Abstract
Disclosed is a thread cutting tool. A thread cutting tool region is arranged at one end of a cutting tool body, and a threaded section of a work-piece is cut in the thread cutting tool region which is adjacent to at least one chip removal guide groove. The at least one chip removal guide groove is used for guiding and discharging chips of the work-piece, which is produced by cutting of the thread cutting tool region. A leading-in cutting portion is arranged at a first thread position, which is corresponding to the threaded section of the cut work-piece on the rear side of the thread cutting tool region along the axial direction of the cutting tool. A cutting action region formed by a front cutter face on the leading-in cutting portion is used for removing the first thread of the work-piece, and certain inclined angle is formed between the front cutter face and the horizontal direction. By means of the thread cutting tool, threads can be cut through one step, the work-piece and a fit part can be locked and led in easily, and accordingly, deformation and cracking of threads and cutting of workers can be prevented effectively.
Description
Technical field
The present invention relates to a kind of cutter, especially the cutter of screw cutting.
Background technology
The threaded workpiece of general tool, first thread (namely importing thread) of its thread segment is normally sharp and thin, not only be easy to the hand hurting staff, also be easy to produce because of small collision burst apart simultaneously, so that enter into it and counterpart is sealed time, have some setbacks cautious or cannot be sealed, first thread of double thread section carries out necessary excision for this reason, on the one hand except can facilitating sealed importing, the hand hurting staff can be prevented again on the other hand, and its procedure of processing as shown in Figure 1, first with the cutter 11 of a screw cutting, its thread cutting tool district is utilized to carry out the processing of screw cutting to workpiece 10, after the cutting completing thread segment 100 again with another cutter 12 excise the first thread 101 of this thread segment 100 part or all (normally the first thread 101 is done l/2 circle to 2/3 circle excision, but the maximum shortcoming of this kind of processing mode is exactly to utilize two different cutters, outside not only very inconvenient in processing, also very uneconomical on cost.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned defect, provides a kind of cutter that once can complete screw cutting and do to import thread process.
For the technical scheme solving the problems of the technologies described above employing is: a kind of cutter of screw cutting, a thread cutting tool district is provided with in one end of a cutter body, the thread segment of a workpiece is cut in this thread cutting tool district, and this thread cutting tool district adjoins at least one chip removal guide groove, the detritus that this workpiece is cut in this thread cutting tool district is discharged in order to guiding, the rear side in this thread cutting tool district is along the first thread position of the thread segment of its machining part axially corresponding of this cutter, be provided with an importing cutting portion, the shear action district formed by a rake face in this importing cutting portion is in order to excise the first thread of this workpiece, this rake face and horizontal direction are an angle of inclination.
This thread cutting tool district comprises at least one threading tool.
This beneficial effect of the invention is: once can complete screw cutting, and workpiece easily and the sealed importing of counterpart, can effectively prevent deformed threads, burst apart and hurt staff.

Detailed description of the invention
As shown in the second to five figure, a thread cutting tool district 21 is provided with in one end of its body 20 of cutter 2, this thread cutting tool district 21 is made up of at least one threading tool 211, in order to cut a workpiece 3(as shown in the 6th figure) thread segment 31 (can be internal thread or external screw thread), and this thread cutting tool district 21 adjoins at least one chip removal guide groove 22, detritus when this workpiece 3 is cut in this thread cutting tool district 21 is discharged in order to guiding, the rear side in this thread cutting tool district 21 and correspond to first thread 310 position of the thread segment 3l of its machining part 3 along the axis of this cutter 2, be provided with an importing cutting portion 23, this importing cutting portion 23 forms shear action district by a rake face 231, this rake face 231 is an angle of inclination Q1 (its angle is about 3 ~ 5 °) with horizontal direction, to form a machinable blade.The distance of the axial centre O of the thread cutting tool district 2l of this creation and this both importing cutting portion 23 distance cutter 2, be respectively the first distance L1, second distance L2 (as the drawing), the range difference D of the two is about 0.3m/m (this range difference D is depending on workpiece), so will the degree of depth of importing cutting portion 23 machining part 3 be greater than at the bottom of the tooth of this thread segment 21, make its thread segment 21 of workpiece 3 more easy with the sealed importing of accessory.As shown in the 6th figure, when this creation is cut workpiece 3, cutter 2 first carries out the cutting of thread segment 31 with its thread cutting tool district 2l, thread cutting tool district 21 is when cutting last thread 312, and this importing cutting portion 23 carries out the removal cutting of the first thread 310 just.This cutting can remove this first thread 310 part or all (desirable removal be the first thread 310 1/2 circle ~ 2/3 circle, this is that the demand of looking workpiece 3 determines completely), form a desirable introducing port 311 after removing, this will contribute to the removal of the sealed importing of thread segment 31 and the first thread 310.
