Embodiment 1

[0015] The aluminum wheel hub first passes through the camera system. The camera system takes pictures of the shape of the wheel rim and then transmits it to the X-ray machine control system. The X-ray machine retrieves the corresponding program and uses X-rays to irradiate different parts of the wheel rim to find defects inside the aluminum wheel hub. ; The X-ray machine judges that it is OK to continue to stay, and it is NG to discard it. The aluminum wheel hub passes through the X-ray machine, then the riser machine and then reaches the heat treatment. The heat treatment is divided into solid solution, quenching and aging; the temperature of the solid solution stage is set at 544°C, the heating time is 25 minutes, the holding time is 110 minutes, and then the wheel hub is maintained at 544 The temperature of ℃ enters the quenching, the time is 20S, and soaks in the quenching medium of 85 ℃ for 5 minutes. The quenching medium is 15 parts of potassium nitrate, 20 parts of sod...

Abstract

The invention belongs to the field of wheel hub machining, and particularly relates to a wheel hub heat treatment speed-up technology. The heat treatment method comprises three stages, namely a solid solution stage, a quenching stage and an aging stage. The flow of the wheel hub heat treatment speed-up technology comprises the steps that a casted aluminum wheel hub passes through an X-ray machine and a dead head punching machine, and then the aluminum wheel hub is subjected to heat treatment, wherein the heat treatment comprises the solid solution stage, the quenching stage and the aging stage; the temperature for the solid solution stage is set between 540 DEG C to 550 DEG C, the heating-up time ranges from 25 minutes to 28 minutes, the heat-preserving time ranges from 110 minutes to 115 minutes, the wheel hub enters the quenching stage while maintaining the temperature of the solid solution stage; the quenching time is below 20 seconds, the wheel hub is soaked into a quenching medium for 5 minutes at a temperature ranging from 80 DEG C to 90 DEG C, and the wheel hub enters the aging stage; the temperature of the aging stage ranges from 155 DEG C to 165 DEG C, and the heat-preserving time is 60 minutes.

Description

technical field [0001] The invention belongs to the field of wheel hub processing, and in particular relates to a wheel hub heat treatment speed-increasing process. Background technique [0002] Wheel hub is a high-tech, high value-added auto parts developed in recent years. It is a new economic growth point and development direction in the automotive field, especially the successful development of the third-generation wheel produced by DELPffi, the world's largest auto parts supplier. Localization of the wheel has become a top priority, and heat treatment is a key process in the manufacture of wheel units. ; Because of the complex surface shape of the parts, the heat treatment process is difficult and demanding, and has become a key process in the development of this project. Aluminum wheels are constantly being recognized for their advantages of light weight, energy saving, good heat dissipation, aesthetics, corrosion resistance, and good processability. The use of alumin...
