Abstract
The utility model provides an on-line closing device for a pipe end, which comprises a support disk, three conical rolls mounted on the support disk and a mandrel mounted in the center of the support disk, wherein the three conical rolls are fixed on the support disk at equal intervals by roll shafts. The on-line closing device has the effects that the on-line closing device is simple in structure, and low in manufacturing cost and maintenance cost, and has few faults. The on-line closing device is applicable to the processing of TPCO series special buckles for petroleum sleeves and oil pipes, requirements of the TPCO series buckles are met, and a processing technology of on-line closing for the pipe end is achieved. The on-line closing device is a special tool and applicable to multiple on-line closing occasions, and the influence of off-line closing on production is reduced.
Description
Technical field
The utility model relates to a kind of closing device, and the online closing device of a kind of pipe end particularly is applicable to the process of the TPCO series special buckle processing of petroleum casing pipe and oil pipe.
Background technology
The TPCO series special buckle product of petroleum casing pipe and oil pipe, to the pipe end of steel pipe by comparatively special specification 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, the contracting equipment normal operation cold-heading formula closing in of off-line or roof pressing type contracting equipment close up to the pipe end of steel pipe, this off-line closes up and certainly leads to expense, also can produce simultaneously the waste product of some steel pipes because of the off-line transportation, so cause very large waste.
Summary of the invention
For solving the technical problem of above-mentioned existence, the purpose of this utility model provides the online closing device of a kind of pipe end, has solved online closing in problem, has also reduced the cost of product simultaneously.
For achieving the above object, the technical solution adopted in the utility model 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 on the supporting disk and the footstalk that installs at the supporting disk center; Described three tapered rollers uniformly-spaced are fixed on the supporting disk by roll shaft.
Effect of the present utility model 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 the processing of petroleum casing pipe and oil pipe TPCO series special buckle, guarantees the requirement of TPCO series button-type, has realized the online processing technology that closes up of screw thread pipe end.This online closing device is a kind of specific purpose tool, is applicable to the online multiple occasion that closes up, and has reduced because of the impact of off-line closing on producing.

The specific embodiment
By reference to the accompanying drawings the online closing device structure of pipe end of the present utility model is illustrated.
As shown in Figure 1, 2, the online closing device of pipe end of the present utility model, this closing device include supporting disk 2 and are installed on three tapered rollers 3 on the supporting disk 2 and the footstalk 4 that installs at supporting disk 2 centers; Described three tapered rollers 3 uniformly-spaced are fixed on the supporting disk 2 by roll shaft 5.Described three tapered roller 3 structures and tapered roller tapering thereof are 16 °.
One end of described roll shaft 5 is internal thread, and the other end of roll shaft 5 is 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.
Shown in Fig. 3,4, in concrete process implementing, can be installed on the footstalk 4 of the online closing device of screw thread pipe end of the present utility model on the tool rest 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 closes up, is distributed on the supporting disk 2, closing device is along the feeding of steel pipe axis, and steel tube end part forms frustum type and closes up under the roll extrusion of three tapered rollers 3.
The online closing device function of pipe end of the present utility model is achieved in that
Take φ 73 steel pipe TPCQ (EX) Premium connections the blank tubing pipe end is closed up as example:
Pipe external diameter 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/ turns
This specification steel pipe closes up: L=9-11mm, α≤8 °
The online closing device of pipe end of the present utility model 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 enter closing device, rotation after tapered roller 3 contacts with steel pipe 9, machine tool feed reaches feed-disabling after the requirement length, the pipe end of steel pipe 9 closes up and finishes, and can carry out other part operations of next step processing.
The online closing device of pipe end of the present utility model is on probation at the machine for threading tube body of special, the special button of Tianjin Steel Pipe Corp.'s pipe processing department 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 pipe end closes up needs off-line processing.
The actual operating position of the online closing device of pipe end of the present utility model is as follows:
The online closing device of this pipe end is installed on the cutter tower of machine for threading tube body, and this device carries out closing in work online, and the indices of closing in meets the requirement of special buckle processing, has improved simultaneously the efficient of processing, has reduced percent defective.
It is about 15% that the use of the online closing device of pipe end of the present utility model has improved operating efficiency, because of the link of having bad luck in the middle of having reduced, and the product cost that improved quality of products.
