How To Twist Sheet Metal To Form An Auger Shape

Hi randy yeah it s exactly what i m talking about as you said we can do it in section for example my screw conveyor has a 9 outside diameter around a tube of 2 1 2 sch 40 with a 9 pitch we use to cut many item of a circular shape who looks like a donut of approximately one pitch each in a sheet metal then we weld them together after.

How to twist sheet metal to form an auger shape.

Maziar ramezani zaidi m. If your sheet metal is long ask a friend to stabilize the part hanging out from the form blocks so it doesn t affect the bend. Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. Next put your wooden or metal form blocks in the vice and clamp your sheet of metal between the forms.

This video describes how to use twist feature in solidworks. To bend sheet metal in a vice start by marking a line on the metal where you want to bend it. Many small companies are required to manufacture curved products and shallow parts with fine details in a small lot size which leads to both a higher production cost per detail and a need for multiple tools. I think an auger screw is going to fall into the second category.

Other shapes such as a sphere will require actually stretching or compressing the plate in areas to form the shape. The feature is limited to only 2 profiles and no guide curves so look for opportunities to put most of the complexity into the profiles. Most highly complex shapes that are actually formed out of sheet metal can be created using lofted bends but often the trick to creating the shape lies in what you use for the profiles.

You won t know the exact shape to cut without some trial and error and it would depend on the forming process as well. Sheet metal forming is a costly manufacturing process that is widely used in different industries. The applied force stresses the metal beyond its yield strength causing the material to plastically deform but not to fail. By doing so the sheet can be bent or stretched into a variety of complex shapes.
