30 table 1 recommended die clearance table.
As sheet metal stock thickness increases the clearance between punch and die should.
A large factor is the type of work material and its temper.
Determine the punch and die clearance by experience.
Min service life of dies.
The greater the sheet metal thickness the higher the clearance value should be.
The percentage of the die clearance to the material thickness.
In manufacturing industry there is a range of optimum values for specific processes clearances may span from 1 to 30 of sheet thickness.
This adds stress to the sheet and increases distortion.
As sheet metal stock hardness increases the clearance between punch and die should.
The bend angle is determined by the depth that the punch forces the sheet into the die.
The press brake contains an upper tool called the punch and lower tool called the die between which the sheet metal is placed.
A be decreased b be increased or c be unaffected.
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.
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.
If you have too much clearance the material will stretch before the material fractures to produce the slug.
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.
B be increased a round sheet metal slug produced in a hole punching operation will have the same diameter as.
The sheet is placed between the two and held in place by the backstop.
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.
Generally typical values span from 3 to 8 of sheet thickness.
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.
30 heavy duty die clearance.
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 depth is precisely controlled to achieve the required bend.
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.
Next make sure you have the correct die clearance for the material type and thickness you re punching see figure 2.
