Description

Technical Field

[0001] The present invention belongs to the technical field of metal carburizing processing, and specifically refers to a heat treatment tooling for carburizing and quenching. Background Art

[0002] Carburizing is an important heat treatment process aimed at increasing the hardness and wear resistance of steel workpieces by increasing the carbon content on the surface layer, while maintaining the toughness and strength of the core. During this process, the workpiece is placed in a carbon-rich medium, and carbon atoms penetrate into the surface layer of the workpiece at high temperature. After carburizing, the workpiece is further quenched to form a gradient tissue structure with a high-hardness surface layer and a low-hardness core to meet different mechanical property requirements.

[0003] However, traditional carburizing furnaces have significant deficiencies when processing workpieces. Due to the uneven distribution of the atmosphere in the carburizing furnace, there are differences in the carburized layer depth and carbon concentration at different parts of the workpiece, namely the so-called "carburized layer difference". This uneven carburizing not only affects the overall performance of the workpiece but may also cause local failure during subsequent use of the workpiece. Summary of the Invention

[0017] (2) The setting of the workpiece pretreatment mechanism can direct the carbon flow and improve the carburizing efficiency in the area of cylindrical workpieces.

[0018] (3) The setting of the atomized carburizing mechanism. After the liquid carburizing agent is atomized, its surface area is greatly increased, and the contact opportunity with the workpiece is increased, thereby improving the carburizing speed.

[0019] (4) The setting of the atomized carburizing mechanism helps to reduce production costs by reducing the waste of conductive paste and improving the utilization rate.

[0020] (5) The setting of the atomized carburizing mechanism. The atomized carburizing agent can be more evenly distributed in the heating chamber, reducing the risk of uneven carburizing and ensuring that each part of the workpiece can obtain the required carburized layer.

[0021] (6) The setting of the atomized carburizing mechanism. The use of the atomized carburizing agent reduces the waste of the carburizing agent and improves the utilization rate of the carburizing agent.

[0022] (7) By replacing the air in the carburizing chamber with argon, the oxidation reaction between the workpiece and oxygen in the air during the carburizing process can be effectively avoided, thereby ensuring the carburizing quality.

[0023] (8) The air contains moisture, oxygen and other impurities, which may have an adverse effect on the carburizing process. By replacing the air with argon, the interference of these impurities on the carburizing process can be reduced, thereby improving the purity and quality of carburizing.

[0024] (9) The inert property of argon enables the carburizing process to be carried out in a more stable atmosphere, which helps to improve the carburizing efficiency. Description of the Drawings

The output end of the first motor 18 rotates to drive the first bevel gear 19 to rotate. The rotation of the first bevel gear 19 drives the second bevel gear 20 to rotate. The rotation of the second bevel gear 20 drives the drive tube 21 to rotate.

At the same time, the output end of the first motor 18 rotates to drive the first bevel gear 19 to rotate. The rotation of the first bevel gear 19 drives the second bevel gear 20 to rotate.

After heating is completed, the output end of the first cylinder 12 moves, the sealing plate 11 moves, the output end of the second cylinder 16 moves to drive the lifting block 17 to move downward. The downward movement of the lifting block 17 drives the turntable 37 to move downward.
