Description

以無屑方式形成螺紋的螺釘
本發明有關無屑成形螺紋形狀螺釘，如上述申請專利範圍第1項之方法。此種螺釘特別適用於用螺絲固定金屬片。
美國4194430專利，如眾所週知，公開一種具有頭之螺紋形狀螺釘，遠離頭之一方成為尖端，尖端或(似)點尖端。相當大之螺釘體上具有螺紋，自螺釘體末端至尖圓錐形部分，螺紋高度，越接近螺釘之尖端越低。
此種螺紋形成的螺釘之缺點是，僅能在高硬度材料中先前鑽好孔內形成螺紋，先前未鑽孔之金屬片，僅適用於極薄金屬片，如製造汽車用者。用螺絲固定多片疊放堆高之金屬片，此種螺釘並不適合。
美國5597357專利，如眾所週知者，為一種自動鑽孔之螺釘。遠離端有一鑽尖端。此種自鑽之螺釘可穿透2公厘以上厚度之金屬片。
此種自動鑽孔螺釘有缺點，制定穩定切屑程序，必須節省腐蝕所引生之龐大費用。而且使用人，在整個鑽孔期間必然集聚相當緊壓力。而且切削必然喪失材料，致而無法發揮支撐緊壓夾具之作用。
本發明之任務為避免上述缺點及供應螺紋形狀之螺釘，無屑成形或堆高至少兩片金屬薄片上下重疊總厚度為 至少2公厘。
螺釘之供應，夾緊或堆積至少兩塊疊放一起之金屬薄片總厚度至少2公厘可貫穿。
此等任務可透過申請專利範範第1項所描述之手段達成。因此尖端之直徑為0.25至0.35公厘，與緊接著之尖圓錐形部分之尖端夾角為20°至30°。隨頭遷移之螺紋開端與尖端相距0至0.3公厘。透過本發明之頂點幾何學，螺紋形狀螺釘上金屬片與堆高之金屬片在尖圓錐形部分有一銳角20°至30°。頭部尚有螺紋開端(23)，與尖端距離0至3公厘。透過本發明之頂點幾何學，可用螺紋形狀螺釘無屑成形貫穿3.1公厘厚(薄鋼片)金屬薄片及金屬薄片堆。較不硬之金屬薄片，如鋼薄片，貫穿厚度則相應較高。
圓筒形部分至尖圓錐形部分之螺紋，其高度，朝尖端方向逐步低減。藉此措施螺釘可獲得優良之旋入性能，方能於第一次貫穿後，螺釘尚能自行旋入材料或地下設施。
另一優點，當螺紋高度在尖圓錐形部分(依公式：H=((tan(α/2)+FB )* X+.2mm)-RK
確定時，其中FB 為一值在0.04至0.25間之常數，RK 為(螺釘)體與尖端間之距離X處之半徑。因此而可獲得螺釘旋入螺釘最佳性能。
另一優點為螺釘體圓筒形部分(25)有一3.0至6.3公厘之直徑，因此貫穿性能與必要之螺釘間之旋緊密切配合。
圖示者為本發明之具體實施例。
第一圖為本發明無屑成形螺紋形狀螺釘之縱剖面圖。
第二圖示第一圖標記II所示螺釘之細節。
第一圖所示之無屑方式形成鑽孔及螺紋的螺釘10，其具有螺釘體11，該螺釘體係承載著螺紋15且在其中一端處具有一尖端及在另一相對立的端處具有一頭14。螺釘中心線確定螺釘10之軸線。頭14有一螺釘工具17。尖圓錐形部分21自錐形螺釘中心端頭13往頭14方向延伸。此尖圓錐形部分21自尖端13與圓筒部分25連接。直徑DS 約3.0-6.3公厘。
尤其第二圖顯示尖圓錐形部分21涉及螺紋基底22尖端夾角α，其係在20°至30°之間。尖端13尚有一0.25~0.35公厘之另一直徑Dt 。
螺紋15有一螺紋高度H，其在圓筒形部分25基本上保持恆定，而於尖圓錐形部分21，朝錐形端點方向螺紋高度遞減。螺紋開端23位於距離Lt 處，距尖端13為0至0.3公厘。螺紋高度H在尖圓錐形部分21透過函數定義：H=((tan(α/2)+FB )* X+.2mm)-RK
其中FB 為值在0.04至0.25間之常數，RK 為尖端13與螺釘體距離X(中心線A至螺紋基底22之半徑X)。
減低摩擦至少在螺釘體11區域螺釘尚可用減低摩擦塗料如蠟或切削油。
優點是螺紋經過圓筒形部分至尖圓錐形部分，其中螺紋高度，在其尖圓錐形部分，越接近尖頂越低。藉此措施，可獲得良好旋入螺釘性能，所以螺釘藉旋轉於第一次貫穿 後，即自動旋進材料及地下設施。
