ECA pull clamp cylinder

Mold clamping system

These clamping cylinders offer a fast, safe and easy way to clamp molds or workpieces on (vertical) presses. The ECA single-acting pull clamp is a low-cost, cost-effective clamping system ideal for space-constrained environments.

ECA clamps are easy to install and are also suitable for retrofitting into existing systems. Wide range of tension forces and durable and compact design. There is hardly any distortion.
Pulling cylinders for metal stamping machines push down and secure the back plate of the die. In order to be able to use the clamps safely and easily even in hard-to-reach places, EAS offers two types of T-slot drawing cylinders for metal stamping machines:

the ECA and the MHC.

With both series, productivity can be easily increased and downtime can be easily reduced. If a more constant pressure is required, the double acting cylinder series MOD, MPR or the tilt clamp series MSR is recommended.

For standard SMW operations, the ECA clamps are a good choice. The ECA has a wider temperature range than the MHC and also has more capacity when it comes to clamping force. For heavier work, the MHC pull clamp cylinders are a better option. Both pull clamps are manually moved to the die in the T-slot. Due to the large clamping stroke, these cylinders can be used for back plates of different thicknesses.

FEATURES ECA

operating pressure 350 bar (5000 psi);
temperature range 5 °C to 200 °C (thanks to Viton seals);
tension force: 40, 60, 100, 160 and 250 kN;
clamping stroke: 8 mm.

KEY POINTS ECA:

single acting hydraulic SMW clamp;
user-friendly and easy to move, even for non-standardized backplates;
extensive range of standard products;
parking spaces available.

USAGE

The ECA clamps are manually moved to the die in the T-slot. In common SMW applications with non-standard backplates, four of these clamps are used on the press slide plate and four clamps act on the die holder.
Then the cylinders on the slide plate are connected to two single acting hydraulic circuits and all four clamps on the die holder are connected to one hydraulic circuit.

The air hydraulic EAS pump units are well suited for use with these single acting hydraulic clamps and can also be used in combination with hydraulic or air operated die lifters.
PSL parking spaces are available for neatly storing the ECA and MHC pull clamp cylinders and protecting their lifespan.
