Abstract
The invention discloses a guiding compound cutting screw tap based on different diameters, and the guiding compound cutting screw tap comprises a screw blade body and a screw handle, wherein the screw blade body and the screw handle are integrally formed; a plurality of screw blade strips are integrally arranged on the screw blade body; and a screw blade face is arranged in the front of each screw blade strip. The guiding compound cutting screw tap is characterized in that the screw bottom diameter of a first cutting screw blade at the chamfer of each screw blade strip is less than the those of other cutting screw blades; and the screw bottom diameter of the first cutting screw blade is not in the same line with the connection line of other screw bottoms. By using the technical scheme of the invention, the wear-resisting property of the screw tap can be enhanced, the service life can be prolonged, the screw tap can be subjected to high-intensity processing for a long time by utilizing the optimization manner, and the processing quality is increased.
Description
Technical field
The present invention relates to a kind of screw tap, relate to a kind of guide-localization screw tap specifically, the technical program is used for the silk hole processing of machining to workpiece.
Background technology
At present, spiral tap that uses in the machining or straight trough screw tap are by the silk sword, chamfering, chamfering blades, the silk handle constitutes, the silk sword, the cutting edge face of chamfering blades is roughly on a plane or same helicoid, the silk end line of each sword bar is roughly on straight line or helix, distance is too small not to have a guide-localization effect because chamfering place silk pushes up at the bottom of the silk, tapping has as a result become reaming, cause workpiece to scrap, and, because the silk sword face of each group is formed by single, silk sword easy fracture then when angle is too sharp keen between silk sword face and the silk top, occur the silk handle when angle is excessive between silk sword face and the silk top and clamp that Tool Room torsion is excessive easily to cause the whole fracture of screw tap, in workpiece, cause workpiece quality impaired even scrap.
Summary of the invention
The present invention is exactly in view of the above-mentioned problems and proposes, so that a kind of novel branch combined cut screw tap that directly leads to be provided, this kind screw tap is located easily, the radiating efficiency height, wear-resistant, the life-span is long.
In order to achieve the above object, the present invention adopts following technical proposals:
Optimized technical scheme 2, on above-mentioned branch directly leads combined cut screw tap basis, at the bottom of each sword bar chamfering place and near a plurality of sword silks thereof diameter less than other sword silks at the bottom of diameter, and with line at the bottom of other not on straight line or helix.
Optimized technical scheme 3, at the above sword face of the basis of technical scheme 1 or 2 to forming a platform between the screw tap bottom land.
Optimized technical scheme 4, the silk sword face of silk sword is left a little silk sword face near each sword bar chamfering on the basis of technical scheme 1 or 2 reaches, all the other silk sword faces near silk shank silk sword are precursor sword face, and little silk sword face and the silk concentrically ringed angle a in cutting edge place, top are greater than precursor sword face and the silk concentrically ringed angle b in cutting edge place, top.
Optimized technical scheme 5, on the basis of technical scheme 1 or 3, described silk sword body is a kind of in the following type: tapering silk sword body, raw silk rings sword body, taenidium sword body.
Beneficial effect: since the silk end diameter that the present invention has adopted each sword bar chamfering place first cutting silk sword less than other cutting silk sword silks at the bottom of diameter, and with the technical characterictic point-blank not of line at the bottom of other, make screw tap easier location when work at the bottom of the first cutting silk sword silk; Little sword face of main stress part strengthened scuff resistance in the processing owing to an angle b technical characterictic that has adopted a little silk sword face and an angle a that pushes up greater than precursor sword face and silk top makes, also be not easy to make its whole fracture, prolong the life-span, and in process, kept high strength always.

The specific embodiment
Technical scheme and preferred implementation thereof below in conjunction with the detailed explanation compound cutting face screw processing tool of the present invention of accompanying drawing.
As shown in Figure 1, this branch footpath combined cut screw tap that leads comprises a sword body 1 and a silk handle 2, this sword body 1 and silk handle 2 form as one, silk sword body 1 one be provided with a plurality of sword bars 3, there is a silk sword face front of each sword bar, the silk end diameter of chamfering 4 places first cutting silk sword less than other cutting silk sword silks at the bottom of at the bottom of diameter and the first cutting silk sword silk with line at the bottom of other not on straight line or helix.
As shown in Figure 2, on the basis of embodiment 1 structure, on above-mentioned branch directly leads combined cut screw tap basis, at the bottom of chamfering 4 places and near a plurality of sword silks thereof diameter less than other sword silks at the bottom of diameter, and with line at the bottom of other not point-blank.
As shown in Figure 3, on the basis of embodiment 1 structure, silk sword face is to forming a platform 8 between the screw tap bottom land.
As shown in Figure 3, on the basis of embodiment 1 structure, the silk sword face of silk sword bar 3 chamferings, 4 places and near silk sword bar is left a little silk sword face 5, silk sword face near 2 silk swords of silk handle bar is a precursor sword face 6, and little silk sword face 5 and the silk top concentrically ringed angle a in 7 cutting edge places are greater than precursor sword face 6 and the silk top concentrically ringed angle b in 7 cutting edge places.
Above embodiment only be the technical program preferred embodiment; certainly the technical program also has other embodiment; present specification is enumerated no longer one by one, and the specific embodiment that claim of the present invention limited and derivative schemes thereof all fall into protection scope of the present invention.
