Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and relates to a sawing cooling device, particularly a combined sawing cooling device for a CNC horizontal circular saw. Background Technology

[0002] Circular saws are an essential tool in machining, used to cut materials such as steel and wood. Circular saws can be categorized by the products they process: metal circular saws and woodworking circular saws. They are also classified by feeding method: vertical, horizontal, and scissor-type. Furthermore, they can be classified by control method: manual, semi-automatic, and fully automatic. Specialized material racks are available to meet various needs. Circular saws generate significant heat due to friction during cutting, which can affect the cutting process; therefore, they require a cooling system.

[0003] A search revealed a Chinese patent document disclosing a cooling device for a circular saw [Application No.: 202120474204.4; Publication No.: CN 216298169 U]. This cooling device for a circular saw includes a saw blade, a water storage tank, a water pump, two water pipes located on both sides of the saw blade, and two cooling mechanisms located on both sides of the saw blade. The water pump is housed within the water storage tank, with its input end located within the tank. The water pump has two output ends, each connected to one end of one of the two water pipes, and the other ends of the two water pipes are connected to the two cooling mechanisms. The water pump is used to supply water from the water storage tank to the cooling mechanisms through the water pipes. The beneficial effects of this invention are: it allows for simultaneous direct spraying of cutting fluid from both sides onto the cutting area, achieving complete cooling without requiring a large flow rate, thus reducing cutting fluid consumption. Simultaneous spraying from both sides also ensures more uniform cooling of the cutting fluid on both sides.

[0004] Although this patent reduces the consumption of cutting fluid and can achieve more uniform cooling of cutting fluid on both sides by spraying on both sides, it still has certain limitations in terms of heat dissipation through water alone. For example, the cutting fluid will vaporize in a high-temperature environment, creating air resistance and reducing heat exchange efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a combined sawing and cooling device for a CNC horizontal circular saw. The technical problem to be solved by this utility model is: how to achieve the combined use of air cooling and water cooling, break through the limitations of a single heat dissipation method, and achieve complementary advantages in terms of efficiency, stability, and energy consumption.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A combined sawing and cooling device for a CNC horizontal circular saw includes a circular saw protective cover and a cooling box. The circular saw protective cover is fixed with a cold water pipe and a cold air pipe. Multiple cold air nozzles are arranged and fixed inside the circular saw protective cover, all connected to the cold air pipes. Multiple cold water nozzles are also arranged and fixed inside the circular saw protective cover, all connected to the cold water pipes. A cold water tank is fixed on the cooling box. A cold air chamber is opened inside the cooling box, and heat sinks are fixed inside the cold air chamber. An air inlet pipe is fixed from inside the cold water tank, with one end exposed outside the cold water tank and the other end connected to the cold air chamber. An air pump is fixed on the cooling box, with its input end connected to the cold air chamber and its output end connected to the cold air pipe. A water pump is fixed on the cooling box, with its input end connected to the bottom of the cold water tank and its output end connected to the cold water pipe.

[0008] The working principle of this invention is as follows: cold water from a cold water tank is pumped into a cold water pipe via a water pump. The cold water pipe is then connected to a cold water nozzle to spray cold water. The cold water absorbs heat through vaporization, which lowers the temperature of the saw blade. This is a heat transfer cooling method. When the cold water comes into contact with the high-temperature saw blade, the water evaporates rapidly, absorbing a large amount of heat, thereby lowering the surface temperature of the saw blade. At the same time, a cold air is drawn in by an air pump and delivered to the cold air nozzle through a cold air pipe. The cold air nozzle blows onto the saw blade, further accelerating the heat dissipation process and improving the cooling effect.

[0009] The heat sink is hollow inside, and an infusion pump is fixed inside the cooling box. The infusion pump's input end is connected to a cold water tank, and its output end is connected to the heat sink.

[0010] With the above structure, the infusion pump can be used to draw cold water from the cold water tank and inject it into the heat sink, thereby improving the heat absorption effect of the heat sink. Furthermore, the infusion pump can maintain the heat dissipation effect of the heat sink by repeatedly drawing and injecting water into the heat sink.

[0011] An air filter element is fixed inside the air intake pipe.

[0012] With the above structure, the collected cold air can be filtered through the air filter element, reducing the amount of dust adhering to the saw blade, thereby reducing saw blade wear and improving cutting efficiency.

[0013] The cold water tank is fixed with a water inlet, which is connected to the cold water tank.

[0014] With the above structure, an external water supply pipe can be connected through the water inlet interface, allowing water to be delivered into the cold water tank to replenish the cold water and facilitate the continuous operation of the cooling process.

[0015] The heat sink is made of copper.

[0016] By adopting the above structure, the excellent thermal conductivity of copper can be used to improve the overall heat absorption and cooling effect and efficiency.

[0017] Compared with existing technologies, the combined sawing and cooling device of this CNC horizontal circular saw has the following advantages:

[0018] 1. A water pump draws cold water from the cold water tank into the cold water pipe, which is then connected to a cold water nozzle to spray cold water. The cold water absorbs heat through vaporization, which is a heat transfer cooling method. When the cold water comes into contact with the high-temperature saw blade, the water evaporates rapidly, absorbing a large amount of heat, thereby reducing the surface temperature of the saw blade.

