Isolation type leaf spring steel sheet preparing device and method

Abstract

The invention relates to an isolation type leaf spring steel sheet preparing device and method. The isolation type leaf spring steel sheet preparing device comprises an upper cooling box, a lower cooling box, a controller and the like. A check valve I is connected with a water inlet connector I of the upper cooling box, so water backflow in the upper cooling box is prevented; a water outlet connector I is connected with a check valve III, so water backflow in a water outlet is prevented; a temperature sensor I is placed in the upper cooling box; a check valve II is connected with a water inletconnector II of the lower cooling box, so water backflow in the lower cooling box is prevented; a water outlet connector IV is connected with a check valve IV, so water backflow in the water outlet is prevented; a temperature sensor II is placed in the lower cooling box; the controller controls the opening degree of a proportional valve and the water supply speed of a circulating pump through temperature signals detected by the temperature sensor, so the temperature feedback regulation of the upper cooling box and the lower cooling box is realized, and the aim of controlling the temperature of a leaf spring steel sheet is realized. The method solves the problems of quenching deformation and breakage of spring steel strips in a traditional spring steel strip preparing process and overcomesthe defects of severe pollution and high cost in a traditional technique.

Description

technical field [0001] The invention relates to an isolated spring steel bar preparation device and method, belonging to the field of spring steel bar manufacturing and processing. Background technique [0002] Spring steel is the raw material for preparing elastic components such as spring leaf springs. Because springs are used under shock, vibration or long-term alternating stress, spring steel is required to have high tensile strength, elastic limit, and high fatigue strength. In terms of technology, spring steel is required to have certain hardenability, not easy to decarburize, and good surface quality. The preparation technology of spring steel strips is the key factor that limits the performance of leaf springs. [0003] At present, the commonly used spring steel bar preparation processes mainly include hot-rolled spring steel bar, shearing, variable cross-section, ear rolling, forming heat treatment, shot blasting, assembly and other processes. In the forming heat tr...
