Feb 01,2013&0183;For 1000 strike punching of an ultra-high strength steel sheet having a tensile strength of 1200 MPa,a sheared edge of high quality was produced with a TiAlN-coated punch having the small round edge.In addition,the chipping of the punch edge was prevented even for a slight clearance by the small round edge.May 28,2020&0183;Punching thick material typically means running at higher-than-ideal tonnage,and a dull tool only will increase that tonnage.” Also important in extending tool life proper turret alignment and lubrication.6.Sacrifice Grind Life for Strength .Consider reducing the straight-before-radius on a punch tip,recommends Erler,as the stouter The formula is Perimeter times thickness times shear.For round holes in steel this is Diameter * PI * 30.Thirty tons being the approximate shear strength of mild steel plus an allowance for friction.Tons are used to aid in press selection and rating.The practical limit for depth of punching cold is the diameter of the hole.Stamping can be blanking,but it also includes forming,bending,flanging,hole punching processes.If the drawing process is added to the punch machine on the basis of the blanking,the press can be called hydraulic punch press.Generally speaking,the punching machine has a simple structure,fast production speed and high efficiency. - This hydraulic hole punching tool features high strength and good toughness with premium alloy steel construction.It has a flat seat,smooth and not fall.Quick to change the dies. - The heavy-duty metal hole punch tool needs to connecting with a hydraulic pump to get ideal performance.
