Piston automatic quenching device and method based on incomplete solution treatment technology

Abstract

The invention discloses a piston automatic quenching device based on an incomplete solution treatment technology. The piston automatic quenching device comprises a quenching water tank, wherein a lifting mechanism is arranged outside the quenching water tank; a material receiving plate bracket is arranged along the vertical direction in the quenching water tank; a material receiving plate supportis arranged along the horizontal direction at the lower end of the material receiving plate bracket; the material receiving plate support is connected with a material receiving plate; the lifting mechanism is connected with the material receiving plate bracket; the piston automatic quenching device also comprises a material receiving plate tilting device for driving the material receiving plate totilt for material discharge; the piston automatic quenching device further comprises a material discharge device. The device can work independently or in combination, realizes automation and programcontrol of the quenching process, and can guarantee the quenching quality and process stability and reduce the labor intensity of workers.

Description

technical field [0001] The invention relates to a piston production device, in particular to an automatic quenching device for piston processing. Background technique [0002] The heat treatment of aluminum alloy piston is quite critical to the improvement of its physical properties, especially quenching (also known as solution treatment), which directly affects its tensile strength, corrosion resistance and cutting performance. The industry generally adopts two methods, one is complete solution treatment, that is, after the blanks after removing the pouring riser are packed in a box, the temperature is raised to 510°C in a resistance furnace, and after holding for 3 hours, it is quickly quenched and cooled in water. The other is the incomplete solution treatment process, that is, the piston blank that has just been cast is directly placed in water, and quenched with the remaining heat. This method has low energy consumption and low investment, and is used in the manufacture...

AI Technical Summary

Problems solved by technology

In actual production, due to the influence of workers' operating habits and skills, it often happens that the piston is not put in and taken out in time, and the cooling time is too long, which affects the temperature of the quenching medium water, resulting in unstable heat treatment quality.

Especially with the implementation of pouring machinery automation, it is becoming more and more difficult to match the manual control and operation of this link with the automatic pouring system
