ONE-TRANSFER STAMP-DRAWING OF CYLINDRICAL PARTS,
Abstract
An explosive single transfer metal forming technique for the manufacture of small- and medium-sized cylindrical parts is described. A schematic of the stamping press is presented. The press was used to manufacture parts from sheet metals A1M, A2M, L62M, and 08kp. A photograph of the stamped objects is presented. The quality of the finished product and the limiting tensile strength coefficient of the metal were determined as functions of the die stamp plunger curvature, of the nature of lubricant, and of the method of die lubrication. A one-sided die lubrication was found to give best results with objects made from brass and soft steel, using machine or transformer oil or any other oil. In the case of aluminum objects, best results were obtained by using machine oil type lubricants and, for stamping shallow parts, by using copious amounts of lubricants (transformer oil is prefereed to machine oil). It is concluded that this stamping procedure is as efficient as press stamping. (Author)
