Background technology
Press and open holes are a kind of safe and environment-friendly, economic, efficient working pipeline maintenance techniques, suitable for crude oil, finished product
The normal maintenance transformation and the repairing of burst accident of a variety of medium pipelines such as oil, chemical medium, natural gas（Such as repairing with pressure, more
Change the operations such as corrosion pipeline section, attachment means, point defeated transformation）.Hot tapping machine when being press and open holes operation plugging holes used set
A standby part, the rotation of its critical component axial length 5600mm, outside diameter 186mm, interior circular diameter 148mm, need to exist during manufacture
Two wide 14mm are processed in inner circle, the logical keyway that deep 7mm is parallel to each other, because the domestic temporarily special kerve without shaping is set at present
Standby, the processing method now used has following several：1）Change the existing driven Design of on-line branching machine；Its shortcoming is to make driver
Structure becomes cumbersome, and not only transmission stability is deteriorated, and profile is also more heavy.2）Existing groove broacher is reequiped, manufacture lengthens
Broaching tool；Its shortcoming is due to that equipment cost itself is higher, and repacking investment cost is big, uneconomical, while lengthens broaching tool and make requirement
Higher, using tool steel as raw material, after the processes such as roughing, quenching, finishing, yield rate is less than 50%；3）By pipeline therefrom
The heart is divided into two, and loads by inner circle design requirement in outer pipe, if cylindrical tube wall bores dry hole, endoporus is fixed with mold, cylindrical
Pipe tap carries out submerged-arc welding, then cylindrical to be finished again by design requirement；Its shortcoming one is that stability is poor, and being extremely difficult to design will
Ask, second, the requirement of mutual cooperation part is high, difficulty of processing is big, third, by welding, the mechanical performance of steel is greatly reduced, fourth,
Labor intensive, manufacturing cost are high.
The content of the invention
