Piercing of all the holes is best done together to ensure good hole-to-hole tolerance and part repeatability. However if the material distorts, the method described below can be done. When there are large numbers of holes, in a tight pitch, there could be distortions, due to the high amount of tension on the upper surface due to stretching and .Semi Tubular self-piercing rivets can be used with materials such as leather, some plastics, and light sheet metals. When piercing sheet metal, adjustments may be suggested to the rivet raw material, hole diameter and heat treatment. Self- piercing rivets can be used especially in difficult spot welding applications, piercing and fastening in . Blanking. The term blanking can be somewhat confusing, because it has more than one definition. The blank is defined as the flat piece of sheet metal that eventually turns into the finished piece part.. Blanking is a method in which the sheet metal is cut and the slug is saved for further pressworking. The size and the shape of the blank are proportional to the size and . This document discusses sheet metal cutting operations.

This procedure is likely used for the further processing of semi-finished products made of sheet metal, partially-finished parts in the automobile industry or plastic parts in the white goods industry. . The required die clearance depends on the shear strength and the thickness of the sheet. In the TOX®-Piercing Systems brochure, a table .Set sheet metal grommets quickly and efficiently with Micron’s industrial die sets. These dies do the same job as a 4 piece set by combining features from the cutter and setting dies. The die first punches the hole in the material on the first pass, then sets the grommet on the second pass. This eliminates the need to swap dies or run concurrent machines. √ The top shaft of our dies is 1/4 .This procedure is likely used for the further processing of semi-finished products made of sheet metal, partially-finished parts in the automobile industry or plastic parts in the white goods industry. .

Mild steel sheet. 18 or 20 or 22 gauge. About $30 for a 4'*4' piece. 22 gauge for new Hondas. 18 for old vw pans. 20 gauge for old vw bodies. It's a personal preference. 22 is way easier to bend than 18, but 18 will take more weld without blowing through. The stuff I get is light gray with an oil film, but black steel would work too.
