Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Jigs and Fixtures, Vol. 2: Drill Jigs These legs are round, and provided with a shoulder A, preventing them from screwing into the jig plate. A headless screw or pin through the edge of the circumference of the threads at the top pre vents the studs from becoming loose. These loose legs are usually made of machine steel or tool steel, the bottom end being hardened and then ground and lapped, so that all the four legs are of the same length. It is the practice of many tool-makers not to thread the legs into the jig body, but simply to provide a plain surface on the end of the leg, which enters into the jig plate, and is driven into place. This is much easier, and there is no reason why for almost all kinds of work, jigs provided with legs attached in this manner Should not be equally durable. Of course, when jigs are made of machine or tool steel, and legs are required, the only way to provide them is to insert loose legs. In the case of cast-iron jigs, however, solid legs cast in place are preferable. The solid legs cast in place generally have the appearance shown in Fig. 69. The two webs of the leg form a right angle; which, for all practical purposes, makes the leg fully as strong as if it were made solid, as indicated by the dotted line in the upper View. The side of the leg is tapered 15 degrees, as a rule, as shown in the engraving, but this may be varied according to conditions. The thickness of the leg varies according to the size of the jig, the weight of the work, and the pressure of the cutting tools, and depends also upon the length of the leg. The length b on top is generally made times a. As an indication of the size of the legs required, it may be said that for smaller jigs, up to jigs with a face area of 6 square inches, the dimen sion a may be made from to inch; for medium sized jigs, lye to inch; for larger sized jigs, $4 to inch' but of course, these dimensions are simply indications of the required dimensions. As to the length of the legs, the governing condition, evidently, is that they must be long enough to reach below the lowest part of the work and the clamping arrangement.

Download or read book Plastics Technology Handbook Volume 2 written by Don Rosato and published by Momentum Press. This book was released on 2011-10-13 with total page 1024 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive handbook provides a simplified, practical and innovative approach to understanding the design and manufacture of plastic products. It will expand the reader's understanding of plastics technology by defining and focusing on past, current, and future technical trends. The content is presented so that both technical and nontechnical readers can understand the interrelationships of materials to processes. Different plastic products are examined and their related critical factors are shown, from meeting performance requirements in different environments, to reducing costs and targeting for zero defects. Examples used include small to large, and simple to complex shapes. Information is included on static properties (tensile, flexural), dynamic properties (creep, fatigue, impact) and physical and chemical properties. Extensive reference sources and useful data and physical and chemical constants are also provided. Volume 2 offers detailed coverage of most major plastics processing techniques, including injection molding, extrusion, blow molding, and thermoforming.

Download or read book Design of Jigs Fixtures and Press Tools written by K. Venkataraman and published by Springer Nature. This book was released on 2021-07-26 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook is aimed at providing an introduction to the subject for undergraduate students studying mechanical and manufacturing engineering at most universities. Many of the universities prescribe a syllabus that contains both Design of Jigs and Fixtures, and Design of Press Tools in a single semester course. Keeping the above in mind, this book is designed in two parts. Part-I deals with Jigs and Fixtures and Part-II is earmarked exclusively for the study of Press Tools. Both these subjects are built progressively in successive chapters. A separate appendix, in each part, provides short answer questions with answers, which will help the students in clarifying doubts and strengthen their knowledge. The explanatory notes and illustrations provided in the book will serve as an aid for learning. End-of-chapter questions and answers will prove useful for self study. This textbook will be extremely useful for the students and practicing engineers studying mechanical, manufacturing, and production engineering.
