Blue sealing surface water wave line processing method.
Background technique
Centrifugal compressor is play an important role in the national economic development, has especially played weight in natural gas transportation field
It acts on.According to design requirement, pipeline compressor air duct belongs to prominent face (RF) flange, for the leakproofness for guaranteeing flange, is setting
Meter drawing in for flange sealing surface design have water wave line for reinforce sealing.Due to processing technology requirement, the wind of compressor
Drum flange, which finally finishes, must be welded to rear progress on casing, including Flange Plane, seam allowance, sealing surface etc..Thus can not
The finishing of flange is efficiently completed using lathe, it can only be processed using numerical control borer or milling equipment.
In the connection of process equipment, pipeline and valve, flanged joint is the principal mode of static seal, and application is very wide
It is general.The leakage occurred on flange and gasket interface is known as boundary leakage, and boundary leakage is the main path that leakage generates.Sealing
The sealing between flange is mainly reinforced in the effect of face water wave line, and the pressing force that bolt generates passes through flange sealing surface (seal face)
Gasket is passed to, so that gasket is generated enough elastic-plastic deformations, thus by the non-gold in gap rough between flange screw face
Category gasket compression is filled into sealing waterline and fills up compacting, so that not having leakage path at contact surface, achievees the purpose that sealing.
Referring to Fig. 1 and Fig. 2, traditional water wave line processing method rose cutter bigger using φ 3 or diameter passes through numerical control dragon
Door milling machine or numerical control borer X-axis and Y-axis interlock method, which are realized, to be processed.Since casing water wave line machining accuracy is higher, needed before processing
Air duct flange sealing surface is levelling, it can be processed after levelling, processing feeding mode is optimal to use helical wire form, from flange
The feed of sealing surface side goes out knife from the other side.The method processing water wave line works well, but processing efficiency is lower, process time
It is determined by machine spindle speed and the amount of feeding, the numerical control device time is longer in occupancy factory, seriously affects production efficiency.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of pipeline high in machining efficiency is close with compressor air duct flange
Cover water wave line processing method.
In order to solve the above technical problems, the present invention provides a kind of pipeline compressor air duct flange sealing surface water wave lines to add
Work method, includes the following steps:
The good air duct of semifinishing and casing are welded:

Folder；
Table centering is beaten to the end face of air duct flange and outer circle using facing head, centering precision need to be not less than 0.05mm, centering
Clamping platen afterwards；
The mechanical clamped cutting tool that blade is carbide chip is mounted on facing head, the input processing journey in numerical control borer
Sequence, to knife from air duct flange sealing surface diameter minimum；
Starting numerical control borer, main shaft drives facing head rotation, while knife handle being driven to move on facing head along U axis direction,
To realize that cutter is mobile, cutter is moved to air duct flange sealing surface diameter maximum and completes processing.
Further, the amount of feeding set in the processing program is equal to revolution multiplied by water wave string pitch.
Further, the water wave string pitch requires 0.45-0.55mm.
Further, the water wave line helically form.
Further, the mechanical clamped cutting tool includes the knife bar being mounted on knife handle, and the blade being fixed on knife bar, described
Knife handle is mounted on facing head, and the knife bar is formed using 45# steel forgings deformation, and the blade uses carbide chip.
Further, the radius of corner of the blade is set as 1.5-3mm, radius of corner 2mm.
A kind of pipeline provided by the invention compressor air duct flange sealing surface water wave line processing method, utilizes numerical control borer
Facing head to air duct flange sealing surface carry out the processing of water wave line, and use blade for carbide chip mechanical clamped cutting tool progress
Processing is rotated by main shaft and facing head is driven to rotate in U axis direction, and facing head rotation band cutter is mobile, and cutter is from air duct method
Blue sealing surface diameter smaller part starts, and constantly moves in U axis direction, until it is maximum to be moved to air duct flange sealing surface diameter
Place completes the processing of spiral shape water wave line on air duct flange sealing surface, not only easy to process, but also processing efficiency and processing matter
It measures relatively high.
