汽车内护板支架工艺分析及模具设计

摘要：随着全球经济的发展，新的技术革命不断取得新的进展和突破，技术的飞跃发展已经成为动世界经济增长的重要因素[2]。中国汽车产业的飞速发展，汽车零部件制造也得到了前所未有的发展，促使工业产品越来越向多品种、小批量、高质量、低成本的方向发展，为了保持和加强产品在市场上的竞争力，产品的开发周期、生产周期越来越短，于是对制造各种汽车产品的模具也提出了新的要求，研究内护板支架的冲压工艺和模具对提高汽车冲压件质量和提高生产效率，降低生产成本，提高国有汽配市场占有率具有现实意义。

本文通过积极运用学习实践中所学到的知识对汽车后门内护板支架进行分析，确定生产工艺方案，制定出内护板支架产品的控制计划书，并对内护板支架的生产模具进行设计。

通过产品及工艺的分析，制造出低生产周期、低成本、高质量、高效率的模具，从而提高产品的质量和降低工人劳动强度，降低生产成本。

Boards within the stent technology analysis and die design

Abstract:With the global economic development, the new technological revolution con-tinue to achieve new progress and breakthroughs in technology ,leap in development has become a dynamic growth of the world economy an important factor. China's rapid de-velopment of the automotive industry, automotive components manufacturing industry has been an unprecedented development[12], promote industrial products to more and more variety, low-volume, high-quality, low-cost direction, In order to maintain and strengthen the product on the market competitiveness of the product development cycle, more and more short production cycle, so the manufacture of various automotive prod-ucts also made a mold of the new requirements, Study-boards support the stamping pro-cess and die stamping parts to improve vehicle quality and increase production efficiency, reduce production costs and increase market share of the state-owned auto parts is of practical significance.

By studying and practicing the positive use of the knowledge acquired in the car af-ter the building-boards stent for analysis to determine the production of the programme, developed in-stent products for the control plan, and in-boards scaffold production mold design [13].

Through product and process analysis, creating the mold which has a low production cycle, low-cost, high-quality, high efficiency, thereby enhancing the quality of products and reduce labor intensity of workers, reduce production costs.
