Device of improving quenching and cooling

Abstract

The invention provides a device of improving quenching and cooling. The device of improving quenching and cooling is designed for solving the technical problems that when a part is quenched and cooled, the organization difference is large due to the fact that cooling is not uniform, the part deforms or is cracked due to the fact that cooling is too fast, and the organization of the part is not qualified due to the fact that cooling is too slow. The device of improving quenching and cooling comprises a quenching tank and a power output device, wherein the power output device is connected with the quenching tank. The quenching tank at least comprises a flow distribution facility. The quenching tank comprises a bottom, an open top and a side wall, wherein the side wall is connected with the bottom and the top. The flow distribution facility is connected with the side wall. An oil flow distribution device, namely a flow guide seam, is added in a stirring flow guide opening formed in the bottom of an existing facility, the flow of quenching liquid in various regions is controlled according to the seam to achieve the purpose that cooling of the part in the quenching process is more uniform and more effective, and therefore the quality of the part is improved.

Description

technical field [0001] The invention relates to the technical field of metal heat treatment design, in particular to a device for improving quenching and cooling. Background technique [0002] In the production of box-type multi-purpose furnace, when parts are quenched and cooled, uneven cooling leads to large differences in structure, which has always been a problem that plagues the industry. Too fast cooling will cause deformation or cracking of parts, and too slow cooling will lead to unqualified parts. Especially in the box-type multi-purpose furnace, the phenomenon is more obvious, because the parts are used, quenching from top to bottom, the oil circulation uses the agitator deflector to divert the flow into the quenching tank, resulting in different coolant volumes in each section after quenching , resulting in a difference in the cooling effect of the parts. By adding an oil diversion device (divergence slot) at the bottom of the original equipment and at the stirri...
