Description

扳手工具胚料的成型方法Method for forming blank of wrench tool

本發明是有關於一種成型方法,特別是指一種用於製成扳手工具的胚料之成型方法。The invention relates to a forming method, in particular to a forming method for making blanks of wrench tools.

扳手工具是十分普及的手工具之一,使用時是先以扳手工具的頭部來夾制螺帽,接著對扳手工具的手柄部分施力,從而讓使用者可省力地擰緊或扭鬆螺帽及螺桿。而扳手工具的頭部可為概呈U字形的開口,也可為封閉式且具有內鋸齒的封閉式開孔,甚至是可讓使用者在進行擰緊或扭鬆動作時,不需將頭部由螺帽或螺桿移開的棘輪結構。由於扳手工具具有兩個相反端,因此常會在扳手工具兩端搭配不同類型的頭部,以增加功能性。The wrench tool is one of the very popular hand tools. When using it, first use the head of the wrench tool to clamp the nut, and then apply force to the handle part of the wrench tool, so that the user can easily tighten or loosen the nut. And screw. The head of the wrench tool can be a generally U-shaped opening, or it can be a closed type with a closed hole with internal serrations. It can even allow the user to tighten the head without loosening the head. A ratchet structure removed by a nut or screw. Because the wrench tool has two opposite ends, different types of heads are often used at both ends of the wrench tool to increase functionality.

參閱圖1,上述的扳手工具製作時,是先將未加工的金屬製的原料11成型為一胚料12,再透過切削、打磨,或精整等後處理程序,以將胚料12製成扳手工具。而一般胚料12的成型方法是包含一備料步驟、一加熱步驟、一沖壓步驟、一冷卻步驟,及一除料步驟。在該備料步驟中,是先取一金屬圓桿作為原料11並裁切至適當長度。在該加熱步驟中,是以加熱裝置對該原料11施以固定高溫進行加熱軟化處理。在該沖壓步驟中,是以模具對高溫軟化後的原料11進行沖壓,以將圓柱狀的原料11成型為扁平狀態。在該冷卻步驟中,是等待該原料11冷卻以確保定型。在該除料步驟中,是以除料機根據所需的輪廓進行廢料切除作業,從而製得所需的扳手工具胚料12。Referring to FIG. 1, when the aforementioned wrench tool is manufactured, the raw metal material 11 is first formed into a blank 12, and then the blank 12 is made through a post-processing procedure such as cutting, grinding, or finishing.

In this preparation step, a metal round rod is first taken as the raw material 11 and cut to an appropriate length. In this heating step, the raw material 11 is subjected to a heating and softening treatment at a fixed high temperature by a heating device. In this pressing step, the raw material 11 that has been softened at a high temperature is punched with a mold to form the cylindrical raw material 11 into a flat state. In this cooling step, the raw material 11 is waited for cooling to ensure the setting. In this removal step, the waste removal operation is performed by the removal machine according to the required contour, thereby obtaining the required wrench tool blank 12.

然而前述的胚料12成型方法不但需要使用加熱裝置對原料進行加熱軟化,還需將該原料11靜置一段時間以進行冷卻定型,工序繁瑣且須耗費大量電力及工時。此外,該除料步驟是以切削等方式去除多餘的料件,因此會產生廢料而造成成本的增加及資源的浪費。However, the aforementioned method for forming the blank 12 not only requires heating and softening the raw material by using a heating device, but also requires the raw material 11 to stand for a period of time for cooling and setting. In addition, the material removal step is to remove excess materials by cutting or the like, so waste will be generated, which will increase cost and waste resources.

因此,本發明之目的,即在提供一種不需經加熱、冷卻,及除料等工序的扳手工具胚料的成型方法。Therefore, an object of the present invention is to provide a method for forming a blank of a wrench tool without the steps of heating, cooling, and removing materials.
