Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, and more specifically to a forging heat treatment cooling device. Background Art

[0002] Forging is a machining process. A forging is an object where metal is subjected to pressure to form a desired shape or suitable compression force through plastic deformation. This force is typically achieved by using a hammer or a press. The forging process builds a fine grain structure and improves the physical properties of the metal. In the forging production process, the forging needs to be cooled after the heat treatment operation is completed.

[0003] In the existing technology, such as the document with publication number CN220265766U, a front axle forging heat treatment cooling device is specifically disclosed. When the device in the document is cooled again, when the high-temperature forging is in contact with the coolant after heat treatment, a large amount of fog will quickly appear on the surface of the forging due to the rapid change in temperature. This fog not only greatly reduces the clarity of the working environment, but also seriously hinders the staff's observation and judgment of the operation process, thereby affecting the smooth progress of subsequent work. For this reason, we propose a forging heat treatment cooling device. Utility Model Content

DETAILED DESCRIPTION

The outer wall of the mounting seat 1 is fixedly connected to a base 14, and a motor 15 is fixedly connected to the bottom of the base 14. The output end of the motor 15 is fixedly connected to the bidirectional threaded rod 13, and the motor 15 drives the bidirectional threaded rod 13 to rotate, so that the two second hinge seats 12 move along the bidirectional threaded rod 13 respectively, and the two second hinge seats 12 approach each other at the same time. The two second hinge seats 12 push the first hinge seat 10 to move upward through the support arm 11, so that the cooling box 9 moves upward until the top of the cooling box 9 contacts the bottom of the top cover 5 to form a sealed space, thereby preventing the mist generated during cooling from spreading outward, affecting the clarity of the working environment and hindering the operation of the staff, thereby ensuring the smooth progress of subsequent work.

[0022] like Figure 2 As shown, a guide groove 7 is provided at the top of the inner wall of the top cover 5, and the depth of the guide groove 7 decreases from the middle to both sides. During cooling, the generated mist water will adhere to the inner wall of the top cover 5 and move along the inner wall of the top cover 5 and the guide groove 7 toward the top of the liquid accumulation frame 16, so that the mist water can be quickly collected.

[0023] like Figure 2 and Figure 3As shown, the inner wall of the top cover 5 is fixedly connected to a liquid accumulation frame 16, the outer wall of the liquid accumulation frame 16 is provided with a drainage hole 17, the inner wall of the drainage hole 17 is provided with a card slot 18, the inner wall of the card slot 18 is fixedly connected to a sealing ring 25, the outer wall of the liquid accumulation frame 16 is fixedly connected to a fixed plate 19, the inner wall of the fixed plate 19 is slidably connected to a connecting rod 20, the bottom of the connecting rod 20 is fixedly connected to a baffle 23, a groove 26 is provided at the bottom of the top cover 5, a spring 22 is sleeved on the circumferential outer wall of the connecting rod 20, and two limit strips 21 are fixedly connected to the circumferential outer wall of the connecting rod 20, the two limit strips 21 respectively penetrate the fixed plate 19 and are slidably connected thereto, and the top of the connecting rod 20 penetrates It passes through the drainage hole 17 and extends above it. A sealing plug 24 is fixedly connected to the top of the connecting rod 20. The outer wall of the sealing plug 24 is in friction contact with the sealing ring 25. One end of the spring 22 is fixedly connected to the fixed plate 19, and the other end of the spring 22 is fixedly connected to the baffle 23. When the next forging is cooled, the cooling box 9 moves upward to squeeze the baffle 23. The baffle 23 moves to the inside of the groove 26, which can improve the sealing between the cooling box 9 and the top cover 5. At this time, the spring 22 is compressed, and the sealing plug 24 moves to above the drainage hole 17, so that the mist water collected in the liquid accumulation frame 16 can be discharged to the inside of the cooling box 9 through the drainage hole 17.

[0024] Working principle: cooling water is injected into the cooling box 9, and the forgings are conveyed through the two first roller conveyors 3. When the forgings move to the second roller conveyor 6, the motor 15 drives the bidirectional threaded rod 13 to rotate, so that the two second hinge seats 12 move along the bidirectional threaded rod 13 respectively, and at the same time, the two second hinge seats 12 approach each other, and the two second hinge seats 12 push the first hinge seat 10 upward through the support arm 11, so that the cooling box 9 moves upward until the top of the cooling box 9 contacts the bottom of the top cover 5 to form a sealed space. At this time, the forgings on the second roller conveyor 6 are immersed in the cooling water, so that the forgings are quickly cooled;

[0025] During cooling, the generated mist water will adhere to the inner wall of the top cover 5 and deviate toward the top of the liquid accumulation frame 16 along the inner wall of the top cover 5 and the guide groove 7, so that the mist water can be quickly collected;

[0026] When cooling the next forging, the cooling box 9 moves upward to squeeze the baffle 23, and the baffle 23 moves to the inside of the groove 26, which can improve the sealing performance between the cooling box 9 and the top cover 5. At this time, the spring 22 is compressed, and the sealing plug 24 moves to the top of the drainage hole 17, so that the mist water collected in the liquid accumulation frame 16 can be discharged into the cooling box 9 through the drainage hole 17;

[0027] After cooling, the motor 15 drives the bidirectional threaded rod 13 to rotate in the opposite direction, so that the cooling box 9 moves downward. At this time, the cooling box 9 is freed from the extrusion of the baffle 23. Under the elastic force of the spring 22, the sealing plug 24 moves downward and slides into the sealing ring 25 to seal the drainage hole 17. The second roller conveyor 6 conveys the forging to the first roller conveyor 3 on the other side of the mounting seat 1.

[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this.
