Abstract
The utility model discloses a rotation type pipe cutting machine, it includes two knife rests, is fixed with two blades on the knife rest, still is provided with two pipeline grapples, only is fixed with two blades on another knife rest, two knife rests pass through bolt for tool post and the connection of feed nut, carry out cutting work through operating handle, the pipeline grapple passes through pipeline grapple round pin axle and torsion spring connect on the knife rest, it is that connection and knife rest separable from are placed that operating handle and knife rest are the grafting, the pipeline grapple is fixed on the knife rest, is provided with the torsional spring on the pipeline grapple, can open gradually along with the feeding of feed nut, and then fixed pipeline, two blades above the release cut pipelines. The beneficial effects of the utility model are that: pipeline grapple and collet can be steadily fixed pipeline, guaranteed cutting plane level and smooth no burr in cutting process of pipeline, the required space of pipeline cutting is unrestricted, and the operation is light convenient, and cutting speed is fast.
Description
Technical field
The utility model relates to a kind of pipe cutting machine be applied on gas pipeline, particularly a kind of rotary pipe cutting machine.
Background technology
In the cutting of present gas pipeline, general employing nitrogen displacer gas, carries out the mode of gas welding welding.But there is the risk of blast in the lancing of gas pipeline band; The simultaneously more coarse and out-of-flatness of the otch of gas welding welding, and chip not easy-clear, remain in gas pipeline.
Summary of the invention
The purpose of this utility model is the deficiency in order to solve the problem, and provides a kind of simple to operation, rotary pipe cutting machine that security is high.
The technical scheme in the invention for solving the technical problem is: a kind of rotary pipe cutting machine, comprise operating grip, knife rest, pipeline grapple and feed nut, it is characterized in that: described knife rest is fixed two blades, described blade passes through blade pinned connection on knife rest; Described pipeline grapple is connected on knife rest by pipeline grapple bearing pin and torsion spring; Described feed nut connects two knife rests by bolt for tool post; Described operating grip connects knife rest by the mode of grafting.
Described operating grip and knife rest are socket connections, and knife rest can be separated.
Described feed nut connects upper and lower two knife rests, makes the gradual cutting pipeline of blade.
Described pipeline grapple is fixed on knife rest, and pipeline grapple is provided with torsion spring, can open gradually along with feeding of feed nut, and then fixed-piping, release two blade cuts pipelines above.
The beneficial effects of the utility model are: pipeline grapple and collet can fixed-pipings steadily, ensure that the cut surface of pipeline level and smooth impulse-free robustness in cutting process; Pipe cutting requisite space is unrestricted, and it is easily convenient to operate, and cutting speed is fast; Pipeline in cutting process without chip, without any spark, safe and reliable.For inflammable and explosive, forbid the medium place of noise, narrow space and water.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing with specific embodiment, the present invention is further described.
A kind of rotary pipe cutting machine, as shown in Figure 1, comprise operating grip 1, knife rest 2, pipeline grapple 3 and feed nut 7, described knife rest 2 is fixed two blades 8, described blade 8 is connected on knife rest 2 by blade bearing pin 9; Described pipeline grapple 3 is connected on knife rest 2 by pipeline grapple bearing pin 5 and torsion spring 4; Described feed nut 7 connects two knife rests 2 by bolt for tool post 6; Described operating grip 1 connects knife rest 2 by the mode of grafting.
The course of work of rotary pipe cutting machine, knife rest 2 is opened by described rotation feed nut 7, pipe laying, by rotating feed nut 7 in the other direction, fixed-piping, continue to rotate feed nut 7, make pipeline grab pipe 3 to rotate, discharge blade 2, make rotary pipe cutting machine tightly fix pipeline, by operating grip 1, rotary pipe cutting machine is rotated on pipeline again, until cut the object of pipeline completely.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process with this, and the equivalence namely done according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
