Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figure 1, Figure 2, Figure 4 shows, this perforating cutter for being used for electric smelting saddle type bypass includes blade 1 and blade 2, blade 1
In a tubular form and the internal inner chamber 11 with column, the outer peripheral face of blade 1 have the thread segment 12 for being used for coordinating with electric smelting saddle type, knife
Sword 2 is located at the bottom of blade 1, and blade 2 is serrated and is evenly arranged successively in a ring around the axis of blade 1, the top of blade 2
Face tilts towards inner chamber 11 from the outside to the core.The perforating cutter of electric smelting saddle type bypass is used to carry out perforate to pipeline with pressure, is being opened
During hole operation, electric smelting saddle type is first closely connected with being bonded after the pipeline of perforate after electric smelting, then using corresponding tool drives electricity
Perforating cutter in molten saddle bypass rotates, because perforating cutter outer peripheral face has the thread segment 12 coordinated with electric smelting saddle type,
Blade 1 is pressed in assigned direction rotation process, and perforating cutter can be bypassed to lower feeding along electric smelting saddle type, and passes through the rotation of blade 2
Turn to carry out cutting perforate to lower side conduit, finally drive perforating cutter reversion to exit simultaneously return from pipeline again, make to flow in pipeline
Body medium is bypassed by electric smelting saddle type and conveyed, and completes tap operation.By setting blade 2 uniform successively around the axis of blade 1
Arrangement, make cutting of the perforating cutter for pipeline also more uniform smooth, make Tapping procedures more steady, by setting blade 2
Top surface tilted from the outside to the core towards inner chamber 11, make blade 2 that there is inside gradient, blade 2 and pipeline so in Tapping procedures
Contact area diminishes, and perforate torsion is also smaller, while reduces the generation of frictional heat in Tapping procedures, so as to ensure and perforate
The electric smelting saddle type internal thread that cutter coordinates is not easy temperature distortion, improves the stability of perforate operation.
As shown in Fig. 2 the bottom of blade 2 and the junction of blade 1 are in the conical surface or round-corner transition.By the bottom for setting blade 2
Portion and the junction of blade 1 are the conical surface or round-corner transition, add the intensity of blade 2, blade 2 is not easy stress in Tapping procedures
Deformed in phase, so as to improve the stability of perforate operation.
As in Figure 2-4, the diameter of the inner edge of blade 2 is less than the diameter of inner chamber 11.By setting the inner edge diameter of blade 2 small
Diameter in inner chamber 11, the mouth of so formation cutter is small interior big, and caused scrap and column waste material will be limited in Tapping procedures
In inner chamber 11, pipeline is will not fall into, so as to improve the cleannes of perforate operation and ensure the safe operation of pipe network.Further
For, blade 2 has four, and jagged 21 are opened up on the inside of every joint of two blade 2, and the outline of breach 21 is in batter post shape, lacks
The axis of mouth 21 extends towards the top of blade 1.By opening up the breach 21 of batter post shape on the inside of each joint of blade 2, enter one
The contact area of blade 2 and pipeline when step reduces perforate, so that scrap in banding and reduces perforate torsion during 2 perforate of blade
Power, cleannes and stability are more preferable, and batter post has guide effect in face of caused scrap, by the axis court for setting breach 21
The top extension of blade 1, can be such that caused scrap slips into inner chamber 11, improve the cleannes of perforate operation.Preferably,
The outer peripheral face of blade 2 is identical with the outer peripheral face diameter of blade 1.By setting the outer peripheral face of blade 2 and the outer peripheral face diameter of blade 1
It is identical, blade 2 and the outer peripheral face of blade 1 is uniformly processed, so as to improve the intensity of cutter and save production cost.
As Figure 1 and Figure 4, the top center of blade 1 offers hexagon ring 13, and the outer rim of hexagon ring 13 is through chamfered.
Hexagon ring 13 is opened up by the top center in blade 1, enables spanner or motor to drive perforating cutter to turn by hexagon ring 13
It is dynamic, chamfering is set by the outer rim in hexagon ring 13, guiding can be provided for the assembling of the driving instruments such as spanner, so as to improve out
The convenience of hole operation.
As shown in Figure 3, Figure 4, the bottom center of inner chamber 11 offers the screwed hole 14 for assembling positioning drill bit, screwed hole
14 can be connected with inner chamber 11.Screwed hole 14 is opened up by the bottom center in inner chamber 11, can perforating cutter to wall thickness compared with
Such as spitting drill first-class accessory is installed when big pipeline carries out tap operation additional in screwed hole 14 as needed, so as to improve boring cutter
The work scope of application of tool.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
