[0001] The utility model relates to the technical field of tool magazines, in particular to a heat dissipation device for tool magazines. Background Art

[0002] With the rise of CNC machine tools, simple rotary disc tool magazines began to appear. They had relatively small capacity and were usually used to store a few tools. Later, as the manufacturing industry's demand for efficient processing increased, tool magazines and automatic tool changing systems developed rapidly, and the capacity and tool changing speed gradually increased. Chain tool magazines and disc tool magazines gradually replaced rotary disc tool magazines, and the capacity increased from a few tools to dozens of tools.

[0026] like Figure 1 to Figure 2 As shown, a heat dissipation device for a tool magazine comprises:

[0027] A housing 1, the housing 1 is used to accommodate the tool and provide a heat dissipation channel, and is provided with a ventilation system 2 and a cooling circulation pipeline 3;

[0028] A ventilation system 2, the ventilation system 2 comprises a natural vent 21 and a forced ventilation fan 22, the natural vent 21 and the forced ventilation fan 22 form a cooling airflow around the tool;

[0029] The cooling circulation pipeline 3 is arranged inside the housing 1 and is used for circulating coolant around the tool.

[0030] The tool is placed in the housing 1, and a heat dissipation channel is provided on the housing 1, including a ventilation system 2 and a cooling circulation pipe 3. The natural vents 21 in the ventilation system 2 allow air to circulate freely to form a basic cooling airflow, while the forced ventilation fan 22 increases the airflow to ensure that the air circulates quickly around the tool. When the tool is running, the forced ventilation fan 22 introduces cold air from the inlet into the housing 1. The air flows through the tool and takes away the heat, ensuring that the temperature inside the housing 1 remains stable. At the same time, the cooling circulation pipe 3 circulates coolant inside the housing 1 to further take away the heat generated by the tool.

[0031] Through the coordination of natural ventilation and forced ventilation, as well as the assistance of circulating coolant, the tool can always maintain a suitable working temperature during operation. The entire device ensures the stability and control of the tool's operating temperature and always maintains an efficient cooling effect.

[0032] In this embodiment, a plurality of natural ventilation openings 21 are provided and are evenly distributed at different positions on the housing 1 .

[0033] The natural vents 21 evenly distributed on the housing 1 effectively optimize the ventilation and cooling efficiency of the entire tool magazine. The natural vents 21 can ensure that air circulates evenly around the tool to form a continuous and stable cooling airflow. Even when the forced ventilation fan 22 is not working, air can still flow smoothly through the natural vents 21 to maintain air circulation inside the housing 1, avoid heat accumulation, ensure the stability and consistency of the tool temperature, and extend the tool life.

[0034] In this embodiment, the forced ventilation fan 22 includes an inlet fan 22A and an outlet fan 22B. The inlet fan 22A is used to introduce cold air into the interior of the housing 1 , and the outlet fan 22B is used to discharge hot air in the housing 1 .

[0035] The cold air brought by the inlet fan 22A can quickly reduce the temperature around the prop, while the outlet fan 22B discharges the hot air in time to prevent the internal temperature from rising, forming a cooling air flow cycle, so that the tool can maintain a suitable temperature during the processing, avoid overheating, increase the service life of the tool, and ensure that the air flow inside the shell 1 is always stable and effective.

[0036] In this embodiment, both the natural ventilation opening 21 and the forced ventilation fan 22 are provided with filter screens 23 .

[0037] Filters 23 are provided on both the natural ventilation opening 21 and the forced ventilation fan 22, which effectively block the entry of external dust and particulate matter, ensure the cleanliness of the air entering the shell 1, avoid the impact of impurities on the cutting tool, extend the service life of the ventilation system 2, reduce the maintenance frequency, and improve the efficiency and reliability of the overall heat dissipation device.

[0038] In this embodiment, the forced ventilation fan 22 has an adjustable wind speed function, and the cooling effect can be adjusted according to the ambient temperature and the heat of the tool.

[0039] By adjusting the wind speed, the ventilation system 2 can increase the airflow in a high temperature environment or during high load processing to quickly remove excess heat and prevent the tool from overheating. In addition, at lower temperatures or lighter processing loads, reducing the wind speed can reduce energy consumption, extend the service life of the fan, and ensure the overall efficiency and reliability of the heat dissipation device.

[0040] In this embodiment, the cooling circulation pipe 3 is made of a high thermal conductivity material, and the inner wall is coated with an anti-corrosion coating.

[0041] The cooling circulation pipe 3 is made of high thermal conductivity material, so that heat can be quickly transferred from the tool to the coolant, thereby improving the overall cooling efficiency. The inner wall of the cooling pipe is coated with an anti-corrosion coating, which effectively prevents the coolant from corroding the pipe, prolongs the service life of the cooling circulation pipe 3, and maintains its thermal conductivity. The combination of high thermal conductivity material and anti-corrosion coating ensures the long-term stability of the cooling effect and reduces the maintenance and replacement frequency of the cooling circulation pipe 3.

[0042] In this embodiment, a temperature sensor 24 is further provided in the ventilation system 2. The temperature sensor 24 is used to monitor the internal temperature of the tool magazine and trigger the forced ventilation fan 22 to start when the temperature exceeds a preset value.

[0043] The temperature sensor 24 provided in the ventilation system 2 can monitor the internal temperature of the housing 1 in real time. When the temperature exceeds the preset value, the temperature sensor 24 automatically triggers the forced ventilation fan 22 to start, quickly remove the excess heat, and ensure that the tool is always kept within the appropriate temperature range. The temperature sensor 24 is used to realize the intelligent control of the forced ventilation fan 22, ensuring that timely and effective cooling effects can be provided in high-load processing or high temperature environments to prevent the tool from overheating. Through the precise monitoring and timely adjustment of the temperature sensor 24, the tool can maintain high precision and stability during the processing process, extend the tool life, and improve cooling efficiency and reliability.

[0044] In this embodiment, the forced ventilation fan 22 is provided with a silencer 22C.

[0045] The silencer 22C can effectively reduce the noise generated by the ventilation system 2 during operation, making the operating environment of the entire tool magazine quieter and more comfortable, reducing the interference of high noise to operators, and ensuring that the ventilation system 2 maintains a low noise level when operating efficiently, thereby improving processing efficiency and meeting higher working environment requirements.

The above embodiments and the description are only for explaining the principle of the present invention.
