A Review on “Failure Analysis of Forming Tool Breaking in Pneumatic Machine” | Forging | Mechanical Engineering

Description
In this paper, the pneumatic machine the forming tool is used to mold the powder in the die. The forming tool used in machine breaks down, due to the stroke coming from the feeder that strikes the tool at high speed. If the small bushes are molded in the die the speed of the feeder is high due to which the tool breaks down easily, while in the case of large bush the speed is bearable by the tool. This research aims to the analysis of the tool material and the force striking the tool by the feeder. The objective is to improve the fracture toughness and wear resistance of forming tool and analysis and testing of the new improved tool.

   Impact Factor Value 3.441  e-ISSN: 2456-3463  International Journal of Innovations in Engineering and Science, Vol. 2, No.7, 2017    www.ijies.net   18 A Review on “ Failure Analysis of Forming Tool Breaking in Pneumatic Machine”   Aishwarya .V.Bisne 1 , Dr. A.K.Mahalle 2 1 Student, M TECH CAD/CAM, Mechanical Engineering Department, GHRCE, Nagpur, Maharashtra, India 2  Professor, Mechanical Engineering Department, GHRCE, Nagpur, Maharashtra, India  Abstract  –    In this paper, the pneumatic machine the  forming tool is used to mold the powder in the die. The  forming tool used in machine breaks down, due to the  stroke coming from the feeder that strikes the tool at high speed. If the small bushes are molded in the die the  speed of the feeder is high due to which the tool breaks down easily, while in the case of large bush the speed is bearable by the tool. This research aims to the analysis of the tool material and the force striking the tool by the  feeder. The objective is to improve the fracture toughness and wear resistance of forming tool and analysis and testing of the new improved tool.  Keywords-    pneumatic machine, forming tool, die,  powder, etc   INTRODUCTION I n this industry based project related to forming tool  breaking in the pneumatic machine for MM sintered  products PVT LTD. MIDC Nagpur. MM sintered is Assigned a work for designing the bush bearing by the molding process in the pneumatic machine and hydraulic machine which is used for pressing or molding and forming the powder used to make the bush bearing. During the visit, the problem was discussed The forming tool used for pressing the powder in the die breaks down, due to the stroke coming from the feeder that strikes the tool at high speed. The upper die of forming tool is exposed to shock like compressive and bending loads. The life of tool is less than one month.During this project, various causes of tool failure will be identified and rectified by using data collected from the industry. The objective is to rectify the design of tool after studying the failure parameters. II-DATA COLLECTION ã   RAW MATERIAL USED a)   Bronze Powder  b)   Iron Powder ã   Manufacturer Of Raw Material a)   Bronze Powder- PP Patel And Company Solapur  b)   Iron Powder- Hognas Limited Ahmednagar ã   Machine Used For Processing a)   Pneumatic machine- 20 Ton and 30 Ton III-METHODS USED IN PROCESSING OF PARTS ã   The standard methods of shaping metal powder for  parts production includes. 1.   Mechanical pressing 2.   Injection molding 3.   Isostatic molding ã   Most of the parts are made my mechanical pressing and sintering. Parts can be small to moderate in size and simple or complexed. ã   Parts produced by mechanical pressing have close tolerances .   1.   Failure Data Collection    Reasons for Breaking of Tool ã   The forming tool used for pressing the powder in the die breaks down, due to the stroke coming from the feeder that strikes the tool at high speed. ã   If the small bushes are formed in the die the speed of the feeder or frequency is high due to which the tool breaks down easily. ã   While in the case of large bush the speed is bearable  by the tool.   Impact Factor Value 3.441  e-ISSN: 2456-3463  International Journal of Innovations in Engineering and Science, Vol. 2, No.7, 2017    www.ijies.net   19 ã   The upper die of forming tool is exposed to shock like compressive and bending loads. The cutting and the lateral area is affected by wear strain as a result of friction between the workpiece and the tool. Fig (a)- FORGING PRESS Fig(b)- BROKEN TOOL 2.   OBJECTIVE ã   To increase the strength of material. ã   To design a tool by using the different material. ã   To analyze and redesign a tool which is subjected to frequent breakage and heavy impact force . 3.   ASSEMBLY OF THE ENTIRE SYSTEM Fig(c)- DIE Fig(d)-UPPER AND LOWER TOOL Fig(E)-ROD USED FOR INNER DIAMETER OF BUSHES 4.   LITERATURE REVIEW Prof. Dr.-Ing.E.h.F.Klocke Methods of modifying the subsurface layer selectively Subsurface hardness In this process, only one subsurface with a certain thickness (up to a maximum of 5 mm) is hardened selectively. Hardness values of up to 66 HRC are achieved.Depending on the carbon content of the material and on the depth of the hardening process. The material can be heated by induction, conduction, flame, electron beam or laser. Associate Professor Mechanical Engineering, MGM’S JNEC Aurangabad The objective of this paper is to improve the availability of forging press. For this work, different quality tools are used to analyze the cause of failure, and corrective actions are taken as required.   K. Nagendra’s, S. Sathisha and J.

The results shows the Stress level in the HCHCR is comparatively low then the Tungsten Carbide die, means the Tungsten carbide can withstand more stress load for the Blanking Operation in industry SANAP ASHOK B1, DOLAS .D.R2 1M.E. Manufacturing, MGM’S JNEC Aurangabad Associate Professor Mechanical Engineering, MGM’S JNEC Aurangabad This paper has been carried out on 1000 ton Pneumatic Forging press performance analysis. The critical system & critical parts are identifying by using Pareto chart, which has been under breakdown condition is also identified and analyzed. Cassio Barbosa . Ibrahim de Cerqueira Abud .

In general tool, steels are high carbon and high alloyed steels designed for reaching elevated levels of mechanical strength, sufficient for the type of loading. Defects on the surface of this material can lead to stress concentration J.Arun1S.PravinKumar2,M. Venkatesh3, A.S.Giridharan4 1UG Graduate, Department of Mechanical Engineering, Government College of Technology, Coimbatore. Failure Mode and Effect Analysis is done in the process of Punching. A punching operation is done on various workpieces, and the defects are found. These steels are classified in different groups, according to their chemical composition and mechanical properties. Ullash Joshi1 Dr. Balasaheb D. Biranale2 Antriksh Bhatt3 1P.G.Student 2Principal 3Assistant Professor Punching or piercing is the oldest and most frequently used sheet metal forming process. Piercing process is used for the finite element method to reduce the failure of punch for a sheet material. 5. PROBLEM DEFINITION The forming tool of the pneumatic system breaks down  prematurely due to the stroke coming from the feeder 8the life of the tool is less than one month because of this the redesign of the tool causes high cost and the ideal time increases. 5.   RESEARCH METHODOLOGY In the present study, we create the CAD model of tool. Then analysis of design will be performed. Then the modifications and analysis of modified design and the stress analysis will be performed. CONCLUSION The aim is to investigate various reasons for the failure of forming tool. A brief review of forming tool analysis different conventional and recent techniques was discussed for various types of tool. ã Failure types in the most of the form ing tool  break down, due to the stroke coming from the feeder that strikes the tool at high speed. ã The upper die of forming tool is exposed to shock like compressive and bending loads.
