Abstract
The invention discloses a rotary pipe cutter. The rotary pipe cutter is characterized by comprising a blade base (5) and a bearing roller base (8) that are connected with each other by a bolt (1) and a nut (2); a blade (3) is fixed on the blade base (5) by a blade pin (4); two bearing rollers (6) are fixed on the bearing roller base (8) respectively by roller pins (7); the blade base (5) and the bearing roller base (8) are provided with a crowbar jack (9) respectively; and the rotary pipe cutter has novel design and compact structure, is especially applicable to the pipeline cutting and reconstructing of narrow regions in site, has aligned incision, is suitable for reunion of pipelines, does not generate sundries that enter the pipelines, can carry out the clamping and cutting operation without needing the pipeline with the end surface, and has greater application value and popularization value.
Description
Technical field:
Patent of the present invention relates to a kind of pipe cutting cutter field of mechanical technique, is a kind of rotary pipe cutter specifically.
Background technology:
At present, when home and abroad enterprise transforms fluid pressure line, generally adopt following three kinds of modes: first kind original pipeline removed from the slip-knot junction, move on to spacious place and use special-purpose cutter cutting, shortcoming is if pipeline is oversize, then is difficult for maybe can't shifting out; Second kind is to treat the on-the-spot electricity consumption gas welding of transformation place at original pipeline, and shortcoming is that section is not concordant, increased the difficulty of welding again, and slag enters easily in the pipeline; The third is to treat that at original pipeline transformation place scene cuts with cutting machine, and shortcoming is that the cutting iron filings easily enter in the pipeline.Also have and adopt other cutter, there is following limitation in it: 1. general pipe cutting cutter can not be used for on-the-spot pipeline cutting; 2. most pipe cutting cutters can not be used for the cutting of narrow zone pipeline; 3. certain danger is arranged when using electronic cutting tool that the narrow zone pipeline is cut; 4. general pipe cutting cutter must be inserted in pipeline from the pipeline end face, can't not use cutting if pipeline has end face.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of rotary pipe cutter is provided, mainly solving existing pipeline cutting tool sometimes can not on-site cutting, section is not concordant, can not be used for the cutting of narrow zone pipeline, poor stability and for no reason the facial canal road problem such as can't cut.
In order to achieve the above object, the present invention is achieved in that rotary pipe cutter, its special character is that it comprises blade bearing and supporting roller base, the two is connected by screw bolt and nut, blade is fixed on the blade bearing by the blade pin, 2 backing rolls are established the crowbar jack respectively by being fixed on the supporting roller base by the roller pin respectively on blade bearing and supporting roller base.
Rotary pipe cutter of the present invention, the crowbar jack on its described blade bearing and the supporting roller base is respectively a plurality of.
Compared with the prior art rotary pipe cutter of the present invention has outstanding substantive distinguishing features and marked improvement, and 1, can directly cut at the scene to pipeline; 2, can be used for the cutting of narrow zone pipeline; 3, the otch section is concordant; 4, solved the problem that slag or iron filings enter pipeline; 5, because adopt split typely, can pipe cutter be enclosed within on the pipeline from the optional position of pipeline during use, break through the limitation that other pipe cutter must be inserted in from the pipeline end face; 6, can be used for the cutting of hydraulic pressure, water, gas (vapour) pipeline, applied widely; 7, be fit to the cutting of different tube diameters pipeline, also can make series of products.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe rotary pipe cutter of the present invention in detail.
Rotary pipe cutter of the present invention, during work, unclamp nut, rotary pipe cutter is enclosed within the corresponding position of transforming pipeline, clamp nut makes blade, 2 backing roll three-point fixs carry out centering to pipe then, clamp nut control feed, again crowbar is inserted rotary cutter in the crowbar jack, finish the cutting of a circle pipe; Carry out with this, until pipe is cut off.
Claims (2)
1. rotary pipe cutter, it is characterized in that it comprises blade bearing (5) and supporting roller base (8), the two is connected with nut (2) by bolt (1), blade (3) is fixed on the blade bearing (5) by blade pin (4), 2 backing rolls (6) are established crowbar jack (9) by being fixed on the supporting roller base (8) by roller pin (7) respectively respectively on blade bearing (5) and supporting roller base (8).
2. rotary pipe cutter according to claim 1 is characterized in that the crowbar jack (9) on described blade bearing (5) and the supporting roller base (8) is respectively a plurality of.
