Provision for cooling the lubricant oil with the insertion of a stainless steel tube coil in the tank

Adjustable die holder

Bar support system

Lubrication tank with pump

Manual opening/closing of the clamp, actuated by pneumatic piston

Compliance: The machine is built in accordance with EU conformity regulations.

DETAILED FEATURES

Operating system: The system uses a hydraulic piston and patented technology to optimize space, guaranteeing lineal stroke.

With the drawing hole, it minimizes flexing of the support structure. It allows for a compact die length and a double usable pulling stroke.

Clamp return: A patented double-circuit chain technology returns the clamp to its starting point. This allows...

The hydraulic piston length to be half of the useful stroke.

FUNCTION

The VM/TRI253S hydraulic drawing bench is a machine used for cold reduction of the cross-section of metal rods, either with round or shaped profile, as well as hollow or “live” metal tubes. The section reduction is achieved by passing the product through a calibrated drawing die and pulling it using a mechanical clamp with the required force to achieve the section reduction.
