Technical Field
[0001] This utility model relates to the field of gas quenching furnace technology, and in particular to a gas quenching furnace with good heat treatment effect. Background Technology
[0002] A gas quenching furnace with good heat treatment effect mainly involves the application of a vacuum environment, the need for rapid cooling, and the challenge of uniform heating. Heat treatment in a vacuum environment can effectively prevent the metal from reacting with oxygen in the air at high temperatures, thus preventing oxidation and decarburization. This is crucial for maintaining the purity and performance of metal materials. The vacuum environment also reduces surface contamination of the workpiece, improving the surface quality after heat treatment. This is especially important for workpieces requiring high precision and high surface quality. Rapid cooling allows the metal to quickly pass through the austenite transformation zone during quenching, forming hardened structures such as martensite, thereby increasing the material's hardness and strength. Compared to traditional oil or water quenching, gas quenching furnaces use gas as the cooling medium, enabling more uniform cooling of the workpiece and reducing thermal stress and deformation caused by large temperature gradients. To achieve uniform heating, gas quenching furnaces need to be equipped with a precise temperature control system. By monitoring and adjusting the furnace temperature in real time, it is ensured that all parts of the workpiece are heated uniformly, avoiding localized overheating or underheating. The airflow design inside the gas quenching furnace is also key to achieving uniform heating. By rationally arranging nozzles and air ducts, high-pressure gas can be evenly blown onto all surfaces of the workpiece, thereby achieving rapid and uniform cooling.
[0003] In the metal processing, heat treatment is one of the important means to improve the mechanical properties of materials. Traditional quenching methods include oil quenching and water quenching, but these methods have problems such as uneven cooling rate and easy deformation and cracking. Therefore, we propose a gas quenching furnace with good heat treatment effect to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a gas quenching furnace with good heat treatment effect, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A gas quenching furnace with good heat treatment effect includes: a gas quenching furnace body and a movable block. A planetary gear is rotatably mounted on one side of the movable block, and two insert plates are fixedly mounted on one side of the planetary gear. Both insert plates are slidably mounted inside the gas quenching furnace body. A bevel gear one is rotatably mounted inside the movable block, and a bevel gear five meshes with the bottom end of the bevel gear one. A connecting rod is fixedly mounted on the bottom end of the bevel gear five, and a bevel gear three is fixedly mounted on the bottom end of the connecting rod. A bevel gear two is rotatably mounted inside the movable block, and the bevel gear three meshes with the bevel gear two. A fixed gear is fixedly mounted on one side of the bevel gear two, and the fixed gear meshes with the planetary gear. An air cooling pipe is fixedly mounted inside the gas quenching furnace body, and an air pump is fixedly mounted on one side of the air cooling pipe. A heating device is fixedly mounted inside the gas quenching furnace body, and a vacuum pump is fixedly mounted on one side of the gas quenching furnace body. A rotation adjustment assembly is provided inside the movable block.
[0007] Preferably, the rotation adjustment assembly includes: a fixed rod and a bevel gear four. The fixed rod is fixedly installed on one side of the movable block, the bevel gear four is rotatably installed inside the fixed rod, a round rod is fixedly installed on one side of the bevel gear four, an electric push rod is fixedly installed inside the fixed rod, and a fixed plate is fixedly installed on both the output end of the electric push rod and one side of the fixed rod. Two transmission wheels are rotatably installed on one side of one of the fixed plates, one of which is fixedly connected to the round rod. Clamping blocks are rotatably installed on the sides of the two fixed plates that are close to each other, and one of the clamping blocks is fixedly connected to the transmission wheel.
[0008] Preferably, two limiting rings are sleeved on the outer side of the gas quenching furnace body, the gas quenching furnace body is rotatably installed in the two limiting rings, a support leg is fixedly installed on each of the two limiting rings, a fixing block is integrally formed at the bottom end of the two limiting rings, and a connecting block is fixedly installed at the bottom end of the moving block.
[0009] Preferably, a second motor is fixedly installed on one side of the fixing block, a threaded rod is fixedly installed on the output end of the second motor, and a threaded block is fixedly installed on one side of the connecting block, with the threaded block threadedly connected to the threaded rod.
[0010] Preferably, two T-slider blocks are fixedly installed on one side of the connecting block, and a sliding T-groove matching the two T-slider blocks is opened on the fixed block, and a sliding groove matching the threaded block is opened inside the fixed block.
[0011] Preferably, a T-shaped ring is fixedly installed on one side of the planetary gear, a rotating ring groove matching the T-shaped ring is opened on one side of the moving block, and an arc slot matching the two insert plates is opened on the main body of the gas quenching furnace.
[0012] Preferably, the movable block has a rotating groove that matches the first bevel gear and the connecting rod, and the fixed rod has a rotating groove that matches the fourth bevel gear.
[0013] In this utility model, a gas quenching furnace with good heat treatment effect is described. By activating a fixed block fixedly installed on one side of a fixed block, a second motor drives a threaded rod to rotate, thereby controlling the movement of a threaded block connected to the threaded rod. This causes the threaded block to move a connecting block and two T-slider blocks, which in turn move a moving block. The moving block then moves a planetary gear and two insert plates, allowing the insert plates to move out of the gas quenching furnace body. The material to be processed is then placed between two clamping blocks. An electric push rod is activated, causing a fixed plate fixedly installed at its output end to move, which in turn causes the clamping blocks to clamp the material. Subsequently, the second motor drives the threaded rod to rotate in the opposite direction, moving the threaded block. Throughout this process, both insert plates are slidably installed inside the gas quenching furnace body, preventing them from detaching. Furthermore, the planetary gear and the gas quenching furnace body have good sealing properties, facilitating processing. The connecting block moves the moving block into the gas quenching furnace body. A vacuum pump is then activated to create a vacuum environment inside the gas quenching furnace body. Finally, the heating device is activated for heating.
[0014] In this utility model, the gas quenching furnace with good heat treatment effect is activated by starting a motor fixedly installed on one side of the moving block. The motor drives a bevel gear fixedly installed at its output end to rotate, causing bevel gears four and five, which mesh with each other at their bottom ends, to rotate. Bevel gear four drives a round rod to rotate, which in turn drives a transmission wheel to rotate, which in turn drives a transmission belt to rotate, causing another transmission wheel to rotate and thus rotating the clamping block for heating. This provides uniform heating to reach the required temperature. Simultaneously, bevel gear five drives a connecting rod fixedly installed at its bottom to rotate, which in turn drives bevel gear three... The rotation causes bevel gear three to drive bevel gear two, which in turn drives a fixed gear, which in turn drives a planetary gear. The planetary gear, through two insert plates, drives the main body of the gas quenching furnace to rotate, further enhancing the heating. After completion, the air pump is started, which transmits high-pressure gas to the air cooling pipe. The high-pressure gas is then ejected from the air cooling pipe and quickly enters the furnace chamber to rapidly cool the heated workpiece. During this process, motor one continues to drive bevel gear one to rotate, which in turn causes the main body of the gas quenching furnace to drive the air cooling pipe and the transmission wheel to drive the clamping block to continue rotating, thus completing the quenching process more effectively and comprehensively.
[0015] This utility model has a reasonable structural design. Through the cooperation of multiple structures, it can rotate while heating and cooling, making the heating and cooling more uniform and achieving better heating. It can achieve efficient and uniform heat treatment effect, and significantly improve the hardness and strength of metal materials. Attached Figure Description

