Hemming Machine For Sheet Metals

In sheet metal hemming means to fold the metal back on itself.

Hemming machine for sheet metals.

Form your hem kick and finish it to the desired shape with your brake.

When working with a brake press hems are always created in a two step process. Figure 2a shows the flat part positioned ready for the first bend. Makes beautiful closed teardrop hems. As additional expense the hem requires a unique tooling setup separate from that for 90 degree bends.

In car part production hemming is used in assembly as a secondary operation after deep drawing trimming and flanging operations to join two sheet metal parts outer and inner together. Hems are commonly used to reinforce an edge hide burrs and rough edges and improve appearance. Hem one side or both sides simultaneously. In the fab shop the hem is created with multiple bending strokes or machine cycles.

Hemming is the process in which the edge is rolled flush to itself while a seam joins the edges of two materials. Hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. Typical parts for this type of assembly are hoods doors trunk lids and fenders. The idea was conceived by the engineers at rapid shee.
