  • Optimization of Mechanical Crimping to Assemble Tubular Components

Worrell b a ERC for Net Shape Manufacturing, The Ohio State University, 339 Baker Systems, 1971 Neil Avenue, Columbus, OH 43210, USA b Science and Technology Group, Alliant Ammunition and Powder Company, Radford Army Ammunition Plant, Route 114, P.O. Box 1, Radford, VA 24141-0096, USA Abstract The crimping process is used often in the assembly of tubular components. In this study, with the aid of the finite-element method (FEM), the mechanical crimping operation was evaluated and optimized for a specific application. The effect of various process variables, such as the geometry, alignment and stroke of the crimper and the friction at the crimper–tube interface were investigated. Thus, it was possible to optimize the process so that the effect of springback could be reduced and the assembly quality, as indicated by the pullout force, could be improved. The crimping process of a single-grooved rod with a tube was evaluated as a case study. Based on the FE simulations, it was possible to determine the optimum alignment and the optimum design for two types of crimper geometries. © 2003 Elsevier B.V. All rights reserved.

    Layout Drafting & Pattern Making for Insulators _________________________________ LAYOUT DRAFTING & PATTERN MAKING FOR HEAT & FROST INSULATORS Hans Siebert APPRENTICE WORK BOOK & JOURNEYMAN REVIEW MANUAL Hans Siebert-2000 _________________________________ Page 1 Layout Drafting & Pattern Making for Insulators Preface This book has been prepared as a text for use in Heat and Frost Insulator apprenticeship classes. It explains basic methods of drawing patterns for developing sheet metal and other types of protective covers commonly produced for wrap over insulation. The book does not attempt to teach field work-practices or any application methods used in the trade. Learning how to crimp, bead, seam, rivet and apply materials is best accomplished on the job, not from studying a book. However, for the limited purpose of pattern development, this book meets every requirement of an apprenticeship textbook and is, in addition, also well adapted for reference use by journeymen, foremen, and pre-fabrication workers engaged in the designing and/or laying out patterns. The instructions are easy to follow with numerous practical problems that can be completed straightforwardly and worked without elaborate collections of tools or equipment. The subject-matter deals with common trade problems and the specific methods of presenting the assignments are the result of many years of teaching in apprenticeship classes as well as practical experience gained in the asbestos worker trade. The format of the book assumes sequential completion of tasks, especially regarding the preparatory work of practicing drawing principles. For the novice, later work in the book assumes knowledge gained in prior effort. For students with prior knowledge many of the projects can be completed without a drawn-out effort on the study of groundwork.

  • Effects of As Cast Holes on Cooling Patterns in Directional Solidification
    Materials Transactions, Vol. 58, No. 3 (2017) pp. 471 to 478 ©2017 Japan Foundry Engineering Society Effects of As Cast Holes on Cooling Patterns in Directional Solidication of Plate Castings Ikuzo Goto* and Setsuo Aso Department of Materials Science, Graduate School of Engineering Science, Akita University, Akita 010–8502, Japan The directional solidication characteristics and generation patterns of isolated pools of liquid metal in plate castings with as cast holes were numerically examined, and fundamental concepts for the casting design, including the holes, were also investigated. For the as cast hole effects H/T (H: as cast hole effective range, T: plate thickness), there were differences depending on the hole size as well as the casting and mold materials, which reect the directional solidication characteristics associated with the cooling effects due to the hole. For the nite-width plate castings with as cast holes, isolated liquid pools occurred at locations between a hole and an end face or between the holes under specic con- ditions. The generation status of isolated liquid pools indicated that the conditions with larger values of the difference between the end and as cast hole effects (E−H)/T (E: end-effective range) in the range of 1.8–5.3 are preferable for preventing the generation of isolated liquid pools. Therefore, the consideration of (E−H)/T is useful for the casting design. In addition, the generation of isolated liquid pools could be prevented by the appropriate use of chills. Moreover, the generation was sometimes prevented by a temperature decrease of the melt during mold lling.

  • Banker Offers Industr Specifie the Lar Selecti Highest Woven & Metal M
    BANKER WIRE OFFERS Established by Charles Banker in 1896 as C.I. Banker Wire & Iron Works, the company flourished in Milwaukee as one of many early metal fabricators making use of the new engineering marvel - inexpensive steel. Banker Wire specialized in fabricating wrought I N D U S T R I A L iron and wire products such as fire escapes, tool room partitions and bank teller cages. Changing times and changing owners gradually took its toll, and by the mid 1960’s, the company had withered to a local buyer and seller of industrial wire cloth. SPECIFIERS New ownership in 1965 gradually began revitalizing Banker. By the mid 1970’s, the busi- ness was beginning to transition from a reselling operation into a manufacturer. Over the next 30 years an evolutionary process occurred as the owners, who are also engineers and fabricators, developed new processes and designed new equipment that resulted THE LARGEST in heightened efficiency and more perfect products. Unfettered by the inefficient pro- cedures utilized by more established weavers, Banker emerged as the expert source for woven wire cloth, for both industrial and architectural applications. SELECTION OF Today, Banker is the premier manufacturer of Pre-crimped Woven and Welded wire fab- rics in North America. Our facility is the most modern and productive mill in the country, and we continue to grow and evolve.
