Description
Technical field
The utility model relates to the threading tool field, is specifically related to a kind of petroleum pipeline processing and uses the screw thread blade.
Background technology
In recent years, along with the development of petroleum pipeline processing industry, to the precision of VAM screw thread, requiring of surface quality is increasingly high, and the VAM screw thread is used because of it connects firm having been obtained widely.The generally cutting completion on numerically controlled lathe of processing VAM screw thread; But in existing processing; Processing VAM screw thread exists machining accuracy and is difficult for guaranteeing that surface quality does not reach and requires and the low problem of working (machining) efficiency, the feasible needs that can't satisfy the development of petroleum pipeline processing industry.Reason is aspect screw cutting; Especially VAM screw thread; Cutting force very big (screw cutting is a processing and forming, whole shape all will participate in cutting-be the holotype cutting) unlike just point of a knife cuttings such as turnings; Make that blade damages easily, the easy cutter relieving of work piece, even lathe spindle is also had the injury of damage.And because cutting force is big, the depth of cut when making cutting is less, and working (machining) efficiency is lower.
Therefore, a kind ofly can to improve machining condition greatly, reduce cutting force, avoid product rejection and improve blade life be this area technical issues that need to address in design.
The utility model content
For solving the problems of the technologies described above, the screw thread blade is used in the petroleum pipeline processing that we have proposed a kind ofly can to improve machining condition greatly, reduce cutting force, avoid product rejection and improve blade life.
For achieving the above object, the technical scheme of the utility model is following:
The screw thread blade is used in a kind of petroleum pipeline processing, comprises cutter hub, and said cutter hub one side is provided with working face; Another relative side is provided with locating surface, and the center is provided with installing hole, and said working face is provided with the cutting teeth group that comprises roughing tooth and finishing tooth; Said finishing tooth tooth top is the smooth shape of circular arc; And suitable with the tooth form of said screw thread, the tooth top of said roughing tooth also is the smooth shape of circular arc, and less than the tooth form of said screw thread; The centre-to-centre spacing of said roughing tooth and said finishing tooth is consistent with the pitch of said screw thread.
Preferably, the quantity of said roughing tooth and said finishing tooth respectively is 1.
Preferably, said cutter hub is trapezoidal cutter hub.
Preferably, said locating surface chamfering is handled.
Pass through technique scheme; The utility model is through being provided with the cutting teeth group that comprises roughing tooth and finishing tooth at working face, said finishing tooth tooth top is the smooth shape of circular arc, and suitable with the tooth form of said screw thread; The tooth top of said roughing tooth also is the smooth shape of circular arc, and less than the tooth form of said screw thread; Because outside circle arc light slip is improved machining condition, reduce cutting force, prolong the service life of cutter simultaneously and avoided product rejection.

The numeral corresponding component title represented among the figure with letter:
1. trapezoidal cutter hub 2. working faces 21. roughing tooths 22. finishing tooths
3. tooth form 6. centre-to-centre spacing of locating surface 4. installing holes 5. screw threads
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of petroleum pipeline processing to use the screw thread blade; Its operation principle is through finishing tooth tooth top on the working face is set as the smooth shape of circular arc; And suitable with the tooth form of said screw thread, the tooth top of said roughing tooth also is set as the smooth shape of circular arc, and less than the tooth form of said screw thread; Thereby improve machining condition.
Below in conjunction with the embodiment and the specific embodiment the utility model is done further detailed explanation.
Embodiment.
Like Fig. 1, shown in Figure 2, the screw thread blade is used in a kind of petroleum pipeline processing, comprises trapezoidal cutter hub 1; Said trapezoidal cutter hub 1 one sides are provided with working face 2, and another relative side is provided with locating surface 3, and the center is provided with installing hole 4; Said working face 2 is provided with the cutting teeth group that comprises roughing tooth 21 and finishing tooth 22, and said finishing tooth 22 tooth tops are the smooth shape of circular arc, and suitable with the tooth form of said screw thread; The tooth top of said roughing tooth 21 also is the smooth shape of circular arc, and less than the tooth form 5 of said screw thread; The centre-to-centre spacing 6 of said roughing tooth 21 and said finishing tooth 22 is consistent with the pitch of said screw thread.Wherein, the quantity of said roughing tooth 21 and said finishing tooth 22 respectively is 1; Said locating surface 3 chamferings are handled.
When cutting, because the profile of tooth of roughing tooth 21 less than the tooth form 5 of screw thread, is not the holotype cutting; So the cutting force during cutting is less than the cutting force of holotype cutting; Though and finishing tooth 22 is holotype cuttings, the chipping allowance when cutting is little a lot, so cutting force is also little a lot.
The installing hole 4 that is positioned at trapezoidal cutter hub 1 center is to be contained in to locate usefulness on the knife rest, and the certain precision requirement is arranged, and guarantees that blade can only rotate after installing on the knife rest; And can't move; Limit its rotation again through the hold down gag on the knife rest, this is the current techique of this area, is not described in detail in this.
As shown in Figure 2, the centre-to-centre spacing 6 of roughing tooth 21 and finishing tooth 22 is the distances between roughing tooth 21 centers and finishing tooth 22 centers, and this distance is to be provided with according to the pitch of institute's machining screw.The screw thread that different pitch require need use different blades processing, but since the pitch kind of the used screw thread of petroleum pipeline processing industry seldom, the blade kind that needs is also few, can not bring the problem of keeping trouble to use.
For easy to make, the roughing tooth 21 and the finishing tooth 22 of the Cutting blade for machining screw thread of present embodiment respectively are provided with 1.
Also roughing tooth and the finishing tooth more than 2 or 2 can be set according to concrete processed characteristics, not do special restriction at this utility model, these equally all belong to the protection domain of the utility model.
Pass through technique scheme; The utility model is through being provided with the cutting teeth group that comprises roughing tooth 21 and finishing tooth 22 on working face 2; Said finishing tooth 22 tooth tops are the smooth shape of circular arc; And suitable with the tooth form 5 of said screw thread, the tooth top of said roughing tooth 21 also is the smooth shape of circular arc, and less than the tooth form 5 of said screw thread; Because outside circle arc light slip is improved machining condition, reduce cutting force, prolong the service life of cutter simultaneously and avoided product rejection.
To the above-mentioned explanation of disclosed a kind of petroleum pipeline processing, make this area professional and technical personnel can realize or use the utility model with screw thread blade embodiment.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
