Design and automation of crimping machine for jato nozzle

Abstract

Press working is the probably the earliest occupation known to mankind. Native metals have been formed technological and shaped 7000 years ago. Press working industry utilize million on man, production tool, forming processes, building and other related facilities, in order to form and produce the material to meet the increased demand of mankind. The high productivity of forming process, the simplicity of press operation, all leads to greater extension of this method manufacturing. Of course, the many alternative processes require the complementary tooling, while in the metal forming dies or press tools the trouble has often been traced to an adequate grasp of the basis of design construction. Press tools and metal forming processes in which they are used in an inadequate grasp on the basis of design and construction are greatly improved of lathe both in design and in regards to capacity. Press working may be defined as the chip less mfg. process by which various components are made from sheet metal. These process is also termed as cold stamping. The machine used for press working is called press. The sheet metal operation done on press be grouped into two categories : i ) Cutting Operation and ii ) Forming Operation. In cutting operation, the w/p is stressed beyond it’s ultimate strength. The stresses caused in metal by the applied force will be shearing stress. In forming operation, the stresses are below the ultimate strength of the metal. In this operation, there is no cutting of the metal but only the contour of the w/p is changed to get the desired product. Keywords: Press working
