Description

Technical Field

[0001] The utility model belongs to the technical field of quenching processing equipment and relates to a forging quenching processing device. Background Art

[0002] Quenching refers to the metal heat treatment process of heating a metal workpiece to a certain temperature and then immersing it in a cooling medium for rapid cooling. The purpose of quenching is to transform austenite in the metal into martensite or bainite, and then cooperate with tempering at different temperatures to greatly improve the stiffness, hardness, wear resistance, fatigue strength, and toughness of the metal, so as to meet the different usage requirements of various mechanical parts and tools. The existing forging quenching devices generally adopt immersion quenching. This method easily causes the heated coolant to always be in contact with the forging, affecting the quenching effect. At the same time, after quenching is completed, impurities will appear on the surface of the forging, and manual impurity removal is required. The manual labor intensity is high and the impurity removal is cumbersome. Therefore, there is an urgent need to design a forging quenching processing device that can overcome the above defects.

[0003] In order to overcome the deficiencies of the prior art, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a forging heat treatment processing device [Application No.: 202221823756.2], which includes a quenching pool. Support blocks are arranged at the top of both sides of the quenching pool. A fixed shaft is arranged between the two support blocks. A baffle is rotatably sleeved on the fixed shaft. Easy-to-adjust abutting components are arranged on both sides of the quenching pool. A support frame is arranged on the side of the quenching pool. A driving winding roller is arranged on the support frame. A lifting rope is wound on the driving winding roller. One end of the lifting rope is provided with a fixed component with an anti-overlapping function. Summary of the Utility Model
