基于pro/e的接線墊片級進模的設(shè)計及凸模的加工仿真
摘要：級進模精度高、壽命長，其工作元件常采用高速鋼或硬質(zhì)合金鋼制造。適用于制件的大批量生產(chǎn)。制件質(zhì)量可靠、穩(wěn)定，及制件尺寸的一致性好。級進模結(jié)構(gòu)復(fù)雜，制造精度高，調(diào)試，維修困難，價格昂貴。本文作者從工藝的合理性出發(fā)，分析了接線墊片精度特點，以及在加工過程中的控制點，然后在滿足加工精度的基礎(chǔ)上充分考慮節(jié)約成本確定了接線墊片最優(yōu)化的沖裁加工工序；緊接著通過熟悉各類模具的加工特點及內(nèi)部結(jié)構(gòu)，完成模具總體結(jié)構(gòu)分析；隨后作者進行毛坯尺寸、排樣、工序尺寸、沖壓壓力、壓力中心、模具工作部分尺寸等工藝計算，力爭以最好的性價比設(shè)計了模具各零件的結(jié)構(gòu)及裝配關(guān)系，在此基礎(chǔ)上確定模具的外形，完成了裝配圖和非標(biāo)準(zhǔn)的零件圖。最后確定壓力機類型及主要參數(shù)。

Designing for wiring pads by progressive die based on pro / e and the simulation of core plate
Abstract: Progressive Die ,with high precision, long life, its components are often used high-speed steel and carbide steel, what is applicable to the high-volume production. Products have good quality, stability, and consistency of a good-sized parts. Progressive Die with complex structure and demands high precision manufacturing, commissioning, maintenance difficulties, which is very expensive. Author of this text proceed from rationality of the craft, analyse character of the , and the control point in the course of processing, Consider and economize cost confirm wiring pads blanking that shelf optimizes most process the process fully on the basis of satisfying the machining accuracy; And then pass the processing characteristic familiar with all kinds of moulds and inside structure, Finish the ensemble architecture analysis of the mould ; Author carry on blank size, arrange kind, process size, punching pressure, pressure in the center afterwards, mould work some size,etc. craft calculate, Strive to design the structure of every part of the mould and assembly relation with the best cost performance, Confirm the appearance of the mould on this basis, has finished the installation diagram and non-standard part picture. Confirm the type of the press and main parameter finally.
Key words: Progressive Die; Arrange kind；automatic punching machine
