Description

Technical Field

[0001] This application relates to the field of workpiece cooling technology, and in particular to a cooling structure for workpieces. Background Technology

[0002] Currently, workpiece cooling methods are selected based on material, process requirements, and efficiency, mainly including: natural cooling (air cooling, low cost but slow), forced air cooling (fan acceleration, suitable for medium-sized needs), water cooling (spraying or immersion, fast but may cause deformation), oil cooling (uniform cooling with quenching oil, used for precision heat treatment), refrigerant cooling (refrigeration unit or liquid nitrogen, extremely low temperature and controllable), and inert gas, spray cooling, or phase change cooling (such as dry ice) for special scenarios. When choosing a method, a balance must be struck between cooling rate, workpiece characteristics (such as oxidation prevention and crack prevention), and cost.

[0003] Traditional workpiece cooling methods typically employ water cooling. The process involves filling a specially designed cooling tank or water bath with cooling water, then using specialized clamps to hold the workpiece and completely immerse it in the water for rapid cooling. This immersion water cooling method is common in heat treatment and machining, utilizing the high thermal conductivity of water to achieve rapid workpiece cooling.

[0004] Regarding the aforementioned technologies, the inventors believe that during operation, when a high-temperature workpiece is immersed in a cooling water tank, a large amount of high-temperature steam will be generated instantly. This steam may not only reduce visibility in the working environment, but also scald the operators. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cooling structure for workpieces, which solves the technical problem that when a high-temperature workpiece is immersed in a cooling water tank during operation, a large amount of high-temperature steam will be generated instantly. This steam may not only reduce the visibility of the working environment, but also burn the operator.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A cooling structure for a workpiece includes: a frame for supporting the cooling structure; a cooling tank mounted on the frame and filled with cooling water; grippers mounted on the frame for clamping the workpiece; a drive assembly mounted on the frame for driving the grippers to slide on the frame; and an extraction assembly mounted on the frame for extracting water mist generated in the cooling tank.

[0008] Furthermore, the drive assembly includes a clamping cylinder, and two grippers are spaced apart on the clamping cylinder. The clamping cylinder drives the grippers to move toward one side closer to or further away from each other.

[0009] Furthermore, a rotary motor is provided on the frame, the rotary motor is slidably mounted on the frame, and the clamping cylinder is mounted on the output shaft of the rotary motor.

[0010] Furthermore, the frame is provided with a slide rail and a sliding cylinder, the slide rail is provided with a slide plate, the sliding cylinder drives the slide plate to slide on the slide rail, and the rotary motor is mounted on the slide plate.

[0011] Furthermore, the air extraction assembly includes an air extraction hood, which is installed on the cooling tank and has an air extraction port facing towards the side close to the cooling tank. The air extraction hood also has an air outlet connected to an external pipeline.

[0012] Furthermore, the frame is provided with an air blowing pipe, one end of which forms an air blowing port, and the air blowing port faces the side close to the cooling tank.

[0013] Furthermore, a drain pipe is provided at the bottom of the cooling tank, with one end of the drain pipe connected to the cooling tank and the other end extending away from the cooling tank.

[0014] In summary, this application includes at least one of the following beneficial technical effects of a cooling structure for a workpiece:

[0015] 1. When in use, add cooling water to the cooling tank, then drive the clamping jaws to clamp the workpiece. After that, the clamping jaws immerse the workpiece in the cooling tank. During the cooling process, the air extraction component extracts air from the top of the cooling tank, thereby reducing the impact of high-temperature steam generated when the high-temperature workpiece is immersed in the cooling water tank on the visibility of the working environment and preventing the high-temperature steam from scalding the operator.

[0016] 2. By using clamping cylinders and rotating motors, as well as slide rails and sliding cylinders, the ease of movement of the grippers on the machine frame is improved;

[0017] 3. The cooling effect of the workpiece is improved by setting up an exhaust hood and an air blowing pipe. Attached Figure Description

[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses a cooling structure for a workpiece.

