Description
本發明係有關於一種手工具成型方法,尤指一種利用沖壓成型及滾軋成型之冷鍛加工方法加工成型者。 The present invention relates to a hand tool forming method, and more particularly to a cold forging processing method using press forming and roll forming.
按,習知生產手工具如板手時,係先裁切出預定長度的圓棒型料條,之後對圓棒型料條加熱至通紅使溫度超過八百度以上之溫度,進行熱鍛使圓棒型料條軟化,接著利用上模與下模對已軟化的圓棒型料條施以加壓鍛打形成一扳手胚料,靜待冷卻後再將扳手胚料表面因鍛打形成之溢料加以沖切,使扳手胚料周邊之廢料得以消除形成一扳手本體,進而再進行熱處理以及表面處理者,俾能完成板手成品者。 According to the conventional production of hand tools such as wrenches, the round bar type strips of predetermined length are first cut, and then the round bar type strips are heated to red to make the temperature exceed the temperature of eight hundred degrees or more, and hot forging is performed. The rod type strip is softened, and then the softened round bar type strip is pressed and forged by the upper mold and the lower mold to form a wrench blank, and the surface of the wrench blank is formed by forging after being cooled. The material is punched, so that the waste around the blank of the wrench can be eliminated to form a wrench body, and then heat treatment and surface treatment are performed, and the finished product can be completed.
詳觀上述習知結構不難發覺其缺點之處,主要原因係歸如下:(一)其習知步驟係必須先將圓棒型料條加溫至八百度以上,且合模加壓鍛打成型後,其扳手胚料仍處於高溫狀態,故須等待使其冷卻,以利於進行後續加工作業,但是等待冷卻的過程相當耗時,影響整個生產進度,造成習知製作方法繁雜、不便,進而增加成品完成之時間,不具經濟效益者。 It is not difficult to find out the shortcomings of the above-mentioned conventional structure. The main reasons are as follows: (1) The conventional steps must first warm the round bar type to more than eight Baidu, and the clamping press forging After forming, the wrench blank is still in a high temperature state, so it has to wait for it to cool, so as to facilitate the subsequent processing, but the process of waiting for cooling is quite time consuming, affecting the entire production schedule, resulting in complicated and inconvenient manufacturing methods. Increase the time to complete the finished product, not economically beneficial.
(二)其經過鍛打的扳手胚料會在周邊產生多餘廢料,這些廢料佔整個圓棒型料條的百分之五十,進而浪費過多的材料,且高溫的扳手胚料降至室溫時會於扳手胚料的外表面產生脫碳層,也就是所謂的瑕疵,此脫碳層必須再以經過人工研磨加工的步驟予以去除,徒增加工成本,導 致原料以及加工成本居高不下,不具經濟效益者。 (2) The forged wrench material will produce excess waste in the periphery, which accounts for 50% of the entire round bar type strip, which wastes too much material, and the high temperature wrench material is lowered to room temperature. When a decarburized layer is formed on the outer surface of the wrench blank, the so-called crucible, the decarburized layer must be removed by manual grinding, which increases the labor cost. The raw materials and processing costs remain high and are not economically viable.
(三)又廢料係環繞於扳手胚料的周邊,形成夾具在夾固上的阻礙,使得扳手胚料無法有效的固定在夾具上以進行去除廢料的作業,故必須以人工方式研磨以去除廢料,不但耗費工時亦浪費了人力成本,且由於廢料的厚度控制不易,經常使得鍛打後的每一個扳手胚料的尺寸公差過大,尺寸精準度不佳,進而使產品不良率過大,形成製程上的一大困擾。 (3) The waste material is wrapped around the periphery of the wrench blank to form a clamp on the clamping, so that the wrench blank cannot be effectively fixed on the fixture for the purpose of removing the waste, so it must be manually ground to remove the waste. Not only does it cost labor to waste labor costs, but also because the thickness control of the scrap is not easy, often the size tolerance of each wrench blank after forging is too large, the dimensional accuracy is not good, and the product defect rate is too large, forming a process A big problem on the.
(一)、按,習知手工具成型步驟係必須先將圓棒型料條加溫至八百度以上,且合模加壓鍛打成型後,其扳手胚料仍處於高溫狀態,故須等待使其冷卻,以利於進行後續加工作業,但是等待冷卻的過程相當耗時,影響整個生產進度,造成習知製作方法繁雜、不便,進而增加成品完成之時間,不具經濟效益者。 (1) According to the conventional hand tool forming step, the round bar type strip must be heated to above 8 Baidu, and after the clamping press forging and forming, the wrench blank is still in a high temperature state, so it is necessary to wait. It is cooled to facilitate subsequent processing operations, but the process of waiting for cooling is quite time consuming, affecting the entire production schedule, resulting in complicated and inconvenient manufacturing methods, thereby increasing the time for completion of the finished product, and not economically beneficial.
(二)、其經過鍛打的扳手胚料會在周邊產生多餘廢料,這些廢料佔整個圓棒型料條的百分之五十,進而浪費過多的材料,且高溫的扳手胚料降至室溫時係會於外表面產生脫碳層,也就是所謂的瑕疵,此脫碳層必須再以經過人工研磨加工的步驟予以去除,徒增加工成本,導致原料以及加工成本居高不下,不具經濟效益者。 (2) The forged wrench material will produce excess waste in the periphery, which accounts for 50% of the entire round bar type strip, which wastes too much material, and the high temperature wrench material is reduced to the chamber. The warm time system will produce a decarburization layer on the outer surface, which is called so-called enamel. This decarburization layer must be removed by the manual grinding process, which increases the labor cost, resulting in high raw materials and processing costs, and no economics. Benefits.
(三)又廢料係環繞於扳手胚料的周邊,形成夾具在夾固上的阻礙,使得扳手胚料無法有效的固定在夾具上以進行去除廢料的作業,故必須以人工方式研磨以去除廢料,不但耗費工時亦浪費了人力成本,且由於廢料的厚度控制不易,經常使得鍛 打後的每一個扳手胚料的尺寸公差過大,尺寸精準度不佳,進而使產品不良率過大,形成製程上的一大困擾,以上此乃為本發明欲解決之技術問題點者。 (3) The waste material is wrapped around the periphery of the wrench blank to form a clamp on the clamping, so that the wrench blank cannot be effectively fixed on the fixture for the purpose of removing the waste, so it must be manually ground to remove the waste. Not only does it cost labor, but also wastes labor costs, and because of the difficulty in controlling the thickness of the scrap, it often makes forging The dimensional tolerance of each of the spanners after punching is too large, and the dimensional accuracy is not good, which in turn causes the product defect rate to be too large, which causes a great trouble in the process. The above is the technical problem to be solved by the present invention.
