M408429 ' 五、新型說明： 【新型所屬之技術領域】 本新型是有關於一種螺桿成型加工機，該螺桿成型加 Λ 工機具有成型出螺桿之螺紋部以及對螺紋部尖端修除銳利 ' 毛邊之功能。 【先前技術】 目前市面上現有的滚牙機皆為單次加工的機械，只能 φ 對工件加工成型出螺桿的螺牙段而已，由於螺桿在成型出 螺牙之後，螺牙的尾端呈現銳利的尖牙，為了防止刮傷手 部等意外，通常會將已成型螺牙段的螺桿經過修毛邊的機 具作再次加工，方符合使用需求。 如上可知，由於現有的滾牙機只有單次加工的功能， 已成型螺牙段螺桿必須自滚牙機上拆下來，再拿到修毛邊 的機具經由切削導角的作業，才能完成螺桿的成品，而且 φ 切削導角的作業往往由人工操作。 所以，以往螺桿的加工方式增加了拆卸的步驟，不但 增加拆除工件與校正中心之工時，相對的也提高螺桿之製 造成本。 在現有的滚牙技術上，由於螺桿之螺紋加工作業並不 困難，因此如果能夠達到一機一次完成加工作業，將可省 去不少的工時與成本。 【新型内容】 3 M408429 中，該升降單元包含有一固定座、一升降螺桿、一滑座及 一動力單元。該固定座係設在該主軸單元上方。該升降螺 桿，係設於該固定座中。該滑座，係可上下移動地滑設於 該固定座之前側，且該滑座具有一與該升降螺桿相螺接的 螺接件，該導角加工單元則係設於該滑座上。該動力單元， 用以驅動該升降螺桿轉動，以帶動該滑座上下位移。M408429 ' V. New description: [New technical field] The present invention relates to a screw forming machine which has a threaded portion for forming a screw and a sharp edge for the tip of the thread. Features. [Prior Art] At present, the existing rolling machines on the market are all single-machined machines, and only the screw segments of the screw can be formed by machining the workpiece. Since the screw is formed after the screw is formed, the end of the thread is presented. Sharp fangs, in order to prevent accidents such as scratching the hand, usually the screw of the formed screw segment is reworked by the edging machine to meet the needs of use. As can be seen from the above, since the existing rolling machine has only a single processing function, the formed screw segment screw must be removed from the rolling machine, and then the trimming machine can be finished by cutting the lead angle to complete the screw finished product. And the work of cutting the lead angle by φ is often performed manually. Therefore, in the past, the processing method of the screw has increased the step of disassembly, which not only increases the man-hours for removing the workpiece and the calibration center, but also increases the manufacturing cost of the screw. In the existing rolling technology, since the screw threading operation is not difficult, if a machine can be completed in one operation, a lot of man-hours and costs can be saved.

The cutter 4 3 rotates. Referring to Figures 8 and 11, after the thread forming tool 43 of the spindle unit 4 has finished the machining of the thread portion of the workpiece 1 ,, the thread forming tool 43 is axially oriented in the x-axis direction. Sliding out of the processing area, and then the angle forming unit 8 is displaced downward by the lifting unit 7〇 to bring the tool 82 close to the workpiece 1 and machining the lead portion of the workpiece 1〇〇 1 2◦ to remove the 1 piece ◦Q thread part! Sharp corners of 10 (see Figure 9). As mentioned above, compared with the conventional rolling machine, the screw can only be used as a single function to machine the screw, so that the burr processing of the screw must be changed to another b, and the machine is finished with the burr, resulting in an increase in Μ(4). problem.
