Tool change vehicles
Transport and changeover of injection moulding tools
HUBTEX tool changers, with load capacities of up to 65 tonnes, help to reduce changeover times for press, stamping and injection moulding tools, thereby increasing production output. They are designed for confined access conditions, can handle heavy loads at very low table heights, and facilitate fast and safe tool changes directly at the machine. The size of the frame structure and the scope of assistance are adapted to the specific changeover situation.
Extremely low platform heights with simultaneously high load capacities
Thanks to its innovative chassis, every HUBTEX tool changer can carry very high load capacities with very low platform heights. This is achieved by installing several rows of smaller wheels, which are individually designed and calculated depending on the additional load.
Small dimensions maintained, load capacity increased
The tool changers from HUBTEX are characterized by their compact dimensions, as the entry situation for pressing and stamping tools or other machines is usually very confined. This is made possible by the individual frame structure of the vehicle.
Precise docking with assistance systems
Precise docking at the center of the press is a prerequisite for fast and reliable tool changes. This avoids the need to reposition the tool on the lifting table. The exchange vehicle approaches the press with the tool platform raised. When the tool platform is lowered, the docking hook moves into the holder on the press bed. The precise positioning can be covered by a variety of assistance systems. Simple systems such as a line laser at the control station for precise positioning of the transporter in front of the press bed in combination with a lift height indicator and distance display of the tool platform are just as conceivable as a fully automated positioning system.
Das sagen unsere Kunden und Partner
über unsere Produkte und Dienstleistungen.
A new multidirectional tool changer from the special purpose vehicles manufacturer HUBTEX was especially designed for the application at the Volkswagen plant in Wolfsburg Germany for transporting and changing injection moulding tools.
Features
The load is picked up by a lift mast with attached tool platform. The vehicle specification will always be individually adapted to your requirements. For example, a lifting range of at least 375 mm to 900 mm with a load capacity of 50 tons can be achieved. The pushing/pulling of the pressing tools is done via two thrust rods, which are driven by a push chain system. The thrust rods can be operated individually or together. The thrust rods are adjustable in length and can be exchanged. Alternatively, the thrust can also be realized with a spindle drive. The upper side of the tool platform is equipped with six exchangeable sliding strips.
A clear view of the changing process is particularly important when changing tools. For this reason, two operating concepts have become established. If the tool changer is required to make longer journeys around the factory site, it can be operated from a driver station. This usually has a high location in order to improve the overview of the changing process.
Alternatively, the vehicle may also be operated via remote control. The advantage of this variant is that the operator can walk around the vehicle to further improve visibility. A combination of remote control and cab is of course also conceivable.
The chassis is based on a solid welded construction. As a rule, the drives are fitted with double tires and have a large steering angle. An oscillating drive ensures constant ground contact for all wheels. On the load side, the load wheels are configured in rows with a small wheel cross-section in order to achieve the minimum possible height of the lift table. This ensures a low entry height under the tools. The exact design depends on the requirements of the changing situation.
