Background technology
The porting knife that grinding center hole operation is used after producer's axle type gear heat both at home and abroad at present is generally 6 ribs or 8 ribs
Top, this porting knife is processed workpiece by the way of crowded cutting, so durable performance and life-span are poor, it is often average with porting knife
500 workpiece of processing, finished surface occurs that scared, finish is poor, influences follow-up alignment process, cylindrical grinding operation processing essence
Degree.As frequently changed porting knife, the extra increase processing cost of meeting.
Utility model content
In order to solve the problems, such as existing prior art, the utility model provides a kind of squeezing and cuts one porting knife, no
Only durable performance is good, long lifespan, and reduces processing cost while crudy is ensured.
Technical scheme described in the utility model is as follows：
A kind of porting knife, the porting knife is to squeeze the porting knife for cutting integral structure, including cutter head 1 and handle of a knife 2.
Further, the cutting portion of the cutter head 1 is fixed with cutter head by welding.
Further, the cutting portion of the cutter head 1 is evenly equipped with a plurality of squeezing and grinds sword 3 and cutting edge 4.
Further, described squeezing grinds sword 3 and cutting edge 4 mutually interval setting, and the cutting portion of cutter head 1 is divided into multiple
Plane 6.
Further, the cutting facial planes of the cutter head 1 at least 8.
Further, it is provided with chip pocket 5 between the crowded blade for grinding sword 3 and cutting edge 4.
Further, 2 points of the handle of a knife is front end and end two parts, and front end is connected with cutter head, end and drilling machine cutter shaft
Connection, distal portion is cylindrical-shaped structure, for concave arc is connected between the front end and end of handle of a knife 2.
Further, 2 points of the handle of a knife is front end and end two parts, and front end is connected with cutter head, end and drilling machine cutter shaft
Connection, distal portion is also the taper column structure with certain angle, for dome arc connects between the front end and end of handle of a knife 2
Connect.
Beneficial effect：Compared with prior art, porting knife provided by the utility model is to squeeze to cut grinding for integral structure
Hole knife, the cutting portion of cutter head 1 is evenly equipped with a plurality of squeezing and grinds sword 3 and cutting edge 4, and cutting edge cutting is completed, and squeezes and grinds sword and play smoothing
Effect, reduces workpiece surface roughness.
Further, 16 blades are set so that workpiece increases with tool contact area, working angles are more steady；It is single
The cutting output of individual sword is reduced, and cutting force reduces, and not only mitigates the labour intensity of operator, and improves cutter life, is sharpened
2400-2600 parts can be once processed, the tool changing frequency is reduced, so as to reduce processing cost.
Further, chip pocket 5 is provided between the crowded blade for grinding sword 3 and cutting edge 4, groove depth depth is continuously increased so that
Velocity gradient is varied less from front to back on every cutting edge in process, it is ensured that working angles are steady.
Brief description of the drawings
Fig. 1 crowded cuts one porting knife for what embodiment was provided；
The crowded left view for cutting one porting knife that Fig. 2 is provided for embodiment；
The crowded sectional view for cutting one porting knife cutter head portion that Fig. 3 is provided for embodiment；
Fig. 4 crowded cuts another schematic diagram in the one bright portion of porting knife knife for what embodiment was provided.
In figure：1- cutter heads, 2- handle of a knifes, 3- is squeezed and is ground sword, 4- cutting edges, 5- chip pockets, 6- planes, 7- welds.
Specific embodiment
The utility model is further elaborated with reference to the accompanying drawings and examples.
Embodiment
Refer to the attached drawing 1 and Fig. 2, a kind of porting knife, the porting knife is to squeeze the porting knife for cutting integral structure, including cutter head
1 and handle of a knife 2, cutting portion and the cutter head of cutter head 1 are fixed in weld 7 by welding.2 points of handle of a knife is front end and end two
Point, front end is connected with cutter head, and end is connected with drilling machine cutter shaft.
The cutting portion of cutter head 1 is K44 wolfram steel hard alloy, is evenly equipped with a plurality of squeezing and grinds sword 3 and cutting edge 4；Described squeezing grinds sword 3
8, and spaced setting are provided with cutting edge 4, the cutting portion of cutter head 1 is divided into eight planes 6；Squeeze and grind the He of sword 3
Chip pocket 5 is provided between the blade of cutting edge 4.
With reference to Fig. 3, cutting portion and the cutter head of cutter head 1 are fixed in weld 7 by welding.2 points of handle of a knife be front end and
End two parts, front end is connected with cutter head, and end is connected with drilling machine cutter shaft, and distal portion is cylindrical-shaped structure, before handle of a knife 2
For concave arc is connected between end and end.
With reference to Fig. 4, the distal portion of the handle of a knife 2 is also the taper column structure with certain angle, before handle of a knife 2
It is convex circular sliding slopes between end and end.
Application method：
1st, porting knife is installed on drilling machine cutter shaft, it is ensured that accurate positioning；
The 2nd, workpiece to be processed is installed, it is ensured that accurate work piece positioning, stabilization；
3rd, drilling machine cutter head handle is pressed to be cut；
4th, cut after the completion of cutter head is cleared up, after the completion of carry out next work piece operations.
In order to better illustrate the beneficial effect of porting knife provided by the utility model, with prior art porting knife from plus
Number amount and processing cost are compared, and are as a result respectively as shown in Table 1 and Table 2, wherein two groups of processing beat keeps one
Cause.
The prior art of table 1 and the utility model porting knife processing quantity statistical form
As can be seen that with prior art porting knife in the case of using same number, the utility model grinds in the middle of from table 1
The piece count of hole knife processing is several times of prior art porting knife processing quantity, and being continuously increased with access times,
The piece count of the utility model porting knife processing is relatively stable, without the apparent reduction of appearance.
The prior art of table 2 and the utility model porting knife processing cost contrast table
As can be seen that the utility model porting knife and prior art porting knife cutter manufacture cost, sharpening in the middle of from table 2
Number, every time sharpening expense all same, but the utility model porting knife once sharpens average processing quantity really prior art porting
5 times of knife are had a surplus, and the cost of corresponding single-piece workpiece is also greatly lowered.Therefore deduce that, what the utility model was provided grinds
Hole knife, not only durable performance is good, long lifespan, and can be effectively reduced processing cost while crudy is ensured.
