New Description: [New Technology Field] This creation is a kind of drill screw mold. It has made a structural improvement design on the mold surface of the tail-drilling feature. The surface of the parallel plane is changed to the front low-height slope, so that the tail-drilling feature can be easily manufactured when manufacturing the self-drilling screw, and the residual waste is easily detached when the tooth is removed. '〇秦【前技术】 # The drill tail feature of the conventional drill-tail screw is made up of a set of two drilling screw forming molds (as shown in Figure 1). When used, the mold is locked and fixed on the drill. In the mold base of the tail screw forming machine, after the correction to the critical size, the self-drilling screw forming machine closes the two molds face to face with a punch-like action principle. At this time, the wire placed between the two molds is Extrusion deformation (shown in Figures 1, 2, and 3) becomes the feature of the drill tail on the drill tail screw (as shown in Figure 4), and the excess wire becomes waste. Next, the process of cavities will remove excess scraps and make the lines of the teeth. However, the conventional technique is convenient for making the mold surface is parallel to the end surface of the mold, and the mold surface is often made very low. Avoid mold damage caused by too much force, which will cause disputes between the mold supplier and the screw manufacturer. However, the low mold surface will cause the residual waste to be easily separated from the drill tail feature. Even in the case of tooth decay, the residual waste can easily be wound onto the chip sipe on the drill tail feature to cause a defective product of the drill screw. [New content] Therefore, the purpose of this creation is to make the die face of the drill tail function on the mold, design it with computer, and make a careful calculation, and then make an optimized front, low and high slope to make When making the tail tail feature, the residual waste is easily detached. 5 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。
如圖六所示，本創作是以電腦設計，並且審慎計算，而做出一個最佳化的， 前低後高的斜面(8)。製造鑽尾(5)特徵時，兩顆鑽尾模具(1)緊密配合，夹在 中間的線材(2)會被擠壓變形成鑽尾(5)特徵及殘廢料(4)兩個部份。由於模面 是一個前低後高的斜面(8)，在擠壓碰撞時，前面低，空間大，製造鑽尾特徵 時模具不易損傷；後面高，空間小，殘廢料(4)會被擠扁，搓牙的時候殘廢料 (4)很容易脫離。 【圖式簡單說明】 第一圖是習知鑽尾螺絲模具作動原理(一）； 第二圖是習知鑽尾螺絲模具作動原理(二）； 第三圖是習知鑽尾螺絲模具作動原理(三）； 第四圖是線材所製造出來的鑽尾特徵與殘廢料; 第五圖是傳統模具上製造鑽尾特徵的模面； 第六圖是改良模具上製造鑽尾特徵的模面； 第七圖是兩種殘廢料之比較； 【圖式之主要元件代表符號簡單說明】 1.鑽尾模具 2·線材 6 M340872 3. 動作方向 4. 殘廢料 5. 鑽尾 6. 模具上製造鑽尾功能的模面 7. 終止面 8. 前低後高的斜面 9. 鑽尾特徵上的排屑溝As shown in Figure 6, the creation is based on computer design and careful calculation, and an optimized, low front and high rear bevel (8). When manufacturing the tail (5) feature, the two drill tail molds (1) are closely matched, and the wire (2) sandwiched between them will be squeezed to form the tail (5) feature and the residual waste (4). . Since the die face is a front low and high profile bevel (8), the front face is low and the space is large during the extrusion collision. The mold is not easily damaged when the tail feature is manufactured; the rear is high, the space is small, and the residual waste (4) is squeezed. When the fangs are damaged, the scraps (4) are easily separated.
