Study on Production of Rubber Sealing Strips with Steel Bones

Rubber sealing strips with steel bones are used in car manufacturing that produced in large quantities. Cutting processes, such as milling and punching, are needed when the strips are produced. Accuracy, smoothness and flatness of the machined surface have to be guaranteed in the cutting process; moreover, deformation of the steel bone and peeling-off of the rubber must be avoided. Therefore cutting action of rubber/steel strips differs from that of rubber or metal workpiece separately. In this paper, milling and punching of rubber/steel strips were studied with the aim to increase the part quality of a production line for sealing strips of cars. Suitable cutting tools and fixtures are both necessary for cutting of the strips. The teeth of the milling saw should be made knife-edged and the cutting edge of the punching tool be inclined. Fixtures should be used to sustain the workpiece and resist deformation. By using of suitable tools and fixtures, high quality of rubber/steel sealing strips is achieved in the production line.
