Bellow Expanding Machine — VV TOOLS, Faridabad
Compact, robust semi-automatic bellow expanding machine designed for reliable production of metallic bellows and expansion joints in the 1″–4″ (inch) size range. Ideal for small-to-medium batch runs where repeatability, safety and ease-of-use matter.
Key features
Semi-automatic operation for fast, consistent cycle times with operator oversight.
Size capacity: 1″ to 4″ (ID/OD depending on part design).
Drive: 3 HP electric motor (user-specified as 3HP) coupled to a hydraulic gear pump for smooth, controllable expansion force.
Adjustable stroke and pressure control for different materials and wall-thicknesses.
Rigid frame and precision tooling mounts to minimize part movement and ensure concentric expansion.
Simple operator interface: start/stop, feed, retract, and emergency stop.
Safety guards and interlocks around tooling area.
Low maintenance gear-pump hydraulics — easy access to filters and service points.
Powder-coated body and industrial finish for shop-floor durability.
Branded and supported by VV TOOLS — Faridabad.
Typical technical specifications (standard configuration)
Machine type: Semi-automatic bellow expander
Capacity: 1″ — 4″ (inch)
Motor: 3 HP, 3-phase (standard)
Hydraulic: Gear pump driven, adjustable pressure up to user requirement (factory set)
Stroke: Adjustable (factory default example: 80 mm — configurable)
Cycle control: Manual hold + semi-auto indexing / pneumatic or hydraulic feed options available
Power supply: 415 V, 3-phase (typical; specify local supply when ordering)
Overall footprint: Compact bench/stand mount (dimensions vary with tooling)
Weight: Depends on tooling & options (approx. 200–500 kg range)
Safety: E-stop, guarding, pressure relief valve, limit switches
Note: Final specs (pressure range, stroke length, tooling dimensions, electrical supply, and hydraulic settings) will be tailored to the exact bellow geometry and material.
Benefits
Consistent, repeatable expansion with minimal scrap.
Faster throughput versus fully manual methods; lower operator fatigue.
Precise pressure control reduces risk of over-expansion or material damage.
Rugged hydraulic gearing for long service life and simple servicing.
Easy to integrate into small production lines or test benches.
Typical applications
Metallic bellows and expansion joints (exhaust bellows, silencer bellows, EGR tubes, corrugated hoses)
Prototype and small-batch production for automotive, HVAC, and industrial piping components.
Optional accessories / upgrades
Custom forming mandrels and dies for specific bellow profiles
Programmable PLC control for repeatable multi-step cycles
Pneumatic/hydraulic part clamp or chucking fixtures
Automatic indexing table or conveyor integration
Higher-capacity motor/hydraulics for thicker materials or larger expansions
