Description
Technical Field
[0001] This utility model relates to the field of quenching production line technology, specifically to an automated quenching production line for a large drop mandrel. Background Technology
[0002] The automated quenching production line for large-drop mandrels is an integrated application of modern industrial automation technology, optimized heat treatment processes, and intelligent control systems. This production line uses high-precision sensors to monitor key parameters such as temperature, speed, and cooling rate in real time. Combined with PLC and industrial computers, it achieves precise control of process parameters. It uses robotic arms and conveying devices to complete the automatic loading, unloading, positioning, and transfer of mandrels. It is also equipped with multi-medium quenching tanks and rapid cooling devices to meet the quenching requirements of different materials. Its core advantage lies in achieving high efficiency, stability, and consistency in the quenching process of large-drop mandrels, significantly improving product quality and production efficiency.
[0003] However, it still has some drawbacks, such as: the cooling water tank of the quenching production line lacks an active cooling device, which makes the temperature of the cooling liquid easily fluctuate due to environmental influences, affecting the uniformity of mandrel quenching. At the same time, conventional cooling methods rely on natural convection, which has low cooling efficiency.
[0004] To address the aforementioned issues, this application proposes an automated quenching production line for large-drop mandrels. Utility Model Content
[0005] The purpose of this invention is to provide an automated quenching production line for large drop mandrels, in order to solve the problem mentioned in the background art of the lack of active cooling devices in the cooling water tank of the quenching production line.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automated quenching production line for a large-drop mandrel, comprising a quenching production line body, a bottom load-bearing cabinet fixedly connected below the quenching production line body, a drop-type rapid cooling water tank fixedly connected to the right side of the bottom load-bearing cabinet, and an air refrigeration compressor device installed inside the bottom load-bearing cabinet. The drop-type rapid cooling water tank facilitates the supply of cold air to the cooling liquid inside the tank by installing a cold air injection pipe inside the tank and connecting it to the air refrigeration compressor device, ensuring that the internal cooling liquid remains in a refrigerated state, and rapidly cooling begins after the mandrel is quenched, thereby improving the cooling effect.
[0007] Preferably, the main body of the quenching production line and the bottom of the drop-type rapid cooling water tank are fixedly connected to an anti-slip base plate, and the anti-slip base plate is provided in multiple sets.
[0008] Preferably, the main body of the quenching production line is fixedly connected to both sides of the mandrel raw material conveying cylinder device, a cold air injection pipe is installed on one side of the inside of the drop-type rapid cooling water tank, a shielding frame is fixedly connected above the drop-type rapid cooling water tank, and an air intake is installed on the front top of the bottom load-bearing cabinet.
[0009] Preferably, the bottom load-bearing cabinet is equipped with an inspection door on the front, the quenching production line body is equipped with a quenching device inside, a control console is fixedly connected to the top of the quenching production line body, a main switch is installed on the right side of the front of the control console, a running indicator light is installed on the front of the control console, and a control button is installed on the left side of the front of the control console.
[0010] Preferably, an intake pipe is fixedly connected to the top of the air refrigeration compressor device, an air intake port is fixedly connected to one side of the intake pipe, and a mounting plate is fixedly connected to the rear end of the air refrigeration compressor device.
[0011] Preferably, the mounting plate is fixedly connected to the rear end of the bottom load-bearing cabinet. A cold air output pipe is fixedly connected to one side and below the air compressor unit. An anti-backflow U-shaped pipe is fixedly connected below the cold air output pipe, and a cold air injection pipe is fixedly connected below the anti-backflow U-shaped pipe. When using the drop-type rapid cooling water tank, when the quenched mandrel enters the tank, the air compressor unit inside the bottom load-bearing cabinet draws in air through the air intake. After compression and refrigeration, low-temperature cold air is formed. Because the horizontal position of the air compressor unit is higher than that of the drop-type rapid cooling water tank, liquid backflow into the air compressor unit can be prevented. Inside the compressor unit, cold air is continuously injected into the drop-type rapid cooling water tank through a cold air output pipe, an anti-backflow U-shaped pipe, and a cold air injection pipe. The anti-backflow U-shaped pipe, with its unique U-shaped structure, helps prevent liquid from flowing back into the air refrigeration compressor unit even if pressure fluctuations occur in the cooling liquid within the tank, ensuring safe operation of the equipment. The cold air directly contacts the cooling liquid in the drop-type rapid cooling water tank, achieving forced convection heat transfer. Simultaneously, the large drop design of the drop-type rapid cooling water tank ensures that the high-temperature workpiece is quickly immersed after falling, and combined with the dynamic agitation of the cold air, a uniform and efficient cooling environment is formed.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention features a drop-type rapid cooling water tank, which facilitates the installation of a cold air injection pipe inside the tank and connection to an air refrigeration compressor device.

