For what do you need the punching products?
Usually all
are interested what is the application for this or this technology. Let us talk
about punching… Very small explanation – punching is a process of metal
fabrication with the use of punch which goes with the necessary force inside
the part to perform the cutting. As you can understand punch has the geometry
of hole so the hole will be the same as the punch. The force to perform the
punching called punching force or necessary punching force if you want to
calculate what tonnage you need for your task.
We speak
about sheet metal punching as the main process but there are more similar
processes: tube or profile punching, structural parts punching etc. Punching is
performed for sheet metal with the use of punching press which could be general
just as the unit to perform the hit of punch and low positioning of die,
stamping press which is usually the part of forming process or coordinate
punching press – press with the table where the part of sheet metal will be
positioned where it is necessary to make the punching.
Punching
press is the most used technology for sheet metal together with laser for metal
cutting. The differences are that the punching press needs punching tool for the work and laser – not. Punching tool at
least has two main positions – punch as the tool to perform the hit and the die
on the low position to support the material at the working area. Punching is
the cheapest technology to make the holes at sheet metal.
What is it
for? It is clear that in general there no final products after punching at all.
But the punching is the main operation to get the unfolded part for future
bending. And after the bending it will be the product for lots of different
applications: electric or other equipment metal cabinets, metal furniture
units, metal boxes, safes, arms boxes, metal shelfs, panels for elevators,
architecture and design, metal doors, bar and restaurant kitchen furniture,
ovens, medical furniture etc. The other part is perforation – process with the
making of lot of same holes in the sheet. The use of them could be the
architecture panels or panels to perform the normal ventilation, for example
top panels of the subway or railroad wagons.
