The invention belongs to the technical field of metal material heat treatment, and particularly relates to a quenching device for a high-speed steel heat treatment technology. Comprising a perforated base plate, perforated four walls and tool lifting hooks, the perforated base plate and the perforated four walls are fixed into a cube, and the lifting hooks are arranged on the radial axis and connected with the tops of the four walls. The specific furnace charging operation of the device comprises the following steps: orderly and densely placing a first layer of samples at the bottom of the tool; after the bottom of the tool is fully paved, a stainless steel gasket is inserted above the tool, and then an upper-layer sample is placed; the sample to be subjected to heat treatment is put into a heat treatment furnace, and heat treatment work is started; and after the sample is quenched and tempered for three times, naturally cooling to room temperature, and taking out the sample. The method solves the problems of
