limit column: the limit column is a cylindrical part that limits the minimum closing height of the die

locating pin (plate): locating pin (plate) is a part that ensures that the process part has a constant position in the mold. It is called locating pin or locating plate because of its different shape

fixed plate: the fixed plate is a plate-shaped part for fixing the punch

fixed discharge plate: the fixed discharge plate is a discharge plate fixed in a fixed position on the die

fixed stopper pin (plate): the fixed stopper pin (plate) is a stopper pin (plate) that is fixed in the mold

unloader: unloader is a non plate part or device that unloads work (sequence) parts from the outer surface of punch

discharge plate: the discharge plate is a fixed or movable plate-shaped part that removes materials or work (sequence) parts from the punch. The discharge plate is sometimes integrated with the guide plate and also plays the role of material guide. It is still called the discharge plate

unloading screw at the 1st "pioneer Cup" future technological innovation competition held recently in Shenzhen, which aims to improve China's independent innovation ability and increase the transformation of advanced scientific and technological achievements: the unloading screw is a screw fixed on the elastic unloading plate, which is used to limit the static position of the elastic unloading plate

scrap cutter: there are two types of scrap cutters. 1。 A cutter installed on the flange trimming die of a drawing part for cutting off the whole circle of trimming waste to facilitate removal. 2。 A cutting knife installed on a press or die for cutting strip (strip, roll) shaped waste materials according to a fixed length to facilitate removal
