Abstract
The utility model relates to a cutter, in particular to a cutter for cutting a pipe groove. A transition surface is arranged between a front cutter surface and a rear cutter surface of the cutter, which makes the included angle between the front cutter surface of the cutter and the transition surface larger than the original included angle between the front cutter surface and the rear cutter surface of the cutter, and increases the cutting force bearing surface of a blade of the cutter with the enhancement of the cutting force of the blade for cutting a pipe. The cutter is simple in structure and high in operating efficiency, and is not prone to blade damage.
Description
Technical field:
The utility model relates to a kind of cutter, relates in particular to a kind of cutter that cuts tube groove.
Background technology:
In the construction of natural gas fields of high sulfur-bearing gas reservoir was carried, hydrogen sulfide was wayward, needed anti-naked light, anti-high temperature, avoided taking place security incident.In pipeline welding process, adopt welding-cutting machine to cut pipeline at present more.With low cost, easy to operate, advantages such as cut quality is good, operating rate is fast, convenient transportation, environmental protection that welding-cutting machine has.Adopt welding-cutting machine to cut pipeline, do not meet safety requirements, can only adopt the method cutting pipeline of machining.Existing cutting tool design has point of a knife, because pipeline is its intensity height of carbon steel, cutter point of a knife place is stressed irregular in the cutting process, very easily fracture, and operating efficiency reduces greatly, and workman's amount of labour strengthens greatly.
Summary of the invention:
The purpose of this utility model just provides a kind of cutter, can effectively prevent cracking of cutter, improves cutter life.
The technical scheme that the utility model provides is:
A kind of anti-H 2 S carbon steel piping groove tool is provided with a transition face between the rake face of cutter and the back knife face.
Transition face is smooth surface or plane.
The front portion of the rake face of cutter is provided with dregs guiding groove.
The utility model is simple in structure, and high efficiency has been saved point of a knife, has strengthened the cutting force of blade cutting pipeline, not fragile blade.The rake face of the utility model cutter and the angle between the transition face are greater than the rake face of original cutter and the angle between the knife face of back, and the bearing plane of cutter blade cutting force increases like this, have improved the cutting force of cutter cutting pipeline.
Description of drawings:
Fig. 1 the utility model structural representation
1 cutter, 2 rake faces, 3 dregs guiding grooves, 4 transition faces, 5 back knife faces.
The specific embodiment:
As shown in Figure 3, cutter 1 of the present utility model is provided with rake face 2 and back knife face 5, between the rake face 2 of cutter 1 and back knife face 5 transition face 4 is set.Transition face is a smooth surface.Also can be the plane.The front portion of cutter 1 is provided with dregs guiding groove 3.
Claims (3)
1. an anti-H 2 S carbon steel piping groove tool is characterized in that: between the rake face of cutter and the back knife face transition face is set.
2. according to the described a kind of anti-H 2 S carbon steel piping groove tool of claim 1, it is characterized in that: transition face is smooth surface or plane.
3. according to claim 1 or 2 described a kind of anti-H 2 S carbon steel piping groove tools, it is characterized in that: the front portion of the rake face of cutter is provided with dregs guiding groove.
