電極板彎曲模具設(shè)計CAD/CAM中文摘要
畢業(yè)設(shè)計的主要內(nèi)容是電極板生產(chǎn)所需的工藝設(shè)計、模具設(shè)計。電極板屬于典型的沖孔彎曲件，在進(jìn)行工藝設(shè)計之前，先根據(jù)產(chǎn)品的圖紙，分析沖壓件的結(jié)構(gòu)形狀尺寸精度和材料性能，提出各種可能成形的工藝方案。通過分析、計算，論述各種方案的工藝特點和經(jīng)濟(jì)效益，確定較好的工藝方案，進(jìn)而確定生產(chǎn)工序及其所需的各種設(shè)備，然后進(jìn)行模具設(shè)計。模具設(shè)計了整個三道工序，其中它包括了裁料、落料沖孔、彎曲三道工序，針對三套模具，我設(shè)計并繪制了裝配圖，并就其中的彎曲模畫了零件圖。
關(guān)鍵詞：電極板、模具設(shè)計、沖孔、彎曲

The Stamping Craftworks and Mould of Wide-screen color LCD screen
Abstract
 The main content of the essay are technological design and mould design what the Haire television chassis’s production require. The Haire television chassis a kind of the model stretch productions, before carrying on the technological design, according to the product blueprint, analyzes pressing part’s structure, the size precision and the material performance first, proposes each kind of possibility forming craft plan. Through the analysis, the computation, elaborate various plans craft characteristic and the economic efficiencv, determined the good craft plan ,then the determination production working procedure and needs each kind of equipment, then carries on the mold design. The mold has only one set: Falls the material forming superposable die, completes falls the material working procedure and formed working procedure; In view of this set of mold, I designed and have drawn up its final assembly drawing and the detail drawing.
Key words: compound die; stretch; blanking; distortion.
