Roll Hemming Sheet Metal

Create a bend with acute angle tooling in the metal 30 is preferable but 45 will work for some circumstances.

Roll hemming sheet metal.

Hemming is used in the sheet metal forming industry. Hemming presses are widely used in automotive manufacturing for hemming of sheet metal body components. Hems are commonly used to reinforce an edge hide burrs and rough edges and improve appearance. Roller hemming combines standard industrial robots equipped with a standard roller hemming head that follows the contour of the outer flanges of a sheet metal component optimally hemming it over an inner panel which is precisely nested in a die.

When working with a brake press hems are always created in a two step process. 1 depicts three different steps of conventional sheet hemming in which an inner sheet is placed over outer sheet and with help of punch outer sheet is bent to form hem with the help of rigid. Hemming processes press hemming. Sheet metal hemming process can be generally classified into two major categories such as classical conventional hemming and roller hemming process.

Hemming is the process in which the edge is rolled flush to itself while a seam joins the edges of two materials. In sheet metal hemming means to fold the metal back on itself. Conventional die hemming and roll hemming.
