test die meaning in English

测试芯片

Based on calculation method on unfold size and piece form , theory analysis and research are given on ellipse , circle tube , box as equal - high , irregular , unequal - high , irregular piece , process and condition on possibility of drawing are introduced , through calculation coefficient , number of drawing , drawing testing dies are made , results are given , it is similar to calculation method , in the same time , complex drawing presswork is planed , to avoid wrinkle , critical in drawing process . in this paper , die designing is introduced based on complex drawing unfold size calculation , press center is automatic calculated , apartments of press tools are calculated too with material mechanic production process and press form are better , period of die designing is to reduced , and cost of product is lower
对基于复杂拉深件展开尺寸计算的模具设计也作了详细的论述，指出了现有复杂拉深件模具设计制造程序的不合理性，本文在复杂拉深件展开尺寸基础上自动生成冲裁中心、冲裁周长，运用材料力学中杆件强度及抗失稳条件，实现对冲压模具参数的自动计算，简化了冲压模具弹性元件、打料装置的设计过程，给出了冲压模具结构设计流程，使得模具材料核算，制造过程，冲压方式更趋合理，缩短了模具设计制造周期，降低了产品生产成本。
