As Sheet Metal Stock Thickness Increases The Clearance Between Punch And Die Should
B be increased a round sheet metal slug produced in a hole punching operation will have the same diameter as.
As sheet metal stock thickness increases the clearance between punch and die should. A be decreased b be increased or c be unaffected. Next make sure you have the correct die clearance for the material type and thickness you re punching see figure 2. B a circular sheet metal slug produced in a hole punching operation will have the same diameter as a the die opening or b the punch. Increased 16 7 a circular sheet metal slug produced in a hole punching operation will have the same diameter as the a die opening or b punch.
A long time industry rule of thumb used by die makers for the clearance between the punch and the die button is 5 of the stock thickness per side. As sheet metal stock hardness increases in a blanking operation the clearance between punch and die should be a decreased b increased or c remain the same. As sheet metal stock hardness increases the clearance between punch and die should. 30 table 1 recommended die clearance table.
Generally typical values span from 3 to 8 of sheet thickness. 30 heavy duty die clearance. Min service life of dies. 16 6 as sheet metal stock hardness increases in a blanking operation the clearance between punch and die should be a decreased b increased or c remain the same.
This provided an acceptable burr height and slug control. 20 25 long service life of dies. A large factor is the type of work material and its temper. This adds stress to the sheet and increases distortion.
As sheet metal stock hardness increases in a blanking operation the clearance between punch and die should be a decreased b increased or c remain the same. The bend angle is determined by the depth that the punch forces the sheet into the die. As sheet metal stock hardness increases in a blanking operation the clearance between punch and die should be increased a circular sheet metal slug produced in a hole punching operation will have the same diameter as the. A circular sheet metal slug produced in a hole punching operation will have the same diameter as a the die opening or b the punch.
Determine the punch and die clearance by experience. If you have too much clearance the material will stretch before the material fractures to produce the slug. The greater the sheet metal thickness the higher the clearance value should be. In manufacturing industry there is a range of optimum values for specific processes clearances may span from 1 to 30 of sheet thickness.
The sheet is placed between the two and held in place by the backstop.