[0024] In this embodiment, two limiting rings 4 are sleeved on the outside of the gas quenching furnace body 1. The gas quenching furnace body 1 is rotatably installed in the two limiting rings 4. Support legs 5 are fixedly installed on both limiting rings 4. Fixed blocks 6 are integrally formed at the bottom of the two limiting rings 4. Connecting blocks 7 are fixedly installed at the bottom of the moving block 3 to realize the movement of the moving block and increase stability.
[0025] In this embodiment, a second motor 9 is fixedly installed on one side of the fixed block 6, and a threaded rod 14 is fixedly installed on the output end of the second motor 9. A threaded block 32 is fixedly installed on one side of the connecting block 7. The threaded block 32 is threadedly connected to the threaded rod 14 to better control its sliding.

Finally, the device fixed to one side of the moving block 3 is activated. Motor 12 drives the bevel gear 16, which is fixedly mounted at its output end, to rotate. This causes the bevel gears 23 and 29, which mesh with each other on one side, to rotate. Bevel gear 23 drives the round rod 24 to rotate, which in turn drives the transmission wheel 26 to rotate, which in turn drives the transmission belt 28.

The planetary gear 17 then drives the main body of the gas quenching furnace 1 to rotate through the two insert plates 12, further enhancing the heating. After completion, the air pump 8 is started, which transmits high-pressure gas to the air cooling pipe 13. The high-pressure gas is then ejected from the air cooling pipe 13, allowing it to quickly enter the furnace chamber and rapidly cool the heated workpiece. During this process, the motor 2 continues to drive the bevel gear 16 to rotate, which in turn causes the main body of the gas quenching furnace 1 to drive the air cooling pipe 13 and the transmission wheel 26 to drive the clamping block 30 to continue rotating, thus completing the quenching process more effectively and comprehensively.
