ROEMHELD North America offers a rail-guided RWS die changing table for transporting heavy dies and molds. The solution is available in three versions for loads of up to 15, 25, or 40 tons per die. Electrically driven, the system is equipped with two different pull-push systems for the safe and automatic transport of dies to set up presses. It can be used to change dies and molds on all types of machines, including vertical forming and injection molding machines.
"RWS is ROEMHELD's answer to today's trend where loads in die and mold making are ever-increasing," said a company spokesperson. "This solution helps car manufacturers integrate numerous individual parts into increasingly large castings, for example in megacasting for frame or body manufacturing. They are processed with heavier dies in larger presses and punches. ROEMHELD understands these new requirements and is expanding its range of die weights to accommodate heavier loads."
The die-changing table is guided on floor-level round rails. These rails have a rolling resistance so low that loads of up to 5 tons can easily be moved manually by just one person. In addition, the rails are designed to facilitate precise carriage guidance and to prevent dirt deposits and tripping hazards in the floor.
Consoles that bridge the distance between the press bed and the die-changing cart make transport effortless. RWS has an integrated pull-push system that moves the dies onto and off the press bed via roller rails. A safety mechanism helps ensure that the loads can only be moved when the RWS die-changing table is firmly attached to the press or the storage space.
RWS is available as a single or tandem cart and can be used flexibly in a wide range of production scenarios. For example, it can travel between a storage space, a set-up station, and a single press. It can also shuttle between several bearing locations, set-up stations, and presses. Alternatively, it also enables several presses to be connected to just one changing table. This means that the presses are free during preparation and can produce right up to die change.
With this solution, ROEMHELD is able to meet the growing requirements of customers resulting from today's trend of employing connected presses and complete solutions. Dies of different sizes can be easily changed with one system because a standardized base plate is used. Semi-automatic and fully automatic die changes are possible due to the control system that is integrated in the cart and precise positioning. Other available features include integration with the press control, and the ability to combine with a rapid-clamping system for dies.
The amount of time needed for the actual changeover is also minimized because the die-changing table is equipped with integrated lifting bars and a pull-push system. Also important for operators: in the semi-automatic system version, the cabled remote control (wireless also available) enables simple, safe and centralized control of the cart.
"Compared to free-moving transport systems, the rail-guided die-changing table receives high marks with numerous advantages: maximum repeatability and precision of up to ±0.3 mm, lower energy consumption and space requirements and greater availability," said the spokesperson. "In addition, the installation of floor-level round rails generally places fewer demands on the factory floor."
