ensured; the service life is prolonged; and the economical benefit is improved.

Description

Technical field [0001] The invention relates to the field of auto parts casting, in particular to a wheel hub casting molding process. Background technique [0002] In the 20th century, with the development of society, the demand for automobiles is increasing. The wheel hub is an important component of the automobile. The performance of the wheel hub is directly related to the performance of the entire automobile. However, in the existing technology, the automobile The wheel hub is prone to pores and inclusions during casting, resulting in poor quality of the wheel hub, low service life, and unable to meet production requirements. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a wheel hub casting molding process to solve the problems caused by the prior art that the automobile hub is prone to pores and inclusions during casting, resulting in poor quality of the hub, low service life, and failure to meet production requir...
