Description
Technical field
The invention belongs to pressure vessel manufacturing technical fields, in particular to close to more piece tower type container end flange with boring machine
The method of cover processing.
Background technique
Flange is the important component of more piece tower type container, to the rough surface of more piece tower type container end flange end sealing surface
Spend it is more demanding, be Ra0.8~1.6, in the prior art, single flange sealing surface may be implemented in general-purpose grinder and center lathe
Precision Machining, but after flange and shell ring are welded into tower section, the length of each tower section is longer, generally 4~6 meters, and flange
Be relatively large in diameter, generally higher than 1 meter, general-purpose grinder and center lathe can not clamping, if more piece tower type container end flange list
Part is individually integral using welding again with shell ring after existing center lathe and general-purpose grinder processing, then not can guarantee tower body group postwelding
The requirement of final entirety verticality, and boring machine itself is also without tower two end flanges of equipment of Precision Machining large scale in the prior art
The ability of sealing surface.
Application No. is a kind of flange sealing trough grinding device of the disclosure of the invention of CN201610587602.0 and its users
Method, structure have positioning screw, jackscrew, bracket, grinding ring handle etc.；The shape and pressure vessel Work piece sealing to be added of grinding ring
The shape of slot is adapted, and selects the grinding ring of corresponding specification, device is fixed on workpiece to be added, and adjusting positioning screw makes to grind
Ring touches the seal groove of workpiece to be added, installs abrasive pastes additional；The handle that can be manually rotated on grinding ring is ground.The invention is method
The grinding of blue seal groove and to can be manually rotated grinding, large labor intensity, low efficiency can only also realize single flange components seal groove
Processing.
Summary of the invention
Problem to be solved by this invention is to overcome the deficiencies of the prior art and provide to guarantee that tower body group postwelding is final
The method that more piece tower type container end flange sealing surface is processed with boring machine that whole verticality requires.
What the present invention took includes as follows with technical solution of the boring machine to the method that more piece tower type container end flange is processed
Step:
Step 1, the clamping and centering of tower section:
Fixing seat and bracket are installed on the workbench of numerical control borer, the upper surface of the fixing seat at both ends is connected on V-arrangement
Tower section is placed on intermediate bracket by fixture block and V-arrangement lower fixture block, while passing through the V-arrangement upper fixture block at both ends and V-arrangement lower fixture block folder
Firmly tower section and centering, keep the axis of tower section parallel with the upper surface of numerical control borer workbench, and the flange sealing surface at tower section both ends
It is vertical with the upper surface of numerical control borer workbench, wherein one end of tower section is right flange sealing surface, and the other end is left flange seal
Face, the right flange sealing surface are parallel to each other with left flange sealing surface, and the adjustment right both ends of good position rear left are locked with long threaded rod respectively
It fastens；
Step 2, the right flange sealing surface of roughing:
After the completion of the clamping of tower section and centering, boring cutter is installed on the chuck of numerical control borer spindle box；With boring cutter roughing tower
Save the right flange sealing surface of end flange sealing surface；
Step 3 replaces skive:
Roughing finishes, and after the requirement through examining surface roughness to meet finishing, boring cutter is removed, in numerical control borer spindle box
Skive is replaced on chuck；
Step 4 finishes right flange sealing surface:
On the basis of roughing right flange sealing surface, right flange sealing surface is finished using skive, keeps right flange close
The surface roughness of cover reaches Ra0.8~1.6；
Step 5, the left flange sealing surface of roughing:
Specific method is identical as step 1 and step 2；
Step 6 finishes left flange sealing surface:
Specific method is identical as step 3 and step 4.
Step 3: skive described in step 4 and step 6 includes skive connecting rod, in boart boart
The left side center of wheel connecting rod is threaded hole, is fixedly connected with bowl-type by soket head cap screw and briquetting in the threaded hole
Metallic matrix is equipped with annular diamond grinding head in the end of bowl-type metallic matrix.
The diameter of the skive connecting rod is identical as the diameter of boring cutter handle.
The surface roughness of right flange sealing surface and left flange sealing surface described in step 4 and step 6 is Ra 0.4.
Compared with prior art, the beneficial effects of the present invention are:
(1) present invention solves in the prior art that more piece tower type container diameter is big, and length is long, the flange at more piece tower type container both ends
Sealing surface is wanted to reach the higher depth of parallelism and high surface roughness, and center lathe and grinding machine, which cannot achieve, to be loaded, commonly
Boring machine can be realized clamping, but the problem of be unable to reach the surface roughness of requirement, realize on numerical control borer to more piece tower
The roughing and finishing of the tower section both ends flange sealing surface of formula container, surface roughness have reached the requirement of Ra0.8~1.6,
Actual measurement can reach the processing request of the higher surface roughness of Ra0.4, and with same boring machine, clamped one time centering can be real simultaneously
Current boring cutter roughing and with skive finish two kinds of processing methods, and equipment do not have to displacement, it is only necessary to pass through replacement
Boring cutter and skive can realize the processing of two steps in a station, ensure that machining benchmark is constant, not will cause secondary dress
Press from both sides bring accumulated error；
(2) present invention, which only needs clamping twice, can be completed the finishing of two end faces of tower section, ensure that tower section both ends flange seal
The verticality in face and tower body axis, so ensure that more piece tower section composition tower body assembling after tower body entirety straightness and sealing
It is required that；
(3) present invention installation is simple, and easy to operate, labor intensity is low, saves time cost, improves production efficiency, can be extensive
Finishing for middle pressure, high pressure, the various pressure vessel group postwelding tower section flange sealing surfaces of super-pressure.
