Abstract
The utility model discloses a groove-cooling hard alloy threaded blade. The groove-cooling hard alloy threaded blade comprises an upper surface, a lower surface and a blade body, wherein the blade body is used for connecting the upper surface with the lower surface and consists of a plurality of side faces; cutting teeth are arranged on the side faces of the blade body; a cooling hole penetrating through the upper surface and the lower surface is arranged in the blade body; a sunk area is arranged in at least one surface of the blade body, wherein the sunk area is not coplanar with the surface; and the cooling hole is located in the sunk area. The groove-cooling hard alloy threaded blade has the beneficial effects that: as the blade is additionally provided with the sunk area and the cooling hole is located in the sunk area, when cooling liquid flows out of the cooling hole, the cooling liquid firstly flows into the sunk area and then flows from a sidewall of the sunk area to the surfaces and the cutting teeth of the blade; and due to the adoption of the design, the flowing area of the cooling liquid is increased, the blade and the cutting teeth on the blade are more evenly heated, and the incomplete cooling and the phenomenon of cracking arising from uneven heating are avoided.
Description
Technical field
The utility model belongs to the machined part field, is specifically related to the carbide alloy screw thread blade of groove cooling.
Background technology
Existing cutting has a variety of with the type of screw thread blade, be widely used in the cut field.A kind of screw thread blade is wherein arranged, which is provided with the cooling holes that cutting teeth and cooling liquid are flowed through,, need cool off continuously with cooling fluid for reducing the temperature of screw thread blade when the cut.But the cooling holes of existing screw thread blade is arranged near the middle part of blade face mostly, and the diameter of cooling holes has certain limitation, therefore when cut is used the cooling fluid cooling; Above-mentioned cooling fluid flow to blade face by the sidewall of cooling holes, flows to each cutting teeth again, and this mode makes that very easily being heated of blade and cutting teeth is inhomogeneous; Cause cooling not thorough; Inhomogeneous cooling is even, can influence blade life, so that crackle or tipping appears in blade face.
The utility model content
The utility model technical problem to be solved is the deficiency to above-mentioned prior art, and a kind of blade uneven carbide alloy screw thread blade that is heated of avoiding is provided.
The technical scheme that the utility model adopted is: a kind of carbide alloy screw thread blade of groove cooling; Comprise by two surfaces up and down and connect the blade body that several sides on these two surfaces constitute; The side of said blade body is provided with cutting teeth; Said blade body is provided with the cooling holes that runs through its two surfaces, at least one surface of said blade body be provided with one with the depressed area of coplane not, this surface, said cooling holes is positioned at this depressed area.
As preferably, said depressed area has the length that is not less than said cutting teeth projected length on this direction on the length direction of said blade body.
As preferably, said depressed area ovalize.
As preferably, said depressed area is prismatic.
The beneficial effect of the utility model is: owing on blade, set up the depressed area; And cooling holes is positioned at the depressed area, and when cooling liquid flowed out in by cooling holes, it at first imported in the depressed area; Sidewall by the depressed area flow to blade face and cutting teeth again; This design has increased the area that cooling liquid flows out, and makes blade and goes up cutting teeth and be heated more evenly, has avoided thoroughly not sparing the phenomenon that crackle or tipping appear in the blade face that causes with inhomogeneous cooling because of cooling.
