Description
本發明是關於一種製造方法,特別是指一種充分利用鏈條製造過程產生的廢料來生產鏈條之零件的製造方法。The present invention relates to a manufacturing method, and more particularly to a method of manufacturing a part that utilizes waste generated by a chain manufacturing process to produce a chain.
鏈條由於具有可撓性及較佳的機械強度,因此,經常被運用在機械領域中,以作為動力傳遞的構件,隨著安裝機械體動力大小的不同,一般鏈條的規格也很多,例如用於大型機械的動力傳遞的鏈條尺寸較大、結構較強,而一般自行車使用的鏈條的尺寸較小。但無論何種尺寸的鏈條,其通常包含有鏈片、鏈滾、襯套、鏈軸等等的零件。其中,在鏈片的製造上都是利用裁切加工,在一金屬板材上裁切出一個個分別具有兩穿孔的鏈片,所述鏈滾及襯套則是裁切預定長度的實心圓柱體,再藉由沖孔加工形成中空的管體。Due to its flexibility and better mechanical strength, the chain is often used in the mechanical field as a power transmission component. As the power of the mounting mechanism varies, the specifications of the chain are also large. For example, The chain of power transmission of large machinery is large in size and strong in structure, and the chain used in general bicycles is small in size. But regardless of the size of the chain, it usually contains parts such as links, chain rolls, bushings, chain shafts, and the like. Wherein, in the manufacture of the chain, the cutting process is performed, and a chain piece having two perforations respectively is cut on a metal plate, and the chain roller and the bushing are solid cylinders which are cut to a predetermined length. Then, a hollow tube body is formed by punching.
已知鏈條在製造鏈片的過程中,為了減少廢料並降低材料成本,都會盡可能地讓相鄰之鏈片緊靠,以便在相同面積的金屬板材上裁切出更多數量的鏈片,但無論如何的裁切,在每片鏈片成型的過程都會產生兩個對應穿孔的圓片廢料,這些圓片廢料一般都被當作價格低廉的廢料販賣。習知鏈條的製造過程雖然已盡可能地提高鏈片成型的數量,但每片鏈片在成型後都會產生兩片被當作廢料處理的圓片廢料,若能有效利用前述圓片廢料,將可降低廢料量及材料成本,本發明即針對前述缺失作改良。It is known that in the process of manufacturing a chain, in order to reduce scrap and reduce material cost, adjacent chains are as close as possible to cut a larger number of chains on the same area of metal sheet. However, in any case, in the process of forming each piece of the chain, two wafer scraps corresponding to the perforations are produced, and these disc scraps are generally sold as low-cost scrap. Although the manufacturing process of the conventional chain has increased the number of chain forming as much as possible, each piece of the chain will produce two pieces of scrap waste treated as waste after molding. If the above-mentioned wafer scrap can be effectively utilized, The amount of waste and the cost of materials can be reduced, and the present invention is directed to the aforementioned defects.

圓片廢料再加工步驟:本步驟為了將取用該等圓片廢料16以製造鏈條1之鏈片11,其主要包括一展延加工及一裁切加工。該展延加工是將該圓片廢料16壓製成圓形且直徑擴大的展壓片16’後再加以整平,整平後該展壓片16’的直徑D大於該鏈片11之長度L,且該展壓片16’的厚度等於該鏈片11的厚度。Disc Reprocessing Step: In this step, in order to take the wafer scrap 16 to manufacture the chain 11 of the chain 1, it mainly comprises a stretching process and a cutting process. The stretching process is to press the wafer scrap 16 into a circular and enlarged diameter stretched piece 16' and then level it. After the flattening, the diameter D of the stretched piece 16' is larger than the length L of the chain piece L. And the thickness of the stretched piece 16' is equal to the thickness of the chain piece 11.
又該展壓片16’具有一個圓形的外周面161,為了方便後續加工,較佳地,該等鏈片11之輪廓邊112到該展壓片16’之一最短距離H大於或等於該鏈片11之厚度。Further, the stretched sheet 16' has a circular outer peripheral surface 161. For the convenience of subsequent processing, preferably, the shortest distance H of the contour edge 112 of the chain 11 to the stretched sheet 16' is greater than or equal to the The thickness of the chain piece 11.
本實施例之裁切加工則是在該展壓片16’上裁切該具有該等穿孔111的鏈片11。由於本實施例該等鏈片11是直接由製造該初始鏈板15之圓片廢料16所製成,故本實施例之製造方法不僅可以充份利用廢料、減少廢料,亦具有節省材料成本之功效。The cutting process of this embodiment cuts the chain piece 11 having the perforations 111 on the stretched sheet 16'. Since the chain 11 of the embodiment is directly made of the wafer waste 16 for manufacturing the initial chain plate 15, the manufacturing method of the embodiment can not only fully utilize waste materials, reduce waste materials, but also save material cost. efficacy.
