Fig. 1 is referred to, shown in figure is a kind of forming method of carpenter's auger embryo.Boring embryo has drill bit segment, drill pipe section and drillstock
Section.Include following steps,
Step S1 provides steel raw material.The choice of material of steel raw material is depending on the requirement of order party, and the present embodiment is for steel
The kind of material does not have fixed limitation.
Step S2, with wire drawing（It stretches）Mode steel raw material is pulled into cylindrical long section.The diameter ratio of cylindrical long section
The diameter of drill bit finished product is 30-50 big.（Provided in this embodiment is only carpenter's auger embryo, subsequently also wants the step sequence such as grinding machine polishing,
Therefore it need to there are certain surpluses）.
Step S3, fracture.With reference to the length of drill bit finished product, by blank cutter by cylindrical long section interception at the disconnected of a section
Material 1.What is illustrated is, it is contemplated that the drill bit segment and molding other parts for boring embryo are directly got on fracture, therefore, the length of fracture is wanted
It is longer than the length of drill bit finished product.
Step S4 forges and presses fracture head using the first forge die.First forge die have the first upper mold 2 and
Lower die 3 in the first lower part of upper die.Cylindrical accommodating cavity is formed on the top surface of lower die in a manner of to lower recess.It is accommodating
The diameter of cavity is more than the diameter of fracture, because the diameter of accommodating cavity is identical as the diameter of drill bit segment of embryo is bored, and breaks
The diameter of material is identical as the diameter of drill pipe section of embryo is bored, and the diameter of drill bit segment is naturally larger than the diameter of drill pipe section.The bottom surface of lower die
On form cylindrical via in a manner of being recessed upwards, the diameter of via, the diameter of fracture and the drillstock section for boring embryo diameter
It is identical.Via is connected with accommodating cavity.The first forging and stamping head, the working face of the first forging and stamping head are formed on the bottom surface of first upper mold
For the plane parallel with accommodating cavity floor.Fracture head is placed in accommodating cavity, and in the middle part of fracture and tail portion is from via
Be pierced by downwards, after move down the first upper mold, fracture head is forged into cylindrical head using the first forging and stamping head, similar to engraving a seal
In making base portion.Meanwhile it sampling third forge die and the molding of contracting bar is carried out to form the drillstock section for boring embryo to fracture tail portion.Not
The fracture stage casing of processing is the drillstock section for boring embryo.
Step S5 forges and presses cylindrical head using the second forge die.Second forge die has the second upper mold 4
And the lower die in the second lower part of upper die.Lower die in lower die, that is, step S4, this step only replace corresponding upper mold.On second
The second forging and stamping head is formed on the bottom surface of mould, the working face of the second forging and stamping head is corresponding with the shape of drill bit segment of embryo is bored（Drill bit
There is section drill bit base portion, apex point, circumferential cutting edge and main cutting edge, apex point system to be placed in the end face center of drill bit base portion, and circumference is cut
The outer circle that sword system is placed in drill bit base portion is cut, main cutting edge system connects apex point and circumferential cutting edge, and second forges and presses on the working face of head
It is formed with the jog opposite with drill bit base portion, apex point, circumferential cutting edge and main cutting edge shape.Briefly, the second forging and stamping
Both working face and drill bit segments of head corresponding ground square shape negative and positive are opposite）.The second upper mold is moved down, will be justified using the second forging and stamping head
Cylindrical head forges into drill bit segment, similar to the seal cutting pattern in engraving a seal.
Entire carpenter's auger embryo is completed.
Embodiment 2：
Relative to embodiment 1, a kind of forming method of carpenter's auger embryo provided in this embodiment, mainly in the wood being relatively large in diameter
Work bores embryo, sees Fig. 2.Because carpenter's auger embryo is relatively large in diameter, it is contemplated that wire drawing（It stretches）Difficulty and cost also promoted.
Therefore save wire drawing（It stretches）This step.Method includes following steps.
Step S1 provides steel raw material.
Step S2, fracture.This step, the drill bit segment length of the length reference drill bit finished product of fracture 1, it is only necessary to be more than drill bit at
The length of the drill bit segment of product can be not more than the entire length of drill bit finished product.
Step S3 forges and presses fracture using the first forge die.First forge die has the first upper mold 2 and is in
The lower die 3 of first lower part of upper die.Cylindrical accommodating cavity is formed on the top surface of lower die in a manner of to lower recess.Accommodating cavity
Diameter be more than the diameter of fracture because the diameter of accommodating cavity is identical as the diameter of drill bit segment of embryo is bored.Accommodating cavity
Bottom surface on cylindrical blind hole is formed in a manner of to lower recess.The drillstock section of diameter of blind hole, the diameter of fracture and brill embryo
It is identical.The first forging and stamping head is formed on the bottom surface of first upper mold, the working face of the first forging and stamping head is equal with accommodating cavity floor
Capable plane.Fracture is placed in accommodating cavity, after move down the first upper mold, using first forging and stamping head fracture is forged into cylinder
Head and cylindrical tail portion, similar to the making base portion in engraving a seal.
Step S4 forges and presses cylindrical head using the second forge die.Second forge die has the second upper mold 4
And the lower die in the second lower part of upper die.Lower die in lower die, that is, step S3, this step only replace corresponding upper mold.On second
The second forging and stamping head is formed on the bottom surface of mould, the working face of the second forging and stamping head is corresponding with the shape of drill bit segment of embryo is bored（Drill bit
There is section drill bit base portion, apex point, circumferential cutting edge and main cutting edge, apex point system to be placed in the end face center of drill bit base portion, and circumference is cut
The outer circle that sword system is placed in drill bit base portion is cut, main cutting edge system connects apex point and circumferential cutting edge, and second forges and presses on the working face of head
It is formed with the jog opposite with drill bit base portion, apex point, circumferential cutting edge and main cutting edge shape.Briefly, the second forging and stamping
Both working face and drill bit segments of head corresponding ground square shape negative and positive are opposite）.The second upper mold is moved down, will be justified using the second forging and stamping head
Cylindrical head forges into drill bit segment, similar to the seal cutting pattern in engraving a seal.
Step S5 provides drill pipe section and drillstock section, and drill bit segment is connect in a welding manner with drill pipe section.
Embodiments of the present invention, the description thereof is more specific and detailed are only expressed above, but can not therefore be understood
For the limitation to patent of invention range.It should be pointed out that for those of ordinary skill in the art, not departing from this hair
Under the premise of bright design, various modifications and improvements can be made, these are all within the scope of protection of the present invention.Therefore, this hair
