Consult Fig. 7,8, and look back in the lump Fig. 3, the first preferred embodiment of the forming method of the spherical type head of hand-held tool of the present invention, to utilize the first preferred embodiment of the shaped device 2 of the spherical type head of above-mentioned hand-held tool to be carried out, so described in the present embodiment and apparatus structure, be exactly the preferred embodiment of the shaped device 2 of the spherical type head of above-mentioned hand-held tool, so do not repeated at this.
First shown in step 31, utilize cutting apparatus to prepare a column blank 41 of preseting length, this blank 41 has a contrary first end 411 and one second end 412.In this preferred embodiment, the hexagonal cylinder that this blank 41 is long 27mm.
Next, as shown in step 32, this blank 41 is placed in to the peristome 213 of the chamfered bore 212 of this chamfering master mold 211, coordinates this chamfering male model 215 and form a chamfering 413 matching with this first chamfered section 214 in this first end 411 and this second end 412.In this preferred embodiment, first the first end of this blank 41 411 to be inserted in this peristome 213 towards this first chamfered section 214, and form chamfering 413 in this first end 411, and then the second end 412 of this blank 41 is inserted in this peristome 213 towards this first chamfered section 214, and form chamfering 413 in this second end 412.
Consult Fig. 7,8, and look back in the lump Fig. 4, then, as shown in step 33, the holding part 223 that the first end 411 of blank 41 that forms chamfering 413 is placed in to the elongated hole 222 of this elongation master mold 221 towards these elongation master mold 221 directions, coordinates this elongation male model 226 to forge this blank 41 and makes this blank 41 be shaped to a pre-forging 42.
This pre-forging 42 comprises a first paragraph conforming to this elongated portion 225 421, a second segment 422 conforming to this holding part 223, and one conform to this contracting bundle portion 224 and be pushing and drawing shape and be connected this second segment 422 and this first paragraph 421 push away the section of pulling out 423.In this preferred embodiment, this first paragraph 421 is 12mm with this total length that pushes away the section of pulling out 423, and the length of this second segment 422 is 20mm, and the external diameter of this first paragraph 421 is less than the external diameter of this second segment 422.
Consult Fig. 7, 8, and look back in the lump Fig. 5, then, as shown in step 34, the first paragraph of this pre-forging 42 421 is placed in to the print hole 232 of this printing master mold 231 towards these printing master mold 231 directions, utilize the guidance part 233 of this print hole 232 and be installed in portion 234 and this pre-forging 42 push away the section of pulling out 423 and first paragraph 421 matches, so that this pre-forging 42 is positioned in this print hole 232, coordinate and be formed at this first print module 236 and this this second segment 422 of the second print module 237 clippings of setting picture and text 238, and on this second segment 422, form corresponding setting picture and text 238, then, this first print module 236 can be separated from each other with this second print module 237, in print hole 232 with this printing master mold 231 certainly, eject this pre-forging 42.
Consult Fig. 7, 8, and look back in the lump Fig. 6, finally, as shown in step 35, again this pre-forging 42 is placed in to the locating hole 242 of this swaging master mold 241, and make the first paragraph 421 of this pre-forging 42 protrude this locating hole 242 towards these swaging male model 245 directions, utilize the location division 243 of this locating hole 242 and push away the portion of pulling out 244 to locate the second segment 422 of this pre-forging 42 and to push away the section of pulling out 423, coordinate these pressure ram 248 these first paragraphs 421 of extruding to make this first paragraph 421 contraction in lengths, be connected with and form one the connecting portion 424 that pushes away the section of pulling out 423 in this, and one be connected with in this connecting portion 424 and push away the ball-type head 425 of one end of the section of pulling out 423 away from this.In this preferred embodiment, this pushes away the section of pulling out 423 is 10mm with length of this connecting portion 424 and this ball-type head 425, and this second segment 422, the total length that pushes away the section of pulling out 423 and this connecting portion 424 and this ball-type head 425 are 30mm.
Make this blank 41 coordinate this chamfer mould 21, extend mould 22, print die 23 according to above-mentioned steps, and this swaging mould 24, utilize these blank 41 length variations to replace cutting processing procedure, not only can effectively reduce equipment and cost of material, reduce process time, can also promote bulk strength.
Consult Fig. 9, 10, the second preferred embodiment of the shaped device 2 of the spherical type head of hand-held tool of the present invention is roughly identical with this first preferred embodiment, not identical place is: this shaped device 2 also comprise one with the spaced bending mold 26 of this swaging mould 24, and this chamfering male model 215 of this chamfer mould 21 is formed with an and section relative with this chamfered bore 212 and is hexagonal axis hole 216, this axis hole 216 has the axle hole identical with this peristome 213, an aperture 217, and one be formed at second chamfered section 218 of this axle hole 217 away from a side of this peristome 213.And this bending mold 26 comprise one with the spaced bending master mold 261 of this swaging mould 24, and one can this bending master mold 261 moves back and forth relatively bending male model 262.
Consult Figure 11,12, and look back in the lump Fig. 9, the second preferred embodiment of the forming method of the spherical type head of hand-held tool of the present invention, to utilize the second preferred embodiment of the shaped device 2 of the spherical type head of above-mentioned hand-held tool to be carried out, so described in the present embodiment and apparatus structure, be exactly the second preferred embodiment of the shaped device of the spherical type head of above-mentioned hand-held tool, so do not repeated at this.
The second preferred embodiment of the forming method of the spherical type head of hand-held tool of the present invention is roughly similar to this first preferred embodiment, different places are: also comprise a step 36 being connected in after step 35, utilize the second segment 422 of these bending mold 26 these pre-forging 42 of bending.
Due to the forming method of spherical type head and second preferred embodiment of shaped device 2 of hand-held tool of the present invention, roughly similar to the forming method of spherical type head and first preferred embodiment of shaped device 2 of this hand-held tool, therefore, except reaching effect identical with this first preferred embodiment, utilize this second chamfered section 218 of this chamfering male model 215, can forge once and just can form chamfering 413 at the first end of this blank 41 411 and the second end 412 simultaneously, and more effectively shorten process time.
Moreover, can also be by step 36 the bending master mold 261 and bending male model 262 with this bending mold 26, bend the second segment 422 of this pre-forging 42, can make this second segment 422 form one and be connected with the bar portion 426 that pushes away the section of pulling out 423 in this, and one push away the kink 427 of one end outward of the section of pulling out 423 by this bar portion 426 away from this, integrate and forge and bending processing procedure with this bending mold 26 by this step 36, make overall applicability higher.
In sum, the forming method of the spherical type head of hand-held tool of the present invention and device thereof, make this blank 41 coordinate this chamfer mould 21, extend mould 22, print die 23 according to above-mentioned steps, and this swaging mould 24, to forge this ball-type head 425, not only can effectively reduce equipment and cost of material, reduce process time, can also promote bulk strength.