參閱圖1、4,本發明製造方法之一第二較佳實施例亦用來製造圖1所示之鏈條1的零件,在本較佳實施例,該零件亦為鏈片11。該製造方法亦包含:裁切初始鏈板步驟,以及圓片廢料再加工步驟,其中,裁切初始鏈板步驟與第一實施例相同,不再贅述,而圓片廢料再加工步驟同樣包括一展延加工及一裁切加工。該展延加工亦將該圓片廢料16壓製成展壓片16’,該展壓片16’呈橢圓形,故其外周面161具有兩個圓弧段162,以及兩個連接該等圓弧段162的平直段163,且該展壓片16’還具有一長軸164。而該裁切加工係於該展壓片16’上裁切出該鏈片11。Referring to Figures 1 and 4, a second preferred embodiment of the manufacturing method of the present invention is also used to manufacture the components of the chain 1 of Figure 1, which in the preferred embodiment is also a chain 11. The manufacturing method also includes: cutting the initial chain plate step, and the wafer scrap reprocessing step, wherein the step of cutting the initial chain plate is the same as that of the first embodiment, and will not be described again, and the wafer scrap reprocessing step also includes a Extension processing and a cutting process. The stretch processing also presses the wafer scrap 16 into a stretch sheet 16'. The stretched sheet 16' has an elliptical shape, so that the outer peripheral surface 161 has two arc segments 162, and two arcs are connected. The straight section 163 of the segment 162, and the tab 16' also has a long axis 164. The cutting process cuts the chain 11 from the stretched sheet 16'.
相同道理,為了達到較佳的裁切品質,本實施例該圓片廢料16在經過展延加工而形成該展壓片16’時,其長軸164大於該鏈片11的長度L,且該展壓片16’之外周面161至該鏈片11之輪廓邊112的最短距離H亦大於或等於該鏈片11之厚度。前述展壓片16’的形狀大小與製成之鏈片11更接近,故本實施例在裁切後所殘留之廢料比第一實施例更少。In the same way, in order to achieve a better cutting quality, the wafer scrap 16 of the embodiment has a long axis 164 greater than the length L of the chain piece 11 when the stretched sheet 16' is formed by extension processing. The shortest distance H from the outer peripheral surface 161 of the stretched sheet 16' to the contoured edge 112 of the chain 11 is also greater than or equal to the thickness of the chain sheet 11. The shape of the above-mentioned stretched piece 16' is closer to that of the formed chain piece 11, so that the waste remaining in the present embodiment after cutting is less than that of the first embodiment.
參閱圖1、5、6,本發明製造方法之一第三較佳實施例亦用來製造該鏈條之零件,在本較佳實施例,該零件為鏈滾12。本實施例之加工方法亦包含:裁切初始鏈板步驟,以及圓片廢料再加工步驟,其中,裁切初始鏈板步驟與第一實施例相同,不再贅述。而圓片廢料再加工步驟包括:一整型加工、一沖孔加工。即首先將圓片廢料16整平成適當直徑及高度的圓柱體16”,該圓柱體16”具有兩個平行的端面166,之後以鍛造機械對該圓柱體16”之該等端面166進行沖壓,並各別形成一凹槽167,之後再貫穿該等凹槽167,以形成一通道168,即完成該鏈滾12的製造。Referring to Figures 1, 5 and 6, a third preferred embodiment of the method of manufacture of the present invention is also used to manufacture the components of the chain. In the preferred embodiment, the component is a chain roller 12. The processing method of the embodiment also includes the steps of cutting the initial chain plate and the step of reprocessing the wafer scrap, wherein the step of cutting the initial chain plate is the same as that of the first embodiment, and details are not described herein again. The wafer scrap reprocessing steps include: one-piece processing and one punching processing. That is, the wafer scrap 16 is first flattened into a cylinder 16" of appropriate diameter and height, the cylinder 16" having two parallel end faces 166, which are then stamped by the forging machine to the end faces 166 of the cylinder 16". A recess 167 is formed in each of the grooves 167, and then through the grooves 167 to form a passage 168, that is, the manufacture of the chain roller 12 is completed.
前述製造方法的創新,同樣可以充分利用成型該初始鏈板15時所產生的圓片廢料16,以製造出符合尺寸規格的鏈滾12,由於一般鏈條1之襯套13之結構與該鏈滾12類似,故該鏈條1之襯套13亦可利用本發明該第三較佳實施例的製造方法來製造。至於該鏈條1之鏈軸14由於成圓桿狀,因此,該圓片廢料16亦可利用鍛造、整型的方式來成型,不再以圖例說明。The innovation of the foregoing manufacturing method can also make full use of the wafer scrap 16 generated when the initial chain plate 15 is formed, to manufacture the chain roller 12 conforming to the size specification, and the structure of the bushing 13 of the general chain 1 and the chain roll Similarly, the bushing 13 of the chain 1 can also be manufactured by the manufacturing method of the third preferred embodiment of the present invention. As the chain shaft 14 of the chain 1 is formed into a round rod shape, the wafer scrap 16 can also be formed by forging and shaping, and will not be illustrated by way of illustration.
由以上說明可知,本發明鏈條零件的製造方法不僅創新,亦可充分利用原本以廢料形式處理之圓片廢片16,上述製造方法確實可以依據該圓片廢片16的重量,製作成尺寸規格不同之鏈條1的鏈片11、鏈滾12、襯套13及鏈軸14等等的零件,故本發明確實可以充份運用鏈條1製造時裁切的廢料,並因此達到降低廢料量及材料成本的功效。As can be seen from the above description, the manufacturing method of the chain component of the present invention is not only innovative, but also can fully utilize the scrap scrap 16 which is originally processed in the form of waste. The above manufacturing method can be made into a size according to the weight of the scrap scrap 16 of the disc. Different parts of the chain 11 of the chain 11, the chain roller 12, the bushing 13 and the chain shaft 14 and the like, so the present invention can fully utilize the scraps cut during the manufacture of the chain 1, and thus reduce the amount of waste and materials.
