摘要
在汽車彈簧生產(chǎn)工藝中，卷耳包耳工序是關(guān)鍵。單工位彎耳機是對汽車鋼板彈簧主板進行切頭彎耳一次成型的液壓設(shè)備。首先，文中提出了幾種鋼板切頭彎耳的可行性方案以及工藝措施，并進行了分析、比較、論證，選出最佳方案。其次，確定出單工位液壓彎耳設(shè)備主要需要的機構(gòu)及運動，并選定出各自具體的運動結(jié)構(gòu)方案。再通過以上分析、考慮，綜合確定出設(shè)備的總體運動結(jié)構(gòu)方案。利用所給有關(guān)數(shù)據(jù)，對設(shè)備的各個機構(gòu)進行動力、運動設(shè)計計算，確定各機構(gòu)的尺寸。繪制總體裝配圖及部件圖，確定本設(shè)備的布局尺寸，設(shè)計出達到要求的汽車鋼板彈簧的單工位液壓彎耳。而且在最后對整個設(shè)計工作進行總結(jié)、歸納，對部分設(shè)計問題進行分析說明。

Abstract
Bending is the key in the plate spring production.This description is a general design and elucidation relevant to automobile steel plate bending machine what is used as cutting-out the head of the plate spring and bending the plate spring. Designed in the description is a single working hydraulic plate bending equipments.
First, in this description, it raised several executable programmers and posed several technological specifications to product the automobile plate spring. And then we proceeded to compare and argued the programmers. Be virtue of the argument, we selected the best project. Then make sure the main requirements of the machines and sport construction of the single working hydraulic plate bending equipments, and definitude the specific structures. Then we were virtue of these researches, and combined various opinions, we made selection out concretely the project again. Sum up the above analysis and consider again, synthesize to make sure the total sport construction of the equipments and the project. Then we can be virtue of the parameter and refer to the reference book, make use of an each organization for count, we proceed to design and calculate of the motive power and sport movement of the equipment, and make sure the size of each organization.
Then we drafted the general assembly diagram and parts assembly diagram of this equipment, certain this equipments attain the requests that we needed to product the spring. At finally proceeds to whole design work, and we can get the equipment of the simplex working bending machine of the automobile spring.
Key word: Hydraulic equipment Bending equipment A single working bending equipment
