Abstract
The utility model relates to a slot blade, particularly relates to the slot blade for recessing on a work piece and belongs to the field of a machining tool. The slot bade comprises a cutter body, wherein the cutter body is fixedly provided with a cutting edge and a rear cutter face is arranged on the cutting edge; and a rear cutter face included angle is formed by the rear cutter face. The slot blade is characterized in that the angle of the rear cutter face included angle is 4.5-5.5 degrees. The slot blade disclosed by the utility model has a reasonable structural design; and the rear cutter face included angle is increased so that the cutting edge is sharper and the chip removal resistance is smaller.
Description
Technical field
The utility model relates to a kind of slot blade, particularly relates to a kind of slot blade that is used for recessing on workpiece, belongs to the process tool field.
Background technology
Slot blade is used for recessing on workpiece, and it comprises cutter hub, is fixed with blade on the cutter hub, has the back knife face on the blade, and back knife face has back knife face angle.The angle of the back knife face angle of the slot blade of prior art is 3.7 °～4.3 °, causes blade sharp inadequately, and the chip removal resistance is big.
The utility model content
The utility model technical problem to be solved is to overcome deficiency of the prior art and a kind of reasonable in design, blade is sharper, the chip removal resistance is littler slot blade are provided.
The technical scheme that the utility model solves the problems of the technologies described above employing is: a kind of slot blade; Comprise cutter hub, be fixed with blade on the cutter hub, have the back knife face on the blade; Back knife face has back knife face angle, is characterised in that: the angle of said back knife face angle is 4.5 °～5.5 °.
The angle of the said back of the utility model knife face angle is 5 °.
The utility model compared with prior art has following advantage and effect: reasonable in design, increased back knife face angle, and make blade sharper, the chip removal resistance is littler.
Description of drawings
Fig. 1 is the plan structure sketch map of the utility model embodiment.
Fig. 2 is the structural representation of facing of the utility model embodiment.
Fig. 3 is the side-looking structural representation of the utility model embodiment.
Fig. 4 is the partial structurtes sketch map of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is described further.
Referring to Fig. 1～Fig. 4, the utility model embodiment comprises cutter hub 1, is fixed with blade 2 on the cutter hub 1, and cutter hub 1 is as a whole with blade 2, is processed by carbide alloy.Have back knife face 3 and main cutting edge 4 on the blade 2.Back knife face 3 has back knife face angle.Back knife face angle is claimed relief angle again.These are prior aries.
The angle of back knife face angle is 4.5 °～5.5 °, and optimal angle is 5 °, has increased back knife face angle, make that like this blade 2 is sharper, and the chip removal resistance is littler, and especially when the car arc groove, chip removal resistance ratios prior art descends at least 20%.
Claims (2)
