Description

Technical Field

[0001] The present invention relates to the technical field of numerical control tools, and specifically to an energy-efficient conversion type numerical control damping alloy tool. Background Art

[0002] The dampers applied in damping tools are mainly divided into two types: dynamic vibration absorbers and friction dampers. A Chinese invention patent with the application publication number CN114101801B discloses a damping tool, which includes a tool shank, a sleeve, a mass block, a first elastic support ring, a support seat, and damping oil, and further includes a second magnetic member. The first magnetic member and the second magnetic member are arranged with the same poles facing each other. This invention transfers the vibration of the tool shank to the mass block through the damping oil, and uses the principle of like poles repelling each other of the magnetic members to buffer the mass block, greatly reducing the amplitude and vibration frequency of the mass block, thereby effectively reducing the vibration during cutting. A Chinese invention patent with the application publication number CN112247171B discloses a frequency-adjustable passive damping tool shank and a damping tool. The tool shank includes a tool shank body, a dynamic vibration absorption unit, and a tool head connection seat. The tool includes a tool head and a damping tool shank. By changing the air pressure in the adjustment cavity to change the frequency, the frequency of the damping unit is made different from the vibration frequency of the tool shank, avoiding resonance, and reducing the cutting vibration amplitude, enhancing the adaptability of the damping tool shank to various cutting parameters.

[0003] However, the inventor found that during actual use, the heat of the existing tool is exported by opening a hole in the center of the tool shank and flowing in from the tail, and flowing out from the cutting edge of the tool head. The water only flows through the tool body in the center of the damping ring, and the heat exchange efficiency is low. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art. By opening a water flow channel on the limiting groove, the water flow channel is spirally opened on the limiting groove, and the damping component is cooled by water through the water flow channel. The tail of the water flow channel is connected to the water channel, improving the heat exchange efficiency, and enabling more efficient heat exchange of the heat converged at the damping component, solving the problem that the heat of the existing tool is exported by opening a hole in the center of the tool shank and flowing in from the tail, and flowing out from the cutting edge of the tool head, and the water only flows through the tool body in the center of the damping ring with low heat exchange efficiency.

[0005] For the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] An energy-efficient conversion type numerically controlled damping alloy cutting tool, comprising a tool shank, a tool bar, a tool tip and a metal sleeve arranged on the tool bar. At least two groups of limiting grooves are provided on the tool bar, and damping components for damping are arranged on the limiting grooves. A water flow channel is provided on the limiting groove, and an air flow channel is provided on the damping component. A water channel is provided in the tool bar, and the damping component is cooled by water through the water flow channel and cooled by air through the air flow channel.

[0007] As a preference, the damping component includes limiting rings arranged on the front and rear sides and a damping ring clamped between the two limiting rings.

[0008] As a preference, the air flow channel is arranged on the damping ring, the air flow channel is arranged in a spiral shape, and the spiral direction of the air flow channel is the same as the rotation direction when the damping cutting tool is operating.

[0009] As a preference, the water flow channel is arranged in a spiral shape on the limiting groove, and the spiral direction of the water flow channel is the same as the rotation direction when the damping cutting tool is operating.

[0010] As a preference, the water channel penetrates through the tail of the tool bar and is connected to the water flow channel. The tail of the water flow channel is connected to the water channel in the middle part of the tool bar. The water channel penetrates through the tool shank and is connected to the tool tip.

[0011] As a preference, a plurality of obliquely arranged air inlet holes and a plurality of obliquely arranged air outlet holes are provided on the metal sleeve.

[0012] As a preference, the orientation of the air inlet holes points to the rotation direction when the tool is operating.

[0013] As another preference, the orientation of the air outlet holes faces away from the rotation direction when the tool is operating and is opposite to the direction of the air inlet holes.

[0014] The beneficial effects of the present invention:

[0015] 1. In the present invention, by providing a water flow channel on the limiting groove, the water flow channel is arranged in a spiral shape on the limiting groove, and the damping component is cooled by water through the water flow channel. The tail of the water flow channel is connected to the water channel, which improves the heat exchange efficiency and can more efficiently exchange the heat concentrated at the damping component.

[0016] 2. In the present invention, by providing an air flow channel on the damping component, a plurality of obliquely arranged air inlet holes and a plurality of obliquely arranged air outlet holes are provided on the metal sleeve, and the orientation of the air inlet holes points to the rotation direction when the tool is operating. By means of the high-speed rotation during the use of the tool, air flows into the air flow channel at a high speed along the air inlet holes, surrounds the damping component for one circle and takes out the heat, further improving the service performance of the damping component.

