Description

Technical Field

[0001] This utility model relates to the field of cooling technology in machining, and in particular to a cooling device for machining. Background Technology

[0002] Machining refers to the process of altering the shape, dimensions, or properties of a workpiece using mechanical equipment. Based on the processing method, it can be divided into cutting and pressure processing. The main reasons for requiring workpiece cooling during machining include ensuring machining accuracy, extending equipment life, improving work efficiency, and complying with safety regulations. An existing machining cooling device (publication number: CN222037781U) works by activating a first electric slide to move a sliding block laterally mounted on the outer side of a guide column. During this movement, the sliding block moves a mounting frame and top plate mounted vertically on its top, which in turn moves laterally, thus moving a nozzle mounted on the output end of a second electric slide to cool the top of the machining table. However, relying solely on the nozzle for cooling means the cooling medium directly contacts the high-temperature workpiece on the machining table, which can cause the workpiece surface to cool rapidly, leading to deformation and cracking. Furthermore, the heat exchange area of ​​the single spray method is limited, resulting in low cooling efficiency, which is insufficient to meet the cooling requirements of high-load, large-area machining scenarios. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling device for machining.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cooling device for machining includes a protective cover, a placement platform, and a movable frame. An air spray pipe is fixed to the upper end of the placement platform, and a fan is installed on the rear side of the placement platform by fasteners. An air inlet pipe is fixed between the fan and the air spray pipe. A filter cartridge is provided below the fan, and the filter cartridge is connected to the placement platform by a water pumping pipe. A cooling cylinder is fixedly installed on the top of the movable frame. A jacketed cavity is opened inside the cooling cylinder, and an atomizing head is fixedly installed in the central area of ​​the cooling cylinder.

[0005] As a further embodiment of this utility model, a water collection trough is provided inside the placement platform, and a wire mesh frame is embedded at the upper end of the water collection trough.

[0006] As a further embodiment of this utility model, a filter element is embedded inside the filter cartridge, and a return pipe is fixed to the end of the filter cartridge away from the water pumping pipe.

[0007] As a further embodiment of this utility model, a water pump is installed on the return pipe, and a water inlet pipe is fixed at the top of the return pipe. The other end of the water inlet pipe passes through the cooling cylinder and is fixedly connected to the atomizing head.

[0008] As a further embodiment of this utility model, an air inlet pipe is fixed on the fan, and a thin flexible tube is fixed to the other end of the air inlet pipe. The interlayer cavity is connected to the air inlet pipe through the thin flexible tube.

[0009] As a further embodiment of this utility model, a valve is fixed on the air inlet pipe, and an electric slide rail is installed on the upper end of the placement platform by fasteners.

[0010] As a further embodiment of this utility model, the movable frame slides on the electric slide rail, and a valve is fixed on the second air inlet pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects: During workpiece processing, the airflow generated by the fan first enters the semi-enclosed air spray pipe through the air inlet pipe 2, forming a uniform airflow to pre-cool the workpiece and reduce its initial temperature to avoid sudden cooling impact. Then, the airflow is divided into two paths: one path enters the jacket cavity of the cooling cylinder to form a ring-shaped enveloping airflow, and the other path continues to provide auxiliary cooling to the workpiece through the air spray pipe. At the same time, the atomizing head atomizes the cooling medium into fine droplets under high pressure. The ring-shaped airflow in the jacket cavity precisely carries the droplets and diffuses them in a cone shape. With the help of the electric slide rail driving the cooling cylinder to move horizontally, the air-mist mixture evenly covers the surface of the workpiece. This increases the heat exchange area and avoids the droplets directly impacting the workpiece, thereby reducing the risk of workpiece deformation and cracking and improving the cooling efficiency of the workpiece during machining.

[0017] Reference Figures 1-5 A cooling device for machining includes a protective cover 1, a placement platform 2, and a movable frame 3. An air spray pipe 202 is fixed to the upper end of the placement platform 2. A fan 6 is installed on the rear side of the placement platform 2 by fasteners. An air inlet pipe 603 is fixed between the fan 6 and the air spray pipe 202. A filter cartridge 4 is provided below the fan 6. The filter cartridge 4 is connected to the placement platform 2 by a water pumping pipe 401. A cooling cylinder 301 is fixedly installed on the top of the movable frame 3. A double-layer cavity 302 is opened in the cooling cylinder 301. An atomizing head 303 is fixedly installed in the central area of ​​the cooling cylinder 301.

