As the patent No. is 200520119486.7, the Chinese utility model patent of HSS by name has been made certain improvement to the tap of prior art: a kind of HSS, be a body of rod, it comprises a shank, a tooth portion, this tooth portion is connected the front end of this shank, this tooth portion comprises three tappings, offers a chip area between the two adjacent tappings, and the front end cutting edge portion of this each tapping is provided with a bore sword groove.The rear end of this shank is provided with a clamping part, is clipped in this clamping part on one rotor and firmly fixes.These three tappings and three chip areas all are parallel to the axis direction of this HSS.This HSS comprises general with HSS, deep hole HSS, stainless steel HSS, titanium processing HSS, thin plate mild steel HSS, oxidation processes screw tap.The utility model is provided with this bore sword groove, so chip removal is easy, torsion is little, stable accuracy, and the screw tap durability is better, and especially the high speed tapping operation effectiveness for through hole is good.
Though above-mentioned patent has been made certain improvement to the tap that prior art provided,, with regard to the tap of prior art, mainly still there is the deficiency of the following aspects:
1, in the process of tapping,, causes the damage of tap easily because chip removal is insufficient;
2, simultaneously, because the deficiency of its chip removal aspect has also caused the tap that prior art provided to be not suitable for the high speed tapping operation of through hole.
The utility model content
In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of chip removal fully and be applicable to the tap of through hole high speed tapping.
For realizing above-mentioned purpose of the present utility model, the utility model provides a kind of tap, and described tap is a body of rod, and it comprises: a clamping part, described clamping part are arranged at an end of the described body of rod; One tooth portion, described tooth portion is arranged at the other end corresponding with described clamping part on the described body of rod, and described tooth portion comprises the tappings of many groups; The first sword groove, the described first sword groove are formed at described arbitrarily between adjacent two tappings; Wherein, described tap also comprises the front position that is arranged at described tooth portion, and is the second sword groove that angle is provided with the described first sword groove.
According to above-mentioned design of the present utility model, the cross section of the described second sword groove is an arc.
According to above-mentioned design of the present utility model, the top of described tooth portion is formed with a central term.
According to above-mentioned design of the present utility model, also be formed with a wedging portion between the top central term of described tooth portion and the described tapping.
According to above-mentioned design of the present utility model, the angle between described first sword groove and the described second sword groove is that 5 degree are between 20 degree.
According to above-mentioned design of the present utility model, the angle between described first sword groove and the described second sword groove is that 5 degree are between 12 degree.
According to above-mentioned design of the present utility model, the quantity of described tapping is 2 to 6 groups, and corresponding, the quantity of described first sword groove and the described second sword groove also is 2 to 6 groups.
Advantage of the present utility model and beneficial effect be, tap of the present utility model has overcome that the tap of prior art exists, and in the process of tapping, because chip removal is insufficient, causes the damage of tap easily; And because the deficiency of its chip removal aspect, the tap that has also caused prior art to provide is not suitable for the deficiency of the aspects such as high speed tapping operation of through hole.Has chip removal fully and be applicable to the advantage of aspects such as through hole high speed tapping.
