Design Philosophy

Why Fast Single-Column?

The JRF combines a slim one-piece column body with the fastest approach speed in the range and output up to 40 tons — ideal when space is tight but force demand is high.

JRA Standard

External Oil Tank

Stroke

Proven two-stage with separate reservoir; larger footprint, up to 40T.

JRG Composite

Compact Integrated

Stroke

Compact body, high cycling rate, but limited to 14T output.

This Model

JRF Fast Single-Column

Stroke

Slim column body, 250-500 mm/s approach, up to 40T output.

⚡

Fastest Approach Speed

250-500 mm/s rapid approach — the fastest in the JiuRong HPC range, minimizing non-pressing cycle time.

↕

Slim Single-Column Body

One-piece integrated column design with a small footprint and clean appearance, easy to integrate into tight machine layouts.

💪

Up to 40 Tons

Widest force range in the lineup — 1-40T across 7 bore sizes from Φ63 to Φ160mm, covering light to heavy applications.

✒

Stable High Force

Hydraulic intensification delivers consistent output with ±0.20mm power-stroke repeatability.

⚙

Simple & Maintainable

Fewer external components than standard pre-press types; standard VG68 oil and accessible internals reduce maintenance.

📏

Wide Configurability

7 bore sizes, 3-5 tonnage options per bore, total strokes 50-400mm, and power strokes 5-20mm.

Force Profile

Force vs. Displacement Profile

The JRF rapid-approach phase reaches 250-500 mm/s, then switches to high-pressure boost for the final 5-20mm — fast approach plus full pressing force in a single slim unit.

0 Low Mid High Force Displacement Rapid Approach (50-400mm) Boost (5-20mm) Rapid Approach 250-500 mm/s Air-driven, low force, high speed High-Pressure Boost Hydraulic intensification up to 40T DT2 ON
Approach Force (Air) Boost Force (Hydraulic)

The single-column body integrates both phases. The approach stroke is the fastest in the range; the boost stroke delivers up to 40 tons through 5-20mm.

Air Circuit

Pneumatic Circuit Diagram

Dual solenoid valves independently control the rapid approach and boost phases.

Cycle Logic

Operation Sequence (4-Step Cycle)

Two solenoid valves coordinate the rapid approach and high-force boost in a fully automatic cycle.

1

Rapid Approach

DT1 energizes. Air pressure acts on the hydraulic oil surface, driving the piston downward at high speed through the total stroke.

DT1 ON DT2 OFF
2

Boost Stroke

The piston meets resistance. DT1 holds while DT2 energizes, activating the booster assembly for high-pressure output through the power stroke.

DT1 ON DT2 ON
3

Pressure Release

After the required dwell/holding time, DT2 de-energizes. The booster assembly retracts and the cylinder releases pressure.

DT1 ON DT2 OFF
4

Return Stroke

DT1 de-energizes. The cylinder assembly retracts, hydraulic oil flows back to the reservoir, and one cycle is complete.

DT1 OFF DT2 OFF
