Abstract

The invention provides a cylindrical cutter for cutting stainless steel pipes. The cylindrical cutter comprises a hollow cylindrical cutter body, the upper periphery of the cylindrical cutter body is of a tooth-shaped structure, a cutter bit is arranged on the tooth-shaped structure of the cylindrical cutter body, and a blade of the cutter bit comprises a main front blade and an inclined blade, wherein the inclination angle of the main front blade is 35 degrees, the gradient of the inclined blade is 45 degrees, and the cutter bit is made of tungsten and cobalt. According to the invention, the cutter is of a cylindrical structure, the stainless steel pipes can be cut through the cutter bit on the tooth-shaped structure, the cutter bit is formed by combining the main front blade and the inclined blade, so that the hidden danger of shaking during the hole formation process of the stainless steel pipes is eliminated, and the phenomenon that the cutter gets jammed is avoided.

Description

A kind of Cylinder shape cutter for the pipe that cuts stainless steel
Technical field
The present invention relates to a kind of pipeline cutter, particularly relate to a kind of Cylinder shape cutter for the pipe that cuts stainless steel.
Background technology
Drilling under pressure of pipeline adopts Cylinder shape cutter to complete, Cylinder shape cutter perforate cutting principle on pipeline is comparatively complicated, especially swaging clamp and the phenomenon of destroying cutter head is often there is when being about to open brill sheet, cause the machine of tearing open, change cutter, directly affects quality and the efficiency of perforate, even once the cutter head destroyed is stuck in bite groove, just need the cylinder cutter more renewed.
In addition, due to the material particularity of thin-wall stainless steel, normal cutting is difficult, when carrying out thin-walled perforate, once bore sheet to occur monolateral disconnection jitter conditions, very easily causing swaging clamp or falling cutter head situation, causing perforate work failure.
Summary of the invention
The present invention is directed to deficiency of the prior art and provide a kind of Cylinder shape cutter for the pipe that cuts stainless steel, this cutter is tubular construction, solves a boring difficult problem for stainless steel tube.
For solving the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of Cylinder shape cutter for the pipe that cuts stainless steel, it is characterized in that, comprise hollow cylindrical barrel cutter hub, described cylinder cutter hub last week is tooth-shape structure, the tooth-shape structure of described cylinder cutter hub is provided with cutter head, described cutter head blade comprises main front edge and oblique sword, and the gradient of described main front edge is 35 degree, and the gradient of described oblique sword is 45 degree.
For improving cutter head toughness, described cutter head is tungsten cobalt material.
Beneficial effect of the present invention and advantage are: cutter of the present invention adopts tubular construction, can to be cut stainless steel tubing by the cutter head on tooth-shape structure, cutter head, by the combination of main front edge and oblique sword two kinds of blades, eliminates shake hidden danger during stainless steel tube perforate, avoids swaging clamp phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Shown by reference numeral: 1-cylinder cutter hub, 2-cutter head, 21-main front edge, 22-tiltedly sword, 3-body.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
As shown in Figure 1, a kind of Cylinder shape cutter for the pipe that cuts stainless steel, comprise hollow cylindrical barrel cutter hub 1, cylinder cutter hub 1 last week is tooth-shape structure, the tooth-shape structure of cylinder cutter hub 1 is provided with cutter head 2, and cutter head 2 blade comprises main front edge 21 and oblique sword 22, and the gradient of main front edge 21 is 35 degree, the gradient of oblique sword 22 is 45 degree, and cutter head 2 is tungsten cobalt material.
During use, inserted by body 3 in the tooth-shape structure of a cutter hub 1, main front edge 21 first will be bored sheet and body 3 and be cut by point of a knife herein, and oblique sword 22 remains stable cutting force, and main front edge 21 eliminates the shake of perforate after cutting, and oblique sword 22 can feed brill be saturating smoothly.
