Description

Technical Field

[0001] The utility model relates to the technical field of steel material processing equipment, in particular to a heat treatment device for die steel. Background Art

[0002] Heat treatment refers to a metal heat processing process in which the material is heated, kept warm and cooled in solid state to obtain the expected structure and performance. Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing technologies, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but rather changes the microstructure inside the workpiece, or changes the chemical composition of the workpiece surface, to give or improve the performance of the workpiece.

[0003] In the prior art, such as a heat treatment device for mold steel in Chinese patent application number CN202121559859.8, it includes a heat treatment box. The rotation of the first screw can drive the electric heating tube to move up and down, thereby adjusting its heating position for the mold steel, and the rotation of the second screw can drive the height position of the support plate to change, thereby adjusting the position of the mold steel, and the two can cooperate with each other to adjust the mold steel to a suitable position for heating more reasonably, thereby realizing the heat treatment operation thereof, and having a good user experience. However, in the process of heat treatment, the heat treatment needs to repeatedly perform the heating and cooling process to fix its shape and prevent one-time heating from causing internal damage to the steel structure, but this device only achieves the heating process. When cooling, the staff needs to wear equipment to put the high-temperature mold steel into the coolant for cooling, and then put it into the heating box for heating. Repeating this process not only causes the staff to have trouble in carrying, which is not conducive to improving work efficiency, but also easily causes the staff to be injured due to high-temperature handling.

[0004] In the prior art, for example, Chinese patent CN 219385217 U discloses a heat treatment device for mold steel, which includes a machine body, a heating box and an upper heating plate. A telescopic rod is provided, which is automatically extended and retracted by a motor, and the telescopic rod is connected to a pallet for transporting the mold steel, so that the mold steel can automatically enter and exit the heating box during the heating process, thereby preventing the worker from being scalded due to frequent transport during the heating process. The benefit of automation means that the worker does not need to operate all the time, which effectively improves the work efficiency. However, the patent still has the following problems.

[0005] In the above-mentioned patent, although a shower device is provided to cool the mold steel, some coolant may remain on the mold steel after the coolant is sprayed on the mold steel. When the mold steel enters the heating box for heating again, the coolant on its surface may reduce the heating speed of the mold steel and may cause waste of coolant. Utility Model Content
