Design and construction of an efficient bench vise for mechanical manufacturing processes

Abstract

The present paper consists of designing and manufacturing an efficient bench vise as a means of clamping for mechanical manufacturing processes, evaluating its technical feasibility for production in a workshop with machine tools such as lathe, milling machine, drilling machine and press; A technical study of structural design was carried out using ISO manufacturing standards with materials in supply status offered by the local market such as ASTM A36 4mm hot rolled steel sheet, UPN 80, ASTM A536 nodular cast iron, AISI 1018 steel, AISI steel 1045, assembled with SMAW welding and screws. With the general objective of designing a solution that reduces production times to the maximum and optimizes manufacturing through machining processes with and without chip removal, that meets the technical characteristics of quality and guarantee for the end user, it can be installed simple way in the same workshops where they were built; checking the design results through analysis with computational tools. The process in general will end by checking the functionality of the device when it is subjected to a yield stress and the means of fastening to the limit of its capacity; in order to offer a result that translates into verified mechanical resistance data that will have the function of providing operating data. The research was carried out through a field analysis to demonstrate the capacity of the clamping tool found in the national market, and compare it with the one manufactured in this proposal. At the end of the project, it is functionally operational; responding to tests of torque, force, parallelism of the jaws, rapid movement of the mobile jaw and perpendicularity of the clamped elements.
