石英表鐵芯彎曲級進(jìn)模
摘 要
本設(shè)計題目為石英表鐵芯彎曲級進(jìn)模設(shè)計，體現(xiàn)了沖壓工藝部分的設(shè)計要求、內(nèi)容及方向，有一定的設(shè)計意義。通過對該零件模具的設(shè)計，進(jìn)一步加強(qiáng)了設(shè)計者沖壓工藝的基礎(chǔ)知識，為設(shè)計更復(fù)雜的沖壓模具做好了鋪墊和吸取了更深刻的經(jīng)驗。
本設(shè)計運(yùn)用沖壓成形工藝及模具設(shè)計的基礎(chǔ)知識，首先分析了制件的變形及性能要求，為選取模具類型做好了準(zhǔn)備；然后計算沖壓凸模和凹模的尺寸，便于選取標(biāo)準(zhǔn)的凸模和凹模做準(zhǔn)備；最后分析制件的結(jié)構(gòu)，以便確定凸、凹模的形狀，分析制件材料力學(xué)性能及變形過程中的特點，以便計算沖壓力的大小來選取壓力機(jī)類型。
本設(shè)計是沖孔、落料、彎曲的級進(jìn)模具，設(shè)計時主要考慮了不同工位之間的距離，以確定毛坯制件的位置及每次進(jìn)給的距離。同時考慮各個不同工位之間動作的協(xié)調(diào)一致性及各個工位模具的磨損量。

Curved plate bending punching and cutting mode
Abstract
The design for the curved plate bending subject punching die cut design, stamping process embodies all the design requirements, content and direction of the design of a certain significance. Through the design of the mold parts, has further strengthened the basis of the designers of stamping process knowledge, for the design of more complex stamping die to do a good job of paving the way and draw a more profound experience.
The design of the use of punch forming process and die design of the basic knowledge, the first analysis of the deformation of parts and performance requirements, in order to select the type of ready to die; and then calculating the punch press and die size, easy to select the standard punch and to prepare die; the final analysis of the structure of parts in order to determine the convex, concave die shape, analysis of the mechanical properties of materials and parts in the process of the characteristics of deformation for the purpose of calculating the size of red pressure to select the type of press.
The design is punching,cutting, bending progressive die, the main consideration for the design of the different distance between the position to determine the rough location of parts and the distance between each feed. Taking into account the different position of the coordinated action between the various work places and mold wear
