Applications in steel construction
The hydraulic punching machine Hydraulic 1250 creates holes in structural steel and plate by shearing with punch and die. The hydraulic drive applies the punching force evenly, making it suitable for thicker materials and larger hole diameters as well. This allows hole patterns for bolted connections to be set in a single stroke without marking out and drilling.
Typical applications
- Punching structural steel, angle steel and flat steel for bolted connections
- Setting hole patterns in gusset plates and connection parts
- Openings in the webs and flanges of sections
- Repeating perforations in the series production of steel components
- Working holes prior to bolting or riveting
Which businesses use it
Used in steel and metal fabrication, in locksmith shops and steel-fabrication businesses that work structural steel with hole patterns for bolted connections.
Frequently asked questions
What is a punching machine used for in steel fabrication?
The punching machine creates holes in structural and flat steel by pressing a punch into the material against a die and shearing it. This produces hole patterns for bolted and riveted connections without marking out and drilling, which speeds up cutting and processing.
What advantage does the hydraulic drive offer?
The hydraulic drive applies the punching force evenly and in a controlled manner. This permits the punching of thicker materials and larger diameters with a clean hole pattern and consistent quality over many strokes.
