Description

A kind of screw tap high in machining efficiency
Technical field
The utility model is related to mechanical manufacturing field, and in particular to a kind of screw tap high in machining efficiency.
Background technology
Screw tap is one of instrument conventional in machining, is the instrument for machining internal thread, can be divided into according to shape Spiral tap and straight sword screw tap, can be divided into set tap and machine tap according to use environment, and tapping is one relatively difficult Manufacturing procedure, is cut because screw tap is almost to be embedded in workpiece, very big to the machining load of its tooth, and and workpiece Contact surface it is very big therefore higher to the intensity requirement of screw tap, and screw tap is during machining internal thread, can run into silk Cone is difficult in incision work piece, if run into hardness larger material, and incision difficulty is higher, and is easily damaged cutter.
Utility model content
The purpose of this utility model is to provide a kind of screw tap high in machining efficiency, to solve to propose in above-mentioned background technology The problem of.
To achieve the above object, the utility model provides a kind of technical scheme:A kind of screw tap high in machining efficiency, including four Prism, screw tap body, shank section, tapping portion and cutting portion, the tail end of the screw tap body are provided with quadrangular, the end of quadrangular Provided with conus portion, the middle-end of the screw tap body is provided with shank section, and the front end of shank section, which is provided with tapping portion, the tapping portion, to be set Have and chip area is provided between thread, and adjacent thread, the front end of the screw tap body is provided with cutting portion, and cutting portion is provided with cutting Sword, the positive direction of the cutting edge is provided with the preceding basil, and cutting edge is provided with the rear basil in the reverse direction.
It is preferred that, the surface of the screw tap body is provided with titanium nitride coating.
It is preferred that, the tapping portion is provided with thread provided with four straight swords, straight sword.
It is preferred that, the section of the front end in the tapping portion is trapezoidal.
It is preferred that, the cutting portion is in coniform.
It is preferred that, the both sides of the chip area at end the extension shank section, and shank section of the chip area are not provided with thread.
It is preferred that, the angle of the preceding basil is less than the angle of the rear basil.
Technique effect of the present utility model and advantage:A kind of tail end of the screw tap body of screw tap high in machining efficiency is provided with four Prism, the end of quadrangular is provided with conus portion, makes the easy for installation of screw tap, and be not in deviation, the surface of screw tap body Provided with titanium nitride coating, the intensity and wearability of screw tap are improved, service life is extended, tapping portion is provided with four straight swords, directly Sword is provided with thread, and the section of the front end in tapping portion is trapezoidal, and it is in coniform cutting portion, cutting portion that the front end of screw tap body, which is provided with, It is provided with cutting edge, the positive direction of the cutting edge is provided with the preceding basil, cutting edge is provided with the rear basil, the preceding basil in the reverse direction Angle be less than the rear basil angle, be easy to cut machined material, improve processing efficiency, at the same reduce thread be processed The direct contact of part, protects cutter to be not damaged by, also can cutting by the front end of screw tap when running into the larger material of hardness Portion's incision work piece is cut, the chip area at cutter, end the extension shank section, and shank section of chip area can be preferably protected Both sides be not provided with thread, be easy to chip removal.
