Description
Technical field
The utility model is related to for oil, gas drilling and the junk mill of underground work, especially a kind of spiral wedged bottom
Junk mill.
Background technology
Junk mill is a kind of brill mill class instrument for being mainly used in well workover and underground work, and its function includes grinding junk, brill
Bridging plug etc..Existing junk mill is broadly divided into flat-bottom grind shoes and the major class of concave bottom milling shoe two.To the various different junk millings in underground and not
Bored with species bridging plug during grinding, the structure type of junk mill directly affects brill mill operating efficiency；Conventional junk mill is boring honed
Cheng Zhong, tool-face contact area is larger, and junk mill cutting edge is difficult to wedging milling object, so as to cause milling speed very low, greatly
It has impact on duty cycle；Arrange, the product information identified on junk mill body can be caused simultaneously because the metal fragment of milling is counter
Substantial amounts of abrasion, many junk mills go out after well, and product information can not be recognized, and the analysis and data statistics to the operation later stage are caused
Inconvenience.
The content of the invention
Based on above technical problem, the utility model provides a kind of spiral wedged bottom junk mill, so as to solve existing junk mill
Cause the low technical problem of operating efficiency because milling head contact area is larger, junk mill cutting edge is difficult to wedging milling object.
The technical solution adopted in the utility model is as follows：
A kind of spiral wedged bottom junk mill, includes the body of junk mill, and the body top is provided with milling head, the milling head
Spiral shape milling wing is provided with, the working face of the spiral shape milling wing is helicoid, and the helicoid is relative to body
Inclination angle gradually increase.
Further, the lift angle of the helicoid, which is 5 °~10 °, makes helicoid gradually increase relative to the inclination angle of body.
Further, runner is provided with the body, the flow passage has spray-hole, and the spray-hole is arranged on institute
State between spiral shape milling wing.
Further, the milling head outer surface is provided with chip area.
Further, the outer surface of the body lower end is provided with thread.
Further, the body center outer surface is provided with the annular groove for indicating product information.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
In milling head operation process, milling wing remains relatively conventional flat-bottom grind shoes and concave bottom milling shoe is less connects
Contacting surface is accumulated, and makes the easy wedging milling object of cutting edge of junk mill spiral shape milling wing, improves milling speed；With spiral shape milling
Wing gradually gos deep into milling object, using spiral shape working face, can be gradually increased milling face, is improving the same of milling speed
When reach expected milling effect；By setting annular groove on body, anti-row's chip can be reduced to body concentrated wear, and reach
Protect the purpose of annular groove local product mark.

Embodiment
All features disclosed in this specification, can be with any in addition to mutually exclusive feature and/or step
Mode is combined.
The present invention is elaborated below in conjunction with the accompanying drawings.
A kind of spiral wedged bottom junk mill, includes the body 1 of junk mill, and the top of body 1 is provided with milling head 8, the milling
Spiral shape milling wing 2 is provided with first 8, the working face of the spiral shape milling wing 2 is helicoid 9, the phase of helicoid 9
Gradually increase for the inclination angle of body 1；
The lift angle of the helicoid 9 is 5 °~10 °；
Runner 7 is provided with the body 1, the runner 7 is communicated with spray-hole 3, and the spray-hole 3 is arranged on the spiral shell
Between rotation shape milling wing 2；
Chip area 4 is provided with the outer surface of milling head 8；
The outer surface of the lower end of body 1 is provided with thread 6；
The center outer surface of body 1 is provided with the annular groove 5 for indicating product information.
Below, come to be described in further details the utility model in conjunction with specific embodiments.
The course of work of the present utility model：The cutting edge wedging milling object of spiral shape milling wing 2, with spiral shape milling
Wing 2 gradually gos deep into milling object, and junk mill makes milling object carry out being passed through in abundant milling, runner 7 on spiral shape working face
Highly pressurised liquid, highly pressurised liquid sprays by runner 7 from spray-hole 3, the leftover after milling is followed highly pressurised liquid from the row of chip area 4
Go out, eventually arrive at the effect of quick milling.
Specific embodiment
A kind of spiral wedged bottom junk mill, includes the body 1 of junk mill, and the top of body 1 is provided with milling head 8, the milling
