AI Technical Summary
When cutting hard materials, the taper milling cutter with a traditional double-edged convex spiral structure cannot completely absorb the heat of the tool body due to the small spraying of coolant, resulting in a continuous increase in temperature, increasing the cutting load and shortening the service life.
A taper milling cutter assembly with a double-edged convex spiral structure is designed, with an interior hollow state and equipped with cooling components, including a storage cylinder, a pump, a liquid outlet tube, a connecting tube, a fixing cylinder, a fluid conduit, a fixing plate and a temperature sensor. The coolant is injected into the milling cutter through the outlet pipe. The temperature sensor controls the pump to suck the hot coolant back and mix it with the normal temperature coolant, and then pour it into the milling cutter to continuously cool down.
By continuously injecting and recycling coolant, the milling cutter temperature is effectively reduced, the high cutting load is reduced, and the service life of the milling cutter is extended. At the same time, the cooling liquid is flowed to the cutting groove through the liquid conduit, cleaning debris and preventing agglomeration.

[0002] Milling cutter is a kind of metal cutting tool. It plays a very important role in the field of mechanical processing. It can perform various types of processing, including plane milling, contour milling, slot milling, forming milling, etc., which makes the milling cutter a multi-purpose processing tool.
[0003] Traditional double-edged tapered milling cutters with an outward convex spiral structure mostly use water-based coolants. In actual applications, the water-based coolant absorbs heat most efficiently when the temperature is between 30 and 60 degrees Celsius. When the milling cutter is cutting hard materials (such as cemented carbide, tool steel, mold steel, and titanium alloy, etc.), the temperature of the cutter body will rise sharply. Currently, the cooling of the milling cutter body is mostly done by spraying coolant on the cutter body to allow it to absorb heat. However, the amount of coolant sprayed each time is small and cannot completely absorb the heat of the milling cutter. After multiple rounds of cutting, the temperature on the milling cutter will become higher and higher, presenting a high cutting load state, which will aggravate the wear of the milling cutter body and reduce its service life.

[0016] like Figure 1 ,3 , 4, 6, and Figure 7 As shown, in view of the problems in the prior art, the present invention provides a tapered milling cutter assembly with a double-edged outer convex spiral structure, including an equipment body 1, the interior of the milling cutter 110 is hollow, and the side wall thickness of the milling cutter 110 is 1-1.5 cm, the cooling component 3 is fixedly installed inside the equipment body 1, and the interior of the cooling component 3 includes a storage cylinder 310, a pump 311, a liquid outlet pipe 312, a connecting pipe 313, a fixed cylinder 314, a liquid guide pipe 315, a fixed plate 316 and a temperature sensor The storage cylinder 310 is fixedly mounted inside the device body 1, and the two groups of pumps 311 are respectively fixedly mounted at the upper and lower ends of the storage cylinder 310. The upper end of the liquid outlet pipe 312 is fixedly connected to the liquid outlet of one group of pumps 311. The other end of the liquid outlet pipe 312 is located inside the milling cutter 110, and there is a gap between the liquid outlet pipe 312 and the bottom end of the milling cutter 110. The temperature sensor 317 is fixedly mounted on the upper end of the fixed plate 316, and the temperature sensor 317 and the pump 311 are electrically connected.
[0017] In the present invention, the interior of the milling cutter 110 is hollow, and the pump 311 will inject the coolant into the interior of the milling cutter 110 through the liquid outlet pipe 312. The coolant will continue to absorb the heat emitted by the milling cutter 110, and when the temperature sensor 317 detects that the internal temperature of the milling cutter 110 exceeds the range of 30-60 degrees Celsius, it will control the pump 311 to suck the coolant inside the milling cutter 110 back to the interior of the storage cylinder 310, mix it with the coolant at normal temperature, and then re-inject the mixed coolant into the interior of the milling cutter 110 to continuously cool the milling cutter 110. There is also a group of temperature sensors 317 inside the storage cylinder 310, which will detect the temperature of the coolant inside the storage cylinder 310 in real time. Once its temperature exceeds 60 degrees, the pump 311 installed on the top will suck out the coolant inside it and replace the coolant to ensure that the coolant is always in a state of efficient heat absorption, thereby preventing the milling cutter 110 from aggravating its wear due to excessive temperature.
[0018] like Figure 3 , 4 as well as Figure 6 As shown, a group of temperature sensors 317 are fixedly connected to the interior of the storage cylinder 310, and the temperature sensor 317 is electrically connected to a pump 311 located at the upper end of the storage cylinder 310.

[0019] In the present invention, when the coolant enters the milling cutter 110 through the liquid outlet pipe 312, a part of the coolant will enter the interior of the fixed cylinder 314 through the connecting pipe 313. When the interior of the milling cutter 110 is filled with coolant, the interior of the fixed cylinder 314 is also filled with coolant. During the cutting process, the coolant will flow out through the leakage hole opened on the liquid guide pipe 315, and then flow downstream through the cutting groove on the milling cutter 110. While cooling the surface of the milling cutter 110, it can also wash away the debris located inside the cutting groove of the milling cutter 110 to prevent these debris from agglomerating inside the cutting groove due to excessive temperature.

