參閱圖1、圖2,習知扳手工具之冷鍛製造方法1,其包含有一備料步驟11,一頭部區成型步驟12,一沖壓成型步驟13及一除料成型步驟14;其中,在該備料步驟11備具有一圓桿狀之金屬胚料a;另,該頭部區成型步驟12即針對該金屬胚a之二端分別冷鍛沖壓成型出一圓頭a1態樣;至於,該沖壓步驟13即利用一沖床設備(圖中未示)針對前述步驟所成型之該二圓頭a1予以沖壓,使得具有該圓頭a1態樣之該金屬胚料a被沖壓呈現出扁平狀之該扳手工具2的握把與鎖合部外觀;最後,於該除料步驟14再另備具一沖床(圖中未示)並再針對所成型出該扳手工具2之握把與鎖合部外觀周緣處之多餘材料進行除料,使得該扳手工具21得以顯現出具體態樣,如此即完成該扳手工具2的成型。Referring to FIG. 1 and FIG. 2, a cold forging manufacturing method 1 of a conventional wrench tool includes a preparation step 11, a head region forming step 12, a press forming step 13 and a strip forming step 14; The preparation step 11 is provided with a round bar-shaped metal blank a; in addition, the head region forming step 12 is cold forged and stamped to form a round head a1 shape for the two ends of the metal blank a; thus, the punching step 13 That is, the two round heads a1 formed by the foregoing steps are punched by a punching device (not shown), so that the metal blank a having the round head a1 is stamped to exhibit a flat shape of the wrench tool 2 The grip and the appearance of the lock portion; finally, in the stripping step 14, a punch (not shown) is further provided and the grip and the periphery of the lock portion are formed for the wrench tool 2 Excess material is removed, so that the wrench tool 21 can be visualized, thus completing the forming of the wrench tool 2.
惟,實際操作後發現,鑒於習知扳手工具2在成型過程中,皆是使用各種不同驅動力的沖床來進各階段的沖壓作業,即如為初步圓頭a1的冷鍛成形、握把與鎖合槽的沖壓成型,為此才能有效具體成型出該扳手工具2整體態樣,故所具備之該等沖床機具設備的驅動力需比一般機具要高上許多,這樣才能具有足夠的驅動力來進行金屬的冷鍛沖壓行程,更會因為所成型之各部位所使用的設備各有所不同,且長期在相對要承受過大的衝擊力道,更會造成機具設体使用的耗損,即在機具設備所需花費成本便相對的提高,且更因在該扳手工具2於各階段的成型過程中,必需透過不同驅動力之機具與機具間的轉換,才能完成該扳手工具2外觀的成型作業,使得在製程作業上更會造成加工時間的冗長,致使加工效率不佳,而導致製造成本的增加與問題產生,實不符經濟效益有待改進。However, after the actual operation, it is found that, in view of the conventional wrench tool 2, all kinds of punching machines with different driving forces are used for the punching operation in various stages, that is, the cold forging forming of the preliminary round head a1, the grip and the The stamping forming of the locking groove can effectively form the overall shape of the wrench tool 2, so that the driving force of the punching machine equipment is much higher than that of the general machine, so that sufficient driving force can be obtained. In order to carry out the cold forging and stamping stroke of metal, the equipment used in each part to be formed may be different, and the impact force on the machine body may be excessively affected for a long time, which may cause the wear of the machine body, that is, in the machine tool. The cost of the equipment is relatively increased, and the molding work of the wrench tool 2 can be completed by the conversion between the tools and the implements of the different driving forces during the molding process of the wrench tool 2 at various stages.

參閱圖3至圖6,進行製程時,先備妥之具有圓狀線材之金屬胚料b,並依所欲製成之扳手工具7尺寸大小,將該金屬胚料b予以分段剪切,同將並再驅動該加熱器4進行高溫預熱,以使該加熱器4之溫度達到預設的高溫後,便可將該等金屬胚料b一一經由該加熱器4進行加熱,以使該等金屬胚料b經由高溫加熱作用後呈現軟化態樣,如此利用該加熱器4產生之高溫加熱效果,不但可使該金屬胚料b之加工延展性得以提昇外,且更有利於後續各步驟所進行的製程工時能大幅有效地縮短,同時在該金屬胚料b本體上仍具有高溫狀態下可快速成型出所需之型態,是以,當完成該金屬胚料b之加熱作業後,便可接續進行該金屬胚料b之整體塑型作業,這時將該金屬胚料b置放該模具52上,再利用與該模具52對應之該推移件53頂掣於該金屬胚料b上,即可作動該推移件53於該模具52上的移動,促使該金屬胚料b在該推移件53的帶動下,順沿該模具52上之形態進行移動,以使該金屬胚料b在本身之高溫與受到推移雙重作動效應下,即在受推移作動中開始逐漸產生塑性變形作用,順由該模具52上之輪廓形成出具有握持區b2、以及形成於該握區b2兩端之的頭部區b1,同時經塑型而成之該等頭部區b1之外徑d1大於該握持區b2之外徑d2,而後再趁該金屬胚料b上仍具有溫度之時,得以再利用該衝壓機6先行針對該握持區b2,以使該握持區b2經沖壓後而呈現出扁平狀,而後再分別通過該沖壓機6之沖壓模具(圖中未示)來對針對該等頭部區b1產生出衝擊力,以使該等頭部區b1之金屬組織受到衝擊力的推擠態樣遂其成型出鎖合部(槽、孔)形態呈現,如此形成一扳手7,因此利用該金屬胚料b仍具以溫度的狀況下來進行沖壓成型作業,其不會有沖壓過度之裂痕產生,而且廢料少,同時所需成型尺寸、形狀亦在控制範圍中,如此更能使良率有效大幅提升,故,在沖壓作業上,利用該金屬胚料b因加熱、塑性變形後仍殘留有溫度狀況下進行該握持區b2與該等頭部區b1沖壓成型,使得沖壓作業可快速、穩定成型,有利生產成本降低;因此,藉由高溫加熱、調整塑型及快速沖壓成型等一貫化的連續製程進行,不但可減化加工流程與加工機具的使用,減少廢料產生與機具的耗損,有效提升加工效率,達到快速成型出該扳手工具7整體型態,更可大幅降低機械加工成本支出,有效提升扳手工具7成品之成型效率。