Special Quenching Equipment for Leaf Springs

Abstract

The invention discloses a dedicated quenching device of a steel plate spring, and belongs to the field of heat treatment quenching cooling equipment of steel plate springs. According to a whole quenching and cooling dedicated device designed by an inventor, quenching cooling temperature is controlled through a numeric terminal, the cooling curve approaching to the design technology is achieved, the ideal material structure and the ideal performance can be obtained, and the finished product quality of the steel plate spring is greatly improved. The dedicated quenching device can be suitable for small-batch multispecies steel plate spring heat treatment, the production rhythm is rapid, the device is compact in rhythm, and energy consumption losses are small.

Description

technical field [0001] The invention belongs to the field of heat treatment quenching equipment for leaf springs, and in particular relates to special quenching equipment for leaf springs. Background technique [0002] At present, the quenching equipment 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. In addition, the existing step-by-step quenching heating furnace is suitable for large-scale production of a single variety in large batches. There will be many disadvantages in the production of small batches, multi-variety, and trial-produced products. Energy consumption losses increased significantly. [0003] In view of this, the applicant has designed a ...

[0002] At present, the quenching equipment 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

In addition, the existing step-by-step quenching heating furnace is suitable for large-scale production of a single variety in large batches. There will be many disadvantages in the production of small batches, multi-variety, and trial-produced products. Significant increase in energy consumption loss
