Hydraulic Press Brake Machine Manufacturer in India

Hydraulic press brake machine for workshops and fabricators

A hydraulic press brake machine uses oil pressure in two cylinders to drive the ram. Compared with older mechanical (flywheel) press brakes, the hydraulic drive gives full force at any point of the stroke, lets the operator stop the ram instantly, and protects the machine from overload through a relief valve. That makes it the most common press brake type in Indian fabrication shops.

Devraj Engineering's PBR series covers the 20 to 40 tonne range. These machines are built for workshops, panel makers and job shops that bend thin to medium sheet every day and want a machine that is simple to run and maintain. As hydraulic press brake machine manufacturers in India since 1971, we build these machines at our Ahmedabad works and supply them across the country.

PBR hydraulic press brake specifications

Need more force or length? The CNC press brake range starts at 40 T / 1600 mm and goes up to 250 T, and heavy duty models go to 400 T. Hydraulic machines with PLC or NC control are described on the PLC press brake page.

How the hydraulic press brake works

1. Positioning. The operator places the sheet on the lower die and against the back gauge stops.
2. Approach. On pressing the foot pedal, the ram moves down quickly until the punch is just above the sheet.
3. Pressing. The ram slows to pressing speed and the hydraulic cylinders push the punch into the sheet to form the bend.
4. Return. At the set depth, the ram reverses and returns to the top, ready for the next bend.

The inch, single and continuous cycle modes let the operator inch the ram for set-up, run one stroke per pedal press for normal work, or run continuously for simple repetitive jobs.

Key features

• Inch, single and continuous cycles so the operator can choose the mode that suits set-up, trial bends or batch production.
• Full powered stroke, making the machine suitable for general sheet metal press work and not only air bending.
• Three ram speeds that reduce idle travel time and improve output per shift.
• Instant ram stoppage, which helps prevent accidents and rejected parts.
• Quiet operation with low impact loads on tools and foundations.
• Lower power consumption and low wear and maintenance, which keep running costs and downtime down.

What you can bend on a 20-40 T hydraulic press brake

As a rule of thumb for air bending mild steel with a V-die eight times the thickness, a 1 mm sheet needs about 8 T per metre, 2 mm needs about 16 T per metre and 3 mm needs about 24 T per metre. So:

• A PBR 215 (20 T, 1500 mm) suits light-gauge work such as 1-1.5 mm panels and brackets.
• A PBR 320 (30 T, 2000 mm) handles 2 mm mild steel over most of its length.
• A PBR 420 (40 T, 2000 mm) is the choice when you bend 2 mm over the full length or shorter 3 mm parts.

These are estimates. Stainless steel needs about 50% more force. Use the tonnage calculator for your own figures, or ask us to check your part.

Who buys our hydraulic press brakes

Buying considerations

• Thickest and longest bend: decides tonnage and working length.
• Throat depth: the PBR 215 has 100 mm, the PBR 320 and 420 have 200 mm. A deeper throat is needed for wide flanges and box-type parts.
• Open height and stroke: deep boxes and tall tooling need more daylight.
• Tooling: standard punch and V-die sets cover most work; gooseneck punches and multi-V dies add flexibility.
• Back gauge: manual or motorised. Ask us which suits your batch sizes.
