              沖壓件是靠壓力機和模具對板材、帶材、管材和型材等施加外力,使之產(chǎn)生塑性變形或分離,從而獲得所需形狀和尺寸的工件(沖壓件)的成形加工方法。沖壓和鍛造同屬塑性加工(或稱壓力加工),合稱鍛壓。



              Stamping is a forming and processing method for workpiece (stamping parts) by applying external force to plate, strip, pipe and profile by press and die to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure machining).


              在沖壓件行業(yè)里,沖壓有時也稱板材成形,但略有區(qū)別。所謂板材成型是指用板材、薄壁管、薄型材等作為原材料進行塑性加工的成形方法統(tǒng)稱為板材成形,此時,厚板方向的變形一般不著重考慮。

              In the stamping industry, stamping is sometimes referred to as sheet metal forming, but there is a slight

               The so-called sheet forming means the forming method of plastic forming with sheet, thin-walled tube and thin material as raw material, which is called sheet forming. At this time, the deformation of the thick plate is generally not cidered.





              薄板:鋸削時盡可能從寬面鋸下去,若必須從窄面鋸下時,可用兩塊木墊夾持,連木塊一起鋸下,也可把薄板直接夾在虎鉗上,用手鋸作橫向斜推鋸,使鋸齒與薄板料接觸的齒數(shù)增加,避免鋸齒崩裂。


              Thin plate: sawing as far as  as wide as when sawing. If must be sawed from narrow surface, it can be held by two wooden blocks and sawed together with wooden blocks. The sheet can be clipped directly to the vise, and a hand saw is used as a transverse oblique saw to increase the number of teeth contacted with the sheet material and avoid the crack of the saw teeth.


              五金沖壓模具的安裝是否正確合理,不僅影響五金沖壓件的產(chǎn)品質(zhì)量和精度,還會影響模具的工作壽命及生產(chǎn)安全。并且熟練掌握沖壓模具的安裝也是每個沖壓工應該掌握的技巧。


              Whether the installation of the metal stamping die is correct and reasonable, not only affects the quality and precision of the metal stamping parts, but also affects the working life and production safety of the die. And skilled in stamping die installation is also a skill that every stamping worker should master.
