Digital Quenching Technology of Leaf Spring

Abstract

The invention discloses a digital quenching process of a leaf spring, and belongs to the technical field of a heat treatment and quenching process of a leaf spring. According to the present invention, the whole set of the quenching and cooling process is matched with the special equipment, the quenching cooling temperature is controlled by a digital terminal, the cooling curve close to the design process is achieved, the ideal material structure and the performance can be obtained, and the quality of the finished product leaf spring is substantially improved; the organic polymer water-soluble quenching liquid is used to replace the rapid oil or diesel oil to quench so as to save the rapid oil or the diesel oil, such that the production cost is reduced, and the production environment and the natural resources are protected; the quenching equipment achieves the whole-process automation during the operation implementation so as to reduce the labor consumption, and the workers only require the remote operation without close contact of the quenching environment so as to provide the high safety and health coefficient; and the production cost is reduced with the automatic equipment, and the process is suitable for small samples and can further achieve mass production.

Description

technical field [0001] The invention belongs to the technical field of heat treatment and quenching process of leaf springs, and in particular relates to a digital quenching process of leaf springs. Background technique [0002] At present, the quenching process of the leaf spring cannot be digitally monitored, and the cooling curve after quenching cannot be precisely controlled, so that it is in line with the expected design process cooling curve, and ultimately the expected material structure and performance cannot be obtained. The various performances of the obtained leaf springs are different from the design expectations. [0003] In view of this, the applicant designed a complete set of quenching and cooling process, with special equipment, the quenching cooling temperature is controlled through the digital terminal, to achieve a cooling curve close to the design process, to obtain ideal material structure and performance, and greatly improve the leaf spring finished p...

[0002] At present, the quenching process of the leaf spring cannot be digitally monitored, and the cooling curve after quenching cannot be precisely controlled, so that it is in line with the expected design process cooling curve, and ultimately the expected material structure and performance cannot be obtained. There is a certain gap between the performance of the obtained leaf spring and the design expectation