[0018] When fan 6 operates, it generates airflow. At this time, valve 2 604 opens, and the airflow is entirely delivered to the spray pipe 202 through the air inlet pipe 2 603. The uniform airflow sprayed from the spray pipe 202 pre-cools the workpiece on the placement platform 2, reducing the initial temperature of the workpiece. Then, valve 1 602 is opened, causing the airflow from fan 6 to split into two paths. One path flows through the thin hose 305 into the jacket cavity 302 of the cooling cylinder 301 to form an annular airflow. The other path continues to provide auxiliary cooling to the workpiece through the spray pipe 202. At the same time, the water pump 404 is started. The cooling medium recovered in the water collection tank 203 is drawn into the filter cartridge 4 through the water pumping pipe 401. After impurities are filtered by the filter element 402 in the filter cartridge 4, it is transported to the atomizing head 303 through the return pipe 403 and the water inlet pipe 304. The atomizing head 303 atomizes the cooling medium into fine droplets under high pressure. Combined with the annular airflow in the jacket cavity 302, the droplets diffuse in a cone shape. Finally, the electric slide rail 5 drives the moving frame 3 to move the cooling cylinder 301 horizontally, so that the air-mist mixture evenly covers the surface of the workpiece, thereby achieving precise cooling.

[0019] In this embodiment, a water collection tank 203 is provided inside the placement platform 2, and a wire mesh frame 201 is embedded at the upper end of the water collection tank 203.

[0020] Impurities in the cooling medium in the water collection tank 203 are filtered by the filter element 402 inside the filter cartridge 4, preventing impurities from clogging the atomizing head 303 and the water inlet pipe 304, and ensuring the smooth circulation of the cooling medium.

[0021] In this embodiment, a filter element 402 is embedded inside the filter cartridge 4, and a return pipe 403 is fixed at the end of the filter cartridge 4 away from the water pumping pipe 401.

[0022] The electric slide rail 5 can drive the moving frame 3 to move the cooling cylinder 301 horizontally, so that the airflow in the sandwich cavity 302 carries the mist droplets formed by the atomizing head 303 to evenly cover the workpiece, ensuring the comprehensiveness of precise cooling.

[0023] In this embodiment, a water pump 404 is installed on the return pipe 403, and a water inlet pipe 304 is fixed at the top end of the return pipe 403. The other end of the water inlet pipe 304 passes through the cooling cylinder 301 and is fixedly connected to the atomizing head 303.

[0024] The electric slide rail model 5 can be selected from HIWIN's EG15 series.

[0025] In this embodiment, an air inlet pipe 601 is fixed on the fan 6, and a thin flexible tube 305 is fixed at the other end of the air inlet pipe 601. The interlayer cavity 302 is connected to the air inlet pipe 601 through the thin flexible tube 305.

[0026] During the cooling process, the used cooling medium is filtered through the mesh frame 201 on the placement platform 2 to remove large iron filings, and then flows back into the water collection tank 203 for the next cycle of use.

[0027] In this embodiment, a valve 602 is fixed on the air inlet pipe 601, and an electric slide rail 5 is installed on the upper end of the placement platform 2 by fasteners.

[0028] The airflow from the fan 6, delivered by the thin flexible tube 305, is received through the interlayer cavity 302. This forms an annular airflow that precisely carries the atomizing head 303's sprayed droplets into a cone shape, helping to evenly cover the workpiece with the air-mist mixture and achieve precise cooling.

[0029] In this embodiment, the movable frame 3 slides on the electric slide rail 5, and the second valve 604 is fixed on the second air inlet pipe 603.

[0030] The air jet pipe 202 has nozzles that are evenly spaced and tilted downwards, which can make the airflow spray out evenly to cover the workpiece to achieve pre-cooling and auxiliary cooling.

[0031] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: During the machining process, the fan 6 is first started, and the fan 6 generates airflow. At this time, valve 2 604 is opened, and the airflow is completely delivered to the spray pipe 202 through the air inlet pipe 2 603. The uniform airflow sprayed from the spray pipe 202 pre-cools the workpiece on the placement table 2, reducing the initial temperature of the workpiece. Then, valve 1 602 is opened, so that the airflow from the fan 6 is divided into two paths. One path is introduced into the jacket cavity 302 of the cooling cylinder 301 through the thin hose 305 to form an annular airflow. The other path continues to provide auxiliary cooling for the workpiece through the spray pipe 202, while simultaneously drawing... The water pump 404 starts, drawing the cooling medium recovered in the water collection tank 203 into the filter cartridge 4 through the pumping pipe 401. After impurities are filtered by the filter element 402 in the filter cartridge 4, it is transported to the atomizing head 303 through the return pipe 403 and the inlet pipe 304. The atomizing head 303 atomizes the cooling medium into fine droplets under high pressure. Combined with the annular airflow in the jacket cavity 302, the droplets diffuse in a cone shape. Finally, the electric slide rail 5 is activated to drive the moving frame 3 to move the cooling cylinder 301 horizontally, so that the air-mist mixture evenly covers the surface of the workpiece. This not only achieves efficient cooling of the workpiece but also realizes the recycling of the cooling medium. At the same time, the pre-cooling and air-mist synergy reduces the risk of workpiece deformation and cracking.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
