Each of the cutting faces 141 has a cutting edge end 142 adjacent to the first end face ill. However, although the whole mold i can punch the cylindrical screw head 101 into a polygonal shape, in the process of punching, in order to avoid the rapid wear of the hard cutting edge 5 M305725 142, the conventional die 1 is known. Usually steel is used for the potential difference. Although the selection of this = can slow down the speed of cutting...42 wear: but: ~ Xian 1 1 · Made with Saki, its material cost is high, while 7 blades: 2 2 use - segment time damage When, though, the whole mold i is the other. The niche is still very complete, but it still needs to be replaced, /, required, Μ Μ — the entire mold is not necessary. In addition, in the process of punching, since the entire die cutting plane 141 is parallel to the central axis, χ _ n , c 夕 形 angled head 102 2:: after molding the cavity 13 'the various sections of the screw head 102 will And hard. Fitting this will also cause difficulty in demoulding. [New content] The purpose of the present invention is to provide a full-head mold for screwing the screw head which is easy to be used for 3L and demoulding. The die-cutting die is used to punch a cylindrical screw head of the screw blank, and can be punched in a punching direction, including a two-base 'and a detachable mount on the base The upper mold base, the mold base: is made of a carbonized crane material, and includes a cutting torus disposed along the punching direction and defining the forming core pocket, the cutting ring surface having a plurality of adjacent sides and a circumference The inclined surface of the axis, each inclined surface has a circular cutter end adjacent to the screw blank and a large end which is spaced from the end of the circular cutter, and the inclined surface is cut by an arc The blade end gradually moves away from the central axis toward the enlarged end. . A separate design of the base and the mold base can be used again when the cutting edge of the arc of the mold base is bad. By using the mold base separately, it can be used again, and the cutting ring with 6 M305725 has a cutting function. The surface is placed on the mold base, so the new type can be extended to the specific part of the (four) seat to extend the service life of the whole mold to further reduce the cost of use. In addition, due to the arc-arcing phase and the inclined surface of the arc cutting end of the present invention, the die holder can be more easily cut into the screw head, and the cutting faces of the screw head and the inclined faces of the die base are avoided after cutting. Closely attached, this new design also has the advantages of easy cutting and easy demoulding. [Embodiment] The above-mentioned and other technical contents of the present invention will be presented in the following detailed description with reference to the drawings and the preferred embodiments. Referring to Figures 3, 4 and 5, one of the preferred embodiments of the present invention is a cylindrical screw head 22 of a screw blank 21, which is a knife cutter. Forming a polygonal screw head 23' The polygonal screw head 23 has a polygonal screw end face, and a plurality of screw head faces 232 that meet each other and surround a center face. However, in actual machining, the tapping of the screw head of the screw head 23 is not limited to the six dimensions of the figure, that is, the number can be three, *, and the like. The whole mold of the present invention can be moved closer to the screw blank 21 along a punching and cutting direction, including a metal base and a mold base which is detachably combined with the base 3. 4. The base 1 h, the mountain 13 includes a slanting ring disposed toward the screw blank 21 and surrounding the central axis 20, a gentleman's cymbal 31, a first space spaced from the inclined annular surface 31 and perpendicular to the central axis 2〇 The old straight face 32, and an Anon torus around the central axis 20 and defining a mounting groove 33. Upper 7 M305725 "The grooving 33 has an enlarged state adjacent to the screw blank 21, and = a narrowing portion away from the screw blank 21", and the mounting 34 has an installation corresponding to the enlarged portion 331 The face portion 341 and the l:t abutting portion 342 between the enlarged portion 331 and the reduced portion 332 and disposed in the radial direction 〇
