随着汽车工业的发展,在铸造生产方面,要求使用机械化设备,大批量生产高质量的铸件。为此,于1970年建成了以自动高压造型机为中心的汽缸体铸造车间,并于同年7月正式投产。 1.车间概况该公司是生产4～10吨級汽车的。原来铸造汽缸体铸件使用拋砂机造型,不能满足要求。为提高生产率,增添新设备,要求:(1)适应多品种生产,通用性好;(2)铸件壁薄,质量高;(3)降低劳动强度;(4)改善工厂环境。为此,确定使用具有一定通用性的专用设备,生产节拍为2分钟。为了适应每小时铸造
With the development of automobile industry, in the casting production, require the use of mechanized equipment, mass production of high-quality castings. To this end, in 1970 built a high-pressure automatic molding machine-centered cylinder block foundry workshop, and in July the same year formally put into operation. 1. Workshop Overview The company is producing 4 to 10 tons of cars. The original cast cylinder block casting sand casting machine shape, can not meet the requirements. To improve productivity and add new equipment, the requirements are: (1) adapt to multi-species production, good versatility; (2) cast thin wall, high quality; (3) reduce labor intensity; (4) improve the factory environment. To this end, to determine the use of a certain general availability of special equipment, the production beats 2 minutes. In order to adapt to hourly casting
