Compared with the prior art, the utility model discloses an advantage lies in with positive effect, the utility model discloses a change the structure of traditional reamer, set up the cutting edge of two relative settings through the one end at the drillstock, make the cutting edge be umbelliform cover and on the drillstock, through the rotation of cutting edge, produce certain wind -force, solved the improper problem of traditional chip removal, increased the life of reamer, and then improved production efficiency.
Description
Technical field
The utility model belongs to pipe elevator process equipment field, relates to reamer, particularly relates to a kind of pipe elevator reamer.
Background technology
Pipe elevator is the specific purpose tool of tubing string of hoisting in petroleum drilling and mining or decline.In the process of pipe elevator, when especially processing endoporus, the general fluted drill that all adopts is processed, to process ∮ 120, the degree of depth is the endoporus of 180mm is example, first on rough forging, bores bottom outlet with ∮ 30 fluted drill, then the reaming of ∮ 80 fluted drill is adopted, be drilled into the degree of depth like this more than after 100mm, due to chip reason, chip removal can be caused not smooth.Need be fallen back drill bit chip removal repeatedly, as not in time, very easily causes land to squeeze bits, damage land, and along with the degree of depth increases, squeeze bits and seriously even cause drill bit to drill, twist off drill bit and drillstock, it is unfavorable to produce production and processing, and then reduces production efficiency.
Utility model content
The utility model for the crowded bits freely do not caused because of chip removal during above-mentioned fluted drill processing pipe elevator and then the technical problem causing bit damage, propose a kind of reasonable in design, structure is simple, the with low cost and pipe elevator reamer that chip removal is effective.
In order to achieve the above object, the technical solution adopted in the utility model is, the utility model provides a kind of pipe elevator reamer, comprise drillstock, one end of described drillstock is provided with blade, described edge tilted is arranged on one end of drillstock, and one end of described drillstock is provided with two blades be oppositely arranged, and one end of described blade extends to outside drillstock.
As preferably, the angle of inclination of described blade is 45 °.
As preferably, the material of described blade is white steel.
As preferably, described drillstock is provided with taper shank away from the other end of blade, and the tapering of described taper shank is No. 5, Mohs.
Compared with prior art, advantage of the present utility model and good effect are,
1, the utility model is by changing the structure of traditional reamer, by arranging two blades be oppositely arranged in one end of drillstock, blade is made to be that umbrella covers on drillstock, by the rotation of blade, produce certain wind-force, solve traditional chip removal problem improperly, add the service life of reamer, and then improve production efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The structural representation of the pipe elevator reamer that Fig. 1 provides for embodiment 1;
Above in each figure, 1, drillstock; 2, blade; 21, fixed part; 22, extension; 3, reinforcement; 4, taper shank.
Detailed description of the invention
In order to more clearly understand above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with drawings and Examples, the utility model is described further.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
Set forth a lot of detail in the following description so that fully understand the utility model, but, the utility model can also adopt and be different from other modes described here and implement, and therefore, the utility model is not limited to the restriction of the specific embodiment of prospectus below.
Embodiment 1, as shown in Figure 1, the present embodiment provides a kind of pipe elevator reamer, comprise drillstock 1, drillstock 1 is the steel of simple column type, consistent with shape with the structure of the drillstock of traditional fluted drill, one end of drillstock 1 is provided with blade 2, the global shape of blade 2 is cuboid, blade 2 is inclined at one end of drillstock 1, one end of drillstock 1 is provided with two blades be oppositely arranged 2, one end of blade 2 extends to outside drillstock 1, blade 2 can be divided into two parts, a part is for being welded on the one end on drillstock 1, this part can be called fixed part 21, another part is the one end of extending outside drillstock 1 is extension 22, like this, two blades 2 just cover on one end of drillstock 1 in umbrella.
By above-mentioned setting, specifically adding man-hour, blade 2 rotates and carries out reaming, namely cuts the rear that the gap of chip between two blades 2 of getting off flows to blade 2, because two blades 2 are inclined on handle of a knife 1, it is when rotating, certain wind-force can be produced chip is dispelled, solve the possibility of squeezing bits, simultaneously, wind-force provides certain cooling effect also can to blade 2, and then improves service life.
In order to improve the chip removal effect of blade 2, therefore in the present embodiment, blade 2 is 45 ° with the angle of horizontal direction, and namely the angle of inclination of blade 2 is 45 °, simultaneously, in order to wind effect, the length that extension 22 exceeds drillstock 1 is 15-20mm, meanwhile, has also added the reinforcement 3 of arc between extension 22 and drillstock 1, reinforcement 3, except providing except high strength for blade 2, also effectively can increase wind-force.
In order to improve the cutting effect of blade 2, in the present embodiment, the material of blade 2 is white steel preferably, specifically selects specification to be the white steel of 16*16 or 20*20.
Conveniently install, provide the stability of drillstock simultaneously, at drillstock 1, the other end of blade 2 is provided with taper shank 4, the tapering of taper shank 4 is No. 5, Mohs.
The above; it is only preferred embodiment of the present utility model; it is not restriction the utility model being made to other form; the Equivalent embodiments that any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as equivalent variations is applied to other field; but everyly do not depart from technical solutions of the utility model content; according to any simple modification, equivalent variations and remodeling that technical spirit of the present utility model is done above embodiment, still belong to the protection domain of technical solutions of the utility model.
