Description

Technical Field

[0001] This utility model relates to the field of mold steel technology, specifically to a rapid cooling heat treatment device for mold steel. Background Technology

[0002] Mold steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. The quality of the mold directly affects the quality of the pressure processing technology, the precision and output of the products, and the production cost. In addition to reasonable structural design and processing precision, the quality and service life of the mold are mainly affected by the mold material and heat treatment. Heat treatment refers to a metal heat working process in which materials are heated, held at a certain temperature and cooled in a solid state to obtain the desired structure and properties.

[0003] Authorization announcement number CN207347616U discloses a spray-cooling heat treatment device for mold steel, which includes: a first conveyor frame, a second conveyor frame, a base, a rotating shaft, a reducer, a first annular water pipe, and a second annular water pipe. The rotating shaft is vertically mounted on the base, and a turntable is mounted on the rotating shaft. The first annular water pipe is located above the turntable, and the second annular water pipe is located below the turntable. Several downward-pointing first nozzles are arranged at the bottom of the first annular water pipe, and several upward-pointing second nozzles are arranged at the top of the second annular water pipe. This spray-cooling heat treatment device for mold steel simultaneously sprays the upper and lower surfaces of the mold steel plate through the first and second nozzles to avoid cracking. After the turntable rotates to deliver the mold steel plate to the end of the second conveyor frame, it pauses and uses hooks to pull the mold steel plate onto the second conveyor frame for continued conveying.

[0004] In the above technical solution, the upper and lower surfaces of the mold steel plate are sprayed simultaneously by the first nozzle and the second nozzle to avoid cracking. However, during the spraying process, the mold steel is above the turntable, and the second nozzle located below cannot spray the mold steel completely. Furthermore, the coolant generated by the spraying falls directly into the outside environment, which can easily affect the working environment. Utility Model Content

[0013] This utility model provides a rapid cooling heat treatment device for mold steel, which has the following beneficial effects:

[0014] (1) This utility model uses a waterproof electric push rod to fix the mold steel between the first turntable and the second turntable by turning on the waterproof electric push rod. The drive motor is turned on and the mold steel is slowly rotated. At this time, the water pump is turned on and the spray head is used to cool the rotating mold steel evenly.
