Description
Technical field
The utility model relates to a kind of cutter sweep, is specifically related to the artificial cutter sweep of a kind of improved polyfluortetraethylene pipe.
Background technology
Polyfluortetraethylene pipe has a wide range of applications in corrosive fluid transfer pipeline.In this class application, polyfluortetraethylene pipe need to first cut into fixed length, then is set with metal tube.But existing polyfluortetraethylene pipe is in manpower cutting process, need first the engaging of polyfluortetraethylene pipe outer wall, and according to cutoff length location, then with hand pin polyfluortetraethylene pipe on one side, another side cuts, production efficiency is low, has greatly wasted manpower.In addition, in the time cutting, teflon hose, because the downward active force that cutting knife applies can deform, causes otch out-of-flatness.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provide a kind of can human-saving and can improve the polyfluortetraethylene pipe cutter sweep of otch planarization.
For this reason, the technical solution of the utility model is the artificial cutter sweep of a kind of improved polyfluortetraethylene pipe, and it comprises workbench, and workbench is provided with base, and a side of base is connected with one end of the locating shaft for wearing polyfluortetraethylene pipe, is stiff end; The central axis along continuous straight runs of locating shaft arranges, and the length of locating shaft equates with the cutoff length of polyfluortetraethylene pipe; The other end of locating shaft is free end, and free-ended end face is vertical plane; The workbench of free end is provided with snap fastener, snap fastener comprises upper fastener, lower fastener and locking mechanism, lower fastener is positioned at the below of locating shaft, upper fastener is positioned at the top of locating shaft, and upper and lower fastener can folding, by locking mechanism lock form can snare locating shaft free-ended ring packing structure, and the inner surface of ring packing structure and the outer surface of polyfluortetraethylene pipe suitable, its right end face of ring packing structure is equal with described free-ended end face; The right side of snap fastener is provided with cutting knife, its right end face of the left surface laminating snap fastener of cutting knife, and the cutter peak of cutting knife arranges down, and one end of the knife back is provided with handle, and the other end of the knife back is rotationally connected with tool rest, and tool rest is fixed on workbench.
When use, locating shaft makes the inwall of polyfluortetraethylene pipe limited, and base makes the length direction of polyfluortetraethylene pipe limited, snap fastener makes the outer wall of polyfluortetraethylene pipe limited, while cutting, operator, without pressing polyfluortetraethylene pipe with hand again, more saves manpower; Because locating shaft and snap fastener make respectively the inside and outside wall of polyfluortetraethylene pipe limited, support polyfluortetraethylene pipe with larger contact area, while having avoided cutting, polyfluortetraethylene pipe distortion causes otch out-of-flatness.
For simplified structure, preferably, described upper and lower fastener one end is hinged, other end folding; The each protruding projection that is provided with in one end of described upper and lower fastener folding, is respectively upper and lower projection, and the lower surface of projection and the upper surface of lower convexity fit, and form cylindrical outline, and the upper and lower protruding outer surface of laminating is provided with screw thread; Described locking mechanism is and the nut of described threaded engagement.
In order not damage poly-cubic ethylene tube outer wall, preferably, the inner surface of described upper and lower fastener is also provided with elastomeric pad.
In order to improve the flexibility of this cutter sweep, preferably, described locating shaft and described base are for removably connecting; The position of described base on described workbench is adjustable.Like this, in the time that needs change cutoff length, only need to change the locating shaft of corresponding length, and adjust the position of base on workbench, make the free-ended end face of its right end face, locating shaft of snap fastener equal, and the left surface of the cutting knife of fitting, like this, this cutter sweep can adapt to different length batch polyfluortetraethylene pipe cut requirement.
Locating shaft is often subject to active force vertically in the process that wears polyfluortetraethylene pipe.In order to improve the firm position of locating shaft, preferably, described locating shaft with described base for being threaded.The axial force that locating shaft is subject to so can not affect the connectivity robustness of itself and base, and then the free end end face of the locating shaft ensureing keeps good vertical state, thereby has improved the planarization of polyfluortetraethylene pipe otch.
Described base with the connected mode of described workbench can be: described workbench is provided with the slide rail coordinating with base basal sliding, and a side relative with base of slide rail is provided with holder; Holder and base are provided with corresponding through hole, and fastening bolt coordinates with nut through holder, base.
Advantage of the present utility model and beneficial effect are: the artificial cutter sweep human-saving of this improved polyfluortetraethylene pipe, otch are smooth, and also have advantages of that flexibility is good.
