鈑金加工制造過(guò)程的原材料是軋制過(guò)程的輸出，通常情況下，金屬片是作為標(biāo)準(zhǔn)尺寸的扁平矩形片出售的，如果薄片很長(zhǎng)，則可能是卷狀。因此，任何鈑金工藝的第一步都是切割正確的形狀，并從較大的工作表上選擇“空白”。鈑金加工是許多工業(yè)的重要過(guò)程，這些工業(yè)是家用電器（冰箱，洗衣機(jī)，烘干機(jī)，吸塵器等），電子產(chǎn)品（DVD和CD播放器，音響，收音機(jī)等）的最大制造商之一，放大器等），玩具和個(gè)人電腦。這些產(chǎn)品中的大多數(shù)具有通過(guò)切割和彎曲金屬板制成的金屬外殼。我們看一些基本的鈑金切割和成形工藝。The raw material used in sheet metal manufacturing is the output of the rolling process. Normally, sheets are sold as flat rectangular sheets of standard size. If the sheets are long, they may be rolled. Therefore, the first step in any sheet metal process is to cut the correct shape and select the "blank" from the larger worksheet. Sheet metal processing is an important process in many industries, including household appliances (refrigerators, washing machines, dryers, vacuum cleaners, etc.), electronic products (DVD and CD players, audio, radio, etc.), toys and personal computers. Most of these products have metal shells made by cutting and bending metal plates. Let's look at some basic sheet metal cutting and forming processes.
精密鈑金加工中剪切與使用剪刀剪切一張紙的過(guò)程相似，但是，使用的機(jī)器有點(diǎn)不同，有兩種典型的用于切割金屬板的機(jī)器-第一種是剪切機(jī)，它有一個(gè)長(zhǎng)刀片，用于切割直線；它被用來(lái)將長(zhǎng)片金屬切成較小的片材。這種操作與剪紙機(jī)的操作類似：金屬片保持在硬化模具的頂部，剪切刀片向下切割，通常由電動(dòng)或液壓沖頭驅(qū)動(dòng)。
Precision sheet metal cutting is similar to the process of cutting a piece of paper with scissors, but the machines used are somewhat different. There are two typical machines for cutting sheets of metal - the first is a shearing machine, which has a long blade for cutting straight lines; it is used to cut long pieces of metal into smaller pieces. The operation is similar to that of a paper-cut machine: the sheet metal is kept at the top of the hardened die, and the cutting blade is cut downward, usually driven by an electric or hydraulic punch.
另一個(gè)金屬板沖孔機(jī)-切割工具是一個(gè)沖床，一塊硬工具鋼，它是沖壓在板上切開(kāi)一個(gè)洞。沖頭是一個(gè)轉(zhuǎn)塔沖床-轉(zhuǎn)臺(tái)是一個(gè)旋轉(zhuǎn)刀架，可以容納幾十個(gè)不同形狀和大小的沖模，典型的形狀是矩形和圓形的。通過(guò)一系列的沖壓，可以切出長(zhǎng)槽。一個(gè)典型的沖孔操作類似于您可能已經(jīng)用來(lái)打孔來(lái)將紙張夾在三環(huán)活頁(yè)夾中的打孔紙的打孔操作。
Another sheet metal punch - cutting tool is a punch, a piece of hard tool steel, it is punched on the board to cut a hole. The punch is a turret punch - turntable is a rotating tool holder, can accommodate dozens of different shapes and sizes of punches, the typical shape is rectangular and circular. Through a series of punching, long slots can be cut out. A typical punching operation is similar to a punching operation that you might have used to punch paper into a three-ring binder.
