Roll Hemming Sheet Metal

Hemming processes press hemming.

Roll hemming sheet metal.

Hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. 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. Conventional die hemming and roll hemming. In sheet metal hemming means to fold the metal back on itself.

Sheet metal hemming process can be generally classified into two major categories such as classical conventional hemming and roller hemming process. The process uses traditional hydraulically operated stamping presses to hem closure parts and being the last forming process in stamping it largely determines the external quality of such automotive parts as doors hood and trunk lid. There are two types of hemming operations. Hemming is used in the sheet metal forming industry.

Hems are commonly used to reinforce an edge hide burrs and rough edges and improve appearance. 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. Create a bend with acute angle tooling in the metal 30 is preferable but 45 will work for some circumstances.
