Description
Technical field
The utility model is related to metal cutting tool, more particularly to a kind of three faces sword wire rod quality.
Background technology
Three face sword wire rod qualities are relatively conventional cutting tools in metal cutting industry, are generally used for milling groove and step.
This three faces sword wire rod quality has cutting edge in cylindrical and two end faces near cylindrical positions, can be divided into welded type, monoblock type,
Detachable blade formula three types；The cutter hub and matrix of general welded type and the face sword wire rod quality of monoblock type three are integral structure, knife
After body is impaired, it is impossible to be individually replaced cutter hub, cause cutter to be integrally continuing with, greatly waste is caused；Detachable blade
Cutter hub on the face sword wire rod quality of formula three is the small blade of alternating inclinations arrangement, and complex structure runs into part material in process
When expecting uneven microstructure or discontinuously processing, single small blade low intensity, impact resistance is poor, and cutter hub is easily because of the cutting of unexpected increase
Power is damaged, meanwhile, during general machining, the single small blade area of cut is small, and cutter hub is impaired fast, frequently more allowing blade replacement
High cost, processing efficiency is low.
The content of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, there is provided a kind of simple structure,
Low cost, intensity is high, three face sword wire rod qualities of good impact resistance.
The purpose of this utility model can be realized by following technical proposal：A kind of three face sword wire rod qualities, including in bipyramid
The cutterhead of body structure, long blade, bolt, the upper and lower conical surface of bicone of the cutterhead be with horizontal plane in 20 ° of the conical surface, it is described
The upper and lower conical surface of cutterhead is respectively evenly equipped with six chip pockets, and upper conical surface chip pocket relative with the lower conical surface is interspersed, in the chip pocket
Wall left side is provided with blade installation slot, and described blade installation slot two faces junction directly with circumferential notch, is easy to the rimmer knife
Piece is installed in place, gapless, and the cutterhead bicone central plane carries handle of a knife mounting hole and four screw fixed holes, described
The length L of long blade is equal to 1/cos20 ° of the inverse cosine value of processing workpiece groove depth H, i.e., L=H/cos20 °, the long blade upper band
There is chip-breaker, the chip-breaker is interspersed in adjacent long blade on the same face in the upper and lower conical surface, the long blade passes through spiral shell
Bolt is fixed in the blade installation slot of the upper and lower conical surface of cutterhead.
Preferably, described cutterhead is made up of high-speed steel.
Preferably, the long blade is made up of hard alloy, its anterior angle is 12 °, and its relief angle is 0 °
Preferably, the handle of a knife mounting hole that carries of the cutterhead bicone central plane and four screw fixed holes can lead to
Bolt is crossed quickly three described face sword wire rod qualities are fixed on handle of a knife.
Compared with prior art, the utility model simple structure, runs into part material uneven microstructure in process
Or when discontinuously processing, long blade intensity is high, impact resistance is strong, and cutter hub can bear the cutting force of unexpected increase, not easily damaged, together
When, during general machining, the long blade area of cut is big, is damaged slowly, without frequently replacing, effectively reduces and uses
Cost, it is high in machining efficiency.

Specific embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
The every other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.
As illustrated, the utility model provides a kind of three faces sword wire rod quality, including in the cutterhead 1 of bicone structure, rimmer knife
Piece 2, bolt, the upper and lower conical surface of bicone of the cutterhead 1 be with horizontal plane in 20 ° of the conical surface, the cutterhead about 1 the conical surface it is each
Six chip pockets 9 are evenly equipped with, upper conical surface chip pocket 9 relative with the lower conical surface is interspersed, the inwall of the chip pocket 9 left side is provided with
Blade installation slot 5,5 liang described of blade installation slot faces junction directly with circumferential notch 4, is easy to the long blade 2 to be installed to
Position, gapless, the bicone central plane of the cutterhead 1 carries handle of a knife mounting hole 3 and four screw holes 8, the long blade 2
Length L is equal to 1/cos20 ° of the inverse cosine value of processing workpiece groove depth H, i.e., L=H/cos20 °, chip-breaker is carried in the long blade 2
7, the chip-breaker 7 is interspersed in adjacent long blade 2 on the same face in the upper and lower conical surface, and the long blade 2 is solid by bolt
Due in the blade installation slot 5 of cutterhead conical surface about 1.
After using said structure, it is characterized in：In process, the three faces sword wire rod quality runs into part material tissue
Uneven or when discontinuously processing, long blade intensity is high, and impact resistance is strong, and cutter hub can bear the cutting force of unexpected increase, be difficult
It is impaired, meanwhile, during general machining, the long blade area of cut is big, is damaged slowly, without frequently replacing, effective drop
Low use cost, improves processing efficiency.
