刹车盘铸造说明书

摘要

目前，国内汽车（主要是轿车）刹车盘的出口市场已经形成一定规模，仅就铸件来说，年产量（出口量）估计在 20万吨左右。由于刹车盘出口主要针对的是配件市场，外商定货品种繁杂，而每个品种生产，批量不大。另一方面，刹车盘铸件属薄壁小件，技术要求高，而国内生产出口刹车盘的企业，大多采用手工造型，粘土砂湿型，冲天炉熔炼铁液，成分变化较大，给生产技术管理和铸件质量控制带来一定难度，个别厂家铸件废品率居高不下，直接影响企业的经济效益和出口业务。本文主要对金属型覆砂铸造刹车盘的工艺及工艺装备进行设计。

通过对零件图的详细分析，明确了各项技术指标。拟定铸造工艺方案，包括选择铸造和造型方法等。完成砂芯设计、浇冒口设计和射砂工艺装备设计。绘制零件图、装配图、工艺流程图等。

关键词：金属型覆砂砂芯模板刹车盘

Abstract

Currently, domestic vehicles (mostly cars) Brake export market, market has formed a certain scale, just from the casting, the annual production (exports) is estimated at 20 million tons. As the brake disc main export market for the parts, foreign orders is complex variety and every variety of production is not volume. On the other hand, small pieces of brake disc casting is thin, technically demanding, while domestic production and export enterprises brake disc, mostly by hand modeling, Green Sand, cupola melting iron, composition changed greatly, to the production technology casting quality control management and bring some degree of difficulty, the high rejection rate for individual manufacturers to cast a direct impact on economic efficiency of enterprises and export business. In this paper, the metal brake discs with Sand Casting design process and technical equipment.

Through detailed analysis of the parts diagram, defines the technical indicators. Developed casting process, including the choice of casting and modeling methods. Complete sand core design, casting riser design and the design Shooting technical equipment. Drawing parts and assembly drawings, process flow diagrams .

Key words: Metallic Sand Sand core Template Brake Disc
