Description
Technical field
Pipeline tapping technical field of operation is the utility model is related to, more particularly to a kind of new suction bits boring cutter.
Background technology
In pipeline tapping operation, for pipe with small pipe diameter steel pipeline perforate, existing common boring cutter, by centre drill, cylinder
Knife, U-shaped card composition, by centre drill subdrilling way pipe fitting when which uses, centering is cut through by cylinder hilt pipe fitting again, then by U
Shape card hangs up material block;Producing many iron filings in Tapping procedures can be trapped in pipeline；This kind of boring cutter operating type is deposited
The problem of be：1st, the material bits being detained in pipeline can reduce the sealing performance of closure operation, because during closure operation, fall in steel pipe
Interior iron filings are not removed, and iron filings are also easy to produce between block head and steel pipe inner wall in closure, so as to influence to block operation
Sealing performance；2nd, the conveying equipments such as pipeline valve and filter can be impacted in course of conveying.
The content of the invention
The utility model deficiency for more than, proposes a kind of new suction bits boring cutter, it is therefore intended that, in pipeline tapping operation
In, effectively remove perforate operation and fall the iron filings in steel pipe, ensure leakproofness and pipeline valve and filter of closure operation etc.
Conveying equipment is unaffected in course of conveying.
A kind of new suction bits boring cutter, containing center drill rod, cylinder knife, spring, baffle ring, magnet steel and center bit, the center
Drilling rod is located at the position of center line that novel small diameter inhales bits boring cutter, and the cylinder knife is the tubular knife being placed in center drill rod
Tool, the center bit are installed on the lower end of center drill rod, the baffle ring and magnet steel are sequentially placed above the center bit,
The spring is placed in the top of magnet steel and the inner side of the cylinder knife.
Further, the cylinder knife is a circular knives, and the lower end edge of a knife of cylinder knife is higher than the center bit lower end edge of a knife, effect
It is to allow center bit to be first punched out to pipeline, and fixes the position of overall boring cutter.
Further, the magnet steel is the magnetic magnet steel of annular, and magnet steel string is in the center drill rod, and magnet steel is described in
Center drill rod moves up and down, its effect is the iron filings when adsorbing perforate, and down past along the center drill rod in punch process
Upper movement.
Further, the shape of the baffle ring is circular ring shape, the baffle ring be located at the center bit and the magnet steel it
Between, its effect is to play cushioning effect, is avoided during center bit and magnet steel direct collision, the baffle ring outside diameter be less than or equal to
The outside diameter of heart drill bit, avoids baffle ring when center bit is in punching from being suspended to crumble.
Further, the spring is located in cylinder knife, is placed on the magnet steel, and goes here and there in the center drill rod, its
Effect is under spring force, and magnet steel is always maintained at close to center bit one end, when in center bit toward lower section punch process, again
The magnet steel can be allowed up to move；Its length extends to top on the inside of the cylinder knife, its effect is to greatest extent
Utilize the cylinder knife inner space.
Specifically implementation steps are：Using the utility model proposes new suction consider boring cutter to be worth doing, new suction bits boring cutter is whole
Rotation is punched out body at a high speed, and the center bit first cuts pipe fitting, cuts through centering stabilization after pipeline, then the cylinder
Knife starts gradually that cutting is until cutting through pipeline, during cutting, tiny iron filings that magnet steel absorption is scattered, with opening
Hole is goed deep into, and magnet steel slowly up moves, and adsorbs all metal fillings to drop, after cutting through, then will material crumble block by the magnet steel
Adsorb together, pipeline is taken out of by center drill rod, completes perforate operation.
The main efficacy results of the utility model are：The resistance that the cutter is run into when implementing and cutting is small, when can shorten perforate
Between, meanwhile, the material bits of cutting can be adsorbed, and the material block cut is lifted, improve operating efficiency.
Brief description of the drawings
Fig. 1 is the new suction bits boring cutter structure diagram of the utility model embodiment.
Embodiment
The utility model is described in detail below with reference to specific embodiments and the drawings.
Referring to Fig. 1, new suction bits boring cutter 10 is shown, containing center drill rod 1, cylinder knife 2, spring 3, baffle ring 4,5 and of magnet steel
Center bit 6, for center drill rod 1 positioned at the position of center line for inhaling bits boring cutter 10, cylinder knife 2 is the cylinder being placed in center drill rod 1
Shape cutter, center bit 6 are installed on the lower end of center drill rod 1, and the top of center bit 6 is sequentially placed the baffle ring 4 and magnet steel
5, spring 3 is placed in the top of magnet steel 5 and the inner side of the cylinder knife 2.
Further, cylinder knife 2 is a circular knives, and the lower end edge of a knife of cylinder knife 2 is higher than the 6 lower end edge of a knife of center bit, effect
It is to allow center bit 6 to be first punched out to pipeline, and fixes the position of overall boring cutter.
Further, magnet steel 5 is the magnetic magnet steel of annular, and magnet steel 5 is gone here and there in center drill rod 1, and magnet steel 5 is along center drill rod
1 moves up and down, its effect is iron filings when using magnetic absorption perforate, and past along center drill rod 1 in down punch process
Upper movement.
Further, the shape of baffle ring 4 is circular ring shape, and between center bit 6 and magnet steel 5, its effect has been baffle ring 4
To cushioning effect, center bit 6 and 5 direct collision of magnet steel are avoided.
Further, spring 3 is located in cylinder knife 2, is placed on magnet steel 5, and goes here and there in the center drill rod 1, it is acted on
Under spring force, magnet steel 5 is always maintained at close to 6 one end of center bit, when in center bit 6 toward lower section punch process, again
Magnet steel 5 can be allowed up to move；3 length of spring extends to 2 inner side top of a knife, its effect is to maximally utilise the cylinder
2 inner space of knife.
Specifically implementation steps are：Using the utility model proposes new suction consider boring cutter 10 to be worth doing, boring cutter is considered in new suction to be worth doing
10 overall rotations at a high speed are punched out, and center bit 5 first cuts pipe fitting, cut through centering stabilization after pipeline, then cylinder knife 2
Start gradually to cut until cutting through pipeline, during cutting, magnet steel 5 adsorbs the tiny iron filings being scattered, perforate at any time
Deeply, magnet steel 5 up moves at leisure, does not influence the punching of center brick 6, after cutting through, then by magnet steel 5 will expect crumble block together
Absorption, takes pipeline out of by center drill rod 1, completes perforate operation.
The main efficacy results of the utility model are：The resistance that new suction bits boring cutter 10 is run into when implementing and cutting is small, energy
Shorten the perforate time, meanwhile, the material bits of cutting are adsorbed, and the material block cut is lifted, operating efficiency is improved, new suction bits are opened
Hole knife 10 is adapted to carry out perforate for minor diameter steel pipe.
Above disclosed is only a kind of the utility model preferred embodiment, cannot limit this practicality with this certainly
New interest field, therefore the equivalent variations made according to the utility model claims, still belong to what the utility model was covered
Scope.
