Abstract
This novel one high abrasion obdurability that relates to is combined PCBN reamer, including handle of a knife, cutter head and point of a knife, described handle of a knife is connected by alignment pin and connecting key with between cutter head, handle of a knife and cutter head are coaxially distributed and handle of a knife front end is embedded in cutter head, cutter head along from front end to end at least two-stage step-like structure, and at least 1 times of rear stage a diameter of previous stage diameter, cutter head side surface sets at least two cutting edges, cutting edge is distributed in the shape of a spiral around cutter head axis, uniform hard chip particles in cutting edge, and hard chip particles is distributed along cutting edge rectangular array, it is threaded connection between point of a knife and cutter head front end face and is coaxially distributed with cutter head.This novel one side can need cutter structure is adjusted flexibly according to use, thus improve the convenience that cutter uses the reparation of motility and cutter, on the other hand, while improving cutter self structure intensity and chip efficiency, the anti-wear performance of the cutting edge of cutter is separately effectively raised.
Description
Technical field
This utility model relates to a kind of high abrasion obdurability and is combined PCBN reamer, belongs to machine tool equipment technical field.
Background technology
Current is the most conventional a kind of machine tool utilizing PCBN reamer, usage amount is huge and applied widely, but find in actual use, presently used PCBN reamer mostly is integral structure, the most in use after reamer part recurring structure is impaired, maintenance recovery rate is low, often directly result in this cutter to scrap, thus cause the serious wasting of resources, too increase the cost of processing, simultaneously, in current rimer structure, especially edge structure is often single alloy structure, although the needs of machining operation can be met, but the anti-wear performance of himself is relatively low, thus also exacerbate the abrasion of cutter self, therefore for this present situation, in the urgent need to developing a kind of novel PCBN reamer cutter structure, to meet the needs of actual production.
Utility model content
This utility model purpose is that and overcomes above-mentioned deficiency, it is provided that a kind of high abrasion obdurability is combined PCBN reamer.
For achieving the above object, this utility model is to be achieved through the following technical solutions:
A kind of high abrasion obdurability is combined PCBN reamer, including handle of a knife, cutter head and point of a knife, described handle of a knife is connected by alignment pin and connecting key with between cutter head, handle of a knife and cutter head are coaxially distributed and handle of a knife front end is embedded in cutter head, cutter head along from front end to end at least two-stage step-like structure, and at least 1 times of rear stage a diameter of previous stage diameter, cutter head side surface sets at least two cutting edges, cutting edge is distributed in the shape of a spiral around cutter head axis, uniform hard chip particles in cutting edge, and hard chip particles is distributed along cutting edge rectangular array, it is threaded connection between point of a knife and cutter head front end face and is coaxially distributed with cutter head.
Further, described point of a knife is to set at least two cutting edges being distributed in the shape of a spiral in pyramidal structure, and the conical surface.
Further, described hard chip particles cumulative volume be cutting edge volume 30% 70%.
This new structure is simple, flexible and convenient to use, on the one hand can need cutter structure is adjusted flexibly according to use, thus improve the convenience that cutter uses the reparation of motility and cutter, on the other hand while improving cutter self structure intensity and chip efficiency, separately effectively raise the anti-wear performance of the cutting edge of cutter, thus reach to improve cutter and use motility and the purpose of stability in use.
Accompanying drawing explanation
Fig. 1 is the structural representation that this is novel.
Detailed description of the invention
A kind of high abrasion obdurability as shown in Figure 1 is combined PCBN reamer, including handle of a knife 1, cutter head 2 and point of a knife 3, it is connected by alignment pin 4 and connecting key 5 between handle of a knife 1 with cutter head 2, handle of a knife 1 and cutter head 2 are coaxially distributed and handle of a knife 1 front end is embedded in cutter head 2, cutter head 2 along from front end to end at least two-stage step-like structure, and at least 1 times of rear stage a diameter of previous stage diameter, cutter head 2 side surface sets at least two cutting edges 6, cutting edge 6 is distributed in the shape of a spiral around cutter head 2 axis, uniform hard chip particles 7 in cutting edge 6, and hard chip particles 7 is distributed along cutting edge 6 rectangular array, it is threaded connection between point of a knife 3 and cutter head 2 front end face and is coaxially distributed with cutter head 2.
In the present embodiment, described point of a knife 3 is to set at least two cutting edges being distributed in the shape of a spiral 6 in pyramidal structure, and the conical surface.
In the present embodiment, described hard chip particles 7 cumulative volume be cutting edge 6 volume 30% 70%.
This new structure is simple, flexible and convenient to use, on the one hand can need cutter structure is adjusted flexibly according to use, thus improve the convenience that cutter uses the reparation of motility and cutter, on the other hand while improving cutter self structure intensity and chip efficiency, separately effectively raise the anti-wear performance of the cutting edge of cutter, thus reach to improve cutter and use motility and the purpose of stability in use.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
