DESIGN AND ANALYSIS OF PROGRESSIVE TOOL FOR METAL BUCKLE CABLE CLIP

MECHANICAL ENGINEERING

Now-a-days usage of sheet metal components is growing rapidly, hence the production of the sheet metal components by using press tools were increasing day-by-day. So the maintenance of the tool becomes challenging as the matting parts such as punches and dies deforms with the increase in rate of production, and also the rate of deformation depends upon the thickness of the component that is to be produced. As the deformation increases tool should be disassemble and grinded finely, as a result punch length and die thickness decreases and hence tool life decreases. While designing and manufacturing of a press tool selection of die steel alloy is the most important factor. This paper deals in finding the best die steel alloy among M2, SKD11, D2 and HCHCr and deals in development of strip layout, design of die plate, punch holder, thrust plate, stripper plate, top and bottom bolster and calculations for cutting force, press tonnage. Analysis carried out in designing a progressive tool which perform piercing and blanking operation. The former operation is piercing and is followed by blanking. The software’s used for CAD designs are AutoCAD 2019, Catia V5r21, and analysis is done in Ansys 17.1.
