Abstract

The utility model discloses a kind of large diameter pipe aperture knife tools, and including handle of a knife, described handle of a knife one end is connected with knife bar, the end set of the knife bar has cutterhead, several radial grooves are provided on the cutterhead end face, blade in the radial groove is housed, gland is provided with above the blade.The beneficial effects of the utility model：It solves radial drilling machine merely using the natural mode of conventional cutlery, boring cutter class cutter is applied in the machining of drilling machine, cutter has added gland, has the function of to compress positioning, solves the disadvantage that not feeling relieved using conventional boring cutter during radial drilling machine processing；It solves the problems, such as to process on boring machine, it can be with a variety of lathes（Boring machine, drilling machine）Processing, alleviates production pressure, shortens the production cycle, reduce processing cost；Blade is conventional lathe tool knife side used by this cutter, more much lower than NC cutting tool and major diameter drill bit reamer price, also greatly reduces processing cost in this way.

Description

Large diameter pipe aperture knife tool

Technical field

The utility model is related to mechanical production devices, relate in particular to a kind of large diameter pipe aperture knife tool.

Background technology

The usually relatively more pore size of heat exchanger tube sheet is 50 ㎜ of Ф hereinafter, the tube sheet pore of these specifications is mostly in rocking arm Using the processing technology bored, cut with scissors on drilling machine.As pore diameter >=50 ㎜ of Ф, since bit diameter is larger, drill bit reconditioning relies on Manually, if head point slightly deviation, the pore drilled out will not just, and precision size is extremely difficult to drawing requirement.So work as pore Majority is all processed in numerical control boring during diameter >=50 ㎜ of Ф, and the corresponding tube sheet diameter of pore of major diameter all can be very big, Have very high requirement for the working ability of boring machine in this way, and so larger equipment lathe of working ability, all it is diluter Few, multiple workpiece are processed in this equipment may require that for a long time, and it is that can not meet to produce mating want to depend merely on a machine tool It asks.

Utility model content

For the problems in the relevant technologies, the utility model proposes a kind of large diameter pipe aperture knife tools, can effectively solve The certainly above problem.

To realize the above-mentioned technical purpose, the technical solution of the utility model is realized in：

A kind of large diameter pipe aperture knife tool, including handle of a knife, described handle of a knife one end is connected with knife bar, the end of the knife bar Cutterhead is provided with, is provided with several radial grooves on the cutterhead end face, equipped with blade in the radial groove, on the blade Side is provided with gland.

Further, the axis of the handle of a knife, knife bar, cutterhead and gland is in the same horizontal line.

Further, the quantity of the radial groove is three, and three radial grooves are distributed on cutterhead end face.

Further, the shape of the handle of a knife is round platform.

The beneficial effects of the utility model：Solves radial drilling machine merely using the natural mode of conventional cutlery, by boring cutter Class cutter is applied in the machining of drilling machine, and cutter has added gland, has the function of to compress positioning, is solved radial drilling machine and is added The shortcomings that working hour can not be felt relieved using conventional boring cutter；It solves the problems, such as to process on boring machine, it can be with a variety of lathes（Boring Bed, drilling machine）Processing, alleviates production pressure, shortens the production cycle, reduce processing cost；Blade used by this cutter It is more much lower than NC cutting tool and major diameter drill bit reamer price for conventional lathe tool knife side, it also greatly reduces add in this way Work cost.
