At present, along with the development of oil exploration industry, used sucker rod also improves thereupon and upgrades, thereby has improved the capacity of competition of sucker rod product.The sucker rod in the oil extraction and the connected mode of centralizer generally adopt closely cooperating of light round bar and closed loop centralizer.And in well on the sucker rod of nearly km, the 400mm-600mm of being separated by periodically installs the various centralizer of quantity, guarantees that the sucker rod round bar is fixed on oil well central authorities, and round bar does not directly contact with the oil well wall like this, reduces wear raising oil well application life.When sucker rod is done the oil pumping motion under the HTHP in well, material is that light round bar and the material of 30CrMoA is that both thermal expansion degree of nylon 66 centralizers are different, centralizer easily expands than light round bar, make centralizer and light round bar tow out, slide into the shaft bottom under a plurality of centralizers on the round bar, make centralizer ineffective.Sucker rod is connected with centralizer and is damaged, and influenced the application life of sucker rod, oil well.For this reason, the solution sucker rod is that important topic to be solved is arranged with effective combination of centralizer.
Summary of the invention
Purpose of the present invention is exactly for solving in the prior art caducous problem between the light round bar and centralizer, satisfy the demand of sucker rod industry, proposing a kind of novel band and surely follow closely hot rolled circular steel and production method thereof.
The present invention relates to the steady nail of a kind of band hot rolled circular steel, it is characterized in that: have proportional spacing in the both sides of vertical bar round steel, periodically arrange the steady nail that goes on foot, present alternately arranged between the steady nail in both sides.
The shape of steady nail can be cuboid, trapezoidal cone, and the spacing of steady nail is 400-600mm.
A kind ofly produce the production method that band as claimed in claim 1 is surely followed closely hot rolled circular steel, roll forming on full continuously hot rolling bar and shape mill, it is characterized in that: milling train does not change under the prerequisite of material type before finished product, on the roll groove of finished product hot rolling mill, make the groove of specific dimensions, and by the fixing relative position of top and bottom rolls groove, with steel rolling become to have spacing equate, periodically, the round steel surely followed closely of the both sides band of alternately arranging.
Roll out the round steel of the steady nail of band, must use the roll groove of special band groove.Be by beating on roll groove by the electrode prefix that design size is made, and form groove, and forming the promptly steady nail of projection at groove after the steel rolling.Electrode prefix size decision groove size, groove size determines steady nail dimension again.Steady nail dimension size is wanted suitably, and especially steady staple height should guarantee to tangle centralizer, guarantees that again the intensity of steady nail place round steel reaches standard-required.Can not guarantee rolling fault again.
Both sides at round steel all have steady nail, and distance evenly between the steady nail.Processing and installation specification:
1, determines prefix position in roll.Two roll homalocephalus plane parallel are in ground up and down, and the electrode prefix is beaten on the groove of this roll perpendicular to the ground direction;
2, determine the relative distance of the steady nail of top and bottom rolls.Two roll people tooth case homalocephalus plane parallel are in ground, again with its kneading up and down.Error does not differ from two teeth;
3, each component-assembled main points: an end that connects axle docks with people's tooth case, and the other end that connects axle is connected with roll, and top and bottom rolls is surely followed closely unified upwards placement, and the homalocephalus plane parallel is in ground, and top and bottom rolls homalocephalus place difference angle is not more than 15 degree.
Steel rolling delivery channel diameter is suitable, should play the effect of leading steel, prevents the rolling fault of scraping steel again.
The band that the present invention proposes is surely followed closely hot rolled circular steel and production method thereof, and is simple in structure, easy to process, with low cost, and result of use is extremely desirable.Sucker rod round steel band is surely followed closely, and acts on the centralizer position, and centralizer is hung on the round steel of the steady nail of band, combines firmly with round steel, and the back centralizer that at high temperature expands can not glide yet, and improves the application life of sucker rod and oil well greatly.Bring good economic benefits for sucker rod enterprise and oil field.
Description of drawings:
Below in conjunction with accompanying drawing this invention is described in detail.
Fig. 1 is the steady nail of a band hot rolled circular steel schematic diagram
Fig. 2 is the steady nail of a band sucker rod work schematic diagram;
Fig. 3 is the Roller Machining schematic diagram.
Fig. 4 is that schematic diagram is produced in steel rolling.
Wherein: 1, steady nail, 2, centralizer, 3, the oil well wall, 4, sucker rod, 5, up-down rollers surely follows closely spacing, 6, single roll surely follows closely spacing, 7, the electrode prefix, 8, recessed poor, 9, homalocephalus, 10, groove, 11, outlet
Specific implementation:
As shown in Figure 1: have proportional spacing, periodic steady nail 1 in the both sides of sucker rod 4, surely follow closely 1 shape and can design by cuboid with the signal of steady nail hot rolled circular steel.As shown in Figure 2 with steady nail sucker rod work signal: the steady nail on the centralizer 2 on machined grooves and the sucker rod matches, and considers to combine firm needs with round steel, and the length direction of cuboid is perpendicular to the length direction of sucker rod.Because the influence of the deformation rule of the operation of rolling, finished form is the ladder type wimble structure.Steady nail 1 size is wanted suitably, and especially steady staple height should guarantee to tangle centralizer 2, guarantees that again the intensity of steady nail place round steel reaches standard-required.
Electrode prefix that can reference is shaped as rectangle, each specification length is as follows:
The electrode prefix size of the steady nail of band hot rolled circular steel
| The round steel specification | Φ16 | Φ19 | Φ22 | Φ25 | Φ28 |
| Wide | 4 | 4 | 4 | 4 | 4 |
| Long | 13 | 16 | 19 | 21 | 21 |
| High | 2.5 | 2.5 | 2.5 | 3 | 3 |
Annotate: the putting position of surely following closely in roll is surely to follow closely length to vertical with the length of rolled piece direction.
The steady nail of downside is shut out by lower roll, and the steady nail of upside is shut out by top roll, and the size that single roll is surely followed closely spacing 6 depends on the girth of roll, can have one or more lower rolls that surely nail on surely to follow closely the size of spacing 5 and depend on the relative distance of installing bottom roll groove 8 on single roller.
The relative distance of top and bottom rolls groove 8 depends on the processing and the installation of roll.As the Roller Machining schematic diagram: during the groove 8 of the steady nail of processing top and bottom rolls, look for the object of reference of definite up-down rollers installation site, what we selected is the homalocephalus 9 of roll, two roll homalocephalus, 9 plane parallel are in ground up and down, and electrode prefix 7 is beaten on the groove 10 of this roll perpendicular to the ground direction.
Produce schematic diagram as steel rolling: the groove 8 of top and bottom rolls made progress simultaneously when roll was installed, and installed at homalocephalus 9 places and connect axle.
For the 9 position difference angle of homalocephalus up and down that guarantee roll are not more than 15 degree.Two roll people tooth case homalocephalus plane parallel are in ground, again with its kneading up and down.Error is not more than two teeth.
The diameter of outlet 11 is thicker a little than the round steel that rolls with diameter.Prevent the steel rolling fault of push pipe.
