摘要
本文分析了電位器接線片的成型工藝特點(diǎn)，其中包括利用對(duì)工件展開圖的尺寸計(jì)算、工件的工藝分析、沖裁力與拉深力的計(jì)算、模具設(shè)計(jì)的難點(diǎn)，確定了級(jí)進(jìn)模的排樣方案和模具總體結(jié)構(gòu)。該級(jí)進(jìn)模有沖裁、拉深、整形、脹形等7個(gè)工位。詳細(xì)介紹了凸模、凹模、固定板、卸料裝置等零部件的設(shè)計(jì)和制造，以及壓力機(jī)的選擇。同時(shí)闡述了模具的工作過(guò)程、各成形動(dòng)作的協(xié)調(diào)性、以及凸模和凹模鑲塊的裝配間隙，并制定典型零件的加工工藝。

Title Design of the Stamping Process and the

Progressive Die for the telegraphese connection
(i) Abstract
This paper analyzes the technical characteristics of the telegraphese connection product stamping，including the size calculation of the part technical analysis, the calculation of the punching force and drawing force, the difficulties of die design, making sure the layout project and the die general structure. The progressive die could complete seven processes that include punching, drawing, shaping and so on. The high-speed punching machine has been used during the process of producing. It introduces the design and manufacture of the punch, the die, the stripping device, the pushing device, and the blanking holders in details. And it also expatiates the working process of the die, the coordination about each motion of figurations, the assemble clearance of the punch and die, even including the way to establish the manufacture process of the typical parts.
