一、概述在机器制造业中,冷冲压生产是一种高效的加工方法。它能把不同性质和规格的板料在压力机上通过冲模加工成所需要的工件,大至飞机、汽车的外壳,小至钟表、仪器的零件。在日常生活中所接触到的用具也有一部分是冲压件,如烧饭的铝锅、金属的钢笔套子、服装上的揿钮等。要进行冲压工作就必须有冲模,冲模的精确度直接影响到被冲零件的精度,所以冲模的制作是一项比较细致和费时的工作。随着我国工农业生产的发展,冲模的加工方法也有了很大的改进。就拿制造冷冲模的设备来说,我国 First, an overview In the machinery manufacturing industry, cold stamping production is an efficient method of processing. It can be of different nature and specifications of the plate in the press through the die into the required parts, ranging from aircraft, car shell, as small as watches, parts of the instrument. Some of the items that come into contact with daily life are also stampings, such as aluminum pots for cooking, metal pen covers, buttons on clothing, and more. To carry out the stamping work must have a die, die accuracy directly affects the accuracy of the parts being punched, so the die is a more detailed and time-consuming work. With the development of industrial and agricultural production in our country, the processing methods of die have also been greatly improved. Take the manufacture of cold die equipment, my country
