The invention relates to a quenching device, in particular to a quench machining tool with a rapid mold changing device and a thread opening limiting device. The quench machining tool is formed by additionally arranging the thread opening limiting device and replacing a changing device of an upper mold with the rapid changing device adopting a connection rod mechanism driven by an air cylinder for locking and unlocking on the basis of an existing mold pressing quench machining tool, wherein the thread opening limiting device is used for limiting deformation of the thread opening position of a workpiece during quenching. According to the technical scheme, on the one hand, deformation of the thread opening and a roller path of the workpiece is effectively controlled during quenching and reduced, coaxiality is improved, the grinding amount of subsequent machining is effectively reduced, and the machining efficiency and percent of pass of the product are improved; and on the other hand, the changing time of the upper mold of the mold pressing quench machining tool is shortened. By means of the technical scheme, the quench machining tool has the advantages of being reasonable in structure, good in use effect and suitable for improvement of the existing mold pressing quench machining tool.
