Description
Technical Field
The utility model relates to a protective cap of cutting device cutter inside the pipe utensil, especially a cutting device is from chip removal protective cap in pipe utensil.
Background
Oil gas well among the oil industry, along with the extension of live time, casing pipe and oil pipe often can the undergauge in well completion tubular column and the production string, the crooked condition of oil casing pipe rupture even takes place, if meet the above-mentioned damage of oil casing pipe and influence the condition of production, just need to propose damaged oil pipe tubular column and casing pipe tubular column, change oil pipe or the casing pipe of damage. When the tubular column is taken out of the ground, if the damaged oil pipe or sleeve pipe is stuck with the undamaged oil pipe or sleeve pipe and cannot be separated, the cutting is a method for quickly separating the stuck oil pipe or sleeve pipe from the undamaged oil pipe or sleeve pipe, so that the construction time can be saved, and the construction cost can be saved.
The internal electronic cutting means of current oil casing, because cutting blade's helmet is unanimous with the instrument external diameter, the shape is different and do not have the chip removal function, when instrument diameter is close with by cutting pipe utensil internal diameter size, can only cut in vertical direction, if carry out horizontal cutting under this kind of condition, a large amount of cuttings that produce in the cutting process, fill up the gap between cutting means and the oil casing tubular product very easily, crowd dead cutting means's motion, cause the cutting construction failure.
The internal cutting device for cutting the pipe is a device for cutting off the pipe from the inside of an oil pipe, a casing pipe or other pipes by supplying power to the oil pipe, the casing pipe or other pipes through a cable, and a protective cap arranged at the end part of an internal cutting tool is only a conical cap, so that the cutting tool is prevented from being damaged in the cutting process, and the use effect is not ideal.
The guard of the inner cutting blade of the cutting device in the pipe should be improved.
Disclosure of Invention
The utility model provides a cutting device protects cap from chip removal in pipe utensil avoids in the pipe utensil the piece that cutting device's interior cutting blade cut down to pile up including cutting blade and by the gap between the cutting pipe utensil body, improves cutting device's work efficiency in the pipe utensil, enlarges cutting device's application range in the pipe utensil.
The technical solution of the utility model is that:
the utility model provides a cutting device is from chip removal helmet in pipe utensil includes the helmet body, and helmet body upper portion is the toper top, is equipped with interior cutting blade flexible groove, screw fixed orifices and chip groove in the helmet body, and the screw fixed orifices is established in the below of interior cutting blade flexible groove, and the chip groove is established at the middle part of helmet body.
The chip groove is a spiral groove which is spirally arranged in the middle of the helmet body, and the depth of the groove body of the chip groove is set between one fourth and one third of the thickness of the helmet body.
One end of the chip discharge groove starts to spiral from one side of the inner cutting blade telescopic groove and is arranged in the middle of the helmet body above the inner cutting blade telescopic groove.
And the spiral rotating direction of the chip discharge groove is consistent with the rotating direction of the cutting device in the pipe.
The shape and the number of the inner cutting blade telescopic grooves are the same as those of the inner cutting blades in the cutting device in the pipe.
The lower end of the protective cap body between the screw fixing holes is provided with a dismounting groove.
The utility model discloses a show the result of use and be: the utility model discloses a helmet of cutting device in pipe utensil, the chip groove has been processed on the helmet body. The protective cap is mounted on the front end of the inner cutting blade of the cutting device in the pipe tool and can rotate along with the rotation of the cutting device in the pipe tool. When the inner cutting blade extends out of the protective cap and cuts debris from the oil casing or other pipe, the debris on the outside of the protective cap enters the junk slots as the protective cap rotates. Because the chip groove is a spiral groove which starts to spiral from one side of the telescopic groove of the cutting blade, the spiral rotating direction of the chip groove is consistent with the rotating direction of the cutting device in the pipe, and chips can enter the chip groove along with the rotation of the protective cap body and move forward along the conical top of the chip groove and are accumulated in a non-working area outside the conical top of the protective cap. Therefore, the cutting device in the pipe does not generate accumulation and extrusion of cutting chips under various working conditions, and the cutting chips are discharged to a non-working area by the spiral chip grooves immediately after being generated, so that the working area is not influenced. Effectively improves the cutting efficiency and avoids the accident that the inner cutting blade is blocked by the scraps.
For the electric cutting tool in the existing oil casing, after the protective cap is used, the protective cap can be driven to rotate by the cutting rotation action of the electric cutting tool in the oil casing, and chips in the cutting process enter a chip groove of the protective cap and can be discharged to a non-working area from the spiral chip groove. Can enlarge current electric cutting tool's application range, not only can normally work under cutting blade and the condition that the oil casing is vertical direction, also can normally work under the condition that cutting blade and oil casing are the horizontal direction moreover.
To sum up, the utility model discloses the result of use that is showing has.
