Embodiment approach 1
[0023] Such as figure 1 , Figure 5-Figure 8 As shown, the high-efficiency self-cooling reamer of the first embodiment of the present invention is specifically a hand reamer or a machine reamer or an adjustable or combined or solid carbide or welded or integrated or other reamer The cutting edge 8 or the chamfering edge 9 or the reamer whose cutting edge 8 is a straight edge or a tapered edge or a blade includes a tool handle 1 and a tool head 2, the tool handle 1 and the tool head 2 are connected or formed as one, and the tool head 2. A plurality of cutting blades or cutting bars 3 are integrally provided, and each cutting blade or cutting bar 3 has a cutting surface 11, and the axial front portion of the cutting surface 11 is chamfered to form a chamfered surface, The rear side of the cutting surface 11 facing the cutting direction is the rear cutting surface 4, the surface outside the top of the cutting surface 11 is the minor cutting surface 6, the cutting surface 11 inte...
Embodiment approach 2
[0028] Such as Figure 2-3 , Figure 5-Figure 8 As shown, the embodiment of the self-cooling reamer of the second embodiment of the present invention is based on the first embodiment. In this embodiment, a notch edge 20 is provided on the main cutting edge 21, and the notch edge 20 is directed to The cutting surface 7 extends to form a groove 19, and the setting of the notch edge 20 is applied to a reamer with a relatively short edge of the tool head, and the implementation effect is the same as that of the first embodiment.
Embodiment approach 3
[0030] Such as Figure 4 , Figure 5-Figure 8 As shown, the embodiment of the self-cooling reamer of the third embodiment of the present invention, on the basis of the first - second embodiment, this embodiment is to apply the above technology to the spiral reamer, the implementation effect and implementation Method 1 has the same result.
[0031] According to the above structure, it has been proved that the effect of cooling the tool from the cutting place by the coolant is far greater than that achieved by flowing downward from the top. On the one hand, the waste chips cut by the tool also prevent the coolant from reaching the cutting place effectively, but the way of sending the coolant directly to the cutting place through the cooling pipe does not have the above defects, so the waste chips can be effectively pushed out and the auxiliary cutting is reduced. The frictional strength of the blade reduces the amount of frictional heat generated, reduces the temperature of th...