本實施例之模座4係由碳化鶴材料製成，部份區域並 ―!熱處理’上述模座4包括:一個朝向螺絲胚品j之第 严：面41、—個與第-端面41間隔並靠抵在基座3之抵靠 :邛342上的第二端面42、一個圍繞該中心軸線，並界定 2成型杈穴43的裁切環面44 ’以及—個圍繞該中心軸線 並與基座3之安裝面部341貼合的外環面45。在本實施 例中，該成型模穴43的截面係與多角形螺頭23配合，而 4裁切環面44則是具有6個圍繞該中心軸、線20的斜面部 每個斜面』441都具有一個鄰近第一端面41之圓弧 切刀端442，以及-個與第二端面42接連之擴大端⑷， 亦即’該等斜面部441係由鄰近第一端面Μ的一端逐漸地 在第二端面42及徑向外端傾斜擴大，於該第—端面41上 則具有6個㈣等斜面部441為基準往外並往第：端面42 方向傾斜的斜切面部411。 多閱3 6本新型之整頭模具在使用時，該模座4是 可拆離地安裝在基座3之安裝槽33内，安裝後該模座4之 弟二端面42的徑向内端略為突出於縮小部332,而該模座 4之第一端面41的斜度，大致與基座3之斜環面31接續。 當整頭模具相對於具有螺絲胚品2ι之聽形螺頭Μ移近 8 M305725 並進订冲切時，该权座4之該等斜面部⑷上的圓弧切刀 端442會往圓柱形螺頭22沖切，並且將圓柱形螺頭22裁 刀成夕角$螺_ 23。而在裁切的瞬間，經過熱處理之斜面 部441上的圓弧切刀端他由於具有較佳的結構強度，因 本新型在作沖切加工時，不僅具有較長的使用壽命， A座4使用一段時間而有毀損時，只要更換該模座*即 ^繼績使用，故本新型該整頭模具的設計可以節省使用成The mold base 4 of the present embodiment is made of a carbonized crane material, and a part of the area is heat-treated. The mold base 4 includes: a first portion facing the screw blank j: a surface 41, which is spaced from the first end surface 41 And abutting against the base 3: a second end surface 42 on the crucible 342, a cutting annulus 44' surrounding the central axis and defining 2 forming cavities 43, and a surrounding center axis and base The outer ring surface 45 to which the mounting surface 341 of the seat 3 is attached. In the present embodiment, the section of the molding cavity 43 is matched with the polygonal screw head 23, and the 4-cut toroidal surface 44 is a beveled surface having six inclined faces around the central axis and the line 20 441 Having a circular cutter end 442 adjacent to the first end surface 41, and an enlarged end (4) connected to the second end surface 42, that is, the inclined surface 441 is gradually adjacent to the end of the first end surface The second end surface 42 and the radially outer end are inclined and enlarged, and the first end surface 41 has six (four) equal inclined surface portions 441 as a reference obliquely facing surface 411 which is inclined outward in the direction of the end surface 42. When the whole mold of the new type is used, the mold base 4 is detachably mounted in the mounting groove 33 of the base 3, and the radially inner end of the second end face 42 of the mold base 4 is mounted after installation. Slightly protruding from the reduced portion 332, the slope of the first end surface 41 of the die holder 4 is substantially continuous with the inclined ring surface 31 of the base 3. When the whole mold is moved closer to 8 M305725 with respect to the accommodating screw head having the screw blank 2, and the punching is performed, the circular cutter end 442 on the inclined surface portion (4) of the weight 4 will be snailed into the cylindrical snail. The head 22 is die cut and the cylindrical screw head 22 is cut into an angling angle of $ _ 23 . At the moment of cutting, the circular arc cutter end on the heat-treated inclined surface portion 441 has better structural strength, and the present invention not only has a long service life when being subjected to punching processing, A seat 4 When it is used for a period of time and there is damage, the design of the whole mold can be saved by simply replacing the mold base*.
此外’本新型在該等斜面部441鄰近螺絲胚品21的一 端所形成之圓弧切刀端442，可以讓模座4之裁切環面44 更易於沖切入螺絲胚品21之圓柱形螺頭以内，而在沖切 之後，由於多角形螺頭23上的各個螺頭切面232是被圓弧 切刀端州所切成，而該等圓弧切刀端州離中心轴線2〇 =離又是該裁切環面44上最小的部份，因此，在裁切後 。亥夕角形螺頭23之各個螺頭切自232不會和裁切環面糾 上的各個斜面部441緊褒的目上入 X， r 、、 蒗么的貼合，故本新型該項設計也可 以達到沖切容易以及脫模方便等功效。 ▲ f隹以上所述者，僅為本新型之較佳實施例而已，當不 能以此限定本新型實施之範圍，即大凡依本新型申^利 範圍及說明内容所作之簡單的等效變化與修飾，皆:屬本 新型專利涵蓋之範圍内。 【圖式簡單說明】 同時顯示該整頭 圖1是一種習知整頭模具的立體圖 模具與一螺絲胚品的對應關係； 9 M305725 圖2是該習知整頭模具的一使用剖視圖； 圖3是本新型整頭模具之一較佳實施例的立體分解圖 ，同時顯示該整頭模具與一螺絲胚品的對應關係； 圖4是該較佳實施例之一剖視分解圖； 圖5是該較佳實施例之一局部放大圖，單獨顯示該整 頭模具之一模座的局部構造；及 圖6是該較佳實施例之一組合剖視圖。In addition, the arc-shaped cutter end 442 formed at one end of the inclined surface portion 441 adjacent to the screw blank 21 can make the cutting ring surface 44 of the mold base 4 more easily punched into the cylindrical screw of the screw blank 21 Within the head, after the punching, since each of the screw heads 232 on the polygonal screw head 23 is cut by the arc cutter end state, the arc cutter ends from the central axis 2〇= It is again the smallest part of the cut torus 44 and, therefore, after cutting.
