Cylindrical cutter for cutting stainless steel pipes

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

technical field [0001] The invention relates to a pipe cutter, in particular to a cylindrical cutter for cutting stainless steel pipes. Background technique [0002] The drilling of the pipeline under pressure is completed with a cylindrical cutter. The cutting principle of the cylindrical cutter on the pipe is relatively complicated, especially when the drill piece is about to be cut off, the phenomenon of cutter jamming and knocking off the cutter head often occurs, resulting in dismantling and replacement. The cutting tool directly affects the quality and efficiency of drilling, and even once the knocked-off cutter head is stuck in the cutting groove, it needs to be replaced with a new barrel cutter. [0003] In addition, due to the special material of the thin-walled stainless steel pipe, it is difficult to cut normally. When drilling a thin-walled hole, once the drill bit breaks and shakes on one side, it is very easy to cause the knife to jam or drop the cutter head, r...

[0003] In addition, due to the special material of the thin-walled stainless steel pipe, it is difficult to cut normally. When drilling a thin-walled hole, once the drill bit breaks and shakes on one side, it is very easy to cause the knife to jam or drop the cutter head, resulting in the opening of the hole. job failure
