Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically a metal cutting tool for high-speed cutting. Background Technology

[0002] The metal cutting process is an interaction between the workpiece and the cutting tool. The cutting tool removes excess metal from the workpiece and, while controlling productivity and cost, enables the workpiece to achieve the geometric accuracy, dimensional accuracy, and surface quality required by the design and process.

[0003] Metal cutting tools on the market generate a lot of heat during use. Traditional solutions often involve cooling the tool by applying coolant to its surface. However, this method cannot completely reduce the tool's temperature. The undissipated heat reduces the tool's lifespan and can cause severe deformation of metal parts. Utility Model Content

The circulating cooling assembly can deliver cooling oil to the sleeve, and the cooling oil enters the tool from the side hole. After absorbing the heat of the tool, the cooling oil enters the annular groove from the guide hole and flows back to the circulating cooling assembly, thereby achieving the purpose of circulating cooling of the tool.

[0007] Preferably, a protrusion extending into the side hole is fixed to the inner end of the sleeve, and a helical blade is fixed to the outside of the protrusion.

[0008] The effect achieved by the above components is that the protruding post can cooperate with the spiral blade to increase the movement of the cooling oil in the side hole, thereby increasing the heat exchange contact time between the tool and the cooling oil and improving the cooling effect on the tool.

[0009] Preferably, the circulating cooling assembly includes an oil tank mounted on the housing, an oil pump connected to the top of the oil tank, an oil pipe connected to the output end of the oil pump and the sleeve end side, and a return pipe connected to the oil tank is connected to the outer side of the sleeve near the annular groove.

[0010] The effect achieved by the above components is as follows: the oil pump can introduce the cooling oil in the oil tank into the side hole of the tool through the oil supply pipe, cool the tool, and then the cooling oil re-enters the oil tank through the return pipe, so as to achieve the purpose of circulating cooling of the tool.

[0011] Preferably, the drive assembly includes a drive motor mounted on the top of the housing, the output shaft of the drive motor is connected to a drive gear, and a gear ring that meshes with the drive gear is fixed to the outside of the rotating base.

[0023] This utility model provides an improved metal cutting tool for high-speed cutting. The technical solution of this utility model is as follows:

[0024] In embodiments of this utility model, such as Figures 1-3As shown, a metal cutting tool for high-speed cutting includes a housing 1, a rotating base 2 rotatably mounted on one side of the housing 1, a detachable tool 3 installed inside the rotating base 2, and a drive assembly 4 for driving the rotating base 2 to rotate, mounted on the top of the housing 1. The drive assembly 4 includes a drive motor 41 mounted on the top of the housing 1, a drive gear 42 connected to the output shaft of the drive motor 41, and a gear ring 43 fixed to the outside of the rotating base 2, meshing with the drive gear 42. The drive motor 41, in conjunction with the drive gear 42 and the gear ring 43, can complete the rotation of the tool 3. For driving purposes, one end of the cutting tool 3 has a side hole 7. A heat exchange assembly 5, fixed to the inner wall of the housing 1, is fitted onto the end of the cutting tool 3 near the side hole 7. The heat exchange assembly 5 includes a sleeve 51. A sealed bearing 53 connected to the end shaft of the cutting tool 3 is provided on the end side of the sleeve 51. An annular groove 52 is provided on the inner wall of the sleeve 51. A guide hole 8 communicating with the side hole 7 is provided on the outer wall of the cutting tool 3. The circulating cooling assembly 6 can deliver cooling oil into the sleeve 51, and the cooling oil enters the cutting tool 3 from the side hole 7. After absorbing heat from the cutting tool 3, the cooling oil flows out from the guide hole 8. The coolant enters the annular groove 52 and flows back to the circulating cooling assembly 6. The guide hole 8 is located inside the annular groove 52. A protrusion 54 extending into the side hole 7 is fixed to the inner end of the sleeve 51. A spiral blade 55 is fixed to the outside of the protrusion 54. The protrusion 54, in conjunction with the spiral blade 55, increases the movement stroke of the cooling oil in the side hole 7, thereby increasing the heat exchange contact time between the tool 3 and the cooling oil and improving the cooling effect on the tool 3. A circulating cooling system installed at the bottom of the housing 1 is connected between the outer side of the sleeve 51 near the annular groove 52 and the end side of the sleeve 51. Component 6, the circulating cooling component 6 includes an oil tank 61 installed on the housing 1. An oil pump 62 is connected to the top of the oil tank 61.

The oil pump 62 can introduce the cooling oil in the oil tank 61 into the side hole 7 of the tool 3 through the oil pipe 63. After cooling the tool 3, the cooling oil re-enters the oil tank 61 through the return pipe 64, thus achieving the purpose of circulating cooling of the tool 3.

[0025] The working principle of the metal cutting tool for high-speed cutting provided by this utility model is as follows: The drive motor 41, in conjunction with the drive gear 42 and the gear ring 43, drives the tool 3 installed in the rotary seat 2 to rotate and complete the high-speed cutting work. The oil pump 62 can introduce the cooling oil in the oil tank 61 into the side hole 7 of the tool 3 through the oil pipe 63. The cooling oil enters the interior of the tool 3 through the side hole 7. The protrusion 54, in conjunction with the spiral blade 55, increases the movement stroke of the cooling oil in the side hole 7, thereby increasing the heat exchange contact time between the tool 3 and the cooling oil. After absorbing the heat of the tool 3, the cooling oil enters the annular groove 52 through the guide hole 8. The cooling oil re-enters the oil tank 61 through the return pipe 64, thereby achieving the purpose of circulating cooling inside the tool 3.