The connecting plate 210 is fixedly connected to the upper middle position of the outer wall of the device body 1, and the upper end of the connecting plate 210 is fixedly connected to multiple groups of motors 211, and the output shaft of the motor 211 is fixedly connected to one end of the threaded rod 212, and the other end of the threaded rod 212 is rotatably connected to the fixed plate 216, and the threaded rod 212 and the connecting plate 210 are rotatably connected. The threaded rod 212 is threadedly connected to the protrusion fixedly connected on the outer wall of the extrusion plate 213, and the extrusion plate 213 is slidably connected to the device body 1 On the outer wall, the lower end of the extrusion disk 213 is fixedly connected to the upper end of the airbag 214, the upper end of the airbag 214 is provided with multiple groups of air inlets, and a one-way valve is fixedly installed inside the air inlet, the bottom of the airbag 214 is fixedly connected to the upper end of the fixed disk 216, there is a gap between the inner side wall of the airbag 214 and the equipment body 1, the inside of the airbag 214 is fixedly connected with multiple groups of springs 215, the bottom of the airbag 214 is provided with multiple groups of air outlet holes, the air outlet holes at the bottom of the airbag 214 are fixedly connected to one end of the conduit 217, the other end of the conduit 217 is fixedly connected to the upper end of the air outlet 218, the lower end side wall of the air outlet 218 is provided with multiple groups of air outlet holes, the air outlet 218 is located at the upper end of the liquid outlet hole on the liquid guide tube 315, and there is a gap between it and the milling cutter 110.
[0021] While the milling cutter 110 in the present invention is performing cutting work, the motor 211 will also be started, which will drive the threaded rod 212 to rotate, thereby pushing the extrusion plate 213 to move slowly downward, thereby squeezing the airbag 214. At this time, the gas inside the airbag 214 will be ejected through the air outlet 218 after being squeezed, and the air outlet 218 is located at the upper end of the liquid guide tube 315. The gas will blow the upward debris downward, which can not only change the direction of the debris movement and prevent it from clogging the liquid outlet on the liquid guide tube 315, but also the gas blowing on the surface of the milling cutter 110 can also have a certain cooling effect, and can also blow part of the debris off the milling cutter 110, reducing the debris in the cutting groove on the milling cutter 110.
[0022] Working principle: The connecting block 111 in the present invention is connected to the rotating structure on the cutting device, thereby driving the entire device body 1 to perform cutting work. While the milling cutter 110 is performing cutting work, the motor 211 will also start, which will drive the threaded rod 212 to rotate, thereby pushing the extrusion disk 213 to move slowly downward, thereby squeezing the airbag 214. At this time, the gas inside the airbag 214 will be ejected through the air outlet 218 after being squeezed, and the air outlet 218 is located at the upper end of the liquid guide tube 315. The gas will blow the upward debris downward, which can not only change the direction of the debris movement , preventing it from clogging the liquid outlet on the liquid guide tube 315, and the gas blowing on the surface of the milling cutter 110 can also have a certain cooling effect, and can also blow some debris off the milling cutter 110, reducing the debris in the cutting groove on the milling cutter 110. The inside of the milling cutter 110 is in a hollow state, and the pump 311 will inject the coolant into the inside of the milling cutter 110 through the liquid outlet pipe 312. The coolant will continue to absorb the heat emitted by the milling cutter 110, and when the temperature sensor 317 detects that the internal temperature of the milling cutter 110 exceeds the range of 30-60 degrees Celsius, it will control the pump 311 to pump the milling cutter 110. The coolant in the storage cylinder 10 is sucked back into the storage cylinder 310 and mixed with the coolant at normal temperature. The mixed coolant is then refilled into the milling cutter 110 to continuously cool the milling cutter 110. A set of temperature sensors 317 are also present inside the storage cylinder 310 to detect the temperature of the coolant in the storage cylinder 310 in real time. Once the temperature exceeds 60 degrees, the pump 311 installed on the top thereof will suck out the coolant inside and replace the coolant to ensure that the coolant is always in a state of efficient heat absorption, thereby preventing the milling cutter 110 from aggravating its wear due to excessive temperature. When the coolant enters the milling cutter 110 through the liquid outlet pipe 312, a part of the coolant will enter the interior of the fixed cylinder 314 through the connecting pipe 313. When the interior of the milling cutter 110 is filled with coolant, the interior of the fixed cylinder 314 is also filled with coolant. During the cutting process, the coolant will flow out through the leakage hole opened on the liquid guide pipe 315, and then flow downstream through the cutting groove on the milling cutter 110. While cooling the surface of the milling cutter 110, it can also wash away the debris inside the cutting groove of the milling cutter 110 to prevent the debris from agglomerating inside the cutting groove due to excessive temperature.
