| The automobile industry face flinty competition after our country joins the WTO, especially the automobile parts and assemblies industries. They were subjected to the unprecedented impact. FAW Wheel Company is one of automobile parts companies. Its main operation is provides parts for all kinds of domestic automobile factories. With foreign automobile factories entering, we may lose our advantage. Therefore, we must expand our market, looking for a way to adapt to new situation. There is 60% to 70% automobile metal parts are made use the techniques of forging and punch. Punch is a kind of important instrument that completes the metals shaping, it is one of basic, traditional and important metal machine methods. Punch parts'manufacturing techniques and quantities will influence the quantity and costs of automobile directly. Dies and machine are two key factors that will decide parts'quantity, accuracy and produce efficiency. Advanced punch machines only work with advance dies can take a good result and obtain benefit. Die becomes the main techniques in equipment of industrialization produce, it is widely used in machine, electronics, light industry, automobile, spin, aeronautics etc. industry field. Dies are used to produce 60%～90% parts and assemblies in these industry fields. According to the estimate of Ford automobile company, four greatest management expenditure, designing, manufacturing, original material and labor force, the product designing expenses only 5% of the product cost, but it decide 75% total manufacturing cost and 80% product quantities. Development of die technique relates to quantity, efficiency, renewing and development of the product directly. In order to improve designing quantity of die, shorten it's design, manufacture, adjusting time and lower design cost, achieve the purpose of shorten the product development cycle finally, equipment design method is chose as the research object. The problem that appear in die development and molding process are detail analyzed and compared, a series simple, practical and valid molding tool development method are summed up according the characteristics of FAW Wheel Company's product, with the new method, period of molding tool development and manufacture are shorten greatly. The industry engineering (the brief name IE) is an edge course that including many factors such as person, material, equipments, information and energy...etc. the course layout, design, improve, control these main factors, it is the combine of technique and managements. It use natural sciences, such as mathematics and physics...etc. and social sciences, especially the engineering technique theories and methods, it provide powerful support in technique way for the goal of manufacturing, management and the service system low cost, high-efficiency and efficiently benefit. In improved nations, IE has become a important factor of product the development and economies to increase, but in China, the IE is a newly arisen course, it still in a stage of concept research and ideas to expand. Work research is important basis technique in IE system for lower cost, improve quantity and increase produce efficiency. The characteristic of work research lies in that in the conditions of few or no invest, increasing produce efficiency so that improve the benefit and ability of compete. Work research becomes the first technique as a tool to improve produce efficiency all over the world. The whole process of the foundation IE is use procedure analysis, operating analysis, and action researches within the work research method, obtain the best procedure and methods, then use work determine method to decide standard time. In paper writing process, reasonable work method is made use traditional IE work research technique, use it's work determine technique to decide standard time. The main task of our company is product design-technological design-molding tool design -the molding tool manufacturing-try the mold-batch produce product according to the demand of the consumer. The design of the automobile wheel product can basis 《the nation( industry) standard of the automobile wheel collection》and 《correlative nation( industry, business enterprise) automobile wheel standard collection》. The design of the technique and molding tool is determined by experiences of designer, the work point of our company also lies in this, if these two designs are impertinency, the development period, manufacturing cost and usage cost will be affected directly. Technique center of our company response for design work completely, manufacturing work is done by equipment company or machine workshop of our company. Actuality of our company is: Overcapacity; Economic benefits is general; we can't get hold of much batch contract, though new product has been developing continuously. There are many factors that contribute to the bad present condition of our company. One of important reasons can be obviously seen. The quality and the efficiency of new product development are important problems in the technique department. Because the sample can't be provided in time or it is unqualified, as a result, we have lost many opportunities. The most important point of product deliver cycle is die design, molding and adjust In new product development process, draggle of whole die design and manufacturing method and design process result in the problem ultimately, therefore, it is a effective method to speedup new product develop speed that investigate equip design method and... |
