Bending Stainless Steel Sheet Metal
0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance keep in mind that some metals are more brittle than others.
Bending stainless steel sheet metal. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Stainless steel 1 20 ga. Bend radii minimum bend sizes. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick.
A cutout or the edge of your flange to your bend. How to bend sheet metal without a brake. The slack between the wipe die and the punch plays an important role in getting a good result. Scoring and bending.
Mild steel 2 12 ga. Push the clamping leaf handles away from you to raise the clamping leaf. As a result the wipe die also determines the bend s inner radius. Making the bend with a sheet metal brake.
Determine your minimum bend by measuring the distance from your closest feature i e. Stainless steel 1 14 ga. Mild steel 1 16 ga. 4 due to the high hardness of stainless steel plate with obvious cold work hardening effect therefore the tool steel should be chosen as the punch die and the heat treatment hardness of.
Choose a bend radius that matches your minimum bend. And not only for its aesthetic function but also for regulations especially in the food sector since when bending a stainless steel sheet even if it has protection if it is marked it not only causes an aesthetic deterioration but also causes a contamination of the bended stainless steel since the ferric particles adhered to the die pass to the bended stainless steel being very deep and sometimes even after a polishing operation of the sheet these particles remain in the stainless. Wipe bending or edge bending is another way to bend sheet metal edges. It is important to make sure that the sheet is properly pushed onto the wipe die.
When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Mild steel 1 brake shear slip roll 1 metal forming 1. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. Measure and mark the bend location along one edge of the stainless steel sheet with the tape measure.
2 the stainless steel sheet has a strong rebound tendency compared with carbon steel when bending. 3 the percentage of elongation of stainless steel plate is lower than the carbon steel the bending angle of the workpiece r is larger than that of carbon steel or there is the possibility of cracks. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. If you re bending 0 020 thick material use a 0 020 radius.
Likewise when you are trying to develop a flat pattern you will have to make a deduction from your desired part size to get the correct flat size.
