Technical Field

[0001] The invention relates to the technical field of metal material processing, and in particular to a quenching heat treatment device for metal material processing. Background Art

[0002] Quenching and cooling is a basic process of metal heat treatment, which means heating metal materials and components to a certain temperature and then cooling them in a predetermined manner and rate to obtain the expected structure and performance. In the process of quenching and cooling metal materials, quenching equipment is usually required.

[0003] At present, the traditional quenching method is often to directly place the heated metal material in the coolant for quenching and cooling. During the quenching process, the coolant around the metal material will form a stable steam film wrapped around the surface of the metal material due to rapid vaporization.

[0017] 1. The present invention has a reasonable structure. When the servo motor is started, the support shaft is driven to rotate. The rotation of the support shaft drives the placement net box to move up and down through the winding wheel and the wire rope, and then the placement net box can be lowered into the quenching pool to quench the metal material. In this process, the rotation of the support shaft drives the eccentric rotating column to rotate in a circle through the first pulley, the first belt, the driving shaft, and the driving disc. The eccentric rotating column rotates in a circle through the second slide groove to drive the reciprocating swing rod to swing back and forth with the horizontal shaft as the fulcrum, and then the placement net box can be driven to swing back and forth through the first slide groove and the connecting slide rod, so as to avoid the surface of the metal material being wrapped by the steam film and causing the cooling speed to slow down, and the cooling rate of the metal material can be better controlled, thereby affecting its organization and performance, so as to achieve the expected hardness, strength and other mechanical properties, optimize the quenching process, and improve the quality and performance of the metal material;

[0018] 2. In the present invention, when the supporting shaft rotates, the second pulley and the second belt will drive the connecting shaft to rotate synchronously. The connecting shaft will drive the stirring impeller to rotate together through the active bevel gear, the driven bevel gear and the vertical shaft, thereby stirring the coolant in the quenching pool, so that the coolant is in a flowing state and can be more evenly covered on the surface of the metal material, effectively reducing the occurrence of local overheating or uneven cooling, and improving the quenching heat treatment quality of the metal material;

[0019] 3. In the present invention, when the control pull block is pulled, the fixed plug rod is driven to move out of the fixed plug hole, and the installation sleeve is loosened.

[0020] 4. In the present invention, through the coordinated arrangement of the condensation hood, the meandering collecting trough and the reflux pipe, when steam is generated during the quenching process, the steam will rise and contact the condensation hood. At this time, the steam will be cooled and become droplets, and then flow back to the quenching pool through the inner wall of the condensation hood, the meandering collecting trough and the reflux pipe for recycling, thereby saving resources.
