Forming Countersink In Sheet Metal

Automated punch presses have been punching holes in sheet metal for more than 60 years.

Forming countersink in sheet metal.

To create a flange an upper forming tool descends and presses the sheet against a lower die with a rotating v opening. The die shown at the left allows the punch and die to bottom the countersink shape into the workpiece at the bottom of the stroke due to the nature of this style material will deform and a burr will occur. 50 x 80 without repositioning. No c sink needed no metal removed from the sheet metal and more strength at the area of the screw head.

After drilling a hole in the table for the screw you will be using and the matching hole in the sheet metal use this punch to make a depression in the sheet metal so the screw head sits below the surface of the sheet metal. Before you apply forming tools to sheet metal parts in the design library you must right click the folder that contains the forming tools and select forming tools folder to designate its contents as forming tools. We recommend the major. 0 004 maximum sheet thickness.

A forming countersink tool for the punch press is made to your specifications and produces a clean countersink in seconds. Both machined and formed countersinks are available conical holes cut into a manufactured object allowing a screw nail or bolt to be inserted flush with the surface. Sheet metal fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending. The old way to make a countersink was a three step process.

Punch the hole drill the sink deburr. And when it comes to forming the opportunities abound. Designing sheet metal countersinks is easy with a little thought and guidance from this video. How many holes have they punched.

Pressure forces the die to rotate and fold the flange around the upper tool. A swiss army knife of metal fabrication the punch press now can mark deburr and form. This applies to forming tools that are part files sldprt not form tool sldftp files. Three step processes like this cost unnecessary time and money.

The flange needs to be of a certain height about 0 24 in depending on the tool to allow the rotating die to initiate the forming process. The punching and forming work center punches holes in the sheet metal stamping countersinks and profiling the parts to their finished size. The machined type of countersink is used in a or b series standard units for countersinking up to 10 gage material. Trumpf sheetmetal fabrication center.