[0017] In summary, the device has the advantages of improving the heat exchange efficiency and the service performance of the vibration damping component, and is particularly applicable to the field of numerical control tool technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] Embodiment 1

[0028] As Figures 1 to 5 shown, an energy-efficient conversion type numerical control vibration damping alloy tool includes a tool shank 1, a tool shank 2, a tool tip 3, and a metal sleeve 4 provided on the tool shank 2. At least two groups of limit grooves 21 are provided on the tool shank 2, a vibration damping component 5 for vibration damping is provided on the limit grooves 21, a water flow channel 6 is provided on the limit grooves 21, an air flow channel 7 is provided on the vibration damping component 5, and a water channel 8 is provided in the tool shank 2. The vibration damping component 5 is cooled by water through the water flow channel 6, and the vibration damping component 5 is cooled by air through the air flow channel 7.

[0029] It is worth mentioning here that by opening a water flow channel 6 on the limit groove 21, the water flow channel 6 is spirally opened on the limit groove 21, and the vibration damping component 5 is cooled by water through the water flow channel 6. The tail of the water flow channel 6 is connected to the water channel 8, improving the heat exchange efficiency and enabling more efficient heat exchange of the heat converged at the vibration damping component 5.

[0030] As Figure 4 shown, the vibration damping component 5 includes limit rings 51 arranged on the front and back sides and a vibration damping ring 52 clamped between the two limit rings 51.

[0031] As Figure 3 、 4 shown, an air flow channel 7 is opened on the vibration damping ring 52. The air flow channel 7 is spirally opened, and the spiral direction of the air flow channel 7 is the same as the rotation direction of the vibration damping tool during operation.

[0032] It is worth mentioning here that by opening an air flow channel 7 on the vibration damping component 5, a number of obliquely arranged air inlet holes 41 and a number of obliquely arranged air outlet holes 42 are opened on the metal sleeve 4. The orientation of the air inlet holes 41 points to the rotation direction of the tool during operation. With the high-speed rotation during the use of the tool, air flows into the air flow channel 7 along the air inlet holes 41 at high speed, surrounds the vibration damping component 5 for one circle to carry away heat, further improving the performance of the vibration damping component; by setting the spiral direction of the air flow channel 7 to be the same as the rotation direction of the vibration damping tool during operation, the flow rate of the passing gas can be increased, more heat can be carried away, and the heat exchange efficiency can be improved.

[0033] As Figure 2 、 3 shown, the water flow channel 6 is spirally opened on the limit groove 21, and the spiral direction of the water flow channel 6 is the same as the rotation direction of the vibration damping tool during operation.

[0034] In this example, by setting the spiral direction of the water flow channel 6 to be the same as the rotation direction of the vibration damping tool during operation, the flow rate of the passing water can be increased, more heat can be carried away, and the heat exchange efficiency can be improved.

[0035] As Figure 2 、 3 shown, the water channel 8 penetrates through the tail of the tool shank 2 and is connected to the water flow channel 6. The tail of the water flow channel 6 is connected to the water channel 8 in the middle part of the tool shank 2. The water channel 8 penetrates through the tool handle 1 and is connected to the tool tip 3.

[0036] In this example, by setting it like this, the tool tip can be cooled and the vibration damping component 5 can also be cooled at the same time.

[0037] As Figure 5 shown, a number of obliquely arranged air inlet holes 41 and a number of obliquely arranged air outlet holes 42 are opened on the metal sleeve 4.

[0038] As Figure 5As shown, the air inlet 41 is oriented in the direction of rotation of the tool during operation.

[0039] In this embodiment, the air inlet 41 is disposed obliquely and is oriented toward the direction of rotation of the tool during operation, so that more gas can flow in and accelerate the flow of gas into the air channel 7 .

[0040] like Figure 5 As shown, the direction of the air outlet hole 42 is opposite to the direction of the rotation of the tool during operation, which is opposite to the direction of the air outlet hole 41.

[0041] In this example, the air outlet 42 is disposed obliquely and is oriented in the direction of rotation of the tool during operation, so that the gas can flow out faster and the heat exchange efficiency can be improved.

[0042] Embodiment 2

[0043] like Figure 6 As shown, an energy efficient conversion type numerically controlled vibration-damping alloy tool, the water flow channel 6 of which can also be opened in a long strip shape along the circumferential direction on the limiting groove 21.

[0044] In this example, by providing the water flow channel 6 in a long strip shape, the heat on the vibration reduction component 5 can be taken away by more water flow. By providing the water flow channel 6 in a long strip shape, the flow velocity of the water flow is increased, thereby improving the heat exchange efficiency.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical prompts of the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
