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 equi
