Abstract
The utility model discloses a carbide digital cutting, its technical scheme main points are carbide digital cutting, including triangular blade, triangular blade includes cutting edge, main cutting face, vice cutting face, the triangular blade center is equipped with the fixed orifices, triangular blade is equipped with guide scrap groove along main cutting face, guide scrap groove one end extends to the cutting edge, guide scrap groove keeps away from the one end radius angle of cutting edge, following its width direction in the guide scrap groove and being equipped with the bar groove, the bar groove is at least two, bar groove along guide scrap groove length direction interval setting. When the cutting was used, the cutting crushed aggregates can be derived along with guide scrap groove, avoided cutting the crushed aggregates and piled up and make cutting edge wearing and tearing aggravation, and on the other hand guide scrap groove makes the cutting edge more sharp -pointed, therefore the chip breaking effect is better, and the bar groove can let the bar crushed aggregates that does not cut off derive along it, and blocks that its cutter body to the lathe moves, at the one end radius angle of keeping away from the cutting edge, has blockked further that the cutting crushed aggregates moves to the cutter body.
Description
Technical field
The utility model relates to a kind of lathe tools, and more particularly, it relates to a kind of hard alloy numerical control blade.
Background technology
Turning cutting tool is the cutter that numerically controlled lathe is conventional, it will to manufacture in advance and with the polygonal insert of several cutting edges, a kind of cutter on cutter hub is clamped in by the method that machinery is clamping, after when an in use cutting edge blunt, as long as by the clamping and release of blade, transposition or more allowing blade replacement, more just can continue to use through clamping.
Digital cuttings is the general name of index lathe paring blade, is the main product of modern metal cutting application.Be mainly used in the fields such as the turning of metal, milling, cut-out grooving, thread turning.
Blade is divided into main cutting face and secondary cutting face usually, as the term suggests main cutting face is the blade directly participating in metal cutting, secondary cutting face is the blade in the face of machined surface, and therefore the wearing and tearing of blade are mainly concentrated between which.
At present, digital cuttings disclosed on market, often structure is single, chip breaking weak effect, and stable cutting is poor, and cut particle and easily pile up on blade, cutting edge more easily weares and teares, work efficiency drop.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of simple and reasonable, good hard alloy numerical control blade of chip breaking effect.
For achieving the above object, the utility model provides following technical scheme: a kind of hard alloy numerical control blade, comprise triangular blade, described triangular blade comprises cutting edge, main cutting face, secondary cutting face, described triangular blade center is provided with fixing hole, described triangular blade is provided with dregs guiding groove along main cutting face, described dregs guiding groove one end extends to cutting edge, described dregs guiding groove is away from one end rounding of cutting edge, bar-shaped trough is provided with along its width in described dregs guiding groove, bar-shaped trough at least two, bar-shaped trough is arranged along dregs guiding groove length direction interval.
The utility model is set to further: described dregs guiding groove and bar-shaped trough are symmetricly set in the upper and lower surface of triangular blade.
The utility model is set to further: described triangular blade surface is provided with stator, and described stator is uniformly distributed along fixing hole center.
The utility model is set to further: the dregs guiding groove on described triangular blade is three and about fixing hole Central Symmetry.
The utility model is set to further: main cutting face and the secondary cutting face angle of described triangular blade are 80 degree.
The utility model is set to further: described dregs guiding groove length is 7 to 8 millimeters.
The utility model is set to further: described triangular blade material is carbide alloy.
Compared with prior art, the utility model has the advantage of: by such setting, when cutting use, cut particle to derive with dregs guiding groove, avoid cutting particle accumulation and make cutting edge wearing and tearing aggravation, dregs guiding groove makes cutting edge more sharp-pointed on the other hand, therefore chip breaking better effects if; And bar-shaped trough can allow the bar shaped particle do not cut off derive along it, and stop that its cutter body to lathe moves, at one end rounding away from cutting edge, block cutting particle further and move to cutter body.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model hard alloy numerical control blade embodiment is described further.
A kind of hard alloy numerical control blade, comprise triangular blade 1, triangular blade 1 comprises cutting edge 2, main cutting face 3, secondary cutting face 4, triangular blade 1 center is provided with fixing hole 7, triangular blade 13 is provided with dregs guiding groove 5 along main cutting face, dregs guiding groove 5 one end extends to cutting edge, therefore cutting edge 2 is realized more sharp-pointed, chip breaking Be very effective promotes, dregs guiding groove 5 is away from one end rounding of cutting edge 2, avoid cutting particle toward cutter body movement further, bar-shaped trough 51 is provided with in the width direction in dregs guiding groove 5, bar-shaped trough 51 at least two, bar-shaped trough 51 is arranged along dregs guiding groove 5 length direction interval, before use, first by fixing hole 7, itself and cutter are fixed, further in use, cutting particle can be derived with it by dregs guiding groove 5, and avoid piling up and unstable wear at cutting edge 2 place, bar-shaped trough 51 has guide effect for cutting particle, allow cutting particle helical form move shift out, and cut particle along dregs guiding groove 5 and move friction eceleration, therefore avoid and cut particle and splash, cause user injured.
Preferably, dregs guiding groove 5 and bar-shaped trough 51 are symmetricly set in triangular blade 1 upper and lower surface, and therefore very convenient during assembling, positive and negative is all applicable, is also the utilization rate that improve material, and one side is damaged another side and continued to use; Triangular blade 1 surface is provided with stator 6, and stator 6 is uniformly distributed along fixing hole 7 center, adds frictional force by stator 6, and stability when making fixing is better, avoids cutter because of vibration skew, machining accuracy further may be caused to reduce.
Preferably, the dregs guiding groove 5 on triangular blade 1 is three and about fixing hole 7 Central Symmetry; In use, it is divided into three can use face, and cutter is hit when having damaged blade in face wherein, and can take off this triangular blade 1, the blade turning to another new continues to use, simple to operate, and conservation.
Preferably, main cutting face 3 and secondary cutting face 4 angle of triangular blade 1 are 80 degree, and dregs guiding groove 5 length is 7 to 8 millimeters; By reasonably calculating comprehensive analysis, the fixing and processing effect adopting this angle to realize is best, avoids cutting edge 2 and easily breaks, breaks, and namely the dregs guiding groove 5 of this length ensure that cutting particle can derive smoothly, turn avoid it and longly loses derivation effect.
Triangular blade 1 material is carbide alloy, carbide alloy is a kind of alloy material be made up by powder metallurgical technique of the hard compounds of refractory metal and binding metal, it has high rigidity and wearability, and the material as cutter can ensure the precision of processing, and service life is longer simultaneously.
Below be only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
