The classification of the metal stamping die is analysed

Die is indispensable in the production of stamping die. Die basically can be divided into simple mode, continuous mode and composite mode 3 kinds. ( 1) Simple punch die is simple with a punch stroke only completed a process of punching die. Is a simple punching die, blanking and punching with simple die assembly drawing. Work article of material on the die along the two guide sent to between 9, touching the dowel pin 10 so far. The punch press down, down the parts ( Or waste) Enter the concave die hole, and the strip clamp punch and return with punch upward movement. Stock when encountering the stripper plate 8 ( On the die) Article is pushed down, such, is expected to continue to send into between the guide plate. Repeat the above action, at the first two parts. ( 2) Continuous punching die punch stroke at a time, in the mold at the same time on different parts of the complete collection of the stamping process of mold, referred to as the continuous mode. Work positioning pin 2 rushed out of the positioning hole in advance, the downward movement of upper die, blanking punch 1, piercing punch 4. When the upper die return, stripper plate 6 off the waste from the punch. At this time again to send into the blank 7 ahead, execute the second cutting. So, every time send into distance is controlled by blocking pin. ( 3) Compound dies during a stroke, on the same part mould complete collection of stamping process of die at the same time, known as the compound die. The biggest characteristic of composite modulus is one of the mould intensive 1. Intensive cylindrical blanking punch edge, inner hole is deep drawing die. When the slide block with intensive downward movement, the material in the first place in the intensive 1 and 4 lagged blanking die material. Fall of materials is lower die drawing punch 2 to resist, slider to continue downward movement, die with the downward movement of deep drawing. Ejection device and discharger on the slider 3 moulds 9 launch return in deep drawing. Composite modulus is suitable for high yield, high precision stamping parts.