Rapid cooling begins after the mandrel is quenched, thus improving the cooling effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] In this embodiment, as shown Figures 1-2 As shown, the main body 1 of the quenching production line and the drop-type rapid cooling water tank 4 are fixedly connected to an anti-slip base plate 7, and multiple sets of anti-slip base plates 7 are provided.

The control button 33 is installed on the left side of the front of the control console 3.
[0021] In this embodiment, as shown Figures 3-4As shown, an intake pipe 51 is fixedly connected to the top of the air refrigeration compressor unit 5, and an air intake port 21 is fixedly connected to one side of the intake pipe 51. A mounting plate 52 is fixedly connected to the rear end of the air refrigeration compressor unit 5, and the mounting plate 52 is fixedly connected to the rear end of the bottom load-bearing cabinet 2. A cold air output pipe 53 is fixedly connected to one side and below the air refrigeration compressor unit 5. An anti-backflow U-shaped pipe 54 is fixedly connected below the cold air output pipe 53, and a cold air injection pipe 55 is fixedly connected below the anti-backflow U-shaped pipe 54. When using the drop-type rapid cooling water tank 4, when the quenched mandrel enters the drop-type rapid cooling water tank 4, the air refrigeration compressor unit 5 in the bottom load-bearing cabinet 2 draws in air through the air intake port 21, and after compression and refrigeration, forms low-temperature cold air. The refrigeration compressor unit 5 is positioned horizontally higher than the drop-type rapid cooling water tank 4, which prevents liquid from flowing back into the air refrigeration compressor unit 5. Cold air is continuously injected into the drop-type rapid cooling water tank 4 through the cold air output pipe 53, the anti-backflow U-shaped pipe 54, and the cold air injection pipe 55. The anti-backflow U-shaped pipe 54, with its unique U-shaped structure, helps to prevent liquid from flowing back into the air refrigeration compressor unit 5 even if the cooling liquid in the tank experiences pressure fluctuations, ensuring the safe operation of the equipment. The cold air and the cooling liquid in the drop-type rapid cooling water tank 4 come into direct contact to achieve forced convection heat exchange. At the same time, the large drop structure design of the drop-type rapid cooling water tank 4 allows the high-temperature workpiece to be quickly immersed after falling, which, combined with the dynamic stirring effect of the cold air, forms a uniform and efficient cooling environment.

The drop-type rapid cooling water tank 4 facilitates the supply of cold air to the cooling liquid in the tank by installing a cold air injection pipe 55 inside the tank and connecting it to the air refrigeration compressor device 5, ensuring that the internal cooling liquid remains in a refrigerated state, and starting rapid cooling after the mandrel is quenched, thereby improving the cooling effect.

This ensures the internal cooling liquid remains refrigerated, allowing for rapid cooling after mandrel quenching and improving the cooling effect. When using the drop-type rapid cooling water tank 4, as the quenched mandrel enters the tank, the air refrigeration compressor unit 5 inside the bottom load-bearing cabinet 2 draws in air through the air intake 21. After compression and refrigeration, low-temperature cold air is generated. Because the horizontal position of the air refrigeration compressor unit 5 is higher than that of the drop-type rapid cooling water tank 4... It can prevent liquid from flowing back into the air refrigeration compressor unit 5. The cold air is continuously injected into the drop-type rapid cooling water tank 4 through the cold air output pipe 53, the anti-backflow U-shaped pipe 54 and the cold air injection pipe 55.
