N2 - The traditional manufacturing method of a lead batteries tubular plate is casting. To improve the tubular plate quality, to reduce production cost, to protect environment and human health in production a new manufacturing method is needed. The task of this thesis is to analyse the feasibility of using cold extrusion by laboratory tests and application trials. A series of compression tests were performed to measure flow stress of lead and lead-antimony alloy (Sb 3.5%) at different temperatures. According to the test results, cold extrusion dies were designed. On the basis of products quality analysis and laboratory tests using cold extrusion, the manufacturing processes die-casting and cold extrusion were compared and evaluated. Based on our study, cold extrusion is proved to be suitable for production of battery tubular plate. Further suggestions of modification of production process using cold extrusion are presented.
