Description
Technical field
This utility model belongs to cutting element field, is specifically related to a kind of HSS.
Background technology
Screw tap is the requisite apparatus of machining, and traditional screw tap 26S Proteasome Structure and Function is single, if using general screw tap, chip removal is slow, and tapping working performance is low, and for deep hole or baroque cut thing and then easily snap off, the service life of screw tap shortens.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of HSS, in order to solve the problems referred to above.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of HSS, including tooth portion and shank, described tooth portion is connected to the front end of shank, the rear end of described shank is provided with a clamping part, described HSS is provided with the through hole run through from clamping part rear end to tooth portion, the top in described tooth portion is formed with a central term, described tooth portion includes some groups of tappings, the rear side of the direction of advance of each tapping is provided with chamfering, chip area is offered between the tapping of adjacent sets, being provided with graduation mark on described chip area, the cutting edge portion, front end often organizing tapping is provided with bore sword groove.
Further, described some tappings and chip area are parallel to the axis direction of this HSS.
Further, the port of export of described through hole is arranged on chip area, and the port of export of through hole is the most in an inverted cone.
Further, described HSS includes three tappings and three chip areas.
Further, described HSS includes four tappings and four chip areas.
The beneficial effects of the utility model: this utility model is provided with this bore sword groove, chip removal is easy, torsion is little, stable accuracy, screw tap durability is more preferable, for horizontal type deep hole and complex-shaped by cutting thing, when cutting oil supply is the most sufficient, effect is fine, cutting oil can sufficiently supply tapping, after avoiding chip blocking to affect this tapper tap tapping of tapping, screw tap tooth will not carry the iron filings after cutting, and rear side does not has sharp relief angle, ensure that the screw thread attacked during screw tap backhaul still stands intact, improve conforming product rate.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation according to the HSS described in this utility model embodiment.
In figure:
1, shank；2, tooth portion；3, through hole；12, clamping part；21, central term；22, tapping；23, chamfering；24, chip area；25, graduation mark；26, bore sword groove.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained, broadly fall into the scope of this utility model protection.
As shown in Figure 1, according to a kind of HSS described in this utility model embodiment, including tooth portion 2 and shank 1, described tooth portion 2 is connected to the front end of shank 1, the rear end of described shank 1 is provided with a clamping part 12, described HSS is provided with the through hole 3 run through from clamping part 12 rear end to tooth portion 2, the top in described tooth portion 2 is formed with a central term 21, described tooth portion 2 includes some groups of tappings 22, the rear side of the direction of advance of each tapping 22 is provided with chamfering 23, chip area 24 is offered between the tapping 22 of adjacent sets, it is provided with graduation mark 25 on described chip area 24, often the cutting edge portion, front end of group tapping 22 is provided with bore sword groove 26.
Described some tappings 22 and chip area 24 are parallel to the axis direction of this HSS.
The port of export of described through hole 3 is arranged on chip area 24, and the port of export of through hole 3 is the most in an inverted cone.
Described HSS includes three tappings 22 and three chip areas 24.
Described HSS includes four tappings 22 and four chip areas 24.
This utility model is for horizontal type deep hole and complex-shaped by cutting thing, when cutting oil supply is the most sufficient, effect is fine, cutting oil can sufficiently supply tapping, after avoiding chip blocking to affect this tapper tap tapping of tapping, the rear side of tapping is with chamfering, after screw tap tapping, the iron filings of cutting are easy to be fallen down by chip area, do not stick on screw tap tooth, it is provided with this bore sword groove, chip removal is easy, torsion is little, stable accuracy, screw tap durability is more preferable, and owing to it is provided with chamfering, also it is not easy during backhaul to damage the screw thread attacked, can ensure that screw thread is intact, ensure the most further and improve yields.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
