ü   What is a stamping?

Stamping is a type of cold stamping process in which a material (metal or non-metal) is hit with the aid of conventional or special-purpose punching equipment to cut, bend, or shape it into the shape and dimensions of the finished product specified by the mold. Press processing can be roughly divided into several different processing types such as shearing, bending, forming, and drawing.

Stamping can also be said to rely on the press and mold on the plate, strip, pipe and profile and other external force, so that it produces plastic deformation or separation, so as to obtain the desired shape and size of the workpiece (stamping) forming method. Stamping and forging are plastic processing (or pressure processing), collectively known as forging. Stamped blanks are mainly hot-rolled and cold-rolled steel sheets and strips. Of the steel in the world, 60 to 70% are sheet metal, most of which are stamped and finished.
Press processing is the use of conventional or special press equipment power, so that the sheet material in the mold directly by the deformation force and deformation, so as to obtain a certain shape, size and performance of the production of parts of the technology. Sheets, moulds and equipment are the three elements of stamping. Press processing temperature is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a stamping method commonly used for sheet metal. It is one of the main methods of metal plastic processing (or pressure processing), and it is also affiliated with material forming engineering technology.
The stamping die is called stamping die, or die. Dies are special tools for the batch processing of materials (metal or non-metal) into the required stampings. Stamping is very important in stamping. There is no punch that meets the requirements. Batch stamping production is difficult to carry out. Without advanced stamping, advanced stamping technology cannot be realized. Stamping processes and dies, stamping equipment and stamping materials constitute the three elements of stamping. Only when they are combined can stampings be obtained.

ü   Stamping application range:

Precision machinery, aircraft, automobiles, locomotives, ships, munitions, watches, motors, electronics, home appliances and furniture and many other product parts. Recently, many machined products, castings, die castings and forged products have been gradually replaced by stampings.


ü   沖壓件簡介

沖壓是一種冷沖壓加工方式,係藉助於常規或專用沖壓設備的動力重擊材料(金屬或非金屬),將其裁切、折彎或塑造成模具所規範的成品形狀與尺寸中。沖壓加工大致可區分成剪切、彎曲、成型引申等幾種不同的加工型式。
沖壓也可以說是靠壓力機模具對板材帶材管材型材等施加外力,使之產生塑性變形或分離,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。沖壓的坯料主要是熱軋和冷軋的鋼板和鋼帶。全世界的鋼材中,有6070%是板材,其中大部分經過沖壓製成成品。
沖壓加工是藉助於常規或專用沖壓設備的動力,使板料在模具裡直接受到變形力並進行變形,從而獲得一定形狀,尺寸和性能的產品零件的生產技術。板料,模具和設備是沖壓加工的三要素。按沖壓加工溫度分為熱沖壓冷沖壓。前者適合變形抗力高,塑性較差的板料加工;後者則在室溫下進行,是薄板常用的沖壓方法。它是金屬塑性加工(或壓力加工)的主要方法之一,也隸屬於材料成型工程技術。
沖壓所使用的模具稱為沖壓模具,簡稱沖模。沖模是將材料(金屬或非金屬)批量加工成所需沖件的專用工具。沖模在沖壓中至關重要,沒有符合要求的沖模,批量沖壓生產就難以進行;沒有先進的沖模,先進的沖壓工藝就無法實現。沖壓工藝與模具沖壓設備沖壓材料構成沖壓加工的三要素,只有它們相互結合才能得出沖壓件

ü   沖壓的運用範圍:

精密機械、飛機、汽車、機車、輪船、軍火、鐘錶、電機、電子、家電和家俱等諸多產品零件。近來許多機械加工品、鑄件、壓鑄品及鍛造品已逐漸被沖壓品取代。
