Description

用於開口扳手之加工刀具Machining tools for open end wrenches

本創作與開口扳手有關，特別是指一種用於開口扳手之加工刀具。This creation is related to open-end wrenches, especially a machining tool used for open-end wrenches.

開口扳手是十分普及的手工具，在使用時主要利用一端頭部的開口夾制螺帽或螺栓頭，接著對柄部施力，從而讓使用者可以用較為省力的方式鎖緊或鬆放螺帽或螺栓頭。Open-end wrench is a very popular hand tool. When in use, it mainly uses the opening at one end of the head to clamp the nut or bolt head, and then applies force to the handle, so that the user can lock or loosen the screw in a more labor-saving way. cap or bolt head.

就開口扳手的傳統製造方法來說，在經過鍛造完成後的扳手粗胚90會在開口92處保留一連接部94(如圖1所示)，然後先利用沖床將連接部94沖斷後再改到拉床進行加工，藉由拉刀的拉削加工即可將開口92加工至所需要的尺寸。然而，前述製造方法需要操作多種不同的專用加工機，不僅過程較為繁複，在成本方面也會相對提高，因此仍有改善的空間。As far as the traditional manufacturing method of an open-end wrench is concerned, the rough wrench 90 after forging will retain a connecting portion 94 at the opening 92 (as shown in FIG. 1 ), and then the connecting portion 94 is first punched by a punch and then changed. The opening 92 can be processed to the required size by broaching with a broach. However, the aforesaid manufacturing method requires the operation of many different special-purpose processing machines, which is not only complicated in the process, but also relatively increases in cost, so there is still room for improvement.

本創作之主要目的在於提供一種用於開口扳手之加工刀具，其能一次完成開口的加工，以簡化製程和降低成本。The main purpose of this creation is to provide a machining tool for an open-end wrench, which can complete the machining of the opening at one time, so as to simplify the manufacturing process and reduce the cost.

為了達成上述主要目的，本創作之加工刀具包含有一刀頭固定座、一刀頭單元，以及一固定件。該刀頭單元具有一精削刀頭、一粗削刀頭和一沖孔刀頭，該精削刀頭、該粗削刀頭和該沖孔刀頭依尺寸朝遠離該刀頭固定座的方向由大到小排列；該固定件由下而上依序穿過該沖孔刀頭、該粗削刀頭和該精削刀頭，並且以可拆卸的方式設於該刀頭固定座。In order to achieve the above-mentioned main purpose, the processing tool of the present invention includes a cutter head fixing seat, a cutter head unit, and a fixing piece.
