Are the holes in the tray drilled or punched?
Thread Content
As the title suggests, are the holes in the tray drilled using a drill machine or punched using a punching machine?
Thin sheets are all stamped out; a regular stamping machine is sufficient. It is suitable for industrial operation; the plates used for drilling are those that have been subjected to comparison. The thickness of the tray plates is generally below 3 mm, with some carbon steel trays having a thickness of 4–5 mm, but in all cases these trays have holes punched in them.
Most are stamped using a punch press, and then welded together to form a plate.
There are many manufacturers of tower internals in Honghu; they mostly use punching techniques, and many of them already employ CNC punching machines, which enable fast and precise work
Punched out by a punch press, mass-produced
How do I perform punching? The more specific, the better
Our factory emerged through rapid development, because of the speed at which it progressed
One should ask how to use the punch press~~~ It might be difficult to explain if one has no practical experience with it.
What I know is that the holes in thin tray plates are all cut using lasers
Most of them rushed out. Thicker ones use drills.
I visited a tower internals manufacturing plant, and I saw that the parts are produced using punching machines; this method allows for fast processing. With CNC punching machines, the error in the distance between adjacent holes can be kept within 0.05 mm, which is much less than the standard value of 2 mm. If there is a large quantity of tower plates of the same specifications, CNC punching machines can produce more than 2 tons of such plates per day. The punching quality is ensured by the gap between the upper and lower dies; generally, a precision gap of less than 15% of the plate thickness is sufficient.
It’s usually pushed out; there are so many holes in a single plate, and drilling would require too much labor
There’s no dispute about this; they all rushed out. Today’s punching machines are all automated; both the sieve plates and floating valves are punched.
Punching can improve efficiency and ensure precision; drilling is too labor-intensive, and it’s difficult to maintain consistent dimensions
The sieve holes are all punched using CNC punching machines, which ensures high efficiency; however, the diameter of the holes should generally be ≥ the thickness of the plate. It is relatively more difficult to punch holes in stainless steel plates.
Metals can be stamped, while non-metals can only be drilled. For FRP work, we carry out drilling, or use engraving machines and hole-opening tools
One year, someone asked the manufacturer, Zhengyuan Company, why the holes on the trays were so round, and they said they were made using a laser.