Referring to FIG. 3 to FIG. 6 , when the process is performed, the metal blank b having a round wire is prepared, and the metal blank b is segmented and cut according to the size of the wrench tool 7 which is prepared. And heating and heating the heater 4 to perform high-temperature preheating, so that the temperature of the heater 4 reaches a preset high temperature, the metal billets b can be heated one by one through the heater 4, so that The metal billet b exhibits a softening state after being heated by high temperature, so that the high-temperature heating effect produced by the heater 4 can not only improve the processing ductility of the metal billet b, but also facilitate subsequent operations. The process time of the process can be shortened substantially effectively, and at the same time, the desired shape can be rapidly formed in the high temperature state of the metal billet b body, so that when the metal billet b is heated, After that, the overall molding work of the metal blank b can be continued. At this time, the metal blank b is placed on the mold 52, and the pushing member 53 corresponding to the mold 52 is used to top the metal blank. b, the pusher 53 can be actuated on the mold 52 Moving, causing the metal billet b to move along the mold 52 under the driving of the pushing member 53, so that the metal billet b is subjected to the double action effect of the high temperature and the shifting effect of the metal billet b. The plastic deformation is gradually started in the shifting operation, and the contour of the mold 52 is formed to form the head region b1 having the holding portion b2 and the both ends of the grip portion b2, and is molded. When the outer diameter d1 of the head region b1 is greater than the outer diameter d2 of the holding region b2, and then the metal billet b still has a temperature, the punching machine 6 can be reused for the holding region b2. So that the holding area b2 is flattened after being punched, and then by the punching die (not shown) of the punching machine 6, respectively, an impact force is generated for the head regions b1, so that the The metal structure of the head region b1 is subjected to the pushing state of the impact force, and the shape of the locking portion (groove, hole) is formed, so that a wrench 7 is formed, so that the metal billet b is still in a temperature state. Down the stamping operation, it will not produce excessive cracking, Moreover, the amount of waste is small, and the required molding size and shape are also in the control range, so that the yield can be effectively increased greatly. Therefore, in the stamping operation, the metal billet b is still left after being heated and plastically deformed. Under the condition, the holding area b2 and the head area b1 are press-formed, so that the stamping operation can be formed quickly and stably, which is advantageous for the production cost reduction; therefore, the high-temperature heating, the adjustment molding, the rapid press forming, and the like are consistent. The continuous process can not only reduce the processing flow and the use of processing tools, reduce the waste generation and machine wear, effectively improve the processing efficiency, and achieve the rapid formation of the overall shape of the wrench tool 7, and can greatly reduce the cost of machining. Effectively improve the forming efficiency of the finished wrench tool 7.

2.接續前述,在該塑型步驟33與沖壓成型步驟34中,係先分別針對經高溫加熱後之該金屬胚料b進行塑性變形作業,故在此製程作業中,係有別於習知需透過各種不同驅動力之機具與機具間的轉換進行,才能得所需之成品型態,因此通過高溫軟化效果作用下不但可快速塑型出所需之握持區b2與該等頭部區b1的形成,而不會有廢料產生外,同時更在接續該沖壓成型步驟34中,利用該沖壓機6可分多次壓來進行,因而能完全使該握持區b2呈一扁平狀,而該等頭部區b1成型出鎖合部(槽、孔)形態呈現,如此不但可減化使用之加工機具的使用,廢料大幅減少外,更能使沖壓作業可快速、穩定成型,有利製程生產成本的降低。2. Following the above, in the molding step 33 and the press forming step 34, the metal blank b after the high temperature heating is separately subjected to plastic deformation operation, so that the process is different from the conventional one. It is necessary to carry out the conversion between the implements and the implements of various driving forces in order to obtain the desired finished product type. Therefore, not only the required holding area b2 but also the head area can be quickly molded by the high temperature softening effect. The formation of b1, without the generation of waste, and at the same time in the subsequent press forming step 34, the punching machine 6 can be used for multiple times of pressing, so that the holding area b2 can be completely flattened. The head regions b1 are formed into a form of a locking portion (groove, hole), which not only reduces the use of the processing tools used, but also greatly reduces the amount of waste, and enables the stamping operation to be formed quickly and stably, which is advantageous for the process. Reduced production costs.
