Carriage travel: with ball circulation guides

Mobile construction and installation of a mandrel carrier for housing 10 mandrels in line with the carriage

Provision for cooling the lubricating oil by means of a stainless steel coil inserted into the tank

Adjustable die holder

Bar support system

Tank with pump for lubrication

Manual opening/closing of the clamp operated by pneumatic piston

Compliance: The machine complies with EU conformity regulations.

DETAILED FEATURES

Operating system: The machine uses a hydraulic piston and patented technology for space optimization, ensuring linear movement.

Deep drawing aperture minimizes deflection of the support structure. Allows for a compact die length and double the useful pulling stroke.

Clamp return: A patented dual-circuit chain system returns the clamp to its starting position, permitting the hydraulic piston to be half the length of the useful stroke.

Pulling force: The pulling force is aligned with the drawing die.

Speed control: Manually adjustable speed from 0 to 16 meters per minute (0–16 m/min). Provides precise speed regulation and constant speed thanks to the hydraulic drive.

Tolerance: 1 mm tolerance.

Hydraulic system: Equipped with a proportional hydraulic pump.

Motor power: 9.2 kW – 380 V, 50 Hz

Carriage: Sliding carriage with ball circulation guides.

Die holder: Mobile construction and installation for a die holder accommodating 10 dies in line with the carriage.

Lubrication: Lubrication tank with pump included. Also features a cooling system with a stainless steel tube coil in the tank.

Adjustable die holder.

Bar support: Includes a bar support system.

Clamp operation: Manual opening and closing of the clamp by pneumatic piston.

Control panel: The machine is equipped with a control panel.

FUNCTION

The VM/TRI253S hydraulic drawing bench is designed for the cold reduction of the cross-section of a metal rod, either round or profiled, as well as hollow or cored metal tubing. The reduction in cross-section is achieved by passing the product through a calibrated drawing die and pulling it using a mechanical clamp with the required force to accomplish the reduction.
