Abstract
The invention discloses a quick and precise manufacturing method for a twist drill extension bar. The method comprises the following steps: 1) a hollow bent pipe is selected; the inner diameter of the hollow bent pipe is larger than the diameter of a drill bit; and the section size is invariable; 2) a steel wire is primarily straightened, and is held by an air drill; under high-speed rotating speed of a main shaft of the air drill, the fine steel wire is suffered from the effect of force in the hollow bent pipe to generate plastic deformation; and 3) two ends of the steel wire are exchanged for straightening again. The method only needs one hollow bent pipe; the air drill holds one general fine steel wire; and under high-speed rotating speed of the main shaft of the air drill, the fine steel wire is suffered from the effect of force in the hollow bent pipe to generate plastic deformation to form a straight extension bar. The method is few in needed tools, simple in operation and high in manufacturing efficiency; and the manufactured extension bar is excellent in straightness, can bear higher cutting force, can largely reduce the production cost, and improves the production efficiency.
Description
Technical field
The present invention relates to drilling of the spare part in semiclosed or narrow space（Drilling）The technical field of processing, specifically one
Plant the fast precise manufacture method of drill bit extension bar.
Background technology
Drilling is to rivet a kind of basic technology in assembling process.When section structure framework is driveed the rivets, some special knots
Structure causes air drill cannot be introduced into, or vertical drilling cannot be carried out in boring procedure, it is then desired to use lengthening drill bit complete
Boring work in these specific work environments and region.
In bore operation, more conventional drill bit has Φ 3.1mm, Φ 4.1mm equal-specifications, in the range of relevant criterion
There is certain length or overlength fluted drill, but as its blade increases with the increase of fluted drill length, in complicated narrow sky
Between when drilling, the drill lip at non-drilling position will touch product, cause damaged products.Additionally, buying long handle or overlength handle fiber crops
Flower is drilled to this and also will be higher by several times than the straight shank twist drill of same specification.
In traditional practice, intercept the reinforcing bar of certain length first according to actual needs, be then placed on operating board,
Rotate while progressively struck reinforcing bar directly with hammer, due to by manually-operated restriction, one point one being needed during beaing
That what is put beats reinforcing bar, not only time-consuming, and cannot ensure the linearity of reinforcing bar, and effect is not satisfactory.With carrier rocket it is highly dense
The development and production of degree, in riveting nacelle assembling, the increase year by year of task amount, the usage amount of lengthening drill bit are consequently increased, and pass
The extension bar manufacture method of system cannot meet the demand of batch making.
Currently without the explanation or report that find technology similar to the present invention, money similar both at home and abroad is also not yet collected
Material.
The content of the invention
For the problem that the conventional fabrication method of drill bit extension bar is present, propose that a kind of fast precise makes the work of extension bar
Process, solves that conventional fabrication method efficiency is low, and high labor intensive, level of skill have high demands, the extension bar straight line produced
The problems such as degree difference.
The present invention is achieved through the following technical solutions：A kind of fast precise makes the process of extension bar, including with
Lower step：
Step 1）Choose hollow bent pipe；
The internal diameter of the hollow bent pipe is bigger than bit diameter, and sectional dimension is constant；
Step 2）First alignment is carried out to steel wire；
The steel wire is accommodated using air drill, under the high speed rotation of air drill main shaft, finer wire is made by power in hollow bent pipe
With generation plastic deformation；
Step 3）Steel wire two ends are exchanged carries out alignment again.
Preferably, the step 1）The internal diameter of middle hollow bent pipe 5mm ~ 8mm bigger than bit diameter, sectional dimension are constant, protect
Card finer wire has enough spaces, bears optimal stress.
The present invention need to use a hollow bent pipe, air drill to accommodate a conventional finer wire compared with prior art, only,
Under the high speed rotation of air drill main shaft, finer wire is subject to the effect of power that plastic deformation occurs in heart bend pipe, and forms one straight
Extension bar.And, using instruments such as conventional air drill, hollow bent pipe, bench vices, uneven finer wire is bent in rotation status
Under, while being equably subject to circumferential extruding force, just linear state can be changed into by case of bending, and making becomes adding for drill bit
Stock.Making a high-precision extension bar only needs 1 minute, is applicable to batch making, and can significantly reduce production cost,
Most basic guarantee is provided for product development.
Description of the drawings
Fig. 1 is the process block diagram that a kind of fast precise of the present invention makes extension bar.
Specific embodiment
With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, some deformations and improvement can also be made.These belong to the present invention
Protection domain.
A kind of fast precise of the embodiment of the present invention makes the process of extension bar, comprises the following steps：
Step 1）Choose hollow bent pipe；
Before extension bar makes, it should be ensured that the internal diameter of hollow bent pipe 5mm ~ 8mm typically big than bit diameter, and sectional dimension is not
Become, otherwise will affect the fabricating quality of extension bar.
Step 2）First alignment is carried out to steel wire；
The steel wire is accommodated using air drill, under the high speed rotation of air drill main shaft, finer wire is made by power in hollow bent pipe
With generation plastic deformation；
Step 3）Steel wire two ends are exchanged carries out alignment again.
Original state before finer wire alignment, when first time bending hollow pipe is entered, near air drill chuck position because
Hollow inside pipe wall is not entered into, so reinforcing bar should be changed other end clamping after one bout back and forth by reinforcing bar, non-alignment portion is made
Divide into bend pipe alignment, i.e., after alignment one bout, steel wire two ends are exchanged, whole steel wire linearity control can be made to exist
0.01mm（Per 200mm）.Through the alignment of multi-round, the steel wire for originally bending is made as straight extension bar.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various modifications or modification within the scope of the claims, this not shadow
Ring the flesh and blood of the present invention.
