The online opening closing device for the pipe end has the effects of simple structure, low manufacturing cost, fewer faults and small maintenance cost. The online opening closing device is suitable for machining petroleum sleeves and oil pipe TPCO series special buckles and guarantees the requirements of the shapes the TPCO series special buckles, so that the machining process of the online opening closing of the pipe end is realized. The online opening closing device is a special tool and is applicable to various fields of online opening closing, so that the influences of offline opening closing on the production are reduced.
Description
Technical field
The present invention relates to a kind of closing device, the online closing device of particularly a kind of pipe end is applicable to the special process of buckleing processing of TPCO series of petroleum casing pipe and oil pipe.
Background technology
The special buckle product of TPCO series of petroleum casing pipe and oil pipe; To the pipe end of steel pipe by comparatively special technique requirement; Be that pipe end will have tapering to be not more than 16 °, length to be not more than the inside taper of 25mm and to close up; Closing in operation in the past all is that off-line closes up, and the closing in equipment of off-line generally uses the cold-heading formula to close up or roof pressing type closing in equipment closes up to the pipe end of steel pipe, and this off-line closes up and certainly leads to expense; Also can produce the waste product of some steel pipes simultaneously because of the off-line transportation, so cause very big waste.
Summary of the invention
For solving the technical problem of above-mentioned existence, the purpose of this invention is to provide the online closing device of a kind of pipe end, solved online closing in problem, also reduced the cost of product simultaneously.
Be to realize above-mentioned purpose, the technical scheme that the present invention adopts provides the online closing device of a kind of pipe end, and wherein: this closing device includes supporting disk and is installed on three tapered rollers and the footstalk of supporting disk center installation on the supporting disk; Said three tapered rollers uniformly-spaced are fixed on the supporting disk through roll shaft.
Effect of the present invention is used this online closing device, because simple in structure, low cost of manufacture, simultaneous faults is few, and maintenance cost is few.This online closing device is applicable to petroleum casing pipe and the special processing of buckleing of oil pipe TPCO series, guarantees the requirement of TPCO series button-type, has realized the processing technology of the online closing in of screw thread pipe end.This online closing device is a kind of specific purpose tool, is applicable to the multiple occasion of online closing in, has reduced because of the influence of off-line closing in to producing.

Fig. 4 is that sketch map is implemented in online closing device closing in of the present invention.
Among the figure:
1, bolt 2, supporting disk 3, tapered roller 4, footstalk 5, roll shaft
6, nut 7, pad 8, cutter are sat 9 steel pipes
The specific embodiment
In conjunction with accompanying drawing the online closing device structure of pipe end of the present invention is explained.
Like Fig. 1, shown in 2, the online closing device of pipe end of the present invention, this closing device include supporting disk 2 and are installed on the footstalk 4 that install at three tapered rollers 3 and supporting disk 2 centers on the supporting disk 2; Said three tapered rollers 3 uniformly-spaced are fixed on the supporting disk 2 through roll shaft 5.Said three tapered roller 3 structures and tapered roller tapering thereof are 16 °.
One end of said roll shaft 5 is an internal thread, and the other end of roll shaft 5 is an external screw thread, and roll shaft 5 passes supporting disk 2 and tapered roller 3, and an end of roll shaft 5 passes pad 7 with bolt 1 and is connected with tapered roller 3, and the other end of roll shaft 5 is anchored on nut 6 on the through hole of supporting disk 2.
Like Fig. 3, shown in 4, in concrete process implementing, can be installed on the footstalk 4 of the online closing device of screw thread pipe end of the present invention on the cutter seat 8 of lathe, to realize the technical process of on-line machining.The tapering of three tapered rollers 3 is made as 16 °, and according to the diameter of the steel pipe that is closed up, is distributed on the supporting disk 2, closing device is along the feeding of steel pipe axis, and steel tube end part forms the frustum formula and closes up under the roll extrusion of three tapered rollers 3.
The online closing device function of pipe end of the present invention is achieved in that
With the special snapping head of φ 73 steel pipe TPCQ (EX) the blank tubing pipe end being closed up is example:
External diameter of pipe φ 73mm, wall thickness 5.5mm, hardness HRC50
The closing in formula is Lmax=φ D * 5% ÷ 2tg α (wherein 9≤L≤25, α≤8 °)
Machine spindle speed: 100 rev/mins, the amount of feeding: 0.02mm/ commentaries on classics
This specification steel pipe closes up: L=9-11mm, α≤8 °
The online closing device of pipe end of the present invention is installed on the threading tube body machine knife tower; In the car silk first being processed operation that closes up; Steel pipe 9 pipe ends get into closing device, and tapered roller 3 contact with steel pipe 9 afterwards and rotates, and machine tool feed reaches feed-disabling after the requirement length; The pipe end of steel pipe 9 closes up and accomplishes other part operations that can carry out next step processing.
The online closing device of pipe end of the present invention is on probation on the machine for threading tube body of special, the special button of Tianjin Steel Pipe Corp.'s pipe processing portion oil, pipe nipple production line, and result of use is good.Be machined as example with the special production line threading tube body of oil, former this equipment does not have closing device, and the pipe end closing in needs off-line processing.
The actual operating position of the online closing device of pipe end of the present invention is following:
The online closing device of this pipe end is installed on the cutter tower of machine for threading tube body, and this device is online to carry out closing in work, and each item index of closing in meets the requirement of special button processing, has improved the efficient of processing simultaneously, has reduced percent defective.
It is about 15% that the use of the online closing device of pipe end of the present invention has improved operating efficiency, and the link of having bad luck because of in the middle of having reduced has improved product quality and reduced product cost.
