【正文】 定位零件定位，壓力機(jī)滑塊帶動(dòng)上模下壓，在模具工作零件（即凸模、凹模）的作用下坯料便產(chǎn)生分離或塑性變形，從而獲得所需形狀與尺寸的沖件。復(fù)合級(jí)進(jìn) ——在一副沖模上包含復(fù)合和級(jí)進(jìn)兩種方式的組合工序。在實(shí)際生產(chǎn)中，當(dāng)沖壓件的生產(chǎn)批量較大、尺寸較少而公差要求較小時(shí)，若用分散的單一工序來(lái)沖壓是不經(jīng)濟(jì)甚至難于達(dá)到要求。因此可以說(shuō)，如果生產(chǎn)中不諒采用沖壓工藝，許多工業(yè)部門(mén)要提高生產(chǎn)效率和產(chǎn)品質(zhì)量、降低生產(chǎn)成本、快速進(jìn)行產(chǎn)品更新?lián)Q代等都是難以實(shí)現(xiàn) 的。 沖壓地、在現(xiàn)代工業(yè)生產(chǎn)中，尤其是大批量生產(chǎn)中應(yīng)用十分廣泛。（3）沖壓可加工出尺寸范圍較大、形狀較復(fù)雜的零件，如小到鐘表的秒表，大到汽車(chē)縱梁、覆蓋件等，加上沖壓時(shí)材料的冷變形硬化效應(yīng)，沖壓的強(qiáng)度和剛度均較高。主要表現(xiàn)如下。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。 Products rough start calculating the size is calculated at a convenient but does not affect mold forming on the premise familiar to simplify the model. The paper also forming part of the stamping dies and other relevant parts of the principle of choice and select the method described. Stamping parts from the design of the first stamping on the production process to be designed to cover iron of chipfor stamping process of analysis and calculation and then calculated on the basis of analysis and see stamping design information related to determine the programme stamping process, and on this basis The process of determining the relationship, and then entered the concrete structure of the die design. On this basis, all of the major parts stamping die design and size, the large number of reference during the relevant information with the press and read all kinds of stamping Manual and calculated to determine the specific mold of the structure and Size, by the calculation and constant changes in the careful guidance of teachers under the guidance of patient care and continuously repeated changes to draw the final 1 assembly and 3 parts map. Through this I graduated from design to understand and master the many practical things with my internship in the production of which would like to see some of the things, with some of their own harvest. In this special thanks to college, school teachers for giving me this opportunity and the careful guidance.
