Description

Technical Field

[0001] The utility model relates to the technical field of dry cutting tools, in particular to a device for extending the service life of high-speed dry cutting tools. Background Art

[0002] Cutting fluids play a role in reducing cutting temperatures, breaking chips, and removing them during metal cutting. However, their use, storage, cleaning, and disposal are relatively cumbersome and costly. The harmful effects of cutting fluids on the environment and operator health have long been a concern, and their disposal costs are high. Adopting dry cutting can significantly reduce cutting fluid usage, thereby reducing costs and mitigating the impact on the environment and operators. However, cutting tools generate high temperatures during cutting. Without cutting fluid, cooling can only be achieved through air cooling. This air cooling method has the following drawbacks: high-speed airflow causes chips to fly in all directions, posing a safety hazard; and air cooling is inefficient. Improvements are needed, and therefore, we propose a device to extend the service life of high-speed dry cutting tools. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1, as Figure 1-3 As shown, the utility model provides a technical solution: a device for extending the service life of a high-speed dry cutting tool, comprising a liquid-cooled heat exchanger 2 attached to the surface of a tool 1, a spiral heat exchange tube 201 being provided inside the liquid-cooled heat exchanger 2, and an input end and an output end of the spiral heat exchange tube 201 being connected to a liquid inlet pipe 4 and a liquid return pipe 5, respectively, and both the liquid inlet pipe 4 and the liquid return pipe 5 are connected to a coolant pump assembly mechanism 7;

[0020] The coolant pump group mechanism 7 includes a coolant box 704 filled with coolant, a cooling fan 706 is provided on one side of the coolant box 704, a through-hole group 705 is provided on all four surfaces of the coolant box 704, a heat dissipation fin group 708 is fixedly provided on the outer wall surface of the coolant box 704, the top of the coolant box 704 is connected to the pump body 702 through a liquid extraction pipe, the output end of the pump body 702 is connected to the liquid inlet pipe 4 through the pipe A701, and the top of the coolant box 704 is connected to the pipe B703, and the pipe B703 is connected to the return pipe 5 through a joint.

[0021] In a specific embodiment of the present invention, the end of the tool 1 is fixed to the tool holder, and the area of ​​the tool 1 exposed outside the tool holder is used to install the liquid-cooled heat exchanger 2. The tool 1 and the liquid-cooled heat exchanger 2 can be installed in two ways: magnetic attraction and adhesive bonding. The magnetic attraction method is to set an iron sheet on the surface of the tool 1 and set a magnet on the contact surface of the liquid-cooled heat exchanger 2 and the tool 1; the adhesive method is to set an adhesive sheet on the contact surface of the liquid-cooled heat exchanger 2 and the tool 1. The adhesive sheet is a high-temperature resistant masking tape;

[0022] The liquid extraction pipe of the pump body 702 extends into the interior of the coolant tank 704 for extracting coolant. The pump body 702 and the air-cooling fan 706 are both powered by a power cord. When the pump body 702 and the air-cooling fan 706 are started, the air-cooling fan 706 cools the coolant tank 704 externally. At the same time, the through-hole group 705 cooperates with the airflow, which is conducive to accelerating the cooling of the coolant. The coolant passes through the liquid extraction pipe, the pump body 702, the tube body A701, the liquid inlet pipe 4, the spiral heat exchange tube 201, the liquid return pipe 5 and the tube body B703, and finally flows back to the interior of the coolant tank 704. The air-cooling fan 706 cooperates with the through-hole group 705 and the heat dissipation fin group 708 to cool the coolant after heat exchange.

[0023] In the preferred technical solution, a thermocouple sensor 3 is embedded in the contact end face of the liquid-cooled heat exchanger 2 and the tool 1. The thermocouple sensor 3 is electrically connected to the temperature display 707 through the data line 301. The thermocouple sensor 3 is attached to the tool and transmits data to the temperature display 707 through the data line. The temperature display 707 is used to process the electrical signal of the thermocouple sensor 3 and display the real-time temperature of the tool 1 through the digital display screen.

[0024] In the preferred technical solution, the data cable 301, the liquid inlet pipe 4 and the liquid return pipe 5 are all passed through the gooseneck tube 6. The gooseneck tube 6 is used to centrally store and organize the data cable 301, the liquid inlet pipe 4 and the liquid return pipe 5 to prevent the data cable 301, the liquid inlet pipe 4 and the liquid return pipe 5 from affecting the operation of the tool 1.

[0025] In the preferred technical solution, the heat dissipation fin group 708 is composed of a number of vertically parallel fins, the long side direction of the fins is parallel to the blowing direction of the air-cooling fan 706, and the heat dissipation fin group 708 increases the air-cooling contact area and improves the cooling efficiency.

[0026] In the preferred technical solution, the through hole group 705 is arranged above the heat dissipation fin group 708, and the coolant height inside the coolant box 704 is lower than the lowest height of the through hole group 705, thereby preventing the coolant from overflowing from the through hole group 705.

[0027] In the preferred technical solution, the diameter of the through holes of the through hole group 705 is set to 5 mm to reduce the amount of coolant flying out of the through hole group 705 during blowing.

[0028] Working principle: The liquid-cooled heat exchanger 2 is directly attached to the surface of the tool 1, and the coolant flows in the spiral heat exchange tube 201 inside the liquid-cooled heat exchanger 2, so that when the tool performs dry cutting, it can still be cooled efficiently. The coolant temperature after heat exchange is relatively high and flows back to the coolant tank 704. The air-cooling fan 706 is in the started state. The air-cooling fan 706 performs external cooling on the coolant tank 704. At the same time, the through-hole group 705 cooperates with the airflow to accelerate the cooling of the coolant.
