Abstract
The utility model discloses a kind of cutter for pipe cutting, the cutter body that comprises rounded body structure, cutter body center is provided with the axis hole with keyway, cutter body outer is circumferentially provided with a plurality of zigzag cutting edges in uniform way, cutting edge tilts along clockwise direction, and the dual-side of each cutting edge slopes inwardly and forms 70 ° of angles.The utility model is simple in structure, be easy to manufacture, easy to operate, have good practicality and security, cutter forms 55 ° of grooves by pipeline both sides inwall cutting simultaneously, makes pipe cutting and beats that groove is disposable to be completed, not only guarantee pipeline cutting quality, also can guarantee groove quality, prevent that pipe interior from being polluted, and then meet the requirement of welding to pipeline.After tested, utilize clipping time that the utility model completes a thick seamless steel pipe of 10mm only about 5 minutes, visible the utility model has not only reduced labour cost to a certain extent, and has also greatly improved operating efficiency.
Description
Technical field
The utility model relates to a kind of auxiliary cutter for pipe cutting, specifically, relates to a kind of for pipe cutting can integrated bevelled auxiliary cutter.
Background technology
At present, in pipe laying or pipe, connect in repair process, all need to before pipeline welding, cut, beat groove two procedures.Job site adopts manual gas welding cutting and sanding machine to beat groove more, specifically first utilizes cutting blade that pipeline is cut open, and then utilizes sanding machine to carry out bevel.Although this method is feasible and continue to use always, efficiency of construction is low, and groove is second-rate, also can produce heat affecting to pipeline, and welding is subsequently produced to unfavorable factor.This is that to open the whole process of cut seriously polluted to pipe interior due to manually cutting and sanding machine, and bevel angle is difficult to grasp, thereby affects welding quality.And because above-mentioned construction method is seriously polluted in pipeline, for general hydraulic pressure and cleaning inside degree, requiring high pipeline is firmly to stop to use, thereby also to pipe cutting, bring a difficult problem---can not make pipe interior contaminated because of cut-out, can not affect pipeline welding quality.
Utility model content
To be solved in the utility model is that the construction method of at present pipeline being cut and beating groove easily affects welding quality and causes the technical problem of pipe interior pollution, a kind of cutter for pipe cutting is provided, can in cutting out pipeline, form groove, can guarantee that pipe interior is not contaminated, avoid affecting pipeline welding quality.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of cutter for pipe cutting, the cutter body that comprises rounded body structure, described cutter body outer is circumferentially provided with a plurality of zigzag cutting edges in uniform way, and described cutting edge tilts along clockwise direction, and described in each, the dual-side of cutting edge slopes inwardly and forms 70 ° of angles.
Described cutter body center is provided with the axis hole with keyway.
The diameter of described cutter body is 120～140mm.
The beneficial effects of the utility model are:
Cutter structure for pipe cutting of the present utility model is simple, be easy to manufacture, easy to operate, have good practicality and security, cutter forms 55 ° of grooves by pipeline both sides inwall cutting simultaneously, makes pipe cutting and beats that groove is disposable to be completed, not only guarantee pipeline cutting quality, also can guarantee groove quality, prevent that pipe interior from being polluted, and then meet the requirement of welding to pipeline.After tested, utilize clipping time that the utility model completes a thick seamless steel pipe of 10mm only about 5 minutes, visible the utility model has not only reduced labour cost to a certain extent, and has also greatly improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of cutter that the utility model provides;
Fig. 2 is the profile of cutter that the utility model provides.
In figure: 1: cutter body; 2: cutting edge; 3: axis hole; 4: keyway.
The specific embodiment
As depicted in figs. 1 and 2, the present embodiment discloses a kind of cutter for pipe cutting, 1 rounded body structure of cutter body, and adopt hard alloy steel to make, and hard alloy steel hardness is higher, and wearability is good, can better pipe cutting and the cutter that do not wear and tear.
Cutter body 1 outer is provided with a plurality of cutting edges 2, and cutting edge 2 indentations are circumferentially uniform at cutter body 1.All cutting edges 2 tilt along clockwise direction, so cutter is in use according to cutting clockwise, can not be rotated counterclockwise.
As shown in Figure 2, the dual-side of each cutting edge 2 slopes inwardly, and forms the angle of a=70 °, can, in working angles, forming the desired 55 ° of grooves of standard in the time of along with cutting in the inwall of pipeline both sides.
Cutter body 1 is according to the tooth depth of cutting edge 2 and thickness requirement, and its diameter (comprising cutting edge 2) is controlled between 120～140mm.
Cutter body 1 center is provided with axis hole 3, and axis hole 3 band is useful on installs fixing keyway 4, so that cutter of the present utility model is installed on easily surface trimming, makes groove all-in-one and use.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that aim of the present invention and claim protect, can also make the concrete conversion of a lot of forms, within these all belong to protection domain of the present utility model.
Claims (3)
