Digital quenching equipment for leaf springs

Abstract

The invention discloses a digital quenching device for a steel plate spring, and belongs to the field of heat treatment quenching and cooling devices for steel plate springs. The quenching and cooling temperature of the complete dedicated quenching and cooling device, designed by an applicant, is controlled by a digital terminal to obtain a cooling curve approaching to the cooling curve in the design technology, an ideal material structure is obtained, high performance is achieved, and the finished product quality of the steel plate spring is improved greatly. The digital quenching device is suitable for heat treatment of small-batch and multiple-variety steel plate springs, the production speed is high, the device structure is compact, and energy loss is low. An intelligent temperature control system is adopted to strictly control the heating quality, and the temperature uniformity of a quenching bath and the surface decarburization control index of the product are remarkably improved.

Description

technical field [0001] The invention belongs to the field of heat treatment quenching equipment for leaf springs, and in particular relates to digital 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 furnace is suitable for large-scale production of a single variety in large quantities. When organizing production of small batches, multi-variety, and trial-produced products, it will take a lot of time to change molds, slow down the production cycle, and significantly reduce energy consumption. growth and many...

[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 furnace is suitable for large-scale production of a single variety in large quantities. When organizing production of small batches, multi-variety, and trial-produced products, it will take a lot of time to change molds, slow down the production cycle, and significantly reduce energy consumption. growth and many other disadvantages,
