Description
Technical field
The present invention relates to cutting tool technical field, particularly relate to spiral tap.
Background technology
At present when thread mill drilling, need two procedures be adopted, first with drill bit punching, then pass through tap tapping; But above-mentioned process exists following point: 1) owing to adding man-hour, tool changing tool setting need be repeated, processing time error be cut with scissors large, finally cause machining that rear processed hole precision is lower becomes waste product; 2) due to needs repetition tool changing, cause working (machining) efficiency lower; 3) at present the installation of screw tap clamping part is located with counterbore, and locating effect is not good, and when stressed larger clamping part can burst apart.
Summary of the invention
The object of this invention is to provide one can time processing shaping, working (machining) efficiency is low, and the spiral tap avoiding clamping part to burst apart.
Technical scheme of the present invention is as follows:
Spiral tap, comprises clamping part, the handle of a knife that clamping part connects, the cutter head that handle of a knife connects; Described clamping part front end conically; Described cutter head comprises the bore portion of second half section, and the screw tap portion of first half section; Described screw tap portion periphery is evenly equipped with tapping sword vertically; Described screw tap portion is also provided with chip area, and this chip area extends in the shape of a spiral and runs through tapping sword; Institute's bore portion end is provided with apex point.
Described clamping part and handle of a knife one-body molded, and all adopt No. 45 steel; Described handle of a knife welds with cutter head, and this cutter head adopts carbide alloy.Because cutter head adopts carbide alloy, hard alloy wear resistance, heat resistance are strong, thus ensure the wear-resisting and heat resistance of cutter head; And clamping part, handle of a knife adopt No. 45 steel, because No. 45 steel costs are low, thus reduce the production cost of spiral tap.
Described cutter head outer surface has three layers of coating, is followed successively by titanium alloy layer undercoating, titanium nitride layer and TiAlN external coating from inside to outside.Three kinds of coatings are coated on cutter head outer surface thus cutter head outer surface is had characteristics such as hardness is high, good toughness, wearability are good, stable chemical performance, heat-resistant oxidized, coefficient of friction is little, especially firmly wait in difficult-to-machine material in cutting superelevation and can give play to outstanding performance.
Described clamping part outer surface has wear-resistant coating.By hard wear-resistant coating being coated on clamping part outer surface thus making clamping part outer surface wearability good, resistance to elevated temperatures is strong.
The invention has the beneficial effects as follows: by the bore portion of cutter head second half section, can hole; And by tapping sword uniform in cutter head screw tap portion, carry out tapping, thus ensure that boring and tapping are carried out simultaneously, avoid repeating processing, reduce production cost; The discharge of metal fillings is convenient to by the chip area in screw tap portion; Due to head end conically clamping part there is positioning action, and clamping part is solid, and the ability of its allowable stress is comparatively strong, and the clamping part that can effectively avoid bursts apart, and makes the longer service life of spiral tap.

Detailed description of the invention
Embodiment 1
Shown in Fig. 1-Fig. 4, spiral tap, comprises clamping part 1, the handle of a knife 2 that clamping part connects, the cutter head 3 that handle of a knife connects; Described clamping part front end conically, due to head end conically clamping part there is positioning action, and clamping part is solid, and the ability of its allowable stress is comparatively strong, and the clamping part that can effectively avoid bursts apart, and makes the longer service life of spiral tap; Described cutter head comprises the bore portion 4 of second half section, and the screw tap portion 5 of first half section; Described screw tap portion periphery is evenly equipped with tapping sword 6 vertically, by the bore portion of cutter head second half section, can holes, by tapping sword uniform in cutter head screw tap portion, carry out tapping, thus ensure that boring and tapping are carried out simultaneously, avoid repeating processing, reduce production cost; Described screw tap portion is also provided with chip area 7, and this chip area extends in the shape of a spiral and runs through tapping sword, is convenient to the discharge of metal fillings by the chip area in screw tap portion; Institute's bore portion end is provided with apex point 8.
Embodiment 2
On the basis of previous embodiment 1, described clamping part and handle of a knife one-body molded, and all adopt No. 45 steel; Described handle of a knife welds with cutter head, and this cutter head adopts carbide alloy.Because cutter head adopts carbide alloy, hard alloy wear resistance, heat resistance are strong, thus ensure the wear-resisting and heat resistance of cutter head; And clamping part, handle of a knife adopt No. 45 steel, because No. 45 steel costs are low, thus reduce the production cost of spiral tap.
Embodiment 3
On the basis of previous embodiment 1, described cutter head outer surface has three layers of coating, is followed successively by titanium alloy layer undercoating 9, titanium nitride layer 10 and TiAlN external coating 11 from inside to outside.Three kinds of coatings are coated on cutter head outer surface thus cutter head outer surface is had characteristics such as hardness is high, good toughness, wearability are good, stable chemical performance, heat-resistant oxidized, coefficient of friction is little, especially firmly wait in difficult-to-machine material in cutting superelevation and can give play to outstanding performance.
