摘 要
彎曲件的工序安排應(yīng)根據(jù)工件形狀的復(fù)雜程度﹑精度要求的高低﹑生產(chǎn)批量的大小，以及材料的機械性質(zhì)等因素進行考慮。
保油箱固定拉杠環(huán)是一個對稱彎曲件，具有良好的工藝性，不僅可以提高制件精度和節(jié)省原材料，而且大大簡化彎曲工藝過程和模具設(shè)計。
此套模具的總體設(shè)計思想是把經(jīng)濟、合理、實用作為最基本的出發(fā)點，從坯料排樣到模具設(shè)計與制造，都嚴(yán)格遵循。
整套模具設(shè)計過程，涉及到許多工序。零件工藝性分析首先考慮制件的精度要求，然后對各尺寸以及形狀進行分析；工藝方案擬定顯得尤為重要，關(guān)系到設(shè)計的成?。桓鞴に噮?shù)的計算和確定必須做到有據(jù)可依，以確保計算結(jié)果的可靠性；模具的設(shè)計與制造，需考慮實際生產(chǎn)的可操作性制造加工的難易程度，以及其維護的方便程度來確定每個零件的形狀和整套模具的結(jié)構(gòu)形式。
隨著工業(yè)的發(fā)展，汽車行業(yè)的興起，彎曲工藝將會日益突出它的重要性。

ASSUARE THAT THE FUEL TANK DRAWS THE THICK STICK AND SURROUNDS THE TRIMMING DIE TO DESIGN REGULARLY

ABSTRACT

Arrange to follow the complexity of the form of the work piece in crooked process of one. Level that the precision requires. The size of production lot, and the factors, such as mechanical nature of the material ,etc. are considered.
Assuare fuel tank regular to draw thick stick ring first symmetrical crooked one, have good crafts, not only can improve and make a precision and save the raw materials but also simplify the crooked craft course and mold design greatly .
This set overall design philosophy of mould economy, rational practical to regard the most basic starting point as, arrange kind from the blank to mould design and manufacture, all follow strictly.
A whole set of mould design process, involve a lot of processes. The craft of the part is analysed: Consider precision to make piece require , analyse to every size and form at first; Draft that seems particularly important, concern the success or failure designed in craft scheme; Every craft calculation and confirm and must accomplish and have and according to can be depended on, so as to ensure the dependability of the result of calculation of parameter; Design and manufacture of mould, need effectiveness complexity that manufacture processed produced actually to consider, and its one that maintained helped the degree confirm the form of each part and structure form of a whole set of mould .
With the development of industry, the rise of the automobile trade, the crooked craft will stress its importance day by day .
KEY WORDS: Crooked, the thought, require, the process, design
