The traditional quenching basket is mainly in a net frame-shaped structure, so that quenching liquid can quickly enter the quenching basket to be contacted with a high-temperature workpiece during quenching. However, such a quenching basket is difficult to be applied to the heat treatment of tubular workpieces, and the main reasons thereof include: (1) The tubular workpieces are generally longer but have smaller diameters, and when the tubular workpieces are loaded in the quenching basket, the phenomenon that the ends of the workpieces are exposed out of the quenching basket is easy to occur, so that the workpieces are blocked in the quenching basket, and the subsequent removal of the workpieces is not facilitated. (2) When the tubular workpiece is heated to a high temperature, the strength is obviously reduced, a large amount of piled workpieces can cause the situation that part of the lower workpiece is bent and deformed due to the gravity of the upper workpiece, the deformation is further strengthened and kept to a room temperature state after quenching, and the deformed tubular workpiece is difficult to recover in a correction mode due to the high hardness of the quenched workpiece, so that a defective product is formed.
