Double-layer efficient air-blast quenching device and quenching method

Abstract

The invention discloses a double-layer efficient air-blast quenching device and a quenching method, and belongs to the technical field of heat treatment, the double-layer efficient air-blast quenching device comprises an air inlet channel, a quenching chamber, a charging basket, a conveying mechanism, a drainage chamber and an air outlet channel, and the quenching chamber is internally provided with a first station and a second station; the bottom area of the first station and the bottom area of the second station are both larger than the bottom area of the charging basket, the height of the first station and the height of the second station are both larger than two times of the height of the charging basket, and lifting splitting mechanisms are arranged on the two sides of the first station and the two sides of the second station. The two charging baskets are in a stacked state when entering the air-blast quenching chamber, splitting air-blast quenching is carried out in the quenching chamber through the lifting splitting mechanisms of the two stations, the charging baskets are stacked in the quenching chamber after quenching is completed, and the charging baskets are still in a double-layer stacked state when leaving the quenching chamber; the requirement of simultaneous air-blast quenching production of a large number of workpieces can be met; the heat treatment production line is high in productivity and small in occupied space.

Description

technical field [0001] The invention belongs to the technical field of heat treatment, and in particular relates to a double-layer high-efficiency air-cooled quenching device and a quenching method. Background technique [0002] As a key technology in the heat treatment process, air-cooled quenching has the advantages of small deformation, small residual stress, good stability of the workpiece after treatment, and no rebound in geometric dimensions; therefore, it is widely used in aluminum alloy thin-walled parts, engine cylinder heads and other structures with complex shapes The heat treatment of the parts has the advantages that other quenching methods cannot replace. [0003] However, due to the limitation of the traditional single-layer air-cooled quenching technology, only single-layer and single-basket workpieces can be processed at a time. In order to ensure the quenching effect, there is a cooling air gap between the workpieces, so the loading capacity of a single ba...
