Abstract
The utility model relates to a cold fraising sword in six sword additions of diamond PCD, including blade holder and cutter arbor, be equipped with the tool bit at the tip of cutter arbor, have the cutting edge on the tool bit, the liquid flow that is equipped with the intercommunication in blade holder and the cutter arbor says all, do not is equipped with at the tip of blade holder and cutter arbor and says inlet and the liquid outlet that feeds through all with the liquid flow, being equipped with the blade that six annulars were arranged on the tool bit, having the cutting edge in one side of blade, the orientation of the cutting edge on each blade is same one side, forms the chip groove that extends along cutter arbor length direction between the adjacent blade, and the liquid outlet that the liquid flow was said all lies in the middle part of tool bit, and the degree of depth of the chip groove middle part from the tip of cutter arbor to the cutter arbor becomes shallow gradually, and the bits foam that the reaming produced is followed the chip groove and is in time discharged.
Description
Technical field
The utility model relates to a kind of fraising cutter, cold fraising cutter in the addition of especially a kind of diamond PCD six sword.
Background technology
Reamer has one or more cutter tooth, in order to excise the rotary cutter of hole surface sheet metal, has the rotation finishing tool of straight sword or helical edges, for reaming or repair hole.Reamer in use, most importantly the radiating effect of reamer and the fluency of chip removal is noted, for diamond PCD fraising cutter, the reaming of diamond PCD fraising cutter is to liking diamond, and adamantine material is very hard, if reamer occurs not smooth when chip removal and heat radiation, with regard to easy, damage is caused to blade, reduce reaming efficiency, even have impact on the life-span of reamer, present diamond PCD reams cutter structurally more complicated, heat radiation and chip removal efficiency lower.
Utility model content
The purpose of this utility model is to solve the defect that in prior art, diamond PCD reams existing for cutter, providing cold fraising cutter in the addition of a kind of diamond PCD six sword.
To achieve these goals, the technical solution adopted in the utility model is:
Cold fraising cutter in the addition of a kind of diamond PCD six sword, comprise tool rest and knife bar, cutter head is provided with in the end of knife bar, with blade on cutter head, described tool rest be provided with the fluid flow paths be communicated with in knife bar, be respectively equipped with the inlet and liquid outlet that are communicated with fluid flow paths in tool rest and the end of knife bar;
Described cutter head is provided with the blade of six annular arrangements, in the side of blade with blade, blade on each blade be oriented the same side, formed between adjacent blade along knife bar length direction extend chip area, the liquid outlet of described fluid flow paths is positioned at the middle part of cutter head.
Cold fraising cutter in above-mentioned a kind of diamond PCD six sword addition, described multiple chip area annular arrangement on the side face of knife bar.
Cold fraising cutter in above-mentioned a kind of diamond PCD six sword addition, described chip area extends to the terminate partway of knife bar from the end of knife bar, and the middle part of the degree of depth from the end of knife bar to knife bar of chip area shoals gradually.
Cold fraising cutter in above-mentioned a kind of diamond PCD six sword addition, the afterbody of described tool rest is provided with draw-in groove.
The beneficial effects of the utility model are: in the addition of this diamond PCD six sword, cold fraising cutter carries out cooling process by injecting cooling liquid in fluid flow paths in tool rest and knife bar to tool rest and knife bar and cutter head, in order to strengthen the efficiency of fraising, cutter head is provided with the blade of six annular arrangements, in the side of blade with blade, blade on each blade be oriented the same side, the chip area extended along knife bar length direction is formed between adjacent blade, chip area extends to the terminate partway of knife bar from the end of knife bar, the middle part of the degree of depth from the end of knife bar to knife bar of chip area shoals gradually, the bits foam that reaming produces is discharged in time from chip area, hardness is high, compression strength is high, thermal conductivity and the characteristic such as wearability is good, very high machining accuracy and working (machining) efficiency can be obtained in high-speed cutting, PCD cutter and the affinity between non-ferrous metal and nonmetallic materials very little, in process, chip does not form built-up edge on point of a knife.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is side view of the present utility model.
Detailed description of the invention
Further understand for making to have architectural feature of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1 and Figure 2, cold fraising cutter in the addition of a kind of diamond PCD six sword, comprise tool rest 1 and knife bar 2, cutter head is provided with in the end of knife bar 2, with blade on cutter head, tool rest 1 be provided with the fluid flow paths 3 be communicated with in knife bar 2, be respectively equipped with the inlet 4 and liquid outlet 5 that are communicated with fluid flow paths 3 in tool rest 1 and the end of knife bar 2;
Cutter head is provided with the blade 6 of six annular arrangements, in the side of blade 6 with blade 7, blade 7 on each blade 6 be oriented the same side, formed between adjacent blade 6 along knife bar 2 length direction extend chip area 8, the liquid outlet 5 of fluid flow paths 3 is positioned at the middle part of cutter head.
Further, multiple chip area 8 annular arrangement on the side face of knife bar 2, chip area 8 extends to the terminate partway of knife bar 2 from the end of knife bar 2, and the middle part of the degree of depth from the end of knife bar 2 to knife bar 2 of chip area 8 shoals gradually, and the afterbody of tool rest 1 is provided with draw-in groove 9.
In the addition of this diamond PCD six sword, cold fraising cutter carries out cooling process by injecting cooling liquid in fluid flow paths 3 in tool rest 1 and knife bar 2 to tool rest 1 and knife bar 2 and cutter head, in order to strengthen the efficiency of fraising, cutter head is provided with the blade 6 of six annular arrangements, in the side of blade 6 with blade 7, blade 7 on each blade 6 be oriented the same side, the chip area 8 extended along knife bar 2 length direction is formed between adjacent blade 6, chip area 8 extends to the terminate partway of knife bar 2 from the end of knife bar 2, the middle part of the degree of depth from the end of knife bar 2 to knife bar 2 of chip area 8 shoals gradually, the bits foam that reaming produces is discharged in time from chip area 8.
The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and description; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
