Accompanying drawing explanation
Fig. 1 is the flow process chart of embodiment 1.
Fig. 2 is the flow process chart of embodiment 2.
Detailed description of the invention
With embodiment, the present invention is elaborated below in conjunction with the accompanying drawings.
Embodiment 1:
Referring to Fig. 1, shown in figure is the forming method of a kind of carpenter's auger embryo.Bore embryo and there is drill bit segment, drill pipe section and drillstock section.Include following steps,
Step S1, it is provided that steel raw material.Depending on the choice of material of steel raw material is according to the requirement of order party, the restriction that the present embodiment is not fixed for the kind of steel.
Step S2, pulls into cylindrical long section in the way of wire drawing (stretching) by steel raw material.Diameter 30-50 bigger than the diameter of the drill bit finished product silk of cylindrical long section.(the present embodiment offer is only carpenter's auger embryo, the follow-up step sequences such as grinding machine polishing of also wanting, therefore, certain surplus need to be left).
Step S3, fracture.With reference to the length of drill bit finished product, by blank cutter, long for cylinder section is intercepted into a section fracture 1.Illustrate is, it is contemplated that directly gets on fracture and bores the drill bit segment of embryo and be molded other parts, therefore, the length of length drill bit the to be longer than finished product of fracture.
Step S4, uses the first forge die to forge and press fracture head.First forge die has the first upper mold 2 and is in the lower mold 3 below the first upper mold.In the way of concave downward, the accommodating cavity of cylinder is formed on the end face of lower mold.Accommodating cavity diameter more than the diameter of fracture because the diameter of accommodating cavity is identical with the diameter of the drill bit segment boring embryo, and the diameter of fracture is identical with the diameter of the drill pipe section of brill embryo, and the diameter of drill bit segment is naturally larger than the diameter of drill pipe section.In the way of upwards caving in, form the via of cylinder on the bottom surface of lower mold, the diameter of via, fracture diameter identical with the diameter of drillstock section of brill embryo.Via is connected with accommodating cavity.Being formed with the first forging and stamping head on the bottom surface of the first upper mold, the working face of the first forging and stamping head is and houses the plane that cavity floor is paralleled.Fracture head is placed in accommodating cavity, and in the middle part of fracture and afterbody passes downwards from via, after move down the first upper mold, utilize the first forging and stamping head that fracture head forges into cylindrical head, the making base portion being similar in engraving a seal.Meanwhile, sampling the 3rd forge die carries out the shaping of contracting bar to form the drillstock section boring embryo to fracture afterbody.Unprocessed fracture stage casing is the drillstock section boring embryo.
Step S5, uses the second forge die to forge and press cylindrical head.Second forge die has the second upper mold 4 and is in the lower mold below the second upper mold.Lower mold in lower mold i.e. step S4, this step simply changes corresponding upper mold.The second forging and stamping head it is formed with on the bottom surface of the second upper mold, the working face of the second forging and stamping head is corresponding with the shape of the drill bit segment of brill embryo, and (drill bit segment has drill bit base portion, apex point, circumferential cutting edge and main cutting edge, apex point system is placed in the end face center of drill bit base portion, circumferential cutting edge system is placed in the cylindrical of drill bit base portion, main cutting edge system connects apex point and circumferential cutting edge, and the working face of the second forging and stamping head is formed with the jog contrary with drill bit base portion, apex point, circumferential cutting edge and main cutting edge shape.Briefly, the ground square shape negative and positive that the working face of the second forging and stamping head is corresponding with drill bit segment are contrary).Move down the second upper mold, utilize the second forging and stamping head that cylindrical head is forged into drill bit segment, the seal cutting pattern being similar in engraving a seal.
Whole carpenter's auger embryo completes.
Embodiment 2:
Relative to embodiment 1, the forming method of a kind of carpenter's auger embryo that the present embodiment provides, mainly in the carpenter's auger embryo being relatively large in diameter, see Fig. 2.Because being relatively large in diameter of carpenter's auger embryo, it is contemplated that difficulty and the cost of wire drawing (stretching) have promoted.Therefore, save this step of wire drawing (stretching).Method includes following steps.
Step S1, it is provided that 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 more than the length of the drill bit segment of drill bit finished product, the entire length of drill bit finished product can be not more than.
Step S3, uses the first forge die to forge and press fracture.First forge die has the first upper mold 2 and is in the lower mold 3 below the first upper mold.In the way of concave downward, the accommodating cavity of cylinder is formed on the end face of lower mold.Accommodating cavity diameter more than the diameter of fracture because the diameter of accommodating cavity is identical with the diameter of the drill bit segment boring embryo.In the way of concave downward, the blind hole of cylinder is formed on the bottom surface of accommodating cavity.The diameter of blind hole, fracture diameter with bore embryo drillstock section identical.Being formed with the first forging and stamping head on the bottom surface of the first upper mold, the working face of the first forging and stamping head is and houses the plane that cavity floor is paralleled.Fracture is placed in accommodating cavity, after move down the first upper mold, utilize the first forging and stamping head that fracture forges into cylindrical head and cylindrical tail portion, the making base portion being similar in engraving a seal.
Step S4, uses the second forge die to forge and press cylindrical head.Second forge die has the second upper mold 4 and is in the lower mold below the second upper mold.Lower mold in lower mold i.e. step S3, this step simply changes corresponding upper mold.The second forging and stamping head it is formed with on the bottom surface of the second upper mold, the working face of the second forging and stamping head is corresponding with the shape of the drill bit segment of brill embryo, and (drill bit segment has drill bit base portion, apex point, circumferential cutting edge and main cutting edge, apex point system is placed in the end face center of drill bit base portion, circumferential cutting edge system is placed in the cylindrical of drill bit base portion, main cutting edge system connects apex point and circumferential cutting edge, and the working face of the second forging and stamping head is formed with the jog contrary with drill bit base portion, apex point, circumferential cutting edge and main cutting edge shape.Briefly, the ground square shape negative and positive that the working face of the second forging and stamping head is corresponding with drill bit segment are contrary).Move down the second upper mold, utilize the second forging and stamping head that cylindrical head is forged into drill bit segment, the seal cutting pattern being similar in engraving a seal.
Step S5, it is provided that drill pipe section and drillstock section, is connected with drill pipe section in a welding manner by drill bit segment.
Below only have expressed embodiments of the present invention, it describes more concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
