The blank 28 is transferred to the space between the fixed die holder 66 and the movable die holder 68. 71 (see Figure 2). Moreover, as shown in FIG. 3, when the camshaft 54 moves along the horizontal direction, the sliding block 52 is driven to descend, so that the gear 56 is rotated by 180 degrees, thereby driving the fixed mold base 66 and the The screw blank 28 between the movable die holders 68 is turned such that the second end 31 of the screw blank 28 faces the clamping device 18; then, as shown in Figs. 4 and 5, the clamping device 18 is raised and held. The second end 31 of the screw blank 28 and reciprocating between the steering device 16 and the second mold unit 14 can sequentially transfer the plurality of screw blanks 28 from the steering device 16 to the second mold unit 14 Each processing position is to progressively complete the processing of the second end 31 of the screw blank 28, and the screws that complete the processing of the second end 31 are transferred to the collection zone 50 for collection (see Figure 6).
在圖4中顯示當該滑動塊52向下移動時，位在該滑動塊52下方的彈簧72會被壓縮，因而，當該凸輪軸54沿著該水平方向移動而復位時，該彈簧72的彈力會使該滑動塊52向上移動而復位(見圖5)。在圖4中並顯示當該夾鉗裝置18上升夾持螺絲胚料28時，該上模座40相對該下模座38向上移動，使得螺絲胚料28可脫離該槽孔42、44。在圖5中顯示當該夾鉗裝置18的滑動座76向右移動至下一個工位置時，該滑動塊52復位且帶動該齒輪56轉動180度而復位。 It is shown in FIG. 4 that when the slider 52 is moved downward, the spring 72 located below the slider 52 is compressed, and thus, when the camshaft 54 is moved in the horizontal direction to be reset, the spring 72 is The spring force causes the slider 52 to move up and reset (see Figure 5). In FIG. 4, it is shown that when the clamping device 18 is raised to hold the screw blank 28, the upper die holder 40 is moved upward relative to the lower die holder 38 so that the screw blank 28 can be detached from the slots 42, 44. It is shown in Fig. 5 that when the sliding seat 76 of the clamp device 18 is moved to the right to the next working position, the sliding block 52 is reset and the gear 56 is rotated 180 degrees to be reset.
依據本發明構成的螺絲成型裝置10不僅具有簡單的結構，且該螺絲成型裝置10可連續地對螺絲胚料28的兩端部進行加工，使得特殊螺絲的成型可在同一機台上完成，因而，可有效縮減特殊螺絲的加工速度且降低加工成本。 The screw forming apparatus 10 constructed in accordance with the present invention not only has a simple structure, but the screw forming apparatus 10 can continuously process both ends of the screw blank 28 so that the molding of the special screw can be completed on the same machine. It can effectively reduce the processing speed of special screws and reduce the processing cost.
前述是就本發明一特定實施例做描述，而依本發明的設計特徵將可做多種變化或修改是可了解的。故對於熟悉此項技藝人士可作之明顯替換與修改，仍將併入於本發明所主張的專利範圍內。 The foregoing is a description of a particular embodiment of the invention, and various modifications and Therefore, obvious substitutions and modifications to those skilled in the art will still be incorporated in the scope of the claimed invention.
