Cooler production process to make cooler for fuel involves lining up end surfaces, inserting at least one punch in channel, stamping and removing punch

摘要

The cooler production process produces a cooler with a base body (1), outer walls (5) and channels (3) bounded by webs (4), and closing elements (7, 9) on the ends of the base body, with at least one connector (8). It involves lining up the end surfaces (6) of the body, inserting at least one punch in a channel, stamping, cutting out a stamping residue, and moving punch perpendicular to the insertion direction before removing the punch from the channel and ejecting the residue.
