Description

Technical Field

[0001] The utility model relates to the technical field of metal ceramic blades, in particular to a self-cooling metal ceramic blade. Background Art

[0002] Metal ceramic blades are a composite material composed of a metal matrix and ceramic particles. They have high hardness and wear resistance and are widely used in the field of mechanical processing.

[0003] Common metal ceramic blades will generate a lot of heat when cutting at high speed for a long time or cutting a large amount. This heat will cause the ceramic particles to fall off or deteriorate due to the high temperature, thus affecting the cutting effect and service life. In order to prevent the metal ceramic blades from being affected by high temperature, workers generally use coolant to spray on the cutting area to achieve the purpose of cooling. However, direct and frequent spraying of coolant can easily cause waste of coolant.

[0004] Therefore, we need a self-cooling metal ceramic blade to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] (1) The utility model is a self-cooling metal ceramic blade. When in use, part of the coolant can be first injected into the upper heat sink and the lower heat sink through the upper oil filling hole and the lower oil filling hole. Then, when the whole body rotates at a high speed to cut the material, the coolant will rotate inside the upper heat sink and the lower heat sink due to the rotation, thereby dissipating heat on the whole surface in all directions.

A coolant is provided, and a cover plate 26 is provided at the upper end of the upper heat dissipation groove 23 and the lower end of the lower heat dissipation groove 25. Part of the coolant is injected into the upper heat dissipation groove 23 and the lower heat dissipation groove 25 through the upper oil filling hole 22 and the lower oil filling hole 24. Then, when the whole body rotates at a high speed to cut the material, the coolant will rotate inside the upper heat dissipation groove 23 and the lower heat dissipation groove 25 due to the rotation, thereby dissipating the heat of the whole surface in all directions. By providing the annular upper heat dissipation groove 23 and the lower heat dissipation groove 25, the coolant can flow in the upper heat dissipation groove 23 and the lower heat dissipation groove 25 in a circular shape, and then the heat dissipation effect can be achieved while the coolant can be recycled, thereby achieving the heat dissipation effect while avoiding the waste of coolant.

[0022] Furthermore, the mounting holes 11 are distributed in a ring shape on the upper surface of the base 1 , and the mounting holes 11 penetrate the base 1 . The outer surface of the base 1 is fixedly connected to the inner surface of the connecting ring 2 . When in use, the whole can be connected and fixed to the device through the mounting holes 11 .

[0023] Furthermore, the heat dissipation hole 21 passes through the connecting ring 2, the upper oil filling hole 22 penetrates into the interior of the upper heat dissipation groove 23, and the lower oil filling hole 24 penetrates into the interior of the lower heat dissipation groove 25. When in use, the upper oil filling hole 22 is positioned higher and located in the oil filling groove 12 on the left, which can facilitate the staff to inject coolant into the upper heat dissipation groove 23, and the lower oil filling hole 24 is positioned lower and located in the oil filling groove 12 on the right, which can facilitate the staff to inject coolant into the lower heat dissipation groove 25.

[0024] Furthermore, the upper heat dissipation groove 23 and the lower heat dissipation groove 25 are fixedly connected to the cover plate 26, and a curved protrusion 261 is fixedly installed on the upper surface of the cover plate 26. The curved protrusion 261 is distributed in a ring shape on the upper surface of the cover plate 26. When the blade body 3 rotates rapidly to cut the material, by setting the curved protrusion 261 distributed in a ring shape, some sticky materials can be effectively prevented from adhering to the blade surface, thereby affecting the cutting effect.

[0025] Working principle: The utility model is a self-cooling metal ceramic blade. When in use, the staff can first inject part of the coolant into the upper heat sink 23 and the lower heat sink 25 through the upper oil filling hole 22 and the lower oil filling hole 24. By setting the oil filling groove 12, it is convenient for the staff to replace the coolant. After the coolant is located in the upper heat sink 23 and the lower heat sink 25, when the whole body rotates at high speed to cut the material, the coolant will also circulate in the upper heat sink 23 and the lower heat sink 25 in an annular manner, thereby comprehensively dissipating heat and cooling the whole. At the same time, the cooling can also be recycled, thereby ensuring the heat dissipation effect while avoiding the waste of coolant, increasing the overall practicality, and by setting the curved protrusion 261, some sticky materials can be prevented from adhering to the blade surface to affect the cutting effect, enriching the overall function.
