Hydraulic press – line for production of conveyor belts

Hydraulic press with the belonging equipment is intended for productiron - vulcanization of conveyor belts. Conveyor belts can have smooth or ribbed surface.

The speciality of the press is execution of the pressing with great number of hydraulic cylinders distributed in groups. The mooving upper heated plate has the same function of pushing table and provides even pressure distribution on the surface of the product.

Heated plates are made of sheet steel with drilled channels connected into heating fields. The appropriate location of the channels and fields provides even temperature on the surface of the plate. On the ends of heating plates are separate fields for cooling.

Hydraulic clamps, placed on the entrance and exit of the press, are mooving vertically and horizontally and provide detachment of belts from heating plates.

Mooving supporting rollers provide easier transport of the belt through the press.

Advantages of the press:

• possibility to produce thinner belts (5mm)

• evenly distributed surface pressure

• even temperature across the surface of the heated plates

• possibility of effective detaching of belts from heated plates

• vertically mooving tension clamps

• possibility of degassing of surface air bubbles

Control of the press - line:

The operation of the press with the belonging equipment is controlled by a process controller and provides:

• choice of operation mode: manual or automatic

• input and display of technological parameters (temperature curve, curve of the working pressure and duration of the cycle)

• storage of technological processes of individual products

• teleservice (modem)
