Applications in steel construction
The automatic hydraulic hold-down, Kenn-Nr. 549, clamps the workpiece onto the support during the punching or shearing operation. It presses the material firmly down before the tool stroke, so that it is not pulled up or displaced when the punch enters.
Typical applications
- Holding sections and plates in place during punching
- Preventing the material from being dragged up on the return stroke of the punch
- Securing the workpiece position during shearing
- Clean hole pattern through slip-proof clamping
- Increased working safety during repeated fabrication
Which businesses use it
Used in structural steelwork, metalworking and locksmithing, in shops that process structural steel and plates on punching machines and combination shears.
Frequently asked questions
Why does a punching machine need a hold-down?
On the return stroke of the punch, the material tends to be pulled up with it. The hydraulic hold-down presses the workpiece firmly down before the stroke and keeps it in position throughout the operation, ensuring a clean hole pattern and safer handling.
What does automatic hydraulic mean in this context?
The hold-down is hydraulically driven and closes automatically in time with the machine cycle, in sync with the tool stroke. The operator does not have to clamp the workpiece by hand.
