The Thermoset Extrusion Technology for Processing Farm Steel Forks and the Design of the Nesessary Machinery

The technology in use for processing farm steel forks is examined and its deficiency pointed out . A new thermoset extrusion technology for processing steel forks is developed and the essential processing tool, the radial pulse extrusion head, is designed and fabricated. The questions must be considered in developing the plan design and the structure design of the four spindle extrusion press for machining the four teeth steel fork tip are explained and discussed. Conclusions about the works quality, the production efficiency, the economic benifit, the social benifit and the application of this technical achievement are described at the end of this article.
