Hydraulic Jack operated Hose Crimping Machine

Abstract

The present paper deals with developing of a crimping machine that can crimp hydraulic hoses with its fitting without the use of electricity. Detailed literature review indicates the fabrication of crimping machine that operates with electricity that inspired the authors to develop a hydraulic crimping machine that works without electrical power. Such a crimping machine is very useful when the rig is in movement and suitable for emergency crimping work in order to avoid shutdown time.The author has used Autodesk inventor software for designing critical components of the machine and obtained safety factor more than one for all the critical components. Safety factor less than one leads to the unsafe working condition of the critical parts. Fabrication of the whole assembly has been completed successfully for the required crimping for a hose size of 19.05 mm. The crimping machine has been tested successfully for crimping the required hose size. The design of the machine can be altered so that it can accommodate different die sizes in order to crimp hoses of different sizes.
