Abstract
The invention discloses a kind of chisels, including chisel body and chisel head；Wherein, chisel head is equipped at least two tips, and groove is equipped between tip and tip, and groove connects two adjacent tips；The features such as present invention is broken, fluting effect.
Description
Technical field
The present invention relates to a kind of chisels.
Background technique
Chisel includes diamond bit, type of broad chiselling etc..Diamond bit is mainly used for crushing effect, rises as high as the banks and is mainly used for fluting effect.
Existing operating environment usually requires to realize by diamond bit and common cooperation of broad chiselling and dig effect.At this point, just needing replacing chisel
It can just work on, and existing chisel is not simultaneously comprising the broken effect with fluting.Moreover, in grooving process, warp
Steel nail can often be encountered, and perhaps cement nail diamond bit is difficult to remove steel nail perhaps cement nail passes through to broad chisel and removes steel nail or cement
Nail, the chisel head position fracture or broken easily broad chiselled.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of chisels.
The present invention, which solves technical solution used by its technical problem, is: a kind of chisel, including chisel body and chisel head；Its
In, chisel head is equipped at least two tips, and groove is equipped between tip and tip, and groove connects two adjacent tips.
Using the setting of at least two tips, in use, when if necessary to use crushing effect, pass through a point
Portion carries out oblique impact, and crushing effect can be realized；When if necessary to use fluting effect, by transverse direction, multiple tips are common
Work, so that forming fluting effect.The broken effect that the same chisel head is incorporated in fluting may be implemented in the setting of such chisel
Fruit.One trough can have broken and fluting effect, and in use, no replacement is required, and chisel can work.Groove herein
Setting plays the effect of buffering and intermediate cutting, so that in use, the power that tip is subject to can be carried out by groove
Buffering, during fluting, if encountering the obstructions such as steel nail or cement nail, can be cut by groove, so that
The obstructions such as steel nail or cement nail are cut off, meanwhile, groove can also remove the clast between two tips, be formed
Fluting effect.
Wherein, tip is equipped with the first cutting face, the first cutting edge and the second cutting face, and the first cutting face is cut with second
Bevel connects the first cutting edge to form tip.
Using the setting in two cutting faces, the first cutting edge is formd, realizes the cutting effect on tip top, further point
The top in portion is equipped with tip, and tip can be used for crushing effect.
Wherein, the angle that the first cutting face and the second cutting face are formed is A, 80 °≤A≤100 °.
The angle setting in two cutting faces, improves the service life of tip and the effect of impact, if angle too small,
Chipping effect is easy in use process, if angle is excessive, impact grinding effect is bad, can not improve broken
Efficiency.
Wherein, the angle that the imaginary extended line of the first cutting edge on two neighboring tip is intersected is B, 100 °≤B≤
150°。
The angle setting that the imaginary extended line of two the first cutting edges is intersected, further increases two tips and works together
Effect, improve whole broken and fluting effect.
Wherein, the first joint face, bottom surface and the second joint face are equipped in groove, the first joint face passes through bottom surface and second
Joint face connection, the other end of the first joint face are connect with adjacent tip, the other end of the second joint face and adjacent tip
Connection.
The setting of groove plays buffering effect by two joint faces, guarantees the service life of tip, and bottom surface is used for clast
Excision effect.Meanwhile groove can also cut off the obstruction in grooving process, such as steel nail, cement nail or other
Obstruction.
Wherein, the first joint face is equipped with the first secondary cutting face, the first end cutting edge and the second secondary cutting face, and first is secondary
Cutting face forms the first end cutting edge with the second secondary cutting face, and the angle that the two is formed is C, and 100 °≤C≤150 °, second connects
Junction is equipped with third pair cutting face, the second end cutting edge and fourth officer cutting face, and third pair cutting face and fourth officer are cut
Face formed the second end cutting edge, and the angle of the two be D, 100 °≤D≤150 °.
End cutting edge setting on two joint faces, further functions as broken and fluting effect.
Wherein, the first cutting edge and the first end cutting edge and the second end cutting edge are located in same horizontal line.
Whole impact effect is played in the setting of uniform level line, guarantees the stability of stress.
Wherein, the angle that the first joint face and adjacent tip are formed is E, 100 °≤E≤150 °；Second joint face and phase
The angle that adjacent tip is formed is F, 100 °≤F≤150 °
The angle that joint face and the cutting edge of tip are formed is arranged, and further improves whole impact cutting effect.
Wherein, it is equipped with plane in bottom surface, the length of plane is whole bottom surface 1/10th to one third.
Promotion effect is played in the setting of plane, plays the effect of clast removing.
Wherein, the depth of groove is H, and the depth of H is chisel head whole height 1/10th to a quarter.
The restriction of depth of groove further increases whole service life, and groove is too deep, and tip is easy to break, groove mistake
Shallowly, it is poor to be crushed fluting effect.
Wherein, chisel head is alloy material, and chisel head is welded and fixed with chisel body.
Using the setting of alloy material, so that the intensity of chisel head entirety improves, broken better effect.
Wherein, groove is equipped with blade.
Using the setting of blade, whole cutting effect is further increased.
