Abstract
The invention relates to an oil pipe cutter. The oil pipe cutter is characterized in that the oil pipe cutter comprises a cutter body, wherein the cuter body is formed by extending a cutter root (3) to a cutter blade (1) through a cutter face (2), an installation hole (4) is formed in the center of the cutter body, the cutter face (2) is a full circle, and the thickness of the cutter face (2) is gradually increased from the cutter blade (1) to the cutter root (3). The oil pipe cutter has the advantages of being capable of resisting clamping, preventing break, and resisting shock, incisions of oil pipes are neat, chips are absent during cutting processes, and use requirements for cutting oil pipes on site can be met.
Description
Technical field
The present invention 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.When 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.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of oil pipe cutting tool, to overcome the defect existing in prior art.
The technical scheme that the present invention 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 are symmetrical.
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 invention is:
The present invention has anti-card, anti-breaking, shatter-proof, oil pipe otch neat, cutting process chipless, meets the instructions for use of on-site cutting oil pipe.
Accompanying drawing explanation
Fig. 1 is structure front view of the present invention;
Fig. 2 is structure top view of the present invention;
Fig. 3 is structure cutaway view of the present invention;
Fig. 4 is fundamental diagram of the present invention.
Reference numeral is:
1-blade, 2-knife face, 3-cutter root, 4-installing hole, 5-cutter, 6-quilt is cut oil pipe.
The specific embodiment
Referring to Fig. 1 to Fig. 4, the present invention relates to a kind of tube cutting tool, relate in particular to a kind of oil pipe cutting off tool, 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 suddenly and swaging clamp occurs.When cutter, cut while wearing oil pipe, cutter root contacts with oil pipe outer surface, to prevent that blade is absorbed in oil pipe swaging clamp.
Knife face 2 in the present invention 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 present invention are 18-35 o.
Cutter hardness of the present invention 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).
2. oil pipe cutting knife according to claim 1, is characterized in that: the upper and lower symmetry of described blade (1), knife face (2), cutter root (3) and installing hole (4) and circumference are symmetrical.
