Description
Technical field
the utility model relates to a kind of efficient impregnated type neck eye junk mill, belongs to downhole tool technical field.
Background technology
prior art CN201420340469 " a kind of abrasionproof piloted mill " disclosed neck eye junk mill, in the course of the work, there is the heat that grinding produces cannot discharge the structure of main cutting edge and neck eye cutting edge in time, neck eye cutting edge easily and tube wall be sticked together; Main cutting edge and junk mill body are one, make difficulty, and the carbide alloy on welding cutting edge needs special frock to ensure that solder side is in level, otherwise are difficult to guarantee and reach designing requirement.
Utility model content
the purpose of this utility model is, provides a kind of efficient impregnated type neck eye junk mill.To solve existing neck eye junk mill, in use easily eccentric wear, easily adhesion and alloy cutting edge arrange the technical problem of difficulty.
the technical solution of the utility model:
a kind of efficient impregnated type neck eye junk mill, comprise body, the shape of body is tubulose; The endoporus of pipe is hydrophthalmia, and body epimere is provided with joint screw thread, and body stage casing is provided with knife plate parts, and under body, section surface is provided with circulating water chennel and alloying pellet.
in aforementioned structure, described knife plate parts are uniform along body cylindrical, and knife plate parts weld with body cylindrical; Knife plate parts comprise knife plate and alloy cutting edge.
in aforementioned structure, described alloy cutting edge is made up of staggered one group of eight rib alloy wedge, and eight rib alloy wedges are provided with cutting edge, and the cutting anterior angle of cutting edge is 6 ~ 10 °, and back angle is 4 ~ 8 °.
in aforementioned structure, described hydrophthalmia is the blind hole of bottom for closing, and blind via bottom is provided with hole for water spraying.
compared with prior art, the circulating water chennel at neck eye cutting edge place of the present utility model can dispel the heat in time, prevents neck eye cutting edge and tubing string adhesion; This product increases the grinding speed of neck eye junk mill, increases work efficiency, overcomes the deficiencies in the prior art.

Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
a kind of efficient impregnated type neck eye junk mill, as shown in figures 1-4: comprise body 2, the shape of body is tubulose; The endoporus of pipe is hydrophthalmia 5, and body epimere is provided with joint screw thread 1, and body stage casing is provided with knife plate parts 3, and under body, section surface is provided with circulating water chennel 6 and alloying pellet 4.Knife plate parts are uniform along body cylindrical, and knife plate parts weld with body cylindrical; Knife plate parts comprise knife plate 8 and alloy cutting edge 9.Alloy cutting edge is made up of staggered one group of eight rib alloy wedge, and eight rib alloy wedges are provided with cutting edge, and the cutting anterior angle of cutting edge is 6 ~ 10 °, and back angle is 4 ~ 8 °.Hydrophthalmia is the blind hole of bottom for closing, and blind via bottom is provided with hole for water spraying 7.
Embodiment
the efficient neck eye junk mill of this example is made up of the alloying pellet 4 of main body 2, knife plate parts 3, surfacing.Body 2 is made up of joint screw thread 1, hydrophthalmia 5, circulating water chennel 6, hole for water spraying 7; Body 2 forms main cutting edge by welding knife plate parts 3, body 2 forms neck eye cutting edge by surfacing alloying pellet 4.
as shown in Figure 3, the mode that main cutting edge adopts knife plate parts 4 to weld with body 2 is formed, compared with traditional integrated cutting edge: knife plate 8 structure of the present utility model is more simple, convenient in machining; Metal has easily deformable feature in heat treatment process, and knife plate is easier to control the deflection in heat treatment process.Knife plate parts 4 adopt welding alloy cutting edge 9 on knife plate 8 to be formed, in welding: knife plate 8 can make solder side be easier to be horizontal, and facilitates the arrangement of alloy cutting edge 9 and welds.By to the understanding of cutting anterior angle and relief angle, choose eight rib alloy wedges as alloy cutting edge 9, finally form 8 ° and cut anterior angle, 6 ° of back angles, have high, the nonabradable feature of grinding efficiency; Alloy cutting edge 9 adopts staggered mode in arrangement, in working angles, more increases the area of cut.
as shown in Figure 4, neck eye cutting edge adopts circulating water chennel design, by processing class spline structure on body 2, forms circulating water chennel at key position surfacing alloying pellet 4, prevent the high temperature produced in the process of grinding from cannot leave in time, make neck eye cutting edge and tube wall adhesion.
this example is when normally working, and main cutting edge takes into account the effect of righting, and circulation fluid flows out from hydrophthalmia 5 through hole for water spraying 7 and circulating water chennel 6; Main cutting edge is formed with body by welding knife plate parts 4; Neck eye cutting edge utilizes import alloying pellet 5 surfacing on body 1 to be formed, and neck eye cutting edge and main cutting edge form complementation in cutting scope.
