Abstract
The utility model discloses a hard alloy extrusion tap comprising a handle axially jointed through opposite end surfaces and a hard alloy tapping head unit provided with a tap rod, wherein, opposite jointing ends are provided with coordination end tooth structures which can be mutually meshed, and the coordination end tooth structures are mutually jointed through a fastening structure. The hard alloy extrusion tap with the structural style can greatly improve the service life and the efficiency of the tap, is not easy to be broken during the production, can be replaced after the tap becomes blunt, saves the materials, and decreases the product cost.
Description
Technical field
The utility model relates to the carbide alloy thread forming tap structure of a kind of screw tool, particularly a kind of machining internal thread.
Background technology
In field of machining, be to carry out at present mostly with screw tap to the processing of internal thread.But with general screw tap machining screw, precision is not high, and the screw tap life-span is low, efficient is low.Recently the existing high-speed steel hard alloy thread forming tap that adopts on life-span, precision and efficient large increase has been arranged, but its service life, machining accuracy and efficient etc. does not reach well-content degree as yet.
The utility model content
At above-mentioned situation, the utility model will provide a kind of carbide alloy extrusion pressing type screw tap structure of improving structure, to improve its service life and efficient.
The structure of the utility model carbide alloy thread forming tap, include vertically with the opposing end surface shank that engages and the carbide alloy screw tap head unit two parts that have the screw tap bar, be provided with the intermeshing abutting end toothing of energy in its relative engagement end portion, and be bonded with each other through fastening structure.Wherein, said this fastening structure, best mode is to adopt a kind of outer face by carbide alloy screw tap head to run through and extend to the bolt structure spare of shank vertically.
In said structure, the said said abutting end toothing that is arranged at shank and the setting of carbide alloy screw tap head unit engagement end portion can be 2～15 generally speaking.Guaranteeing to realize under the situation of positive engagement that this end tooth structure number at its both ends is all best with maintenance mutually.
The diametric plane angle of the said abutting end toothing that said shank and carbide alloy screw tap head unit engagement end portion are provided with in the above-mentioned carbide alloy thread forming tap structure is generally chosen all in 5 °～70 ° scopes and is fine.
Between the said abutting end toothing of said shank and the setting of carbide alloy screw tap head unit engagement end portion, it is further had extend the coadapted axial cooperation of energy inclined-plane in the axial direction, and/or make and close the end tooth structure and have radially entad angle, and its abutting end toothing radially and/or maintain suitable biting between axial tooth top tooth root matching part and close the gap, the self-centering capability that all can help making the axis of the axis of carbide alloy screw tap head unit and screw tap bar to overlap automatically, convenient for assembly and guarantee and the raising assembly precision.
Test shows, the carbide alloy thread forming tap of the utility model said structure form can improve the service life and the efficient of screw tap greatly, frangibility not aborning, and, saved material with changeing after blunt, reduced product cost.
Below in conjunction with the specific embodiment, foregoing of the present utility model is described in further detail again by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.

Fig. 2 is the schematic diagram of the axial sectional structure of a kind of carbide alloy screw tap head unit in Fig. 1 carbide alloy thread forming tap.
Fig. 3 is the end face structure view of the carbide alloy screw tap head unit of Fig. 2.
Fig. 4 is the screw tap shank of Fig. 1 and the A-A radial section state partial schematic diagram at carbide alloy screw tap head unit engagement position.
The specific embodiment
The utility model carbide alloy thread forming tap as shown in the figure, its structure includes vertically shank 1 that engages with opposing end surface and carbide alloy screw tap head unit 2 two parts that have the screw tap bar, runs through and extend to screw or other similar fastening structure 3 mutual close and firm joints of shank 1 therebetween vertically via the outer face of carbide alloy screw tap head 2.In the relative bonding end of shank 1 and carbide alloy screw tap head unit 2, be respectively arranged with 2～15 intermeshing abutting end toothings 4,5 of energy.The angle of this abutting end toothing 4,5 can be selected in 5 °～70 ° scopes, and respectively it all has entad angle radially respectively, and has the coadapted axial cooperation of extension energy inclined-plane in the axial direction.This abutting end toothing 4 in this shank 1 and carbide alloy screw tap head unit 2 engagement end portion, also all maintaining suitable biting closes gap 6 between radially tooth top-tooth root matching part of 5, between its axial tooth top-tooth root matching part, also all maintain suitable biting and close the gap, can have the automatic self-centering capability that overlaps with the axis of screw tap bar with the axis that helps carbide alloy screw tap head unit.
