The utility model discloses the technical problem that will solve can also realize through following technical scheme that the slope of first groove is greater than the slope of second groove.

The utility model discloses the technical problem that will solve can also be realized through following technical scheme, and the contained angle between first groove and the cutter body cutting part is 60.

The utility model discloses the technical problem that will solve can also be realized through following technical scheme, is the V type setting between first groove and the second groove, and V type angle is greater than 90.

The utility model discloses the technical problem that will solve can also be realized through following technical scheme, and the contained angle that first groove and second groove become is 15.

The utility model discloses the technical problem that will solve can also realize through following technical scheme, adopts the fillet level and smooth to meet between first groove and the second groove.

The technical problem to be solved by the utility model can also be realized by the following technical scheme, and the fillet radius between the first groove and the second groove is 0.02-0.04mm.

Compared with the prior art, the cutter has solved prior art in the cutter can only dig single groove, the technical problem of change cutter through establishing the double groove that comprises first groove and second groove, the utility model discloses a double groove cutter participates in simultaneously and digs the limit, has reduced the single groove atress of cutter, has reduced the wearing and tearing of cutter, has prolonged the cutter life-span, has promoted machining efficiency.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-3, a double-bevel cutter for SAW steel pipe edge planing is provided with a cutter body 1, a positioning hole 2 extending from the edge of the cutter body to the back is arranged in the middle of the cutter body 1, a first bevel 3 and a second bevel 4 with different slopes are arranged at the end part of the cutter body, one end of the first bevel 3 is connected with the edge of the cutter body 1, the other end of the first bevel 3 is connected with one end of the second bevel 4, the other end of the second bevel 4 is connected with the back of the cutter body, the slope of the first bevel 3 is greater than that of the second bevel 4, the angle between the first bevel 3 and the edge of the cutter body 1 is 120 degrees, and the cutter body is a hexagonal cutter body when viewed from the side of the cutter body, the side length of the blade part of the cutter body is smaller than that of the back part of the cutter body, double grooves formed by a first groove and a second groove are arranged between the two ends of the blade part and the two ends of the back part, the double grooves at the two ends of the cutter body are symmetrically arranged relative to the positioning hole, namely the short edge of the cutter body is connected with the first groove, the included angle formed by the short edge of the cutter body and the first groove is 60 degrees, the first groove 3 and the second groove 4 are arranged in a V shape, the V-shaped angle is larger than 90 degrees, the angle formed by the first groove 3 and the second groove 4 is 165 degrees, the included angle formed by the first groove 3 and the second groove 4 is 15 degrees, the first groove 3 and the second groove 4 are smoothly connected by a fillet, and the fillet radius between the first groove 3 and the second groove 4 is 0.02-0.04mm.