[0025] Reference Figure 1 A cooling structure for workpieces includes a frame 1 with a cooling tank 2 filled with cooling water. The frame 1 is equipped with grippers 3 and a drive assembly 4, which drives the grippers 3 to place the workpiece into the cooling tank 2. An extraction assembly 5 is also provided on the frame 1 to remove water vapor generated during the workpiece cooling process, reducing the impact of water vapor on the operator.

[0026] Reference Figure 2 The cooling tank 2 is mounted on the frame 1. Cooling water is added to the cooling tank 2 during use. Furthermore, a drain pipe 21 is installed at the bottom of the cooling tank 2. One end of the drain pipe 21 is connected to the bottom of the cooling tank 2, and the other end extends away from the cooling tank 2. When the cooling water in the cooling tank 2 is used up, the drain pipe 21 at the bottom of the cooling tank 2 can be opened directly, eliminating the need to lift the cooling tank 2 and improving the convenience of replacing the cooling water in the cooling tank 2.

[0027] The extraction assembly 5 includes an extraction hood 51, which is mounted on the cooling tank 2. An extraction port 52 is formed on the extraction hood 51, facing towards the side closest to the cooling tank 2. An outlet 53 is formed on the side of the extraction hood 51 opposite to the extraction port 52, and the outlet 53 is connected to an external pipeline. In use, an external extraction device extracts air from the extraction hood 51 through a pipeline. At this time, a negative pressure is formed at the extraction port 52 of the extraction hood 51. When the workpiece is cooled in the cooling tank 2 and water vapor is generated, the water vapor moves towards the side closest to the extraction port 52, enters the extraction hood 51, and is then discharged towards the outlet 53. As the extraction hood 51 continuously extracts air from the cooling tank 2, the impact of water vapor generated during the workpiece cooling process on the operator can be reduced.

[0028] Reference Figure 3 The drive assembly 4 includes a slide rail 41, which is mounted on one side of the cooling tank 2. A sliding cylinder 42 is mounted on the slide rail 41. Furthermore, a slide plate 43 is mounted on the slide rail 41, and in use, the sliding cylinder 42 drives the slide plate 43 to slide on the slide rail 41. Additionally, a rotary motor 44 is mounted on the slide plate 43, and the axis of the rotary motor 44 is perpendicular to the sliding direction of the slide rail 41. Furthermore, a clamping cylinder 45 is mounted on one end of the output shaft of the rotary motor 44, perpendicular to the rotary motor 44 and mounted on its output shaft. Two grippers 3 are arranged opposite each other on the clamping cylinder 45, which controls the grippers 3 to move closer to or further away from each other.

[0029] In use, the sliding cylinder 42 drives the slide plate 43 to slide from one side of the cooling tank 2 to the other side. At the same time, the clamping cylinder 45 drives the gripper 3 to clamp the workpiece. Then, the rotating motor 44 drives the clamping cylinder 45 to rotate 180 degrees. During the rotation of the rotating motor 44, the workpiece on the clamping cylinder 45 is immersed in the cooling tank 2. When the clamping cylinder 45 slides to the other side of the cooling tank 2, the workpiece is also removed from the cooling tank 2.

[0030] Since the workpiece moves within the cooling tank 2 during immersion, the cooling effect of the workpiece can be greatly improved, preventing local temperature rise within the cooling tank 2 from affecting the cooling of the workpiece.

[0031] After the workpiece enters the cooling tank 2, coolant will adhere to its surface. Therefore, an air blowing pipe 11 is installed on the frame 1, and an air blowing port 12 is formed at one end of the air blowing pipe 11. In use, the air blowing pipe 11 blows air onto the workpiece through the air blowing port 12 to blow off the coolant adhering to the workpiece and reduce the amount of coolant adhering to the workpiece surface.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
