A spray quenching device for multiple parts

Abstract

The invention relates to a fog quenching device for multiple parts, which comprises a fog system, a support system and a rotation system, wherein the fog system comprises a left fog board and a right fog board; the left fog board and right fog board are bilateral symmetry; the support system is used for supporting and suspending strip parts in need of fog quenching, and comprises a central shaft; the front and back ends of the central shaft are respectively provided with a bracket; the rotation system an adjustable cylinder; the cylinder shaft of the adjustable cylinder is connected with a base board; the left side of the base board is provided with a motor, and the right side of the base board is provided with a bearing carrier supporting frame; the upper end of the bearing carrier supporting frame is provided with a rolling shaft; and the left end of the rolling shaft is fixed with a chain wheel, and the right end of the rolling shaft is fixed with a half connector. The cambered board is beneficial to increasing the wrapping angle of the part in need of quenching and implementing sufficient and uniform fog quenching on the parts; and the rotation system can be utilized to flexibly control the rotation and stop of the support system, thereby flexibly controlling the positions of the parts in the support system.

Description

technical field [0001] The invention relates to the technical field of quenching heat treatment equipment, in particular to a spray quenching device for multiple parts. Background technique [0002] At present, the commonly used quenching media mainly include water, gas and oil. In single-medium quenching, water has the largest cooling capacity and is suitable for thick-walled parts, but it is easy to cause deformation and cracking of parts. At the same time, water temperature also has a great influence on cooling characteristics, which is difficult to control; gas quenching is too slow to cool, so it can only be used for quenching. Materials with good permeability; a large amount of smoke will be produced during oil quenching, polluting the environment, which is not conducive to energy saving and production cost reduction, and quenching oil is only used for workpieces with good hardenability, small wall thickness, complex shape, and requiring quenching deformation Small ar...
