Abstract
The utility model relates to an oil pipe cutter. The oil pipe cutter is characterized by comprising a cutter body, the cutter body extends from a cutter root (3) to a cutting edge (1) through a cutter face (2), and an installing hole (4) is formed in the center of the cutter body; the cutter face (2) is a whole circle, and the thickness of the cutter face (2) is gradually increased from the cutting edge (1) to the cutter root (3). The oil pipe cutter is resistant to seizure, fracture and shocks, a notch of an oil pipe is neat, no chip exists in the cutting process, and the using requirement for cutting the oil pipe on site is met.
Description
Technical field
The utility model relates to a kind of oil pipe cutting knife.
Background technology
Oil pipe cutting knife is for cutting oil pipe device with pressure.In cutting process, oil pipe is motionless, and cutter rotates around oil pipe.In the time of oil pipe and cutting oil pipe device decentraction with pressure, use existing cutoff tool in cutting process, easily there is the problems such as swaging clamp, breaking, oil pipe otch be irregular, cannot meet on-the-spot instructions for use.And existing circular cutter is mainly used in plastic pipe and the lower thin-wall pipes cutting of hardness, be not suitable for oil pipe cutting.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of oil pipe cutting tool, to overcome the defect existing in prior art.
The technical scheme that the utility model solves is: a kind of oil pipe cutting knife, is characterized in that: comprise cutter body, described cutter body extends to blade by cutter root by knife face, and cutter body center is provided with installing hole; Described knife face is that full circle and knife face thickness are increased gradually by blade to cutter root.
Described blade, knife face, cutter root and the upper and lower symmetry of installing hole and circumference symmetry.
Described blade outer rim cross section is circular arc, and this arc radius r value is 0.6-1.2mm.
Described knife face and cutter root junction are circular arc, and this arc radius R value is 2-3.5mm.
Described knife face angle α is 18-35 o.
Described blade and cutter root thickness ratio are 1/4-1/3.
Described cutter hardness is HRC50-58.
Technique effect of the present utility model is:
The utlity model has that anti-card, anti-breaking, shatter-proof, oil pipe otch are neat, cutting process chipless, meet the instructions for use of on-site cutting oil pipe.

Fig. 1 is structure front view of the present utility model.
Fig. 2 is structure top view of the present utility model.
Fig. 3 is structure cutaway view of the present utility model.
Fig. 4 is fundamental diagram of the present utility model.
Reference numeral is:
1-blade, 2-knife face, 3-cutter root, 4-installing hole, 5-cutter, 6-quilt is cut oil pipe.
Detailed description of the invention
Referring to Fig. 1 to Fig. 4, the utility model relates to a kind of tube cutting tool, relates in particular to a kind of oil pipe cutting off tool, and its concrete structure is:
Comprise cutter body, described cutter body extends to blade 1 by cutter root 3 by knife face 2, and cutter body center is provided with installing hole 4; Described knife face 2 is that full circle and knife face 2 thickness are increased gradually by blade 1 to cutter root 3.Blade 1, knife face 2 can rotate around installing hole 4 with cutter root 3, and cutter 5 is on one side initiatively around being cut oil pipe 6 centers
orotation, on one side to the radial motion of oil pipe direction, extruding oil pipe is realized cutting, and because cutter adopts extruding cutting, chipless produces.Because the contact-making surface of cutter and oil pipe increases and increases with penetraction depth, can prevent that penetraction depth from increasing and generation swaging clamp suddenly.Cut while wearing oil pipe when cutter, cutter root contacts with oil pipe outer surface, to prevent that blade is absorbed in oil pipe swaging clamp.
Blade 1, knife face 2, cutter root 3 and installing hole in the utility model be symmetry and circumference symmetry Shang Xia 4.
Blade 1 outer rim cross section in the utility model is circular arc, and this arc radius r value is 0.6-1.2mm.Because blade 1 is arc surface, thereby the more common cutoff tool of movement locus is more level and smooth during through oil pipe irregular surface plays shatter-proof effect when cutter.
Knife face 2 in the utility model and cutter root 3 junctions are circular arc, and this arc radius R value is 2-3.5mm.
Knife face 2 angle α in the utility model are 18-35 o.
Blade 1 in the utility model and cutter root 3 thickness ratio are 1/4-1/3.
Cutter hardness of the present utility model is in HRC(50-58) between, can cut oil pipe.
The parts that the present embodiment does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
Claims (7)
1. an oil pipe cutting knife, is characterized in that: comprise cutter body, described cutter body extends to blade (1) by cutter root (3) by knife face (2), and cutter body center is provided with installing hole (4); Described knife face (2) is that full circle and knife face (2) thickness are increased gradually by blade (1) to cutter root (3).
