Abstract
The utility model relates to the technical field of pipe products, in particular to a broach for eliminating burrs on the inner surface of a long pipe fitting. The broach comprises a broach shaft core, an expansion sleeve fixed outside the broach shaft core, a broach blade arranged on the outer portion of the expansion sleeve, and a check ring used for limiting the broach blade. The overall broach is arranged in the pipe fitting, and the broach blade is perpendicular to the broach shaft core. The broach is simple in structure, and is driven by a driver to penetrate through the inner diameter of the long pipe fitting, due to the fact that the overall size of the broach can be changed, in the working process, the broach does not need to be dismounted, and is convenient to use, and high in efficiency.
Description
Technical field
The utility model relates to the technical field of tubing, more specifically, relates to long pipe fittings inner surface and removes burr broaching tool.
Background technology
Current domestic long pipe fittings inner surface is removed burr, and plucking thorn starts all broaching tool to be loaded onto from other one end of pipe fitting, takes again broaching tool apart and pass to other one end and load onto after pulling.This process, the efficiency of work reduces greatly.
Summary of the invention
The utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide long pipe fittings inner surface and removes burr broaching tool, utilizes to drive broaching tool is pulled through long pipe fittings internal diameter, because broaching tool overall dimensions can change.In the course of work, broaching tool need not be dismantled, convenient, efficiency is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: long pipe fittings inner surface is removed burr broaching tool, wherein, comprise broaching tool axle core, be fixed on ringfeder outside broaching tool axle core, be located at the cutter bit of ringfeder outside, the back-up ring spacing to cutter bit, broaching tool integral body is located at inside pipe fitting, and cutter bit is vertical with broaching tool axle core.
The quantity of described cutter bit is established and is had three layers along broaching tool axle core, and every layer comprises 4 blades, the sector structure that is shaped as central angle 90 degree of every blade.In every layer of described cutter bit, between the blade of central angle 90 degree sector structures, be provided with gap.Stagger in three layers of described cutter bit gap between layers.
When cutter bit enters from pipe fitting one end, owing to being subject to the frictional force effect counter motion of pipe internal surface outside cutter bit, cutter bit moves as certain distance along ringfeder, and the integral diameter of cutter bit dwindles, and broaching tool overall dimensions diminishes; When broaching tool pulls back plucking thorn from the other end, owing to being subject to the frictional force effect counter motion of pipe internal surface outside cutter bit, cutter bit moves as certain distance along ringfeder, and the integral diameter of cutter bit increases, and it is large that broaching tool overall dimensions becomes.This process broaching tool need not be dismantled; And three layers of cutter bit draw and be once equivalent to process three times, facilitate efficiency high.
Compared with prior art, beneficial effect is: of the present utility model simple in structure, long pipe fittings inner surface is removed burr broaching tool, utilizes to drive broaching tool is pulled through long pipe fittings internal diameter, because broaching tool overall dimensions can change.In the course of work, broaching tool need not be dismantled, convenient, efficiency is high.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is cutter bit structural representation of the present utility model.
Fig. 3 is ringfeder structural representation of the present utility model.
The specific embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; For better explanation the present embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known configurations and explanation thereof may to omit be understandable.In accompanying drawing, describe position relationship only for exemplary illustration, can not be interpreted as the restriction to this patent.
As Figure 1-3, long pipe fittings inner surface is removed burr broaching tool, wherein, comprise broaching tool axle core, be fixed on ringfeder 2 outside broaching tool axle core, be located at the cutter bit 1 of ringfeder 2 outsides, the back-up ring 3 spacing to cutter bit 1, broaching tool integral body is located at inside pipe fitting, and cutter bit 1 is vertical with broaching tool axle core.The quantity of cutter bit 1 is established and is had three layers along broaching tool axle core, and every layer comprises 4 blades, the sector structure that is shaped as central angle 90 degree of every blade.In every layer of cutter bit 1, between the blade of central angle 90 degree sector structures, be provided with gap.Stagger in three layers of cutter bit 1 gap between layers.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.All any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of the utility model claim.
