Formation Sealing Technology for the Bolt Hole of Injector Pressure Plate
Wang Liping;FAW Jie Fang Automotive Co., Ltd.,Wuxi Diesel Engine Works;
The formation sealing technology is a new drawing and expanding technique, with the theory is roughness of action. This paper is mainly describes the technics applying on the inside of bolt hole of injector pressure plate which is made of Compacted Graphite Iron. Under the analysis of technical requirements and working condition, research on the high-intensity compacted graphite iron machining,and select applicable tool structure and machining parameters for achieving wall roughness and circularity requirements in the specifications. The technics needs a little installing space during sealing,and realizing quick assembling via hand tool. It is also applicable for batch production. Skills required for workers are low and the feasibility of plugging technology is verified through trial manufacture..
