DETAILED FEATURES

Operating System: The system uses a hydraulic piston and patented technology for optimizing space, ensuring linearity with the drawing hole, and minimizing bending of the supporting structure. It allows for a compact die length and double the useful pulling stroke.

Caliper Return: A patented double-circuit chain technology returns the caliper to its starting point. This allows the hydraulic piston's length to be half of the useful working stroke.

Pulling Power: The pulling power is in line with the drawing die.

Speed Control: Manual adjustable speed from 0 to 16 meters per minute (0−16 Mt/m). It offers fine regulation of the speed and constant speed derived from the hydraulics.

Tolerance: The tolerance is 1 mm.

Hydraulic System: Features a proportional hydraulic pump.

Motor Power: 9.2 kW - 380 V, 50 Hz.

Carriage: Carriage sliding with ball circulation guides.

Hole Holder: Construction and movable installation of a hole holder to house 10 holes in line with the trolley.

Lubrication: Includes a lubrication tank with a lubrication pump. There is also a predisposition for cooling the lubricating oil with a stainless steel pipe coil in the tank.

Die Holder: Adjustable.

Bar Support: Includes a bar support system.

Pliers Operation: Opening and closure of pliers are operated manually by a pneumatic piston.

Control Panel: The machine is equipped with a control panel

FUNCTION

The hydraulic drawing bench VM/TRI253S is a machine used for the cold reduction of the cross section of a metallic rod, both with round or shaped profile, or of an empty or “animated” metallic tube. The reduction of the section is obtained by passing the product through a calibrated drawing die and pulling it, using a mechanical clamp with the force required to obtain the reduction of the section.

COMPOSITION OF THE DRAWING BENCH

The machine is composed of the following main components:

- Metal structure
- Carriage equipped with a hydraulically controlled clamp
- Carriage drive unit
- Hydraulic system
- Electrical system

Metal structure

The metal structure is composed of a recirculating ball guide.

At the end of the rails, a suitable sized plate supports t...