[0019] 2. Simultaneously, cold air is drawn in by an air pump and delivered to the cold air nozzles through cold air pipes. The cold air nozzles blow the saw blade, which helps to accelerate the heat dissipation process of the saw blade and further improves the cooling effect. Attached Figure Description

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-4As shown, a combined sawing cooling device for a CNC horizontal circular saw includes a circular saw protective cover 1 and a cooling box 2. The circular saw protective cover 1 is fixed with a cold water pipe 3 and a cold air pipe 15. Multiple cold air nozzles 4 are arranged and fixed inside the circular saw protective cover 1, all of which are connected to the cold air pipes 15. Multiple cold water nozzles 5 are also arranged and fixed inside the circular saw protective cover 1, all of which are connected to the cold water pipes 3. A cold water tank 6 is fixed on the cooling box 2. The cooling box 2 has a cold air chamber 7, and a heat sink 8 is fixed inside the cold air chamber 7. An air inlet pipe 9 is fixed inside the cold water tank 6. One end of the air inlet pipe 9 is exposed outside the cold water tank 6, and the other end of the air inlet pipe 9 is connected to the cold air chamber 7. An air pump 10 is fixed on the cooling box 2. The input end of the air pump 10 is connected to the cold air chamber 7, and the output end of the air pump 10 is connected to the cold air pipe 15. A water pump 11 is fixed on the cooling box 2. The input end of the water pump 11 is connected to the bottom of the cold water tank 6, and the output end of the water pump 11 is connected to the cold water pipe 3.

[0027] The cold water in the cold water tank 6 can be pumped into the cold water pipe 3 by the water pump 11. The cold water pipe 3 is then connected to the cold water nozzle 5 to achieve cold water spraying. The cold water reduces the temperature of the saw blade by absorbing heat through vaporization, which is a heat transfer cooling method. When the cold water comes into contact with the high temperature saw blade, the water evaporates rapidly, absorbing a large amount of heat, thereby reducing the surface temperature of the saw blade. At the same time, the air pump 10 draws in cold air and delivers the cold air to the cold air nozzle 4 through the cold air pipe 15. The cold air nozzle 4 blows on the saw blade to help accelerate the heat dissipation process of the saw blade and further improve the cooling effect.

[0028] The heat sink 8 is hollow inside, and an infusion pump 12 is fixed inside the cooling box 2. The input end of the infusion pump 12 is connected to the cold water tank 6, and the output end of the infusion pump 12 is connected to the heat sink 8.

[0029] With the above structure, the infusion pump 12 can drive the cold water in the cold water tank 6 to be drawn and injected into the heat sink 8, thereby improving the heat absorption effect of the heat sink 8. The infusion pump 12 can maintain the heat dissipation effect of the heat sink 8 by repeatedly drawing and injecting water into the heat sink 8.

[0030] An air filter element 13 is fixed inside the air intake pipe 9.

[0031] With the above structure, the collected cold air can be filtered through the air filter element 13, reducing the amount of dust adhering to the saw blade, thereby reducing saw blade wear and improving cutting efficiency.

[0032] A water inlet 14 is fixed on the cold water tank 6, and the water inlet 14 is connected to the cold water tank 6.

[0033] With the above structure, an external water supply pipe can be connected through the water inlet 14, allowing water to be supplied to the cold water tank 6 to replenish the cold water and facilitate the continuous operation of the cooling process.

[0034] Heat sink 8 is made of copper.

[0035] By adopting the above structure, the excellent thermal conductivity of copper can be used to improve the overall heat absorption and cooling effect and efficiency.

[0036] The working principle of this utility model is as follows: Cold water in the cold water tank 6 is pumped into the cold water pipe 3 by the water pump 11. The cold water pipe 3 is then connected to the cold water nozzle 5 to achieve cold water spraying. The cold water absorbs heat through vaporization, which reduces the temperature of the saw blade. This is a heat transfer cooling method. When the cold water comes into contact with the high-temperature saw blade, the water evaporates rapidly, absorbing a large amount of heat, thereby reducing the surface temperature of the saw blade. At the same time, the air pump 10 draws in cold air and delivers it to the cold air nozzle 4 through the cold air pipe 15. The cold air nozzle 4 blows on the saw blade, which helps to accelerate the heat dissipation process of the saw blade and further improves the cooling effect. The liquid pump 12 drives the pumping of cold water in the cold water tank 6 and injects it into the heat sink 8, thereby improving the heat absorption effect of the heat sink 8. The liquid pump 12 can maintain the heat dissipation effect of the heat sink 8 by repeatedly drawing and injecting water into the heat sink 8.

[0037] In summary, the cold water in the cold water tank 6 is pumped into the cold water pipe 3 by the water pump 11, and then the cold water pipe 3 is connected to the cold water nozzle 5 to achieve cold water spraying. The cold water reduces the temperature of the saw blade by absorbing heat through vaporization, which is a heat transfer cooling method. When the cold water comes into contact with the high temperature saw blade, the water evaporates rapidly, absorbing a large amount of heat, thereby reducing the surface temperature of the saw blade. At the same time, the air pump 10 draws in cold air and delivers the cold air to the cold air nozzle 4 through the cold air pipe 15. The cold air nozzle 4 blows on the saw blade to help accelerate the heat dissipation process of the saw blade and further improve the cooling effect.
