Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a vacuum quenching device for heat treatment. Background Art

[0002] Vacuum quenching technology is an advanced technology for heat treatment of metal materials. It changes the structure and properties of the workpiece by placing it in a vacuum furnace, heating it in an oxygen-free or low-oxygen atmosphere, and then rapidly cooling it. Vacuum quenching technology can effectively control the heating and cooling process of the workpiece, avoid oxidation and deterioration, and thus improve the hardness, strength and wear resistance of the material. When the vacuum quenching device is used for heat treatment quenching of metal materials, the metal materials are usually placed inside the vacuum quenching furnace used by the vacuum quenching device. Since the internal structure of the vacuum quenching furnace is usually fixed and the layout cannot be changed, when encountering metal materials of different sizes, such as smaller metal materials, it is easy to be unable to be effectively placed. In order to avoid the above problems, it is usually necessary to place it on a specific metal table. However, the lower surface of the metal material that needs vacuum quenching will be affected by the table, causing the contact surface to be heated but not as well as the upper surface, thereby affecting the use effect of the vacuum quenching device for heat treatment. At the same time, the vacuum quenching device for heat treatment cannot be applied to metal materials of different sizes, affecting the versatility of the vacuum quenching device for heat treatment, and indirectly affecting the use effect of the vacuum quenching device for heat treatment and the efficiency of vacuum quenching.

[0003] Therefore, it is necessary to develop a vacuum quenching device for heat treatment. Utility Model Content

According to the number of metal materials that need to be heat-treated and vacuum quenched on site, multiple sets of square columns are correspondingly installed, and the U-shaped frame is inserted into the inside of the square column by the telescopic column in a sliding manner, so that the U-shaped frame can pull the distance between the U-shaped frame and the metal material according to the size of the metal material, so that the metal material can be placed and supported by the U-shaped frame, and the screw rod B is set in the threaded hole on the U-shaped frame in a threaded connection manner. After the metal material is placed, the screw B is rotated to the pressure plate on the bottom end to clamp and fix the metal material. After the metal material is fixed, vacuum quenching can be performed. This avoids the situation where metal materials of different sizes cannot be effectively placed, and also avoids the situation where uneven heating occurs during the vacuum quenching process after the metal material is placed.
