This document summarizes a presentation about a summer internship at Jai Bharat Maruti Limited in Pantnagar, Uttarakhand. It discusses a project to increase production at the press shop by gang pressing, which involves mounting two similar dies on a single press machine. This allows the pressing operation to be performed faster, increasing productivity. Calculations show that gang pressing can reduce processing costs from Rs. 1320 to Rs. 640 for the example part described, a gusset head used in Bajaj bikes. The advantages of gang pressing are listed as cost saving, time saving, less manpower and machine requirements, and increased production rates.

- 1. PRESENTATION ON SUMMER INTERNSHIP AT JAI BHARAT MARUTI LIMITED PANTNAGAR UTTRAKHAND BY MOHIT KESHAV R880211030
- 2. JBM AT A GLANCE
- 3. INTRODUCTION TO THE COMPANY COMPANY PROFILE Name: JAY BHARAT MARUTI LTD. Division: NEEL METAL PRODUCTS LIMITED Head Quarters: DELHI Established: 1983 Turnover: Rs.4500 Crores(overall) Employees (No.): AROUND 15,000
- 4. MISSION TO MAKE JBM A SYNONYM FOR WORLD CLASS ORGNISATION EXCELLENCE IN SHEET METAL TECHNOLOGIES VISION EXPANDING LEADERSHIP IN OUR BUSINESS THROUGH PEOPLE, KEEPING PACE WITH MARKET TRENDS AND TECHNOLOGY
- 5. PRODUCT MANUFACTURED SKIN PANEL BODY IN WHITE PARTS CHASSIS & SUSPENSION PARTS WELDED ASSEMBLIES EXHAUST SYSTEMS SEAT BELTS FRONT/ REAR AXIS WHEEL RIM
- 6. PROJECT UNDERTAKEN TO INCREASE THE PRODUCTION OF PRESS SHOP WITH THE HELP OF GANGING OF DIES.
- 7. INTRODUCTION OF PROJECT Here in this project we are concentrating on only on factor i.e. Increase in productivity. Here we are using a method of ganging of dies in which two similar dies are mounted on a press machine. This help us reduction of productivity time. Which will enhance the productivity. So this method is very much effective in increase the productivity of the material. This is cost and time saving method which will help in the betterment of the industry.
- 8. EXPLAINING PROJECT WITH AN EXAMPLE PART NO.-DZ161013 PART NAME : GUSSET HEAD Gusset head is generally a BAJAJ part which are used in platina bikes. These parts gives the support to the engine.
- 9. TABLE Process Description Incoming source of variation Product characterstics Expected/actual strokes (per hour) Receiving Inspection Wrong size Wrong grade Visual defects 1.5+/-0.1 260*1250 +/-2mm Blanking Improper profile Dent/scratch Free from Burr Dent Crack 250/150 Forming Incomplete bend Scratch Crack Dislocation Free from Burr Crack Scratches 250/160 Piercing Dim us/os Hole/slot size Location Free from Burr Crack Visual defects 250/170 Bending-trimming No thinning Incomplete profile Scratch burr Free from Burr Crack Thinning 250/180
- 10. NOW IF APPLY 2 DIES IN SAME PRESS THEN THE OPERATION CAN BE PERFORMED AT FASTER RATE TO USE GANGING OF DIES THE FOLLOWING THINGS SHOULD BE TAKEN INTO CONSENDERATION Power of the press. Size of the bluster bed. Size of the dies. Shut height of the die. Shut height of the press. Tonnage required for the die.
- 11. CALCULATION :- (Cost Estimation) Procurement for the metal sheet- 45 rupees per kg Dimensions of sheet -1230x260mm Weight of on sheet- 1.020 kg Thickness of the sheets- 1.5mm Scraps cost -25 rupees per kg
- 12. Now according to table Cost estimated for blanking- 2x150=Rs300 Cost estimated for forming- 2x160=Rs320 Cost estimated for percing-2x170=Rs340 Cost estimated for bending-trimming- 2x180=Rs360 Total cost-Rs1320 This is a rough calculated cost in this hidden cost are not involved like maintainace, worker availability etc. are not included. Now if re plan our process and mount 2 dies in one press For example Blanking and forming at a time in a single press having different dies. This will save time as well as machine cost. And similarly at the same time piercing and bending trimming operation can be done. Now the calculation of cost Cost for blanking and forming-2x150=Rs300 Cost for piercing and bending-2x170=Rs340 Total cost=Rs640 This is a rough calculated cost in this hidden cost are not involved like maintainace, worker availability etc. are not included.
- 13. ADVANTAGES OF GANGING OF DIES Cost saving Time saving Man power saving Less press machine required Utility of press machine increases Pace of work is fast Production is high
- 14. DISADVANTAGES Require bigger bluster bed May require a dummy cushion when one die require cushion and other’s didn’t so dummy cushion is given to the second die in order to balance it. Tonnage of press should be greater or equal to the die required. Shut height of both the dies should be same and should be in press shut height range.
- 15. CONCLUTION This method is very much effective in increasing the production rate. This works quite efficiently. By using this method we can cover some parameter which is very much important for every industry.
